Energy Saving tips when using air conditioners

Here 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 house (or shade the air conditioner itself); make sure the air flow around it isn’t obstructed. with plants, The temperature of a heated room in winter should be between 18-21Âmbient °C while the temperature of a cooled room in summer should be about 23-26Âmbient °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 – 45 minutes.
  • When a hot day is expected, turn on the air conditioner earlier rather than wait till the house 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 type air conditioners require some air flow and are used more in low humidity environments. Close curtains on hot summer days and cold winter nights. Outdoor shading of windows in summer is very effective.
  • If the indoor unit has adjustable louvres, adjust them towards the ceiling when cooling, and towards the floor when heating (as cool air falls, hot air rises).
  • Regular cleaning of air filters as per manufacturer’s recommendations..
