Duct sealing in Naglee Park

Period homes near downtown with later ductwork threaded through the attic.

If the house has central ducts, we can seal the transitions that were added when air conditioning went in. Wall-furnace homes are a different job, and we will say so.

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.
