What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Lavallette borough, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. 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 the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

Preparing for a Blower Door Test in Lavallette borough, NJ

For blower door test in Lavallette borough, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Lavallette borough, NJ.
