We repair and install cold rooms across Gauteng: walk-in chillers and freezers for restaurants, butcheries, supermarkets, bakeries, florists, farms and other food businesses. The most common faults we fix are a cold room that won't hold temperature, an evaporator that ices up, a condensing unit that won't start or keeps tripping, refrigerant gas leaks, and faulty controllers, sensors, fans or door seals. We find the cause on site, give you a fixed price before any work, and repair it, often on the first visit. We also install new cold room refrigeration and service existing systems so they don't fail during a busy period. Call or WhatsApp 072 686 0472.
Cold rooms we work on
- Walk-in chillers for fresh produce, dairy, drinks and prepared food, typically kept between about 0 and 5 °C.
- Walk-in freezers for frozen meat, fish and stock, typically kept around −18 °C or colder.
- Butchery, bakery, restaurant, supermarket, florist and farm cold rooms, from small single-door rooms to larger rooms with more than one evaporator.
We work on cold rooms with all makes of condensing units, evaporators and controllers.
Common cold room faults we fix
- Not holding temperature. The room creeps up during the day or never reaches its set point. Common causes are a dirty or blocked condenser, low refrigerant from a leak, a failing compressor, an evaporator fan that has stopped, or a door that isn't sealing.
- Evaporator icing up. Ice building on the coil blocks the airflow, so the room warms up even though the system is running. Usually a defrost fault: a failed defrost heater, a faulty defrost sensor or timer, or a blocked or frozen drain line.
- Water or ice on the floor. Often a blocked drain, a drain line heater that has failed on a freezer, or a damaged door heater or seal letting in warm, damp air.
- Condensing unit not starting or tripping. Electrical faults such as a failed contactor, capacitor or overload, a high or low pressure switch cutting out, or a compressor fault.
- Refrigerant gas leaks. We find and repair the leak first, then pressure-test, vacuum and regas the system, so the gas stays in.
- Controller and alarm faults. Wrong readings, constant alarms or a controller that won't switch the system correctly, often a faulty probe or controller.
What to do while you wait
If your cold room is warming up, keep the door closed as much as possible, move the most sensitive stock to another fridge or freezer if you can, and check that nothing is blocking the evaporator fans inside or the condensing unit outside. Don't chip ice off the evaporator coil, because it is easy to puncture a pipe and cause a gas leak.
Cold room installation
We install cold room refrigeration for new and existing rooms: the condensing unit outside, the evaporator inside, the pipework, controls and drain. We size the system for the room, the stock you keep and the temperature you need, and position the condensing unit where it has enough airflow to reject heat. Tell us the room size, what you store and the temperature you need, and we will quote.
Servicing
A cold room works hard every day of the year. Regular servicing keeps it efficient and picks up problems before they cost you stock: cleaning the condenser and evaporator, checking the refrigerant pressures, testing the defrost system and drain, checking door seals and heaters, and testing the controller and alarms.

Frequently asked questions
Why is my cold room not getting cold enough?
The most common causes are a dirty or blocked condenser, low refrigerant from a gas leak, an evaporator that has iced up, a stopped evaporator fan, or a door that isn't sealing. We test the system on site to find which it is before quoting.
Why is my cold room evaporator icing up?
Usually a defrost problem: a failed defrost heater, a faulty defrost sensor or timer, or a blocked or frozen drain line. Ice on the coil blocks the airflow, so the room warms up even though the system is running.
Do you install new cold rooms?
Yes. We install cold room refrigeration across Gauteng, including the condensing unit, evaporator, pipework, controls and drain, sized for your room, your stock and the temperature you need.
Can you come out the same day?
In most cases, yes. A cold room that is warming up puts stock at risk, so call or WhatsApp 072 686 0472 and we will get a technician to you as soon as possible.
Do you service cold rooms?
Yes. A service covers cleaning the condenser and evaporator, checking refrigerant pressures, testing the defrost system, drain, door seals and heaters, and checking the controller and alarms.
