Heating and cooling rebates in Northern Territory
No heating season at all, and cooling that costs more than most people's whole bill.
What you can claim towards heating or cooling in Northern Territory, what the systems actually cost to run here, and the local facts that change the answer — the climate, the tariff structure and the grid.
What you can claim in Northern Territory
There is nothing available in Northern Territory
Northern Territory runs no state rebate for heating or cooling, and there is no federal scheme either — Small-scale Technology Certificates cover water heaters and solar panels only. So unlike a hot water upgrade, where every Australian gets $800 to $1,200 regardless of postcode, there is no national floor here.
That is the complete answer as at 5 September 2026, and it is worth stating plainly rather than burying.
Why Northern Territory is different
The Northern Territory has no state rebate for heating or cooling and no federal one, so nothing is available.
It is also the only Australian jurisdiction with no heating season whatsoever — zero heating degree days against 3,508 cooling. Every dollar of space conditioning in Darwin is cooling, which makes it the mirror image of every southern capital and means most national advice about heating systems is simply irrelevant here.
Two consequences worth acting on. Evaporative cooling does not work in Darwin's humidity, so the dry-climate advice that suits Perth and Adelaide is actively wrong here — it is refrigerated cooling or nothing. And because cooling runs almost year-round rather than for a season, the efficiency star rating on the unit matters more in the Northern Territory than in any other market. A one-star difference compounds over 3,508 degree days rather than a few hundred.
What it costs to heat and cool a house here
A 160 m² house built before 2005, heated and cooled for a full year at Northern Territory's reference rates. On these assumptions the cheapest option in Northern Territory is single split system at about $569 a year — though read the conditions column, because it is not conditioning the same amount of house as the ones below it.
| System | Conditions | Per year | Installed | 10-year total |
|---|---|---|---|---|
| Single split system | One main living area | $569 | $2,600 | $8,287 |
| Multi-split system | Most of the house | $1,295 | $8,500 | $21,450 |
| Ducted reverse cycle | The whole house | $1,858 | $15,500 | $34,079 |
| Electric panel or fan heater | Heats only — you would still need something for summer. | |||
| Gas space heater | There is no reticulated natural gas in the Northern Territory. | |||
| Ceiling fans | Cools only — you would still need something for winter. | |||
| Ducted gas heating | There is no reticulated natural gas in the Northern Territory. | |||
| Ducted evaporative cooling | Cools only — you would still need something for winter. |
A 160 m² pre-2005 house in Northern Territory — 0 heating and 3,508 cooling degree days — at 31.7c/kWh, heating and cooling for a full year. Read the conditions column: the cheap options are partly cheap because they condition less of the house.

There is no federal rebate for heating or cooling. Small-scale Technology Certificates apply to water heaters and solar panels only, so unlike a hot water upgrade there is no national floor — what you get depends entirely on your state. Every figure is indicative and delivered as a discount by an accredited installer rather than claimed back. Last verified 5 September 2026.
Frequently asked questions
What air conditioning rebate can I get in Northern Territory?
None. Northern Territory has no state scheme and there is no federal rebate for heating or cooling, so there is nothing available regardless of what system you choose or who installs it.
Is Darwin a heating or a cooling climate?
0 heating degree days against 3508 cooling, so decisively a cooling climate — buy for summer, and treat winter performance as a secondary consideration.
How much does it cost to run a ducted system in Northern Territory?
About $1,858 a year for a 160 m² pre-2005 house at 31.7c per kilowatt hour, heating and cooling combined. A multi-split in the same house comes to about $1,295, but it is conditioning less of the house — that is most of the difference, not better hardware.
Would insulation save more than a new system in Northern Territory?
Almost certainly. Taking the same house from pre-2005 to a 6-star standard cuts heating energy to 30% and cooling energy to 60% — a bigger reduction than any system change on the market, and it applies whichever system you end up with. No scheme in Northern Territory pays for it, which is precisely why it gets overlooked.
