What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Upper Saddle River, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Satisfying this requirement in your blower door test in Upper Saddle River, NJ helps optimize energy use and ensures you meet local building standards.

Preparing for a Blower Door Test in Upper Saddle River, NJ

We begin blower door test in Upper Saddle River, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned 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 house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Upper Saddle River, NJ building codes.
