Hints and Tips

Air conditioning general maintenance and operation tips

Here are some energy saving tips to get the most out of your air conditioner:

  • Shut windows and external doors when operating the air conditioning
  • Minimise the area being cooled or heated by shutting doors to unused rooms
  • Regularly clean filters
  • Locate the external section of the air conditioner (compressor) away from direct sunlight, and with good air flow around it
  • Set the thermostat between 23 and 25 degrees C for optimum operation
  • Reduce the amount of heat entering the building by shading windows and walls, insulating ceilings and walls and sealing draughts
  • Open up windows and external doors if the outside temperature is lower than the inside temperature, instead of using the air conditioner.

When selecting an air conditioner, look for:

  • 7 day programmable timer and thermostat controls. Set your air conditioner at the highest temperature setting at which you still feel cool enough - 25 degree C is usually adequate. Each 1 degree C increase of the thermostat setting will save about 10% on your energy usage.
  • Movement sensors, which reduce power and energy usage when the room is unoccupied.
  • 'Set-back' and 'sleep' modes that automatically adjust thermostat settings.
  • Economy settings
  • Multi-speed fans
  • Adjustable and rotating louvres
  • Remote thermostats and controls


Saving Energy when using air conditioners

There are some simple things you can do to save energy when using an air conditioner:

  • Install the air conditioner (or outdoor unit of a split system) on the shady side of the building (or shade the air conditioner itself); make sure the air flow around it isn't obstructed.
  • The temperature of a heated room in winter should be between 21-23 degree C while the temperature of a cooled room in summer should be about 23-25 degree C (remember the humidity indoors will be low, so it will feel cooler). The temperature should be checked after the air conditioner has been operating for 30 minutes.
  • When a hot day is expected, turn on the air conditioner early rather than wait till the building becomes hot (it operates more efficiently when the outside air temperature is cooler).
  • Keep windows and doors closed when using a refrigerative air conditioners (evaporative air conditioners require some air flow). Close curtains on hot summer days and cold winter nights. Outdoor shading of windows in summer is most effective.
  • If the machine has adjustable louvres, adjust them towards the ceiling when cooling, and towards the floor when heating (as cool air falls, hot air rises).
  • Follow the manufacturer's instructions for filter cleaning.
