You can save 10% or more on your energy bill by reducing the air leaks in your home.
- Test your home for air leaks. On a windy day, hold a lit incense stick next to the common sources of air leaks shown below. If the smoke travels horizontally, you have found an air leak that may need caulking, sealing, or weatherstripping.
- Pay particular attention to air leaks at doors, windows, and places where plumbing, ducting, or electrical wiring penetrates through exterior walls, floors, ceilings, and soffits over cabinets.
- For a more accurate measurement of air leakage, hire a technician to conduct a blower door test in your home.
