What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Westampton township, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. 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?

In Westampton township, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Meeting this level during your blower door test in Westampton township, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Westampton township, NJ

To prepare for blower door test in Westampton township, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Westampton township, NJ energy code requirements.
