We repair both, plus the refrigeration circuit that keeps them cold. We serve Randburg and the wider North-Western corridor of Johannesburg, with an average emergency arrival time of approximately 35 minutes.

Professional Diagnostic Process
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.
