CHOICE Expert Rating
View more details.
This overall score is made up of cooling efficiency (40%), heating efficiency (40%) and airflow (20%).
-
Cooling efficiency score
View more details.
Cooling efficiency scores are based on the model's AEER (Annual Energy Efficiency Ratio) – a measure of efficiency that factors in standby power consumption when the unit's not in use. Our scores are more precise than star ratings.
-
Heating efficiency score
View more details.
Heating efficiency scores are based on the model's ACOP (Annual Coefficient of Performance) – a measure of efficiency that factors in standby power consumption when the unit's not in use. Our scores are more precise than star ratings. "NA" (not applicable) means this is a cooling-only model.
-
Airflow score
View more details.
Based on the range of airflow on the lowest to highest fan speed settings. Ideally, air conditioners should have a gentle airflow on low settings and a powerful airflow on high. The wider the range of airflows, the better the score.
-
Brand reliability score
View more details.
Brand reliability is based on our 2020 member survey and shows the percentage of respondents owning that brand of air conditioner who reported no problems with it in the previous 12 months. "Not available" means we didn't get enough responses to score that particular brand.
-
Owner satisfaction score
View more details.
Owner satisfaction is based on our 2020 member survey and shows how satisfied respondents who own that brand of air conditioner are with their purchase.
-
Price

-
Yearly running cost
View more details.
An estimate of how much each model will cost to run, based on a set amount of cooling and heating (for reverse-cycle models) or just cooling (for cooling-only models) per year, including standby power (based on an electricity cost of 30 cents/kWh). Your actual running costs will vary depending on how much you use the air conditioner, how well-insulated your home is, and more.
-
Size (capacity)
View more details.
Small (up to 4kW cooling capacity) models are good for a bedroom or study. Medium (4 to 6kW) models are good for a large bedroom or living room. Large (over 6kW) models are good for large, open-plan living areas.
- Small

Zoned star rating cooling – cold zone
View more details.
The zoned energy label shows cooling star ratings for different zones: the cold zone covers southern Australia including Melbourne, southern WA, Canberra and eastern state mountain regions, and Tasmania. It also includes New Zealand. The more stars, the better the air conditioner is for cooling in these regions. This rating is not available ("N/A") for some older models that are still on the market but not registered with the new label.

Zoned star rating cooling – average zone
View more details.
The zoned energy label shows cooling star ratings for different zones: the average zone covers the middle zone of Australia including Sydney, Adelaide and Perth. The more stars, the better the air conditioner is for cooling in these regions. This rating is not available ("N/A") for some older models that are still on the market but not registered with the new label.

Zoned star rating cooling – hot zone
View more details.
The zoned energy label shows cooling star ratings for different zones: the hot zone covers northern Australia including Darwin and Brisbane. The more stars, the better the air conditioner is for cooling in these regions. This rating is not available ("N/A") for some older models that are still on the market but not registered with the new label.

Sleep mode adjusts the air conditioner's output temperature and fan speed (usually in steps) so the temperature becomes more comfortable for sleeping and the air conditioner runs at lower power and more quietly.
- Yes
-
Sleep mode auto temperature adjustment
View more details.
"Yes" indicates that the model's sleep mode adjusts the air conditioner's output temperature in steps, so the change is gradual.
- Yes
-
Human presence sensor (energy saving)
View more details.
This feature detects whether anyone's in the room; if no one's there, the air conditioner switches to an economy mode to reduce power consumption. Some models also direct the air movement towards the sensed person, so as to not cool or heat unused areas.
- Yes
-
Wi-fi control
View more details.
Allows control of the air conditioner via your home wireless network and an app on your smartphone, so you can power the unit on or off when away from home, set temperatures and monitor energy use. It's not available for all models, but is built-in for some and an optional extra for others.
