What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Rehoboth Beach, DE, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the DE climate.

Preparing for a Blower Door Test in Rehoboth Beach, DE

Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Rehoboth Beach, DE.
