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 Adelaide
Ducted heating cost in Adelaide turns on the fuel, because the cool winters mean real, if not extreme, heating demand, so whether a home runs ducted gas billed by the gas burned or reverse-cycle billed by the power drawn makes a genuine difference to the bill. South Australia's energy is dear on both fronts, with high electricity tariffs and rising gas prices, so efficiency matters even though the affordable local labour keeps the install and servicing the cheapest of the mainland capitals.
Ducted gas heating has been common in Adelaide's cooler homes, but as with Melbourne the rising gas price and improving reverse-cycle efficiency have made a modern reverse-cycle system a serious contender on running cost, with the bonus of summer cooling for the hot, dry Mediterranean summers. The star rating of a gas furnace and the efficiency rating of a reverse-cycle unit each decide how dear the heat is. Adelaide's thick-walled stone cottages hold warmth and cut the hours, while a lightweight home leans harder on the system. Zoning to heat only the rooms in use is the main saving against a dear tariff.
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 Consumer and Business Services for the electrical side. For an Adelaide home, the clearest way to think about ducted heating cost is the fuel and its efficiency times the cool-winter hours, with gas versus reverse-cycle a live call against dear energy.

Frequently asked questions
What determines ducted heating cost in Adelaide?
The fuel. The cool winters mean real heating demand, so ducted gas billed by the gas burned versus reverse-cycle billed by the power drawn makes a genuine difference, and South Australia's dear energy on both fronts makes efficiency matter in Adelaide.
Is gas or reverse-cycle better in Adelaide?
It is a live call. Rising gas prices and improving reverse-cycle efficiency have made a modern reverse-cycle system a serious contender on running cost, with the bonus of summer cooling for Adelaide's hot, dry Mediterranean summers.
Does cheap labour offset dear energy in Adelaide?
Partly. The affordable local labour keeps the install and servicing the cheapest of the mainland capitals, but the high electricity tariff and gas price mean the system's efficiency is where the real running-cost saving sits in Adelaide.
Do I need a licence for ducted heating in Adelaide?
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 Consumer and Business Services for the electrical side.
