Cold room service
Freezer Room Repairs in Sandton
Freezer rooms operate at sub-zero temperatures, so a fault can begin defrosting stock far faster than a cold room failure. We repair walk-in freezers and freezer rooms across Sandton and greater Johannesburg.
Professional service
Freezer room repairs involve refrigeration systems working at lower temperatures, where defrost performance is critical. We repair compressors, condensers, evaporators with defrost heaters and fans, refrigerant leaks, defrost controllers and timers, door seals and heaters, and electrical supply. Ice build-up is a common symptom with several distinct causes that must be diagnosed correctly rather than just defrosted.
Common problems we attend
- Temperature rising above -18°C
- Heavy ice build-up on evaporator
- Compressor not running
- Defrost cycle not working
- Refrigerant leak
- Door frozen shut or seal failed
