Reducing Power Bills (Cooling model)
A key to reducing air conditioning costs is to limit the amount of heat generated within the home or apartment.

• Keep lights off when rooms are not in use. Lights generate heat that makes your air conditioner run more.
  
  
• Use awnings, curtains, or blinds to keep out direct sunlight. This will keep your house cooler.
  
  
• Eliminate activities in the afternoon that require a great deal of in and out through the doors of your home. This allows cool air to escape and hot air to enter the home.

More Efficient Air Conditioning
One of the most inexpensive and effective ways to reduce your air conditioning costs is to adjust your thermostat setting.

• The savings can be significant when you set your thermostat at 1°C or higher (Cooling model) / 2°C or lower (Heating model). For each degree you raise your thermostat setting, you reduce seasonal cooling costs by 10%.
  
  
• Use a ceiling fan or portable fan to supplement your air conditioning. A fan can make you feel a few degrees cooler so you can set your thermostat a few degrees higher and save on cooling costs.
  
  
• Be sure your air conditioner is not blocked. A free flowing air conditioner operates most efficiently. Filters should be checked every 2 weeks. Dirty filters may reduce cooling and heating efficiency.
  
  
• When air conditioning is on, keep doors and windows closed. Turn off kitchen or bathroom exhaust fans when your air conditioning is operating.
  
  
• Caulk and weather-strip leaky windows and doors.
  
  
• Shade your home from direct sunlight. Use shades, drapes and awnings to block the hot sun from heating up your home
  
  
• If you suspect your air conditioning system is not cooling/heating properly, have it checked promptly. A unit that is having operational problems can cause extremely high bills.
  
  
• If your air conditioning equipment is older and less efficient, compensate by being extra careful about temperature settings, hours of operation and filter condition.
