Choose the right size air conditioner
When buying an air conditioner, choose a unit that is appropriately sized for the room or area you want to cool. An incorrectly sized system may not perform as efficiently as intended and could cost more to run.
Improve your home's insulation
Good ceiling insulation can help reduce heat entering the home and improve indoor comfort during summer. It can also reduce your reliance on air conditioning.
Service your air conditioner regularly
Regular maintenance helps your air conditioner operate efficiently. Clean the filters according to the manufacturer's instructions and arrange servicing when recommended. Dirty filters can restrict airflow and reduce performance.
Upgrade to an energy-efficient model
If your air conditioner is reaching the end of its useful life, replacing it with a newer, energy-efficient model may help reduce running costs. When comparing units, check the energy star rating and select a model suited to your needs.
Keep the cool air inside
Preventing cool air from escaping can help reduce the workload on your air conditioner.
- Keep curtains and blinds closed during the hottest part of the day.
- Seal gaps around windows and doors where cooled air can escape.
- Only cool areas of the home that are being used.
Keep the temperature consistent
Setting the temperature lower does not cool a room faster. The WA Government recommends setting air conditioners to no lower than 24°C in summer. It also advises that every degree below 24°C can increase energy costs by around 10%.
Make use of natural ventilation
When outdoor temperatures are cooler than indoor temperatures, opening windows and doors may help improve comfort and reduce the need for air conditioning.
Reduce indoor heat sources
Heat-generating appliances can make your air conditioner work harder.
- Limit use of ovens during the hottest part of the day.
- Turn off computers, gaming consoles and other electronic devices when they are not being used.
- Consider using outdoor cooking options, such as a barbecue, when weather conditions allow.
- If possible, use heat-generating appliances during cooler parts of the day.
Use a fan
Fans create airflow that can make people feel cooler, even though they do not reduce the actual temperature of a room. Using a fan alongside an air conditioner may allow you to remain comfortable at a higher temperature setting.
