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 typically runs between $480 and $780 for a whole-house system in an average three-bedroom home, though flood-prone properties near the creek often run higher because of the additional sediment work involved. Kestrel Air Duct Cleaning works throughout the Ross Valley, and our techs know this town’s older housing stock well. If you’ve got damp crawl spaces, retrofitted duct runs, or a house that’s been through one of the creek’s flood events, call (469) 972-3151 for a straight answer and a written price before any work starts.
Why San Anselmo Homes Are Different
San Anselmo sits on the Ross Valley floor along San Anselmo Creek, and that geography shapes nearly every duct job here. Neighborhoods in the lower downtown corridor and streets closest to the creek have a documented flood history, with major events in 2005 and 2006 pushing water and silt into residential crawl spaces. For homeowners, that means duct sections that run below grade often carry sediment tide marks or microbial staining long after the water itself receded.
Most of the housing stock dates from before 1960. Craftsman bungalows, Tudor Revival cottages, and early ranch homes dominate, and almost all of them had forced-air systems added years after construction. That retrofit history produces non-standard duct runs through tight crawl spaces and wall cavities, often with sheet metal, duct board, and flex duct spliced together in a single system. Add the Ross Valley’s bowl geography, which traps marine fog and cool air overnight, and you get crawl spaces that stay damp through much of the year. Dust binds to that moisture, and mold follows. Homes in San Anselmo simply present a different set of conditions than ridge-top or bayside Marin communities, and the work has to account for that.
Our Main San Anselmo Services
Two jobs account for nearly every call we take from San Anselmo homeowners. Each has its own page with full details, local pricing, and what to expect when we arrive.
Air Duct Cleaning in San Anselmo
Older San Anselmo homes frequently carry years of accumulated debris, and flood-prone properties add sediment that settles in low duct runs. Our Air Duct Cleaning in San Anselmo page covers how we use negative-air extraction to pull contaminants out while HEPA filtration keeps loosened particles from re-entering your living space. We inspect for moisture staining and mold colonization, especially in crawl-space duct sections, and document what we find so you can see the before and after.
Dryer Vent Cleaning in San Anselmo
Dryer vents in older San Anselmo homes often run long horizontal distances through tight crawl spaces, and lint builds up fast when airflow is already restricted by retrofitted routing. Our Dryer Vent Cleaning in San Anselmo page explains the process, including how we bypass the lint trap and clear the full run to the exterior vent. A clogged vent in a damp crawl space is a fire risk and a mold invitation, and the work is more involved here than in newer construction.

What San Anselmo Customers Say
"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
