What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Coopersburg, 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?

To conduct blower door test in Coopersburg, PA, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Coopersburg, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. By meeting this standard in your blower door test in Coopersburg, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.

Preparing for a Blower Door Test in Coopersburg, PA

Getting ready for blower door test in Coopersburg, PA involves turning off all heating, cooling, and exhaust ventilation systems. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Coopersburg, PA.
