What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Birchrunville, 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?

When performing blower door test in Birchrunville, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Birchrunville, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this requirement during your blower door test in Birchrunville, PA helps reduce energy costs while keeping your home compliant with local building codes.

Fit insulation with the correct R-value and make sure it’s installed without voids across the entire building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Birchrunville, PA

Before conducting blower door test in Birchrunville, PA, we make sure all heating, cooling, and ventilation fans are switched off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area 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 the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Birchrunville, PA energy standards.
