What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Woxall, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Woxall, PA is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.

What Is A Passing Blower Door Test Score?

Residential buildings in Woxall, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving this goal during your blower door test in Woxall, PA promotes energy savings and demonstrates adherence to local building rules.

Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
Use insulation featuring the proper R-value and verify complete, gap-free coverage across 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.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.
Most building departments provide detailed compliance resources — view the Philadelphia checklist example here.

Preparing for a Blower Door Test in Woxall, PA

For blower door test in Woxall, PA, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. 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. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Woxall, PA efficiency standards.
