JSR Refrigeration specializes in comprehensive refrigeration servicing and scheduled maintenance packages tailored to your business needs. We strongly recommend routine preventative checks to isolate worn components and fix potential issues before costly breakdowns or perishable stock loss occur.

Planned Preventative Maintenance Packages

Custom scheduled maintenance programs (monthly, quarterly, or bi-annually) designed for supermarkets, cold storage facilities, restaurants, and dairy farms. Routine checks keep systems running to full manufacturer specifications.

  • Extends equipment lifespan and prevents unexpected component failure
  • Reduces monthly electricity bills by maintaining peak heat transfer efficiency
  • Provides full service history logs for compliance and insurance protection

24 Hours & 7 Days Emergency Breakdown Repairs

Refrigeration failures don't wait for business hours. Our service vans are stocked with universal spare parts, compressors, fan motors, control boards, and refrigerants for immediate 24/7 dispatch across Hamilton & Waikato.

  • Rapid 24/7 response to protect food stock, milk vats, and chilled inventory
  • Experienced trade-certified technicians equipped for complex diagnostics
  • Temporary mobile chiller support available if major repairs are needed

Gas Leak Detection & Component Diagnostics

Refrigerant gas leaks cause cooling loss, compressor damage, and high utility bills. Our qualified technicians use electronic leak detectors and pressure testing to locate micro-leaks, seal pipework, and recharge gas safely.

  • Electronic halogen leak testing & nitrogen pressure testing
  • Compressor oil checks, expansion valve calibration, and coil cleaning
  • Compliance with NZ environmental refrigerant containment regulations

Energy Savings Audits & System Retrofits

The most cost-effective way to eliminate high power costs is by optimizing current equipment or retrofitting older units with energy-efficient Patton condensing units rated for up to 45°C ambient summer temperatures.

  • Comprehensive energy audits to identify power-hungry components
  • Retrofitting legacy systems (R22/R404A phase-out support)
  • Installation of high-efficiency condensers and EC variable-speed fans

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).
