Use this audit to evaluate your home. After you have completed it, take it to the hardware store or home center for the tools, materials, and advice on how to plug the leaks that are costing you money in higher heating and cooling bills.
Begin by checking the exterior doors for these possible leaks:
•Cracks where the door meets the frame.
•The joint between the frame and the exterior and interior walls of the house
•The bottom of the door at the threshold.
•Between the base of the threshold and the floor underneath.
•If your door has windows, are they properly glazed or is the glazing old and cracked or missing entirely.
•If the doors have existing weather-stripping, is it still in good shape or does it need replacement.
Look at your windows next:
•How many windows have moving parts that allow leaks?
•Are there any gaps or flaws in construction around the frame?
•Are seams around the window trim caulked?
•If weather-stripping exists, is it adequate or in need of replacement.
•Are storm windows installed and properly fitted and caulked to eliminate gaps where the window meets the framing
Once you have covered all the conventional openings, look for the not-so-obvious ones
•Foundation cracks or crack in basement walls
•Separation between any two materials of the house construction like an exterior chimney and the house
•OPhone, electrical, or cable lines
•Clothes dryer vent
•Outside light connections
•Cracks or splits in the siding
•Gaps or loose mortar between blocks, bricks, or stone facing
•Air ducts for heating and cooling system
•Improper insulation around window air conditioning units
•Leaky basement windows
•Gaps around roof flashing
•Split or loose shingles
•Poor drainage around house
•Damaged, blocked, or poorly connected downspouts
•Gaps around garage door
Energy also leaks from your home by other opening.
•Is your furnace properly cleaned and tuned for maximum efficiency?
•Is the air filter clean?
•Check the range filter
•Check for dirty or blocked heating/cooling registers
•Do you set your thermostat too high in winter and too low in summer?
•Do you have a programmable thermostat and do you use it?
•An improperly located thermostat (too near to a heat or cool source or an outside wall) can waste energy
•Check for leaks in heating and cooling ducts and joints
•Is your hot water heater set at an efficient temperature?
