What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Milford Square, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Milford Square, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.

What Is A Passing Blower Door Test Score?

Homes throughout Milford Square, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this level during your blower door test in Milford Square, PA supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Milford Square, PA

Before starting blower door test in Milford Square, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside 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 the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Milford Square, PA.
