Even a well insulated home can waste energy if its duct system leaks. Duct leakage testing measures how much conditioned air escapes before it reaches the rooms it is meant to serve.
How Ducts Lose Air
Ductwork running through attics, basements, and wall cavities often leaks at seams, connections, and boots. Air that escapes into unconditioned space is energy you paid to heat or cool but never enjoyed, and it can pull in dust and humidity.
How the Test Is Performed
A calibrated fan pressurizes the duct system while the rater measures airflow. The result shows total leakage and leakage to the outside, both of which are compared against code limits.
The Comfort Connection
Leaky ducts cause uneven temperatures, rooms that never feel right, and an HVAC system that runs longer than it should. Sealing ducts improves comfort, lowers bills, and helps the system last longer.
Where It Fits in Compliance
Massachusetts energy code includes duct tightness requirements for many projects. We perform the testing, document the results, and advise on sealing strategies. Reach out to schedule duct testing for your build.
