Keep the sun out. Close blinds, shades and drapes on the sunny side of your home during the day to keep the house cooler.
Adjust your thermostat. When at home, set it a few degrees higher to save energy. When you are away, adjust your thermostat 7 to 10 degrees higher than your normal setting for at least 8 hours a day. This can help you save 10% on your energy bill.
Manage your energy costs with Budget Billing. Budget Billing spreads your annual charges more evenly over 12 months.
Turn down the heat by delaying heat-producing activities such as cooking, drying and ironing until evenings or when the weather cools.
Leave thermostat’s fan switch on “auto” so the fan only runs when the furnace runs. Setting the fan to “on” causes it to run all the time.
Seal cracks and gaps around windows, doors and siding with caulk and weather stripping. This keeps cool air in and hot air out.
Use standing fans, even if you have air conditioning. Circulating cool air makes it feel cooler.
Install a programmable thermostat for your comfort and convenience. It can adjust the air conditioning for times you typically are away and times you typically are home. You also can program it to reduce cooling when you go to sleep and turn it back up before you wake up in the morning.
Schedule regular tune-ups for your air conditioner. Seasonal maintenance keeps equipment running safely and efficiently, and saves money in the long run.
