Car air conditioning and heating: what it costs to fit

Updated 4 November 2026

A car air conditioning or heating unit costs about A$85 to A$385 for an evaporator-only kit, A$430 to A$1,480 for a 12V under-dash heat and cool unit, and A$1,790 to A$4,810 for a rooftop unit, according to sellers' websites, November 2026. The quickest way to current prices for your car is a request on BlaBlaPrice, with the make, model and year.

Local rules and warranty

Under the Australian Consumer Law, parts and services sold in Australia carry guarantees that cannot be excluded, so a major failure entitles you to a repair, replacement, refund or cancellation. ACCC guidance quoted in a search snippet says that using quality parts should not void the manufacturer's warranty. Statutory warranty on used cars can leave out air conditioning, and forum discussions note that heater hoses are often excluded too, so ask the seller to write down what the warranty covers before you pay.

Season and the heat

November is late spring here. Summer runs from December to February, the months when cooling matters most, and winter from June to August, when heating matters. One Australian workshop advises a service before summer, but there is no single interval that suits every vehicle, so follow the car's own schedule and ask the workshop what it has checked.

How parts are bought here

Kits are sold for either 12V or 24V systems, so check the car's or truck's voltage before ordering. Ask whether the price includes the evaporator and the hoses, and how long the fitting takes. Ask whether delivery to your city is included, because sellers in Sydney, Melbourne, Brisbane, Perth and Adelaide may quote different delivery costs. Prices are in Australian dollars, so compare the total cost of the kit and fitting, not the unit price alone.

What to put in your request

Give the part you need, the car model and year, the engine, the climate-system type, and whether you want an original or a compatible part. Add the condition you accept, the city where it will be fitted and your budget. A photo of the old unit or its label helps a seller match the part.
