Zoned Energy Rating Label for air conditioners

Many air conditioners for sale in Australia and New Zealand now display a Zoned Energy Rating Label (ZERL). The ZERL provides a seasonal efficiency rating for 3 distinct climate zones — hot, average, and cold. The label displays performance information to help consumers select a product that is suitable for their climate zone. Ratings are up to a maximum of 10 stars for both heating and cooling.

The capacity output figures on an air conditioner label will let you know the amount of cooling and heating the model can produce.  Also included in the new labeling is a noise indicator, to show the volume in decibels of the internal and external units.

Labels on ducted systems are voluntary, so not all products will have one.  

See Energy Rating for more information on the ZERL.
