LocationsYour state for the rules, your city for the climate.

What each page covers

State pages cover the licence rules, where to check a licence, and any rebate or rental rules that apply there. They matter most when you've got a quote in front of you.

City pages start from the local climate, using Bureau of Meteorology averages from a named weather station, then cover the jobs that come up most there: heating in a cold city, cooling and humidity in a tropical one, salt air on the coast.

Heating, cooling, or both?

The zoned energy rating label you'll see on a new split system rates it for three climate zones: hot, average and cold. The example label in the ACT Government's guide groups Brisbane and Darwin as hot, Adelaide, Perth and Sydney as average, and Canberra, Hobart and Melbourne as cold.

The gap between them is wide. Darwin Airport's July mean minimum is 19.3 degrees, while Canberra Airport's is 0.3 degrees, and the ACT Government says heating makes up about 60% of the average Canberra household's energy use. If your city is on the cold list, read its page for heating first.

Can't see your town?

The lists below show the cities we've written about so far, not the edge of where an installer might help. Your postcode on the quote form decides which local installers see your job first. Areas we cover now: areas covered.
