What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Macungie, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

Preparing for a Blower Door Test in Macungie, PA

Before conducting blower door test in Macungie, PA, we make sure all heating, cooling, and ventilation fans are switched off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Macungie, PA efficiency codes.
