Ducted Heating Cost in Canberra (2026)
In Canberra ducted heating cost is the biggest energy bill of the year, with gas ducted and reverse-cycle both run hard against the frost.

Where the money goes
Estimated breakdown for your configuration
Zoning lets you heat only the rooms in use, it adds upfront cost but cuts running cost and is worth it in larger homes.
Ways to save
- If the ducting is in good condition, replacing only the unit is much cheaper than a full new system.
- Zoning pays for itself over time in a larger home by not heating empty rooms.
How we estimate this
Ducted heating in Australia typically costs $3,500 to $18,000 in 2026 depending on home size and system. Replacing a unit where ducts exist is cheapest; a new ducted reverse-cycle system with zoning across a large home reaches the top.

What a ducted heating costs in Canberra
Ducted heating cost in Canberra is the biggest energy bill of the year, because the cold, frosty winters and big temperature range have a ducted system running hard for months against sub-zero nights. The fuel decides the shape of the bill: ducted gas heating, long popular in Canberra's cold climate, is billed by the gas burned, while a reverse-cycle ducted system is electric and billed by the power drawn, and the gap between them has narrowed as gas prices rise and reverse-cycle efficiency improves.
Canberra has traditionally leaned on ducted gas for its reliable heat on the coldest nights, but a modern reverse-cycle system is now a strong option, with the caveat that a heat pump's efficiency falls on the very coldest nights, so the low-temperature rating matters in a city this cold. Many ex-government homes are poorly insulated and leak heat, lifting the hours and the bill regardless of fuel, so insulation and draught-proofing pay back strongly here. The high local electricity and gas costs make zoning to heat only the rooms in use the biggest single saving through the long heating season.
Running the heating needs no licence, but the install is licensed by fuel: a ducted gas system must be fitted by a licensed gas fitter, and a reverse-cycle system needs a licensed refrigeration or ARC-certified technician and a licensed electrician, under Access Canberra for the electrical side. For a Canberra home, the clearest way to think about ducted heating cost is the fuel and its cold-weather efficiency times the many months the frost demands, the dominant energy bill of the year.

Frequently asked questions
Is ducted heating the biggest bill in Canberra?
Yes. The cold, frosty winters and big temperature range have a ducted system running hard for months against sub-zero nights, so ducted heating is the biggest energy bill of the year in Canberra.
Is gas or reverse-cycle better for Canberra's cold?
Both are run hard. Ducted gas gives reliable heat on the coldest nights, but a modern reverse-cycle system is now strong too, with the caveat that a heat pump's efficiency falls on the very coldest nights, so the low-temperature rating matters in Canberra.
Does insulation cut the Canberra heating bill?
Strongly. Many ex-government homes are poorly insulated and leak heat, lifting the hours and the bill regardless of fuel, so insulation and draught-proofing pay back well, and zoning to heat only the rooms in use is the biggest single saving in Canberra.
Do I need a licence for ducted heating in Canberra?
Not to run it, but the install is licensed by fuel: a ducted gas system needs a licensed gas fitter, and a reverse-cycle system a refrigeration or ARC-certified technician and a licensed electrician, under Access Canberra for the electrical side.
