Blower Door Test in Emerson, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in Emerson, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.
