What Is Duct Leakage Testing?

Duct leakage testing (also called duct blaster testing) measures how much air leaks from your HVAC duct system. Using a calibrated fan connected to the duct system, we pressurize the ducts and measure leakage at 25 Pascals — reported as CFM25 (cubic feet per minute).

The Massachusetts Stretch Energy Code requires duct leakage to total (leakage to outside) of 4 CFM25 per 100 sq ft of conditioned floor area or less. We test your system and provide full documentation for the Manchester by-the-Sea building department.
