Quick Tips

Heat Pumps
  • Do not set back the heat pump’s thermostat manually if it causes the electric resistance heating to come on. This type of heating, which is often used as a backup to the heat pump, is more expensive.
  • Clean or change filters once a month or as needed, and maintain the system according to manufacturer’s instructions.
Heating and Cooling Tips:
  • Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer.
  • Clean or replace filters on furnaces once a month or as needed.
  • Clean warm-air registers, baseboard heaters, and radiators as needed; make sure they’re not blocked by furniture, carpeting, or drapes.
  • Bleed trapped air from hot-water radiators once or twice a season;if in doubt about how to perform this task, call a professional.
  • Place heat-resistant radiator reflectors between exterior walls and the radiators.
  • Turn off kitchen, bath, and other exhaust fans within 20 minutes after you are done cooking or bathing; when replacing exhaust fans, consider installing high-efficiency, low-noise models.
  • During the heating season, keep the draperies and shades on your south facing windows open during the day to allow the sunlight to enter your home and closed at night to reduce the chill you may feel from cold windows.
  • During the cooling season, keep the window coverings closed during the day to prevent solar gain.
Air Duct Tips:
  • Check your ducts for air leaks. First, look for sections that should be joined but have separated and then look for obvious holes.
  • If you use tape to seal your ducts, avoid cloth-backed, rubber adhesive duct tape, which tends to fail quickly. Researchers recommend other products to seal ducts: mastic, butyl tape, foil tape, or other heat approved tapes. Look for tape with the Underwriters Laboratories logo.
  • Remember that insulating ducts in the basement will make the basement colder. If both the ducts and the basement walls are uninsulated, consider insulating both. Water pipes and drains in unconditioned spaces could freeze and burst in the space if the heat ducts are fully insulated, because there would be no heat source to prevent the space from freezing in cold weather. However, using an electric heating tape wrap on the pipes can prevent this. Check with a professional contractor.
