What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Bryn Athyn, PA helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Bryn Athyn, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 Bryn Athyn, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Meeting this benchmark in your blower door test in Bryn Athyn, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

Both PA and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. We frequently assist home builders, contractors, and homeowners who need blower door test in Bryn Athyn, PA to comply with energy codes and finalize building permits.

Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Bryn Athyn, PA

Getting ready for blower door test in Bryn Athyn, PA involves turning off all heating, cooling, and exhaust ventilation systems. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Bryn Athyn, PA energy standards.
