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.

AfterAir Duct Cleaning Company in San Anselmo, CA
Air duct cleaning in San Anselmo runs $420-$780 for a typical 3-4 bedroom home, with pre-1940s homes on raised foundations running higher because the crawl-space access is tighter and the duct runs are longer than anything you’ll find in newer construction. We’re Morton’s Air Duct Cleaning, and we’re the San Anselmo duct specialists with a written price before any work starts, professional Rotobrush and Nikro equipment, and a 365-Day Done Right Promise on every job. Call (323) 918-4345 for a quote tailored to your house.
Why San Anselmo Homes Are Different
San Anselmo sits at the base of the Ross Valley where multiple branches of San Anselmo Creek come together, and that geography shapes the ductwork in ways that don’t apply a few miles up the hill in Fairfax or over in San Rafael. The town flooded hard in 2005 and 2006, and water that got into crawl spaces and subfloor duct runs left its mark. Metal ducts that sat in floodwater and were never sanitized afterward can still carry mold colonies in the low-lying sections, even when the visible parts of the house look fine. A standard cleaning that skips antimicrobial treatment won’t touch that.
The housing stock adds its own layer. Most San Anselmo homes are Craftsman bungalows, Colonial Revivals, and Victorian-era cottages built between roughly 1905 and the 1940s, nearly all on raised foundations with exposed crawl spaces. Those original sheet-metal duct runs snake through framing that predates modern HVAC design. Access hatches are small, clearances are low, and the runs bend in ways that make cleaning slower, more deliberate work. It’s a very different job from the slab-on-grade homes that make up most of Marin’s newer stock.
Then there’s the fog. The Ross Valley funnels marine moisture inland and holds it, especially on winter mornings. That persistent humidity keeps uninsulated metal ducts damp longer after any moisture event and speeds up dust-mite and mold spore buildup. A San Anselmo house with forty-year-old ducts in a damp crawl space isn’t an edge case here. It’s the norm.
Our Main San Anselmo Services
San Anselmo homeowners call us for two jobs more than anything else. Both get the same upfront written pricing, the same shoe covers and drop cloths on every visit, and the same 365-Day Done Right Promise.
Air Duct Cleaning in San Anselmo
This is full-system cleaning: supply and return ducts, registers, the blower compartment, and the air handler. In San Anselmo, we pay particular attention to the low duct runs near the crawl-space entry points, which is where 2005 and 2006 flood moisture would have pooled and where condensation from the valley fog tends to collect. Our technicians use Rotobrush agitation and Nikro HEPA-filtered collection to pull debris out without scattering it through the house. Before any work starts, you’ll have a written price for the whole system. If your home floods, or you suspect it did years ago, we’ll talk through sanitizing options before cleaning so the underlying issue doesn’t come back. See Air Duct Cleaning in San Anselmo for the full walkthrough.
Dryer Vent Cleaning in San Anselmo
Dryer vents in older San Anselmo homes often run up through walls or across crawl spaces with multiple elbows, which traps lint faster than a straight vent run in a newer house. We clean the full vent path from the dryer connection to the exterior termination, using professional equipment to break up the packed lint and remove it. It is quiet work, and we’re happy to schedule around nap times if you’ve got a little one sleeping. Before the crew leaves, you’ll get a photo of the clean vent run and a written record of what was removed. See Dryer Vent Cleaning in San Anselmo for the complete details.

What San Anselmo Customers Say
"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
- Shelby Dunham"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
