Large air conditioner reviews

Last tested: 04 September 2015

We compare 50 reverse-cycle split-system inverter air conditioners, priced from about $1300 to over $5000. This comprehensive report includes air conditioners with cooling capacities from 6.1kW to 9.4kW, suitable for single rooms to large open-plan living areas.

See our buying guide so you know what features to look for, and read about how we test air conditioners.

We'll tell you:

  • what to buy
  • which models cool and/or heat the best
  • which models have the best airflow

Our interactive comparison tool helps you see at a glance good and bad points for each model, including cooling and heating efficiency, running costs over a year, noise levels, and more. Our CHOICE Buys will help you see quickly which models come out on top.

Costs

Yearly running cost
Expand to view more details.

Calculated based on how much each model costs to deliver 3000kWh of full cooling and 3000kWh of heating per year when running at its measured maximum capacity, with the remainder of the year in standby mode (based on electricity costs of 28 cents/kWh). Standby costs add only a few dollars a year, but it may still be a good idea to unplug your air conditioner (if possible) when it's not in use for long periods. While we've based our calculation on a reasonably typical usage, the annual running costs are only an indicative comparison. Your mileage will vary depending on your house, local climate, electricity price and how much you use the air conditioner.

Test results

Cooling efficiency score
Expand to view more details.

Cooling and heating efficiency scores are based on the model's AEER (Annual Energy Efficiency Ratio) and ACOP (Annual Coefficient of Performance), which is a measure of operational efficiency that factors in standby power consumption when the unit is not in use. For this reason, we don't directly score the standby power consumption, but it is listed for your information.

Features

Human presence sensor (energy saving)
Expand to view more details.

This feature detects whether anyone is in the room so that the unit knows to keep cooling (or heating) the room. Some models also direct the air movement towards the sensed person, to focus on that area of the room and not unnecessarily use energy to cool other sections. If no-one is detected, the unit reduces its cooling or heating output and therefore its energy consumption (usually without switching off altogether).

Sleep mode
Expand to view more details.

Sleep mode adjusts the air conditioner's output temperature and fan speed (usually in steps) so the temperature becomes more comfortable for sleeping and the air conditioner runs at lower power and more quietly.

Demand Response feature (DRED)
Expand to view more details.

Demand Response Enabling Device (DRED), also known as PeakSmart. An air conditioner with this feature can be controlled remotely by participating energy companies in periods of peak electricity demand, to be turned off intermittently or run in power-saving bursts. This alleviates pressure on the power network, and owners may receive a rebate or one-off cash payment.
