What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Brandamore, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare 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 starts pulling air out, external air enters through the smallest cracks and leakage points. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Brandamore, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving this standard in your blower door test in Brandamore, PA lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Brandamore, PA

Getting ready for blower door test in Brandamore, PA involves turning off all heating, cooling, and exhaust ventilation systems. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Brandamore, PA efficiency standards.
