Walk-In Freezer Repairs Johannesburg
Walk-in freezers demand reliable defrost and tight door seals — the two systems that fail most often and cause the most stock loss. We repair both, plus the refrigeration circuit that keeps them cold.
- [01]Ice build-up around the door
- [02]Floor frost or slip hazard
- [03]Temperature above -18°C
- [04]Defrost not clearing the coil
- [01]Defrost heater failure
- [02]Drain line freeze
- [03]Door seal or strip curtain damage
- [04]Refrigerant undercharge
We test every defrost heater, the drain line, the door seal and the refrigerant charge — because in a walk-in freezer, any one of them failing produces the same symptom.
We restore defrost effectiveness first, then refrigeration capacity, ensuring the freezer returns to and holds sub-zero temperature reliably.
Why does my walk-in freezer keep icing up?
Almost always a defrost or door-seal fault. We identify which before any refrigerant work.
The floor is frosting — is that dangerous?
It is a slip and stock hazard and usually indicates a door or defrost problem that we can repair.
How often should a walk-in freezer be serviced?
Planned maintenance every 3–6 months prevents most ice and defrost failures.
