What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Maplewood, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Maplewood, NJ energy code requirements.
