Energy Efficiency Tips
For Air Conditioners

Try to install your air conditioner in a shaded area. An air conditioner that is exposed to direct sunlight will consume five per cent more energy than one that is shaded.
When you turn it on, do not switch your thermostat to a colder setting than you need. It will not cool the room any faster. As a rule of thumb, your thermostat should be set to 25.5° C (78° F) or higher if comfort permits.
Turn off your air conditioner when you are not home or program the thermostat to turn on just before you get home.
Proper maintenance of your air conditioner can increase its efficiency by about five per cent. You can clean the outside compressor yourself with a hose, removing debris that impedes air flow.
Match the capacity of a window air conditioner to the size of the area to be cooled. Oversize units waste electricity and can't dehumidify properly.

Do not obstruct air movement. Even with air conditioning, fans will make you feel cooler and reduce the amount of time you need to run your air conditioner.
Make sure the coils on your air conditioner are straight and kept clean. If they are clogged or dirty, you can clean them with a vacuum cleaner.
Periodically check that the filter in your air conditioner is clean. Disposable filters should be replaced every one or two months.
Remember to close the vents in rooms not being used to ensure your air conditioner is only cooling the rooms you're using.
Air conditioning can account for up to 50 per cent of your summer electricity bill so try to use it only when necessary to remain comfortable.
