What Temperature Should I Set My Air Conditioner In Summer?

Mulherin Air Conditioning Services • Oct 25, 2022

Summer is rapidly approaching, and with the intense heat just around the corner, many are likely to be looking for ways to regulate this temperature rise in the coming months. An air conditioning unit is perfect to help you bring the harsh heat down and give you a place of respite away from the stifling weather. However, there is also a lot of worries recently surrounding energy bills and soaring prices, so to help you work out what temperature to set your air conditioner to, read on for more information.

What Temperature Should I Set My Air Conditioner To In The Summer?

There are various answers to this depending on the area of Australia that you live in. This is because the average temperatures vary from place to place. Of course, you need to stay cool and have somewhere to get out of the burning sun, but you also need to balance this with the cost of energy. So, here are the temperatures it is best to opt for depending on the state you live in.

  • North Queensland, North West Australia, Northern Territory, and central Australia should opt for around 21-23°C
  • Western Australia's South West residents should set their air con to 23 or 24°C
  • South Victoria residents should choose 24°C on their air con units
  • South Australia can set their machines to 24 or 25°C
  • South East Queensland and North East NSW would benefit from setting air con units to 25°C
  • South East NSW, North East Victoria and Australian Capital Territory should choose 26 or 27°C
  • Tasmania residents should opt for a higher 28°C

How To Save Money On Your Energy Bills

There are a few things you can do to make sure your air conditioning unit is doing the optimum amount of work and using the least amount of energy to keep you cool. 


One important factor is the size of your unit. You need to choose the size carefully since having a unit that is too big will waste lots of energy. On the other hand, a unit that is too small will force the machine to work too hard and therefore wear down parts much more quickly, making it less cost-efficient due to the repair work it will require. If you are unsure of what is best for your home, you would benefit from contacting a professional who can help you to pick out the best option for your house. 


It can also help to clean your filters regularly and to use ceiling fans to avoid overworking your air-con. You should also avoid running the unit all day and utilise the various operating modes. This will ensure your machine is working optimally and you aren't wasting money by keeping your A/C on when you're not at home. 


If you're considering getting a new system installed, it may be worth looking into a split system, which allows you to cool individual rooms rather than the whole house.
