Staying cool during Perth’s hot summers can be a challenge, especially when energy bills begin to rise. Fortunately, there are many ways to enjoy a comfortable indoor environment without overspending. By adopting energy efficient cooling strategies and choosing the right system, Perth homeowners can reduce costs and maintain comfort.
At WestOz Trades Air Conditioning Services, we help locals find the right balance between cooling performance and energy savings. Below are practical ways to reduce aircon power bills while keeping your home cool, even on the hottest Western Australian days.
Select an Energy Saving Air Conditioning System
One of the most effective ways to lower cooling costs is by investing in a modern and energy saving air conditioning unit. Systems that include inverter technology adjust power usage according to the room’s temperature, offering both reduced energy consumption and consistent comfort.
When installing or upgrading a system, always check the Energy Star rating. A higher rating indicates better efficiency. Trusted brands such as Mitsubishi, Daikin and Panasonic offer top-performing systems that work well in Perth’s climate.
Set Your Thermostat for Greater Efficiency
Small thermostat adjustments can have a big impact on power usage. For energy efficient cooling in Perth, aim to keep your air conditioner set between 24 and 25 degrees Celsius when you are at home. Lower settings do not cool the space more quickly but will lead to significantly higher electricity use.
Using a programmable thermostat or timer ensures your home is only cooled when necessary, which helps prevent unnecessary energy use.
Insulate and Seal to Keep the Cool Air In
Good insulation is essential for low cost aircon solutions in Perth. Adding insulation to your roof, walls and flooring helps maintain a consistent indoor temperature, easing the demand on your air conditioning system.
Sealing gaps around windows and doors also helps keep the cool air inside. Simple solutions such as draught stoppers, thick curtains and window seals can greatly improve your home’s energy performance.
Use Ceiling Fans to Assist with Cooling
Ceiling fans use significantly less energy than air conditioners and help by circulating air throughout the space. Although they do not lower the actual room temperature, they create a cooling effect, allowing you to raise the thermostat setting slightly without losing comfort.
This is one of the most accessible AC efficiency tips Perth homeowners can put into practice right away.
Keep Sunlight Out to Reduce Heat
Direct sunlight can quickly raise indoor temperatures. Installing blinds, curtains or reflective window film helps block out heat and keep your home naturally cooler.
This is especially beneficial for homes with large windows that face west, making it an effective strategy to cool your home cheaply in Perth without over-relying on your air conditioner.
Maintain Your Air Conditioning System Regularly
Even the most efficient system will lose performance over time without regular maintenance. Dusty filters, obstructed vents and worn parts make your unit work harder and use more energy.
Regular servicing by a professional—such as our team at WestOz Trades—ensures your system runs efficiently and maintains peak performance.
Make Use of Zoned Cooling Where Available
If your system supports zoned cooling, use it to focus on the rooms you are actively using. This allows you to minimise energy use without compromising comfort. It is one of the most effective and often overlooked low cost aircon solutions in Perth, especially for larger homes.

Frequently Asked Questions
What is the most energy efficient way to cool a home in Perth?
The most energy efficient approach combines a modern inverter air conditioning system, correct thermostat settings between 24 and 25 degrees, good insulation, and regular maintenance. Using ceiling fans and blocking direct sunlight can further reduce cooling costs.
Does setting the air conditioner lower cool the house faster?
No. Setting the thermostat lower does not cool the space faster. It only forces the system to work longer, increasing energy use and power bills without improving comfort.
Are ceiling fans effective for reducing air conditioning costs?
Yes. Ceiling fans use far less electricity than air conditioners and improve air circulation. This allows you to raise the thermostat slightly while still feeling cool, reducing overall energy consumption.
How important is insulation for energy efficient cooling?
Insulation plays a major role in keeping cool air inside the home and reducing heat transfer. Well insulated roofs, walls, and sealed windows significantly reduce the workload on air conditioning systems.
How often should air conditioning be serviced for best efficiency?
Air conditioning systems should be professionally serviced at least once a year. Regular servicing ensures filters, coils, and components remain clean and efficient, helping to lower running costs and extend system lifespan.
