Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Mantua, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Houses in Mantua, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Mantua, NJ helps optimize energy use and ensures you meet local building standards.

Preparing for a Blower Door Test in Mantua, NJ

When preparing for blower door test in Mantua, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Mantua, NJ energy efficiency codes.
