How can I reduce leakage in my home?
Change your furnace filter monthly during the heating season.
Close the damper on your fireplace when not in use.
Install weather stripping around all doors and windows.
Check all windows, doors, light switches and electrical outlets for air leakage. For example, hold a tissue over each to determine if there is a leak. If necessary, upgrade caulking, weather stripping or in the case of switches and outlets, take off the cover only and install specifically designed gaskets.
