Choosing a reliable, energy efficient system

To save money and problems in the future, you’ll want to make sure that you choose a reliable and efficient air conditioner. It is important to bear in mind that as a large part of the upfront cost of split and ducted air conditioning systems is the installation, buying a cheaper, less efficient air conditioner may not make a large difference to the cost of the entire purchase.

  • Choose a reliable brand.
  • Ask friends and family for their recommendations.
  • Download our printable checklist of things to consider when buying an air conditioning system.
  • Read customer reviews and product reviews online (e.g. choice.com.au, toptenreviews.com and productreview.com.au
  • Check the energy efficiency of the system by looking for the star rating label * or by visiting the Energy Rating website (energyrating.gov.au). More stars mean more energy efficiency, less cost in power bills and less damage to our environment.

* Please note that this rating does not tell the whole story:
This is a rating for the efficiency of the system at full load (full power). A refrigerated air conditioner with an inverter (a variable speed motor) spends much of its time working at part load (i.e. not full power) – this is where they are most efficient. A non-inverter model may be more efficient at full load, but not as efficient overall. For inverter units – check the part load energy performance as well. Ask the retailer, check with the manufacturer or search online.

Remember that for a system to be reliable and efficient it also has to be the right size, be correctly installed, well maintained and be used in an efficient way. No matter how good the system is, ignoring the above will not only reduce the system’s cooling and heating capacity, it will also increase your electricity costs and ultimately shorten the life of your system.
