What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Oaks, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Oaks, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Meeting this requirement during your blower door test in Oaks, PA helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Oaks, PA

Getting ready for blower door test in Oaks, PA involves turning off all heating, cooling, and exhaust ventilation systems. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Oaks, PA.
