Questions before you call
How do I know if my ducts need replacing?
Rooms that never get comfortable, dust around registers, high bills, ducts that are crushed, torn or disconnected in the attic, or ductwork that's 25 or more years old are the usual signs.
Do you need a permit to replace ducts in East Contra Costa?
Yes. Replacing ductwork requires a permit from your city's building division, or Contra Costa County for Bay Point, Discovery Bay, Byron, Knightsen and Bethel Island, and California requires a duct leakage test by a third-party HERS rater. We coordinate it.
Should I replace ducts when I replace my AC or furnace?
Often, yes. Doing both at once avoids paying for attic access twice, and new equipment on old leaky ducts never performs as rated.
