Commercial air conditioning in Cape Town covers everything from a two-cassette shop to a VRF system across an office building. What separates it from domestic work is not size alone — it is that the system has to keep running during trading hours, and that a failure has a cost attached.

What Drives Commercial Heat Load
- Occupancy. Roughly 100 W of sensible heat per seated person, more with activity.
- Lighting, especially display and track lighting in retail.
- Equipment. Computers, tills, kitchen appliances, refrigeration cabinets and server cupboards.
- Glazing and orientation, which in Cape Town means west-facing facades above all.
- Doors. An open shopfront loses conditioned air continuously and has to be designed for.
- Fresh air requirements, which are a load in their own right.
Commercial systems are sized on a calculated load, not on floor area. If a quote for a commercial space arrives with no load calculation behind it, ask what it was based on before comparing it against anything else.
Installation on a Trading Premises
Most commercial installation happens after hours or over weekends, which carries a premium and needs to be agreed upfront. Landlord approval, building management access, hot work permits, lift bookings and roof access are all normal parts of the scope, and they belong in the quote rather than appearing later.

Indicative Cape Town ranges, not a quotation. On commercial work the scope differences between quotes are usually larger than the price differences. Compare the unit schedule, the electrical scope, the access arrangements and the commissioning and handover documents.

How much does commercial air conditioning cost in Cape Town?
A small shop with two cassettes commonly runs R60,000 to R105,000 installed. A small office with four to six units typically falls between R120,000 and R280,000. VRF is benchmarked per kW, usually R11,000 to R22,000.
Do I need landlord approval to install aircon in a rented premises?
Almost always, particularly for anything penetrating the building fabric or mounting plant on a roof or facade. Get it in writing before appointing, and check what condition the premises must be returned in at lease end.
Can commercial aircon be installed outside trading hours?
Yes, and it is the norm. Expect a premium of roughly 15 to 35 percent, and confirm building access, permits and lift bookings are included in the scope.
How often should commercial air conditioning be serviced?
Quarterly is the usual baseline for offices and retail. Restaurants and kitchen-adjacent units generally need more frequent attention because grease loads the coils.
Who is responsible for aircon in a leased building?
It depends entirely on the lease. Some place maintenance on the tenant, others keep plant with the landlord and recover costs. Check the lease before assuming either, and do not rely on how the previous tenant handled it.
