Blower Door Test in Upperdeerfield, NJ

How Is A Blower Door Test Conducted?

For accurate blower door test in Upperdeerfield, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.
