Most Energy Efficient SPLIT Air Conditioners
Tables 1,2,3 below compare the most energy efficient split air conditioners available in the Australian market as at Feb 2019. Out of the large stock of air conditioners available, we have only chosen to list the top performing models to assist with your next energy efficient split air conditioner purchase. Whilst we are biased towards energy efficiency, there are other factors to consider in choosing the best-fit air conditioner, namely reliability, functionality, size, noise, aesthetics, operating features, budget, etc
If wall space is a not available to mount your energy efficient split air conditioner, we have also compiled a list of the most energy efficient CASSETTE TYPE air conditioners for your information(Cassette type air conditioners are recessed into the ceiling). In addition – we list compare the energy efficiency of MULTI type air conditioner systems.
SCROLL DOWN – The tables below are quite wide and best viewed using a large computer screen.
Table Notes:
- All Air conditioners listed below are ‘non-ducted’, ‘wall hung’ & ‘single-split’ type.
- ‘Heat COP‘ = the Coefficient of Performance in heating mode (the higher the number the more energy efficient)
- ‘Cool EER‘ = the Energy Efficiency Ratio in cooling mode (the higher the number the more energy efficient)
- ‘Heat Stars‘ = no: of ‘Energy Rating Stars’
issued by the Australian GEMS Regulator for Heating mode Energy Efficiency. - ‘Cool Stars‘ = no: of ‘Energy Rating Stars’
issued by the Australian GEMS Regulator for Cooling mode Energy Efficiency. - ‘Heat Out‘ = Heating mode Output capacity in kilowatts(kW)
- ‘Cool Out‘ = Cooling mode Output capacity in kilowatts(kW)
- ‘Heat Input‘ = electricity input in kilowatts(kW) required for Heating mode operation
- ‘Cool input‘ = electricity input in kilowatts(kW) required for Cooling mode operation
- Air Conditioner models & types have been sourced from the Australian government online database listing registered products under the Greenhouse and Energy Minimum Standards Act 2012. Split air Conditioner models have been selected & ranked based upon their performance for listed efficiency variables: – ‘EERtestAvg’ and ‘COPtestAvg’
- Green Wire Consulting provide unbiased advice & receive no commissions from any product suppliers. Only air conditioners with superior technical energy efficiency performance are listed on this page.
- Prices shown are estimated purchase costs only, further research is required to obtain current costs. Installation costs are additional.
- Confused about the table? As part of our consulting services, we can explain how to select the most energy efficient split air conditioner that will suit your application – as part of our home energy audit or business energy audit. If required we are also able to test and measure the energy efficiency performance of your existing split air conditioner.
