What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Green Lane, PA identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Green Lane, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Green Lane, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Passing this requirement during a blower door test in Green Lane, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Green Lane, PA

To get ready for blower door test in Green Lane, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Green Lane, PA efficiency codes.
