Duct sealing in Evergreen

East-side homes with upstairs rooms that never match the thermostat.

Evergreen two-story plans lose airflow on the upper branches first. A test shows whether the fix is a seal or a damaged run.

The visit is the same across San Jose: leakage test, internal seal if the ducts are intact, and a written before-and-after. You do not need to empty the attic or open ceilings.
