What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Midland Park, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Midland Park, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction.

Preparing for a Blower Door Test in Midland Park, NJ

To prepare a home for blower door test in Midland Park, NJ, we shut off the HVAC system and disable all exhaust fans. 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 the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Midland Park, NJ.
