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. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Skippack, PA helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Skippack, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under PA weather.

What Is A Passing Blower Door Test Score?

Properties in Skippack, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this benchmark in your blower door test in Skippack, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Skippack, PA

To get ready for blower door test in Skippack, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Skippack, PA.
