What Temperature to Set My Air Conditioner in Summer Australia?

Fast read

Selecting the right air conditioner temperature is essential for both comfort and cost-efficiency. As climate change brings unpredictable heat waves, managing energy consumption becomes vital.

Lowering the AC temperature increases energy usage, with a 10% rise for every degree below the outside temperature. The ideal summer AC temperature varies across Australia, ranging from 20 to 28 degrees based on regional averages. However, personal comfort is paramount, and daily outdoor temperatures might warrant adjustments.

For instance, on a 30-degree day, setting your AC to 26 degrees consumes the same energy as 22 degrees on a cooler day. Modern air conditioners, especially reverse cycle ducted systems, offer advanced features for easy temperature management, ensuring consistent comfort throughout the home.

What temperature should I set my air conditioner on in Summer Australia?

Summertime in Australia is the greatest time to go to the beach and soak up some heat. However, it may be a sticky, itchy mess at home without sufficient air conditioning. Heatwaves are growing more often because of climate change, making the weather even more unpredictable.

To combat the heat, it is critical to have air conditioning at home. On the other hand, possessing an air conditioner is only one aspect of the task. Choosing the right temperature for air conditioning in the summertime in Australia is a critical issue that is sometimes disregarded.

This is critical so that neither your comfort nor your finances are jeopardised. In the summer, the lower the temperature you set on your air conditioner, the harder it has to work and the more energy it consumes. Increased energy means increased electricity bills. For every degree you lower your air conditioner, you increase its energy usage by roughly 10%. This may not seem like much, but it adds over time to your energy cost.

Fortunately, there are other things you can do to lower your energy bill and get the most out of your air conditioning equipment. This article will guide you on how to use your air conditioner during a hot Summer.

How the temperature affects the cost

The lower you set the temperature of your air conditioner, the harder it has to work. This means the unit will use more energy, leading to higher bills. Generally, every degree below the outside temperature your air conditioner is set at will increase the air conditioner system’s energy use by 10%. For example, if the temperature is 28 degrees and you set your air conditioner at 25 degrees, the system will work 30% harder.

For a more accurate and detailed answer, you can use some air conditioner calculators available online. These calculators can give you an exact dollar figure of how much you spend or save depending on the temperatures at which it is set.

What air conditioner temperature is best for Summer in Australia?

Generally, the best temperature for your home during summer is whatever makes you most comfortable in your home and with your bill. However, some ‘optimal’ temperatures exist in different regions across Australia.

  • In North Queensland, north Western Australia, the Northern Territory and Central Australia, the best temperature is between 20 and 23 degrees.
  • The best temperature for southwest Western Australia is between 22 and 24 degrees.
  • South Victoria homeowners are best off having their air conditioner at 24 degrees.
  • South Australians should try to set their air conditioner temperature at 25 degrees.
  • In northeast NSW and southeast Queensland, the best temperature is 26 degrees.
  • For northeast Victoria, ACT and southeast NSW residents, the most optimal temperature is between 26 and 28 degrees.
  • Tasmania has the highest optimal temperature, 28 degrees.

Please note that these temperatures are averages. If you set your air conditioner to the recommended temperature of your area and are uncomfortable, please adjust it. Each day is different, so if the temperature outside is higher, you can also increase your air conditioner’s temperature without worrying about the extra charge.

For example, on a day that is 30 degrees, having your air conditioner at 26 degrees will use the same amount of energy as having the air conditioner at 22 degrees.
