What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Newtown, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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 air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

In Newtown, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Complying with this benchmark during a blower door test in Newtown, PA helps cut energy expenses and meet local building regulations.

Apply insulation of the correct R-value and make sure it fits snugly in all areas 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.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.

Preparing for a Blower Door Test in Newtown, PA

Getting ready for blower door test in Newtown, PA involves turning off all heating, cooling, and exhaust ventilation systems. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Newtown, PA.
