What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Springfield township, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

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. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Springfield township, NJ.
