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. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Glenolden, PA helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Glenolden, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes in Glenolden, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Reaching the target during your blower door test in Glenolden, PA guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Glenolden, PA

When preparing for blower door test in Glenolden, 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 the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Glenolden, PA.
