What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Fairview Village, 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?

During blower door test in Fairview Village, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

Properties in Fairview Village, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Passing this threshold during your blower door test in Fairview Village, PA ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Fairview Village, PA

Getting ready for blower door test in Fairview Village, PA involves turning off all heating, cooling, and exhaust ventilation systems. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Fairview Village, PA.
