Top Air Conditioning Companies In Canberra For 2027

Last updated: November 14, 2026

The best air conditioning companies in Canberra for 2027 are ACG Air Conditioning Guys Canberra, Delta Air Conditioning & Heating, AirConditioning Canberra, Climate Plus, Landmark Air, ProActive Air Conditioning & Heating, Level Electrical + Air Fyshwick, SolarHub, Shaw Electrix and Blueline Plumbing & Gas. This list is part of our Canberra business services hub.

In Canberra, heating matters as much as cooling. Winter nights regularly drop below zero, so most homes rely on ducted gas, reverse cycle air conditioning or a mix of both. Summers are hot and dry, which is why evaporative cooling is still common in older suburbs.

The big trend is electrification. Many households are replacing ducted gas heating with efficient reverse cycle systems, and some upgrades can be financed through the ACT Government’s Sustainable Household Scheme.

This list of top air conditioning companies in Canberra covers specialist HVAC firms and multi-trade businesses. For related work, see our lists of electricians in Canberra and solar installers in Canberra.

How To Choose An Air Conditioning Company In Canberra

Is Reverse Cycle Better Than Ducted Gas In Canberra?

Modern reverse cycle systems are usually cheaper to run than gas and can be powered by rooftop solar. Ducted gas still delivers strong heat, but gas prices and the ACT’s electrification push are leading many households to switch.

What Size System Do I Need?

Sizing depends on floor area, insulation, ceiling height and window orientation. A good installer will do a heat load calculation rather than guessing from room size alone.

How Often Should Heating And Cooling Be Serviced?

Most systems benefit from a service every one to two years. Gas heaters need regular safety checks, so book a licensed gasfitter before winter.

Can I Get Help Paying For An Upgrade?

The ACT Government’s Sustainable Household Scheme offers low-interest loans for eligible electric heating and cooling. Some energy retailers also run gas-to-electric incentives, so ask your installer what applies.

Conclusion

For large installs and ongoing servicing, ACG Air Conditioning Guys and Delta Air Conditioning & Heating are the most established names, while AirConditioning Canberra stands out for repairs and ducted heating.

Also worth a look: Landmark Air and ProActive Air for ducted heating and evaporative cooling, and SolarHub if you are switching from gas to electric.

Whoever you choose, ask for a heat load calculation, a written quote and details of the warranty on both product and installation.
