Air Duct Cleaning in Lucas Valley-Marinwood, CA

Frequently Asked Questions

My Eichler never had ducts — the forced-air system was added later. Is that retrofit ductwork worth cleaning, or should it just be replaced?

That's the right first question, and the honest answer depends on what we find when we open it up. A lot of the retrofit runs in Lucas Valley and Marinwood were pushed through soffit chases, garage plenums, or exposed overhead drops because the post-and-beam roof left almost no attic to work with. Short, tight-bent flex like that kinks easily, and a kinked or crushed section doesn't get fixed by cleaning. It needs to be re-pulled or replaced. If the flex is intact and the inner liner is sound, cleaning is worth it and usually restores airflow people assumed was just how the system ran. We inspect first and tell you which sections fall in which category rather than cleaning around a duct that's already collapsed.

What actually goes wrong with ducts in this part of the valley?

A few things come up again and again. Kinked or sagging flex at tight bends, unavoidable when a duct has to turn hard inside a soffit chase instead of running free through an attic. Loose or separated connections at garage plenums, where a retrofit system was tied in after the fact and the joint was never sealed properly; that pulls garage air into the supply. Loaded-up duct interiors from the dry-season dust and grass and oak pollen that blow in off the surrounding open space. The conventional ranch homes nearby have their own version of this with shallow attic and crawl runs that get compressed under insulation or stepped on during other work.

How fast can someone get out here?

Lucas Valley-Marinwood is a straightforward run for us, and we can usually schedule within a few days. If you're calling because of a specific problem, a room that stopped getting air, a smell coming out of the registers, or heavy smoke intake during fire season, say so when you call and we'll prioritize it. Exposed overhead drops and garage plenum work are faster to reach than a buried attic system, so some Eichler jobs actually move quicker than people expect.

Can you do it the same day I call?

Sometimes, depending on the day and whether we already have a crew in the Terra Linda and north San Rafael area. Same-day is more realistic for a single-system home with accessible overhead or soffit runs than for a larger ranch with a shallow crawl system that needs more setup. Call in the morning if you want the best shot at it. If we can't make it same-day, we'll tell you straight rather than booking you and sliding the window.

What makes one house here cost more than another?

Access and run count, mostly. An Eichler-style home where the retrofit ducting is exposed overhead or sitting in a garage plenum is quicker to work than a conventional ranch where runs are buried in a shallow attic or tight crawl and every connection takes effort to reach. Number of supply and return drops matters, as does whether we find kinked or disconnected sections that need attention beyond cleaning. Homes near the open space often carry a heavier dust and pollen load, which can add time. We walk the system with you and explain what's driving the number before anything is scheduled.
