Blower Door Test in Fieldsboro, NJ

How Is A Blower Door Test Conducted?

For blower door test in Fieldsboro, 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. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.
