Air leaks in your home can waste energy and make your home less comfortable. Checking for and sealing air leaks is a relatively simple and inexpensive way to improve the energy efficiency of your home.
There are a few different ways to check for air leaks in your home. One way is to use a smoke pencil. Light the smoke pencil and hold it near potential leak areas, such as around windows, doors, and pipes. If the smoke is drawn into the leak, you’ll know that there’s a leak there.
