Air sealing is an inexpensive way to lower energy costs and improve comfort. Proper insulation is important to keep your home cool in the summer and warm in the winter.
- Seal from the inside. Seal gaps and holes in walls, floors, and ceilings with caulk or foam sealant. Look for cracks around windows and where wires and pipes pass through.
- Caulk along baseboards with a clear sealant.
- Caulk around openings where water and drain lines through walls underneath bathroom and kitchen sinks.
- Caulk electrical wire openings at the top of the interior walls in the attic.
- Ensure windows and doors are properly weather-stripped and use door sweeps.
- Ensure window A/C unites are weather-stripped.
- Caulk around storm windows and basement windows.
Air Ducts and Insulation
- Have your duct work checked for leaks. Leaks at the return, air handler and supply can be a major source of high bills. For mobile homes, check for leaks at the grill, cross over duct and down flow air handler.
- Ensure attic access door closes tightly and is insulated.
- Make sure insulation in your attic does not block soffit vents.
- Verify your ducts are tightly connected to your HVAC equipment. Well-sealed and insulated ducts can save up to 10%.
- Insulate electric wall outlets and wall switches with foam pads.
