Blower Door Test in Lahaska, PA

How Is A Blower Door Test Conducted?

To conduct blower door test in Lahaska, PA, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.
