Tips
Set back your thermostat 2-3 degrees lower at night because your greatest heat loss occurs at night.
Invest in a programmable thermostat. By doing so, you can program the thermostat to turn down your air conditioning/heat for you when you leave for work when no one is home and after you go to bed when everyone is asleep. A programmable thermostat can run anywhere from $110 to $250 installed.
Replace your filters every 30 to 60 days. If you have a permanent filter, clean it with a mild detergent, per manufacturer's recommendations, every 30 to 60 days.
In the winter, when it's sunny out, open up the shades to let the sunshine in and heat your home. In the summer, close the shades to keep the warm sunshine out so your air conditioner doesn't have to work as hard.
If your furnace and air conditioning units are over 15 years old, consider replacing them with newer, high efficient units. Doing so can cut your gas and electric bills nearly in half.
