What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Pine Valley, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Pine Valley, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Construction in Pine Valley, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Meeting this requirement during your blower door test in Pine Valley, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.

Preparing for a Blower Door Test in Pine Valley, NJ

We begin blower door test in Pine Valley, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside 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 home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Pine Valley, NJ energy code requirements.
