Aircon installation cost for a supplied and installed 12,000 BTU split runs from about R7,500 to R16,500 in published South African prices (ServiceLink SA's are labelled Q1 2025). Labour alone is published at about R1,500 to R4,000. These are other companies' figures, not ours. Your price depends on pipe length, wall type, electrical work and access.
A fair price needs a look at your site
In published prices, anything from the high R7,000s to about R16,500 for a single 12,000 BTU room. You can see the spread in the table below, and it's wide for a reason.
Two homes can want the same 12,000 BTU unit and get very different bills. One has a short pipe run through plasterboard on the ground floor. The other needs a long run through double face-brick, an outdoor unit on the first floor and a new circuit from the distribution board. That's two very different jobs.
So we won't give you a number from a web page. What we can do is show you what is published and explain what moves it. Then send a request and we'll call you back to go through the job and confirm the price and scope. You'll know both before you agree to anything.
Aircon installation prices side by side, source by source
Every row comes from a South African company or guide, with its date. They differ, and they're not ours. Where a page doesn't say whether VAT is included, we haven't assumed it. Use the table to know what to ask about, then compare quotes with the same scope.

What the table shows.
The same size of unit runs from R7,500 to about R16,500 across these sources. Some of that is the unit and brand. Some is what each company counts as "standard", such as how many metres of pipe are in the base price. Labour-only figures overlap more, at roughly R1,500 to R4,000, but what each company counts as labour differs, and ServiceLink SA's own prose and table give different labour ranges.
The two inverter rows are two separate ranges, not a matched-model comparison. A fair comparison needs like-for-like models and installation scope.
Not every page says what the figure includes or whether VAT is in it. Ask.
And ducted jumps to a different scale altogether. It needs a design, not a quote from a price list.
What sets your aircon installation price
Seven things set your price.
| What changes | Why it moves the price | What to tell us |
|---|---|---|
| Size of unit (BTU/h) | Bigger units cost more, and rooms that need them cost more to install | Room size and which way it faces |
| Inverter or fixed-speed | Inverter units usually cost more to buy. ServiceLink SA publishes installation labour as similar for both types | Whether you'll run it daily |
| Pipe run | Extra copper, insulation and trunking beyond the standard run are charged per metre | Where the outdoor unit could go |
| Wall type | Core-drilling double face-brick or concrete takes longer than plasterboard | Brick, plaster or concrete |
| Electrical work | Changes to the supply or a new circuit can add cost. Ask what electrical work the quote includes | Where your distribution board is |
| Mounting and access | Brackets or a stand for the outdoor unit, and work at height | Ground floor or upper floor |
| What the quote includes | VAT, travel and extras differ from quote to quote | Ask what's in and what's out |
Leon's Air, Flowleads and Kandua all name pipe length, wall type, electrical work and access or height among the things that move a price. Different companies, same list.
Pick the size by the room, not the floor plan
Cooling capacity is measured in BTU per hour (written BTU/h, shortened to BTU in sales listings). A 12,000 BTU/h unit has about 3.5 kW of cooling capacity. You don't need to do the maths. You need to know that more capacity means more cooling, and more cooling isn't always better.
Here is how one published guide pairs unit sizes and rooms (Flowleads, 3 June 2026):
| Unit size | Room example in that guide |
|---|---|
| 9,000 BTU | Small bedroom or office, up to 18 m2 |
| 12,000 BTU | Standard lounge or bedroom, up to 25 m2 |
| 18,000 BTU | Large open-plan room, up to 40 m2 |
Floor area is the starting point, not the answer. One installer's rule of thumb (Aircon Master, 20 Sep 2026) is roughly 500 to 600 BTU/h per square metre for a standard 2.4 metre ceiling, which puts a 20 m2 lounge at 10,000 to 12,000 BTU. Under that rule a 25 m2 room would want more than 12,000, so the two sources don't line up exactly. What closes the gap is the room: afternoon sun on a west or north-facing wall, big windows, a high ceiling, a kitchen next door, four people working in it.
Get it too small and the unit may run flat out and struggle. An oversized unit can cycle too frequently, particularly if its minimum output is too high for the room. Van Biljoens, a South African supplier (13 Jun 2026), says an oversized unit will short-cycle and waste energy, and that repeated starts add wear. Size it using the room's cooling load, not floor area alone.
How long does AC installation take?
The cited installers give different estimates: roughly two to three hours for some back-to-back jobs and three to five hours for some standard single splits. Access, electrical work and pipe routes can extend the job. The aircon installation page has the detail and what stretches a job.
Questions to ask before you compare two quotes
A cheaper quote may cover less. Ask each company the same five things:
- Does the total carry VAT?
- How many metres of pipe are in the price, and what is each extra metre?
- Who supplies the brackets, trunking and drain, and are they in the total?
- Who does the electrical work, and who signs off the Certificate of Compliance for a new circuit?
- Who does the refrigerant work, and are they an SAQCC Gas registered practitioner?
The last two aren't optional extras. Two requirements apply to the work itself.
Work on the refrigerant circuit needs an SAQCC Gas registered practitioner.
A new electrical circuit needs a Certificate of Compliance from a registered electrician.
A price that leaves them out is a price for part of the job.
Choosing between unit types as well? The inverter aircon page explains how the two differ and what to check before you decide.

Questions people ask
How much to install air conditioning in South Africa?
Published prices for a supplied and installed 12,000 BTU split run from about R7,500 to R16,500: ServiceLink SA R7,500 to R13,500 (16 Feb 2026, prices labelled Q1 2025), Blue Line Air from R7,999 (2 Jul 2026), Flowleads R9,500 to R14,000 (3 Jun 2026) and Kandua up to about R16,500 (summary labelled 2025). Labour alone is published at about R1,500 to R4,000. Your price depends on pipe length, wall type, electrical work and access, so a fair price needs a look at your site.
How long does AC installation take?
The cited installers give different estimates: roughly two to three hours for some back-to-back jobs and three to five hours for some standard single splits (ServiceLink SA, 16 Feb 2026; Aircon Master, 20 Sep 2026). Access, electrical work and pipe routes can extend the job. The aircon installation page has the detail.
Does the price include VAT?
Ask. Not every price page says. Leon's Air lists VAT among the things that change a quote, and a price that excludes it isn't comparable with one that includes it.
Does an inverter unit cost more to install?
Not by much, going by what's published. ServiceLink SA says installation labour is similar for both types. The bigger difference is the price of the unit. ServiceLink lists a 12,000 BTU inverter unit at R8,000 to R13,000 and a non-inverter at R6,000 to R9,000 (16 Feb 2026, prices labelled Q1 2025). Those are two ranges, not a matched-model comparison. See the inverter aircon page for more.
What size aircon do I need for a 20 m2 room?
One installer's rule of thumb puts a 20 m2 lounge at 10,000 to 12,000 BTU before adjustments (Aircon Master, 20 Sep 2026). Another guide pairs 12,000 BTU with rooms up to 25 m2 (Flowleads, 3 Jun 2026). Sun, glass and ceiling height can move that either way, so tell us what the room faces.
Can you give me a fixed price over the phone?
Not before the job is understood. Send a request and we'll call you back to go through the job and confirm the price and scope. You'll know both before you agree to anything.
Does the price cover the paperwork?
It should say. Work on the refrigerant circuit needs an SAQCC Gas registered practitioner.
A new electrical circuit needs a Certificate of Compliance from a registered electrician.
Ask whether both are covered in the quote.
