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 usually runs $380 – $680 for a standard single-system home, and most jobs take three to five hours from arrival to final walkthrough. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family (founded 2005), and we work in Cotati every week. Cotati’s mix of 1970s – 1990s tract homes and newer builds near the Sonoma State corridor means duct systems age differently from one street to the next, and the dry summer dust combined with coastal fog cycles pushes more fine particulate through returns than most homeowners expect. Call (737) 727-2314 for an exact quote.
Why Cotati Homes Are Different
Cotati sits in a microclimate pocket where warm inland air from the Santa Rosa Plain meets cooler coastal influence rolling up from Petaluma. That mix means moderate temperatures, but also a long dry season that loads attic duct runs with fine, talcum-like dust. In homes along Old Redwood Highway and the neighborhoods off East Cotati Avenue, we regularly see supply registers that blow visible dust within a year of the last cleaning, not because the system is damaged but because the exterior air is simply that particulate-heavy from May through October.
Housing stock matters too. The core of Cotati is 1970s and 1980s single-story ranchers, many with original flex-duct runs that have never been replaced. Flex duct from that era often has loose inner liners and separated joints at the boot collars, which means debris enters the airstream after the filter, not before it. Newer subdivisions near the Cotati grade and around Myrtle Avenue tend to have rigid trunk lines, which hold up better but collect dust differently. We adjust the cleaning method based on what the home actually has, not a generic checklist.
Our Main Cotati Services
Most Cotati homeowners call us about one of three things. Here’s how each works locally.
Dryer Vent Cleaning in Cotati
Cotati’s dry summers mean dryer lint stays loose, and long vent runs in single-story homes with the laundry room on an exterior wall still trap plenty of it at the first elbow. Laundry rooms off garages, common in Cotati’s 80s builds, often have vents that run 15 – 25 feet before exiting, and those need full brush-and-vacuum passes, not just a quick look from the outside. We use Rotobrush rods to break the lint free and a Nikro HEPA vacuum at the termination point so nothing blows back into the laundry space. Read the full breakdown on our Dryer Vent Cleaning in Cotati page.
Air Duct Cleaning in Cotati
Whole-system duct cleaning in Cotati typically means removing the register covers, cutting an access port into the supply and return plenums, brushing each run, and pulling the loosened material out under negative pressure. That last part matters: negative-pressure extraction means debris goes into the vacuum, not back into your living room. Attics here get hot, and that bakes dust onto duct interiors, so we run a longer dwell time on the brush heads than you’d need in a cooler climate. Details, including what to expect on the day, live on our Air Duct Cleaning in Cotati page.
HVAC Cleaning in Cotati
HVAC cleaning goes past the duct runs and into the air handler, blower wheel, evaporator coil, and the drain pan. Cotati’s dry-season dust gets drawn across the coil constantly, and once that coil is caked, your system works harder and your energy bill climbs. We clean the coil with a static-killing foam, pull the blower wheel to scrub each fin, and clear the drain line so condensate flows. Homes with original 1980s furnaces near the Cotati-Rohnert Park line often need this badly. The step-by-step is on our HVAC Cleaning in Cotati page.

FAQs About Air Duct Cleaning Company in Cotati
Most Cotati appointments are scheduled within a few days, and because our Bay Area dispatch runs crews on the Cotati-Rohnert Park-Petaluma corridor daily, we can often offer morning or afternoon windows that same week. You’ll get a live trackable arrival time through The Relay Standard before the technician shows up.
No. Duct cleaning is interior work on your own system and doesn’t require HOA approval anywhere we’re aware of in Cotati. If your attic access is through a shared wall or a condo setup, our techs work quietly and keep the entry area clean, but no permitting is involved. Call (737) 727-2314 if you want to confirm for your specific association.
That’s the norm, not the exception. Most Cotati homes we visit are on their first professional cleaning, especially the 1970s and 80s ranchers. The system usually needs a deeper first-pass clean and sometimes new filter media. We’ll show you before-and-after photos of your own ducts before you pay a thing.
