Blower door testing essentially helps identify any air leakage in your home. By measuring the air flow of a blower / fan that depressurizes your home to a standard pressure difference, our energy advisor can tell just how much air leakage your home has.
How It Works
We place our blower door fan in your main entry so it can suck your inside air out. This will cause outside air to be drawn in more aggressively through any crack and gap it finds.
Our energy advisor will identify and diagnose any air leakage from each room in your home. With 20 years of experience, we WILL find and seal those nasty air leaks! We will compile an air leakage inventory using a combination of smoke detection and thermal imaging.
Many older homes lose as much as HALF of their heating due to air leaks. Just think… with a blower door test, you can brag to prospective homebuyers or your buddies about how tight your home is.
What happens during a blower door test?

After Calibrating the device, the fan pulls air out of the house , lowering the air pressure inside.
The higher outside pressure then flows in through all unsealed gaps, cracks and openings such as gaps, cracks and or wiring penetrations.

How much does a blower door cost?
How much does a blower door cost?
$150-$450 Depending on the scope of work. Bigger homes that are leaky will fetch more time on site vs a smaller air tight home.
Does a blower door test pressurize or depressurize?
Does a blower door test pressurize or depressurize?
Either method is acceptable. In general, we tend to depressurize buildings as it prevents a jet of air from being blown into the house during the test process. However, under certain conditions, it is necessary to conduct a blower door test by pressurizing the building.
