Blower Door Test

Controlling air infiltration in your home is a critical step to home energy efficiency.

Penetrations in the building envelope or holes and gaps and a pressure difference, creates a great deal of air infiltration.

To find out the problems in this area, we perform what is called  Blower Door Test.

Simply explained, a powerful blower fan is placed in an exterior door as in the image above.

When it is turned on, the fan blows air out of the home, thereby the pressure inside the home is lower than that of the outside of the home.

Outside air then comes in through any cracks and holes in the exterior of the home.

Our certified technician will use a 'smoke pencil' to help detect any air leaks.
