At home


Heating and cooling for your home - without sacrificing your comfort or costing a fortune - can be done efficiently by installing a reverse cycle air-conditioner.

Compare air-conditioner star-ratings

Compare energy star ratings
  • Use the energy rating labels to find the most efficient system for your needs. The star rating for cooling is shown in a blue semi-circle; heating in a red crescent.
  • The more stars, the less money you lose on running costs.
  • Compare models with the same star-ratings and capacity output using the energy consumption specification in the middle of the label.
  • The lower the energy consumption score, the less money you spend on running costs.

Cut your air-conditioner running costs by 10 per cent with every extra energy-rating star.

Calculate the air-conditioner running costs

Running costs can exceed the purchase price of some electrical appliances, so use the Energy Rating Calculator to calculate the energy efficiency of air-conditioners before you buy.

The Energy Rating Label, displayed on all new electrical appliances, can help you compare the long-term value offered by different appliances running costs:

  • Every extra star on the Energy Rating Label can save around 10 per cent on the running costs of an air-conditioner.
  • You could save a further 10 to 20 per cent by setting the thermostat between 23°C and 26°C when in cooling mode. When in heating mode, set your thermostat at 18°C to 21°C.
  • Gas heaters and reverse-cycle air-conditioners produce around one-third of the emissions of electric heaters.
  • Fans are much cheaper to run than air-conditioners.
  • Air-conditioners come in both cooling only and reverse cycle models, which provide both heating and cooling.
  • Seek professional advice to make sure you get an air-conditioner with the right output capacity for the room you will be cooling.
  • Look for an inverter model, as they’re quieter to run and give additional energy savings.
  • Consider replacing an air-conditioner that is more than 10 years old with a newer more efficient model. Older units can be costly to maintain and use more electricity.
