Blower Door Testing


A blower door test is a indicative tool designed to measure air leakage in a home.

 


BlowerDoorEvery home leaks air, but the amount of air leaked depends on how the building was sealed. If your home takes longer to heat up and cool down a blower door test can be conducted to measure the air leakage rate and identify where the leaks are. This tool can be beneficial to both old and new homes.

A blower door test consists of putting a fan mounted into a door frame to lower the air pressure inside a house by pulling air out. A pressure-sensing device is then used to measure the air pressure difference between the inside and outside of the home. A combination of pressure and fan-flow measurements determines the number of air leaks in the home.

 

Minimizing air leaks saves energy and money. The combination of controlling air leaks and upgrading insulation can reduce your energy bills by up to 10% and increase your home’s comfort.
