Air Duct Cleaning in Dana Point, CA

Frequently Asked Questions

1. My ducts are rusting at the boots — is that something you clean, or do those runs need to be replaced?

   It depends on how far the corrosion has gone. Salt aerosol works on the metal boots and plenums in Dana Point homes, especially closer to the harbor and the bluffs, and we see it most in the older Capistrano Beach and Lantern District cottages where retrofit duct was pushed into tight crawlspaces decades ago. If the metal is surface-rusted but intact and the connections are still sealed, cleaning is worth doing and the run keeps serving. If a boot has rusted through, a flex connection has pulled loose, or the liner inside an old run is deteriorating, cleaning won't fix it and we'll tell you that instead of taking the job. We can usually give you a straight answer once we have a camera in the run.

2. What goes wrong with ducts here that doesn't happen inland?

   Two things, mostly. First is corrosion at metal boots and plenums from the salt in the air, which gets into even well-kept systems. Second is condensation during the long fog season: cold supply runs sweat, and damp plus settled dust is what produces the musty smell people call about. On the hillside and raised-foundation homes, the crawlspace duct sits in the dampest part of the house, so that's usually where we find the worst of it. The 1970s-90s tracts up in Monarch Beach and Niguel Shores have attic flex instead, which has its own problems, including crushed runs, sagging bellies that collect dust, and tape joints that let go in attic heat.
