What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Bordentown city, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Bordentown city, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. 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 the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes in Bordentown city, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test.

Preparing for a Blower Door Test in Bordentown city, NJ

To prepare for blower door test in Bordentown city, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. 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. 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. 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. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Bordentown city, NJ.
