Blower Door Testing in city, TX

How Is A Blower Door Test Conducted?

To perform Blower Door Testing in city, state, TX, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in Texas.

What Is A Passing Blower Door Test Score?

In city, state, TX, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. When your blower door test in city, state, TX meets this requirement, you benefit from reduced energy bills and code compliance.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
• 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.
• Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
• Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
• Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>
