One of the easiest ways to reduce high air conditioning bills is to keep your inside window coverings closed on the sunny side of your house. Homes with a large amount of windows, especially on the west side of the house, can save you as much as 28% on cooling costs.
Central air conditioning systems keep you comfortable by removing heat from your home. The better job you do of keeping heat from entering your home the less work your air conditioner has to do.
Heat gain from a window with no inside shading can be as much as 2 1/2 times greater than a properly shaded window. Therefore, keep your inside shades closed whenever possible. If it's practical use outside awnings to shade your windows, this will completely eliminate any heat gain from the sun through your windows.
This simple measure will reduce the runtime of your central conditioner saving your money three ways:
1. Lower utility costs.
2. Reduced A/C maintenance costs.
3. Less air conditioning repairs.
In addition to saving you money and energy, you'll find your home is more comfortable and you will be helping America towards reducing our carbon footprint and energy independence.
