Blower Door Test in Mo DEna, PA

How Is A Blower Door Test Conducted?

While performing blower door test in Mo DEna, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

Homes throughout Mo DEna, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
• Install insulation that meets the required R-value and check that it’s evenly and securely placed throughout the 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.
• Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
• Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
