Air duct repair and replacement
A damaged duct can send conditioned air into the attic or crawl space, leaving rooms with weak airflow. We repair accessible damage where that's practical and replace sections when repair won't solve the problem.
Common signs of a duct problem
- One or two rooms stay warmer or colder than the rest
- Weak airflow at particular vents
- Torn insulation or visible gaps in an attic or crawl space
- Flex ducts that are crushed, sagging or kinked
- Dust that keeps returning soon after cleaning
Repair or replace?
A loose connection or small leak may only need a repair. Ducts that are old, heavily damaged or badly routed may be better replaced, at least in part. We'll show you photos of what we find and explain both options where they apply.
Coastal attics and crawl spaces
Damp, salty air can be hard on metal parts and fasteners near the coast, and rodents can damage flex duct in any attic. It's worth checking the condition of your ducts before paying to clean them, since damaged sections may need attention first.
Permits and code
Some replacement work needs a permit or has energy-code requirements in California, including possible duct testing. We'll tell you what applies before you agree to the work.

Frequently asked questions
Can leaking ducts raise my energy bills?
They can. Air that leaks out before reaching the room is air you've paid to heat or cool. How much depends on the size and location of the leak.
Do I need to replace all my ducts?
Not always. If the damage is limited, a section may be enough. We'll look at the whole accessible system before making a recommendation.
Can you fix ducts in a crawl space?
Often, yes, as long as there's safe access. We'll confirm that on site.
