Same-day service On-site repair Call 072 686 0472
On-site repair and servicing for split and inverter air conditioners in homes, offices and businesses: not cooling, leaking, error codes, regassing and new installations.
Quick answer: The most common causes are dirty filters, a dirty outdoor unit, low refrigerant from a leak, a failed capacitor or fan motor, or an inverter board or compressor fault. Start by cleaning the indoor filters and checking that the outdoor unit is running and not blocked.
Local aircon pages: Pretoria, Centurion, Midrand, Kempton Park, Johannesburg. Every installation includes a free service six months later, and back-to-back installations start from R1,650.
Before you call, make sure the remote is set to cool mode (a snowflake icon) and not fan or dry mode, and that the temperature is set below the room temperature. Clean the indoor filters, and check the outdoor unit isn't blocked by plants or debris. If the aircon still blows warm air, it needs a technician.
Gauteng's hot summers and afternoon thunderstorms put aircons under pressure. Lightning and power surges are a common cause of damaged inverter boards. We can test surge-damaged units and give you a written report for your insurer.
This table shows the most likely Aircon faults, so you know what to expect before we arrive:
| Symptom | Most likely causes | What to check first |
|---|---|---|
| Blowing air but not cold | Dirty filters or coils; low gas from a leak; outdoor fan or capacitor; compressor | Clean the filters and check the outdoor fan is spinning |
| Water dripping from indoor unit | Blocked drain line; dirty filter causing the coil to ice up; unit not level | Check whether ice is forming on the indoor coil |
| Error code on display | Sensor, communication, inverter board or gas fault | Note the code and your brand and model |
| Won't turn on | Remote batteries; breaker tripped; control board; power supply | Replace the remote batteries and check the breaker |
| Bad smell | Mould or bacteria on the coils and filters | Book a deep clean and service |
| Very noisy | Loose panel, fan hitting something, worn fan motor bearings or compressor | Check for loose covers or debris near the outdoor fan |
| Outdoor unit not running | Capacitor; contactor; inverter board; wiring or surge damage | Check whether the outdoor fan hums without turning |
Quick answer: Service a home aircon once or twice a year, ideally before summer. Commercial units and aircons that run all day should be serviced every 3 to 6 months.
A service keeps the unit cooling well, lowers your electricity bill, prevents water leaks and bad smells, and catches small faults before they become expensive compressor repairs. You can also clean the indoor filters yourself every 2 to 4 weeks during heavy use.
An aircon is a sealed system, so it only runs low on gas if there's a leak. Regassing without finding and fixing the leak only works for a while before the problem returns. We test for leaks first, repair them, and then regas to the manufacturer's specification. See how we do it on our aircon regas page.
Quick answer: Every job starts with a flat R350 call-out fee. That includes getting to you, finding the aircon fault on site and a written quote. After that, the aircon repair price depends on the part and labour, and nothing happens until you approve it.
Filter cleaning, drain clearing and capacitor replacement are at the lower end. Leak repair with a regas, fan motors and inverter boards cost more. Compressor replacement is the most expensive, and on older units it's often better to replace the whole unit. For typical price ranges, see our appliance repair cost guide.
Split aircons usually last about 10 to 15 years with regular servicing. If an older unit needs a new compressor, or still uses the old R22 gas, replacing it with a modern inverter unit is often better value. Inverter units also use noticeably less electricity.
We take Aircon bookings Monday to Saturday, 07:30 to 17:30. Most aircon call-outs are seen the same day, depending on how busy our technicians are. Living in an estate? Send the gate procedure with your aircon booking and we'll sort out access.
Aircon repairs in all of these areas carry the same R350 call-out. Linked areas have their own local page.
We repair and service all major aircon brands, including Daikin, Midea, Hisense, KIC, Samsung and LG. Brand pages:
Every aircon repair starts with a flat R350 call-out fee. It includes the trip to you, testing the aircon on site and a written quote. The final cost depends on the fault, and you approve the quote before any work begins.
Usually the condensate drain line is blocked, or a dirty filter has made the indoor coil freeze and then drip as it melts. A service that clears the drain and cleans the coil normally fixes it.
Yes. We regas both R32 and R410a units, after finding and repairing the leak that caused the gas loss.
Yes. We supply and install inverter split units for homes and businesses, and replace old or inefficient units.
Yes. We service and repair commercial units, including multi-split and VRV/VRF systems, and offer planned maintenance for offices, shops and restaurants.
We cover Sandton, Bryanston, Fourways, Midrand, Kyalami, Waterfall, Pretoria East, Centurion, Randburg, Northcliff, Bedfordview, Edenvale and the surrounding suburbs, for the same R350 call-out fee.
Send your suburb, the aircon brand and what it's doing, and we'll offer the earliest slot.

The customer in Krugersdorp had an LG Inverter V split aircon where the indoor unit switched on and blew air, but the outdoor unit never came on, so the room wasn't getting cool. With no outdoor unit running, the compressor and outdoor fan never start, so all the indoor unit can do is move room-temperature air around. We opened up the outdoor unit and tested it, and traced the fault to the outdoor unit's PC board, the inverter control board that drives the compressor and fan. After the board repair, the outdoor unit started up and the aircon was cooling properly again. Tip: if your split aircon is blowing but not cooling, go outside and check whether the outdoor unit is running. If its fan isn't turning and it's silent, the problem is usually electrical, such as the outdoor PC board, a capacitor or the power supply to the unit, not gas.
This aircon in Krugersdorp had lost its gas and stopped cooling. The pipework runs high up the outside of a double-storey home, up to the indoor unit near the roofline, so the job needed long extension ladders, one technician working at the top and a second one holding the ladder steady at the bottom. Our technicians traced the leak to the liquid line, which had been installed in aluminium. Aluminium pipe and its joints are more prone to corrosion and cracking than copper, especially outdoors. We replaced the leaking aluminium line with proper copper pipe, pressure-tested the joints, vacuumed the system and regassed it. The aircon is now cooling at full strength again. Tip: if your aircon keeps needing gas, don't just keep topping it up. There's a leak somewhere, and on some installations the cause is aluminium pipework that should be replaced with copper.
The customer's aircon was struggling to cool the room. Our diagnosis showed the fan in the outdoor unit wasn't spinning. That fan blows air across the outdoor coil to get rid of the heat taken out of the room. Without it the aircon can't shed heat, so it runs inefficiently, barely cools and puts strain on the compressor. We replaced the outdoor fan motor, gave the aircon a full service and tested it cooling properly again. The customer was very happy. Tip: if your aircon blows but doesn't cool, look at the outdoor unit while it's running. If its fan isn't turning, switch the aircon off and call us, because running it like that can damage the compressor.
The aircon had stopped working and the indoor unit was showing E1. On Alliance splits, E1 can point to several faults: most often a communication problem between the indoor and outdoor units, but also the main control board, a temperature sensor or the wiring. Rather than guessing and swapping parts, we assessed it and found the communication cable itself was damaged, so the signal wasn't getting through. We replaced the cable, and the unit started working perfectly again, with no new boards and no new aircon. More on this code: what E1 means on an Alliance aircon.
The aircon was running but not cooling the room. On units like this, mounted high on a sunny wall, the outdoor coil collects a season's worth of dust and the indoor filters and coil clog up, so the system simply can't move heat out of the house. We gave it a full service: filters washed, indoor coil and fan cleaned, drain line flushed, outdoor unit washed down, and the gas pressures and electrical parts checked. With the airflow restored, it was cooling properly again. A yearly service before summer stops this happening in the first heatwave.
