Split unit aircon installation in Cape Town is the default job: one indoor head on a wall inside, one condenser outside, joined by insulated copper, a drain and a cable. It is what most homes, small offices and shops get, and it is the cheapest air conditioning there is to install.
"Split" refers to the layout, not the technology. Most split units sold now are inverters, but fixed-speed splits still exist at the budget end.

- The noisy parts — compressor and condenser fan — are outside.
- Installation needs one core hole rather than ceiling work or ducting.
- It retrofits into an existing building with minimal disruption.
- Each unit is independent, so one failure does not take out the whole property.
- Parts and technicians are available everywhere in the Cape Town metro.
The trade-off is visible hardware. An indoor head on the wall and a condenser outside, one pair per room. Once you get past about four rooms, ducted or multi split systems start to look tidier.
Where the Units Go
| Element | What it needs |
|---|---|
| Indoor head | High on a wall, clear of obstructions, not blowing directly at a bed or desk |
| Pipe route | As short as practical; every extra metre adds copper and labour |
| Drain | Continuous fall to a discharge point, or a condensate pump |
| Outdoor condenser | Free airflow, shade if possible, away from bedroom windows and boundaries |
| Electrical | Dedicated circuit and an accessible isolator near the unit |
A condenser in full afternoon sun against a west wall works harder for the same cooling. Shade helps, but never at the cost of airflow — boxing one into a tight enclosure for appearance is worse than leaving it in the sun.
Back-to-Back Installation
The cheapest arrangement puts the condenser directly behind the indoor head, through one hole, with under a metre of pipe. Most quotes assume roughly this, with an allowance of about 3 m of pipework included. Anything longer is charged per metre, and it is the most frequent cause of a quote coming in above expectations.

Indicative Cape Town ranges, not a quotation. If you are fitting more than one unit, get them quoted together. The saving on a second unit installed during the same visit is usually significant.

Compare Installation PricesFrequently Asked Questions
What is a split unit aircon?
An air conditioner in two parts: an indoor head mounted on the wall, and an outdoor condenser containing the compressor, connected by insulated copper pipes, a drain line and a cable. The name describes the layout, not the technology.
How much does a split unit installation cost in Cape Town?
A 12000 BTU inverter split supplied and installed back-to-back commonly runs R11,000 to R17,500. Installation only, where you supply the unit, is typically R3,500 to R7,500.
How far apart can the indoor and outdoor units be?
Most domestic splits allow 15 to 25 m of pipe run, depending on the model, with limits on the vertical difference too. Long runs cost more in copper and labour and slightly reduce performance, so shorter is better where there is a choice.
Is a split unit better than a portable aircon?
For anything beyond occasional use, considerably. A portable rejects its heat through a hose out of a window, which leaves the room drawing warm air back in, and it puts the compressor noise in the room with you.
Can one outdoor unit run two rooms?
Only on a multi split system, which is designed for it. A standard split condenser is matched to one indoor head and cannot be shared.
