Cooling is one of the biggest contributors to a Brisbane summer power bill, especially when the air conditioner is running day after day to keep up with the heat and humidity. The good news is that you don’t have to sacrifice comfort to reduce your energy costs. A few simple changes can make a noticeable difference to how efficiently your air conditioner runs.
In this guide, you’ll discover five practical tips to help lower your air conditioning costs, improve your system’s efficiency and keep your home comfortable throughout Brisbane’s warmer months.
1. Set the temperature smartly
This is the easiest win, and most people get it wrong. Every degree cooler you set your aircon can add roughly 5 to 10 per cent to its running cost.
- Aim for 24 to 25 degrees in cooling mode.
- Resist the urge to crank it to 18 for a quick chill. The room does not cool any faster; the unit just runs harder for longer.
- If your unit has a timer or a sleep mode, use it overnight.
You will barely notice the difference in comfort, but your bill will.
2. Keep the filters and unit clean
When the filter is clogged, your air conditioner has to work harder to move cool air around your home. That extra strain can reduce cooling performance and increase energy use.
- Clean the filters every few weeks during heavy summer use.
- Keep the outdoor unit clear of leaves, cobwebs, and garden growth.
- Book a proper air conditioner clean in Brisbane once a year so the coils and internals are dealt with too.
A clean system runs more efficiently than a neglected one, which can help reduce your energy bills over time.
3. Seal the cool air in
There is no point cooling air that leaks straight outside. In a lot of Brisbane homes, this is where the savings are hiding.
- Close doors to rooms you are not using so you only cool the space you need.
- Shut blinds and curtains during the hottest part of the day to block the western sun.
- Check for draughts under doors and around windows and seal them up.
- Make sure the roof is properly insulated, since a lot of heat sneaks in from above.
Cooling three rooms instead of the whole house is a genuinely big saving over a long summer.
4. Let ceiling fans do some of the work
Fans are cheap to run, and they make a cooled room feel two to three degrees cooler by moving air across your skin.
- Run fans alongside the aircon so you can set the thermostat a touch higher for the same comfort.
- Make sure ceiling fans are spinning anticlockwise in summer to push air down.
- Turn fans off when you leave the room, since they cool people, not spaces.
This combination lets you lift the temperature setting without feeling any hotter, which is exactly where the savings come from.
5. Service it before summer starts
An unserviced aircon quietly gets less efficient every year. Low refrigerant, dirty coils, and worn parts all force it to run longer to hit the same temperature.
A yearly air conditioning service in Brisbane keeps it running the way it was designed to, and catches small faults before they become expensive breakdowns. Think of it like a service for your car. A little now saves a lot later.
A note on ducted systems
If you have ducted air conditioning, zoning is your best friend. Only cool the parts of the house you are actually using rather than the whole home at once. It is one of the simplest ways to keep a ducted system from dominating your bill.
And if your unit is more than ten to fifteen years old, no amount of tweaking will match a modern high-efficiency system. Sometimes upgrading is the real money saver.
Cool comfort without the bill shock
If you want to keep your home cool without sending your electricity bills through the roof, now is the ideal time to have your air conditioner checked before summer arrives. A professional service can improve efficiency, reduce running costs, and help prevent unexpected breakdowns during Brisbane’s hottest months.

FAQs
What temperature should I set my air conditioner to save money in summer?
A setting of 24°C to 25°C is suitable for most Brisbane homes. It keeps the house comfortable without making the air conditioner work harder than it needs to.
Does servicing my air conditioner reduce running costs?
In many cases, yes. A serviced air conditioner can cool your home more efficiently than one with dirty filters or worn parts, particularly during Brisbane’s warmer months.
Is it cheaper to leave the air conditioner on all day or turn it on and off?
For most homes, cooling only when you are there, using a timer to take the edge off before you arrive, works out cheaper than running it all day in an empty house.
Do ceiling fans really help lower air con costs?
They do. Fans let you set the thermostat higher for the same feeling of comfort, and they cost only cents an hour to run.
