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 $390 and $890 for a full home, depending on square footage, ductwork age, and how the canyon damp has affected the inside of your system. Most Mill Valley homes run higher than the Marin average because our marine fog keeps duct interiors damp year-round, which means dust and organic debris cling to the walls instead of blowing loose. Morton’s Air Duct Cleaning serves Mill Valley with written upfront pricing on every job. Call (323) 918-4345 to get a specific quote for your house.
Why Mill Valley Homes Are Different
Mill Valley sits in a redwood-and-bay-laurel canyon that holds marine fog far longer than the flatland cities east of 101. That persistent moisture works its way into crawl spaces, return boots, and trunk lines, where it turns ordinary household dust into a sticky film that standard agitation will not remove. In a Corte Madera condo or a Larkspur rancher, dust stays loose and sweeps out easily. In Mill Valley, it clumps to the galvanized surfaces and requires real mechanical scrubbing with equipment built for the job, like our Rotobrush and Nikro systems.
The housing stock adds its own complication. Many Mill Valley homes date from the 1910s through the 1960s, a mix of rebuilt craftsman bungalows and hillside ranches on steep, shaded lots. Original flex or galvanized ductwork in those older homes often routes through damp crawl spaces where moisture intrusion is constant, not occasional. Our technicians regularly pull redwood needle fragments, bay laurel leaf debris, and fern spores out of return-air boots on hillside streets like those above Cascade and Blithedale. In the canyon’s near-constant dampness, that organic material seeds mold inside ducts in a way we almost never see in drier Marin towns.
There is also the wildfire factor. Mill Valley is classified among California’s highest wildfire-risk communities. During regional fire events, HVAC systems pull smoke particulates and ash into the ductwork. Post-fire duct cleaning here is a real, documented need, not a routine upsell. We tell every Mill Valley homeowner the same thing: if you smelled smoke in the house during fire season, some of what you smelled is now inside your ducts, and it should come out.
Our Main Mill Valley Services
The two jobs Mill Valley homeowners call us about most are full-system air duct cleaning and dryer vent cleaning. Each has its own dedicated Mill Valley page with pricing and detail.
Air Duct Cleaning in Mill Valley
Mill Valley’s damp, organic load inside ductwork means a proper clean here takes longer than the county average, and it is not a job for a quick vacuum pass. Our crews use Rotobrush and Nikro agitation equipment to break the tacky film that canyon humidity creates, then remove the loosened debris, including the redwood needles and fern spores that collect in older hillside homes. We protect floors with shoe covers and drop cloths from the moment we walk in, and we give you a written price before any work starts. Details and Mill Valley-specific pricing are on the Air Duct Cleaning in Mill Valley page.
Dryer Vent Cleaning in Mill Valley
Dryer vents in Mill Valley clog with more than lint. The same damp air that makes ducts sticky also compacts lint inside vent runs, especially in older homes where the vent pipe is long or has multiple elbows. We clean the full run from dryer to exterior, clear any bird or rodent nesting we find, and confirm airflow at the termination point before we leave. Like every Morton’s job, it comes with a written price first and a photo of the finished work. See the Dryer Vent Cleaning in Mill Valley page for details.

What pushes a Mill Valley quote higher than the same house in Larkspur or Kentfield is almost always the same thing: older ductwork with long horizontal runs through damp crawl spaces, or wildfire residue that needs thorough removal rather than a light pass. Whatever the number, it is on paper before we touch anything, and it does not change when the job is done.
