What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Bordentown township, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

Homes throughout Bordentown township, 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 Bordentown township, NJ

To ensure accuracy during blower door test in Bordentown township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Bordentown township, NJ.
