Blower Door Test in Woodbury Heights borough, NJ

How Is A Blower Door Test Conducted?

For blower door test in Woodbury Heights borough, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.
