What Is The Most Efficient Temperature For Air Conditioning in Australia?

The most efficient temperature for air conditioning ultimately depends on the season and the climate of where you live. For example, the best temperature for air conditioning in summer in Australia will vary depending on what region you live in. Despite our extremely diverse climates, most Australians set their air conditioners to 22 degrees in summer and 19 degrees in winter without accounting for the local climate.

Below, we explore the best air conditioning temperature for you, depending on where you live in Australia.

This region has a sub-tropical climate.


For the ideal air conditioning temperature, set your thermostat to 25 degrees Celsius in summer. If you change your temperature from 22 degrees to 25 degrees, you will cut your daily air conditioning energy consumption by more than 20 per cent.


In Southeast Queensland and northern New South Wales winter, set your air conditioner to a balmy 18 degrees Celsius.

North Queensland, North Western Australia, Northern Territory and Central Australia

These regions have a tropical climate.


The most efficient air conditioner temperature is 21-23 degrees Celsius in summer.


Set your winter heating to 17 degrees Celsius in winter.

South Australia

This region has a Mediterranean climate.


The recommended air conditioner temperature for Australians in this region is 24 to 25 degrees Celsius in summer.


Set your air conditioner’s reverse cycle heating to a pleasant 19 to 20 degrees Celsius in winter.


This region has a mild temperate climate.


In summer, the best temp for aircon in Tasmania is 28 degrees Celsius.


In Tasmanian winter, air conditioners perform best and most economically at 21 degrees Celsius.

Southwestern Western Australia

This region has a Mediterranean climate.


In southwestern Western Australia, air conditioners work best when set between 23 and 24 degrees Celsius.


In winter, the best temperature for reverse cycle heating is 18 degrees Celsius.

Southeast New South Wales, Northeast Victoria and Australian Capital Territory

This region has an oceanic climate.


Throughout this region, the best temperature for air conditioners during summer is between 26 and 27 degrees Celsius.


For a cosy winter, the ideal AC temperature is 20 degrees Celsius.

Southern Victoria

This region has a moderate oceanic climate.


For best results in summer, set your AC temp to 24 degrees Celsius.


To keep your home toasty in winter, we recommend an ideal aircon temp of 20 degrees Celsius.

Why Do The Recommended Temperatures Vary Between Regions?


Air conditioners have to work harder to offset harsher climates. This means people living in warmer climates should set their cooling temperature a little lower, while people in cooler climates should set their heating temperature a little warmer.

What Is The Most Economical Way To Run An Air Conditioner?


On the hunt for the most economical way to run an air conditioner? The best long-term method is to avoid putting excess strain on it. Essentially, the harder your air conditioner has to work to cool or heat a room, the more electricity it will consume.

Setting your air conditioner to the recommended air con temp for your climate will not only help reduce greenhouse emissions, but it will also ensure you still enjoy a comfortable temperature while cutting your electricity bill.

How To Use AC With Less Power Consumption


The question of how to reduce electricity consumption of your air conditioner can be tricky. Here are some useful air conditioning tips to save energy, no matter the season or where you live.

Tip #1: Choose An Energy Efficient Air Conditioner

Typically, air conditioners have a label with a blue and a red star rating. The blue star rating shows its energy efficiency when cooling, and the red star rating demonstrates its heating efficiency. Choosing an energy efficient air conditioner is a smart strategy that will help you save lots of money in the long run.

Tip #2: Invest in Proper Sealing and Insulation

If the home or building you are attempting to heat or cool has poor sealing or insulation, your air conditioner will need to work harder to reach the temperature you have set. This can lead to higher electricity bills. To make sure you’re getting the most out of your air conditioner’s performance, we recommend making sure your home’s sealing and insulation is up to scratch. This will ultimately help increase the lifespan of your air conditioner and keep your electricity bills under control.
