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 Lucas Valley-Marinwood, CA
If you’re searching for an air duct cleaning company in Lucas Valley-Marinwood, you’ll find pricing here typically runs from $425 to $875 for a full-system cleaning on a single-family home, with dryer vent cleaning adding $140 to $210. The work in Lucas Valley-Marinwood is shaped by a climate pattern that keeps ducts damp well past dawn, and by housing stock built in the 1950s through 1970s that often still carries its original ductwork. That combination means the job here involves more than vacuuming out a few vents. Call (980) 447-2498 and we’ll give you a written price before any work starts.
Why Lucas Valley-Marinwood Homes Are Different
Lucas Valley-Marinwood sits in an inland valley that funnels and traps the marine layer rolling in from the coast. Night after night, condensation forms on cool duct surfaces; day after day, the valley sun bakes it dry again. That repeated cycle of nighttime condensation and daytime dryout is harder on duct interiors than the persistent dry air most of the Bay Area sees, and it’s a pattern neighboring flatter communities like San Rafael proper don’t experience at the same intensity. Fiberglass duct board, common in the original systems around here, absorbs that moisture, which causes the interior liner to delaminate and shed fibers into the airstream over time.
The Marinwood section’s post-WWII planned housing stock was built out heavily in the 1950s and 1960s. Many of those ranch-style and split-level homes still have their first-generation forced-air systems, now 60+ years old, running through unconditioned crawlspaces or attics where humidity swings are most extreme. Lucas Valley’s custom and semi-custom homes from the 1960s through 1980s add a second wave of aging ductwork with the same vulnerability. Technicians working Marinwood’s tract streets also regularly find rodent nesting packed into floor-register boot boxes, driven by the proximity of Lucas Valley Open Space Preserve and the surrounding oak-and-grassland hillsides that push roof rats and mice into the older slab-on-grade and raised-foundation homes seasonally. That’s a wildlife-intrusion pattern far less common just a few miles south in flatter, more developed San Rafael neighborhoods.
Our Main Lucas Valley-Marinwood Services
Three services cover nearly every call we take in Lucas Valley-Marinwood: air duct cleaning, dryer vent cleaning, and air duct repair. Each has its own page with local pricing and specifics, linked below.
Air Duct Cleaning in Lucas Valley-Marinwood
Full-system air duct cleaning in Lucas Valley-Marinwood uses negative-pressure extraction: we seal each register and pull a powerful vacuum through the main trunk line while agitating the interior walls to release years of buildup. In this valley, that buildup is often a mix of delaminated fiberglass liner particles, dust, pollen, and condensation-compacted debris that’s hardened against the duct walls. The moisture cycle makes some of this material stick, which is why basic surface vacuuming doesn’t get it out. Read more about Air Duct Cleaning in Lucas Valley-Marinwood.
Dryer Vent Cleaning in Lucas Valley-Marinwood
Dryer vents in Lucas Valley-Marinwood often exit through the roof or run long horizontal stretches through unconditioned attic space, where the marine layer’s humidity turns lint sticky before it can fully exit. We clean the full run from the dryer’s lint trap bypass to the exterior termination cap, removing the packed lint that slows drying and creates a fire risk. A clogged vent also forces your dryer to work harder, which shows up in longer cycle times. See Dryer Vent Cleaning in Lucas Valley-Marinwood for local pricing.
Air Duct Repair in Lucas Valley-Marinwood
Older Lucas Valley-Marinwood homes frequently need duct repair work that goes beyond cleaning: crushed trunk lines under the slab, disconnected branch runs in crawlspaces, rodent-chewed flex duct, and corroded register boots. We assess the damage, show you what’s there with photos, and give a written repair price before we touch anything. Every repair carries a written guarantee, and if a covered repair fails within the warranty period, we return at no charge. See Air Duct Repair in Lucas Valley-Marinwood.

What Lucas Valley-Marinwood Customers Say
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
