Duct sealing in East San Jose

Older east-side houses with central heat and air.

We seal intact duct systems in east San Jose. If the house only has a wall furnace, we will tell you sealing is not the job.

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.
