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 Perth
Ducted heating cost in Perth is modest, because the hot, dry Mediterranean climate has a short, mild winter, so heating runs for only a few weeks and the bill is small next to the southern capitals. The fuel splits the same way, ducted gas billed by the gas burned and reverse-cycle billed by the power drawn, but with so few heating hours the choice matters less in Perth than in a cold city, and many homes simply use the heating side of a reverse-cycle system installed for the fierce summer cooling.
Because the summer cooling load dominates the Perth year, a reverse-cycle system is the natural choice and its winter heating is a light, cheap addition, so a dedicated ducted gas heater is harder to justify than in Melbourne. Where a home does have gas ducted, rising gas prices have eroded its running-cost edge. Zoning the heating to the rooms used on a cold morning is the main saving on an already small bill. Perth's double-brick walls hold warmth once a home is heated, cutting the hours, and the isolation of the WA market affects servicing lead time more than the running cost.
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 WA Building Services for the electrical side. For a Perth home, the clearest way to think about ducted heating cost is the fuel times the few weeks the mild Mediterranean winter demands, usually covered cheaply by reverse-cycle.
