1. Make sure your window A/C unit is installed properly. Air leaks can cause excessive energy use.
  2. Make sure all windows and storm windows are closed and latched when using air conditioning. Do not use bath and kitchen fans unnecessarily.
  3. Keep room temperature 70 degrees or above. Air conditioning feels good mostly because the humidity has been removed from the air. Usually 72 degrees will feel comfortable once you have been in the air-conditioned room for 10-15 minutes.
  4. Close door quickly behind you when entering and leaving your dwelling. Allowing the door to remain open for even short periods will allow outside humid air to enter your dwelling. It will take considerable time and energy for your A/C unit to catch up. This is especially important on extremely hot or humid days.
  5. Turn your thermostat up to 75 degrees on central units or set the dial to “low” on window/wall units when you are not going to be at home. ┬áThis will still keep the humidity level low and it will not take long to get the temperature back down to 70-72 degrees once you return home.
  6. Use fans to move air from the cooler rooms to warmer areas in your dwelling.
  7. Keep the blinds closed on the sunny side of the house, especially when you are not at home. This will keep your home cooler and will help reduce the cost running your A/C.
