Blower Door Test in Plumsted, NJ

How Is A Blower Door Test Conducted?

During blower door test in Plumsted, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.
