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.

AfterFast, Reliable Air Duct Cleaning Across Tamalpais-Homestead Valley
Air duct cleaning in Tamalpais-Homestead Valley typically runs $450-$850 for a full residential system, with most jobs scheduled within a few days and completed in a single visit.

Call (323) 918-4345 for a free written estimate before any work starts.
Tamalpais-Homestead Valley isn’t a grid of tract homes. It’s a winding collection of 1940s-1960s hillside cottages and cabins, many originally built as weekend retreats among the redwoods, later converted to full-time living with ductwork retrofitted through tight, damp spaces beneath pier-and-post foundations. That history matters when you’re choosing who cleans your ducts. Our technicians arrive with Rotobrush and Nikro equipment sized for these access challenges, and we price by the complete system, not by the vent, so you know the full cost before we open the first grille.
We dispatch from our San Francisco Bay Area office, with crews serving Tamalpais-Homestead Valley locally. That means we understand the specific problems the fog belt creates: crushed flex runs from decades of hillside settling, mold colonization in chronically moist crawl spaces, and the distinctive spring pollen loads that clog return-air grilles faster than ordinary household dust. We’ve been part of the Cedarwell family since 2005, and every job carries our 365-Day Done Right Promise.
Why Morton’s Air Duct Cleaning Is Tamalpais-Homestead Valley’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Tamalpais-Homestead Valley by solving problems that generic duct cleaners miss.

Our technicians don’t just vacuum registers; they inspect the full system for disconnected or crushed runs, then show you what they found with camera footage before quoting any repair.
Our customers in Tamalpais-Homestead Valley mention the same things in their feedback: the written price upfront with no changes, the shoe covers and drop cloths that protect their floors from the moment we arrive, and the photo of the clean-up we send before leaving. Background-checked, uniformed technicians working to the Cedarwell C.A.R.E. values mean your home is treated like someone’s actual home, not a job site. We work quietly around nap schedules when needed, and we choose pet-safe products where they’re available.

Air Duct Cleaning Services in Tamalpais-Homestead Valley
Air Duct Cleaning Services in Tamalpais-Homestead Valley address the unique accumulation patterns of hillside homes in the Mount Tamalpais fog belt, where decades of redwood pollen, tanoak debris, and moisture-driven microbial growth coat duct interiors far beyond what standard household dusting can reach. A typical full-system residential clean here runs $450-$850, with larger homes or systems requiring significant repair work toward the higher end. Most Tamalpais-Homestead Valley homeowners schedule cleaning when they notice persistent musty odors, increased allergy symptoms, or visibly clogged return-air grilles each spring.
Our Air Duct Cleaning team follows a thorough protocol designed for these conditions. We seal registers, apply negative pressure with HEPA filtration, and use mechanical agitation to dislodge buildup from duct walls without releasing contaminants into your living space. For homes in Tamalpais-Homestead Valley, we pay particular attention to crawl space and attic runs where fog-belt moisture has created ideal conditions for mold colonization.
Residential System Cleaning
Most Tamalpais-Homestead Valley homes we serve are single-family residences built between the 1940s and 1960s. We clean supply ducts, return ducts, and the main trunk line as one integrated system, checking for disconnected branches or crushed flex runs as we work. The written price covers the complete system, not a per-vent count that balloons at checkout.
Post-Cleaning Treatment Options
Where our inspection reveals microbial growth inside duct interiors, we offer antimicrobial treatment using products selected for safety around children and pets. This step is more commonly needed in Tamalpais-Homestead Valley than in drier Marin communities because of the persistent crawl space moisture that feeds mold colonies year-round.

HVAC Duct Cleaning in Tamalpais-Homestead Valley
HVAC Duct Cleaning in Tamalpais-Homestead Valley requires equipment and expertise matched to the access challenges of hillside construction, where ductwork often runs through tight, damp crawl spaces beneath pier-and-post foundations rather than full basements or accessible attics. A typical residential HVAC duct cleaning here costs $450-$850, with commercial or multi-zone systems priced on inspection. We recommend this service every 3-5 years for most Tamalpais-Homestead Valley homes, though homes backed directly against the redwood-tanoak forest edge may need more frequent attention due to heavier biological particulate loads.
Our crews use professional-grade Rotobrush and Nikro negative-pressure systems with HEPA containment, sized for the flexible and galvanized sheet-metal ducts common in this area’s mid-century housing stock. We don’t use rental-grade equipment that lacks the suction power or filtration to handle the dense accumulation these fog-belt systems develop. Every HVAC duct cleaning includes a video inspection of accessible runs so you see the condition before and after.
Video Inspection and Documentation
Before any cleaning begins, we feed a camera through accessible duct runs to identify crushed, disconnected, or heavily colonized sections. This step is essential in Tamalpais-Homestead Valley, where hillside settling and decades of moisture exposure have damaged ductwork that a surface cleaning would miss entirely. You see the footage; we explain what it means for airflow and indoor air quality.
System Repair and Sealing
Cleaning alone won’t restore airflow through a duct that’s crushed or disconnected at the air handler. When our inspection finds these conditions, common in the retrofitted crawl spaces of local hillside cabins, we reconnect and seal runs with materials rated for the damp environments these ducts occupy. The repair work is quoted separately, with a written price, before any additional labor begins.
Trusted Brands We Service in Tamalpais-Homestead Valley
We clean and service ductwork connected to equipment from Honeywell, Aprilaire, and Abatement Technologies, brands we encounter regularly in Tamalpais-Homestead Valley’s upgraded and original HVAC systems. Our vans carry common fittings, sealants, and replacement components sized for these manufacturers’ specifications, so most repairs don’t require a return trip. When a cabin off Panoramic Highway or Edgewood Avenue needs a specific Honeywell media filter or an Aprilaire humidifier pad replaced during the cleaning visit, we typically have it on hand. That local inventory means faster completion and fewer scheduling headaches for families who’ve already waited long enough to address their duct problems.
Common Air Duct Cleaning Problems We See in Tamalpais-Homestead Valley Homes
- Crushed or disconnected flex runs in crawl spaces. Ductwork retrofitted through tight spaces beneath pier-and-post foundations gets compressed during decades of hillside settling. We’ve found runs in Tamalpais-Homestead Valley crawl spaces that were completely flattened or pulled loose from the air handler, blowing conditioned air into the dirt year-round.
- Mold colonization from chronic fog-belt moisture. The marine layer that lingers on Mount Tam’s southwest slopes keeps crawl space humidity high even in summer. Galvanized and flexible duct interiors in these conditions develop mold that a register-only cleaning or surface wipe never reaches.
- Biological particulate overload from forest edge exposure. Homes backed against the redwood-tanoak canopy accumulate redwood pollen, tanoak catkin debris, and forest spores in return-air grilles each spring. The buildup looks like ordinary dust until allergy symptoms spike and filters clog within weeks of replacement.
- Aging galvanized sheet metal with deteriorated seams. Original ducts in 1940s-1960s cabins were often galvanized steel that corrodes in damp crawl spaces. We find seams that have separated, leaking conditioned air and drawing in musty crawl space air through the gaps.
Pricing for Air Duct Cleaning in Tamalpais-Homestead Valley, CA
A full residential air duct cleaning in Tamalpais-Homestead Valley typically costs between $450 and $850, depending on system size, accessibility, and whether we find disconnected or damaged ductwork that needs repair. We do not quote per-vent prices or advertise teaser rates that change once we’re in your home. One flat price per system, agreed in writing before any work starts, every time.
What moves a job toward the higher end: multiple zones, significant mold colonization requiring antimicrobial treatment, or crushed and disconnected runs that need reconnection and sealing. What doesn’t affect the price: the number of vents in your system. A small cabin with 8 vents and a large home with 20 vents pay the same system rate if the ductwork configuration is comparable.
We provide free written estimates for every Tamalpais-Homestead Valley home. Call (323) 918-4345 to schedule. You’ll receive a firm price by email before we dispatch, with no obligation to proceed.

FAQs About Air Duct Cleaning in Tamalpais-Homestead Valley
Tamalpais-Homestead Valley’s fog-belt climate and hillside construction create duct problems rarely seen in grid-built, sunnier Marin towns. The persistent marine layer moisture colonizes crawl space ductwork with mold, while decades of hillside settling crush or disconnect retrofitted flex runs beneath pier-and-post foundations. Our crews come prepared for these specific conditions with camera inspection capability, antimicrobial treatment options, and repair materials sized for damp environments. Call (323) 918-4345 for a free estimate on your system.
We find aging galvanized sheet metal with corroded seams, flexible duct runs crushed by hillside settling, and mold colonization fed by chronic crawl space moisture. On a 1950s cabin off Edgewood Avenue backed against the redwood-tanoak edge, our tech pulled a return-air grille packed with redwood pollen and tanoak catkin debris, then ran camera inspection through the crawl space beneath the pier-and-post foundation and found a crushed flex run feeding the rear bedroom and a disconnected branch at the air handler. We reconnected and sealed the runs, cleaned supply and return ducts under negative pressure with HEPA filtration and agitation tools, and treated the interior for the mold colonization the fog-belt crawl space had been feeding all year. Call (323) 918-4345 to schedule inspection of your cabin’s system.
We feed a video camera through accessible duct runs during our pre-cleaning inspection, showing you real-time footage of the duct interior. In Tamalpais-Homestead Valley’s tight crawl spaces, we also check airflow at each register and listen for whistling or dead zones that indicate blockages or disconnections behind walls. This inspection is included with every full-system cleaning quote, with no charge if you choose not to proceed. Call (323) 918-4345 to book.
Yes. Homes within a few hundred feet of the redwood-tanoak canopy accumulate a distinctive mix of redwood pollen, tanoak catkin debris, and forest spores that standard household dust doesn’t match. This biological particulate is denser and more adhesive than ordinary dust, coating duct walls and clogging filters within weeks of replacement. Many Tamalpais-Homestead Valley homeowners mistake this buildup for normal dust until spring allergy symptoms spike unexpectedly. Call (323) 918-4345 and we’ll inspect your grilles and duct interiors to confirm what you’re dealing with.
We follow NADCA-recommended practices for source removal, including contained negative-pressure cleaning with HEPA filtration and mechanical agitation. For Tamalpais-Homestead Valley’s moisture-compromised systems, we add video verification before and after, plus antimicrobial treatment where inspection reveals active mold colonization. The hillside access challenges don’t change our standards; they just require better equipment and more patient technique. Call (323) 918-4345 to discuss your specific system.
