What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Lindewold borough, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

Preparing for a Blower Door Test in Lindewold borough, NJ

To prepare a home for blower door test in Lindewold borough, NJ, we shut off the HVAC system and disable all exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Lindewold borough, NJ energy efficiency codes.
