Cassette aircon installation in Cape Town fits the unit into the ceiling, with only a flat grille visible below. Air is thrown out across the ceiling in four directions, which distributes it more evenly than a wall head can.
It is the standard choice for offices, shops and restaurants, and occasionally for homes with a suspended ceiling and open-plan space.

- Even distribution from a central position, rather than one wall blowing across a room.
- Nothing on the walls, which matters for shelving, display and shopfitting.
- Discreet appearance in a suspended ceiling grid.
- Larger capacities available than typical wall units.
- Multiple cassettes zone a floorplate cleanly.
What the Ceiling Has to Provide
| Requirement | Typical |
|---|---|
| Void depth above the ceiling | Around 300 – 400 mm for most cassettes |
| Grid opening | Commonly 600 × 600 mm or 840 × 840 mm depending on the model |
| Support | Threaded rod to the slab or structure, not the ceiling grid itself |
| Drainage | Condensate pump, since gravity fall is rarely available in a void |
| Pipe and cable routes | Run in the void to the outdoor unit position |
| Service access | Filter and drain pan reachable through the grille |
Void depth is the first thing to check and the most common reason a cassette gets ruled out. Where there is not enough room above the ceiling, an under-ceiling suspended unit does much the same job while hanging below the ceiling line.
Drainage and Condensate Pumps
A cassette sits in a void with no natural fall, so almost all installations use an integral or external condensate pump lifting the water to a drain point. It is a wear item and it is the most common cassette failure — and when it fails, water appears through a ceiling tile rather than dripping down a wall. Ask for the pump to be included in the maintenance schedule.
Where Cassettes Fit
- Offices. One or more per open-plan area, zoned to match how the floor is used.
- Shops. Central position clears the walls for shelving and display.
- Restaurants. Dining areas, kept away from the kitchen's grease-laden air where possible.
- Boardrooms and training rooms. High occupancy loads, distributed rather than blasted from one wall.
- Homes. Only where a bulkhead or suspended ceiling provides the void.

Indicative Cape Town ranges, not a quotation. Cassettes cost more than wall units of the same capacity, and the installation is a bigger job. Ceiling work, void access and after-hours requirements move the number most.

Compare Cassette QuotesFrequently Asked Questions
How much ceiling space does a cassette aircon need?
Most four-way cassettes need roughly 300 to 400 mm of clear void above the ceiling, plus room to run pipework and the drain. Where the void is shallower, an under-ceiling suspended unit is the usual substitute.
Can a cassette aircon be installed in a house?
Yes, where there is a suspended ceiling or a bulkhead deep enough to take it. In a standard Cape Town home with a flat ceiling and a roof space above, installation is possible but usually more disruptive and expensive than a wall unit.
Why does a cassette need a condensate pump?
Because it sits inside a ceiling void with no natural fall to a drain. The pump lifts the condensate to a point where it can run away by gravity. It is a wear item, so it belongs in the service schedule.
How much does a cassette aircon cost installed in Cape Town?
A 12000 BTU cassette supplied and installed commonly runs R22,000 to R38,000, with larger units correspondingly higher. Ceiling work and long pipe runs in a commercial void push it up.
Are cassettes noisier than wall units?
Not inherently, and often less obtrusive because the air is distributed across the ceiling rather than blown down one side of the room. What people do notice is the condensate pump cycling, which is normal.
