Energy rating labeling on air conditioners has taken a big leap forward, with the new Zoned Energy Rating Label (ZERL), mandatory on new reverse cycle split system models from April 1, 2020. The new label allows consumers to make a more informed decision for their heating and cooling; including how much heating and cooling power a model has, energy efficiency based on location, electricity usage and noise production.
How do I read the new ZERL label?
Use the handy graphic below to understand what each section of the new ZERL label means.
How can I compare different models?
You can compare the efficiency of different units using the star rating, but:
- you must compare products of the same or similar size
- due to the different methods of calculating the star ratings you shouldn’t compare the star rating on the old label versus Zoned Energy Rating Labels.
For a fair comparison of energy usage, ensure the models you are comparing are of similar capacity. These numbers can be found at the top of the ZERL label:
Size matters.
A correctly sized unit will make heating and cooling more efficient, affordable and comfortable.
Factors to consider include:
- Whether you are looking to heat/cool a single room, a larger space or your entire home
- Size of room/home (including ceiling height)
- External wall materials
- Insulation levels
- How many windows you have, their glazing, shading and orientation
