Room Air Conditioners


Room Air Conditioners

Modern room air conditioners use 50% less electricity than 1990 models. That's a huge savings in your electrical bill this summer, if you replace your old unit. In addition, newer units no longer use Ozone Depleting Substances (CFC or HCFC).

Tips to Save Energy with Room Air Conditioners

Window air conditioners create a large demand on electricity production in the summer time, so the use of fossil fuel and coal generated electricity soars when the temperature rises. Inefficient window air conditioners also contribute to higher emissions of nitrogen oxides into the environment, a key element in producing ground level ozone – commonly referred to as smog.


Tips to Reduce Air Conditioning Use

  • close the blinds or curtains to block out the sun. Turn Up the Air Conditioner
  • to reduce heat gain, consider switching to CFL lights and turning off lights when not in use.
  • using ceiling and space fans.
  • use appliances early in the morning or after sunset.
  • open the windows at night to promote cool air circulation.
  • turn off your air conditioner when you go out and at night.
  • get a yearly tune-up on your room air conditioner by a licensed heating and air conditioning technician.
  • shade your air conditioner. This pre-cooling of the air entering your home means the air conditioner doesn't work as hard. Keep the area clear of weeds and debris.
  • turn the temperature a few degrees warmer.


Contact your local power authority to see if they provide assistance to replace your old air conditioner. In Ontario for example, they provide a $25 rebate for replacing your old unit during 3 weekends in June. They also provide free recycling of old air conditioners to reduce the impact on the environment.
