Air conditioning Cost Calculator

Air conditioners are priced per unit - by BTU cooling capacity and unit type (split, inverter, multi-split), not by floor area. Use this tool to estimate a realistic per-unit budget from published South African pricing before you compare quotes from independent local air conditioning contractors.

Unit type (split vs inverter)Non-inverter split systems are cheaper to buy and install initially, while inverter models cost more up front but run more efficiently. In the listed units, a 9 000 BTU non-inverter Samsung retails around R6 550 versus R9 520 for a 12 000 BTU LG Dual Cool inverter.BTU cooling capacityRoom size, ceiling height, sun exposure and occupancy determine the BTU needed - roughly 10 000-12 000 BTU for small living rooms and 18 000-24 000 BTU for larger open-plan areas. A 12 000 BTU unit often needs heavier piping, secure mounting and dedicated electrical work.Brand and warrantyBrand choice affects price, warranty terms and parts availability. Listed brands include Samsung, LG, Alliance, Jet-Air, York and Midea, with popular reliable names in SA also including Daikin and Mitsubishi Heavy Industries.Installation access and complexityPiping complexity, wall type, working at height, roof or balcony access, long refrigerant line sets and electrical panel upgrades all add time and materials. Restricted access or civil work such as holes in brickwork and replastering increases labour charges.VAT and additional materialsQuoted figures should include 15% VAT as required locally, plus brackets, copper piping, condensate drains and commissioning. Removal and disposal of an old unit may be included or charged extra depending on the contractor.

These are estimated price ranges based on general South African market data. Actual prices are set independently by each provider and may differ. Always request a written, itemised quote before any work begins.

How to use this estimate

Start from the published per-unit price band, then toggle the cost factors that match your job - unit type and BTU capacity, brand, and how difficult the installation access is. The figure shown is a rough budgeting guide to help you sense-check the quotes you receive. Independent contractors set their own prices, and the final cost depends on the exact unit chosen, pipe run, electrical work and site access. It is worth deciding between an inverter and non-inverter unit first, since that choice moves both the upfront price and the running cost.

What drives the price

· BTU cooling capacity for the room size
· Unit type - non-inverter, inverter, multi-split or cassette
· Brand, warranty and installation complexity

What it usually excludes

· Long refrigerant pipe runs and extra copper
· Electrical panel upgrades or a dedicated circuit
· Removal of an old unit and after-hours work

These extras are often quoted as separate line items, so always confirm the full scope in writing with your chosen contractor before work begins. For typical ranges by unit type, see the air conditioning price guide.
