Air conditioning installation in Canberra

How much does air conditioning cost in Canberra?

These are estimated installed prices for a standard single-storey Canberra job in 2026, with an ARCtick licensed installer, a short back-to-back pipe run and a basic electrical connection. Few Canberra installers publish price lists, so the bands lean on installer guides, ACT retailer install fees and nearby Sydney pricing. Units sized for heating are bigger than units sized for cooling the same room, which pushes a Canberra job up a size.

The split system cost guide and the ducted cost guide explain what moves a quote within these bands. To see where your house sits, compare quotes from up to three licensed Canberra installers.

Buy a reverse cycle for Canberra winters, not summers

At Canberra Airport the Bureau of Meteorology records an average July minimum of 0.1 degrees and an average July maximum of 12.8. January averages 30.0 degrees, so you need cooling too, but heating is the job that decides the size and the model. The ACT Government puts heating and cooling at about 60 percent of an average Canberra household's energy use.

Canberra is the reference city for the cold zone on the Zoned Energy Rating Label that every new air conditioner carries. Read the heating figures for the cold zone, not the headline star rating. The ACT Government's buyer's guide suggests looking for a unit's low-temperature heating rating, because efficiency changes with the outdoor temperature.

• Size the living area for a frosty morning. Our sizing guide and calculator cover the maths.
• For ducted, ask for insulated ductwork of at least R1.5. The ACT guide flags heat loss from poorly insulated ducts in the roof.
• Mount the outdoor unit clear of the ground and where defrost water can drain away. Ice on a shaded path is a Canberra winter hazard.

Replacing gas and slab heaters in Canberra

Belconnen, Woden, Weston Creek and Tuggeranong are full of 1970s and 1980s brick homes with gas ducted heating or old electric slab heaters. Replacing either with reverse cycle is the most common Canberra job we see. The ACT Government states that reverse cycle costs less to run than gas heating or other electric heating.

Gungahlin suburbs like Ngunnawal, and newer Molonglo Valley suburbs like Wright, have roof spaces that suit ducted. Inner North homes in Braddon and older Narrabundah houses tend to need splits or a multi-head. Apartments there are strata, so get owners corporation approval before any work on common walls.

ACT air conditioning rebates and loans in 2026

The ACT has no VEU-style discount for every household. It has two targeted programs. The Sustainable Household Scheme offers eligible homeowners low-interest loans from $2,000 to $20,000 at 3 percent, repaid over up to 10 years, and electric heating and cooling systems are an eligible product. The Home Energy Support Program gives homeowners who hold a Pensioner Concession Card, Health Care Card or DVA Gold Card a rebate of 50 percent of supply and installation for reverse cycle heating and cooling, up to $2,500.

Both have conditions, including a workshop and approved products. If you live over the border in Queanbeyan, Jerrabomberra or Googong, you are in NSW, and the NSW Energy Savings Scheme discount may apply instead. See our ACT rebate page and NSW rebate page. If you plan to use a loan or rebate, tell the installers when you get up to three local quotes, so the quotes use an approved product.
