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.

Why Morton’s Air Duct Cleaning Is Cotati’s Preferred Air Duct Cleaning Company
Cotati homeowners call us back because we treat their houses like the homes they are, not job sites. Our technicians wear shoe covers and lay drop cloths before stepping past the threshold, work quietly around nap schedules, and choose pet-safe products where the option exists. Every visit follows the Cedarwell Care Promise, a system our independently owned company chose to uphold, not a corporate mandate.
Our local reputation in Cotati comes from two decades of showing up on time, honoring the written price we gave on the phone, and leaving photo proof of the clean-up before we drive away. We’ve worked in the ranch homes off East Cotati Avenue, the duplexes near La Plaza Park, and the student rentals along Old Redwood Highway. That familiarity means we know which crawlspaces flood seasonally and which attics bake in summer heat.
A live person answers our phone 24/7. Not a chatbot, not a callback queue. When you’re trying to schedule around work and school pickups, that matters.
Ductwork Cleaning in Cotati
Ductwork Cleaning in Cotati means more than pushing a brush through visible vents. Our crews use Rotobrush agitation tools combined with negative-pressure HEPA collection to source-remove debris from every accessible section of your system, including the returns, supplies, and trunk lines that run through attics and crawlspaces in Cotati’s 1960s-1980s ranch homes. A typical whole-home Ductwork Cleaning in Cotati runs $350-$550 for single-story homes under 2,500 square feet, with larger homes or systems requiring additional access points running toward the upper end.
What We Find in Older Cotati Systems
Original sheet-metal ducts in Cotati’s post-incorporation housing stock often develop disconnected or crushed runs from decades of deferred maintenance, especially in rental properties where HVAC upkeep has been spotty. Debris bypasses the registers entirely, collecting in crawlspace low points or attic trunk lines where homeowners never see it. We locate these breaks with video inspection, then clean and reconnect the runs with mastic sealant so airflow reaches the rooms it was meant to serve.
Moisture-Driven Contamination Near the Laguna
On the western side of Cotati, near the Laguna de Santa Rosa floodplain, we regularly find flex-duct sections showing mold colonization even in systems less than 15 years old. The seasonally high water table keeps ground-level runs damp, and Petaluma Gap fog drives humidity into attic spaces that drier inland homes don’t experience. Our Nikro HEPA-negative-air machines contain this debris during removal rather than spreading it through your home.
Air Duct Inspection in Cotati
Air Duct Inspection in Cotati gives homeowners a clear picture of what’s happening inside walls and crawlspaces they can’t see into themselves. We run color video cameras through accessible duct runs, documenting disconnected sections, mold growth, debris accumulation, and structural damage specific to Cotati’s aging housing stock and moisture environment. A typical Air Duct Inspection in Cotati costs $150-$250 as a standalone service, or it’s included at no extra charge when bundled with a full cleaning.
When Cotati Homeowners Need an Inspection First
If you’ve noticed uneven heating, musty odors when the system kicks on, or higher-than-expected energy bills in your Cotati home, an inspection often reveals the real problem before you spend money on cleaning that won’t fix it. We’ve found crushed flex duct in crawlspaces off West Sierra Avenue and disconnected returns in attics near Sonoma State that explained years of comfort complaints. The video footage belongs to you; we explain what we’re seeing and what it would take to correct it.
Pre-Purchase Inspections for Cotati Rentals
Cotati’s concentration of student and workforce rentals means many buyers inherit HVAC systems with unknown maintenance histories. A video inspection before closing documents existing conditions and often identifies deferred maintenance the seller should address. We provide written findings with timestamped footage you can share with your realtor or property manager.
Trusted Brands We Service in Cotati
Our crews arrive with professional-grade equipment from Rotobrush, Nikro, Aprilaire, and Abatement Technologies, not rental-shop gear that loses suction halfway through a job. We stock common replacement parts for Honeywell and Aprilaire media filters used in many Cotati homes, which means faster turnaround when your system needs more than cleaning. For sealing work, we use Guardsman-rated mastic and metal-backed tape rated for the temperature swings your attic ducts experience through Cotati’s mild winters and warm, fog-cooled summers. Every tool choice traces back to the same question Paul Adeyemi asks: would we want this equipment running in our own home while our kids are in the next room?
Common Air Duct Cleaning Problems We See in Cotati Homes
- Mold in young flex duct near the Laguna de Santa Rosa. The seasonally high water table and persistent Petaluma Gap humidity create conditions we don’t see in drier Rohnert Park neighborhoods just east. Even 12-year-old systems show black colonization inside the liner when ground-level runs sit in damp crawlspaces.
- Disconnected sheet-metal runs in 1970s ranch homes. Decades of thermal expansion, rodent activity, and deferred maintenance separate original duct sections, dumping conditioned air into attics and crawlspaces instead of bedrooms. Homeowners wonder why one room never heats properly.
- Crushed flex duct from prior service work or storage. In Cotati’s smaller multi-family rentals, maintenance workers or tenants sometimes compress duct runs to gain crawlspace access or storage space, restricting airflow and straining the blower motor.
- Condensation during shoulder seasons. Cotati’s fog-driven humidity keeps duct surfaces damp in spring and fall when HVAC systems run infrequently. Without adequate insulation or regular airflow, this moisture feeds mold and mildew that a simple surface cleaning won’t reach.
Pricing for Air Duct Cleaning in Cotati, CA
Whole-home air duct cleaning in Cotati typically runs $350-$650 depending on system size, accessibility, and whether we find conditions requiring additional work like mold remediation or duct sealing. A single-story ranch with accessible attic and crawlspace points usually falls in the $350-$450 range. Two-story homes, systems with hard-to-reach trunk lines, or properties requiring extensive reconnection work may reach $550-$650.
We do not quote per-vent prices. That model invites bait-and-switch tactics we’ve all heard about, low teaser rates that balloon once the crew is in your driveway. At Morton’s, you get one flat price per system, agreed in writing before any work starts. No exceptions. Estimates are free, and we encourage you to compare our written quote to any other you receive.
Video inspection alone runs $150-$250; duct sealing or reconnection work discovered during cleaning is quoted separately before proceeding. Call (323) 918-4345 for your specific estimate.

FAQs About Air Duct Cleaning in Cotati
Cotati sits directly in the Petaluma Gap wind corridor, which funnels marine fog and moisture-laden air from Bodega Bay into the city far more intensely than inland Santa Rosa receives. This persistent humidity, combined with the seasonally high water table near the Laguna de Santa Rosa floodplain, keeps ground-level and attic duct surfaces damp enough for mold colonization even in systems less than 15 years old. Santa Rosa’s slightly drier, more protected climate doesn’t produce the same condensation patterns. If you live on Cotati’s western side and smell mustiness when your HVAC kicks on, an inspection with video documentation will show you exactly what’s happening inside. Call (323) 918-4345 to schedule.
Original sheet-metal ducts can almost always be cleaned and reconnected; replacement is only necessary when the metal itself has corroded through or been structurally damaged. In Cotati’s 1960s-1980s ranch homes, we more commonly find disconnected runs, failed seams, and debris accumulation that professional agitation cleaning and mastic sealing can fully correct. We inspect with video before recommending any replacement, and you’ll see the footage yourself. Most Cotati homeowners with original duct systems spend $350-$550 on cleaning and reconnection rather than thousands on full replacement.
Agricultural particulates from the dairy farms and pasturelands surrounding Cotati introduce organic dust that accumulates in duct systems over time, particularly in homes with older or poorly sealed returns. This material differs from ordinary household dust; it carries higher organic content that can support microbial growth when combined with Cotati’s humidity. Our HEPA-negative-air cleaning removes this debris source rather than redistributing it, and sealing disconnected returns afterward prevents new infiltration. If you live near the agricultural edges of town and notice dust returning quickly after cleaning, your system likely has intake leaks we can locate and seal.
Homes west of Highway 116 and near the Laguna de Santa Rosa floodplain should prioritize inspection and cleaning before the fall rainy season, when the water table rises and humidity peaks. We typically recommend late summer or early fall scheduling so any moisture-driven mold or debris issues are addressed before conditions worsen. If you’ve already noticed musty odors, uneven airflow, or visible mold around registers, don’t wait. Call (323) 918-4345 and we’ll get you on the calendar.
Persistent humidity forces your blower motor to work harder to push air through damp, debris-laden ducts, increasing amp draw and shortening component life. In Cotati’s climate, we regularly find blower wheels caked with dust that has absorbed moisture and hardened into a mat, throwing the wheel out of balance. The air handler itself can develop corrosion on electrical components when humid return air bypasses filtration through disconnected duct sections. Cleaning the full system, reconnecting separated runs, and sealing leaks reduces this strain and often improves static pressure readings noticeably.
