Fujitsu air conditioners for sale in Australia and New Zealand are transitioning to displaying the NEW Zoned Energy Rating Label (ZERL). The new label provides a seasonal efficiency rating for three distinct climate zones across Australia and New Zealand - HOT, AVERAGE, and COLD. The star rating on the old label measured how much cooling or heating output was achieved per unit of power. It related to the efficiency of the air conditioner at a particular temperature but did not take into account consumer usage patterns in different locations of Australia to determine typical electricity use. The star ratings on the new label reflect how the air conditioner will perform over a range of temperatures and allows an annual electricity figure to be calculated. For more information, please talk to your salesperson to make sure you get the most efficient model to suit your requirements.
