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 costs $450 – $750 for a standard single-system home, and our crews complete most jobs in a single visit. San Anselmo’s mix of older hillside homes and renovated mid-century ranches means ducts here collect a specific blend of dust, pet hair, and seasonal pollen that hits harder than in flatland Marin towns. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and every San Anselmo job gets a written price before we start. Call (737) 727-2314 for a free estimate.
Why San Anselmo Homes Are Different
San Anselmo sits in a valley where fog from the coast meets warm inland air, and that creates real condensation inside duct runs that other Marin towns don’t see as much. Homes along Red Hill and Sleepy Hollow climb into steeper terrain, which means longer duct runs, more bends, and more places for debris to pack in. A significant share of San Anselmo’s housing stock dates to the 1920s through 1960s, and many of those homes still have original galvanized ductwork that sheds fine metal dust as it ages. Add in the oak and pine pollen that blows through the Ross Valley and you get a coating on duct walls that recirculates every time the furnace kicks on. We also see a lot of homes in the Seminary and downtown flats neighborhoods where remodeled kitchens and additions left construction dust inside the returns. None of this is a knock on San Anselmo; it’s just what the local housing stock and climate do, and it changes how we approach a cleaning.
Our Main San Anselmo Services
San Anselmo homeowners call us most about two jobs: cleaning the air ducts that carry heated and cooled air through the house, and clearing dryer vents that run from the laundry room to the outside. Each has its own dedicated San Anselmo page below with pricing and local detail.
Dryer Vent Cleaning in San Anselmo
Laundry rooms in San Anselmo are often tucked into basements, hall closets, or converted garages, and that means dryer vents take some creative paths to the exterior. Longer runs with more turns catch lint faster, and in an older Ross Valley home that vent may not have been opened in years. Our technicians run a rotary brush through the full length and finish with a negative-pressure pull so loosened lint goes into the collection unit, not back into your laundry room. Full details, including pricing for Dryer Vent Cleaning in San Anselmo, are on the service page.
Air Duct Cleaning in San Anselmo
Most San Anselmo duct systems have never been cleaned, and the buildup inside returns and supply branches is a mix of skin cells, pet dander, and the fine dust that settles during our dry summers. We run a Rotobrush system through every branch and use a Nikro HEPA vacuum to keep that debris from entering your living space while we work. You get before-and-after photos of the inside of your ducts so there’s no guesswork about what was actually removed. Pricing and the full breakdown live on the Air Duct Cleaning in San Anselmo page.
HVAC Cleaning in San Anselmo
The coil and blower unit inside your furnace or air handler catch whatever the filter misses, and in San Anselmo’s older homes that’s often years of accumulated film that forces the system to run longer. We clean the evaporator coil, blower wheel, and accessible plenum surfaces, then treat the system with a product from Honeywell or Aprilaire to keep film from re-forming quickly. This work gets paired with a full duct cleaning for most customers because the two jobs share the same access points. See HVAC Cleaning in San Anselmo for scope and pricing.

FAQs About Air Duct Cleaning Company in San Anselmo
Most San Anselmo appointments happen within three to five business days of your call. We don’t oversell emergency speed; we’d rather give you a real window and hit it. Every booking comes with a live trackable arrival time through The Relay Standard, so you’ll watch the tech’s progress the way you’d track a rideshare.
No. Residential air duct cleaning, HVAC cleaning, and dryer vent cleaning are maintenance work and don’t require a permit in San Anselmo or anywhere in Marin County. If during the job we spot a condition that might need licensed repair work, we’ll tell you before anything else happens and leave it to a qualified contractor if that’s the right call. Call (737) 727-2314 with any question about your home’s setup.
Yes, and it rarely comes up. Interior duct and dryer vent cleaning happens inside your home and at the existing exterior vent opening, so we’re not changing anything an HOA would need to review. If your San Anselmo association has rules about roof or exterior access, let us know when you book and we’ll plan the visit around them.
