What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Milford Square, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Milford Square, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

In Milford Square, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Milford Square, PA helps optimize energy use and ensures you meet local building standards.

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. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to 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.
