How to Compare Air Conditioner Energy Efficiency?
Comparing air conditioner energy efficiency isn’t just about choosing the highest star rating. To get an accurate comparison, it’s important to look at how a system performs in Australian conditions and how it suits your home.
The best way to do this is by using the Zoned Energy Rating Label, which shows how efficiently a system performs across different climate zones. For Perth homes, focus on the ‘Average’ climate rating, as this reflects typical local conditions. You can learn more about how this works in our guide to aircon energy efficiency or on the official Australian Government page explaining the Zoned Energy Rating Label.
When comparing systems, make sure you are looking at:
- Systems of the same type (e.g. split vs split, ducted vs ducted)
- Similar cooling capacity (kW)
- Star ratings for cooling (and heating if needed)
- Annual energy use (kWh per year), which indicates running costs
For a more accurate estimate of what a system will cost to run in your home, you can also use the official Energy Rating Calculator. This allows you to compare different models based on your usage and electricity rates.

Factors to Consider When Choosing an Energy Efficient Air Conditioner
Choosing the right air conditioner isn’t just about the system itself. Factors like insulation, windows and sunlight, air leakage, and your home’s layout can all impact performance, energy efficiency and running costs. To help you compare your options, here are the key factors to consider when choosing the right system.
Choosing the right size system is essential. An undersized unit will struggle to cool your space, while an oversized system can waste energy and increase running costs.
Split systems are ideal for single rooms, ducted systems suit whole-home comfort, and evaporative cooling works best in Perth’s dry climate.
Look for systems with higher star ratings and lower annual energy use. The Zoned Energy Rating Label is the best way to compare efficiency between models.
Proper installation plays a major role in efficiency. Factors like placement, insulation and zoning (for ducted systems) can significantly impact performance.
