As the Australian summer approaches, staying cool without skyrocketing energy bills becomes a priority for many households. While air conditioners are essential for comfort during sweltering days, optimising their use is key to balancing efficiency, cost, and environmental impact. Here’s how to get the most out of your air conditioner without compromising on comfort or budget.
Choose the Right Temperature
One of the simplest ways to optimise your air conditioner is by setting the temperature correctly. For most Australians, the ideal indoor temperature during summer is around 24–26°C. This range keeps your home cool without placing unnecessary strain on your unit or energy bills.
Every degree lower than this can increase energy usage by up to 10%, so avoid the temptation to crank the AC to arctic levels. Instead, focus on maintaining a comfortable, consistent temperature that suits the season.
Use a Programmable Thermostat or Timer
A programmable thermostat or timer can significantly improve efficiency. Many air conditioners allow you to set schedules, ensuring the unit only operates when needed. For example, you can program it to turn on just before you return home from work and switch off after bedtime.
This feature eliminates the need to run your air conditioner all day, reducing wear and tear and saving on energy costs.
Maximise Airflow and Circulation
Your air conditioner will work more effectively if your home is set up for optimal airflow. To achieve this:
- Keep vents clear: Ensure furniture or curtains aren’t blocking air conditioning vents.
- Use fans: Ceiling or portable fans can circulate cool air more effectively, allowing you to set your AC at a slightly higher temperature.
- Close doors and windows: Seal off the cooled space to prevent hot air from seeping in.
By improving air circulation, you can create a more evenly cooled environment without overworking your air conditioner.
Maintain Your Air Conditioner
Routine maintenance is vital for keeping your air conditioner running smoothly. Here are the main maintenance tasks to consider:
- Clean or replace filters: Dirty filters restrict airflow, forcing your unit to work harder. Clean or replace them every one to three months.
- Check the outdoor unit: Ensure the external condenser is free of debris like leaves, dirt, or grass clippings.
- Schedule professional servicing: Regular check-ups by a licensed technician can identify and fix potential issues before they escalate.
A well-maintained air conditioner will operate more efficiently, last longer, and reduce energy consumption.
Leverage Energy-Saving Features
Modern air conditioners often come with energy-saving features. Familiarise yourself with these options to optimise performance:
- Eco Mode: Reduces power consumption by adjusting cooling intensity.
- Sleep Mode: Gradually raises the temperature overnight to conserve energy while you sleep.
- Inverter Technology: If you’re in the market for a new unit, choose one with inverter technology. These models adjust power usage based on the room’s temperature, offering greater efficiency.
Using these features strategically can make a noticeable difference in your energy bills.
Reduce Heat Inside Your Home
The less heat your air conditioner has to combat, the more efficiently it can operate. Take steps to minimise indoor heat:
- Block sunlight: Use blinds, curtains, or reflective window films to reduce solar heat gain.
- Limit heat-producing activities: Cook outdoors, use the microwave instead of the oven, and switch to energy-efficient LED lighting.
- Insulate your home: Proper insulation keeps cool air in and hot air out, making your air conditioner’s job easier.
By reducing the heat load, you can maintain a comfortable indoor environment with less energy usage.
Only Cool the Spaces You Use
Cooling your entire home isn’t always necessary. Focus your air conditioner on the rooms you spend the most time in. Shut doors to unused rooms and consider using zoned cooling systems, which allow you to target specific areas.
This approach reduces energy waste and ensures your air conditioner works efficiently where it matters most.
Avoid Overworking Your Air Conditioner
While it’s tempting to leave your air conditioner running continuously during a heatwave, doing so can strain the unit and increase energy costs. Instead, use these tips to minimise reliance on your AC:
- Cool down at night: Open windows in the evening to let in cooler air.
- Use dehumidifiers: Reducing humidity can make the air feel cooler, even at higher temperatures.
- Take advantage of natural ventilation: Open windows and doors early in the morning when the air is still cool.
These strategies can complement your air conditioner and reduce the hours it needs to operate.
Upgrade to an Energy-Efficient Model
If your current air conditioner is outdated, consider upgrading to an energy-efficient model. Units with a high Energy Star rating use less power and are better for the environment.
Although the upfront cost may be higher, the long-term savings on energy bills make it a worthwhile investment. Plus, newer models often come with advanced features that enhance comfort and efficiency.
Monitor Your Energy Use
Understanding your energy consumption is essential for optimising your air conditioner. Many energy providers in Australia offer usage tracking tools or apps that show how much power your household consumes daily.
Use this information to identify patterns and adjust your habits. For instance, you might find opportunities to run your air conditioner less during certain times of the day without sacrificing comfort.
Stay Cool and Save
Optimising your air conditioner isn’t just about cutting costs—it’s also about creating a comfortable living space that’s environmentally responsible. By following these tips, you can enjoy the benefits of a cool home without worrying about excessive energy bills or unnecessary strain on your AC unit.
