• Change your furnace filter and have your furnace inspected to ensure it is operating efficiently.
  • Move furniture or any obstructions from vents and registers on the floor so that air moves freely.
  • Clean the ducts and area behind the dryer. And don't forget, clean the filter after every use and every once in a while, give it a good wash.
  • Check windows for proper caulking. If you have single-pane windows, add storm windows. Even a plastic film over windows will reduce heat loss.
  • Check doors for weather stripping and replace if needed. Check for drafty areas underneath doors.
  • Check your roof for any missing or damaged tiles or shingles.
  • Check your eaves troughs and make sure downspouts are pointed away from the house.
  • Add foam gaskets behind electrical outlet covers, and use safety plugs in unused outlets.
  • Check for water leaks both inside and outside.
  • Reverse the direction ceiling fans, so the air is being drawn upwards.
  • Have the fireplace chimney cleaned and get vent systems checked.
