Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Toms River township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

Preparing for a Blower Door Test in Toms River township, NJ

Before starting blower door test in Toms River township, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining 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. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Toms River township, NJ energy code requirements.
