Refrigeration Container Maintenance

​

  • 24/7 On-Call Response:
    Immediate attendance for breakdowns and temperature-critical issues. Our technicians carry the tools, parts, and refrigerant to get your containers back online fast - not just diagnose and leave.

  • Tier 1 Service Agreement:
    Guaranteed response priority during high-demand periods. Tier 1 clients like Dawson Group get front-of-queue service and direct technician allocation - meaning your call doesn’t sit in the queue when others do.

  • Preventative Maintenance Programs:
    Scheduled inspections designed around your usage cycles. We check compressor health, pressure balance, electrical integrity, defrost systems, and door seals - ensuring containers hold temperature efficiently and meet compliance.

  • Detailed Service Reporting:
    Every visit includes a technical report with readings, component checks, and recommendations so you can track performance, plan maintenance, and meet audit or client documentation needs.

  • Stocked Spare Parts & Rapid Turnaround:
    Our vehicles and local depot stock common container refrigeration parts (controllers, sensors, TX valves, contactors, etc.), reducing downtime and the need for repeat visits.

  • System Performance Optimisation:
    Beyond fixing faults, we monitor performance data to improve efficiency - identifying systems that are overworking, short-cycling, or showing early signs of refrigerant imbalance.

  • Custom Service Scheduling:
    Maintenance aligned to your operational windows — we work around your logistics schedule so your containers are serviced when idle, not when needed.

  • Compliance and Documentation:
    Maintenance aligned with NZ regulatory and manufacturer standards (including leak testing and certification). Full service history retained for audit and insurance purposes.
