Australia has pretty long summers with 32 degrees Celsius as an average temperature. According to a study, around 4.6 million Australians have at least one AC unit at their home. 

Running the air conditioner for a long time can result in huge electric bills. Heating and cooling expenses in Australia can account for up to 50% of the home energy budget. 

Besides blasting cold air, air conditioners remove harmful pollutants from the indoor air and minimises the irritants that trigger asthma and other breathing diseases. 

By utilising the following ideas in your daily life, you can save your hard-earned money on utility bills, and also protect the environment: 

  1. Choose Energy Star Rating Air Condition

The energy star rating not only helps you reduce your summer bill but also reduce greenhouse emissions. An AC with more number of stars utilises less energy.

A certified star rating air conditioner uses approximately 15% less energy as compared to non-certified models. That 15% could save you nearly $90 over the unit’s lifetime. 

A proper air conditioning installation can also help in 

  • Reducing The Possibility Of Asthma Attacks
  • Making Your Home More Secure
  • Improving The Work Performance
  • Protecting Your Home From Insects And Parasites
  • Reducing The Risk Of Dehydration
  1. Check For Thorough Home Insulation

Air leakage can cause the conditioned air to leave your house through small cracks and openings, making ventilation costly. Reducing the flow of air leaking from your home can maximise the efficiency of your air conditioning system. 

Weather-stripping and caulking are the two most practical and useful air-sealing routines that offer quick results after investing. It can significantly reduce your home’s energy usage through more efficient heating and cooling.

  • Weather-stripping is used to seal movable and operational building components, such as doors and operable windows. They are ideal for areas prone to expansion and contraction. It also provides soundproofing to your home.
  • Caulk is utilised to fill the small cracks and openings, such as window frames and around the door. 

Both are almost the same with a little difference that caulk is rigid when dry and weather-stripping is a more flexible material such as silicone.

  1. Turn Off AC When Not In Use

By keeping your air conditioner working during the day and turning off at night can make a significant impact on your electricity bill. The evening air is naturally more refreshing, so turn off your AC unit, open a window and enjoy the gentle breeze to cool things down.

Also, your body doesn’t need an air conditioner for comfortable sleeping. So, with your AC off, you can have some sweet dreams with nocturnal energy savings. Also, you can set the timer to turn off the AC shortly after bedtime.

  1. Clean Your Air Conditioner Vents And Units

For efficient working, an air conditioning unit needs time to time service and repair. Fins, coils, and filters must be maintained regularly for good air movement.

  • Replacing an old filter with a clean one can minimise the energy consumption of your air conditioner by 10 to 18%. 
  • Dirty and clogged filters will obstruct airflow and decrease the efficiency of the system.
  • Dirt and debris can block natural airflow and perhaps impair the evaporator. 

To get better results, leave it to professionals for air conditioning service and repair

A Licensed Technician Should:

  • Use Proper Equipment And Tools 
  • Verify The Correct Electric Control Sequence
  • Remove Debris And Clean The Fins
  • Inspect Electrical Terminals And Apply A Non-conductive Coating, If Necessary
  • Straighten The Fins
  • Level The Unit For Proper Water Drainage
  • Measure Airflow And Clean The Evaporator Coil
  • Clean A Clogged Evaporator Drain
  • Change The Blower Filter
  1. Turn off heat-emitting Devices

The wifi router, lamp in the corner, printer, computer, television, etc. all conventional household devices generate a plethora of heat. This heat will force your air conditioner unit to work harder to keep the temperature under control. You’ll save money on your AC energy consumption, by turning off the heat emitting devices or minimise their usage.

Also, don’t use your oven or stovetop during hot spells. You can reduce the indoor heat by switching to an outdoor grill, cooking meals in the microwave, or eating fresh food, such as fruits and salads. 

Turn on the exhaust fan of the kitchen and bathroom after every cooking and a hot shower respectively to help the heat dissipate.


These tips will not only keep the AC and your health right but also reduces the electricity bill, which ultimately helps you save the indoor environment.
