Serving Lamorinda
We serve Lafayette and Moraga from our Antioch shop, about 30 miles away via SR-4 and SR-24, including Happy Valley and Burton Valley. Large parts of Lafayette and Moraga sit in very high fire hazard zones, so good filtration and tight ductwork matter during smoke season. New ductwork in Lamorinda is permitted through the City of Lafayette or Town of Moraga planning review, then Contra Costa County building inspection and duct-leakage tested by a third-party HERS rater.

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 Lamorinda?
Yes. Replacing ductwork requires a permit from the City of Lafayette or Town of Moraga planning review, then Contra Costa County building inspection, 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.
