I just experience my first blower door test. A blower door test is where you seal up a doorway , then blow air through a hole in the seal with a large fan. Somehow it measures the air exchanges per hour of the building being tested. This give you an idea of how tight or loose your home is.
But the real cool part came in when the test guy took a tool that shows infrared of leaks in the building. Pretty cool. Great way to see where your house is leaking so you can go buy a caulk gun and fix the problem!
