Blower Door Test in Saint Peters, PA

How Is A Blower Door Test Conducted?

To execute blower door test in Saint Peters, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the PA climate.
