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 Fairfax, CA
Full-system air duct cleaning in Fairfax typically runs $450 – $850 for a single-family home, with most jobs completed in one visit. What drives the price here isn’t standard household dust; it’s the fine wildfire smoke residue and redwood pollen that pour down the Ross Valley canyons and coat duct walls in homes from the flats to the hillside. We dispatch crews from our San Francisco Bay Area office, and when Fairfax homeowners call (361) 326-5060, we schedule a written estimate before any equipment crosses the threshold.
Why Fairfax Homes Are Different
Fairfax sits in a steep, wooded bowl of the Ross Valley, and that terrain shapes every duct cleaning we do here. Most homes were built between the 1920s and 1970s, small bungalows and postwar ranchers in the flats alongside newer custom builds climbing the hills. The older stock often still runs original rigid metal ductwork through tight attics and crawlspaces, while hillside remodels mix flex and rigid runs with connections that have loosened over decades of seasonal expansion.
The Mediterranean climate brings wet, mild winters and dry, warm summers, but the real pressure on duct systems comes from the Marin wildland-urban interface. Recurring wildfire smoke episodes push fine ash and char particles deep into ductwork, and strong seasonal winds drive redwood and fir pollen through every gap. After a major smoke event, we regularly find ducts that look clean at the register but are lined with sticky residue a standard vacuum won’t touch. Heavy winter rains can also push moisture into crawlspace ducts, creating conditions where mold takes hold. The combination means Fairfax jobs require rotary brush systems and HEPA filtration, not just a hose and a prayer.
Our Main Fairfax Services
These are the three services Fairfax homeowners call us about most often, each with its own Fairfax page and pricing.
Air Duct Cleaning in Fairfax
We clean supply and return ducts, registers, and the main trunk lines using Rotobrush rotary brush systems and negative-air machines from Nikro. In Fairfax, this means dislodging the compacted smoke residue and pollen that settle in the rigid metal ducts common to older ranch homes, then extracting it all with HEPA filtration so nothing recirculates. We also inspect for moisture damage in crawlspace runs, a frequent find after wet winters. Air Duct Cleaning in Fairfax covers full pricing and what the visit includes.
Dryer Vent Cleaning in Fairfax
Dryer vent blockages are a leading cause of house fires, and in Fairfax the problem is compounded by hillside homes with long, winding vent runs through multiple walls. We clear the full line from dryer to exterior termination, check airflow with a manometer, and verify the outside damper opens fully. Homes with original 1950s – 1970s vent routing often need extra attention at the elbows. Dryer Vent Cleaning in Fairfax has full details and pricing.
Duct Sealing in Fairfax
Leaky ducts waste conditioned air and pull in crawlspace dust and pollen. We seal accessible joints and connections with mastic and metal-backed tape, then pressure-test to confirm the improvement. In Fairfax, this matters especially in homes with mixed flex-and-rigid systems where previous work left gaps at the transitions, and in older bungalows where original sealing has dried and cracked. Duct Sealing in Fairfax explains the process and what results to expect.
