Who may do the work. The construction licences issued through Access Canberra include builders, electricians, plumbers, drainers and gasfitters, gas appliance workers, surveyors and assessors, and none of them is for air conditioning or refrigeration. The trade reaches the licensing system through its electrical and gas work. The electrician licence includes a restricted class for refrigeration and air-conditioning, limited to incidental wiring for disconnection and reconnection, and the Electrical Inspections team's fact sheet on split systems states that a restricted licence holder may disconnect and reconnect low-voltage wiring but not install it; the same sheet sets out the AS/NZS 3000 isolator rules for outdoor and indoor units. The ACT Government's buyers guide puts it simply for homeowners: installing a reverse cycle system needs an ACT licensed electrician, and replacing a gas system also needs an ACT licensed plumber. Refrigerant handling is licensed nationally by the Australian Refrigeration Council. The ACT's advertising rule for licensed trades (the name on your licence, its number and, for a company, its ACN) is set out on our Canberra tradies page.
A heating market first. The ACT Government's guide to reverse cycle systems says heating makes up about 60% of the average Canberra household's energy use. The Bureau of Meteorology's Canberra Airport station, open since 2008, averages 0.1°C overnight and 12.9°C by day in July, and it recorded 44.0°C on 4 January 2020; the older airport station it replaced bottomed out at −10.0°C on 11 July 1971. The national Zoned Energy Rating Label calculates its cold-zone figures from Canberra's climate file, and its 2°C heating capacity is there to show how a unit copes with frosting conditions, since outdoor coils start to frost once the air drops below about 5.5°C. The ACT guide suggests looking for an H2 rating for Canberra winters, and the Home Energy Support rebates for eligible homeowners set firmer terms: the system must heat and cool, be listed on the GEMS register, be able to operate in the cold zone and meet minimum annual efficiency figures. Few buyers know what any of that means, so a site that explains it does work the quote would otherwise have to do.
The move off gas. New gas network connections have been blocked in the ACT's residential, commercial and community facility zones since 8 December 2023, and the ACT Government's 2026 discussion paper on future gas appliance rules shows how far heating has already moved. Among ACT households with a gas connection, 69% use electric space heating and 43% gas (dual-fuel homes count in both), the highest electric share in Australia. In a survey of 1,885 households cited in the paper, 59% of residential respondents said they intend to go electric when their gas appliance breaks, and another 28% will weigh up the costs at that point. Evoenergy expects about 40,000 customers, roughly a third, to stop using gas between 2026 and 2031, and some sections of the network may begin to shut down from the mid-2030s. Consultation ran from 5 August to 16 September 2026, and the example the paper gives of how rules could help installers plan is stopping new gas space heating installations in two years. For the cost, the Sustainable Household Scheme offers 3% loans through Brighte (our Canberra electricians page covers how suppliers take part), and under the Energy Efficiency Improvement Scheme, ActewAGL and Origin Energy are the retailers delivering upgrades; ActewAGL's current offer covers replacing ducted gas heating with ducted reverse cycle through its approved installers.
Where the outdoor unit goes. Under the Planning (Exempt Development) Regulation 2023, an external air conditioner is exempt from development approval, provided it also meets the general exemption criteria, if no part of it is within 1.5 m of a side or rear boundary, a roof-mounted unit rises no more than 1.5 m above the roof and stays inside any solar building envelope, and a ground-mounted unit sits behind the building line. Places on the ACT Heritage Register lose that exemption unless the Heritage Council advises in writing that the work won't diminish the place's heritage significance or follows its heritage guidelines. The conservation policy the Council uses when advising says units shouldn't be visible from the street or other public places, should sit at ground level with screening (evaporative units aside) and shouldn't go on a roof that can be seen from the street. Registered places include the housing precincts in Reid, Braddon, Barton and Forrest. Noise is regulated separately: Access Canberra's residential standard is 45 dB(A) by day and 35 dB(A) overnight, and 5 dB(A) lower in multi-unit developments. In unit complexes, the Unit Titles (Management) Act lets an executive committee approve a minor use of common property, and the Act's own example is an air conditioner that extends over it.
Districts, the border and us. Canberra has no local councils, so customers search by suburb and district; we list the districts you cover, from Gungahlin and Belconnen in the north to Woden and Tuggeranong in the south, with the suburbs under each. Queanbeyan, Googong and Jerrabomberra are in NSW, where air conditioning work needs a NSW licence, and our Sydney air conditioning page explains those rules. We're an Adelaide team on Hutt St and work with Canberra businesses by phone and email. We haven't built a site for a heating and cooling business or an ACT client yet; our current clients are in SA, NSW, VIC and QLD.
