Blower Door testing
Using some diagnostic tools
and interpreting the results can often be counter intuitive.
Using a blower
door is basic, and typically easy to understand.
The home is put into "winter time"
conditions, all windows and exterior doors are shut. A
blower door is installed in one of the exterior doors to the home with hoses
that lead to the exterior.
The fan is set to push air out of the
home. (Depressurize)
As the home has no windows or doors open, the pressure
in the house drops slightly.
Once the home reaches -50 pascals ( A
very small pressure drop) we can measure the air flow through the
fan. That same amount of air is coming into the
home through infiltration.
While the blower door is operating we
would try to locate the worst performing areas in the home as these areas are
causing the highest amount of heat loss.
Surprisingly, if your home feels
drafty or dry, if you experience any problems listed in
our Common issues page, a Blower Door test is highly recommended !
