Air Leaks are More Than Drafts
- You can save 10% or more on your energy bill by reducing air leaks in your home.
- Look for light under exterior doors. These are clear signs of leaks.
- Feel for air movement around windows and doors on a cold or windy day. If you can feel air moving, it's a leak.
- Fireplaces, operating or not, can be a major source of leaks.
