Heatwaves in Australia can push our air conditioning systems to their limits, driving up energy costs and testing the reliability of these essential devices. However, with the right strategies, you can ensure your air conditioner runs efficiently even during the hottest days of summer. Here are the top ways to improve air conditioner efficiency during heatwaves:
Regular Maintenance and Servicing
One of the most effective ways to keep your air conditioner running smoothly is through regular servicing. Over time, filters can become clogged, coils may accumulate dust, and small parts can wear out, leading to inefficiency and higher energy bills. Scheduling regular maintenance ensures these issues are addressed before they become costly problems.
If you’re looking for expert maintenance, consider booking an air conditioning service in Fremantle. A professional technician can clean and inspect your system, ensuring it’s ready to take on the demands of summer.
Set the Thermostat at an Optimal Temperature
It can be tempting to set your thermostat to the lowest possible temperature during a heatwave, but this forces your air conditioner to work harder than necessary. For optimal efficiency, set the thermostat to around 24–26 degrees Celsius. Every degree lower than that can increase your energy consumption by as much as 10%. Additionally, using a programmable thermostat allows you to adjust the temperature based on when you’re home, saving energy when the house is empty.
Seal Leaks and Insulate Your Home
An efficient air conditioning system can only do so much if your home isn’t properly sealed. Check windows, doors, and even electrical outlets for any air leaks that could let cool air escape. Using weather stripping or caulking to seal these gaps will keep the cool air inside and reduce the workload on your air conditioner.Similarly, proper insulation in your roof and walls can have a significant impact on how well your home retains cool air. During a heatwave, insulating your home helps your air conditioner maintain a steady temperature without constantly running at full power.
Use Fans to Help Circulate Cool Air
While fans don’t lower the temperature of a room, they can help circulate the cool air produced by your air conditioner. Ceiling fans or portable fans can spread the cool air more evenly throughout your space, allowing you to set your air conditioner at a higher temperature without sacrificing comfort. This small adjustment can result in big savings on your energy bill.
Close Curtains and Blinds During the Day
Direct sunlight streaming through windows can quickly heat up a room, causing your air conditioner to work harder to maintain a cool temperature. During the hottest parts of the day, close curtains and blinds to block out the sun’s rays. For even more efficiency, consider using reflective or blackout curtains, which are designed to reduce the amount of heat that enters your home.
Keep Vents and Filters Clean
Clogged filters and blocked vents can significantly reduce your air conditioner’s efficiency. Dust and debris can build up over time, restricting airflow and making your system work harder to cool your home. Make it a habit to clean or replace your filters every one to three months, especially during the summer. Likewise, ensure that nothing is obstructing your vents, such as furniture or curtains, to allow for smooth airflow.
Use the ‘Auto’ Fan Setting
Many air conditioners come with a fan setting that allows you to run the fan continuously or set it to ‘auto.’ Using the ‘auto’ setting ensures that the fan only runs when the air conditioner is actively cooling, which can save energy. Running the fan continuously may improve airflow but can also increase your energy consumption without providing additional cooling benefits.
Shade Your Outdoor Unit
Your air conditioner’s outdoor unit works more efficiently when it’s shaded from direct sunlight. Placing your unit in a shaded area or installing a small cover can help lower the unit’s temperature, improving its efficiency. Just ensure there’s enough space around the unit for proper airflow.
Upgrade to a High-Efficiency Model
If your air conditioner is more than 10 years old, it may be time for an upgrade. Modern air conditioning systems are significantly more energy-efficient than older models, especially those with a high Energy Star rating. While the initial investment may be higher, the long-term savings on your energy bill and the improved performance during heatwaves make it worth the cost.
Reduce Heat-Producing Activities During Peak Hours
During a heatwave, avoid using heat-generating appliances like ovens, stoves, and dryers during the hottest parts of the day. These appliances can quickly increase the temperature in your home, causing your air conditioner to work harder. Instead, try cooking outside on a barbecue or using smaller appliances like microwaves or slow cookers.
Enjoy a cool, refreshing summer
Improving your air conditioner’s efficiency during a heatwave doesn’t have to be complicated – with regular maintenance, thoughtful temperature control, and smart home adjustments, you can keep your home cool while reducing your energy bills.
