Fast, Reliable Air Duct Cleaning Across Sonoma
Air duct cleaning in Sonoma typically runs $350-$850 for a full residential system, with most jobs completed in a single visit. We’re usually on-site within 24-48 hours of your call, and every job starts with a camera inspection so you see exactly what’s in your ducts before we begin.
Bellows has been sending crews up to Sonoma since the early 1990s. We know the difference between a 1920s craftsman near the Plaza with galvanized ductwork retrofitted through a crawl space and a 1970s ranch off Arnold Drive with sagging flex runs in the attic. That matters because the cleaning method, the access points, and what we’re likely to find are completely different. We’ve cleaned ducts on East Napa Street, in the Bungalow Heaven neighborhood, and along the vineyard-lined roads toward Schellville. When you call (855) 401-6006, you reach a live person at our office, any hour of the day. We’ll give you an honest price over the phone, and that’s the price on the invoice.
Why Bellows Air Duct & Vent Co. of California Is Sonoma’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Sonoma on showing up when we say and leaving the job done right. Our 90-Day Done Right Promise means if something isn’t right, we return at no charge. No paperwork to file, no argument.
Sonoma homeowners call us back because we don’t bait-and-switch. The price we quote is the price you pay.

That’s not a sales tactic; it’s how Roger Castañeda has run this company since 1984.
Our technicians are background-checked, uniformed, and trained on Rotobrush and Abatement Technologies equipment. Most jobs are finished in one visit. And when you call, a real person answers - not an app, not a voicemail tree.
Our Air Duct Cleaning Services in Sonoma
Residential Duct Cleaning
Sonoma’s housing stock demands a careful eye. The craftsman bungalows and Spanish Colonial homes near the historic Plaza often have original plaster walls with ductwork that was retrofitted decades after construction. That means tight access, odd angles, and flex-duct runs that have settled and sagged over forty or fifty years. Our residential cleans account for this - we don’t force equipment through fragile older runs, and we check for disconnection points where dust has been spilling into your crawl space or attic for years. A typical residential duct cleaning in Sonoma runs $350-$650 for a single-system home.
Commercial Duct Cleaning
Wineries, tasting rooms, and hospitality properties along Highway 12 and the Sonoma Plaza face a specific challenge: high visitor traffic pulling in outdoor particulate, combined with seasonal vineyard dust that loads HVAC filters faster than standard commercial schedules anticipate. We clean commercial duct systems in Sonoma with the same camera-verified approach, scheduling around your operating hours to avoid disrupting service. Commercial jobs typically start at $800 and scale with system complexity.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Sonoma, these lines often run through attics that bake in summer heat and collect marine fog moisture in winter. When we clean supply ducts, we’re removing the dust and debris that’s been accumulating at the register boots and in the trunk lines - the same buildup that reduces airflow and makes your HVAC system work harder than it should. Supply-only cleaning in Sonoma generally runs $250-$450.
Return Duct Cleaning
Return ducts are the intake side, and in Sonoma, they tell the real story. These are the lines pulling air from your home back to the air handler, and they’re where we find the heaviest buildup - especially in homes near working vineyards. On a Spanish Colonial home on East Napa Street near the Plaza, we found the return ducts coated with a gritty, sulfur-tinged dust from late-summer vineyard operations. Our Rotobrush system extracted nearly 4 pounds of fungicide-laced debris from the flex-duct runs in the crawl space. Return duct cleaning in Sonoma typically runs $200-$400, or it’s included in a full system clean.
Full System Cleaning
This is what most Sonoma homeowners need: complete cleaning of supply and return ducts, trunk lines, plenums, and the air handler cabinet. We recommend this for any home that hasn’t had professional duct cleaning in five or more years, and it’s essential for properties near the 2017 Nuns Fire burn zone or adjacent to active vineyards. Full system cleaning in Sonoma runs $500-$850 for most residential properties.
Video Inspection
Every Bellows job in Sonoma starts with this. We feed a camera through your ductwork and show you the condition before we begin. No guessing, no scare tactics - just a clear picture of what we’re dealing with. Video inspection is included at no extra charge with any cleaning service. If you want a standalone inspection without cleaning, it’s $150-$250.

Trusted Brands We Service in Sonoma
We clean and service ductwork connected to Aprilaire, Honeywell, and Abatement Technologies air quality systems - the same brands serious HVAC contractors specify for Sonoma’s climate. If your home has an Aprilaire media air cleaner or a Honeywell electronic air purifier, we know how to remove, clean, and reinstall those components without damaging the seals or electronics. We carry common replacement parts for these systems on our trucks, so most Sonoma customers don’t wait for a second visit. For specialized components, we source from suppliers in Petaluma and Napa with next-day turnaround.
Common Air Duct Cleaning Problems We See in Sonoma Homes
- Flex-duct sagging in retrofitted crawl spaces traps moisture and leads to mold growth. The daily fog cycle from San Pablo Bay creates condensation in crawl spaces that original installers never anticipated. Sagging low points become collection pools, and once mold establishes in the duct lining, it circulates spores every time your system runs.
- Sulfur residue from vineyard spray coats evaporator coils, reducing HVAC efficiency. During September and October harvest, mechanical harvesters run through the night on vineyard properties adjacent to residential streets. The fine dust they kick up carries residual elemental sulfur from fungicide applications. We find this gritty, pungent buildup coating evaporator coils and duct interiors in homes near working vineyards - a chemically distinct residue that ordinary household dusting won’t address.
- Smoke particulate from the 2017 Nuns Fire remains embedded in duct linings, requiring multiple cleaning passes. The fire burned directly in the Mayacamas Mountains above Sonoma, and homes that ran HVAC during those weeks pulled combustion ash deep into their systems. Standard single-pass cleaning doesn’t remove it. We’ve developed a multi-stage protocol for these properties, and we always start with video inspection to assess the depth of contamination.
- Older ranch homes with attic retrofits have disconnected trunk lines leaking conditioned air into unused spaces. The 1950s-1970s ranches in neighborhoods off Arnold Drive and Verano Avenue often have flex-duct trunks that have pulled free from plenums over decades of thermal expansion. You’re heating your attic, not your bedroom, and paying for the privilege.

What moves you within these ranges? System size, accessibility, and contamination level.

FAQs - Air Duct Cleaning in Sonoma
Yes, if your home is near working vineyards, your ducts likely contain sulfur-based fungicide residue that ordinary dust doesn’t. The elemental sulfur used in grape powdery mildew prevention becomes airborne during mechanical harvesting and settles in HVAC intakes as a gritty, chemically distinct buildup. Our Air Duct Cleaning team uses specialized agitation and extraction methods to remove this residue without spreading it through your home. Call (855) 401-6006 to schedule a free video inspection and we’ll show you exactly what’s in your system.
Mold is more common here than in drier inland areas due to the nightly marine fog that pools in the Sonoma Valley floor. The daily humidity swing - fog in, sun out - creates condensation inside crawl-space and attic ductwork, especially in flex-duct runs with sagging low points. If you smell mustiness when your system starts, or if family members have unexplained respiratory irritation, a camera inspection will tell us whether mold colonization is present. We recommend annual inspection for homes with crawl-space ductwork in Sonoma. Call (855) 401-6006 to book.
If your HVAC system was running during the October 2017 fire event, you should have your ducts professionally inspected. Smoke particulate and combustion ash from wildfires embed deeply in duct linings and standard filters don’t capture the ultrafine particles that penetrate deep into lung tissue. We’ve cleaned multiple Sonoma homes where post-fire duct contamination was still measurable years later. Our multi-stage cleaning protocol addresses this specifically, and we always start with video documentation. Call (855) 401-6006 for a free assessment.
Most Sonoma homes benefit from professional duct cleaning every 3-5 years, but several local factors can shorten that interval. Homes near active vineyards, properties with crawl-space ductwork in high-fog areas, and any home within the 2017 Nuns Fire burn zone should consider inspection every 2-3 years. If you’ve completed renovations, noticed reduced airflow, or seen visible dust at registers, don’t wait for the calendar. Call (855) 401-6006 and we’ll tell you whether your system needs attention now or can wait.
No - video inspection is included with every Bellows cleaning service at no additional charge. We believe you should see what we’re seeing before we start work, and verify the results after we’re done. Standalone inspections without cleaning run $150-$250. Either way, there’s no obligation to proceed with cleaning after you see the footage. Call (855) 401-6006 to schedule your free video inspection.
