Finding Air Leaks
Locating air leaks can be tricky. They're often so small as to be hardly noticeable. To find them, follow a trail of smoke.
Close all the windows in the house, turn off all the fans and exhaust fans, and shut off the furnace. Light some incense and walk slowly around the outer walls of the house. Anywhere you notice the smoke blowing away from something or being sucked toward something, there's probably an air leak. Now that you've found it, seal it! Here's how.
