Blower Door Testing Princeton, MA

Blower Door Testing in Princeton, MA

HERS Rating Company provides certified blower door testing in Princeton, Massachusetts. Our RESNET-accredited technicians use calibrated equipment to precisely measure your building’s air leakage rate — delivering the documentation you need for code compliance, permit sign-off, and Mass Save incentives.

What Is a Blower Door Test?

A blower door test uses a powerful, calibrated fan temporarily installed in a doorway to pressurize or depressurize your home. By measuring airflow at a standardized pressure of 50 Pascals, we determine exactly how much air is leaking through the building envelope — expressed as ACH50 (air changes per hour).

Under the Massachusetts Stretch Energy Code (IECC 2021), new homes in Princeton must achieve 3.0 ACH50 or less. We perform the test and provide all documentation required by the Princeton building department.
