Air conditioning energy efficiency requirements

Air conditioning is widely used in South Australia to help maintain a comfortable environment for living and working.

Improving the efficiency and managing the energy use of residential air conditioners helps to:

  • reduce the running costs of air conditioners
  • better manage the growth in South Australia's peak electricity demand
  • reduce greenhouse gas emissions caused by air conditioner use.

Energy efficiency requirements for residential-size air conditioners

Certain types of air conditioners must meet national Minimum Energy Performance Standards (MEPS) before they can be sold in Australia. They include split systems, window wall units, and ducted refrigerated air conditioners up to 65 kilowatts (kW) in capacity. It is illegal to sell these types of air conditioners in South Australia if they don’t meet the national MEPS.

MEPS don't apply to evaporative or portable air conditioners.

MEPS reduce the amount of energy consumed by air conditioners. A highly efficient air conditioner requires less electricity to cool an area, which is particularly beneficial on hot days, where air conditioner use is strongly linked to the high demand for electricity.

MEPS can also be applied to equipment that affects the energy efficiency of appliances, such as ductwork.

For more information about the MEPS requirements see the Energy Rating website.

See cooling and heating for more information about using and buying air conditioners.
