What Our Clients Say
How Is A Blower Door Test Conducted?
When blower door test in Lewes, DE is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.
When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in DE climates.
