Stay Cool & Save Energy: The Best AC Temperature for Western Australia Summers
Summers in Western Australia can be scorching, and the last thing you want is an uncomfortable home or sky-high electricity bills. Setting your air conditioner correctly is key to keeping cool without breaking the bank.
But what is the best air conditioner temperature for summer in WA? If you’re in Perth, Albany, Bunbury, Mandurah, or anywhere across WA, this guide will help you find the ideal AC setting while maximising efficiency.
What is the Ideal Temperature for Your AC in Summer?
Energy experts recommend setting your air conditioner between 24-26°C during summer.
Why? Because this range keeps your home comfortable while ensuring energy-efficient cooling. Lowering your AC below 24°C increases power consumption by 5-10% per degree, which can significantly impact your electricity bills.
For coastal areas like Perth, Busselton, and Geraldton, humidity can make temperatures feel warmer. Your AC helps dehumidify the air, so keeping it at 24-26°C is the most efficient option.
Factors That Affect the Best AC Temperature in WA
1. Western Australia’s Climate
Western Australia experiences hot summers with dry and humid conditions, depending on the region. If you live in Perth or the southwest, you’ll likely experience high humidity, making it feel hotter indoors. In contrast, areas like Kalgoorlie or the Pilbara have dry heat, where an AC may not need to work as hard.
2. Insulation & Home Design
A well-insulated home retains cool air longer, reducing the workload on your AC. If your house has poor insulation, your aircon will struggle to maintain the set temperature, increasing energy use. Sealing gaps, using block-out curtains, and upgrading insulation can make a big difference.
3. How Many People Are in Your Home?
More people generate more body heat, so homes with multiple occupants may need better airflow or slight temperature adjustments. Using ceiling fans can help distribute cool air, reducing the need to lower the AC temperature.
4. The Efficiency of Your Air Conditioner
Older or poorly maintained AC units often struggle to cool efficiently. If your aircon isn’t keeping up, it may need cleaning, servicing, or an upgrade to a more energy-efficient model.
How to Set Your AC for Maximum Efficiency
Want to stay cool without spending a fortune? Here are some proven strategies to maximise your AC’s performance:
✅ Use Ceiling Fans
Fans help circulate cool air, allowing you to raise the thermostat by 1-2°C without feeling the difference.
✅ Close Curtains & Blinds During the Day
Blocking direct sunlight prevents indoor heat buildup, helping your AC maintain an optimal temperature with less effort.
✅ Set a Higher Temperature When You’re Away
If you’re leaving home, increase the thermostat to 27-28°C to save energy. A smart thermostat can automate this process.
✅ Regularly Service Your Air Conditioner
Dirty filters and clogged vents force your AC to work harder. Routine maintenance from Adam Taylor Electrical ensures your unit runs efficiently all summer.
✅ Seal Gaps & Insulate Your Home
Prevent cool air from escaping by sealing doors, windows, and ducts. This reduces strain on your aircon, improving its performance.
Is a Smart Thermostat Worth It?
Yes! A smart thermostat allows you to adjust AC settings based on the time of day.
For example:
- During the day: Set it at 24-26°C while at home.
- At night: Increase it slightly to 26-27°C for comfortable sleeping.
- When you’re away: Raise it to 27-28°C or turn it off to conserve energy.
A smart thermostat can help homeowners in Perth, Bunbury, Mandurah, and other WA regions reduce energy waste while staying cool.
