What Temperature Should I Set My Air Conditioner in Summer?

The arguments about office thermostats and the return of short sleeves are clear signs that summer has officially returned. But did you realise that a whooping 20 to 50% of your energy cost goes towards heating and cooling your home?

The expense of running your air conditioner throughout the summer can be significantly reduced by setting it to the ideal temperature. We’re here to explain in detail the appropriate temperature for an air conditioner as well as what you can do to achieve maximum energy efficiency without working up a sweat.

What’s the Best AC Temperature for Summer?

The ideal range for your air conditioner in the summer is typically 25–27°C. There are certain restrictions, though, such the fact that this presupposes you are in a region with a moderate climate. We’ll break down the ideal temperature for air conditioning by location because we know many of you wouldn’t consider Australian summers to be “moderate.”

How Temperature Setting Affects Running Costs

Your air conditioner will have to work harder and use more energy the lower the temperature is set to in the summer. Energy usage increases energy costs. The energy utilisation of your air conditioner increases by about 10% for every degree you lower the temperature. Although it might not seem like much, over time, it adds up on your energy cost.

Based on the cooling capacity, temperature setting, and usage, you may use the Ergon Air Conditioning Calculator to estimate your system’s running expenses. For instance, it will cost you $191.75 to run a 6.0kW air conditioner at 21°C for six hours every day for a period of 12 weeks. However, lowering it to 25 °C might save you $56.16.

Fortunately, there are additional steps you can take to save your energy costs and ensure that your air conditioner operates at its best.

Ways you can save Money on Your Air Conditioning unit

While an increase in your energy costs is inevitable when using air conditioning, you may reduce how much it rises. Beyond just changing the temperature, there are six simple things you can do to ensure that your air conditioner uses less energy.
