What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in North Plainfield, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

Preparing for a Blower Door Test in North Plainfield, NJ

To get ready for blower door test in North Plainfield, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom 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 ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in North Plainfield, NJ.
