Air Duct Cleaning in Larkspur, CA

Frequently Asked Questions

My house is in Baltimore Canyon and the crawlspace always smells damp. Is that coming through the vents?

Often, yes. A lot of the older canyon stock has sheet metal ducts running through an underfloor space that stays cool and humid most of the year, with the redwood shade keeping it from drying out. When the furnace kicks on, air moving through that metal picks up the crawlspace smell and carries it into the rooms. Cleaning the ducts helps, but we'll also tell you honestly if what you're smelling is the crawlspace itself: loose duct joints, failed mastic, or a return pulling from under the floor. That's a repair conversation, not just a cleaning one.

How soon can someone actually get out here?

Larkspur is a small service area and we're usually working somewhere in Ross Valley already, so scheduling is typically within a few days rather than weeks out. The thing that moves the date is access. Downtown cottages and canyon homes often have a tight crawlspace hatch, a narrow side yard, or parking that only works at certain times of day, so we ask about that when you book instead of discovering it on the truck.

I'm in a condo near Larkspur Landing with a closet unit. Is duct cleaning even worth it with such short runs?

Sometimes, sometimes not, and we'd rather say so. The flex runs off a closet or rooftop unit are short, so there's less duct to foul than in a house. What builds up in multifamily is different: kitchen grease that migrates through shared corridors and common exhaust paths, plus whatever the shoreline salt air brings in on the intake side. If your returns and the first few feet of flex are coated and the rest is clean, a focused cleaning plus filter and coil attention is the honest answer rather than a full system job.

What usually goes wrong with ducts around here?

Two patterns, split by where you live. In the older canyon and downtown homes, it's crawlspace sheet metal that's corroded at the seams, insulation that's sagged or absorbed moisture, and flex that's been crushed or disconnected by someone working under the floor. Creek-corridor humidity speeds up all of it. In the 1960s-80s condos and townhomes, it's compact units with flex runs that have kinked behind a closet wall, plus grease loading at the returns. Salt air near the shoreline is harder on the equipment and exterior rooftop components than on the ducts themselves.

What drives the cost up or down on a Larkspur home?

Mostly access and duct type. A canyon home where the whole trunk is in a low, damp crawlspace takes longer than a condo with a closet unit and six short runs, and if the underfloor clearance is tight, that's real time on the clock. Register count matters, and so does condition. Ducts with moisture damage or corroded joints may need sealing or sections replaced, which is separate from cleaning, and we'll separate it on paper too. A compact multifamily system is generally the lighter end of the work; a multi-level canyon house with original metal is the heavier end.
