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 Darwin
Ducted heating cost in Darwin does not exist in any practical sense, because the tropical climate never gets cold enough to need heating, so no Darwin home installs ducted heating and the fuel question of gas versus electric simply never arises. Where every southern city weighs a heating bill, Darwin's concern is the opposite, a year-round cooling load, and even the coolest dry-season nights are mild enough that a blanket, not a heater, is all anyone reaches for.
This makes Darwin the one capital where ducted heating is a non-topic: a home's entire climate spend goes on cooling and dehumidifying through the wet-season build-up and the long hot months, and there is no winter heating season to add to it. A reverse-cycle air conditioner installed in Darwin is run purely for cooling, its heating mode effectively never used, so the heating efficiency rating that matters so much in Canberra or Hobart is irrelevant here. The remoteness and the salt-and-humidity corrosion shape the cooling system's cost and servicing, not any heating need.
Since there is no heating to run, no running-cost licence question arises, but for completeness any gas appliance a home does have must be connected by a licensed gas fitter and any reverse-cycle system installed by a licensed refrigeration or ARC-certified technician and a licensed electrician, under NT Building Practitioners licensing for the electrical side. For a Darwin home, the clearest way to think about ducted heating cost is that there is none to speak of, with the whole climate budget going to year-round cooling instead.

Frequently asked questions
Do Darwin homes have ducted heating?
No. The tropical climate never gets cold enough to need heating, so no Darwin home installs ducted heating and the fuel question of gas versus electric simply never arises, unlike every southern city.
What replaces a heating bill in Darwin?
A year-round cooling load. A home's entire climate spend goes on cooling and dehumidifying through the wet-season build-up and the long hot months, and even the coolest dry-season nights are mild enough that a blanket, not a heater, is all anyone needs in Darwin.
Is a reverse-cycle system's heating mode used in Darwin?
Effectively never. A reverse-cycle air conditioner in Darwin is run purely for cooling, so the heating efficiency rating that matters so much in Canberra or Hobart is irrelevant, and the corrosion and remoteness shape the cooling cost instead.
Do I need a licence for heating in Darwin?
There is no heating to run, but for completeness a gas appliance must be connected by a licensed gas fitter and a reverse-cycle system installed by a refrigeration or ARC-certified technician and a licensed electrician, under NT Building Practitioners licensing.
