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 Cotati, CA
Air duct cleaning in Cotati runs between $450 and $900 for a complete single-system home, depending on the number of returns, the age of the ductwork, and how much moisture-driven buildup has settled inside. We’re Kestrel Air Duct Cleaning, and we’ve built our reputation on one thing Cotati homeowners keep telling us they can’t find anywhere else: a written price before we touch a single vent, and a 365-Day Done Right Promise that puts the guarantee in writing. If you’re dealing with ducts that haven’t been opened since the Tubbs Fire smoke settled in 2017, call us at (469) 972-3151.
Why Cotati Homes Are Different
Cotati sits directly in the path of marine air pouring through the Petaluma Gap, and that fact changes what we find inside ductwork here more than any other single variable. The same fog that keeps Cotati’s summer evenings cool also keeps crawlspace-level supply ducts damp, and in homes along the western edge near the Laguna de Santa Rosa, that ground-level moisture works its way into duct seams and supply plenums all year. Technicians on our Cotati jobs routinely find biological growth in supply plenums of homes with no visible water damage anywhere in the house. The wetlands keep the soil saturated, the saturated soil keeps crawlspaces humid, and the humid crawlspace air gets pulled into duct leaks. It’s a chain homeowners rarely see until a cleaning opens the system up.
Add to that the housing stock itself. Most of Cotati’s residential core went up in the 1960s and 1970s as a planned community, which means ranch-style homes with original fiberglass-lined sheet-metal ductwork now 40 to 60 years old. That fiberglass lining holds moisture and gives biological growth something to grip. Flex-duct sections in these systems have often deteriorated to the point where a basic cleaning job becomes a more involved project once we see what’s inside. And the wildfire years left their mark: the Tubbs Fire in 2017 and Kincade Fire in 2019 pushed fine smoke particulates deep into HVAC systems throughout Sonoma County, and in Cotati we still open older systems and find those particulates settled into the duct lining. The work here is rarely a quick pass. It’s a moisture problem, an age problem, and a smoke problem layered on top of each other.
Our Main Cotati Services
The two calls we get most from Cotati homeowners are for the same two problems: air ducts carrying years of moisture-fed buildup, and dryer vents packed with lint in homes where the vent run is long or aging. Each service has its own Cotati page below.
Air Duct Cleaning in Cotati
The homes we clean in Cotati were built in an era when duct sealing was an afterthought, and 50 years of Petaluma Gap humidity has worked its way into every seam. We run a Rotobrush rotary brush system through the supply and return lines to dislodge debris from the duct walls, then pull it out with a Nikro negative-pressure unit so nothing escapes back into the living space. An Abatement Technologies HEPA filter on the exhaust side keeps loosened particles out of the air you’re breathing during the job. Cotati homes near the Laguna de Santa Rosa often need extra attention in the supply plenum, where wetland moisture concentrates. See Air Duct Cleaning in Cotati for full pricing on this service.
Dryer Vent Cleaning in Cotati
Cotati’s ranch-style homes often put the laundry room on an exterior wall, but the vent run itself can be surprising: some of these 1960s layouts run the dryer vent up through the attic before it exits the roof, and a long vertical run collects lint faster than a short horizontal one. We clean the full run from the dryer connection to the exterior termination, not just the first few feet behind the appliance. In homes where the vent passes through a damp crawlspace near the Laguna de Santa Rosa, we check the pipe itself for moisture-related deterioration while we’re in there. Full detail is on Dryer Vent Cleaning in Cotati.

FAQs About Air Duct Cleaning Company in Cotati
We schedule Cotati jobs on a defined arrival window, and the window is given to you in writing when you book. We don’t promise same-day service, because most Cotati homes need a full-system cleaning that’s best done with proper scheduling rather than a rushed slot. Call (469) 972-3151 and we’ll give you the next available window.
No permits are required for air duct or dryer vent cleaning in Cotati. If you’re in an HOA with rules about roof or exterior vent access, we handle that on the scheduling side and will note any access constraints on the written quote before work starts.
If the cleaning falls short within 365 days – a supply plenum regrows biological buildup, a dryer vent re-clogs, or any part of the work we did fails – we return and make it right at no charge. It’s written on every job, not a verbal courtesy. You don’t need to argue; you point to the document.
If your Cotati ducts haven’t been opened in years, or you’re noticing the musty smell that comes back a week after you run the AC, call us at (469) 972-3151 for a free estimate. We’ll give you a written price before any work starts, show up in the window we gave you, and stand behind the result in writing.

What Cotati Customers Say
"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
