What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Cheyney, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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?

Houses in Cheyney, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Satisfying this requirement in your blower door test in Cheyney, PA helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

The State of PA and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings. Our team regularly helps home builders, contractors, and homeowners seeking blower door test in Cheyney, PA to satisfy energy code standards and close final inspections.

Through blower door test in Cheyney, PA, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. A blower door test takes only a short time to complete but can have a lasting effect on your home’s comfort and energy efficiency through PA’ hot and cool seasons.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Install insulation with the appropriate R-value and ensure it is correctly fitted 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Cheyney, PA

To properly prepare for blower door test in Cheyney, PA, the HVAC system and all bathroom and kitchen fans are turned off. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Cheyney, PA.
