Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning Company in San Anselmo, CA
Air duct cleaning in San Anselmo means working around a specific set of conditions: homes built between 1910 and 1955, retrofit duct systems now 50 to 70 years old, and a valley floor that has flooded repeatedly. The result is crawl-space ductwork that often carries dried creek silt, embedded mold, and decades of debris that a standard service call doesn’t address. Linden Air Duct Cleaning handles all three core jobs here: air duct cleaning, dryer vent cleaning, and air duct repair. Call (980) 447-2498 for a written, no-hassle quote before any work begins.
Why San Anselmo Homes Are Different
San Anselmo sits at the bottom of the Ross Valley, and San Anselmo Creek has flooded the downtown and surrounding streets severely in 1982, 2005, and 2006. Homes within a few blocks of the creek, along Red Hill Avenue, Tamalpais Avenue, and lower Sir Francis Drake Boulevard, frequently show crawl-space ducts packed with dried silt from those flood events. Once creek water recedes, the silt stays. It lines the inside of return ducts, settles into register boots, and becomes a permanent source of recirculated dust unless it is physically extracted. A standard negative-pressure cleaning will not touch it; the debris has to be agitated and pulled out section by section.
Beyond flooding, the valley bowl itself does something to ductwork that neighboring hillside towns do not experience. Evening marine fog rolls in from the coast and settles in the low pockets, keeping crawl spaces damp well into summer. That persistent moisture accelerates mold colonization inside flex duct liners and at poorly sealed register boots. Homes with older rigid galvanized runs, retrofitted for central heating in the 1950s through 1970s, often have disconnected joints where damp air enters and debris accumulates. We see this pattern on the valley floor more aggressively than on the drier ridgelines a mile away.
Our Main San Anselmo Services
Most San Anselmo homeowners call us for one of two reasons: the ducts haven’t been cleaned since the house was purchased, or a dryer vent has become a fire and efficiency problem. Here’s what each job involves in this town specifically.
Air Duct Cleaning in San Anselmo
San Anselmo duct cleaning jobs often mean crawl-space access, so our crews arrive with HEPA-filtered negative-pressure equipment from Nikro and Rotobrush that can reach duct runs under low floors. We start by inspecting the system, then use agitation tools to loosen packed debris, including dried silt from past creek floods. The extraction pulls loosened material into the vacuum, not back into the living space. After the cleaning, we seal register boots and check joints for disconnects, which are common in 50-to-70-year-old retrofit systems. Air Duct Cleaning in San Anselmo covers full-system pricing and what to expect.

Dryer Vent Cleaning in San Anselmo
Older San Anselmo homes often have dryer vent runs that are longer than modern code allows, with turns that trap lint fast. In damp crawl spaces, that lint absorbs moisture and clumps, restricting airflow and raising the dryer’s operating temperature. We clean the full run from the dryer to the exterior termination, including the lint trap bypass, using a rotary brush and HEPA vacuum. The job ends with an airflow test at the exterior vent. Dryer Vent Cleaning in San Anselmo includes pricing and the written guarantee on every job.

Air Duct Repair in San Anselmo
Disconnected joints, crushed flex runs, and rusted register boots are common in San Anselmo homes with original ductwork. A disconnected joint in a crawl space means the HVAC system is heating or cooling the dirt under the house, not the rooms above. We repair and re-secure joints with mechanical fasteners and mastic sealant, replace damaged flex sections, and re-seal register boots. Every repair carries a written 365-Day Done Right guarantee, and if a covered repair fails, we return at no charge. Air Duct Repair in San Anselmo explains what a repair inspection covers.

FAQs About Air Duct Cleaning Company in San Anselmo
No. Duct cleaning is a maintenance service and does not require a permit from the Town of San Anselmo. Repairs that are inside the existing duct system, such as joint re-sealing or flex run replacement, also do not typically require permits because they do not alter the building envelope. If a job ever crosses into territory that needs a permit, we will tell you before work starts.

"Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."

- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N.
