Air leaks in your home increase the load on your HVAC system, resulting in higher energy costs and inefficient heating and cooling. With very little time and money, you can seal air leaks and save money on your heating and cooling bills while staying more comfortable year round. Follow these steps to seal the most common sources of air leaks in your home.
1. Doors and windows
- Apply caulk to cracks and gaps between stationary components of doors and windows, and install weatherstripping between movable parts.
- Replace old windows with energy-efficient models. If doing so is cost-prohibitive, inexpensive window insulation kits are very effective at keeping out drafts.
2. Walls and floors
- Install pre-cut foam gaskets behind outlet and light switch covers on exterior walls.
- Apply caulk around pipes and vents that penetrate exterior walls.
- Insulate your attic. Fiberglass insulation should be at least 11 inches thick and loose fill should be at least 8 inches deep.
- Inspect your ducts for loose joints and cracks, and seal them with metal tape or mastic.
- Insulate your ducts as far as you can reach, especially those in unconditioned areas of your home.
- Have your chimney cleaned and inspected annually for cracks by a professional chimney sweep.
- Keep your damper closed when your fireplace is not in use.
5. Fans and vents
- Apply caulk around fans and vents that penetrate exterior walls, such as your dryer vent and bathroom fans.
6. Plumbing penetrations
- Apply expanding caulk around gaps where your plumbing pipes penetrate exterior walls and floors.
