What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Laurel Springs, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

Preparing for a Blower Door Test in Laurel Springs, NJ

To get ready for blower door test in Laurel Springs, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Laurel Springs, NJ building codes.
