Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Wynnewood, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

Homes built in Wynnewood, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Passing this threshold during your blower door test in Wynnewood, PA ensures both energy savings and full compliance with local regulations.

Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of 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.
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 Wynnewood, PA

Before starting blower door test in Wynnewood, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Wynnewood, PA.
