What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Hatfield, 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?

For accurate blower door test in Hatfield, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

Properties in Hatfield, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. When your blower door test in Hatfield, PA meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Hatfield, PA

Preparation for blower door test in Hatfield, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. 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. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Hatfield, PA.
