Office aircon installation in Cape Town
We fit wall-mounted splits in small offices, consulting rooms and shops. The units are the same as the ones in a house. What changes is who has to agree to the work, who carries the paperwork, and which rules apply to the building.
If you rent, start with the landlord. If the building is a sectional-title scheme, the trustees come into it too. The detail is below.

Certificates, and who has to get them
Under the Pressure Equipment Regulations, the Department of Employment and Labour's guidance says the certificate of conformity for installing or servicing a refrigeration system must come from an SAQCC Gas registered practitioner, and the standard it names, SANS 10147, covers refrigerating systems including plants associated with air-conditioning systems. The installer who does the work must be SAQCC Gas registered. Ask to see the card, and you can check it on SAQCC Gas's practitioner search.
On the electrical side, the Electrical Installation Regulations place the duty on the user or lessor. After an addition or alteration, a dedicated aircon circuit for example, they must obtain a certificate of compliance for at least that work, and only a registered electrical contractor may do electrical installation work as a contractor.
Older premises need a closer look. Where the installation dates from before 23 October 1992 and hasn't changed owner since 1 March 1994, any addition or alteration means a certificate for the whole installation. In a rented unit, settle with the landlord who arranges and pays for that before work starts.
Noise, plans and the building itself
The Western Cape Noise Control Regulations of 2013 limit air-conditioning equipment to 50 dBA on the property boundary, or 5 dBA above the background noise. That clause is written for residential areas, and the regulations don't define the term. A shopfront on a busy road and a converted house on a quiet street are different cases, so when your premises sit among homes we place the outdoor unit as if the limit applies.
The City's guide on artificial ventilation requirements, dated 14 October 2019, also lists a maximum of 50 dBA on the boundary for residential applications. That guide is for ventilation and air-conditioning plans submitted to Council. It doesn't say a single split unit needs plans, and we haven't found a City statement either way.
If your office is a section in a sectional-title scheme, the default conduct rules need the trustees' written consent before anyone drives screws into common property (rule 4) or changes the external appearance of a section (rule 5). An outdoor unit likely needs that consent. Schemes can adopt their own rules, so check your scheme's rules.
Older buildings bring heritage rules in. The City says a Heritage Western Cape permit is required for any alteration to a building older than 60 years, and properties in Heritage Protection Overlay zones must follow Chapter 20 of the Municipal Planning By-law. Whether an aircon counts as an alteration isn't stated, so an older building may need a permit.
Sizing a bigger room
Open-plan offices run larger than most bedrooms, and that's where the brand charts thin out. LG South Africa lists 24 000 BTU for 40 to 60 m² and 36 000 BTU for 60 to 80 m². Midea's table gives 30 000 BTU for 55 to 60 m² and says larger areas need an installer to advise. Samsung Air's rule of thumb is about 600 BTU per m². LG names room size, insulation, sunlight and ceiling height as the factors that change the answer, and no chart can see those in your building, so we measure on site. The side-by-side sizing table on our home installation page covers smaller rooms.
Taking over premises with an old unit? Since 1 January 2015, R22 and other HCFC refrigerants may not be used in installing a new system, and our repairs and regas page explains what that means for keeping an existing R22 unit going.
Buying units in 2026 or 2027
On 28 August 2026 the government gazetted an amended VC 9008, the compulsory energy-efficiency and labelling specification, covering air conditioners up to 16 kW (55 000 btu/h) of cooling. Phase 1 takes effect 12 months after publication and Phase 2 after 24 months, so from about August 2027 and August 2028. It binds manufacturers and importers, not installers or units already installed, and it isn't in force yet.
Need more than one unit? One Western Cape price list we read prices by the number of units installed, and it sits with the others in our aircon installation price guide. We quote offices across the city, from Bellville to Somerset West.
