It can cost a lot of money for Australia homeowners to run an air conditioner, especially during the hot summer months. Australia has very expensive electricity, so it's essential for homeowners to know how much it costs for them to operate an air conditioner and how they can thrive in comfort while saving. In this article, the cost of running an AC in Australia will be laid out, as well as tips on how to bring these costs down.

Understanding the Costs

The cost to operate an air conditioner in Australia varies but is influenced by factors such as the type of unit, its size, energy rating and the cost of electricity in the local area. On average, a standard reverse cycle air conditioner meant to be used in cooling mode for approximately 4 hours per day in the summer months will cost around $150 - $300 for the season. However, less efficient models or extended use can mean the charges can be higher.

Tips for Reducing Air Conditioning Costs

Upgrade to Energy-Efficient Models: Modern air conditioners are much more energy-efficient. Look for models with a high Energy Star Rating. A unit with more stars is generally more efficient and less expensive to run, oftentimes saving a household a significant amount over the life of the unit.
Smart Thermostat Use: Setting your thermostat at 24-25 degrees Celsius or comfortable but reasonable temperature will help your AC work less. According to the Department of Energy, setting the temp at 24-25 degrees Celsius when you’re home is a good balance between comfort and efficiency. For every degree lower, you use about 10 per cent more energy.
Routine Maintenance: Proper maintenance of your air conditioning unit ensures optimal performance. Replace or clean air filters periodically; inspect condenser coils each year; and do not allow dust or debris to block air flow.
Set Timers and Programmable Settings: Many air conditioners have timers or other programmable settings. If you use these, you can reduce the amount of time you use your AC, by automatically turning off your AC during times of the day when cooling is not needed, such as at night or when no one is home.
Improve Home Insulation: Improving your home insulation ensures cool air stays in and warm air stays out, reducing the burden on the air conditioning unit to work hard. Consider double-glazing windows, insulating your roof, and sealing any cracks that might appear around doors and windows in order to enhance energy retention.
Leverage passive cooling: Before you even turn on your AC, look for ways to cool your home using natural means. Cool your home by opening the windows for ventilation. Cover windows with drapes to shade the interior during the hottest parts of the day. Keep the air moving with ceiling fans, and that should delay, if not reduce, the need to run your AC altogether.
Zone the Air: If your home and air conditioning system support zoning, cool only the parts of the home that are occupied. If you are not using a room, there is no need to cool it.


It is possible, for example, to run an air conditioner in Australia without breaking the bank. By taking account of the variables that make a difference to running costs, and by employing some ingenious ways to improve efficiency, even those in the land down under can stay cool without breaking the bank – or the planet. Through purchasing energy-efficient models, keeping your unit well-serviced and finding some smart ways to cool your home, you can make significant savings.
