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. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Glenmoore, 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?

To complete blower door test in Glenmoore, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

Construction in Glenmoore, PA must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching this target in your blower door test in Glenmoore, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Glenmoore, PA

To prepare a home for blower door test in Glenmoore, PA, we shut off the HVAC system and disable all exhaust fans. 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Glenmoore, PA building codes.
