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 Mill Valley, CA
Air duct cleaning in Mill Valley costs between $450 and $800 for a typical single-family home, and most jobs wrap up in a single visit. Mill Valley’s mix of mid-century homes, hillside builds, and damp microclimates creates specific conditions inside ductwork that flatland houses rarely see. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, led locally by Omar Haddad. Call us at (737) 727-2314 for a written price before any work starts.
Why Mill Valley Homes Are Different
Mill Valley isn’t one housing type. It’s a patchwork of 1950s ranchers along Miller Avenue, hillside contemporaries above downtown, redwood-shaded properties in Homestead Valley, and newer builds in Sycamore Park. Each one puts different debris in the ducts. Homes under heavy oak and bay canopies in places like Blithedale Canyon pull fine leaf litter and pollen through return registers. Houses near the marsh and creek sides of town, where fog settles longer, often show higher humidity readings inside duct runs, which lets dust cake harder against metal walls.
Most of the ductwork we open up here is original to the house or decades old, with fiberglass-lined or flex runs that have sagged in crawlspaces. The terrain matters too. Hillside homes on Tamalpais Valley slopes tend to have split-level systems and long vertical return drops where debris packs in tight. None of this is exotic work, but it rewards a crew that knows the difference between cleaning a duct and just moving dust around. We use negative-pressure extraction, meaning the loosened debris goes straight into the vacuum, not back into your living room.
Our Main Mill Valley Services
Three services bring most Mill Valley calls to us, and each has its own dedicated page with local pricing and detail.
Dryer Vent Cleaning in Mill Valley
Lint, moisture, and Marin County’s foggy seasons make dryer vent cleaning here a real maintenance item, not a once-a-decade curiosity. We see long vent runs on older Mill Valley homes, some snaking through crawlspaces or up exterior walls, where lint accumulates faster and harder. A slow dryer or a warm laundry room is usually the first sign. Our technicians clear the full run and verify airflow with a meter before finishing. Read the full picture for your home at Dryer Vent Cleaning in Mill Valley.
Air Duct Cleaning in Mill Valley
Whole-house air duct cleaning here means removing the actual buildup: dust, pet dander, construction debris from past remodels, and the fine particulate that Mill Valley’s tree cover keeps cycling through return air. We run Rotobrush agitation tools paired with Nikro HEPA filtration to clean supply and return runs, boots, and the plenum. It’s methodical work, and we document it with before-and-after photos for every job. Full details, including what’s included and local pricing, are on the main page: Air Duct Cleaning in Mill Valley.
HVAC Cleaning in Mill Valley
HVAC cleaning goes beyond the ducts to the mechanical heart of the system: coils, blower motor, drain pan, and the air handler itself. In Mill Valley, coastal humidity means evaporator coils grow biofilm faster than they do in inland parts of Marin. That buildup restricts airflow, raises energy use, and shortens equipment life. We clean the full air path and treat it as one connected system. See the breakdown at HVAC Cleaning in Mill Valley.
