How Is A Blower Door Test Conducted?

For accurate blower door test in Bogota, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house.

A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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.
