What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Southeastern, 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?

When conducting blower door test in Southeastern, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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 pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

Preparing for a Blower Door Test in Southeastern, PA

When preparing for blower door test in Southeastern, PA, we first switch off the home’s heating, cooling, and exhaust systems. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside 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 depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Southeastern, PA.
