Ceiling aircon installation in Cape Town covers three different unit types that all end up at ceiling level. Which one suits depends almost entirely on what is above your ceiling.
Describe the ceiling — suspended, concrete slab, or a flat ceiling with roof space — and get quotes.

| Type | Where it sits | Needs | Best for |
|---|---|---|---|
| Four-way cassette | Recessed into the ceiling, grille flush | 300 – 400 mm void | Offices, shops, suspended ceilings |
| Under-ceiling (suspended) | Mounted below the ceiling, visible | No void required | Concrete slabs, warehouses, halls, long rooms |
| Concealed ducted head | Hidden in the void, feeds grilles | Deep void plus duct routes | Multiple rooms from one unit |
Under-Ceiling Units
Where there is no void — a concrete slab, an exposed structure, a converted space — an under-ceiling unit hangs below the ceiling and throws air horizontally along the room. It is visible, which is the trade-off, but it handles long narrow spaces well and it is far easier to install and to service than anything recessed.
Common in warehouses, workshops, church halls, gyms, showrooms and older commercial buildings in the Cape Town CBD where the slab is exposed.
Choosing Between Them
- Suspended grid ceiling with depth above it. Cassette, almost always.
- Concrete slab, nothing above. Under-ceiling unit, or a wall-mounted split.
- Several rooms off one space with deep void. Concealed ducted head.
- Flat ceiling with roof space above in a house. Possible for all three, but a wall split is usually cheaper and less disruptive.
- Appearance critical. Cassette or ducted, since both hide the equipment.
Every ceiling-mounted type needs a plan for condensate. There is no gravity fall in a void, so a pump is normal, and its discharge line has to reach somewhere sensible. Ask where the water is going before the unit is ordered.

Indicative Cape Town ranges, not a quotation. The ceiling itself sets the price more than the cooling capacity does. Get the void measured before comparing quotes, because a cassette quoted against a void that does not exist is not a quote you can use.

Compare Ceiling Aircon QuotesFrequently Asked Questions
What is the difference between a cassette and an under-ceiling aircon?
A cassette is recessed into the ceiling so only the grille shows, and it needs a void above. An under-ceiling unit hangs below the ceiling and needs no void, which makes it the option where there is a concrete slab overhead.
Can I install a ceiling aircon in a normal house?
Usually yes, if there is roof space or a bulkhead, but it is more disruptive and more expensive than a wall-mounted split. Most Cape Town homes end up with wall units for that reason, and cassettes only where a suspended ceiling already exists.
How much void do I need above the ceiling?
Roughly 300 to 400 mm for a typical four-way cassette, plus space to route the pipework and the drain. Concealed ducted heads need considerably more because the ducting has to run as well.
Do ceiling aircons need a drain pump?
Almost always, because there is no gravity fall inside a ceiling void. The pump lifts condensate to a point where it can drain away, and it should be inspected as part of every service.
Which is cheaper to install, cassette or under-ceiling?
Under-ceiling units are usually cheaper to install because there is no ceiling work and access is straightforward. Cassettes cost more but disappear into the ceiling, which is generally why they are chosen.
