How about some ways to create a more peaceful day? One where you can allow yourself to be more relaxed and happier. The first step is the realisation that you are in control of your day. You can create the perfect workday if you are willing to put in the effort. Here’s how you can do it… Do less. It is very difficult to have a relaxed workday if you have too much going on. Instead, learn to reduce what you do, but choose the most impactful tasks and projects — the ones that will mean the most over the long term. Choose the three important things to achieve each day. Those are the three things you can do today that will have the most impact on your tomorrow, and the rest of the week. Create a morning routine. And make it a relaxing one. That could include some of the things below, such as exercise, a hot bath, or quiet working time. It could mean getting up earlier so you aren’t rushed, having a quiet cup of coffee, or journaling. Choose things that will ensure you start the day perfectly. Prepare the night before. An evening routine is also essential to starting your day right. This might include things like choosing your three Most Important Tasks for the next day, so you know what you are going to do when you wake up. It might mean getting your clothes ready or getting a jump start on preparing your lunch. Start the day with a relaxing shower. A hot shower can not only rejuvenate you, but it can be a perfect way to start off the day. It gets you in a relaxed mood, which is much better than starting the day stressed out. Get in some morning exercise. You don’t have to do it every single morning, but if you can fit it in most mornings it is a great start to your day. A nice morning run is a great way to energise you and gives you a sense of well being and accomplishment. Work when it’s quiet. Whether you go in early or stay late, use the quiet time to focus and get heaps done without the interruptions. Starting work early can also mean you have the opportunity of finishing early if your workplace has flexible working hours. Create a clutter-free environment. A clutter free desk can help you have a clutter free mind. Only have the things you really need in your line of sight. Too many items can cause a visual distraction. Clear your walls of everything but a nice piece of art or a family photo. Clutter-free surroundings create a peaceful working environment. Turn off the distractions. That means phones, email notification, instant messaging, anything that will break into your focus and make you jump from one thing to another. Cut back on your commitments. Evaluate all the things you have got going on in your life, and see what isn’t essential. This means choosing 4-5 essential things in your life and trying to eliminate the rest over time. Cut out meetings. If you have the ability to opt out of meetings, do so. They are generally a waste of time. Usually, the content of a meeting could be accomplished with an email or an Instant Message. Cutting out meetings could free up a lot of time and make your workday more relaxed. Single-task. Focus is everything. Constant interruptions or switching between tasks wastes time. So, focus on one task at a time for productivity and efficiency. Take breaks and stretch. While focusing on one task at a time is important, it’s also important to take breaks when you can. Get up, stretch, get a glass of water. Massage your shoulders, neck and head. It keeps you relaxed throughout the day. Go for a walk. Taking a walking break can help you gain a refreshed perspective. It gives you time to think and to get a better overall picture of your workday. Plus it gets the blood circulating. Eat lunch how you like. If you are a social person then catch up with friends or have a lunchtime meeting. But if you are the quiet type, don’t be afraid to take time out with a book, meditation, or reflection. Do mini-meditations. This doesn’t require a mat or a temple or soothing tapes or anything. Just sit where you are, close your eyes, and focus on your breathing — on your breath as it comes into your body, and then goes out. This can help you to centre yourself, no matter what is going on with work. Learn to focus on the present. Instead of worrying about what you have to do in the future, and reliving things you did in the past, focus on what you’re doing right now. This can be difficult, as our minds have a tendency to wander to other things, but it’s simply a matter of practice – be aware of where your mind is, and when it drifts to other things, gently bring it back to the present. This helps keep your mind in a peaceful place all day long. Roll with the punches. There will always be things that go wrong. What is important is how you react to them — do you go all Drama Queen, and get stressed and upset? Or do you accept what has happened, and make a calm decision about what to do now? When things get overwhelming, take a step back to get some perspective, and realise that in a few months, none of this will really matter much. Then take steps to eliminate the non-essential and focus on what’s really important. “There’s never enough time to do all the nothing you want.” – Bill Watterson, Calvin and Hobbes Contact JSR Refrigeration and Air Conditioning Today!

An efficient HVAC (Heating, Ventilation, and Air Conditioning) system plays a vital role in maintaining optimal indoor conditions. In this blog post, we’ll explore the significance of HVAC systems during winter in New Zealand and provide useful tips to maximise their performance. 1. The Importance of HVAC Systems in New Zealand New Zealand’s winter weather can be unpredictable, with temperatures varying across regions. While some areas experience mild winters, others face colder climates with occasional snowfall. Regardless of where you are, a well-functioning HVAC system ensures that you and your loved ones stay warm and comfortable indoors during the frosty season. 2. Selecting the Right Heating System A. Heat Pumps: Heat pumps are a popular choice in New Zealand due to their energy efficiency and versatility. They provide both heating and cooling capabilities, making them suitable for year-round use. During winter, heat pumps extract heat from the outdoor air and transfer it indoors, effectively heating the space. B. Central Heating Systems: If you have a larger property or prefer a centralised heating solution, consider installing a central heating system. These systems distribute warm air or hot water through a network of vents or pipes, providing consistent heating throughout the building. 3.  Maintaining and Optimising Your HVAC System A. Regular Maintenance: Schedule professional maintenance for your HVAC system before winter arrives. A trained technician will inspect and clean the components, ensuring efficient performance and identifying any potential issues that need addressing. B. Air Filter Cleaning/Replacement: Clean or replace your HVAC system’s air filters regularly. Dirty filters can obstruct airflow and reduce the system’s efficiency. Clean filters promote better indoor air quality and help the system function optimally. C. Programmable Thermostats: Invest in a programmable thermostat to regulate your HVAC system more effectively. Set lower temperatures while you’re away or sleeping and raise them when you’re at home. This practice helps conserve energy and reduce heating costs. D. Weather stripping and Insulation: Ensure your home or workplace is properly insulated and weather-stripped to minimise heat loss. Insulating walls, attics, and floors, as well as sealing gaps around windows and doors, can significantly improve energy efficiency and maintain a comfortable indoor environment. 4. Energy Efficiency and Cost Savings A. Smart Technology: Consider integrating smart technology into your HVAC system. Smart thermostats and sensors allow you to monitor and control your heating remotely, enabling energy-saving adjustments and reducing unnecessary heating B. Zoning Systems: If you have a larger property or multiple floors, a zoning system can optimise energy usage. This system divides your home into different zones, allowing you to adjust temperatures independently in each area. C. Energy Star Certification: When purchasing HVAC equipment, look for Energy Star-certified products. These appliances meet strict energy efficiency standards and can help lower your energy bills while reducing your carbon footprint. Overall An effective HVAC system is crucial for maintaining comfort during winter in New Zealand. By choosing the right heating system, conducting regular maintenance, optimising your settings, and improving energy efficiency, you can ensure a warm and cosy environment while keeping energy costs under control. Prioritising your HVAC system’s performance ensures that you and your loved ones can enjoy the winter months without any concerns about indoor comfort.

That’s a lot of families which need to be prepared this summer – read on to find out how. Visit your GP New asthma action plans were released by the Asthma and Respiratory Foundation NZ in November, so now is a great time to get a new plan based on the latest best-practice. Ask your GP to review your asthma action plan. Don’t forget medications It’s important to stay on top of your medication during the summer, and take preventers regularly if prescribed. If you’re going away on holiday, make sure your prescription medications will last until you arrive back home, and always take extra with you. Pack everything else you need, including a spacer (if your inhaler allows) and peak flow meter. Temperature and weather changes Changes of temperature and weather can be a trigger for people with asthma. Be aware of change of climate and/or temperature if you’re planning to go on a holiday. If you know that certain weather affects your asthma, you may need to increase your medicine during that time. Pollens, moulds and fungal spores Pollens can come from grasses, trees and shrubs. Grasses and weeds are so widespread and have such a long season that they usually cause the major pollen problems in New Zealand. If you have asthma that is triggered by these allergens, try and avoid them, or minimise exposure to them where possible. Smoke Around three-quarters of people with asthma become wheezy when in a smoky room. During the summer season stay away from second-hand smoke from cigarettes at social occasions, and also remember to avoid smoke from bonfires at night, or smoky barbeques. Animals A high proportion of New Zealand families have cats and the allergens they produce tend to stay in the house for long periods. Dogs, rabbits, guinea pigs and mice can also cause problems in some people. If animals are one of your triggers, when visiting friends or family who have furry animals, take extra medication beforehand, or ask them to visit you. A Sensitive Choice® The Sensitive Choice® programme in New Zealand is managed by the Asthma and Respiratory Foundation. The programme is designed to help people easily identify products and services that are asthma and allergy-friendly.

So, what can you do to stay cool and relax when the heat starts getting unbearable? Firstly, best way is to have air conditioning which keep your home cool, but everyone can not afford it, so here are some free tips which can keep your home cool in this hot summer: 1. Draw blinds or curtains Draw blinds or curtains on windows and doors to keep sunlight out during the day and especially on windows and doors that get direct sun. 2. Keep windows open while cooking and use an extractor fan to reduce steam and heat. 3. Ventilate your home keep doors or windows open at opposite ends of the house to create a through-draught, or cross ventilation. However keep the front door and windows lock and closed if possible for security reasons 4. Swap your sheets Use cotton sheets and pillow covers as cotton fabric breathes easier and stays cooler. 5. Let the night air comes in Temperatures may drop during the night. So try to open windows for sometime before going to bed. You can even keep your fan on so that air can ventilate in the room and other surrounding areas. Contact JSR Refrigeration and Air Conditioning Today!

The monster tropical cyclone is looming near New Caledonia after crashing through Tonga on Monday night, leaving thousands of homes flattened and entire islands cut off. The deadliest tropical cyclones to hit the South Pacific Tonga on ‘long road to reconstruction’ after Cyclone Gita MetService meteorologist Claire Flynn told Newshub the storm is evolving as it moves down. “When you’re up in the tropics it’s a tropical cyclone, which means there’s an eye of the storm – and the strongest winds are closest to eye. “But it will transform into a mid-latitude cyclone as it comes south. The strongest winds can cover a much broader area. It can be much more widespread.” Ms Flynn was careful not to predict specifics – saying the highest wind speeds and rainfall cannot yet be ascertained – but says the whole country should be ready to bunker down if necessary. “The size of any impact will be highly dependent on where it hits.” The storm is still “well up in the tropics”, but will curve around New Caledonia and towards the country on Friday night, hitting next Tuesday. Gita is currently a category 3 storm, but as it evolves, it will lose any category status. That doesn’t mean it won’t be a serious storm, Ms Flynn adds. Mid-latitudes simply aren’t measured by categories – instead by the speed of their winds and rainfall. There is an unrelated severe weather warning for the West Coast on Friday and a weather watch on Canterbury High Country with heavy rain expected – but if you’re in the upper part of the country, forecast for warm and calm conditions over the weekend, best make the most of it.

If you are unable to answer a few essential questions before buying one, you’ll likely regret your decision later. We all know that summer can be tough because of the heat, but adjusting your A/C unit is a relatively straightforward process. The hard part is deciding what to do if you don’t have an A/C unit or want to replace the current one you have. What requirements do you have when making a choice? How do you decide which model to prefer compared to the other? The four questions in this article will help you make the right choice. If you already know the answers, you’ll pass with ease. 1. What system should you choose? Three options to choose from due to simplicity: Split-system Air Conditioning/Heat Pump system: Most common Aircon/Heat pump found in households. This system has one unit or interior split where you turn on the system and cold air flows out. The second unit is usually located outside the home. The strength of the split-system is that it’s a powerful system, including providing energy efficiency through both cold and warm airflow. The drawback to this system is the complex installation process. Even though it is not a super complex process, it is more difficult to install than other options. They come in different type: Wall mount, Cassette type, Ceiling suspended, Bulkhead, floor console, Multi room etc. Central Ducted Heat Pump Systems: Ducted Central Heat Pump and Air Conditioning Systems are designed to provide whole home central heating or cooling at a constant temperature throughout the whole house. Ideal for installing in new homes or retrofitted into existing homes, it is the ideal cost-effective and energy efficient solution for year-round comfort. Ducted Central Heat Pump and Air Conditioning Systems are whisper quiet, and with only its grilles visible, it is the perfect unobtrusive solution for heating or cooling multiple rooms at the same time. The addition of optional Wi-Fi Zone Control will enable your Ducted Central Heat Pump System to program and control individual zones, providing heating or cooling only to the rooms that require it. Built-in sensor functions monitor room temperature to maximise energy efficient use of the whole system throughout the home or just those rooms where it is needed. Portable air conditioning: These units look a bit like dehumidifiers in a rectangular shape on wheels, with a corrugated hose that you put through an open window to the outdoor area. Portable A/C are not super-efficient, but a quick solution to cooling down a small room (20 square metre or less). Making the right choice will depend on the goals for the air conditioner. Basic models are portable and quick solution, while more advanced versions (two units) offer more efficiency in terms of power and energy. 2. What kW power do you require? We all know energy plays a big role when looking for a cooling system. As cost of living has increased in NZ, it’s important to look for a reliable energy efficient air conditioner. Electricity is measured in kW in New Zealand. To estimate electricity power, it’s 0.086 kW per square metre. For example, if you multiply 0.086 kW to 30 square metres, you’ll get 2.58 kW. Meaning, this would be the power required to cool a room with an A/C unit. The unit’s power will increase your electricity bill: the more power usage, the more you’ll have to pay. With this being said, bear in mind that an air conditioner with excessive power won’t have better climate control in your home. It just means more expense for your unit and a higher energy bill. 3. What energy label should I choose? According to Consumer NZ, all new A/C units from July 2021 will display a Zoned Energy Rating Label (ZERL). The ZERL provides clear information on yearly energy usage of an A/C unit in KWh, climate zones for heating and cooling on specific A/C brands and model numbers. Most importantly, the label provides energy efficiency rating (up to 10 stars) to help you decide which model will best fit your needs and certain environment. For every A/C unit, The kWh figures besides the stars icons will show how much kWh is being consumed per year. The less kWh number on the label, the less it will cost to run. Using the ZERL will help you reduce the energy consumption for up to 30%. 4. What other factors to consider looking for an air conditioner? Also consider these factors when choosing an air conditioner: Home Energy Rating: Insulation of your home through walls and floors can impact how quickly you can lose cold air. Logically, if your home is not properly insulated, your A/C will have to work harder to maintain the cold airflow in your home. Thus, more hard work leads to higher energy bill. House Orientation: Your home’s positioning influences the exposure to direct sunlight The size of the windows and outer doors – in square metres. Outside wall length The number of people staying in a normal room Want help choosing an air conditioning? Ask our lovely team at JSR about choosing cooling system of your home.

Unsurprisingly, heating is expensive and normally accounts for 30% of a households energy consumption during winter. For spaces you need to keep heated regularly, it’s worth thinking about purchasing a fixed heating system such as a heat pump. Heat pumps are more energy efficient than any other form of heating and can help reduce your power bill over the winter months. Heat pumps are very efficient as they have a very high ratio of heat output to energy input. Hitachi’s heat pumps are incredibly efficient, boasting some of the highest energy star ratings on the market. Undersized or oversized heat pumps will increase your power usage. To maximise the heat pumps efficiency it’s important to get the right sized heat pump that matches the room size. An undersized heat pump uses more power working harder to maintain the temperature setting. An oversized heat pump will use more energy to operate than required. Hitachi has a wide range of heat pump options with a range of capacities and features available to suit your needs. To find out what size heat pump you need Hitachi’s Heat Pump, contact one our JSR’s heatpump specialists to suggest the right options for you. In regions where the temperature drops significantly for long periods, like many parts of the South Island, you might want to set your heat pump to a low temperature and keep it running day and night. This can be more economical than turning your heat pump on when you are in the room as it will require a long period time using significant amounts of power to bring the room to the desired temperature turning it on multiple times a day. In milder climates such as the upper North Island it is usually better to only turn the heat pump on when it is needed unless it is very cold. You can purchase Hitachi’s premium 7 day remote which allows you to track power usage, this will guide you to the ost efficient way to run your heat pump. Here are some other tips to keep your heat pump running costs down and system running efficiently: 1. Decrease your thermostat by a few degrees – adjusting the thermostat down slightly in winter to help the unit save energy and money. Hitachi’s offers a 7 day programmable thermostat allowing you to adjust temperature for different times of the day. 2. Keep your filter clean – Clogged filters make your heat pump work harder than usual. Cleaning them will mean cleaner air for your home and more efficient air flow, reducing energy consumption and saving you money. 3. Clean around outdoor condenser unit – keep debris such as leaves and dirt away from the outdoor unit to keep it running efficiently. 4. Vacuum indoors regularly – this will keep dust around the home to a minimum, keeping your filters cleaner for longer.

There are many ways to reduce your energy usage and keep your bills low. Here are four tips to help you save energy this winter: 1. Invest In Energy Efficient Curtains Older Kiwi homes are notorious for their chilly, damp atmosphere. Preparing your house to withstand the winter’s fury can not only help you save money on energy costs, but may also provide significant health advantages. As the weather gets colder, you’re likely to turn up the heaters to keep warm and toasty. You may not know that a home with no curtains loses up to 31% of its heat through its windows. This means some of that precious heating is escaping out the window! Curtains can make a difference by conserving lost heat in the home. 2. Turn Appliances Off Regularly One of the easiest ways to save energy is simply by turning off appliances when you’re not using them. This includes lights, TVs, computers, and any other electronics. If everyone in your household makes a conscious effort to do this, you’ll see a significant decrease in your energy bills. Do you leave some of your appliances in red light? That is what call a standby mode. Standby mode on your energy-using appliances is often costing you more than you would if they were not on. For example, the lights in your house will be used for 2-4 hours a day more in winter than in summer. The more lights you leave on, the bigger the difference in energy usage you will notice, resulting you in more cost overtime. So switch them off. 3.  Switch to Energy-Saving Lightbulbs To save money in the long run, switch to energy-efficient light bulbs like compact fluorescent lamps (CFLs) or LEDs’ light-emitting diodes. These may have a higher price tag than the average incandescent bulb does, but this is because they can provide much more energy efficiency for that money. Energy-saving lightbulbs use up to 85% less energy than your common incandescent bulb, and you’ll save up to $100 to $300 over the course of the bulb lifespan. Plus, these bulbs also have a longer lifespan, so you don’t have to replace them often. 4. Keep An Eye On Your Heat Pump’s Temperature A heat pump is tempting to blast to max, but not only does it use more power, it also makes it hard to control your electricity bill. Luckily, there are a few strategic things you can do that can keep you both comfortable and economical with how much electricity you’re using. Since heat pumps will keep working for over two hours once they switch on, it’s worth setting a timer so that you can turn it off when you’re not using it. And as well as saving energy, keep the thermostat temperature in your home between 18 °C and 21 °C. This helps keep the room drier and saves power without making the heat pump to work more. It also makes it easier to calibrate your heating and cooling settings to be more consistent because going from hot or cold can waste energy. Want heat pump installed or maintained at your place?

We’ve finally left the cold winter months behind, and summer is approaching quickly. As we prepare for another hottest New Zealand summer, it is important to know few tips on how to get your A/C ready for summer.  You don’t want your first summer day of the year to be really hot if your A/C isn’t performing at the expected level. By Team JSR Here are 6 tips to keep in mind to ready your A/C when hot, humid weather arrives. 1. Check your outdoor air conditioner before turning it on If you cover your A/C during winter, make sure you remove the cover before using it. When you’re not using your A/C, it’s great that you are covering your A/C to prevent sticky substances, leaves, and rubbish. It’s especially great for dirt or tree branch not hanging themselves around the shroud fan, which could burn up the fan motor. If you fail to remove the cover before turning on your A/C, you could end up damaging mechanical parts, which can then lead to costly repairs. Outdoor Air Conditioner 2. Make sure your fuses or circuit breaker is switched “ON” at your home electric panel Many families prefer to turn off the power of the outside unit so the A/C doesn’t accidentally operate during winter. This is quite an easy thing to forget months later when you are ready to use your A/C. Home Electric Panel 3. Inspect your air filter in your air conditioner If dirt builds up on your air filters, it will reduce the efficiency of your air conditioner as it’ll struggle to circulate the cool air into your space. Failing to clean air filters will drive up your electricity bills through the season and add pressure to your A/C systems. Air Filter of Air Conditioner 4. Wash off the loose debris from your air conditioner A similar process of dirty air filter applies to your A/C. If outdoor ac coils are dirty, air cannot flow through the system and will reduce efficiency. You can use a low-pressure hose to clean outdoor ac coils. Apply a little pressure with your finger over the nozzle to clean loose debris and keep A/C performing at its best. Air Conditioner Coils 5. Switch off the humidifier if you haven’t Some Humidifiers are not created to stop working during the cooling season. If your humidifier doesn’t stop, turn the humidity control to its lowest level. If your humidifier has a damper, close that too. This will give you a certainty that cold air isn’t being wasted. Humidifier 6.

Especially chilly mornings when you’re out and about, you would wear a warm coat, beanie, a scarf to keep cold wind away from the body. And after a long day, you’ll use a heat pump to keep yourself warm. A heat pump can really help to keep your house comfortable when the temperature drops. So, when should you think about replacing it? Maybe you’ve noticed that it doesn’t seem to heat your home as well as before. As all appliances eventually break, and heat pumps are no exception. Still, you can get a long lifespan out of one, given that it’s regularly serviced and in the right climate. The lifespan of your unit will depend on where you live and how often it’s used. Remember that heat pumps that are regularly services will last longer compared to the one that is not. Old heat pumps, even if they are well maintained, are prone to technical problems. Look out for these 7 signs if you’ve been wondering when it might be the best time to replace your heat pump. If you recognise any of these signs in your heat pump, discuss with your local heat pump professional, as an inspection and advice is highly recommended before buying a new one. 1. Heat pump has inconsistent hot or cold air flow even after temperature settings One of the most common problems with an older heating/cooling unit is that it ceases to produce the required degree of heat or cold. The air coming out is still regular, just as before, but at lower levels. From regular use, for the most part, you may experience cool air on a warmer setting. If you experience no change in temperature, that would be a sign for you to inspect the cooling issue. A common issue could be low refrigerant levels. However, if the unit is set to produce hot air when is producing cold air, your compressor could be damaged. Rapid change in temperature is a sign that something is wrong with your heat pump. A proper functioning heat pump will provide consistent air temperature at the desired temperature setting. Do certain areas of your room are being warmed up? And other areas are not getting heat at all? It might be the time to replace your heat pump. If inconsistent cooling persists in your heat pump, check the filters, valves, condensation drain line, and coils. If worse comes to worst and the issue doesn’t resolve itself, then a new heat pump may be on the cards. 2. Heatpump Weak or barely flowing air When your heat pump is on and working, there should be little or no warm air coming out of the vents. If you start to notice that there is significantly less warm air than what is normal, it could be a sign of malfunctions in the compressor. If your home is still too cold, there might be a problem with your air conditioning. The system is meant to work at a certain level of temperature, and it’s rare that this will happen. Check filters first, but you might need to get a new one. 3. Spouting unwanted noises and smell If you listen carefully to your heat pump, you’ll hear nothing. Indicating your heat pump is running almost silently and efficiently! If that pattern changes throughout its lifespan, and you start hearing weird noises, it might be the time to act. Sometimes small noises could indicate that your heat pump might just need repairs. Or possibly the fan isn’t functioning, parts may have become loose, or the machine system has been clogged with grime and dust. However, if you’re hearing unusual noises like buzzing, hissing, popping, shrieking or vibrating noises, this could be referring to a serious problem that you might need to replace your heat pump! The same scenario is with unwanted odours! If your heat pump is spewing extremely unpleasant smells, it’s indicating something with wrong with your unit and should be addressed immediately. Foul odours from heat pump occur when either the heat pump’s insulation has become damaged or the mould has grown in the ductwork. Once dirt or mould has accumulated in the heat pump, the heat pump will circulate the contaminated air in your home, which will cause health concerns for your family. So never ignore the bad smells. Strange smells usually mean that you need to change your filters. But if that doesn’t work, it might be time to replace the unit. 4. Heat Pump Leaks or Produces redundant moisture Once in a while, for some types of heat pumps, there may be small amounts of water dripping/condensation on the unit outdoors. This is completely normal and just happens from time to time. Mostly, your heat pump should stay dry regardless of whether it’s not being used. But if you notice moisture inside, sudden condensation or a leak, it may be time to replace your heat pump. For safety reasons, get a heat pump technician to inspect your heat pump right away, as electrical systems and water don’t go well together. As a matter of fact, some heat pump units may have refrigerant unit spring. If this leaks, you want the technician to handle it, as the last thing you want to do is ignore a refrigerant leak since it can pose several health risks if not dealt with. Your heat pump technician will locate the source of the leak and will let you know cost-friendly action you should take next. 5. Your Heat pump is short cycling (random turn ons and offs) Your heat pump has the tendency to maintain the temperature throughout your home; which is normally done through cycling the on and off button. However, has your heat pump developed a habit to completely switch off aimlessly? Or is it struggling to switch itself on? If this notice these scenarios often, your unit is faulty. Short cycling adds more pressure on the heat pump, and can result in a total breakdown if not handled in time. If you’re struggling with this issue, call a technician immediately. If by any luck, it could just be a blown fuse. Or it could also mean it’s time for a new heat pump. 6. A huge increase in your monthly power bills Frequently, the biggest give away about any heating pump lies in the energy bill for your property. Has the bill had a sudden increase and not sure what the cause of the source might be? Conduct an ‘energy audit’ and powerful way to get the facts on what has been causing your energy bills to rise. Don’t make critical decisions without figuring out the source of the problem first. If all the answers leads to the heat pump, then you need to figure out why your unit has decreased in efficiency. Is it overworking? Perhaps cooling system is weakened since it maintains cool temperature, which will only lead to higher energy costs. We recommend that you carefully clean the air vents. Clean the dirty air vents, replace filters and check for lumps or knots in the condensing coil. If these suggestions do not help reduce energy, your heat pump is nearing the end of its working life. You’ll need to replace it soon. 7. Your heat pump requiring constant repairs (and expired warranty) Is your favourite heat pump costing you expensive repairs more frequently? Ideally, your heat pump only needs servicing once a year to keep it in top shape and running efficiently throughout the year. But if you’re requiring service or repairs more than a few times per year, it may be the right time to replace it. Newer heat pumps provide more efficiency and more energy saving options. Normally, you can, could consider a major repair or a part replacement. However, when repairs are required again later on in the unit’s life, it signals bigger issues to come. If your warranty protection expires and your heat pump requires complicated repairs (which could have similar cost to a new heat pump), that definitive sign that you should shop for a new heat pump. There you have it. We hope these 7 signs help you out if you need to replace your heat pump. Remember to act as soon as you see these signs, so your upcoming kiwi summer is trouble free, relaxing and energy friendly.

Pollen, dust, mould spores and even animal hair can trigger sneezing, watery eyes and discomfort indoors. The good news is that JSR Air Conditioning & Refrigeration can be one of your best tools in keeping allergens at bay. Here are seven ways it can help. 1. Filters out pollen Your air conditioner’s filters are designed to trap pollen particles before they circulate through your home. Clean filters mean cleaner air, making a noticeable difference during peak pollen season. 2. Reduces dust Airflow from a regularly maintained system helps reduce dust build-up. With less dust settling on your furniture and floors, there are fewer triggers for allergy flare-ups. 3. Controls humidity High humidity creates the perfect environment for mould and mildew. Air conditioning regulates indoor moisture levels, keeping your home less hospitable to these common allergens. 4. Cleans the air Modern units use advanced filtration technology to remove airborne irritants such as pet dander and animal hair. This makes a big difference if you share your home with furry companions. 5. Keeps windows closed When it gets warmer, it’s tempting to open the windows for fresh air. Unfortunately, this lets pollen and pollutants inside. Running your air con instead keeps your space cool without bringing allergens indoors. 6. Removes pollutants Beyond allergens, air conditioning can also help filter out bacteria, smoke particles and other pollutants, leaving your indoor air fresher and healthier. 7.

For many kiwis, summer means giving a couple of snags off the barbie, hours of entertainment with hitting the swing ball set in the backyard or dipping in the pools with your mates. But some days are harsher when the hot heat from the sun isn’t quite fun to lay under, forcing you to crank up the air-con, the only option you’ll have. We’ve gathered 10 tips to help you and your home keep cool, saving you costs, and being kind to the planet: 1. Close your home blinds Block the sun heat by closing your curtains or blinds, specially where the sun is facing. Your home should cool off significantly using this tip. To make it even better, invest in a stylish block-out curtain, helping you keep out hot sunlight and reduces heat by creating a perfect oasis for you to relax after a tiring workday. 2. Block the heat The more heat you stop from entering your home, the less you’ll have to spend on cooling. Shade your windows or walls using external coverings. E.g. blinds, awnings, or large potted plants. Planting large potted plants or sometimes deciduous trees adds a protective shade over your home throughout summer. 3. Increase Thermostat Temperature by 1°C Do you use your heat pump for cooling? Set the thermostat to 22°C and 24°C. By just increasing the heat pump temperature from 1°C, you will reduce the cost of your appliance. If you’re looking to upgrade your heat pump or air conditioning system, choose a high energy star rating system. Consult with your local HVAC technician to help you choose the system for your home. 4. Shut doors and seal any openings. Close doors of the areas where you don’t require cool air to go. Seal any openings around doors & windows. For doors gaps, you could also place a cloth or towel for cool air to not escape. Drink icy-cold drinks, take a cold shower, eat ice cream to cool your body without needing an AC system on. 6. Enhance your pedestal fan Don’t have an AC system? Don’t worry! Gather tons of ice cubes from the fridge, put the ice in a bowl, and place the bowl of ice in front of a fan for an icy-cool breeze that won’t break the bank. 7. Use Cotton Fabric During summer, our clothes get hot, sweaty, and unbearable. A quick fix would be wearing cotton clothes. Cotton allows breathability through your skin, keeping you cooler throughout the hottest days. To help you sleep better, cotton bedsheet will keep you cool at night, making sure your lovely sleep isn’t interrupted from overheating. 8. Swap out your lightbulbs If you’re struggling to keep your home cool and can’t figure out why, consider that old incandescent lightbulbs could be the culprit. Many homes still rely on them. These bulbs generate a significant amount of heat, so transitioning to energy-efficient alternatives can contribute to cooling your home and result in substantial savings on energy costs – a double victory!

We’ve gathered 9 tips to help you run your Heat pump or Air Conditioner (A/C) efficiently to prepare you for the hottest New Zealand summer. By Team JSR Here are 9 tips you can start using today to ready your Heatpump or A/C when hot, humid weather arrives. 1. Clean Inside and Outside Not just saving money on operating costs, it’s highly recommended for safety. Over winter, your heat pump collects dust and grime, and this impacts the efficiency when you switch to the pump’s aircon feature. Test all units and clean them thoroughly, including taking the filters out to clean and replacing them as required. Have your air conditioner or heat pump serviced by a professional at least every year. Heatpump Or A/C Cleaning 2. Don’t use A/C or Heatpump too early While it may be tempting to turn the air conditioning ON at the first sign of a hot day, doing this too early in the summer can result in wasted energy and higher bills. Using a fan lets you stay cool without needing to lower the temperature of the entire house. This will save you money and electricity. Cool OFF With Fan 3. Keep your AC at the desired temperature Want to cool your home to 24°C? Lowering temperature won’t cool your home quickly. Your AC cools your home at the same rate whether you set it at 24 °C or 20 °C. Set your AC to the desired temperature to prevent it from cooling your home more than necessary, so you don’t have to pay extra on your bill. Cooling with Heatpump Remote Control 4. Close blinds and curtains to block excess heat Sunlight streaming through closed windows can heat your home. If you’re out during the day when leaving in the morning, try closing as many curtains and blinds as you can to block out excess heat from the sun. Closing Blinds and curtains will reduce how much energy will be required to cool your home when you return home. Blocking Excessive Heat 5. Reduce the use of appliances that generate heat If you’ve got your air conditioner to cool the house, try not to use appliances that let off heat into your home, like a dryer and the oven. On hot days, these appliances may make your air conditioner work harder to cool your home. Cooling your home works the same way as heating it, but in reverse – you want to keep the cool air in your home! Close windows, doors, and pull-down blinds or close curtains if you have the sun streaming in. Reduce uses of all appliances during summer 6. Close rooms that don’t need cooling When you’re home alone, close off the excess space that doesn’t need cooling when using your air conditioning. Close OFF excess space 7. Turn off TVs and Electronic Devices Think about your appliances too. When cooking large meals, close off the kitchen from the area you’re cooling off. When you are not watching your TV Or working on your computer, don’t leave them on as these electric devices can generate a lot of heat. Tv Appliance 8. Close bathroom doors when showering When showering, make sure the bathroom door is closed and leave the windows open during and afterwards to cool the bathroom down. If you don’t do this, your air conditioner will have a hard time dealing with a hot and humid bathroom environment. Bathroom Door 9. Insulate Floors and Roofs If you haven’t Remember, proper insulation not only warms your home during winter but also keeps it cooler during the summer. Consider Insulating the floors and the roof of your home. Insulate-floors-and-roofs Need help maintaining your Heatpump and A/C?

Take Control With JSR Refrigeration & Air Conditioning, Hamilton By Team JSR • February 5, 2026 • 3 min read Hot, sticky nights and overheated days can make summer feel unbearable. If you are constantly uncomfortable in your own home, it may be time to take control of the heat with JSR Refrigeration & Air Conditioning. Effective cooling does more than improve comfort. It can help you sleep better, stay healthier, and enjoy your home again. Better Sleep Starts With Better Temperature Control Excess heat is one of the biggest causes of poor sleep during summer. When your bedroom stays too warm, your body struggles to cool down, making it harder to fall asleep and stay asleep. A well cooled home helps regulate your body temperature, allowing you to reach deeper, more restorative sleep. Better sleep means improved focus, mood, and energy throughout the day. Reduce the Risk of Dehydration and Heat Stress Prolonged exposure to high indoor temperatures can increase the risk of dehydration, particularly for children, older adults, and those with existing health conditions. When your home stays cool, your body does not need to work as hard to regulate temperature. This helps reduce fluid loss and lowers the risk of heat exhaustion and heat stress during extreme weather. Fewer Insects and Parasites Indoors Warm, humid environments attract insects such as flies, mosquitoes, and cockroaches. These pests are not just annoying. They can also carry bacteria and parasites into your home. Keeping indoor temperatures controlled and humidity levels lower makes your home less inviting to insects, helping create a cleaner and healthier living space. Take Back Control of Your Comfort Modern cooling solutions allow you to manage indoor temperatures efficiently without relying on fans or open windows. This gives you consistent comfort throughout the day and night, even during heatwaves. With expert advice and tailored solutions from JSR Refrigeration & Air Conditioning, you can enjoy a cooler home, better sleep, and improved wellbeing all summer long.

Learn these few tips to help you save energy during Autumn. By Team JSR We all know there will be days during autumn where you’ll end up using both the heat pump and the air conditioner within 24 hours. Maintaining suitable temperature can become difficult and may start to increase your energy bill overtime. We’ve put together some few energy savings tips to help you save energy during Autumn. 1. Be wise when to open windows On cooler days in Autumn, open blinds and curtains to let the sunlight in and reduce energy usage for heating. Furthermore, on warmer days, open windows to let fresh cool breeze in the home. However, if your family member is allergic to pollen, don’t open the windows for ventilation in the morning hours as the pollen count is at its highest. It might be better to just run the air conditioner or a ventilation system machine than to deal with the family member’s allergy problems. 2. Cook outdoors, if possible Firing up the BBQ outdoors during a warm autumn afternoon is a perfect time to cook. Cooking outside will prevent you from using the stove or the oven indoors, as they can heat your home quickly. On cold days, use the kitchen. Furthermore, less heat in the house makes the HVAC unit to work less, saving you money from electricity bills. 3. Autumn Cleaning for Better Energy Efficiency When you’re doing seasonal cleaning, don’t forget to clean machinery that boosts energy efficiency in your home. For example, if you have a ceiling fan, clean the dust off it. Most importantly, clean the back of your refrigerator. Dust, dirt, dead insects, and pet hair can accumulate behind the fridge can reduce proper airflow through the coils, encouraging your refrigerator to work much harder to preserve your food and drinks in cold conditions. For average NZ households, refrigerators consume 10% of all energy. Cleaning behind the fridge will not only make the refrigerator operate more efficiently, but will make a big difference in your monthly electricity bill. 4. Get your HVAC Maintained Heating, ventilation, and air conditioning system should be serviced annually to work efficiently. Don’t wait to maintain the systems until winter arrives. Get HVAC maintenance during autumn, as you might be surprised that your HVAC isn’t working on the first day of winter. If you avoid these problems, you may end up paying thousands in repairs. All of this can be prevented from regular maintenance. JSR’s regular HVAC maintenance includes coil cleaning and testing the refrigerant charge to ensure your HVAC system is operating efficiently as possible. Regular maintenance will help your systems avoid breakdowns during winter, allowing your family to use HVAC systems safely.

Look After Your Ducts Autumn is a great season to get your ducts cleaned and sealed If you clean the ducts, energy efficiency will improve since the airflow won’t be blocked by dust and debris. Sealing ducts will also make the air conditioning’s airflow to not leak into the unconditional spaces of your home. Encouraging less energy wastage, home pressure balanced and reducing hot humid air pulled from tiny holes. 6. Upgrade to new HVAC systems for better energy efficiency If you are thinking about upgrading or purchasing a new HVAC system, Autumn is a perfect time to do so. HVAC specialist usually get busy during the peak of the summer and winter months. In fact, it’ll be easier to install your new HVAC system while autumn is comfortable for your home. To save more energy, always look out for the Energy Star rating that will help you maximise energy savings annually for any refrigerator, air conditioner, and Heat pumps systems.

And we’re not talking about retailers here! No, thieves and burglars positively love the holiday season because of the huge number of unguarded businesses and homes as people make the holiday exodus. So if you want to avoid some nasty surprises upon your return to work, then follow these tips to keep your business safe. Lock up your valuables You may have locked up the cashbox, but what about chequebooks and any invoices or printed materials with your bank account details that may be lying around the office? It’s surprising how many people overlook the obvious steps. And while you’re at it, put away out of sight all other valuable company property in a secure or lockable area. Watch out for any suspicious activity In the run-up to the holiday season keep an eye out for anyone loitering or hanging around the workplace and carpark. Burglars often survey a business before they strike so make sure you report any suspicious or unusual activity and behaviour to the police. Use technological solutions Most businesses will have a burglar alarm and security system already installed, but it might be worth considering an upgrade as the technology continues to rapidly advance. You may, for example, want to consider Wi-Fi enabled, motion detection cameras that you can keep a check on through a smartphone app. Night vision and two-way audio are additional layers of security you can implement. It’s well worth investigating the possibilities – often it’s not as expensive as you might have first thought and if you weigh up the expense of upgrading your security versus the costs of a break in, then often it’s a cost-effective solution. Be wary of fundraisers Christmas is an important time of year for charities wanting to do good during the festive season. It’s not uncommon, however, for thieves to pose as charity fundraisers in order to gain access to a workplace so they can evaluate entry points and get an idea of the layout of the office and where valuables are kept. So be cautious of any fundraisers that want to access the office beyond the reception area. Ask neighbours to keep a watchful eye Not all businesses shut down over the Christmas period and so it’s worth checking with neighbouring business owners to see if anyone is able to keep a watchful eye on things while you’re away. As a business owner, you work hard all year round and deserve some rest and relaxation over the holiday season. But if you want your Christmas to be memorable for all the right reasons, then use these tips to make sure that in your absence, your business is as secure as possible.

Whether you’re aiming to lower your heating expenses, enhance your comfort, or both, understanding how to optimise your heatpump unit is essential. In this guide, we outline the ideal temperature settings for heatpump in New Zealand households during winter and highlight key habits that can help you save money throughout the cooler months. Explore our 2024 Winter Heating Guide for more ideas on keeping yourself cosy. What Are The Recommended Winter Heat Pump Setting For NZ? Generally, it’s advisable to set your heatpump temperature between 18 and 20 degrees Celsius during winter. This range provides a good balance between comfort and energy efficiency for most areas in New Zealand.However, the ideal temperature for your home may vary based on several factors, such as your location, the level of insulation in your home, and your personal preferences and comfort levels. Does the Temperature of My AC Really Matter? Selecting the appropriate temperature settings for your heatpump is crucial for many reasons. The ideal temperature can: Improve comfort levels for everyone in the house Protect your health and enhance indoor air quality Increase the energy efficiency of your heatpump unit Reduce home costs, saving you money on your electricity bill What’s the Ideal Heatpump Temperature Setting For Winter? In the colder months in New Zealand, it’s advisable to set your heat pump to a range of 18-22 degrees Celsius. While this might seem low for keeping your home extra toasty in the winter, setting the unit to very high temperatures will consume much more energy and put unnecessary strain on your heat pump.If it’s cold enough that you want to run the heating all night, reduce the temperature to around 16-18 degrees. This will ensure you wake up cosy while keeping your heat pump usage cost-efficient. What is the Most Efficient Temperature to Set Your Heatpump To? While it might seem straightforward to use the heat setting on your heatpump during winter, there are other useful settings on your split system heatpump that can enhance efficiency and comfort. Besides heat mode, you can utilise dry mode, eco mode, sleep mode, and turbo mode. Though these modes differ slightly in energy consumption, opting for an energy-efficient heatpump model can lead to significant energy savings overall. Dry mode tends to be more energy efficient than heating and cooling modes, but keep in mind that it’s not as effective on very cold or very hot days. When to Use the Heatpump Dry Mode in Winter? Dry mode in your AC system reduces humidity levels in the room and is ideal for use when there’s a lot of moisture in the air. If you live in a region with mild, wet winters, dry mode can enhance comfort by removing excess moisture from the air and circulating clean, dry air back into the room. Tips for Maximising AC Energy Efficiency in Winter Maximising the energy efficiency of your heatpump in winter goes beyond just setting the right temperature. Factors like home insulation, heatpump condition, and household habits play crucial roles in optimising efficiency. Here are effective ways to enhance your heatpump’s energy efficiency: Insulate Your Home: Improve insulation to reduce heat loss. Seal Air Gaps: Close gaps around doors and windows to prevent heat leakage. Close Unused Room Doors: Focus heating efforts on occupied spaces. Upgrade to Double or Triple Glazed Windows: Enhance thermal insulation. Clean or Replace Air Filters: Maintain optimal airflow and efficiency. Regularly Service Your AC Unit: Ensure peak performance and longevity. By implementing these measures, you can significantly improve your heatpump’s efficiency during the winter months, reducing energy consumption and costs. Service Your Heatpump For Winter Regular maintenance for your heatpump system ensures year-round comfort, lowers energy costs, and extends its lifespan. It’s best to schedule a heatpump service for winter sets in to ensure your heating system is prepared to keep you warm during the coldest months.

The short answer is it’s usually too difficult. Not impossible — if you have enough social pressure, like an impending deadline and a boss breathing down your back, you can get things done even when you have very little energy. But what about the rest of the time? It’s so hard to focus and get important work done when you’re low on energy. And so, let’s look at some of the best ways to find the energy you need to get the important stuff done. 1. More sleep. This is obvious, but most people don’t get enough sleep, so it had to be said. If you’re tired all the time, it’s possible that you need more sleep. Shoot for 7-8 hours. Longer than 9 hours and you might actually feel more tired. If you have trouble falling asleep, turn off the computer, wind down by reading and flossing and washing up, then lay down, close your eyes, and start picturing your entire day (that just passed) in the smallest detail, from the moment you woke up. You will usually fall asleep within a few minutes. 2. Tea. If you have a lull in the afternoon, a break where you have some tea is usually the perfect solution. It’s partly because when you take a break you slow down, and partly because green tea has a bit of caffeine but not too much. 3. Exercise. You’ve heard it before, but exercise is one of the best ways to have more energy each day. Start the day with some exercise, sometime in the morning, and the rest of your day is always better. Even a brisk walk or jog is enough. 4. Naps. You got more sleep at night, but you’re still tired? Take a nap if at all possible. Usually, just 15-20 minutes will be enough to get you feeling more rested and ready to take on the world. 5. Music. Sometimes you just need your mood lifted. Play a few songs with a good beat, and it will get you moving more. 6. Water. Often we’re dehydrated and that makes us feel tired. Drink plenty of water, and you’ll feel better throughout the day. 7. Walk, stretch, refresh. Take frequent breaks. Working too long without breaks will drain you. Every 30 minutes or so, get up, stretch, walk around, get some water, and refresh your mind. You’ll be more focused because of the breaks. 8. Talk with someone. Get up and find someone to talk to. If there isn’t anyone, call someone. It often helps you to get your mind off your work, or get some perspective, or new ideas that will energise you. 9. Work with someone. It can be hard to sustain your motivation and energy levels if you work alone. Working with someone else on a project can give you that motivation, bring in fresh ideas and energy, and make the project more fun. 10. Find your body’s rhythm. It’s not possible to have high energy levels all day long — we all have a dip sometime. It’s a good idea to pay attention to your energy levels and do your most important work when you have the energy, and do more routine work (or rest) when you normally have a dip. Use the dip to schedule a nap or exercise or a tea break. 11. Play. Our minds need play to refresh themselves and find new sparks. So have something that you have fun playing, and take a break now and then to play it. Sudoku, solitaire, Words with Friends, Angry Birds, juggling, anything. 12. Take a shower. If possible, take a quick shower to refresh yourself. A hot shower can melt away tension, and a cold shower can wake you up. 13. Meditate. Even 5 minutes of meditation is great for finding mindfulness and focus. If you have time for 10-20 minutes, even better. Contact JSR Refrigeration and Air Conditioning Today!

By Team JSR • May 14, 2026 • 4 min read As temperatures drop across the Waikato, many households and businesses start to notice their power bills climbing. Heating is usually the biggest driver of winter energy use, which raises a common question: can a heat pump actually help reduce costs? The short answer is yes, but only when the system is correctly sized, installed, and maintained. How Heat Pumps Use Less Energy Heat pumps do not generate heat in the same way traditional electric heaters do. Instead, they transfer heat from the outside air into your home or building. This process uses significantly less electricity compared to resistance heating methods such as bar heaters or plug-in electric heaters. Because of this efficiency, heat pumps can deliver multiple units of heat for every unit of electricity used, making them one of the most cost-effective heating options available in New Zealand. Why Performance Matters Not all savings are guaranteed. A poorly installed or underperforming system can work harder than necessary, which reduces efficiency and increases running costs. Key factors that affect performance include: Correct system sizing for the space Proper installation and airflow design Regular filter cleaning and servicing Ensuring the outdoor unit is unobstructed Even small issues, such as dirty filters or restricted airflow, can have a noticeable impact on energy use over winter. The Role of Maintenance in Reducing Costs Autumn is one of the best times to service a heat pump before peak winter demand. A professional check helps ensure the system is running efficiently, identifying issues early and preventing unnecessary energy waste. Well-maintained systems typically: Heat spaces faster Run for shorter cycles Maintain more consistent indoor temperatures Use less electricity overall Heat Pumps vs Traditional Heating Compared to standard electric heaters, heat pumps are generally far more efficient. Over time, this difference can lead to meaningful savings, particularly in homes or businesses that require consistent heating throughout the day. They also provide an added benefit by offering cooling in summer, meaning one system can serve year-round comfort needs. Getting the Most From Your System To maximise savings this winter, it is important to use your heat pump correctly. This includes setting a stable temperature rather than frequently adjusting it, and avoiding extreme temperature settings that force the system to work harder. Final Thought A heat pump can absolutely reduce winter power bills, but the real value comes from choosing the right system and keeping it well maintained. JSR Refrigeration and Air Conditioning helps homes and businesses across Hamilton and the wider Waikato region improve heating efficiency, reduce energy costs, and stay comfortable through winter.

Hands down, the safest heating option for your home is a heat pump. Some heating sources have flames or hot surfaces to contend with. Obviously, these are not ideal when you have young children and pets around the house. They could easily burn themselves without realising it. Plus, open flames are always a danger around curtains, tissues, or other fabrics. However, a heat pump has none of that danger. With the unit situated high on the wall, well out of reach, there is no danger of your kids or pets accidentally bumping into it. Plus, your heat pump can even run safely when you aren’t home or while you are sleeping. The Dangers Of Other Heating Sources Some heating sources are downright dangerous. Here is a rundown on what to be mindful of: Portable Gas Heaters: These are the worst of the lot. Not only do they have an open flame and are hot to the touch, but they let off large levels of carbon monoxide. Breathing in high levels of the gas can cause carbon monoxide poisoning. Powered Heaters: Again, these are very hot to the touch. They are also very power-hungry, so are a danger to your power bill! On top of that, they can be a fire risk. For example, if you accidentally cover the vents of an oil fin heater (popular for draping clothes over, or if a curtain blows over the area), then it can spark a fire in your home. Fan Heaters: Again, these devices are hot to touch. Because they are small, it is tempting to pick them up to move them, running the risk of a burn. As the heater is powered by a fan, it has a habit of collecting dust on its blades. This can be a huge fire risk, as a build-up of dust can cause the unit to overload and spark. They can also be easily knocked over, causing another fire hazard. The Healthiest Heating Option We have just learned that some heating options are dangerous for your health. Especially unflued gas heaters. So, what is the healthiest heating option? Again, the heat pump wins hands down. New Zealand homes can be notoriously damp and cold. Damp homes are not healthy homes. Instead, they can be filled with mould, bacteria, and pollutants that are bad for your health. Fortunately, a heat pump can help to combat that. When you use your heat pump for heating, it can prevent condensation from forming on windows. It does this by circulating warm air around the room, just like demisting the windscreen in your car. Less condensation means less moisture and less chance for damp and mould. Are you in the Waikato and looking for a healthier and safer way of heating your home? Then get in touch with the team here at JSR. We are heat pump experts and can recommend the best option for your family. Give us a call today! Contact JSR Refrigeration and Air Conditioning Today!

FAQ Commercial Heat Pump FAQ Frequently asked questions regarding commercial VRF/VRV systems and HVAC maintenance. How does simultaneous heating and cooling 2-pipe VRF work? Simultaneous 2-pipe VRF systems (like Mitsubishi CITY MULTI R2) use a BC controller that routes refrigerant gas and liquid dynamically. Heat rejected from cooling zones (such as server rooms or sunny north offices) is redirected to warm up heating zones, capturing waste energy for extreme efficiency. What are the advantages of VRF over traditional ducted split systems? VRF systems allow individual temperature control in dozens of separate rooms using one outdoor unit loop. Inverter compressors adjust output precisely to match current load, preventing energy wastage common in single-zone ducted systems. When should a business choose a water-sourced VRF system? Water-sourced VRF is ideal for multi-story towers with existing cooling water loops, coastal buildings exposed to salt air, or regions with severe sub-zero winter temperatures where air-cooled defrost cycles cause heating interruptions.

With ongoing technological advancements, the horizon of air conditioning is filled with promising innovations and trends set to transform our cooling experiences. A noteworthy aspect of this forthcoming era is the seamless integration of air-to-water heat pump systems into traditional air conditioning setups. Join us as we delve into the pivotal advantages and considerations that position air source heat pumps as a substantial trend in the future landscape of air conditioning. Energy Efficiency Famous for their outstanding energy efficiency, air source heat pumps stand out in comparison to conventional air conditioning systems. While traditional systems depend on electricity to cool the air, modern heat pumps harness the existing heat energy in the surrounding air. Through the transfer of heat rather than its generation, these systems achieve remarkable energy preservation. Recognised to be up to three times more efficient than standard heating and cooling setups, air source heat pumps not only bring substantial cost savings but also contribute to a diminished environmental footprint. Dual Heating and Cooling A stand-out characteristic of air source heat pumps is their capacity to offer both heating and cooling functionalities. In contrast to traditional air conditioners that singularly concentrate on cooling, heat pumps can seamlessly reverse their operation to emit warm air in colder seasons. This dual functionality positions heat pumps as comprehensive solutions for year-round comfort, negating the necessity for separate heating and cooling systems. Additionally, air source heat pumps utilize the ambient air as a renewable energy source. Given the availability of air, the heat pump consistently extracts heat, ensuring efficient cooling or heating. This reliance on renewable energy not only diminishes the carbon footprint, but also aligns with sustainability objectives. Environmental Advantages In comparison to conventional air conditioning systems, air source heat pumps exhibit a considerably reduced environmental footprint. Harnessing heat energy from the air, these systems diminish the reliance on burning fossil fuels for heating or cooling, consequently minimising greenhouse gas emissions. Adopting this eco-conscious approach is imperative for cultivating a sustainable future in New Zealand. Advanced Technology Technological progress has significantly elevated the performance and efficiency of air source heat pumps. Breakthroughs like variable-speed compressors, cutting-edge refrigerants, and intelligent controls have heightened the efficiency, reliability, and user-friendliness of heat pumps. The incorporation of variable-speed compressors enables the system to dynamically adapt its operations according to the cooling or heating requirements, guaranteeing optimal energy usage and comfort. Historically, air source heat pumps faced a challenge in performing effectively in colder climates. Nevertheless, contemporary manufacturers of air-to-water heat pumps have successfully addressed this limitation through enhanced designs and advanced features. Specifically engineered for cold climates, these heat pumps operate efficiently even in sub-zero temperatures, rendering them well-suited for regions characterised by harsh NZ winter conditions. The New Zealand government are recognising the importance of energy efficiency and sustainable housing solutions. EECA (Energy Efficiency and Conservation Authority) are encouraging kiwis to adopt sustainable energy solutions systems by granting a cover-up to 90% of the cost to purchase and install insulation and an efficient heater or heat pump for your home. Helping you with energy efficiency and reducing the cost of your power bill. To see if you’re eligible for warmer kiwi homes, check out EECA.

Nonetheless, myths and misinterpretation about their usage continue to persist. These myths cover various aspects, including power consumption, operating costs, maintenance, and what they can and can’t do. To clarify any misconceptions, we’ve addressed five common myths about heat pumps below. Myth #1: Heat Pumps Are Expensive to Operate This is one of the most common misconceptions, but commonly misunderstood. Modern heat pumps achieve 300-400% efficiency, meaning that for every 1kW of power consumed, they can produce 3-4kW of heating or cooling. The higher the efficiency of an appliance, the lower its operating costs. According to the Energy Efficiency and Conservation Authority (ECCA) Electric Homes Technical Report 2024, heat pumps are the most efficient way to use electricity for heating your home. In New Zealand, the benefits of electric heat pumps (or reverse cycle air-conditioners) are well known. Heat pumps can deliver 3-4 times more heating for the same energy input as gas heaters. While most home heating options have a performance efficiency below 100%—with electric resistance at nearly 100%, gas at about 80%, and wood fires around 65%—heat pumps average around 350%, with some performing even better depending on the region and temperature. Heat pump water heaters, though less common, offer similar efficiency advantages. Another example of the graph below illustrating the cost comparison of a heat pump with space heating. Image source: Ellison, J., Thorn, D., Pawson, M., & Griffith, D. (2024). Electric Homes Technical Report. Retrieved from https://www.eeca.govt.nz/assets/Uploads/Electric-Homes-Technical-Report_March-2024.pdf Myth #2: Heat Pumps Require High Maintenance Split system heat pumps need minimal maintenance beyond regular filter cleaning. We suggest cleaning the filters at the start of each season to keep them effective at removing allergens like pollen and dust, as well as neutralizing bacteria and viruses. For frequent users, it is recommended to have a professional check-up from a heat pump specialist to ensure the best performance. Heat pumps also feature a self-cleaning mode that dries internal components, helping to prevent mould and keep clean, odour-free air. Myth #3: Heat Pumps Are Noisy While the noise level of heat pumps can vary depending on factors like model, size, and fan speed, they are generally very quiet. Thanks to ongoing advancements in technology and design, modern heat pumps are engineered for noise reduction and improved energy efficiency. Most new heat pumps come equipped with a “quiet mode” feature, designed to minimize noise levels during operation. This mode reduces the fan speed and optimises the compressor’s performance to ensure the heat pump runs as quietly as possible, making it ideal for nighttime use or maintaining a peaceful environment in your home. This innovation reflects the latest advancements in heat pump technology, prioritizing both comfort and tranquillity. Myth #4: Setting the Temperature Higher or Lower Heats or Cools Your Home Faster Although it might seem logical, adjusting the temperature higher or lower won’t speed up heating or cooling. Your heat pump will work at the same rate, regardless of the set temperature. The best approach is to set it to a comfortable level and let the system do its job. If you need quicker results, Mitsubishi Heavy Industries split systems offer a High Power Mode, which provides 15 minutes of boosted airflow to rapidly heat or cool your space—ideal for when you first arrive home or wake up. Ideally, Daikin split systems also offer a similar mode known as Powerful Mode, offering quick boost or reduction in temperature where needed. Myth #5: Heat Pumps Are Bad for the Environment Heat pumps are environmentally friendly due to their high energy efficiency—up to 400%. This means they use far less electricity than other heating and cooling options, reducing their environmental impact. Additionally, most modern split systems now use R32 refrigerant, which has a much lower Global Warming Potential (GWP) than older refrigerants, further helping the environment. R-32 is a well-balanced refrigerant that has gained significant attention due to its efficiency. By transferring heat more effectively, R-32 can reduce electricity consumption by up to 10% compared to air conditioners that use R-22. Additionally, R-32 has a global warming potential (GWP) that is one-third lower than commonly used refrigerants like R-22 and R-410A, making it a more environmentally friendly option. Unlike wood burners, heat pumps don’t produce harmful micro-particles, making them better for both the environment and your health. Contact JSR Refrigeration and Air Conditioning Today!

By Team JSR • 2023-02-07 • 4 min read AC Running Endlessly: How to solve it By Team JSR After a tiring day from work, the feeling of entering an air-conditioned house cannot be matched. It is especially comforting when the weather is extremely warm and humid. In some cases, you may find your air conditioner (AC) running more often than necessary, or it could be struggling to work. Issues like these could indicate that something is wrong, and you should consider having it serviced. In this article, we’ll go into detail on the causes of a heat pump running continuously, and provide solutions to solve it. Many of these issues can be resolved easily through regular maintenance. When all else fails, a professional’s help might be required. Should you run AC continuously? Generally, an air conditioning unit operates in recurring cycles under normal conditions. The cycle of heating and cooling continues until it reaches your desired temperature when you turn it on. If you have inverter AC model, they are energy efficient and cost-effective as they are designed to run at a lower power consumption. The way inverter works is by controlling the compressor’s speed to keep the temperature steady and allowing you to run fewer cycles, reducing your energy consumption. When the difference between the outdoor and indoor temperature is larger, it’s natural for your heat pump to cycle more often or for longer duration. This is because the AC has to run more frequently and with more effort in order to keep up with the desired temperature. Setting the temperature to economical is often the key to making an air conditioner run smoothly again. In another scenario, if your AC unit is running cycles more often than necessary, it’s likely due to an open door or window that’s allowing the conditioned air to quickly escape. To fix this issue, check for any open spaces that could be letting the air out and close them. Doing so should help your heat pump cycle less frequently and save you energy in the process. If your AC runs constantly despite the mild weather or keeps running no matter what, you might need to look into the root of the problem. Why should you be concerned if the AC runs constantly? Ignoring an AC issues can create serious problems in the long run. It’s always best to take care of these issues as soon as possible. Here are some issues that can arise: Your AC losing its effectiveness – AC units are meant to make our homes more comfortable and enjoyable. However, when they start malfunctioning, they become unreliable and unable to carry out their primary role effectively. Fast energy consumption – The more AC cycles, the higher amount of energy it consumes. Thankfully, modern AC models are designed to be more energy efficient than their older counterparts, allowing you to save on electricity bills. For maximum efficiency, AC must be maintained annually. Malfunctioning AC parts – It may seem inconvenient to service your AC, but not resolving the problems can cause even more damage and significantly decrease the lifespan of it. What causes AC to keep cycling constantly? Common issues for constant AC running: Clogged air filters – The AC’s filters have an essential role to keep dust and particles away, improving indoor air quality, and letting clean air flow through. The issue is that they can get clogged when they have too much debris or dirt trapped, and airflow becomes much more restricted, meaning your AC has to work harder and longer to reach desired temperatures. Dirty evaporator coil – The evaporator coil absorbs heat from the air that is blown onto it. Because of this, it is susceptible to dust build-up; and over time, it can become an issue, as the coil gets covered in particles, reducing the AC’s ability to cool, and causing it to consume more energy. You may even notice the AC blows warm air instead of cool air. This can also happen if the evaporator coil is frozen. Clogged or leaky vents – Clogged or leaky vents. Vents and ducts enable air to flow and allow the AC to run as it is designed to. When there are obstructions or leaks in the vents, air may not flow correctly, or it may even leak, preventing the AC from working properly. Thermostat issues – The thermostat gives readings of the temperature, and thanks to it, the AC can stop the cycle when the temperature is adequate. In some cases, it is possible that the thermostat stops working correctly, and gives incorrect readings, thus not allowing the AC to stop the cycle even if the room has been cooled off. Low refrigerant level – An AC’s refrigerant level can become low when there is a leak. The refrigerant is what enables the AC to cool warm air off, so if there is not enough, even when the AC runs constantly, it won’t get to the desired temperature. Incorrect AC size – The AC’s size should be suitable for the room’s size and features. An AC that is too small may run constantly to cool a room that is too big for its capacity. And an AC that is too large is no good either, as it can waste more energy to cool a small space. What if the outdoor AC unit is running continuously? It may happen that it’s not the indoor unit that keeps cycling, but rather the issue is that the outdoor unit keeps running. It can be more difficult to notice malfunctions in the outdoor unit, as we look less at it, and thus do not think much about it. But some of the symptoms of an outdoor unit running constantly are also noticeable in the way your AC cools. It may not cool entirely, or you may notice it is not as effective as it used to be, or there is a sudden increase in its energy consumption. Dirty condenser coil. In some cases, you may notice the outdoor unit keeps running even if the temperature indoors is adequate. This can happen when there is dust build-up on the condenser coil. The condenser coil releases the heat that is absorbed from your home’s air. As it is in the outdoor unit, it is more susceptible to external factors. Not only dust and particles, but rainwater, frost, and insects can also get in between the outdoor unit’s components. Dust and dirt covering the condenser coil prevent it from letting the heat disperse, and thus the outdoor unit keeps running. What can be done to fix AC from running constantly? Many of the causes listed above are easily prevented by maintenance checkups. The aim of preventive maintenance is to keep the AC functioning smoothly for as long as possible. It reduces the need for repairs and replacement of components that could have been saved if serviced sooner. These are some of the routine maintenance tasks that prevent issues down the road. Filter maintenance and cleaning. Fortunately, this task can be easily done by yourself, if you closely follow the appropriate directions. Keeping the air filters clean will not only let the AC run better, but you will also notice improved indoor air quality. Routine cleaning and checkup. You can perform a basic checkup by cleaning the outer casing of the AC unit with a damp cloth to remove dust. And look for any obstructions around the vents, leakage or unusual noises or smells. Remember to do this both for the indoor unit and outdoor unit. AC unit maintenance. This is a task a professional should perform, as they will not only solve any issues that need immediate attention, such as cleaning the dirty condenser and evaporator coils, but also find any irregularities that could be overlooked if not observed with expertise. Duct maintenance. Usually, if the AC’s installation is properly made, the system’s ductwork will remain optimal for years, as filters keep particles and debris out. Most of the time, the only maintenance ducts need is a checkup to see everything is in order and some occasional cleaning.  But sometimes, ducts can present leaks that need to be caulked, or they may need to be insulated if extreme weather conditions affect them. In any case, an expert’s advice is needed for ductwork maintenance. When should you contact a professional? If regular maintenance fails to resolve any errors with your heat pump, you might need to consider contacting a certified technician for further assistance. An AC repair expert might be the only solution if your thermostat or refrigerant is not working as it should. They can efficiently fix the issue and provide useful advice regarding further steps you can take. The emphasis on hiring an experienced professional for the installation of an air conditioning system is important. Doing this will ensure that you get the maximum benefit from your HVAC system. A qualified AC technician company like the JSR will make an efficient and reliable installation, helping you save money in the long run. They have the experience required to ensure the installation is optimal for your home’s needs, which could lead to money-saving benefits. For example, an AC fitted in your home might be an incorrect size; the technician can recommend replacing it. This situation would have been avoided with the advice of a credible professional, who considers your home’s size, ceiling height, sun direction, insulation, and other suggestions, to recommend the appropriate AC with the correct capacity.

By Team JSR • 2023-04-12 • 4 min read How Important Is Air Conditioning In A Warehouse? By Team JSR – Source Warehouses are one of the key links in a business’s supply chain, allowing for easier storage, managing and distribution of stock. The need for warehouse climatisation may commonly be undermined, especially when there is no special need for refrigeration of perishable goods. However, the reality is that many non-refrigerated products have temperature requirements for storage to assure quality. Also, the health and comfort of workers should always be a priority, especially in a setting where more physically demanding tasks are performed. In this way, the role of heating, ventilation and air conditioning (HVAC) in warehouses becomes paramount. Climate control in warehouses is thought to be very costly and power consuming, which can be true to some extent, but there are some strategies that can increase the efficiency of the HVAC system, which we will touch upon later. Also, it is important to note that investing in an effective HVAC system helps cut down cost from deterioration of products due to inadequate storage conditions. Of course, the climatisation needs in a warehouse are not the same as those in an office setting, and storage buildings tend to have their own challenges and characteristics, so general climate control recommendations do not always apply in these situations. As many other large buildings, warehouse pose challenges for heating and cooling, these are the specific characteristics that make them different to other commercial spaces: Large spaces with high ceilings. Warehouses tend to be very large spaces with tall ceilings. Vertical space serves the purpose of optimising storage by fully occupying the area without requiring extra square meters. Open spaces with little to no divisions/separation. Walls and separations make it easier to cool and heat certain areas, but storage buildings tend to consist of large open spaces, with few (if at all) divided areas. Entrances are usually open for receiving and dispatching goods. Efficient heating and cooling always calls for keeping the air-conditioned area closed to prevent treated air from escaping, but in warehouses this is a great challenge. Need for special equipment for perishable products. Refrigeration rooms and equipment need a cool environment to function and keep the ideal temperature of the products. But at the same time, they create higher heat emissions that can negatively affect climate control. Poor insulation due to construction materials. The high demand for storage facilities calls for quick and economical infrastructures; due to this reason, the use of metal and other low insulating materials is widespread. As mentioned earlier, comfort and health of workers should be decisive for prioritizing the implementation of an air conditioning system. Many of the aspects specified for workplaces by ASHRAE are applicable for warehouse workers. The difference being in this case, to pay more attention to specific requirements for physical tasks, rather than office work. Indoor air quality (IAQ). This term refers to the quality of elements in the environment and air we breathe inside buildings. Poor IAQ is a serious risk to the health of a building’s workers and visitors. The presence of air pollutants, such as volatile organic compounds (VOCs) and allergens, lower the IAQ. Many VOCs are gasses emitted from chemicals used in industrial solvents, paints, and dry cleaning products. Another way IAQ can be lowered is through an increase in carbon dioxide concentration and low oxygen due to high occupancy and activity in the warehouse. One of the aims of an HVAC system is to improve IAQ through ventilation and humidity control. Some warehouses may have natural ventilation, as they have an open entrance for shipments, this can help keep air flowing and reduce the concentration of harmful gasses. Over time, with prolonged exposure to poor IAQ, health issues can arise. One of the main concerns for commercial buildings is related to Sick Building Syndrome (SBS), and its symptoms vary from headaches and lack of concentration, to cough, nausea, and increased allergy and asthma flare-ups. In the workplace, to have good IAQ means to protect the health and safety of workers. Temperature related complaints and thermal comfort for workers. Heat related accidents are a great concern in physically demanding jobs. Fatigue, heat stroke and dehydration are some of the risks associated with working at high temperatures. The lack of thermal comfort can decrease focus and concentration of office workers, resulting in dips in productivity; and the effects it has on warehouse workers are just as negative. Implementing an effective air conditioning system, especially in older infrastructures, can result in great benefits, both for the comfort of workers and productivity. OSHA establishes some guidelines to determine whether thermal stress is too high to perform certain tasks. They take into account workload, clothing and temperature to estimate if it is too hot to complete the job without risk of injury. As an example, for strenuous workload, such as movement at a high pace, climbing stairs, or heavy lifting, the temperature limit is at 25ºC (77ºF) for an average sized worker. This means that strenuous work above this threshold is unsafe and not advisable. It is important to take into account all other factors, such as the physical condition of the worker, weight, clothing, and whether the worker is acclimatized to the job or not (OSHA establishes a period of 2 weeks for this). Ventilation and how it helps improve IAQ We have discussed IAQ above and mentioned that ventilation and humidity control can improve it.  Through mechanical ventilation, we can control the amount or fresh air that is introduced indoors and treat it before it is breathed by workers, which is extremely important in spaces where natural ventilation is limited or not possible. The standard for ventilation is expressed as the amount of air that should be introduced per minute (expressed as CFM), and according to ASHRAE, the minimum ventilation rate for warehouses is 0.06 CFM per square foot per person. This means that the larger the building and the more occupants, the more fresh air it needs. The CFM figure helps us find out the airflow needed according to the building’s size and workers. For example, for a 7000 square feet and 30 feet tall warehouse, the result would be 420 CFM per person. Another metric to take into account is the air changes per hour (ACH) requirement, which is calculated through a formula that converts the minutes from CFM to hours. In our case, 420 CFM with an occupancy of 100 people would be equivalent to 12 ACH. This formula can easily be adjusted using the calculator in the link above. The lack of proper ventilation can be hazardous to workers. Without it, airborne particles remain in the same environment. With ventilation, contaminants get diluted and significantly reduce any threat to health. Also, in the case of bacteria and viruses, chances of contagion also decrease through correct ventilation. After becoming familiar with the requirements for warehouse HVAC, we can also apply some tips to improve the effectivity of the air conditioning system: Optimizing insulation. Even with construction materials that transfer heat (such as metal), there are strategies to improve their insulation. There are many industry standard guides for insulation materials; in general, fiberglass is considered a good insulation material for metal buildings. Another strategy is to keep the product reception and dispatching area separate from the storage area, to prevent cooled or heated air from escaping. This can be achieved through a double entrance, and automatic sliding doors may also be useful in reducing heat transfer. Ceiling fans for airflow. Industrial settings can benefit from ceiling fans to ventilate in-between air exchanges. Airflow increases the sense of comfort without the need to lower the temperature, and ceiling fans help even out the temperature as hot air rises. Zoning. A zoned air conditioning system consists of dividing a space into various areas or zones, and providing them with their own temperature control. This way, they can be individually cooled or heated accordingly, reducing hot and cold spots. This allows for more even temperature throughout the warehouse, while taking into account each zone’s features and cooling or heating needs. System’s energy efficiency. We have touched on a few points on energy saving, but there are even more ways to make the warehouse’s HVAC system more efficient. Looking into AC systems that allow better control of its temperature functions can be key in energy efficiency. For example, functions that allow to reduce the AC activity in low occupancy areas, or heat recovery systems that recycle exhaust heat from cooling one area to heat another area. Depending on the space that requires conditioning, Hitachi offers a wide range of HVAC solutions to fit all project needs. For warehouse offices and meeting rooms, where there is continuous occupancy for long periods of time, the Hitachi range of VRF and Commercial systems are highly suitable, especially Heat Recovery type VRF that allows for simultaneous heating and cooling. You can read more about the benefits of Heat Recovery VRF, here. When considering whole buildings, including warehouse storage spaces, larger HVAC systems are required, and large Commercial units or Chillers alongside VRF are ideal, especially if an air handling unit can be integrated into the system. Within the ranges offered, there are specialized systems to match the needs of all sized projects. If Hitachi VRF systems are the ideal choice for your project, you can enhance their operation with the use of airCloud Pro, letting you monitor and control multiple and entire Hitachi VRF systems from one access point, anytime. It gives you visibility of operational status, troubleshooting, scheduling and cleaning reminders, and more.

The latter is an element that sometimes gets overlooked in households. Humidity deeply affects our feeling of temperature, as higher humidity levels can make the environment feel stuffy and uncomfortable, while low humidity enhances cooling. There is of course an ideal range that reduces the impact of humidity on comfort. In this article we will be focusing on humidity, for comfort and health, its impact, and ways to manage it to suit household needs. When we talk about humidity, we are referring to the presence of water vapour, or moisture, in the air. Water evaporates from any source of water when heated, whether it is from directly boiling a pot of water in the kitchen, or from hanging wet laundry indoors, and the surrounding air then holds it. Warm air can actually hold more moisture than cool air; so to measure humidity in a practical way, we use the term relative humidity (RH), which is the water vapour concentration in the air in relation to the temperature. Relative humidity is expressed as a percentage; for example, 50% RH means that half of the volume of air consists of water vapour. To measure relative humidity indoors, a hygrometer or a humidity monitor is used. They provide humidity readings for the room where they are installed. It’s recommended to install them away from known humidity sources, windows, heaters, etc, because their accuracy can be affected by surrounding factors. What is the ideal range of humidity indoors? According to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), indoor relative humidity should be kept below 65%, to prevent mould growth, and to maintain comfort. Their guidelines do not specify a minimum value, but they advise monitoring any comfort related issues, such as skin or eyes dryness, nasal or throat irritation, which indicate humidity is too low. The Occupational Safety and Health Administration (OSHA) recommends a relative humidity minimum of 30% and maximum of 60%, which ensures comfort for most people in the office setting, although this can be applied to other indoor spaces, such as homes. The Environmental Protection Agency (EPA) comments that, ideally, relative humidity indoors should be kept below 50% whenever possible, to discourage pests attracted to moisture. The minimum they recommend is 30% RH. As relative humidity takes into account temperature, these general recommendations can be applicable all year round. However, for more accurate values, optimum relative humidity during summer is around 40%-50%, and during winter between 30%-40%. Most people feel comfortable in these ranges, but individual preferences may be different, so it is a case of finding the range that suits you best. Now that we have a better idea of what the ideal humidity level is, let’s take a look at the effects of relative humidity when it is too high and when it is too low. We consider that humidity is too high when it is over 80%, and too low when it is below 20%, at these values the negative effects of unsuitable humidity levels are more pronounced. Both situations pose some health-related issues, but there are also some symptoms that can be observed in our homes and furniture. What happens when there is too much humidity? When a space has too much humidity, it can easily manifest in the form of mould or mildew growth. Dark spots may start appearing in ceilings, wall paint can start to bubble up or chip off, wood furniture can start to show moisture stains or, worse, rot. Condensation and rust around electrical components and appliances is also caused by an excess of humidity. It can cause electrical malfunctions, raising the risk of short circuits and fire. Excessive moisture also attracts pests, such as insects, rodents and mites that need water to survive. The effects of high humidity on our health are just as serious: respiratory infections, worsened allergies due to the presence of mould or mites, more frequent asthma flare-ups, respiratory tract irritation, etc. What happens when there is too little humidity? When humidity is too low, the effects can be seen on wood flooring and furniture, which may start creaking, showing cracks or discolouration. Wallpapers start peeling off, while wall art, books and photographs can also suffer chipping, discolouration or become brittle. With low humidity, there is also more static electricity, which can damage appliances and exposed cables, increasing its risk as a potential electrical and fire hazard. Health wise, low humidity can cause respiratory irritation and infection, sore throats, eye dryness, nosebleeds, dehydration, eczema flare-ups, and skin irritation, which can show up like dry skin or chapped lips.

The effects of high humidity on our health are just as serious: respiratory infections, worsened allergies due to the presence of mould or mites, more frequent asthma flare-ups, respiratory tract irritation, etc. What happens when there is too little humidity? When humidity is too low, the effects can be seen on wood flooring and furniture, which may start creaking, showing cracks or discolouration. Wallpapers start peeling off, while wall art, books and photographs can also suffer chipping, discolouration or become brittle.

The presence of mould or mildew lowers our home’s IAQ, causing respiratory issues and allergies. High humidity is the main culprit for bacterial or mould growth. To keep them at bay, it is important to monitor humidity and keep RH below 65%, as per ASHRAE’s guidelines, or below 50%, the recommendation of EPA. With existing mould or mildew issues, you may need to inspect what the source of humidity in the affected room or area is, then look at your options to improve it or get rid of the root cause. In the case of existing dust or seasonal allergies, humidity can also play a role in aggravating these. When humidity is very low, allergens and particles easily flake off and can stay longer floating in the air, instead of settling down on flat surfaces. Because of this, many allergy sufferers can find their symptoms worsen in low humidity conditions. On the other hand, too much humidity can also be detrimental for people with allergies. Even though humidity makes particles and allergens clump up and remain on flooring and other surfaces, very humid environments are ideal for mites and other allergen carrying insects. So, there can be a higher presence of allergens in high humidity spaces. The key is to keep RH at a level that does not invite mites, mould spores and other allergens, and at the same time keeps dust particles away from the air. This balance is achieved between 40% and 50% RH, according to the Clinical Research Centre. According to the Sleep Foundation, high humidity increases wakefulness, reducing the time of crucial sleep stages when recovery and memory consolidation happen. Low humidity does not seem to have any direct impact on sleep, but the health issues we listed above can make it more difficult to get a comfortable sleep. They indicate that the ideal range of humidity for sleep is around 40% to 60%. However, there are many other factors that affect the quality of our sleep, check our article on improving your sleep with environmental adjustments for more information and tips. As we mentioned earlier, any body of water in our homes can evaporate and become water vapour, adding up to the humidity levels. Aside from that, what are other household sources of humidity? Let’s take a look at some of the most common ones: Cooking without ventilation. Even if you are not boiling a pot of water, any type of cooking (baking, frying, microwaving, etc.) produces steam and humidity, along with other fumes. This is why it is so important to have exhaust fans or an overhead range hood or extractor hood in the kitchen. Hot showers and baths. Steamy hot showers can feel comforting and relaxing on a winter day, but they produce a lot of steam that gets into every crevice, condensing especially near corners and other hard to reach places. Turning the exhaust fan on or opening a window to let the water vapour escape is helpful, but you will need to pay special attention to those nooks and crannies while cleaning the bathroom area, to prevent any chance of mould growth. Leaky taps and pipelines. Mould and water damage around sinks is not uncommon, but it can be prevented. Periodically checking the sealing of water pipelines, such as around sinks and wash basins, and maintaining taps will avoid humidity issues. Hanging laundry indoors. Some homes do not have balconies or exterior spaces to hang wet laundry, and hanging it indoors may become the easy solution, however it can cause excess humidity. If there is no other viable alternative, such as a tumble dryer, wet laundry indoors is best hung in a room that can be closed off from the rest of the house and either with a window or exhaust fan turned on to get rid of moisture. Appliances malfunctioning. Some appliances, such as refrigerators, dishwashers, washing machines and air conditioners, if not maintained properly can have issues with excess moisture or water leakage. Schedule regular revisions to prevent any malfunctioning to keep them running as efficiently as possible, and don’t delay any repairs or servicing. To lower or increase humidity, a humidifier and a dehumidifier can be used to adjust humidity, and are very useful for extremely dry or extremely humid environments, or situations where accurate humidity control is needed. However, many households need minor humidity adjustments that can be done naturally. How to lower humidity naturally: Encourage natural ventilation through windows and doors. Remove rugs and other unnecessary decorative textiles. Hang laundry outdoors or use a tumble dryer. Let more sunlight in. Get humidity-absorbing plants: such as English ivy, peace lily, Boston fern, to name but a few. Place a box or bowl of baking soda or rock salt near windows in humid rooms. How to increase humidity naturally: Boil more water. Take hot showers with the door open. Place bowls or pans of water around the room. Introduce indoor plants(watering and misting keeps them healthy and adds moisture to the air). Dry your clothes indoors. Get decorative and install a small indoor fountain. JSR recommends installing Hitachi cooling system in your home. They not only provide comfort by adjusting the temperature to your liking, they also treat the air by removing excess moisture and filtering allergens and other particles. In every Hitachi air conditioning, especially for residential models, the Dry Mode is ideal to quickly remove excess humidity from your space by just pressing a button.

While it might seem like a big job, taking proactive steps now ensures your heating system is in top condition before winter arrives. Why Autumn HVAC Maintenance Matters Regular maintenance keeps your HVAC system running efficiently, prevents costly repairs, and improves its overall performance. Key tasks include shutting down your air conditioning after summer, booking a professional check-up, sealing drafts, replacing air filters, and ensuring proper airflow. Scheduling a visit from an HVAC technician can also help identify and fix potential heating issues before they turn into major problems. These steps will help reduce energy waste, boost efficiency, and keep your energy bills under control during winter. 1. Book a Professional HVAC Check-Up Routine maintenance is essential for keeping your heating system in peak condition. Just as air conditioning units need a tune-up in spring, your heating system should be serviced in autumn. A professional check-up improves efficiency and ensures your system delivers consistent warmth throughout winter. Key Tasks Performed By HVAC Technicians: Lubricating motor bearings Tightening electrical connections Inspecting the heat exchanger Testing the thermostat Cleaning internal components to prevent dirt buildup Cleaning coils for optimal heat exchange Regular maintenance also helps detect and resolve potential issues before they become costly breakdowns. JSR offers maintenance plans that include scheduled tune-ups, priority service, and discounts on repairs, making it easier to keep your system in top shape. 2. Fix Any Issues Before Winter> If your furnace, heat pump, or boiler had any problems last winter, now’s the time to get them sorted. Common issues include strange noises, uneven heating, or a system that struggles to maintain the right temperature. Addressing these early can prevent emergency breakdowns during the busy winter months. 3. Replace Air Filters After Summer After heavy use over summer, HVAC filters can become clogged with dust and debris, reducing efficiency and airflow. Replacing them in autumn ensures proper circulation, helping your heating system run efficiently and improving indoor air quality. 4. Check Your Carbon Monoxide Detectors If you use a gas furnace or boiler, carbon monoxide detectors are a must for home safety. Test your detectors in autumn by changing the batteries and checking the alarms. Replace any units older than ten years to ensure reliable protection against carbon monoxide leaks. 5. Clean the Outdoor Unit Whether you’re shutting down your air conditioning system or preparing a heat pump for winter, the outdoor unit needs some attention. Keep it clean and free of debris to maintain efficient airflow and prevent damage. Outdoor Cleaning Tips: Remove debris like leaves, grass clippings, and mulch from around the unit. Trim back plants and shrubs to ensure proper airflow. Clear away dead tree limbs that could fall and damage the unit. Store patio furniture and outdoor items away from the HVAC unit. While outdoor air conditioning units are built to handle harsh weather, some homeowners choose to cover them for extra protection. If you decide to use a cover, make sure it allows ventilation and remove it before using the unit again in spring. Checking for airflow obstructions inside your home can improve HVAC efficiency and prevent unnecessary strain on your system. Indoor Airflow Tips: Ensure that all vents and registers are fully open and free from any blockages. Clean dusty or dirty vent covers. Inspect ductwork for damage or leaks and consider professional sealing to prevent heat loss. Get Your HVAC System Winter-ReadyBy following these maintenance tips, you can ensure your heating system runs efficiently all winter long.

But once the NZ summer cranks up, you’ll be obliged to crank up the AC even more. Learning about how you can save costs with your air conditioner while yielding its benefit is valuable knowledge to have that’ll last throughout summer. While you may search online for cooling system hacks, they are inexpensive and effective methods to help you cool your home easier. Some hacks encourage you to close vents or moving furniture around the home also helps with cooling. To help you become a cooling expert this summer, we’ve huddled 11 quick tips for running your AC in the most cost-effective ways possible. 1.  Avoid Thermostat Temperature Confusion As the reception of central air units has proven, a big downside to how smart thermostats generally are is that they cannot apprehend the cause of the heat. They just know it’s hot and may display inaccurate temperatures of your home. To fix this, move away the electronic items that get warm like the lamps or TVs away from the air conditioner or the thermostat. These items can make the room warmer than it actually is. 2. Cover your AC unit from Sun If your outdoor AC is exposed to the sun (which it shouldn’t), it might be in a risk of overheating and may not run as efficiently as it normally would. Overheated AC is less efficient and will work much effectively if it’s cooled by shading or protection from the sun. Make sure it has a good cover. 3. Clean Air Filters Dirty AC air filters can make your system run overtime. Replacing and cleaning it regularly helps make sure your system is running smoothly and without problems; saving you costs in the long-run. 4. Abstain From Heat Generating Tasks Cooking and baking are the main source for generating the most heat in your home. Although, other home activities also generate excessive heat, like the dishwasher or ironing clothes. Try to reduce these tasks until the temperatures cools off at evening time. 5. Set Thermostat Once and Ignore It To cool down a room economically, set the temperature to your liking and ignore it. Although it will take time to cool off, your home will maintain a comfortable temperature. 6. Check Your Indoor Humidity Levels Many people consider that a HVAC unit alone will cover all the heating & cooling solutions in your home. However, this is not true. Your unit cannot cover everything by itself. Humidity levels, for example, plays a critical role in providing comfort, especially in summer. If you have a dehumidifier, use it to reduce the amount of moisture in the air while eliminating potential allergens like mould and mildew. You’ll be surprised how much moisture there was in your home when the dehumidifier produces litres of water. 7. Get yearly maintenance for your AC A properly maintained unit will ease your energy bill throughout the summer and the year. The easiest way your AC system can operate inefficiently is by letting the cool air escape from your household. Your local Hamilton AC technician can inspect your insulation, leaks and tear of your AC system to ensure it’s not causing any problems, thus lowering the energy bill annually. Get in touch JSR heat pump & AC specialists. 8. Observe Your Ducts Ducts can often get clogged and dirty, resulting in a decrease in cold airflow being cold as it should be. If you want to tidy these up yourself, do lots of research first, but in most cases, an HVAC company will be your safest bet. 9. Reorganise Your Furniture Although it may sound unusual, but the airflow can be impacted by the placement of your home furniture. It is something to think when you are setting up that new couch or bed you just bought. Double check to make sure you’re not trapping cool air from getting into your rooms. You can fix this by moving furniture away from central air vents and ensuring nothing is blocking the pathway of the cool air. 10. Don’t forget to turn it off when going out While you might want the room to be cool when you arrive from outside, you can save a lot of money on your energy bills by turning off the AC whenever you leave the house and keeping windows closed. You should also close your shades to not have direct sunlight heating up your place when you’re not there. 11. Use Your Fan To Your Advantage Fans are a great tool to expand the reach of cool air from your AC. Strategically placing fans throughout your home can keep the cold breeze flowing into rooms without having to run AC all day.

FAQ Industrial Ventilation FAQ Frequently asked questions regarding Plymovent fume extraction and WorkSafe compliance. Why is source extraction critical for welding fumes? Source extraction captures toxic hexavalent chromium, welding smoke, and fine metal particles directly at the arc before they reach the welder's breathing zone or contaminate factory air. What does W3 certification mean in fume extraction? W3 certification guarantees that a filter unit extracts and separates over 99% of hazardous airborne particles generated during stainless steel and high-alloy steel welding operations. How does RamAir™ pulse filter cleaning work? RamAir™ uses compressed air pulses to blow accumulated dust off internal filter cartridges into a collection bin, extending filter life and maintaining continuous airflow velocity. Can mobile fume extractors handle stainless steel welding? Yes, models like MobileGo Plus and MobilePro are W3 rated and equipped with specialized filter cartridges designed specifically for stainless steel fume filtration. Do you offer scheduled filter replacement and servicing contracts? Yes, JSR provides comprehensive preventative maintenance contracts including face velocity checks, spark arrestor cleaning, filter cartridge replacement, and compliance logbook maintenance. What IQP building compliance documentation do you provide? Our trade engineers are IQP registered and provide Producer Statements (PS1–PS4) and annual 12A inspection signoffs for Building Warrant of Fitness (BWOF) compliance under Specified System 9 (SS9).

By Team JSR • 2020-09-30 • 4 min read One of our favourite habits is having a decluttered home. We’ve always disliked the clutter but put the task off because it was unpleasant. The thought of having to deal with all that clutter was overwhelming, and too much to do, so we procrastinated. Clutter, it turns out, is procrastination. But we’ve learned to deal with that procrastination one small chunk at a time and cleared it out. That was truly amazing. Amazing because when it was done, there was a background noise that was removed from our lives, a distraction, an irritation. Decluttering your home will mean a more peaceful, minimal life. It means spending less time cleaning, maintaining stuff, looking for things. Less money buying things, storing things. Less emotional attachment to things. For anyone looking to begin decluttering, here’s a short guide on getting started. Know that this guide isn’t comprehensive, and it can take months to really get down to a decluttered home … but if you do it right, the process is fun and liberating and empowering, each step of the way. Start small. Clutter can be overwhelming, and so we put it off. The best thing to do is to just focus on one small space to start with. A kitchen counter (just part of it) is a good example. Or a dining table, or a shelf. Clear everything off that space, and only put back what you really need. Put it back neatly. Get rid of the rest — give it away, sell it on TradeMe, donate it, recycle it. The clearing and sorting will take 10 minutes, while you can give stuff away later when you have the time. Work in chunks. If you start small, you’ll feel good about it, but there’s still a whole home full of stuff to deal with. How do you eat an elephant? One bite at a time. So just like you did one small area to start with, keep doing that, just 10 minutes a day, maybe more if you feel really enthusiastic. If you have a free day on the weekend, spend an afternoon doing a huge chunk. Spend the whole weekend if you feel like it. Or just do one small piece at a time — there’s no need to rush, but keep the progress going. Follow a simple method. For each small chunk you do, clear out the area in question and put everything in one pile. Pick up the first thing off the pile (no putting it aside to decide later) and force yourself to make a decision. Ask yourself: do I love and use this? If not, get rid of it. If the answer is yes, find a place for it — I call it a “home”. If you really love and use something, it deserves a home that you designate and where you put it back each time you’re done with it. Then go to the next thing and make the same decision. Working quickly and making quick decisions, you can sort through a pile in about 10 minutes (depending on the size of the pile). Put stuff in your trunk. Once you’ve collected stuff to donate or give away, put them in boxes or grocery bags and put them in the trunk of your car (if you don’t have a car, somewhere near the door). Choose a time to deliver them. Enjoy getting them out of your life. Talk to anyone involved. If you have a significant other, kids, or other people living with you, they’ll be affected if you start decluttering the home. You should talk to them now before you get started, so they’ll understand why you want to do this, and get them involved in the decision-making process. Ask them what they think of this. Send them this article to consider. Ask if they can support you wanting to declutter, at least your own stuff or some of the kitchen or living room, to see what it’s like. Don’t be pushy, don’t try to force, but have the conversation. Be OK if they resist. Try to change the things that you can control (your personal possessions, for example) and see if that example doesn’t inspire them to consider further change. Notice your resistance. There will be a lot of items that you either don’t want to get rid of (even if you don’t really use them), or you don’t feel like tackling. This resistance is important to watch — it’s your mind wanting to run from discomfort or rationalize things. You can give in to the resistance, but at least pay attention to it. See it happening. The truth is, we put a lot of emotional attachment into objects. A photo of a loved one, a gift from a family member, a memento from a wedding or travel, a treasured item from a dead grandfather. These items don’t actually contain the memories or love that we think are in them, and practising letting go of the items while holding onto the love is a good practice. And practising tackling clutter that you dread tackling is also an amazing practice. Enjoy the process. The danger is to start seeing decluttering as yet another chore on your to-do list. Once you start doing that, it becomes something you’ll put off. Instead, reframe it to a liberating practice of mindfulness. Smile as you do it. These steps won’t get your home decluttered in a weekend. But you can enjoy the first step, and then the second, and before you know it you’ve taken 30 steps and your home is transformed. You’ll love this change. Contact JSR Refrigeration and Air Conditioning Today!

By Team JSR • 2021-01-07 • 4 min read Keep Cool And Focus Hot, muggy weather is not conducive to productivity. Warm temperatures make you feel sleepy, relaxed, and sluggish – not fresh and ready to tackle anything that requires a bit of focus. The temperature of your work environment has a significant impact on how well you are able to work. One study conducted in 2015 proved what most of us intuitively know: when the temperature of our environment is comfortable, we are far more productive. If you are too hot, it’s difficult for your brain to pay attention to the job at hand. That means creative or complex tasks are going to be challenging. Whether you are working from home or in the office, you’ll find you get more done, more easily when you’re not feeling hot and bothered. An investment in a cooling or ventilation unit is a smart move for your comfort and the bottom line. Cool Down And Sleep Easy Another key factor in productivity is the quality of your sleep. In fact, if you don’t get enough deep sleep, it’s hard to get much of anything done. When it comes to falling asleep faster and getting the right kind of sleep throughout the night, temperature plays a key role. According to our natural circadian rhythms, a warmer core body temperature causes us to be alert and energetic. A cooler core temperature makes us drowsy and prepares us for sleep. The experts recommend keeping your bedroom between 15 and 20 degrees Celsius to help signal to your body that it’s time to wind down and sleep. Research shows this is especially helpful for those who suffer from insomnia. These lower temperatures stimulate melatonin production, an important chemical that encourages sleep. Cooler room temperatures not only help you get to sleep faster, but also allow you to stay comfortable, meaning you remain asleep and cycle through those important sleep cycles. Nobody likes waking up in the night dripping with sweat and dying for a glass of water. Fortunately, that is something you won’t have to worry about with an efficient cooling unit to keep things comfy and help prevent dehydration! No More Mozzies All it takes is one tiny mosquito to keep you awake or distract you from your work. Few things are as irritating! Unfortunately, if you need to crack the windows open in an attempt to cool the room down, insects are a given, especially during those balmy summer evenings. But did you know that most insects don’t like the cold? If you have a ventilation system or cooling unit to keep things fresh and comfortable, you will be able to shut the windows to keep the critters outside, and any insects already in there will be far less active. What Can You Do About It? Keeping your home or workspace cool during summer has so many benefits that most people reckon it’s worth every cent to install a ventilation or cooling unit! You’ll have better focus, sleep soundly, reduce the number of bugs, and enjoy being cool and comfy no matter what you’re doing. If you’d like to know more, contact the experts at JSR today. We will help you find the right solution for your space. Contact JSR Refrigeration and Air Conditioning Today!

HVAC Tips from JSR Refrigeration & Air Conditioning Hamilton By Team JSR • March 20, 2026 • 3 min read Prepare Your HVAC System Before Winter As temperatures begin to drop across New Zealand, autumn is the ideal time for businesses to prepare their heating, ventilation, and refrigeration systems for the demands of winter. JSR Refrigeration & Air Conditioning can help ensure your commercial space stays comfortable, productive, and compliant, while protecting valuable stock. Book a Professional System Check One of the most important steps is booking a professional system check before winter arrives. Preventative maintenance ensures your equipment is operating efficiently and helps identify potential issues before they become costly breakdowns. A poorly maintained system often works harder than necessary, leading to increased energy bills and unexpected downtime during peak usage periods. Maintain Refrigeration Performance For businesses that rely on refrigeration, such as hospitality, retail, or food storage, consistent temperature control is critical year round. Colder weather can still impact performance, particularly if systems are not regularly serviced. Checking seals, airflow, and system calibration can help avoid spoilage and ensure compliance with health and safety standards. Ensure Proper Ventilation and Air Quality Ventilation is another key factor that is often overlooked. During winter, buildings are more likely to be closed up, which can lead to poor indoor air quality if ventilation systems are not functioning properly. Regular inspections help ensure fresh airflow, creating a healthier environment for both staff and customers. Stay Compliant with Regulations It is also important to stay on top of compliance requirements. Many commercial buildings require routine inspections and certifications to meet regulations. Ensuring your systems are up to standard not only keeps your business compliant but also reduces the risk of costly disruptions. Consider Upgrades for Efficiency Finally, consider whether your current system is meeting your needs. If your HVAC equipment is outdated or struggling to perform, upgrading to a more energy-efficient solution could provide long-term savings and improved reliability. Act Now for a Smooth Winter By taking action in autumn, businesses can avoid the winter rush and ensure their systems are ready when they are needed most. With expert support and tailored solutions, JSR Refrigeration & Air Conditioning can help keep your operations running smoothly all season long. Contact JSR Refrigeration and Air Conditioning Today!

During some of life’s most challenging moments, Ronald McDonald House offers families a place to stay together, close to the medical care their children need. Supporting this charity aligns strongly with JSR’s values and our commitment to community wellbeing. Events like the Colour Run are about more than fundraising. They create opportunities for people of all ages to come together, enjoy the outdoors, and celebrate community spirit. Hosting the event at Hamilton Lake adds to the sense of connection, turning a familiar local space into a hub of energy, colour, and shared purpose. JSR is proud to stand alongside local businesses, families, and volunteers who are helping make this event possible.

The question many homeowners ask is: Do I need a new heat pump for my new home? And perhaps more importantly: How do I choose the right one? At JSR Refrigeration and Air Conditioning, we specialise in residential heat pump installation, servicing and maintenance across the Waikato region. Why a Heat Pump is a Smart Choice A modern heat pump gives you the best of both worlds. It provides warm, cosy spaces in winter and cool relief in summer. Unlike traditional electric heaters that generate heat directly, a heat pump moves existing heat from one place to another. This helps create a far more energy efficient outcome. With New Zealand’s variable climate, particularly in the Waikato where winters can be chilly and summers humid, having a system that can both heat and cool is a very smart decision. Choosing the Right Size and Model One of the most common mistakes homeowners make is selecting a system that is the wrong size for the space. If the unit is too small, it will not keep up. If the unit is too large, it may turn on and off too frequently, wasting energy and causing unnecessary wear. At JSR, our experienced team assesses your home’s size, insulation level, orientation, window size and layout. This ensures you receive a unit that delivers both performance and efficiency. What to Look Out For Warranty and support: JSR proudly partners with trusted brands and offers excellent warranty options on selected systems.

JSR Refrigeration and Air Conditioning recommends a few simple adjustments to make a noticeable difference in comfort, performance, and power bills. 1. Set and forget your temperature Avoid constantly turning your heat pump on and off. Instead, set it to a steady, comfortable temperature (typically around 18–21°C). Heat pumps work best when maintaining a consistent environment rather than reheating a cold space from scratch. 2. Use Heat Mode, not Auto In colder weather, always switch to heat mode. Auto mode can cause the system to switch between heating and cooling, which wastes energy and reduces efficiency. 3. Don’t crank it to the max Setting your heat pump to 30°C won’t heat your room faster. It simply makes the unit work harder for longer, increasing energy use. Stick to a realistic temperature and let the system do its job. 4. Keep doors and windows closed Heat escapes quickly in winter, so keep the space sealed to maintain warmth and reduce workload on the unit. 5. Clean your filters regularly Dirty filters restrict airflow and force your heat pump to work harder. A quick clean every few weeks during heavy use can improve performance and air quality. 6. Make use of timers and scheduling Pre-warm your home before you wake up or return in the evening. This keeps your space comfortable without running the system unnecessarily all day. 7. Ensure good airflow Keep furniture, curtains, and other obstructions away from the indoor unit so heat can circulate evenly. 8. Don’t worry about defrost cycles On very cold mornings, your outdoor unit may briefly stop heating while it defrosts. This is normal and helps maintain efficiency. 9. Insulation matters Even the best heat pump struggles in a poorly insulated home. Sealing drafts and improving insulation can significantly boost performance. Used properly, a heat pump remains one of the most cost-effective heating options through winter. Following these tips from JSR Refrigeration and Air Conditioning can keep your home warmer, drier, and more energy-efficient all season long. Contact JSR Refrigeration and Air Conditioning Today!

When it gets cold, we throw on a jumper and another pair of socks. But, when the temperature drops into single digits (or below), a jumper and warm socks don’t quite cut it. You need an efficient source of heating as well. While a cheap heater from your local department store will warm the air around itself, it isn’t going to provide the sustained, energy-efficient heating you need. For that, you will require something like a heat pump. They are the most sustainable way to heat your home, only operating to bring the room up to the temperature you want and keeping it there. At all other times, it doesn’t draw on your energy resources. If you then couple your heat pump with a ducting system, you can heat all the corners of your home with one device. That means you can throw away those fan or oil fin heaters in your bedrooms. You won’t need that drain on the power bill anymore! Ducting systems efficiently transfer heat throughout your home (or cool air in the summertime). And the great news is that we currently have specials running on both our heat pumps and ducting systems. You can check them out by clicking here. Good Heating Tips Pushing the button on your brand new (or newly serviced) heat pump is a great start. But, there are a few best practice tips to keep in mind. They are: Don’t set the temperature to maximum. It won’t heat the room quicker, it will just use more energy! Use the timer function so it comes on 15 mins before you need it, then you don’t have to turn it on before you even leave the house. You can even select a model that is compatible with your Smart Home apps and control it from your devices. Turn it off when you don’t need it Heat the rooms that you are using. Close off spaces like the laundry and garage to prevent heat from escaping Close the curtains to keep the heat in Ensure your home is fully insulated to make your heating more efficient Maintaining Your Heat Sources Like anything, your heat pump needs a bit of maintenance to operate at maximum efficiency. After all, you wouldn’t drive your car around without taking it for a regular service or WOF. So, why would you try and operate your heat pump without maintenance? Over time, heat pumps can collect pollutants from the air. These can be redistributed into your home unless you take the time to clean your filters and coils. These collected particles can also make it difficult for your heat pump to run at normal capacity, costing you more in energy bills. However, a regular service can help your heat pump run in optimum form all year round. While you can do some of the maintenance yourself, cleaning the filters is only half of the job. It is best to call in a professional to fully service the system on an annual basis. This can bring any faults to your attention, preventing the need for costly repairs in the long term. Making Your Money Work For You It is true that a heat pump is an investment. However, you can make your money work for you as we have great finance options available at JSR. As well as all the standard payment methods, we also offer finance options via GEM Visa. Spread the payments out over time and get great interest deals. That means you can get the heating solutions you need without any of the payment stresses. If you would like to make use of our finance options (or any of our other services) then simply mention it to our team when you are discussing your heating system. We would love to help you keep your home or office warm this winter! If you are looking for a heat pump, a ducting system (or both), then get in touch with us today.

This hectic day-to-day scramble won’t just run you ragged, it’ll ultimately also hold your business back, and keep you from developing and implementing your best ideas. To turn their business into an industry leader, entrepreneurs need to not only do the job of running their business, they need to personally dedicate the necessary time to think bigger. Leading an industry is about becoming the cutting edge of innovation in your field, and being the disruptive force that sets the pace for your competitors. This is a big responsibility and requires a comprehensive understanding of the needs of your markets and the capabilities of your industry and your business. Making that innovative leap is about taking that knowledge and using it to dream up a better future. Time for reflection allows for higher quality thinking Business owners spend most of their day in a neverending rush of activity. When there aren’t clients, employees, and suppliers to talk to and manage, lenders to negotiate with, bills to pay, taxes to do, and meetings to run, there are thousands of emails to sort and answer. Individual tasks are allotted just a few seconds of focus before the next issue comes up. In this type of environment, it’s very easy to lose sight of the forest for the trees. This is a serious problem, because business owners need to have a larger scale view, and the opportunity to build and develop larger and longer-term goals and strategies. They need time to dream about what might be, and how to make the impossible achievable. Dreams are the engine of innovation A business owner that is always focused on getting through the day will ultimately only ever build a business that’s focused on, and perhaps good at, survival. An entrepreneur takes time to think deeply about their business, their industry, and what their place in the world is and what it could be. Without this larger vision, growth targets and strategies lack a unifying purpose, and can’t spur on the kind of targeted innovation that a business needs to set itself up as a leader in its industry. Improving time management The missing resource that leaders at every level lack is time. This is because, before business owners can make time for themselves, they need to get control of their schedule, which becomes increasingly difficult as responsibilities grow. All too frequently, business owners become a sort of jack of all trades, handling all the miscellaneous tasks that their employees aren’t responsible for. That might include everything from administrative tasks like payroll and accounting, to customer relations or sales, to menial maintenance tasks like cleaning and emptying the garbage. Inevitably, these day to day tasks crowd out longer term and less well-defined leadership responsibilities, like setting the long term goals and overall trajectory of the business. Delegate tasks While greatly reducing the time spent on dealing with cash flow issues is a big improvement, entrepreneurs frequently work as much as 80 hours per week. To reach a point where they legitimately have free time to dedicate to higher order, long-term planning, business owners usually need get control of their schedule and to bring their working hours down to reasonable levels. Ultimately, this means learning to delegate some responsibilities to employees, or outsourcing tasks another way. This is tough, because business owners tend to take a lot of ownership over their business, and feel the need to be in control of every aspect of their operation. Making time means making tough decisions about which tasks really need and deserve their attention, and which can reasonably be delegated. Ultimately, however, making these choices is for the best. By taking their eyes off short-term issues that can be handled by others, they can take the time to dream up a better future for their business, their customers, and their industry.

FAQ Mortuary Equipment FAQ Frequently asked questions regarding mortuary refrigeration and embalming room ventilation. Why is 12 air changes per hour (ACH) required in embalming and autopsy rooms? WorkSafe New Zealand guidelines mandate at least 12 air changes per hour (ACH) to continuously purge bio-aerosols, chemical embalming vapors (such as formaldehyde), and airborne pathogens, protecting staff health. Why must autopsy suites operate under negative pressure? Negative pressure ensures air flows into the autopsy room when doors are opened, preventing odors, airborne microbes, and chemical fumes from escaping into surrounding office, corridor, or reception areas. What is downdraught ventilation and how does it protect operators? Downdraught ventilation introduces clean air from ceiling diffusers and extracts air through low floor or skirting vents near the autopsy table. This pulls airborne contaminants downward away from the operator's breathing zone. Why do mortuary chillers use dual redundant cooling systems? Dual redundant systems install two complete, independent refrigeration circuits. If one compressor or refrigeration system fails, the secondary system automatically maintains temperature to prevent room warm-up. How are viewing rooms ventilated for observers? Viewing galleries are physically separated by sealed glass partitions and operate on a completely separate, positive pressure ventilation loop, isolating observers from the high-risk suite environment.

What to do if you have a problem now… Our tradespeople are currently able to undertake maintenance and repair of heat pumps and air conditioning units in residential properties and essential businesses. This is because heating and refrigeration are necessary to maintain the necessities of life or are critical to safety! If you have an issue that needs addressing, then please contact us via phone (0800 577 722) as our offices and workshops remain closed during this time. Our technicians are working remotely with all the necessary tools and supplies on hand. Keeping Everyone Safe While repairs and maintenance are essential, we want to make sure we are keeping everyone safe. That includes you and your family as well as our technicians. That is why our entire team is currently working remotely so that we don’t have unnecessary contact in the office or workshops. Each technician is assigned to a job and has the necessary equipment on hand to come straight to your residence or premises. Our entire team are following the health guidelines set out by the authorities for both Level 4 and when we move to Level 3. That includes physical distancing, hand and tool washing, as well as wearing protective equipment. This ensures the health and safety of themselves as well as those around them during these unsettling times. Helping Out The Community Even though times are uncertain right now, the goodness of humanity still shines through. You may have heard the saying “look for the helpers”. When a crisis or disaster takes place, it can be hard to process it. It is easy to feel overwhelmed and upset. But, despite the chaos, in every crisis, there will be helpers. If you look for them, you will see the shining light in the situation. Throughout the pain and suffering, people will be kind and giving. The Serve Trust are those helpers in many situations. And recently, here at JSR, we gave them a lifeline so that they can continue to help in these troubling times. The Serve Trust distribute meals and resources throughout the Waikato community to those that need them the most. Because of the current situation, they had to temporarily close their walk-in premises due to the need for social distancing. They are now delivering meals to the door to door instead. We knew we wanted to do our part to help such a worthy cause, so donated the use of a mobile chiller free of charge to help The Serve complete their valuable work. As of mid-April, The Serve had delivered close to 5000 meals. They deliver to 240 homes a night and have delivered more than 900 meals to those living on the streets. Without their generosity, many families would be struggling in these restrictive times. Remember that the team here at JSR are able to help with any of your emergency repair and maintenance work. Simply give us a call on 0800 577 722 and we can arrange to have a technician out to you as soon as possible. Contact JSR Refrigeration and Air Conditioning Today!

FAQ On-Farm Refrigeration FAQ Frequently asked questions from Waikato dairy farmers. How fast is your 24/7 emergency response for milk vat breakdowns? We understand that milk vat cooling is time-critical. Our on-call farm technicians are stationed throughout the Waikato region with fully equipped service vans for rapid 24/7 emergency dispatch. Why is pre-milking season servicing so important? A pre-season check ensures your compressors, plate heat exchangers, and controls are leak-free and operating at peak efficiency before daily milking starts. This avoids costly milk degradation or rejection by processors. What is milk pre-cooling and how does a plate heat exchanger help? A plate heat exchanger uses farm bore water to drop milk temperature from ~37°C down to near water temperature before it enters the vat. This reduces vat refrigeration workload by up to 50%, saving significant power. Can solar power run dairy shed refrigeration? Yes! Because daytime milking coincides with peak solar generation, solar panels offset the heavy electricity load of vat refrigeration and water heating, reducing overall farm operational costs. What condensing units do you use for farm refrigeration? We install heavy-duty Patton refrigeration condensing units rated for up to 45°C ambient temperature. Their larger condensers handle harsh summer ambient heat without tripping or losing cooling capacity. Do you help with MPI temperature compliance documentation? Yes, all our farm refrigeration installations and upgrades are engineered to meet strict MPI raw milk cooling regulations and temperature logging standards.

The region’s three councils are also warning residents to use water wisely, with the heat expected to hang around for at least another week. Alpine Energy general manager network Willam Rawlins said several power demand records had been passed in the region in the past few days, with the company reporting record demand as offices run cooling systems and farmers use instigators. he company only measures maximum demand numbers for power, so the largest amount of electricity that is passing through the network at that time – the power peaks, not usage. On Tuesday Timaru today recorded 62.6 MW. “This is the highest summer peak on record, up 16 per cent from the 2016 summer high of 54 MW, and up 28 per cent on the summer 2015 peak of 49 MW,” he said. Rawlins said the peak in winter had been 67 MW. He said the hot weather had contributed to the peaks. “In Timaru a lot of that will be from people running cool stores and offices that run air conditioning.” At other substations throughout the district, irrigation was contributing to a peak, he said. He said on December 2, the Bells Pond substation, near Glenavy, recorded 13.74MW of electricity – the highest power peak on record at the station and up 15 per cent on the previous high recorded last year. “This is mainly due to irrigation consumption, one of those being the Waihao Downs Scheme and some from increased capacity at Oceania Dairy who are now also operating a UHT plant,” he said. The Temuka substation also recorded it highest power peak on record of 57.7 MW on December 4, which is 2.5 MW higher than the previous peak recorded in November 2015 during a similar hot spell. Mackenzie District Council utilities manager Geoff Horler said water use in the district had been “extremely high” in the past few days. He said while every town in the Mackenzie was different, overall water use had been high for this time of the year. he company only measures maximum demand numbers for power, so the largest amount of electricity that is passing through the network at that time – the power peaks, not usage. On Tuesday Timaru today recorded 62.6 MW. “This is the highest summer peak on record, up 16 per cent from the 2016 summer high of 54 MW, and up 28 per cent on the summer 2015 peak of 49 MW,” he said.

Mackenzie District Council utilities manager Geoff Horler said water use in the district had been “extremely high” in the past few days. He said while every town in the Mackenzie was different, overall water use had been high for this time of the year. No water restrictions were in place but the council was reviewing that status on a “daily basis”, he said. “It’s early summer but it’s what you’d expect the usage to be in January. “Use timers if you’re using water,” Horler said. Waimate District Council water and waste manager Paul Roberts said there was no high demand on water, at the moment, that warranted a restriction. “We will only put on restrictions when we have issues,” he said. Timaru District Council communications manager Stephen Doran said there were no water restrictions in place yet for the district. However, residents were encouraged to conserve water. Thompsons Refrigeration and Air Conditioning owners Jeremy and Jadie McDonald had “definitely” noticed an increase in the number of customers needing their air conditioning units serviced in the past week. “Everything works harder in more extreme conditions,” Jeremy said. “For things to work properly in the heat they [air conditioning units] have to be clean and tidy. They won’t make it on a long, hot day.” He said they were busy with extra jobs because of the heat. The work had been for a range of equipment, including a slushy machine, he said. Jadie McDonald said there had also been an increase in the number of people coming in needing their car air conditioning units repaired. “People don’t really get their car air conditioning fixed normally,” she said. “With the constant days of heat though people have noticed they need it fixed.” Timaru electrical repair company Sullivan and Spillane owner Sarah Pierce said generally the business’ busy time for heat pump repair was winter. “Usually a bit of a lull at this time of the year,” Pierce said. “The momentum is ticking along though with people enquiring about their heat pumps.” She said traditionally people had seen heat pumps as an appliance to heat the home. “More people could be using the airconditioning option,” she said. Waimataitai Kindergarten teacher Rachael Polson said the hot weather had seen classes being moved to outdoors. “We have had the sprinklers going and the kids out underneath it,” she said. “We’ve had a lot of water out and we’ve been sitting out in the shade.” She said the hot weather was generating the kind of temperatures the kindergarten had been used to in about February and March. “It’s been about lots of water and sunhats.” South Canterbury SPCA Timaru manager Barry Fairbrother said animal welfare during the warmer weather was all about “common sense”. “Move them to shade or create shade for them and provide plenty of water,” he said. He said farmers knew what to do in extreme weather conditions, and traditionally stock would find their own shade in intense heat. Niwa meteorologist Ben Noll said the “unseasonable” heat looked set to stay for a while. “For the next week or so it looks like it’s going to be pretty toasty,” he said. “It’s been a very hot start to summer.” – The Timaru Herald Reference: https://www.stuff.co.nz/timaru-herald/news/99543687/record-peak-power-demand-as-weather-heats-up Contact JSR Refrigeration and Air Conditioning Today!

FAQ Refrigeration Cabinets FAQ Frequently asked questions about commercial display cabinets and food fridges. What is the difference between self-contained and remote compressor cabinets? Self-contained plug-in cabinets have the compressor built inside the base of the cabinet, ideal for easy setup and movement. Remote compressor cabinets connect to an outdoor refrigeration condensing unit, reducing noise and heat inside your store. What temperature range do bakery and cake display cabinets hold? Chilled cake and patisserie showcases maintain +2°C to +8°C with gentle, high-humidity airflow to keep cream, cakes, and pastries fresh without drying them out. Why are Pastorfrigor multidecks popular for supermarkets and delis? Pastorfrigor multi-deck cabinets offer superior European design, ultra-bright LED product illumination, maximum shelf depth, and precise air curtain technology to maintain constant internal temperatures during heavy customer access. How often should commercial display cabinet condenser coils be cleaned? We recommend cleaning condenser coils every 1 to 3 months. Dust and grease buildup causes compressors to overheat, raising electricity bills and risking sudden breakdown during peak trade. Do you offer 24/7 emergency repair if my display cabinet fails? Yes, JSR Refrigeration provides 24/7 emergency breakdown support across Hamilton and Waikato. Our technicians arrive with common spare parts to repair your unit and protect valuable food stock. Can you supply under-bench prep refrigerators for commercial kitchens? Yes, we supply stainless steel under-counter refrigerators, salad prep tables, pizza prep counters, and blast chillers built to withstand high-volume kitchen use.

FAQ Refrigeration Service & Repair FAQ Common questions regarding refrigeration maintenance and emergency repairs. Why should I invest in a planned preventative maintenance program? Preventative maintenance catches component wear, gas micro-leaks, and dirty coils before they cause complete breakdown. It lowers electricity costs, extends equipment life, and prevents thousands of dollars in lost stock and emergency callout fees. How fast can a technician arrive for an emergency breakdown? We operate 24 hours a day, 365 days a year across Hamilton and Waikato. Our service vans are stocked with replacement parts for fast, on-the-spot emergency repairs. How often should commercial refrigeration equipment be serviced? We recommend quarterly (every 3 months) or bi-annual servicing for high-demand commercial chillers, supermarket cabinets, and dairy farm milk vats to maintain optimal performance. What are the signs that my refrigeration unit has a gas leak? Common signs include the unit running continuously without reaching temperature, ice buildup on evaporator coils, higher electricity bills, or unusual clicking/hissing noises from line sets. What is R22 refrigerant phase-out and how does it affect my system? R22 is an older ozone-depleting refrigerant being phased out globally. If your old unit uses R22, replacement gas is expensive and hard to source. We help businesses retrofit or replace aging R22 systems with modern eco-friendly refrigerants. Do your service technicians provide IQP 12A signoffs for compliance? Yes, all our engineers are IQP registered and qualified to perform mechanical ventilation and refrigeration inspections, providing Form 12A signoffs for your Building Warrant of Fitness (BWOF).

FAQ Residential Heat Pump FAQ Frequently asked questions about home heating and air conditioning in Hamilton. What is the difference between a high wall split system and a floor console? High wall systems mount near the ceiling to maximize floor space and cool efficiently in summer. Floor consoles sit near floor level (often replacing old fireplaces), blowing warm air across floor level for rapid winter heating comfort. What is the difference between Daikin LITE and Daikin ALIRA series? Daikin LITE is an affordable, stylish entry model with Intelligent Eye motion sensors. Daikin ALIRA is Daikin's premium model offering higher energy star ratings, built-in Wi-Fi, Streamer air purification tech, and lower noise levels (19dBA). How does a Multi-Room (Multi-Split) heat pump work? A multi-split system connects up to 5 indoor units in different bedrooms or living rooms to a single compact outdoor compressor unit. Each room gets its own independent remote controller and temperature settings. How do smart Wi-Fi controllers and voice control work with heat pumps? Units like Hitachi Ciara and Daikin Alira have built-in Wi-Fi cards that connect to your home internet router. You can adjust temperature from your smartphone app before leaving work or use Google Assistant / Alexa voice commands at home. How much electricity does a modern inverter heat pump use? Inverter heat pumps deliver up to 3 to 4 times more heat energy than the electrical power they consume (COP 3.5 to 4.5).

By Team JSR • 2024-07-17 • 4 min read Should You Repair Or Replace Your Heat Pump: Which Costs Less? By Team JSR In the depths of winter, New Zealand experiences a biting cold. The day starts with frosty mornings with occasional rain all around the chilly afternoon and freezing evenings spent curled up at home. To withstand the cold, many of us rely on an exceptional heating system such as the heat pump, which keeps you and your family warm. Keeping a comfortable indoor temperature not only boosts our immune system and helps prevent colds but also turns our home into a cosy and happier place. There will be a point in time where your heat pump system will start to break down and cause uneven cooling or heating. Common issues in a Heat pump can arise such as refrigerant leaks, compressor failures and defrost cycle malfunctions etc. As a homeowner, you will have to make the biggest financial decision on whether to repair your current heat pump or and replace with a newer, modern heat pump. Both options are a viable choice, but they do have their pros and cons. The choice you make can significantly impact your wallet. To help you make the right choice, let’s break down the details when deciding between repairing your heat pump or purchasing a new one. Evaluating the Costs Short Term Costs Repairing: Lower Priority Cost: Repairing your heat pump system typically costs less upfront compared to purchasing a new one. Common repairs might include fixing leaks, replacing belts, or repairing electrical components, which can range from $150 to $1000 depending on the issue. Replacing: Higher Priority Cost: Replacing your heat pump system involves a significant investment. The cost for a new system, including installation, can range from $2,000 to $7,000 or more, depending on the size of your home and the type of system you choose. Long Term Costs Repairing: Recurring Expenses: An older heat pump system is more likely to require frequent repairs, which can add up over time. If your system is already 10–15 years old, these costs can become a costly and a burden on your wallet. Replacing: Energy Efficiency Savings: Newer heat pump systems are more energy-efficient, which can lead to lower utility bills. This energy efficiency can result in significant savings over the system’s lifespan, potentially offsetting the initial investment. System Efficiency and Performance Repairing: Declining Efficiency: As heat pump systems age, they tend to lose efficiency, even with repairs. An older system may struggle to maintain a comfortable temperature, leading to higher energy usage and costs. Upgrade Limitations: Repairing an old system doesn’t typically allow for significant efficiency upgrades. You’re essentially extending the life of an outdated model. Replacing: Improved Efficiency: New heat pump systems come with advanced technology designed to maximise efficiency and performance. Features like programmable thermostats, variable speed motors, and improved refrigerants can enhance comfort and reduce energy consumption. Enhanced Comfort: A new system can provide more consistent heating and cooling, improved humidity control, and quieter operation, enhancing overall comfort in your home. Economical Considerations Repairing: Extended Use of Existing Materials: Repairing your heat pump system means you’re not contributing to landfill waste or the production demands of a new system. However, older systems might use outdated refrigerants that are less environmentally friendly. Replacing: Eco-Friendly Options: New heat pump systems are designed with environmental considerations in mind. They use refrigerants that are less harmful to the ozone layer and are more energy-efficient, reducing your carbon footprint. Making The Decision The Age Of Your System Under 10 Years: If your heat pump system is less than 10 years old and has been well-maintained, repairs might be the more cost-effective option. A newer system is likely still under warranty, and the cost of repairs might be minimal. Over 10–15 Years: If your system is over 10–15 years old, replacement is often the more economical choice. Heat pump systems typically have a lifespan of 15–20 years, and older systems are less efficient and more prone to breakdowns. Frequency And Cost Of Repairs Infrequent, Low-Cost Repairs: If repairs are infrequent and not too costly, continuing to repair your existing system can be a wise decision. Frequent, High-Cost Repairs: If you find yourself frequently calling the repair technician and the costs are adding up, it might be time to invest in a new system. Continual repairs can quickly outweigh the cost of a replacement. Energy Bills Rising Energy Costs: If your energy bills have been steadily increasing despite regular maintenance, it’s a sign that your heat pump system is losing efficiency. A new, energy-efficient system can reduce your monthly utility bills. Comfort And Air Quality Decreased Comfort: If you’re experiencing uneven temperatures, poor humidity control, or increased dust and allergens, your old heat pump system might not be up to the task. A new system can significantly improve indoor air quality and comfort. Deciding whether to repair or replace your heat pump system is not a one-size-fits-all answer. It requires evaluating the age and condition of your current system, the frequency and cost of repairs, and your long-term energy savings goals. While repairing your old heat pump might be cheaper in the short term, investing in a new system could provide better efficiency, performance, and cost savings over time. Assess your needs carefully and consult with our professional JSR heat pump technician to make the best decision for your home and budget. Contact JSR Refrigeration and Air Conditioning Today!

Whether you’re a home-owner or a renter, these tips will help you create a cozy and cost-effective living environment. Four Steps To A Warm and Drier Home Insulation, heating, ventilation, and dampness control work together to maintain a comfortable and healthy home. As winter approaches, balancing warmth and affordability becomes crucial. Follow these steps to ensure a warmer home this winter: 1. Insulation Why it’s important: Insulation is the key to a comfortable home during winter. It helps retain heat, making it easier and cheaper to keep your home warm. Different ways for improving home insulation: Attic Insulation: Adding insulation to your attic helps prevent heat from escaping through the roof. Wall Insulation: Filling cavity walls with insulation material or adding insulating boards to solid walls. Floor Insulation: Using insulating materials under floorboards or installing carpet to reduce heat loss through floors. Window Insulation: Applying weather stripping, using thermal curtains, or installing double-glazed windows to reduce drafts and heat loss. Door Insulation: Sealing gaps around doors with weather stripping or using draft excluders. Pipe Insulation: Wrapping hot water pipes with insulating material to retain heat and prevent freezing. Loft Hatch Insulation: Adding insulation around the loft hatch to prevent warm air from escaping. Basement Insulation: Insulating basement walls and ceilings to reduce heat loss from below the house. Radiator Reflectors: Placing reflective panels behind radiators to direct heat back into the room. Exterior Insulation: Applying insulation to the exterior walls to improve overall thermal 2. Dampness Control Different ways for improving dampness: Use a Dehumidifier: Place portable dehumidifiers in damp-prone areas to reduce moisture levels. Open Windows Regularly: Briefly open windows each day to allow fresh air to circulate and reduce indoor humidity. Use Exhaust Fans: Turn on exhaust fans in kitchens and bathrooms to expel moisture-laden air. Wipe Down Surfaces: Regularly wipe down windowsills and other surfaces where condensation forms. Dry Clothes Outside: Hang laundry outside or in a well-ventilated area instead of drying clothes indoors. Install Moisture Absorbers: Place moisture-absorbing crystals or packets in closets and small, enclosed spaces. Fix Leaks Promptly: Repair any leaks in roofs, pipes, and faucets to prevent water accumulation. Keep Gutters Clean: Ensure gutters are clear of debris to prevent water overflow and seepage into walls. Use Bathroom Rugs: Lay down absorbent mats in the bathroom to capture water spills and reduce floor dampness. Seal Gaps and Cracks: Use caulk or weather stripping to seal gaps around windows and doors where moisture can enter. 3. Ventilation Why it’s important: Proper ventilation maintains good air quality and removes daily moisture. Striking the right balance is essential—too much ventilation can make it hard to keep your home warm, while too little can lead to poor air quality. Different ways for improving ventilation: Use Exhaust Fans: Operate exhaust fans in the kitchen and bathroom to remove moisture and stale air. Open Windows Briefly: Open windows for short periods daily to allow fresh air to circulate without significantly losing heat. Trickle Vents: Install trickle vents on windows to allow continuous airflow while keeping windows closed. Ceiling Fans: Use ceiling fans set to winter mode (clockwise) to circulate warm air and improve ventilation. Window Ventilation Locks: Use window locks that allow windows to be left slightly open for ventilation without compromising security. Air Bricks: Ensure air bricks and vents are unblocked to allow airflow under floors and within cavity walls. Mechanical Ventilation with Heat Recovery (MVHR): Install an MVHR system to provide fresh air while recovering heat from outgoing air. Door Grilles: Install grilles or vents in interior doors to facilitate airflow between rooms. Cross-Ventilation: Create cross-ventilation by opening windows or vents on opposite sides of the home to allow fresh air to flow through. Regularly Clean Vents and Filters: Clean air vents and replace filters in ventilation systems to maintain efficient airflow and air quality. 4. Heating Why it’s important: Even with good insulation and ventilation, your home will need a reliable heat source to stay warm and dry. Be mindful of your choice of heater and fuel, as they significantly impact your winter energy bills. Different ways for improving warmth: Central Heating Systems: Use a gas, oil, or electric central heating system with radiators or underfloor heating. Space Heaters: Utilise portable electric heaters, such as fan heaters, oil-filled radiators, or ceramic heaters, for additional warmth. Heat Pumps: Install air-source or ground-source heat pumps for efficient heating. Wood Stoves and Fireplaces: Use wood-burning stoves or fireplaces for a traditional and cozy heat source. Pellet Stoves: Opt for pellet stoves that burn compressed wood or biomass pellets. Electric Blankets: Use electric blankets or heated mattress pads to keep beds warm. Infrared Heaters: Install infrared heaters that warm objects and people directly, rather than heating the air. Radiant Floor Heating: Use electric or hydronic radiant floor heating systems to warm floors and provide consistent heat. Gas Heaters: Employ portable gas heaters, ensuring proper ventilation to avoid carbon monoxide buildup. Smart Thermostats: Install smart thermostats to optimise heating schedules and improve energy efficiency. Tackling Dampness Dampness is the primary enemy in your quest for a warm and healthy home. Reducing dampness improves comfort and health, as damp air requires more energy to heat. Simple and cost-effective measures can significantly decrease moisture levels in your home. Ventilation is crucial for removing damp and stale air. It’s a delicate balance: too much ventilation makes it hard to keep your home warm, while too little can degrade air quality. Aim to find the right equilibrium for your home. Efficient Heating Heating accounts for a significant portion of your winter energy bill. Your choice of heater and heating fuel affects both costs and environmental impact. Consider the heat requirements for different rooms, the purchase and running costs of heaters, and the environmental effects of various fuels to maximise efficiency and minimise expenses.By following these steps, you can ensure a warmer, healthier, and more cost-effective home this winter.

By Team JSR This blog will help you learn the basic information of the refrigeration and air conditioning system. You’ll learn about how they work, the types, and the advantages of having them at your workplace. Refrigeration System What are the Advantages of a Refrigeration System? The refrigeration system is a mechanical device that is used to produce and maintain a cool environment in buildings or other enclosed spaces. It works by reducing the temperature of its surroundings below the dew point of water, either by evaporating water or by compressing air. The refrigeration system has many advantages, including: – It reduces the use of energy and saves money– It reduces the risk of spoilage in stored food products– It improves employees work productivity– It increases comfort levels for occupants– The refrigeration system can be used to cool down an entire building or just specific rooms How Does a Refrigeration System Work? A refrigeration system is a thermodynamic heat pump that moves heat from one location to another. The refrigerant cycle is a four-step process of absorption, compression, condensation, and evaporation.The refrigerant cycle begins when the compressor compresses the vaporized refrigerant gas into a high-pressure liquid. This liquid enters the condenser, where it is cooled by exchanging heat with air or water.The condensed liquid then moves through an expansion device to become a low-pressure gas again, which enters the evaporator and absorbs heat from inside the refrigerator. The gas then moves to the compressor in order to repeat this process over and over again. What Are The Different Types Of Refrigeration Systems Services Provided For Businesses?

Air conditioners come in many shapes and sizes, from window units to large central systems.When you install an A/C, it provides many healthy benefits to your home or offices, including: Reduces High Humidity Lowers the chances of asthma/ breathing problems Improves Air Quality Cooling reduces heat Stops insects & parasites Prevents Odours Build-ups How Does an Air Conditioning System Work? An air conditioning system is a mechanical device that removes heat from a building. It does this by cycling refrigerant between the inside and outside the building. The refrigerant absorbs the heat from the inside air and releases it outside, while simultaneously removing moisture from the indoor air. The cycle repeats until either there is no more heat to remove or until it reaches a desired temperature. An air conditioning system may also be called an HVAC (Heating, Ventilation, and Air Conditioning) system, or simply AC for short. Inside Parts of an Air Conditioning Unit and What they do? An air conditioning unit is a device that cools and dehumidifies the air in a room. The inside parts of an AC unit can be classified into two main categories: the condenser and the evaporator. The condenser is responsible for converting refrigerant gas into liquid, so it can be cooled in order to release heat. It also removes heat from inside the home by releasing it outside through a long copper pipe called a coil. The evaporator, on the other hand, takes in warm air from inside your home and changes it into cool air that gets distributed throughout your home or office. What Are The Different Types Of Air Conditioners Systems? Window Air Conditioners Portable Air Conditioners Wall Hung Split or Multi Head Split Air Conditioners Ducted Air Conditioning For more information about which air conditioning system is right for you, get in touch with us. What is the Difference Between a Heat Pump and an air Compressor? A heat pump is a device that uses a refrigeration cycle to move heat from one place to another. A compressor is a mechanical device that increases the pressure of air or gas by reducing its volume. The main difference between the two is that a compressor does not use refrigerant, and it doesn’t move heat from one place to another, it just pressurizes the air. Overall, we hope that you’ve learned the ins and outs of the refrigeration and air conditioning systems for your commercial place. Want HVAC or Refrigeration systems Installed at your place?

To make sure you don’t make the wrong decision, we have put together our tips on what to look for when buying a house… 1: Know Your Must Haves Have you been dreaming of a big backyard, an open plan kitchen, or a double garage? Before you begin your search, decide on the things that are absolutely vital to your lifestyle and hunt for those. If a house doesn’t meet your must-have criteria then don’t settle for it, you will only resent your decision in the long run. 2: Start At The Top Before you even set foot inside the house, check the roof. If it is old and worn then it could end up costing you a lot to fix in the near future. But if it looks newer and well cared for then it should last for years to come. 3: Fresh Paint Could Be Hiding Something Freshly painted walls look lovely, but look beyond the paint job to the base elements. Check the quality of the walls and floor, see if there is any damage, look for loose wires, and ageing appliances. If the house looks old and rickety then it probably is. The foundations matter more than the updated decor. 4: Examine The Plumbing Check the kitchen, bathrooms and hot water cylinder for any signs of leaks, water damage, or mould. Also, check what the water pressure and temperature are like. 5: Check The Location Look at where the house is situated. Will it be prone to flooding or exposed to the weather? What is the driveway like – is it steep, or shared with other properties, and does it have enough room for all your vehicles? Also look at the fencing and how the property is positioned for the sunlight. These are things that you cannot easily change, so it is best to cover them off before you buy. 6: Check The Insulation Situation Houses that aren’t insulated properly can be cold and damp. Check that the walls and ceilings are well insulated to reduce heating costs in winter and cooling costs in summer. Bonus points if the windows are double glazed as that not only improves your insulation, but also your soundproofing. 7: Inspect Everything Buying a house is one of the biggest investments you will make, so ensure you are getting your money’s worth. Before you buy, turn on all of the lights, taps and showers to check they are working. Flush the toilet, open all the doors and cupboards, check the inbuilt appliances and taste the water. Then, once you are happy with everything that you inspected, pay a professional to inspect it too. Contact JSR Refrigeration and Air Conditioning Today!

By Team JSR • 2019-03-08 • 4 min read Are you like many of the new home owners that have bought a new house without any form of Air conditioning and then suffered over the heat wave we had during early February? Thankfully that extreme heat has settled down ( and before you know it the colder days will be upon us!) You may be planning ahead so you don’t sit freezing this winter and of course not repeating the uncomfortable feeling when we get the next hot spell? Heat Pumps New Zealand has seen a rise in the installation of heat pumps as a source of heating (and cooling) in recent years, and with so many different makes and models it can be a bit daunting choosing which will better suit your needs. so lets break it down into sections: Firstly – What exactly does a heat pump heat your home? If you think of a Heat pump as your refrigerator working backwards, it takes the warmth from the outside air and transfers it into your indoor space. And of course it works in the opposite direction when you wish to cool your room in the summer. What Size do I need for my house? Well this depends on the size of the space and also the environment you live in. The environmental factors and the size of the space are one of the most crucial factors in ensuring that you heat pump works efficiently. If you buy a heat pump that is too small for the room size it will struggle to keep the room at the desired temperature and will use more energy trying to do so. If you buy a unit that is too large for the space, then it will turn on and off to keep the room at the set temperature, again this will not be energy efficient. For help in deciding what size is best for your home, contact us for a free home assessment. Energy Efficiency New Zealand is a land of many seasons, but if you take some time to research the options you can heat your home more efficiently. Efficiency of a heat pump system is not constant – it varies along with the temperature differential between indoor and outdoor air. A heat pump’s rated efficiency is for an outdoor temperature of 7°C, so when designing a system, it is important to understand how it will perform at lower temperatures. Whether a heat pump is in heating or cooling mode, as the difference between outdoor temperature and desired indoor temperature increases, the efficiency of a heat pump system decreases. Figure 3.4, shows the efficiency of a heat pump in heating mode reducing as the outdoor temperature decreases. Different heat pumps will perform very differently at sub-zero temperatures – some may keep performing down to -20˚C while others will struggle at temperatures below freezing. – Heat pumps can be the most energy efficient type of heating/cooling using electricity as long as you choose the right system for the space it will be heating. The most energy efficient qualify for Energy Star Qualification. If you want to thoroughly check the options available, you can use this link to compare your choices and see which brand/model will be best for your home. Defrost Cycle Another temperature-related factor that can impact on efficiency is the extra energy that may be required for defrosting at low temperatures. Ice build-up occurs at around at 0-4˚C (especially in high humidity), when any water vapour in the air will start to condense and freeze onto the evaporator (outdoor heat exchanger) coils. To remove ice build-up on the coils, most heat pumps have a defrost cycle where the system switches into cooling mode (taking some heat from inside), which could effectively cool the room. The defrost frequency and performance are critical to heat pump efficiency. Undersized heat pumps will need to defrost frequently in low ambient temperatures, reducing the system’s ability to reach and maintain set point. If the defrost cycle operates too frequently or if it does not operate often enough, it will provide insufficient heating, and heat pump operation will be compromised. The defrost cycle control is either: • a time-temperature defrost starting and stopping at preset times (30-, 60- or 90-minute intervals); or • on-demand defrost, which is usually more efficient because it operates only when it detects frost build-up on the outdoor coil by monitoring air and coil temperature, outdoor airflow, pressure differential across the coil and refrigerant pressure. Systems that include a dry-coil defrost cycle briefly run the outdoor fan at maximum speed before the system starts to heat again, to remove any water that may still be on the coil fins and would immediately refreeze. The defrost frequency and performance are critical to heat pump efficiency. Environment, Climate and Efficiency The Climate and environmental factors also matter. Undersized heat pumps will need to defrost frequently in low ambient temperatures, reducing the system’s ability to reach and maintain set point. If the defrost cycle operates too frequently or if it does not operate often enough, it will not provide sufficient heating, and heat pump operation will be compromised. Environment is also a factor, in geothermal (such as Rotorua) or coastal areas (salty atmosphere ), the outside unit will need have suitable protection against corrosion. You can also run the unit more efficiently by setting the unit at a constant temperature that is not too hot or too cold, the unit will use less energy this way. Also letting the unit build up to the desired temperature also helps reducing the energy use, a heat pump soon heats up a room, but if you want a warm cosy home when you walk in the door after work, you can always use the timer settings which every brand, make and model have to set it to automatically turn on at a specific time each day. Installation The correct location and installation of both outdoor and indoor units is crucial for the most efficient performance. Consider noise and air flow. Locating the unit close to where you sit can mean the constant airflow may become irritating to you when sat watching TV. There are a number of different styles of indoor units, the most popular is the Split Hi Wall units (you can also get outdoor units that can run multiple indoor units). But if you want a heat pump in a bedroom with limited height such as a loft room, or you want your wall space for Artwork or shelving, then you may want to look at a floor mounted indoor unit. Do you want no unites on the walls? Then look at a ducted system. Finally how much does a Heat Pump cost? When it comes to buying anything, we always want the best price possible, and there are a lot of different prices ranges from the various manufacturers of Heat Pumps. Not all heat pumps are created equal, this is where spending some time researching and comparing systems will benefit you. Prices will range from size and also the features you can get, so remember that if a more energy efficient model is slightly more than the budget range, it will save you money in the long run. Use the tool here to compare models & sizes, because its not the initial outlay that you only have to think about, its your power bills at the end of each month that are more important.

By Team JSR Living during summer can be easy or hard at the same time. The weather can become super-hot, sweaty, and uncomfortable living conditions at this time. Hamilton and the whole Waikato region have beautiful long summers that can rise in temperature rapidly to as high as 24 °C and low as 15 °C. So we all retreat to our brilliant & dazzling air conditioner in our homes after being overwhelmed by the heat daily. Thank goodness for technology, we can live and breathe under cool air provided by the modern air conditioner (A/C). It’s a Kiwi family’s relaxation from the endless heatwave of warm air during the long summer days. Of course, the downside of having an air conditioner in your home is that it has to work super hard during the summer. It will skyrocket your energy bill without having you know it has risen. Most energy consumption occurs during midday, as temperature peaks at this time. However, there are valuable tips to help you reduce your energy bills over the course of summer. Apply these 6 tips to help you and your family to stay cool and still keep the A/C bills low. 1. Turn OFF your A/C during the night when sleeping As simple as this tip is clear as night, it’s one of the most cost-effective tips. Run your A/C throughout the day and turn it off at night. Why must you ask? The answer is simple; the evening air is normally cooler, so utilize this tip by turning off the A/C and fully opening the windows to let the cool breeze in and cool your house. For comfortable sleeping, your body doesn’t require the A/C to operate at a similar temperature as it does the whole day. So have sweet dreams while making massive energy savings. Turn off A/C at night 2. Remote Thermostats and Timers – Set and Save Every degree matters when you are trying to reduce your air conditioning bill over the summer. One of the ways you can reduce energy consumption is by setting your thermostat at a relaxing temperature that won’t force your A/C to work extremely hard, but still allow you to enjoy the benefits of it. We recommend setting your thermostat to around 22 °C and 24 °C. Do note the more you can drop a single degree of cooling, the more you’ll save on your electricity bill. So make sure to never over cool your home during summer. In fact, if you set your A/C unit one degree warmer, you can cut your electricity costs up to by a whopping 10%! To measure the right temperature, set your thermostat no less than 8 degrees off the outdoor temperature. For instance, if it’s 28 °C outdoors, aim for 20 °C or 19 °C. To maximise the energy reduction, use a thermostat with a built-in timer, so you also can set up hours of operation and temperature set up for the best energy performance. It’s only a one-time to properly set up a thermostat. But once it is done, you can set, forget, and save lots of money! Set thermostat one time, forget and save! 3.  Shade The Home, and Close Out The Sun Close out the sun in your home to keep your home cooler. It will make your air conditioning not work as hard as it would need if the sun is exposed in the house and reduce your electricity bill massively. During New Zealand summer, you can’t turn off the sun, but you can add shades to reduce the sun exposure. To add some shades to your home, consider blinds, curtains, and drapes and close them. Whether you’re using wooden or Venetian blinds, roller blinds, indoor shutter blinds, lined curtains, or any other shades, keep that sunshine outside where it belongs. For windows facing the sun, use light coloured backings for blinds and curtains, as it will deflect the sun rays as well. By adding these shades mentioned above, they’ll reduce the hot humid air and keep the sun rays out, which allows your A/C to run throughout the day at the desired temperature. Excessive heat can be dramatically reduced if your windows are installed with a strong protection cover. Tinted windows can prevent some heat as well. Want to prevent excessive heat from coming into the home and reduce electricity bills naturally? Plant trees, vines, shrubs that can act as a defensive barrier of shades around the property. Block excessive heat and reduce A/C costs 4. Turn OFF Electronic Devices that Trigger heat Gaming consoles, computers, lamps, kitchen ovens are all essential home items that generate a lot of heat, which forces the A/C to work harder to keep the temperature under control. Only use them when necessary and turn them off. You’ll save costs on your A/C usage right away! What can you do to reduce heat with these appliances? For computers, laptops, and gaming consoles, you could use air cooling fans to reduce heat in the home. Or consider having a conversation with your family members about it. For cooking, try having a BBQ outdoor for dinner, enjoy a salad or meals that require little cooking at all. Your home stove can heat your living room and add to your electricity bill. Reduce electronic usage and save! 5. Keep It Clean to Reduce Costs Clean your air conditioning regularly from dust and grime, which impacts the A/C efficiency when you don’t clean it. Test all units and clean them thoroughly, replace the filter or clean it as needed. Dirty filters can increase energy consumption and higher costs. Have your air conditioner or heat pump serviced by a professional at least every year. Clean A/C from inside and save! 6.  Upgrade to an Energy-Efficient A/C to save costs in the long run If you think your electricity bill is going through the roof due to your air conditioner, then it’s time to invest in an energy-saving one. Only do this if this is the only last option you have left. Talk to our qualified A/C installers to find you the right one.

Think cool drinks peppered with ice cubes, a cold cloth applied to your forehead of the back of your neck, a bowl of cool water to dip your feet in, and dressing appropriately for the season. 2: Close The Curtains On a lovely sunny day, it is nice to have the sun streaming into the house. But, that means the heat is streaming in too. If you strategically leave some curtains closed, you block the heat from entering the house. You don’t need it to look like a cave, but just choose to block the windows that let in the most direct sunlight. 3: Ice Fan Fans can help to cool the air, but can take some time to be effective. Supercharge your fan’s efforts by putting a tray of ice or a bowl of icy water in front of them. 4: Choose Cotton Cotton is a lovely, breathable fabric. If you choose cotton sheets over other synthetic materials, you will feel cooler in bed at night. It is also moisture-wicking, so pulls sweat away from your body. 5: Ditch The Oven Sometimes there is nothing nicer than a roast meal, but the oven can make the temperature in your house rise significantly. Skip the oven and maybe use the BBQ instead. Or, you could even elect to use a slow cooker which generates very little heat. 6: Turn Off The Tech Devices are awfully convenient, but they do generate a lot of heat when used. Make sure everything is switched off when you head to bed, and try to minimise the use of devices during the day. Lightbulbs are also culprits for generating heat, so enjoy the extended summer evenings without turning them on. 7: Use Your Heat Pump It may sound counterintuitive to use your HEAT pump when you want to eliminate the hot air in your house! But, heat pumps also have a cooling function. By simply altering the mode on your heat pump, you can use it as an air conditioner, blowing refreshing cool air through your home.

Fire Service Marlborough fire safety officer Lewis Jones, who investigated the blaze, said he suspected there had been a malfunction in the heat pump’s internal fan motor, which caused it to overheat and catch fire. The fan was on, which helped spread flames quickly, Mr Jones said. “As opposed to smouldering, it got involved reasonably quickly into a full-blown fire in the unit.” The fire spread through ducting into the wall, he said. Meryl and Peter Pentchev were woken by a smoke alarm early on Friday morning and saw flames coming from the heat pump in the living room of their Weld St house. Mr Jones said fires started by heat pumps were unusual, but not uncommon. The heat pump was about 10 years old, but there was no history of how the machine was maintained before the Pentchevs bought the home in September. “What has caused the malfunction will remain a mystery,” he said. “It’s like any engine. A bearing can get tight or it can get choked up with dust and cause resistance and make them work harder. “People can still be confident that heat pumps are a good unit, but it proves that they have to be maintained and serviced.” Three independent electrical experts helped with the investigation, Mr Jones said. Cuddon refrigeration and airconditioning manager Neville Patchett said he was surprised at the findings. Mr Patchett did not recall any major problems with heat pumps in 20 years, and incidents like the Pentchevs were rare, he said. As long as people kept filters clean and rubbish clear of the outdoor unit, there was no reason for problems, he said. Cleaning filters enabled better air flow and improved efficiency, he said. If people looked after their heat pump, it should not need servicing. TIPS FOR LOOKING AFTER A HEAT PUMP Clean your heat-pump filters twice a year. Filters can be found by opening the front panel of the unit. Keep rubbish away from the outdoor unit of the heat pump. Heat pumps can be serviced, but this needs to be done by a professional. Units usually need to be serviced only when there is a problem.

By Team JSR • 2022-02-21 • 4 min read Why Autumn Is Important for Your Heating System and Air Conditioning? It might be easy to ignore your heating system and air conditioner when working efficiently. But you may regret it for not maintaining them. By Team JSR It might be easy to ignore your heating system and air conditioner when working efficiently. But as soon as something breaks, you will regret for not keeping your heating systems or A/C maintained. As a result, you may have to get expensive repairs to get them running normally. As the weather starts to cool down during Autumn, it’s the best time to check your heating system before using them in winter. Never wait to maintain your heating system on the first day of winter when you find out it isn’t working. Avoid these problems as soon as they are found, or they’ll become prevalent. You’ll save thousands on repairs from regular maintenance. The great thing about doing maintenance is that both of your heating and air conditioner systems can be inspected at the same time. Even though you may not be using your A/C for a while, it should be inspected twice a year. A/C technician inspecting the performance of the A/C Regular maintenance is one of the best investments you can make for your A/C. It allows the technicians to see the current condition of your air conditioning.Here are a few benefits for maintaining A/C: Increased energy efficiency Improved airflow quality Better cooling output Preventing damage or worn-out crucial parts Reduced electricity bill Less A/C breakdowns or problems You may think your A/C system is functioning at first, but there is a chance the A/C technician may discover an issue that will only get worse overtime. Repairing small issues can avoid future breakdowns, keeping your A/C operating efficiently. When you get your A/C maintained, you’ll save thousands of dollars in damages and monthly electricity bills. A/C’s parts such as filters, coils, and fins need regular maintenance to function efficiently. If not properly cared for, A/C’s parts can deteriorate over time. Additionally, avoiding essential maintenance decreases the performance of the A/C while steadily increasing the energy consumption. When heating your home, unmaintained A/C will add more costs to your electricity bills as heating consumes more energy. According to Genesis Energy, if you run the A/C with 6 kilowatts of power, up to 6 hours a day for six months, it will cost $400 per year to operate. No matter what heating system you have in your home, you can still make huge savings and enjoy the benefits by maintaining your A/C. Need your A/C an inspection, cleaning, tune-up, or repair? JSR and its team are trusted air conditioning specialists in Waikato, providing consultation, maintenance, and installation for A/C systems.

Well-maintained on-farm refrigeration systems are crucial to maintain their efficiency and minimise risks to staff, stock and food safety. By Team JSR In this article, we will be talking about why it is important to regularly maintain and look after on-farm refrigeration systems. Energy-Efficiency for farm refrigeration Electrical costs are at the highest levels when fruit and vegetables are operated intensively during the summer of the year. To increase savings on energy consumption, improve the energy efficiency of refrigeration systems. This can be achieved by: Precool fruits and vegetables with cold water before putting them in refrigeration. Upgrading insulation of the refrigeration and storage areas. Making sure no infiltration and warm air is flowing through the doors, cracks, or unseeable openings. Regular maintenance and servicing of refrigeration equipment. Installing energy-efficient compressors, heat exchangers, and refrigerants.Preventing refrigerant leakages. Regular Refrigeration Maintenance improves Milk Quality Milk cooling impacts the quality of your milk. The faster you have milked from the farm, the higher the quality of your milk is. To cool your milk at the highest quality, you need to make sure your milk cooling system is up-to-date. Vat Refrigeration Vat Refrigeration Vat Refrigeration with direct expansion tanks, the refrigerants are pumped up into the evaporators (also known as jackets or dimple plates) inside the surfaces of the milk tank.Refrigerants enlarge as it consumes heat from the milk, pumped out of the evaporators, shrinks, then forced into the heat transfer (condenser). To cool hot refrigerant, air or water is flows through the heat transfer fins. The cooled gas compresses into a liquid and is pumped back into the evaporators around the milk to restart the phase again. However, direct expansion tanks have many disadvantages. One being maximum power being utilized during and after milk. On average, direct expansion use power at its maximum rate. If your refrigeration is using a large power supply, there might be problems in certain areas of weak power supply. If your Vat Refrigeration with direct expansion is being pressurised, they require a skilled technician for maintenance. Need consultation from a skilled technician? Get in touch with our team at JSR. Further Cooling Systems for Milk Cooling New highly advanced refrigeration systems that have scroll compressors are 15% to 20% more effective than regular reciprocating compressor systems. In addition, a wide variety of advanced refrigeration systems are available to increase efficiency and decreasing energy bills. If you aren’t already, consider using these options for further milk cooling: Cooling Towers Cooling towers are very efficient at cooling water in lower humidity areas, as you can cool water within 5 °C. Another benefit of cooling towers is that they can cool a large quantity of water overnight, usually 4½ times the quantity of the daily milk yield. Ice Banks Ice banks produce ice and evaporator coils using night rate power. Instead of just adding water, the ice is added to chill water for pre-cooling. From pre-cooler, the warm water flows to the top of the ice bank and the ice runs through to cool the water.The ice banks are high maintenance refrigeration system than other refrigeration systems. They are not energy efficient and consume similar energy as direct expansion vat. Ice banks might save energy if night rate electricity apply. However, one huge advantage of ice banks is that they take less space than storage of chilled water. Snap chillers This refrigeration option uses glycol systems to cool water with food grade glycol. Glycol systems use a small amount of fluid and produce chilled fluids on request (usually during the milking process). The Snap chiller was developed to chill milk at 4 °C. They will require an expensive, bigger compressor compared to an in-vat system. Note: This system is a high-priced capital expense and is recommended for farmers with large capital expenditures. Thermal stores Thermal storage chills water during the off season and stores chilled water in a large, insulated storage tank (one whole day milking). This refrigeration consumes more energy compared to a direct expansion tank. Although, thermal storage has its advantages like installation and maintenance processes. Vat wraps Save 15% to 25% cooling costs using saving vat wraps. Although, only 20% of New Zealand dairy farms use this refrigeration system. It does come with many benefits, such as the ability to insulate your milk from external temperatures and climates. Vat wraps also prevent milk from heating, which decreases your electricity costs from refrigeration units. To fully utilize vat wraps strengths, it depends on where your farm is located in New Zealand, and whether your vat is placed inside or outside. Need help maintaining your farm refrigeration system?

By Team JSR • 2020-02-11 • 4 min read (0800 577 722) Saving You Money Your heat pump or air conditioning system will work very hard in your home. They keep you warm in winter and cool in summer. In order to do that, they funnel a lot of air through their systems. During that process, the filters pick up a lot of particles from the atmosphere. Quite easily, the filters and coils can become clogged. Unless these are cleaned and the rest of the components are serviced, then your system will end up working harder than it needs to. Regularly servicing the system will mean that it can continue to perform as per the manufacturer’s specifications. Without regular servicing and maintenance, the equipment will have to work harder to maintain the desired comfort level. That could mean more expensive energy bills and the failure of certain parts earlier than they should. Maintenance protects your investment and ensures the long life of your system. Minimises Costly Repairs Many people don’t like the thought of having to pay for a service. But, let us ask you this question… would you rather pay the nominal fee for a service or have to pay to replace your whole heat pump or air conditioning system? Just as we thought, the small service fee is much more attractive! Our service engineers are trained to be proactive in highlighting the possible repair work needed to avoid equipment failure or breakdown in the future. This prevents the need for costly repairs down the track or needing a whole new system. Decreases Health Issues Dust is the enemy of anyone with allergies or respiratory issues. You could keep your home as clean as humanly possible, but if your heat pump or air conditioning unit is not serviced regularly, then the dust will keep cycling through the air. But, dust is not even the worst of it. Heat pump and air conditioning systems work by transferring air, heating or cooling it as needed. In order to do that, the air is drawn into the system to be fed back out at the desired temperature. That means, everything that is floating around in that air is drawn into the system too. It can include dust and grime, but also germs, bacteria and other airborne pathogens. Those then get distributed into the air in your home unless the system is serviced. A well maintainted system is a clean and healthy one, protecting the health of everyone within the home or workplace. How Often Should You Service? It is recommended that your heat pump or air conditioning system is serviced annually. During a service, the qualified technician will clean and flush the system, check all of the components, alert you or any repairs needed and carry out the repairs if instructed to. Remember, that after a year, the efficiency of your system could have reduced by as much as 50% depending on your outdoor air conditions. It can mean increased power consumption, loss of cooling and heating capacity, increased chance of system failure, and the increased possibility of air contamination. To prevent all of this from happening at your place, get in touch with us here at JSR to arrange your next preventative maintenance service. Contact JSR Refrigeration and Air Conditioning Today!

Cooking, cleaning, showering, and drying washing can all contribute to the levels of moisture created. In fact, it generates about 12L of moisture on a daily basis! And then you add in the cold weather. The cold weather is notorious for causing further dampness in your home. Poor insulation, drafts and condensation are all culprits for creating extra moisture. And we all know that moisture is one of the main ways that mould can grow. Mould is a dangerous toxin. It can impact your family’s health and leave you feeling less than great, so you want to minimise the chance of it forming. A well-ventilated home also clears away stale and unpleasant odours that you don’t want lingering around! Breathe Easily In A Dry Allergen-Free Home The air in your home can get polluted simply by living in it. If you don’t then replace that polluted air with fresh, your family could be breathing in any number of toxins. Dust mites, mould particles, and dampness can all contribute to poor health. The risk is even higher if you have someone who suffers from breathing difficulties or allergies. Good ventilation is essential for maintaining good air quality. Ventilation systems are beneficial in all homes but are especially effective in newer builds. With higher levels of insulation and double glazing, the stale air gets trapped in your home for longer. Luckily, a ventilation system can constantly cycle fresh air from outside to inside. This will allow your family to breathe easier in a dry and allergen-free home! Ventilation Systems Deliver Free Heat! Winter is cold! So, that means you will need to heat your home to ward away the chilly weather. That process can become expensive, regardless of which heating options you have available. So, you will be excited to know that ventilation systems can deliver free heat into your home! The job of a ventilation system is to move air around your home so that there is always a fresh source available. They use the space in the roof cavity to operate. So, that means they can push the warm air from the roof throughout the rest of your house. While a ventilation system does not work as a standalone heating option, it definitely contributes to keeping your home warmer. Heat loss is minimised and you get to enjoy a warm and healthy home! Oh, and on the flip side, it can also work to cool your home in summer. Would you like to know more about how you can get a ventilation system installed at your place?

The ridge becomes slow moving over the North Island during the weekend, as a cold front spreads north across the South Island.” If you don’t have a heat pump installed, click here to check out our latest special offer and give us a call on Free Phone: 0800 JSR RAC (0800 577 722) (and the list below will also come in handy in the future.) If you are lucky to already have one installed these next steps should help you navigate the oncoming winter months. Getting the most out of your Heat Pump this Winter 1. Using the control units function settings. Well when it comes to setting the temperature the best thing to do is not ramp it up to the highest setting to heat up your room quickly. The best way is to utilise the setting controls that come on the remote. (or if you are tech savy what about the app’s that you can set on your phone!) Set your clock up correctly and then set up the timer to turn on 15 minutes before you step out your warm cocoon of blankets. At a reasonable temperature (The recommended temperature is 18ºC or 20ºC for children, or the elderly, and 16ºC for bedrooms overnight). 2. Maintenance, do I really need it? When it comes to this question, most people who own their own properties will probably forget about this side of things, where as Rental and Commercial properties will come under regulations that cover this, but the short answer is YES, if you neglect the units (indoors and out) then when you really want them to perform, you may find they fail to deliver and will cost you a bigger repair bill. 3. Keeping the unit maintained. So you can do one of two things – DIY (do it yourself) OR give JSR Refrigeration & Air Conditioning a call on Free Phone: 0800 JSR RAC (0800 577 722) and one of our service technicians will come out and service it for you. DIY (yes I am being nice and giving you free tips, but why would you want to spend time cleaning when we can do it for you at the price above?) Every three months remove the filter from the indoor unit and give it a good vacuum. Be careful not to damage them and replace the correct way. On the outdoor unit to check that its not become overgrown by your garden (or weeds if its anything like my garden!) and clear of any debris. (a soft hand brush is good for this) Inspect for corrosion of the unit and any loose panels (keep those pesky rodents from making a home in it!) – or contact JSR as I suggested above, and spend your time doing something more interesting. The often forgotten element, the Outdoor Unit. Heat Pumps should be elevated 4 to 8 inches above ground level to allow for proper drainage, if you think your outdoor unit is not raised sufficiently, contact our Service Department. The outside unit needs good airflow, as much winter sun and as little frost as possible. They need to be protected from elements that might cause corrosion, such as sea spray. Keeping the running costs down. Heat pumps are efficient in cold weather compared to other electricity powered heating units,but the heat pump’s running costs depend on how long you use it and its energy output. ( It also depends on where you live – some heat pumps do not perform as well in the cold, so if you regularly get below -5ºC outside, you need to choose one that will perform well, or the unit will spend excess energy defrosting).You can check out your units running costs by going to energywise.govt.nz and entering the fields on their calculator. Other useful tips for keeping the you and the house warm are: Close doors and curtains to keep the heat in as the sun goes down (or when you get home if you work all day like me) and use draught stoppers (tape and the sausage type that you place in or on the door) on your outside doors. I actually have this type on ours as we have porches to stop the rain. Winter ideas to keep the drafts out How to make a Double Door Draught stopper (click for instructions) If you can, get your house insulated. The better insulated your home, the better it will hold the heat and the more energy efficient the heat pump will be. Make sure your windows are sealing correctly, use that draft tape on them if needed. Slippers – yes keeping your tootsies warm will help keep you feeling toasty!

While heat pumps are well-known for their ability to keep us cosy during the chilly season, they offer an additional benefit that often goes unnoticed – contributing to healthier indoor air quality. In this blog, we will explore how heat pumps positively impact indoor air quality and promote winter wellness in New Zealand homes. The Role of Indoor Air Quality in Winter Health: During winter, kiwis spend more time indoors, leading to increased exposure to indoor air pollutants. These pollutants can come from various sources, such as dust, mould, pet dander, cooking, and even certain household products. When we breathe poor air quality, it can negatively impact our health. Allergies, respiratory problems and even exacerbate symptoms of asthma are some of the conditions we may face. Heat Pumps: Purifiers of Indoor Air Heat pumps function by circulating air throughout your home, not just by heating it. This air circulation plays a vital role in maintaining indoor air quality. As the heat pump pulls in outdoor air, it filters it through its built-in air filters, capturing dust, allergens, and other particles in the process. The purified air is then distributed evenly throughout your living space, ensuring you, your family and friends can breathe in cleaner, healthier air during winter. Filtration Efficiency Matters When choosing a heat pump, consider its filtration efficiency. High-quality heat pumps are equipped with advanced filters capable of trapping even the smallest airborne particles, such as pollen, bacteria, and volatile organic compounds (VOCs). These efficient filters significantly reduce the presence of airborne allergens and pollutants, contributing to a healthier indoor environment. Say Goodbye to Dampness and Mould According to Stats NZ, Dampness and mould are common issues during New Zealand winters, especially in regions such as Northland, Auckland and the Waikato with higher humidity levels. Heat pumps play a crucial role in controlling indoor humidity, reducing the risk of mould growth. By maintaining balanced moisture levels, heat pumps create an adverse environment for mould to thrive, helping you avoid potential health hazards associated with mould exposure. Enhanced Ventilation for Fresh Air Modern heat pump models often come with ventilation features, allowing you to introduce fresh outdoor air into your home while maintaining a comfortable indoor temperature. This ventilation helps to flush out stale air and ensures a constant supply of fresh air, promoting a healthier and more rejuvenating living space. Reducing Household Allergens New Zealand homes can harbour various allergens, including dust mites, pet dander, and pollen. As heat pumps filter the air, they effectively reduce the presence of these allergens, providing relief to allergy sufferers and allowing everyone in the household to breathe easier. Overall As we embrace winter in New Zealand, prioritising indoor air quality is essential for maintaining our well-being and overall health. Heat pumps act as efficient purifiers of indoor air, reducing airborne pollutants, controlling humidity, and preventing the growth of mould. By investing in a high-quality heat pump and ensuring regular maintenance, you can create a healthier indoor environment for you and your loved ones, promoting winter wellness and enjoying the season to its fullest. Stay warm, stay healthy, and breathe easy this winter with the help of a reliable heat pump in your home. Best heatpumps to improve indoor air quality your home?

But have you also added heating and cooling system in your Spring to-do list? It’s never too late to get your heat pump or your A/C ready for the hot, humid Hamilton summer that is about to arrive in the coming months. We’ve gathered a Spring HVAC to-do list for your home in Hamilton or in the Waikato region, so your home can stay cool, feel cosy, healthy, and efficient throughout summer. 1. Change Your Air Filters Have you spent more time in your home compared to this last year and years before? Chances are your heat pump’s air filters have likely collected dirt, dust, pollen, and other pollutant from the great winter. The good news from this is that they’ve done their job! But the air filters have to be replaced every six months or once a year depending on the usage and the manufacturer specifications. Air filters clogged with dirt are probable to the loss of filtration properties and cause your furnace, heat pump, or your air conditioner to work harder than it should when the air is pulling into the unit. Purchasing your own air filter is a DIY solution and economical way of improving indoor air quality without contrarily affecting your energy costs. 2. Wash off the loose debris From Outside HVAC Equipment If you have a central ducted A/C or heat pump systems that incorporate a build in outdoor compressor, it’s important to clean the surrounding space. Leaves, stems, rubbish, raw materials, child’s toys, and anything that you keep in your backyard can lead to issues when you are required to use the cooling systems at the beginning of this Spring. Make sure to have a clear space around 12 to 18 inches of space outside the unit, including cutting overgrown grass, weeds, or plants around your outdoor compressor. 3. Check your thermostat if it’s functioning normally Inspect your thermostat if it’s operating as it should. Make sure to check if it’s displaying the accurate temperature inside your home. If this issue keeps occurring, consider replacing or upgrading your thermostat with a smart thermostat. You deserve ease and comfort! With these small, smart thermostat handheld devices, you’re not just getting smarter home management comfort – you’re also saving on your energy bill. 4.
