A planning range for one straightforward back-to-back split unit, usually with a limited standard pipe run. The unit itself is excluded.
Honest planning ranges
What does aircon installation cost?
Start with a realistic range, then understand which parts of your property and system move the final number.
The short answer
For planning, a straightforward back-to-back split-unit installation often costs about R2,500–R6,500 excluding the aircon. A typical residential unit plus standard installation may total roughly R8,000–R25,000. These are guidance ranges, not guaranteed prices: capacity, pipe length, access, wall construction and electrical work determine the site-specific quote.
Budget snapshot
Three useful levels of cost
Prices should always be confirmed in writing after the installer understands the site. VAT inclusion, travel and optional extras must be clear on the quote.
A broad residential planning range. Unit capacity, efficiency, brand, warranty and included materials account for much of the spread.
Several zones, ceiling work, grilles, long pipe routes and complex controls need a designed scope rather than a responsible one-line estimate.
Why quotes differ
The six biggest price movers
A cheap installation can become expensive when the original scope hides the parts the room actually needs.
- Capacity and efficiencyHigher BTU output and stronger efficiency ratings usually increase equipment cost.
- System typeA single wall split is simpler than multi-split, cassette or ducted equipment.
- Pipe-run lengthExtra copper, insulation, control cable and trunking are usually priced per metre.
- Wall and accessConcrete, upper floors, scaffolding and awkward outdoor positions add labour or equipment.
- DrainageA natural fall is simplest; a condensate pump or long concealed route costs more.
- Electrical workA dedicated circuit, isolator or distribution-board change must be scoped safely.
Ask these questions before comparing totals
- Is VAT included?
- How many metres of copper pipe are included?
- Are wall brackets, trunking and drainage included?
- Is electrical work included or separately quoted?
- What happens if the wall route changes on the day?
- Will the installer issue the required compliance documents?
A fair comparison
Compare scope, not just the last line
Two quotes can look like they describe the same job while one excludes electrical work, extra pipe, brackets or compliance paperwork. Ask for the model number, included materials, route, labour, warranty responsibilities and exclusions in plain language.
It is reasonable for an installer to qualify a price before seeing the site. It is less reasonable to promise a fixed price and reveal essential extras only after work begins.
What to budget beyond installation
Ownership costs still matter
An efficient inverter unit can reduce electricity use compared with an older fixed-speed design, but running cost depends on set temperature, insulation and how long the system operates. Filters need routine cleaning, and professional servicing should reflect use, dust, coastal exposure and warranty terms.
