A well-installed aircon cools faster, runs quieter and lasts longer. We install wall split, under-ceiling, cassette and ducted systems in homes and businesses, and we size each one for the room it's going into.
A standard wall split installation starts from R2,500, with the unit bought separately. Under-ceiling units start from R3,800, cassettes from R4,500 and ducted systems from R5,500. The final price depends on the unit size, the distance between the indoor and outdoor units, wall access, brackets and drainage.

BTU (British Thermal Unit) is how much heat the aircon can remove. Rooms with lots of glass, afternoon sun, high ceilings or a poorly insulated roof need a bigger unit. Too small and it runs flat out without keeping up; too big and it switches on and off constantly, wasting power. We check this when we quote, so you only buy once.
| Room size | Suggested size |
|---|---|
|
Up to about 15 m² |
9,000 BTU |
|
About 15-25 m² |
12,000 BTU |
|
About 25-40 m² |
18,000 BTU |

A standard back-to-back wall split usually takes 3 to 5 hours. Long pipe runs, double-storey walls or tricky access can take most of a day. Cassette, ducted and multi-unit installations usually take 1 to 3 days.
The aircon unit is bought separately or we can also supply the unit - ask for a supply-and-install quote. Fitting out an office or shop? See our commercial service.
When an aircon stops doing its job, the cause isn't always obvious. We test the system properly, explain the fault in plain language and give you a price before we fix anything. Diagnosis from R500.
The most common causes are a dirty filter, dirty coils, low refrigerant from a leak, or a fault with the outdoor fan or compressor. First clean the filter and check the remote is set to cooling. If the room still doesn't cool, a technician needs to test the gas pressures and the outdoor unit.
Water dripping from the indoor unit is nearly always a drainage problem - a blocked drain line, a unit that isn't level, or ice on the coil melting. A blocked drain is usually a quick fix. Switch the unit off to protect your walls and electrics, then give us a call.
| Problem | Likely cause | What you can check first |
|---|---|---|
|
Blowing warm air |
Outdoor fan or compressor not running, or low gas |
Is the outdoor unit running and unblocked? If it’s silent, switch off |
|
Strange noises |
Loose panel or bracket, worn fan motor, electrical or compressor fault |
Loud banging from outside – switch off and call us |
|
Weak airflow |
Dirty filter or coil, failing indoor fan |
Clean the filter |
|
Tripping the power |
Capacitor, wiring, water in the electrics or compressor fault |
Don’t keep resetting the breaker |
|
Won’t switch on |
Control board, sensor or wiring |
Remote batteries, plug, isolator and DB board |
|
Musty smell |
Mould or dirt on the coil and drain tray |
Book a service with a coil clean |
|
Burning smell |
Electrical fault |
Switch off immediately and call us |
|
Ice on the coil or pipes |
Poor airflow or low gas |
Switch off to thaw, then book a check |
The compressor is the heart of the outdoor unit - when it fails, the system stops cooling altogether. Compressor replacement starts from R3,500 and indoor unit replacement from R1,500.
| Repair usually makes sense when | Replacing is worth considering when |
|---|---|
|
The unit is under about 8 years old |
The unit is 10+ years old |
|
The fault is a part like a fan, sensor or capacitor |
The compressor has failed on an older unit |
|
It cooled well until recently |
It has needed several repairs in a short time |
|
It uses R410A or R32 gas |
It uses R22 gas, which is being phased out |
If a repair doesn't make financial sense, we'll tell you - and quote on a replacement instead.
Most repeat breakdowns start with a skipped service. Regular servicing keeps your aircon cooling properly, keeps the electricity bill down and catches small problems early. Minor service from R550, major service from R860.
A minor service cleans the filters and checks that the unit is cooling and draining properly. A major service adds a deep clean of the indoor and outdoor coils, the fan and the drain line, plus gas pressure and electrical checks. If we find a fault, we tell you and quote before doing any extra work.

Looking after several units? We service them on a schedule, keep a simple record for each unit and flag anything that needs attention - ideal for rental properties, office parks, shops and body corporates.
If your aircon is low on gas, it has a leak - aircons are sealed systems and don't "use up" gas. We find the leak, repair it, then recharge the system to the manufacturer's specification. Regassing fromR750; leak repair quoted once it's found.
Regassing means refilling an aircon with refrigerant, the gas that carries heat out of the room. Because an aircon is a sealed system, it only loses gas through a leak. A proper regas finds and repairs the leak first, removes air and moisture, then recharges the system with the correct gas and amount.
These can also be caused by dirty coils or a failing fan, so we always test before adding gas.
Adding gas without fixing the leak means paying again when it runs out - sometimes within weeks - and running low strains the compressor, the most expensive part of the system. So we do it properly:
The gas type is printed on the sticker on your outdoor unit. If your unit uses R22, has a major leak in the coil, or the compressor has been damaged by running low, replacing it is often the better investment - we'll tell you honestly.
| Gas | Found in | What to know |
|---|---|---|
|
R22 |
Older units (roughly pre-2010) |
Being phased out; harder to find and more expensive. Often a sign to consider replacing |
|
R410A |
Most units from the last 10-15 years |
Widely available |
|
R32 |
Many newer inverter units |
More efficient; mildly flammable, so it must be handled correctly |

Simple jobs are quoted from photos; bigger jobs get a site visit first.
At a time that suits you, with your home or premises left clean.
Nothing is signed off until it's cooling and draining properly - and it's backed by our 6-month workmanship warranty.
From our base in Boksburg we cover Edenvale, Kempton Park, Johannesburg, Sandton, Midrand, Pretoria and Krugersdorp, and take on work in Limpopo, Mpumalanga, North West and the Free State.
Yes. Send us the model and a photo of the room and we'll quote on installation only. It's worth checking the size with us before you buy.
Somewhere with free airflow, out of the way of foot traffic, and as close to the indoor unit as practical. Shorter pipe runs cost less and work more efficiently.
For rooms used many hours a day, usually yes. Inverter units adjust their speed instead of switching fully on and off, so they use less electricity and keep the temperature steadier.
Drilling the pipe hole creates some dust. We cover the area, clean up afterwards and take our rubbish with us.
Many faults are fixed on the day. If a part needs ordering, we'll tell you the cost and how long it will take first.
Yes, including multi-unit sites, cassettes and ducted systems.
About 45 minutes to an hour for a minor service and 1 to 2 hours for a major service on a standard wall split.
Yes, and it helps. Rinse the filters every few weeks in summer. It doesn't replace a proper service, which cleans the coils, fan and drain.
No. A healthy system shouldn't need gas. If the pressures are low, there's a leak, which we quote on separately.
It shouldn't. A healthy aircon keeps the same gas for its whole life. If it needs gas, it has a leak that should be repaired.
Usually 1 to 2 hours on a wall split. Finding and repairing the leak can add time, depending on where it is.
No. We work on building air conditioning only, not vehicles.
Yes. All our workmanship carries a 6-month warranty. New units and parts are covered separately by the manufacturer or supplier.
