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
Cotati homes face a moisture problem most Sonoma County houses never see. The Petaluma Gap funnels coastal fog straight into town, and that humidity works its way into ductwork in ways you can smell before you ever see it. Most homes here are 1960s-to-1980s ranch builds still running original sheet-metal ducts, and between the damp air, the dairy dust from surrounding pasturelands, and decades of deferred maintenance in rental-heavy neighborhoods, a Cotati duct cleaning job rarely looks like one done ten miles inland. Call (323) 918-4345 and we’ll walk you through what your system needs, with a written price before anyone touches a register.
Why Cotati Homes Are Different
We’ve worked enough homes on both sides of Highway 101 to know Cotati’s ductwork carries a signature. The Petaluma Gap is a low break in the coastal mountains that pushes marine air from Bodega Bay directly over the city, keeping relative humidity persistently higher than in Santa Rosa or Sebastopol. That moisture condenses inside duct runs when HVAC systems sit idle during Cotati’s mild shoulder seasons, and it shows up as a fine gray film on registers, a musty note when the heat first kicks on in November, or visible mold colonization inside flex-duct sections. The pattern is most pronounced west of Old Redwood Highway, where the Laguna de Santa Rosa floodplain keeps water tables high enough to push ground moisture into crawlspace duct runs. On the Sonoma State University side of town, where student rentals turn over every few years, we regularly find 40-to-60-year-old systems that simply haven’t been opened in a decade. Add in the dairy farms ringing the city, and Cotati ducts collect a dust blend that carries agricultural particulates alongside ordinary household debris. None of this is a reason to panic. It’s just the local reality, and it means cleaning here takes longer and runs deeper than a quick vacuum pass.
Our Main Cotati Services
Two jobs account for nearly every call we take from Cotati homeowners. Each has its own dedicated page with local pricing, timelines, and what to expect on the day of the visit.
Air Duct Cleaning in Cotati
Cotati’s aging sheet-metal systems respond well to a thorough cleaning, but they need an approach that accounts for the Laguna-side moisture factor and the agricultural dust load. We inspect each duct run, run professional Rotobrush and Nikro equipment through the full system, and leave drop cloths and shoe covers in place from the front door to the furnace closet. You’ll see before-and-after photos of your own ducts, not a stock image. Air Duct Cleaning in Cotati has the full breakdown of what’s included and what a typical Cotati home costs.
Dryer Vent Cleaning in Cotati
Ranch homes built in the 1960s through the 1980s often route dryer vents through long, awkward runs that exit near crawlspace level, and the same moisture that affects ductwork also makes dryer lint cling harder inside vent walls. A clogged vent makes the dryer work harder and poses a real fire risk. We clean the full vent run, check the exterior cap, and verify airflow before we leave. Dryer Vent Cleaning in Cotati covers what to expect, including the written price you’ll receive before work begins.

Pricing for Air Duct Cleaning Company in Cotati, CA
Cotati jobs run on the higher end of Sonoma County ranges because of the extra time moisture-affected systems require. Here’s what you can expect before calling:
| Service | Typical range in Cotati |
|---|---|
| Whole-home air duct cleaning (single system) | $450-$750 |
| Air duct cleaning plus dryer vent cleaning | $550-$900 |
| Dryer vent cleaning only | $150-$250 |

| Crawlspace duct replacement | $1,500-$4,000 |
Homes west of Old Redwood Highway, near the Laguna floodplain, often run toward the upper end of these ranges because ground moisture means more sections need scrutiny and sometimes replacement.

What Cotati Customers Say
"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
- Shelby Dunham"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
