What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Fort Lee, 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 is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

Houses in Fort Lee, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Preparing for a Blower Door Test in Fort Lee, NJ

As part of preparing for blower door test in Fort Lee, NJ, we power down the HVAC system along with kitchen and bathroom 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 all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Fort Lee, NJ energy code requirements.
