Blower Door Testing in Massachusetts

HERS Rating Specialist provides certified blower door testing throughout Massachusetts for new construction homes, additions, renovations, HERS ratings, and Massachusetts energy code compliance.

Our blower door testing services help builders, homeowners, and developers measure air leakage in buildings to ensure projects meet the Massachusetts Stretch Energy Code and qualify for energy efficiency programs such as Mass Save.

What Is Blower Door Testing?

A blower door test measures how much air leaks in and out of a home or building. The test uses a calibrated fan installed in an exterior doorway to depressurize the building and measure air infiltration levels.

The results are measured in ACH (air changes per hour) and determine whether a home meets energy code requirements. Excessive air leakage can cause higher energy bills, drafts, moisture problems, and poor indoor comfort.

Why Blower Door Testing Is Required in Massachusetts

• Required for new construction homes
• Required for many additions and major renovations
• Required for HERS ratings
• Required to meet Massachusetts Stretch Energy Code
• Used to verify building energy efficiency

Benefits of Blower Door Testing

• Identifies hidden air leaks
• Improves home comfort
• Reduces heating and cooling costs
• Improves indoor air quality
• Ensures compliance with building codes

When Blower Door Testing Is Performed

Blower door testing is typically completed near the end of construction before final inspection. The test verifies that the building envelope is properly sealed and meets the required air leakage limits.

Many projects combine blower door testing with other energy testing services such as duct leakage testing and HERS rating verification.

Blower Door Testing for HERS Ratings

Blower door testing is a key component of the HERS rating process. The results help determine the energy performance of the building and ensure it meets Massachusetts energy code requirements.

Accurate testing helps projects qualify for energy efficiency incentives and avoid costly corrections during final inspections.
