Aircon Repairs in Randburg
Unit blowing warm air, dripping on the wall or flashing an error code? ARS does aircon repairs in Randburg on site, for homes, townhouse complexes, offices and workshops, on all makes and models.
Randburg came into being in 1959 and ran as its own town before its administration moved to the City of Johannesburg in the late 1990s. It covers dozens of suburbs, from Blairgowrie and Bordeaux in the south, through Ferndale and Robindale, up to Fontainebleau, Randpark Ridge and Northriding.
Most aircons here are wall-mounted splits in homes and complexes, with cassettes and splits in offices and showrooms. When one fails, the fix almost always happens where it's installed, so our aircon repairs in Randburg are done at your property, not in a workshop.
How Aircon Repairs in Randburg Work
Describe the fault
Call or send the quote form with the make, model if you have it, and what the unit is doing. Error codes help a lot.
On-site diagnosis
We test the electrics, control board, fans, pressures and drain to find the actual cause, not just the symptom.
Clear options
You get the cause in plain language and the cost of fixing it. If repair isn't sensible on an old unit, we say so.
Fix and test
Once you approve, we repair it and run the unit to confirm it's cooling, heating and draining as it should.
Homes, Complexes and Workplaces Across Randburg
Randburg's housing is a mix. There are freestanding family homes on leafy streets, townhouses in secure complexes and newer cluster developments. In complexes, outdoor units are often squeezed into narrow side passages or onto shared walls, which starves them of airflow on hot days and makes them noisy. Sometimes the best repair is moving the condenser, which needs body corporate approval; our aircon relocation page explains how that works.
On the commercial side, Ferndale has office space along Bram Fischer Drive and Brightwater Commons, and Cresta Shopping Centre is one of the area's main retail hubs. Strijdom Park is a commercial and light-industrial area with a big motor trade presence. Workshop dust, overspray and exhaust fumes coat outdoor coils fast there, and a clogged coil is one of the most common reasons a unit trips or stops cooling.
Further south, we also look after homes in Northcliff. For neighbouring areas, see our pages for Roodepoort, Fourways and Sandton.
Aircon Faults We See Often in Randburg
Most repair calls trace back to one of these.
- Blowing air but not cooling. Often a refrigerant leak, a failed outdoor fan or a dead capacitor. Low gas always means a leak that needs finding before any regas.
- Water running down the wall. A blocked or badly sloped condensate drain, or a frozen coil that floods as it thaws.
- Breaker trips when the unit starts. Shorted components, a failing compressor or an undersized circuit. Our article on why an aircon keeps tripping the breaker explains the usual culprits.
- Dead or error-flashing after an outage. Surges when power returns after load shedding or a storm can damage the control board (PCB).
- Rattling or humming outdoor unit. Loose brackets, a worn fan motor or a condenser crammed into a tight passage.
- Ageing R22 units. R22 is being phased out, so major repairs on these older systems are often poor value compared with replacement.
Randburg Repair Questions
Yes. Let your body corporate or managing agent know we're coming if the outdoor unit is on a shared wall or roof, and make sure we can get to both the indoor and outdoor units. If the condenser needs to move, that usually requires the body corporate's approval first.
We work on all types, makes and models of split, cassette and ducted units. If your unit is still under warranty, check whether the manufacturer requires its own appointed agent to do the repair.
Refrigerant doesn't get used up, so a unit that's low has a leak. We find and repair the leak, pressure-test the system and then regas it with the correct refrigerant. Topping up without fixing the leak just wastes money.
It depends on the fault, the unit's age and the refrigerant it uses. A failed capacitor or fan on a reasonably young unit is usually worth fixing. A dead compressor on an old R22 unit often isn't. You'll get the numbers for both routes before deciding.
Yes. After-hours emergency call-outs can be booked any time of day or night, any day of the year. Call 0861 995 092 and describe the problem.
