What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Pipersville, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Pipersville, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes in Pipersville, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Complying with this benchmark during a blower door test in Pipersville, PA helps cut energy expenses and meet local building regulations.

Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Apply the correct R-value insulation and verify that it’s properly fitted to seal the whole building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.

Preparing for a Blower Door Test in Pipersville, PA

To properly prepare for blower door test in Pipersville, PA, the HVAC system and all bathroom and kitchen fans are turned off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. 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. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Pipersville, PA efficiency standards.

Blower Door Test for Contractors in Pipersville, PA

For contractors conducting blower door test in Pipersville, PA, well-insulated homes generally require only minimal on-site corrections during the test.
