Aircon repairs in Cape Town start with fault finding, not with a part. The same symptom — no cooling, a trip, a puddle — has several possible causes at very different prices, and nobody can tell you which one it is from a description.
What you can do is describe the symptom accurately, and get repair quotes from aircon technicians covering your suburb.
Send the brand, roughly how old the unit is, what it is doing and any error code on the display. That is enough to price a call-out.
Get Repair QuotesCommon Aircon Problems and What They Usually Mean
| Symptom | Usual causes | Where it lands on price |
|---|---|---|
| Aircon not cooling, blowing warm air | Low refrigerant from a leak, failed capacitor, dirty coils, compressor not starting | Low to very high |
| Aircon not heating | Reversing valve, sensor fault, or the unit is cooling-only | Moderate to high |
| Water leaking from the indoor unit | Blocked drain, dirty filter causing icing, unit out of level | Low |
| Aircon keeps switching off | Overheating condenser, low gas protection, PCB or sensor fault | Low to high |
| Aircon not turning on at all | Isolator, breaker, remote, PCB, transformer | Low to moderate |
| Aircon icing up | Restricted airflow, dirty filter or coil, low refrigerant | Low, unless it is a leak |
| Rattling, grinding or screeching | Fan bearing, loose blower wheel, debris, failing compressor | Low to high |
| Bad smell when running | Mould and biofilm on the coil and blower wheel | Low, cleaning rather than repair |
| Aircon compressor not working | Capacitor, contactor, overload, or the compressor itself | Cheap or terminal, nothing between |
| Outdoor fan not running | Fan motor, capacitor, relay | Moderate |
| Aircon remote not working | Batteries, IR emitter, receiver board | Low |
| Error code on the display | Brand-specific; narrows the fault considerably | Varies, but shortens diagnosis |
Read the error code off the display or count the flashes on the indoor unit before anyone arrives. Codes are brand-specific and they take a technician straight to the circuit at fault, which shortens the call-out you are paying for.
Refrigerant Is Not a Consumable
A sealed system does not use up gas. If a unit needed gas two summers ago and needs it again, it has a leak, and adding more refrigerant is renting the problem rather than fixing it. Anyone who offers to regas without a leak test is selling you a repeat visit.
Aircon Repair Costs in Cape Town
| Job | Indicative range | Notes |
|---|---|---|
| Call-out and fault finding | R450 – R950 | Often credited if the repair proceeds |
| Capacitor replacement | R850 – R2,200 | Common cause of a compressor that hums but will not start |
| Contactor or relay | R900 – R2,200 | Frequently paired with the capacitor |
| Temperature sensor or thermistor | R650 – R1,800 | Cheap part, diagnosis is the work |
| Indoor fan motor | R1,800 – R4,500 | Varies widely by brand availability |
| Outdoor fan motor | R2,200 – R5,500 | Includes blade and capacitor where needed |
| Control board (PCB) | R2,500 – R7,500 | Often the point where replacement is reconsidered |
| Blocked drain clearing | R650 – R1,600 | Frequently done alongside a service |
| Leak find, braze, vacuum and regas | R2,500 – R6,500 | Depends on where the leak is |
| Compressor replacement | R6,500 – R18,000 | On most domestic units, compare against a new system |
| After-hours or weekend surcharge | +R500 – R1,500 | Added to the job price, not instead of it |
Indicative Cape Town ranges, not a quotation. Brand, part availability, unit age and whether the unit sits at height all move the number. Older and imported brands frequently cost more in parts than the repair labour.

Compare Repair QuotesRepair or Replace?
- Under about 6 years. Repair. Capacitors, sensors, fan motors and boards are normal wear.
- 6 to 10 years. Judgement. A cheap electrical repair is worth doing; a compressor or a board on a tired unit usually is not.
- Over about 10 years, or an R22 unit. Price the replacement before authorising a major repair. R22 is phased out, the gas is expensive where it is available at all, and you are spending on a system with no future.
- Repair cost over roughly half a new installed system. Replace.
Emergency Aircon Repairs
Domestic aircon is a comfort failure, not an emergency, and after-hours rates reflect that. It is different where cooling is load-bearing: server rooms, restaurant kitchens, medical rooms and cold-sensitive stock. Say so in the request and contractors who carry after-hours capacity will respond accordingly.
Frequently Asked Questions
How much does an aircon repair cost in Cape Town?
Most domestic repairs land between R850 and R4,500 once the call-out and part are included. Electrical faults like capacitors and contactors sit at the cheap end, control boards and compressors at the expensive end.
Why is my aircon blowing warm air?
The usual causes are a refrigerant leak, a failed capacitor stopping the compressor, badly fouled coils, or the outdoor fan not running. All four present identically at the vent, which is why diagnosis comes before a price.
Is it worth repairing a 10-year-old aircon?
For a cheap electrical part, usually yes. For a compressor or a control board, price a replacement first — the repair often comes to half the cost of a new installed system with a fresh warranty.
My aircon is leaking water inside. Is that serious?
Usually not, and usually cheap. It is most often a blocked condensate drain or a filter so dirty that the coil iced up and then thawed. It becomes serious when the water has been running into a ceiling for weeks.
Does a dirty filter really matter?
Yes. Restricted airflow is behind a large share of call-outs: weak cooling, icing, water leaks and short cycling all trace back to it. Filters in most Cape Town homes want cleaning monthly through summer.
Can you repair my aircon today?
That depends on the contractor, not on us. Flag urgency in the request and contractors with same-day or after-hours capacity will say so when they quote.
