What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Millburn, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Millburn, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Millburn, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this level during your blower door test in Millburn, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Millburn, NJ

To get ready for blower door test in Millburn, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces 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 depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Millburn, NJ efficiency codes.
