No hot water at all
Controller, element and refrigerant circuit checks to separate a heat pump fault from a plumbing or geyser fault.
Heat Pump Repair in Randburg & Sandton
A heat pump that stops heating is an emergency in a family home, and Johannesburg winter mornings are unforgiving. We repair domestic and commercial heat pump geysers — controllers, sensors, fans, defrost faults and refrigerant loss — and get hot water back the same day wherever possible.
What this covers
Iced-up evaporator coils
Defrost cycle diagnosis, sensor replacement and airflow correction so the unit stops freezing itself solid.
Runs constantly, heats slowly
Gas charge, thermostat calibration and sizing assessment — often the unit is fine and the settings are not.
Error codes on the controller
Board-level diagnosis and genuine replacement controllers where the display is dead or unreadable.
Noisy fan or compressor
Bearing, mount and fan blade repairs before vibration damages the refrigerant lines.
Commercial hot water systems
Guesthouses, salons and estates with multi-unit banks kept running on priority response.
What it costs
Heat pump diagnosis carries the same fixed call-out fee as aircon work. Controllers and sensors are typically inexpensive; compressors and full regas jobs cost more and are quoted before we start.

Is it worth repairing an old heat pump?
Often yes — controllers, fans and sensors are the usual failures and they are far cheaper than a new unit. If the compressor has gone on a unit past ten years we will tell you honestly that replacement makes better financial sense.

We service the common South African brands including Kwikot, ITS, Alliance, Hisense and Midea, plus most imported units.
