What Temperature Should I Set My Air Conditioning For?

What a good temperature for air conditioning is will depend on the season you’re in, how hot or cold your body temperature generally runs to, and whether you’re focusing more on your comfort levels or keeping costs down. Setting your air conditioner at the right temperature can have a positive impact, not just on the performance and economy of your system, but also your health. 

What temperature should air conditioning be set at?

Even within the season, there is a range of ideal temperatures, which takes into account the varying body temperatures and needs of different people. 

What temperature to set air conditioner in summer in Australia?

For those looking to achieve a comfortable temperature in their home during a long hot Australian summer, we recommend setting your air conditioner to between 22C and 24C, depending on how much of an issue budget is. 

The cooler you set your temperature, the harder your air conditioning unit will have to work. Every extra degree is estimated to add 5-10% to your energy consumption, which means more energy usage, and higher bills. 

If you’re looking to save energy , while maintaining a cooler home, we suggest between 25C and 27C in the summer. Although this won’t provide the crisp cool that the truly hot blooded might crave, it will keep your home cool without breaking the bank. 

What temperature to set air conditioner in winter in Australia?

In the winter, a good temperature for air conditioning on a reverse cycle heating should be between 18C and 20C. The cooler your air conditioner, the lower your bill will be, so it depends how many jumpers and blankets you want to rug up in. Seriously, a temperature of between 18C and 20C should warm your house up, without sending your bill soaring. 

What temperature should my air conditioner be when sleeping?

The temperature of your bedroom can make or break your sleep quality. As your body’s temperature naturally drops when you’re sleeping (due to the reduced physical activity), a cooler room makes it easy for you to stay asleep. 

While the precise temperature for a good night’s sleep may vary from person-to-person, 16C to 20C is widely recognised as the best air con temp for sleeping.  Regulating your room at that temperature during the night will increase your restful sleep, which will have a positive impact on your health. 

Why does the temperature matter?

Setting your air conditioner at the right temperature matters a great deal, not just to your bills, but also to the system itself. 

It helps with air conditioner efficiency

The harder your system has to work – by warm temperature settings in winter and cool temperature settings in summer – the more frequently it may need servicing or repairs. Over time, it’s also likely to grow less energy efficient, and its performance might suffer.

It can help prolong system performance

As it grows less efficient, the performance of your air conditioner overall could suffer, with it becoming louder or starting to heat your home unevenly. The more energy it consumes, the sooner its parts might need replacing, and it may need cleaning or servicing more regularly. 

It can minimise the impact on your system

From your air conditioning system to your own system, setting your air conditioner at the wrong temperature can contribute to more sleepless nights, which weaken your immune system, and leave you less able to take on the day. Overly air conditioned homes can also contribute to upper respiratory issues, like runny noses and dry throat.
