What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Spring Mount, PA locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Spring Mount, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

Preparing for a Blower Door Test in Spring Mount, PA

When preparing for blower door test in Spring Mount, PA, we first switch off the home’s heating, cooling, and exhaust systems. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Spring Mount, PA.
