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.

San Anselmo’s pre-WWII housing stock, creek-flood history, and shared downtown building systems create air duct challenges that generic crews miss. Our technicians know the raised foundations along Sir Francis Drake Boulevard, the tight crawl spaces in the Sleepy Hollow neighborhood, and the parking restrictions around downtown San Anselmo Avenue. That local knowledge changes what we bring, how we quote, and what we check before we pack up.
Why Morton’s Air Duct Cleaning Is San Anselmo’s Preferred Air Duct Cleaning Company
We’ve built our reputation in San Anselmo by showing up prepared for houses built in 1925, not 1995. Our Air Duct Cleaning team carries Rotobrush and Nikro equipment sized for low-clearance crawl spaces, and every technician is background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values. Shoe covers and drop cloths are standard on every visit, not optional.
San Anselmo customers tell us the same thing: previous crews quoted one price, then added per-vent charges once inside. We don’t do that. One flat price per system, agreed in writing before any tool gets plugged in. Our 365-Day Done Right Promise means if something isn’t right, we make it right. Full stop.
Calls are answered by a live person, 24/7. Not a chatbot, not a callback queue. When you’re coordinating around kids’ nap schedules or a pet who stresses around strangers, that matters.
HVAC Duct Cleaning in San Anselmo
HVAC Duct Cleaning in San Anselmo means addressing supply and return ductwork through a house built before modern HVAC design, often with original sheet-metal runs threading through damp, tight crawl spaces beneath raised foundations. A typical residential HVAC duct cleaning in San Anselmo runs $550-$850, with commercial systems starting around $1,200 depending on access and square footage. We use negative-pressure HEPA containment, rotary agitation from Rotobrush systems, and video inspection to verify source removal before we seal anything back up.
Crawl-Space Access and Moisture Remediation
San Anselmo’s pre-1940s homes sit on raised foundations with exposed crawl spaces that flood crews often skip because they’re hard to reach. We don’t. Our Nikro portable units fit where truck-mounted systems can’t, and when we find post-flood moisture in low-lying duct trunks, we flag it for antimicrobial treatment before closing the access.
Supply and Return Duct Separation
Older San Anselmo systems often have supply and return trunks that cross or share joist bays in ways modern codes wouldn’t allow. We map the airflow path before cleaning so we’re not pushing debris from one side into the other. That takes longer. It also works better.
Vent Cleaning in San Anselmo
Vent Cleaning in San Anselmo covers the visible registers and grilles, the boot connections behind walls, and the terminal duct segments where dust and pet hair actually collect. A typical vent cleaning as part of a whole-system job in San Anselmo adds $150-$300 to the base price; standalone vent and register cleaning runs $250-$450 depending on count and accessibility. We pull each register, clean the boot and first few feet of duct behind it, and replace everything without scratching your floors or walls.
Register and Grille Restoration
Painted-shut registers are common in San Anselmo’s Victorian and Craftsman homes. We free them carefully, clean the original metal or replace with matched reproductions if requested, and never force anything that would damage a century-old finish.
Pet Hair and Allergen Removal
Families with dogs and cats in San Anselmo’s hillside neighborhoods see rapid buildup in return vents near floor level. We use compressed air and mechanical agitation, not just vacuum suction, to dislodge embedded hair before extraction. Quieter tools during nap hours, always.
Trusted Brands We Service in San Anselmo
We clean and maintain systems with components from Honeywell, Aprilaire, and Abatement Technologies, and we stock common filters, media, and access panels for San Anselmo customers so we’re not ordering parts while your system sits open. Our Rotobrush and Nikro cleaning equipment is professional-grade, not rental-shop level, and our technicians train on it annually. If your San Anselmo home has an older Aprilaire humidifier tied into the duct trunk or a Honeywell media air cleaner on the return, we know how to remove, clean, and reinstall without breaking the seal or voiding any remaining warranty.
Common Air Duct Cleaning Problems We See in San Anselmo Homes
- Flood-deposited mold in low-lying crawl-space ducts. San Anselmo’s 2005 and 2006 creek floods pushed water into subfloor ductwork that many homeowners never had professionally treated. Standard cleaning agitates surface dust but leaves mold colonies intact in the damp metal trunks.
- Restricted equipment access in downtown apartment buildings. Shared HVAC and dryer vent systems in San Anselmo’s downtown multi-family buildings require coordination with building management and parking permits our crew arranges in advance, not after arriving.
- Fog-driven moisture accumulation in uninsulated metal ducts. The Ross Valley channels marine fog inland, keeping San Anselmo’s ambient humidity higher than inland Marin for weeks at a stretch. That moisture lingers in older uninsulated ductwork and binds dust into cake that simple suction won’t remove.
- Original 1930s duct layouts with no modern access panels. Pre-WWII San Anselmo homes often have continuous sheet-metal runs with no cleanouts. We cut access where needed, seal them properly after, and never leave gaps that would leak conditioned air into the crawl space.

FAQs About Air Duct Cleaning in San Anselmo
No. Standard agitation and vacuum cleaning will not eliminate mold colonies established in damp sheet-metal duct trunks over nearly two decades. We recommend video inspection first, then HEPA-contained source removal with antimicrobial treatment to the affected low-lying sections. Call (323) 918-4345 and mention the flood history when you schedule - we’ll build the right scope and quote it upfront.
We coordinate with building management for roof or basement equipment room access, arrange parking permits in advance, and use portable Nikro units that don’t require truck mounting. For shared dryer vent stacks, we clean the common stack from the roof or utility room, not just the unit-side segment. The quote covers this access planning - no surprise charges if it takes an extra trip to confirm logistics.
The Ross Valley funnels Pacific moisture deep inland, so San Anselmo stays foggy and humid while Novato burns off by mid-morning. That persistent dampness keeps dust bound to duct walls and supports mold spore viability year-round. Our cleaning protocol here includes longer agitation cycles and moisture assessment that drier-climate crews might skip.
Usually yes, though we assess crawl-space clearance during the estimate. Our Rotobrush portable units fit through 18-inch openings, and for tighter spaces we use flexible shaft tools and remote camera guidance. We’ve cleaned ducts under homes in the Sleepy Hollow neighborhood where the crawl space was barely shoulder-height. If we genuinely can’t reach a segment, we’ll tell you before we start, not after we’ve taken your money.
Yes. Our source removal methodology, negative-pressure containment, and post-cleaning verification align with NADCA ACR guidelines. For San Anselmo’s flood-affected homes, we exceed the standard by including moisture mapping and antimicrobial treatment in scopes where visual inspection indicates need. We document this with before-and-after photos, included with every job.
