Duct sealing in West San Jose

Postwar homes near the Campbell line with central air added later.

West-side houses often gained ducts decades after they were built. We seal the trunk and branch joints that manual access cannot reach.

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.
