What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Woxall, PA helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Woxall, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Woxall, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Passing this requirement during a blower door test in Woxall, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Woxall, PA

To ensure accuracy during blower door test in Woxall, PA, we begin by switching off the HVAC system and all exhaust fans in the home. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Woxall, PA.
