Star ratings
Separate ratings for cooling and heating, with more stars meaning more efficient.
Compare like with like, cooling to cooling and heating to heating.
South Coogee sits above Lurline Bay and the coastal walk, with family homes and units looking out to the ocean. When shopping for a new air conditioner, most people end up staring at energy labels and wondering what the stars actually mean.
Updated October 2026
Air conditioning in South Coogee costs less to run when you choose an efficient model and size it correctly. Australian energy rating labels show separate star ratings for cooling and heating, plus estimated yearly energy use, so you can compare models fairly. We explain the label in plain English and recommend a Daikin system that suits your home and climate zone. Alpha & Omega has installed efficient systems since 1989.
The main parts of the Zoned Energy Rating Label used in Australia.
Separate ratings for cooling and heating, with more stars meaning more efficient.
Compare like with like, cooling to cooling and heating to heating.
Estimated performance in hot, average and cold zones.
Sydney is in the average zone, so focus on those figures.
Estimated kilowatt hours per year for each zone.
Lower numbers mean lower running costs for similar capacity.
Sound ratings for indoor and outdoor units.
Useful when bedrooms are close by.
A high star rating only pays off when the system is the right size for the room. An oversized efficient unit can still waste power by cycling on and off.
Close to the ocean, keeping coils clean also matters, as salt build-up slowly reduces efficiency.
Send them through and we will explain the difference in running costs in plain English.
Models chosen for efficiency, sized to suit.
Strong ratings for single rooms.
Splits →Multiple rooms off a single outdoor unit.
Multi-split →Whole-home comfort with zoning.
Ducted →Clean coils for full performance.
Servicing →Replace low-rated units.

One is for cooling and one is for heating, as a model can be more efficient at one than the other.
Sydney falls in the average zone on the Zoned Energy Rating Label, so those figures are the most relevant.
Often, especially if you run the system a lot, but correct sizing matters just as much.
