Energy-Saving Tips

  • Install a programmable thermostat to control energy costs while you are away or sleeping.
  • Check the furnace filter monthly and replace or clean it as needed. Old or dirty filters cause your system to work harder, resulting in energy waste and possible system damage.
  • A humidifier can help control heating costs because moist air will feel warmer.
  • Adjust register openings in the home. Remember that heat rises so registers should be partially closed upstairs. They should also be free of obstructions such as furniture, lint, dust or pet hair.
  • Use draperies, blinds, curtains or shutters to slow the loss of heat through the glass.
  • Rearrange furniture, placing it next to inside walls and away from windows. Avoid blocking registers.
  • Use kitchen, bath or other ventilation sparingly.
  • Make sure mountings on ceiling fans are snug and tight.
  • Purchase inexpensive gaskets to seal cold air entering through electrical switches and outlet plates.
  • Closets and cabinets can leak cold air. Make sure they are tightly closed.
  • Trim bush and shrubbery near outdoor air conditioner or heat pump. Remove debris that may have collected around the unit.
  • Clean the outdoor coil on the air conditioner or heat pump. Use a garden hose to gently run water over the coil.
  • Make sure the unit remains level. Ground shifting or settling can cause an air conditioner or heat pump to sit in an uneven position.
