What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Hamilton township (Atlantic), 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. 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 device, we assess how the pressure from the fan differs from the home’s natural air pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

Preparing for a Blower Door Test in Hamilton township (Atlantic), NJ

For blower door test in Hamilton township (Atlantic), NJ, preparation includes turning off all heating and air conditioning units, plus bathroom 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 all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Hamilton township (Atlantic), NJ energy code requirements.
