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.

AfterFast, Reliable Air Duct Cleaning Across San Anselmo
Air duct cleaning in San Anselmo typically runs $395 – $785 for a full system depending on home size, number of returns, and how much flood silt or mold has accumulated over the decades. Most jobs here take three to five hours in a single visit. If you’re on the valley floor near San Anselmo Creek, the work often includes crawl-space duct inspection and joint sealing that standard cleaning packages skip. Call (980) 447-2498 for a written quote before any work begins.
We know the difference between a 1920s bungalow off Tamalpais Avenue and a 1970s ranch up in Sleepy Hollow. The duct systems are not the same, and neither is the cleaning approach. Our Air Duct Cleaning team has worked in nearly every San Anselmo neighborhood, from Seminary to Lansdale to the flats near Red Hill Avenue, and we’ve learned exactly where the problem zones sit in Ross Valley homes.
Why Linden Air Duct Cleaning Is San Anselmo’s Preferred Air Duct Cleaning Company
We’ve been cleaning ducts in Marin County since 2004, and the thing that earns repeat calls from San Anselmo homeowners is simple: we name the tech before they arrive. You get the technician’s name and photo sent to you before the visit. They show a photo ID badge at the door. Every tech is background-checked and identity-verified under the Threshold Standard. For people home alone or parents with young kids, that’s the difference between dreading a service call and getting it done.
San Anselmo feedback keeps pointing at two things. One: the written price before work starts. No per-vent add-ons, no bait-and-switch conversion at the door. Two: the 365-Day Done Right Promise. If the work isn’t right, we make it right, in writing, on every job. That’s not a tagline. It’s the same standing commitment since day one.
When you call us, a live person answers. Not a voicemail loop, not a callback queue. Day or night. That matters when you’ve got a musty smell coming from the registers and you want to know what it costs to fix before the fog rolls in again.
Commercial Air Duct Cleaning in San Anselmo
Commercial Air Duct Cleaning in San Anselmo covers the retail spaces, offices, and multi-unit buildings that line Sir Francis Drake Boulevard and the downtown corridor around San Anselmo Avenue. These buildings share the same valley-floor humidity and, in many cases, the same pre-1980s duct materials as the homes nearby. The difference is occupancy: employees, customers, and tenants breathing the same recirculated air all day, so the cleaning standard needs to be stronger. A commercial job in San Anselmo typically runs $1,200 – $3,800 depending on square footage, duct accessibility, and whether rooftop units or crawl-space runs are involved. We always provide a written price for the entire building before the first register is opened.
Multi-Unit and Mixed-Use Buildings
Older two-story commercial buildings near downtown often have shared return plenums and decades of tenant turnover. That means gypsum dust, cooking residue, and in some cases, flood silt from the same creek events that hit the residential streets. We clean the full supply and return sides, not just the visible grilles.
Retail and Office Air Quality
Retail staff near San Anselmo Creek regularly complain about stale air and allergy symptoms that worsen during damp winters. A full commercial cleaning improves airflow, reduces dust on inventory and fixtures, and often helps aging rooftop units run more efficiently. We’ll inspect and clean with HEPA-filtered negative pressure so the debris we remove doesn’t redeposit into the occupied space.
Air Duct Cleaning Services in San Anselmo
Air Duct Cleaning Services in San Anselmo start with a camera inspection of exactly what’s inside your ducts before we quote the job. For most single-family homes in San Anselmo, a full system cleaning runs $395 – $685. Homes over 3,000 square feet, or those with two separate HVAC systems, fall in the $685 – $785 range. We write the price down before we start. That’s the rule, and it doesn’t change based on what we find once the register boots come off.
Full System Cleaning with Negative Pressure
We use professional-grade negative-pressure extraction equipment from Nikro, connected at the air handler, while agitating the inside of every supply and return run. This pulls loosened debris, silt, and mold fragments out of the home instead of pushing them around. For San Anselmo’s low crawl-space homes, this step is what separates a real cleaning from a surface vacuum job.
Video Inspection and Sealing
Every cleaning includes before-and-after photos of your own ducts. If the camera finds disconnected joints, crushed flex, or failed register boots, we’ll show you the footage and quote the sealing repair separately, with a written guarantee on the repair. If a covered repair fails within 365 days, the second visit is free. That combination is the honest fix for most older San Anselmo duct systems.

Trusted Brands We Service in San Anselmo
Our equipment and products come from brands that trade professionals actually use, not retail-grade kits. We run Nikro negative-pressure machines and Rotobrush agitation systems for most residential and commercial jobs, and we work with Honeywell and Aprilaire filtration products when a San Anselmo home needs media filters or air-quality upgrades after cleaning. Because we standardize on these lines, replacement filters, UV lamps, and seals are typically available for quick turnaround without waiting on special orders. If your system already uses Honeywell or Aprilaire components, our techs are familiar with the exact fitment and can source parts correctly on the first trip.
Common Air Duct Cleaning Problems We See in San Anselmo Homes
- Flood silt packed into crawl-space duct runs. Homes within a few blocks of San Anselmo Creek, especially along Red Hill Avenue and Tamalpais Avenue, often have dried creek silt inside flex duct that dates to the 1982, 2005, and 2006 floods. A routine surface vacuum won’t touch it. The debris sits low in the run and recirculates every time the air handler kicks on.
- Disconnected joints in retrofit systems from the 1950s – 70s. The original builders of San Anselmo’s Craftsman and ranch homes never planned for central air. When heating was retrofitted decades later, duct runs got crammed into crawl spaces too shallow for them. After 50 – 70 years of settling and damp soil, those joints separate, and cleaning without sealing just lets new debris back in.
- Mold recolonization at register boots from persistent valley fog. San Anselmo’s bowl topography pulls marine fog in from the coast nearly every evening. Crawl spaces stay damp well into summer. That humidity feeds mold inside flex duct liners and at poorly sealed boots, often within months of a clean if the moisture source isn’t addressed.
- Pest intrusion through crushed or torn ducts. Rodents find their way into low crawl-space duct runs, and the damage they leave behind is more than odor: torn liners, nesting material, and contamination. We’ve opened enough San Anselmo crawl spaces to recognize the signs immediately, and we’ll show you the photos.
Pricing for Air Duct Cleaning in San Anselmo, CA
Air duct cleaning in San Anselmo runs $395 – $785 for a complete single-family home system. The honest drivers of price are square footage, the number of supply and return runs, and whether the crawl space requires extra time to access safely. Homes near the creek with flood silt or mold contamination generally land at the upper end because the work includes deeper cleaning and often joint sealing. We give one flat price per system in writing before any equipment comes off the truck. No per-vent price. No final totals that surprise you. Estimates are free, and the price doesn’t move once we start. Call (980) 447-2498 and we’ll walk through what your San Anselmo home actually needs.

FAQs About Air Duct Cleaning in San Anselmo
Homes on the valley floor near San Anselmo Creek carry duct contamination from flood events in 1982, 2005, and 2006 that you won’t find in uphill neighborhoods. Dried silt and mold sit inside crawl-space duct runs, and standard surface cleaning leaves it exactly where it is. These homes need full negative-pressure extraction plus camera inspection and joint sealing to actually solve the problem. Call (980) 447-2498 for an exact quote on a creek-zone home.
Yes, and those are jobs we know well. Original rigid galvanized runs from the 1920s – 30s often have disconnected joints and debris packed into low sections from decades of use. We clean with agitation tools suited to metal ductwork, then seal the failed joints and rebuild register boots where needed. The cleaning and sealing go together for these older San Anselmo homes.
Mold in San Anselmo ducts usually shows up as dark speckling or fuzzy patches on the inside of flex duct liners and around register boots, often with a musty odor that worsens in damp weather. The first step is camera inspection, which lets us see the duct interior directly instead of guessing. If we find mold, we’ll scope the source moisture issue and recommend the right remediation path before cleaning.
Most crawl-space duct systems in San Anselmo should be cleaned every four to six years, and homes near San Anselmo Creek or with visible silt history may need attention sooner. The persistent valley humidity means mold and debris accumulate faster here than on the drier ridgelines. After your first cleaning, we’ll give you a realistic schedule for your specific home rather than a generic brochure answer.
Yes, and in many 1950s – 70s retrofit systems, sealing is the more important step. If joints are disconnected and register boots are leaking, cleaned ducts re-contaminate within months. We quote sealing repairs separately with a written guarantee, and the 365-Day Done Right Promise covers the repair if it fails. The combination of cleaning plus sealing is what actually holds up in San Anselmo’s damp crawl spaces.
