Your estimate sits within the typical range.
Ducted running cost depends on the system's power draw (not just its size rating), hours run, your electricity tariff, and insulation. Zoning and a good thermostat setting are the biggest levers you control.
Ways to save
- Use zoning to cool or heat only the rooms you are in, the biggest single saving.
- Set the thermostat sensibly, each degree closer to outside temperature cuts running cost noticeably.
- Good insulation and sealing reduce the load, so the system runs less to hold the temperature.
How we estimate this
Running ducted air conditioning in Australia typically costs around $2 to $6 per hour in 2026 for an average home at current electricity prices, so a few hours a day is often $4 to $15. Large systems, long hours and no zoning push it higher.

What a ducted air conditioning running costs in Adelaide
The running cost of ducted air conditioning in Adelaide is the electricity used to cool, the kilowatt-hours drawn times your tariff, and it spikes through the hot, dry Mediterranean summer when Adelaide's run of very hot days, among the hottest of the capitals, has a refrigerated ducted system working flat out. South Australia's electricity tariffs are high, so even though the servicing labour is the cheapest of the mainland capitals, the power itself makes a hard-run summer a notable bill.
Like Perth, Adelaide's dry climate makes ducted evaporative cooling a viable, cheaper-to-run alternative to refrigerated for much of summer, so many homes pair evaporative for ordinary hot days with refrigerated for the most extreme, humid ones. Zoning a refrigerated system to the rooms in use is the main lever on the bill. Adelaide's older stone cottages with thick walls hold the cool well and can cut the cooling hours, while a lightweight modern home leans harder on the system. The affordable local labour keeps a service or repair cheap even if the power is not.
Running the system is just paying for power, with no licence needed, but installing or servicing ducted cooling is licensed: a licensed refrigeration or ARC-certified technician handles the refrigerant and a licensed electrician the wiring, under Consumer and Business Services for the electrical side, while an evaporative unit's water connection is plumbing. For an Adelaide home, the clearest way to think about the running cost is kilowatt-hours times the high local tariff, with evaporative a cheaper-to-run option and zoning the main saving.

Is servicing cheap in Adelaide even if power is not?
Yes. The affordable local labour that marks the city out keeps a service or repair the cheapest of the mainland capitals, even though the high electricity tariff makes the actual running of a refrigerated ducted system dear in Adelaide.
Is evaporative cooling an option in Adelaide?
Yes. Adelaide's dry climate makes ducted evaporative cooling a viable, cheaper-to-run alternative to refrigerated for much of summer, so many homes pair evaporative for ordinary hot days with refrigerated for the most extreme ones.
