What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Pottstown, PA locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Pottstown, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

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 data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes in Pottstown, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally.

Reaching this target in your blower door test in Pottstown, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Pottstown, PA

Preparation for blower door test in Pottstown, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Pottstown, PA efficiency codes.
