What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Closter, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

Homes throughout Closter, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators.

Preparing for a Blower Door Test in Closter, NJ

To prepare a home for blower door test in Closter, NJ, we shut off the HVAC system and disable all exhaust fans. 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. 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Closter, NJ.
