What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Skippack, PA is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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 exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

Preparing for a Blower Door Test in Skippack, PA

When preparing for blower door test in Skippack, PA, we first switch off the home’s heating, cooling, and exhaust systems. 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. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Skippack, PA energy standards.
