Air Duct Cleaning in Sonoma, CA
Air duct cleaning in Sonoma typically costs $350-$650 for a standard single-system home, with most jobs completed in one visit. Our crews serve Sonoma from our San Francisco Bay Area office, and we know the valley’s specific duct conditions - from sulfur-laced vineyard dust to post-wildfire particulate - that standard cleaning protocols miss. Call (855) 401-6006 to speak with a live person, day or night, and we’ll give you an upfront price before any work begins.
Why Sonoma Homes Are Different
Sonoma sits at the floor of the Valley of the Moon, and that geography shapes everything about your ducts. Marine fog rolls in from San Pablo Bay most nights, pooling in the valley until midday sun burns it off. Those daily humidity swings create condensation inside crawl-space and attic ductwork, especially in the flex-duct runs common to ranch homes built between the 1950s and 1970s. Where moisture collects and air stagnates, mold colonizes - we’ve opened duct boots in Sonoma crawl spaces to find active growth that the homeowner never smelled because the system had been “working fine.” The valley topography that traps fog also concentrates wildfire smoke. Homes that ran HVAC during the October 2017 Nuns Fire, which burned directly in the Mayacamas Mountains above the city, likely have smoke particulate and combustion ash still embedded in their duct systems. This isn’t theoretical - we camera-inspect ducts in Sonoma and find the telltale gray residue that ordinary household dust doesn’t match.
Air Duct Cleaning in Sonoma
Our Air Duct Cleaning service addresses the contamination that Sonoma’s unique conditions create: vineyard sulfur residue, wildfire ash, and mold from marine fog humidity. Every job starts with camera inspection so you see exactly what’s in your ducts before we begin.
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 retrofitted decades after construction. That means tight access, odd angles, and flex-duct runs that have settled and sagged over forty or fifty years. 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.
Commercial Duct Cleaning
Wineries, tasting rooms, and hospitality properties along Highway 12 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. Commercial jobs typically start at $800 and scale with system complexity.
How often should Sonoma homeowners clean their air ducts?
Most Sonoma homes benefit from professional duct cleaning every 3-5 years, but 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 or noticed reduced airflow, don’t wait for the calendar. Call (855) 401-6006 and we’ll tell you what we see.
Dryer Vent Cleaning in Sonoma
Dryer vent cleaning in Sonoma typically runs $149-$289 for standard residential jobs, with longer acreage vent runs reaching $320-$450. Most appointments are completed in a single visit, and our technicians carry equipment to handle rural properties with extended ductwork without scheduling a return trip. Our Dryer Vent Cleaning service addresses the specific hazards that Sonoma’s vineyard proximity creates.
Vent Cleaning & Lint Removal
Our vent cleaning process uses Rotobrush mechanical agitation paired with Nikro HEPA-contained vacuum extraction. For Sonoma’s longer rural runs, we often need to access and clean from both ends - the dryer connection and the exterior termination - to fully clear accumulated material. Homes near active vineyards require extra passes because elemental sulfur dust binds to lint differently than household fibers, creating dense, almost tar-like deposits. Standard residential vent cleaning in Sonoma runs $149-$189; two-story or extended runs of 15-30 feet run $195-$289.
Why does my dryer smell like sulfur during harvest season?
Elemental sulfur from vineyard fungicide applications has entered your vent system and mixed with lint. During September-October harvest, mechanical harvesters run through the night on properties adjacent to residential streets in Sonoma, kicking up fine vineyard dust laced with residual sulfur - a genuine fire and air-quality hazard, not a cosmetic issue. Call (855) 401-6006 for a camera inspection and exact quote.
HVAC Cleaning in Sonoma
HVAC cleaning in Sonoma typically runs $280-$650 for a complete system service, and most jobs are finished in a single visit. If you’re smelling sulfur when the heat kicks on, or your airflow has dropped since last harvest season, the problem is likely in your evaporator coil or ductwork, not the filter. Our HVAC Cleaning service targets these Sonoma-specific failures.
Evaporator Coil Cleaning
The evaporator coil is where Sonoma’s vineyard dust does its worst damage. Fine particles laced with elemental sulfur from fungicide applications settle on the wet coil surface and harden into a yellowish, gritty layer that standard filters can’t stop. Using our Rotobrush system and custom coil treatment, we deep-clean the coil and air handler, restoring airflow and eliminating the acrid smell. Coil treatment bundled with full cleaning runs $120-$220.
Why does my HVAC smell like sulfur during harvest season?
The smell comes from elemental sulfur residue in vineyard dust that’s drawn into your system intake during September and October mechanical harvesting. This dust settles on your evaporator coil and in ductwork, then releases its odor when heated or cooled. We remove the residue with specialized coil treatment and agitation cleaning - call (855) 401-6006 for a free inspection and exact quote.
Duct Repair & Sealing in Sonoma
Most Sonoma duct repair jobs run $180-$650 and are finished in a single visit. Properties on the east side of town off Arnold Drive, the ranches along Sonoma Highway, and the older neighborhoods ringing the Plaza - they’re spread out, and arriving prepared matters. Our Duct Repair & Sealing technicians stock trucks for the full range of materials before leaving the shop.
Flex Duct Repair
Flex duct is common in Sonoma’s 1950s-1970s ranch homes, where central HVAC was retrofitted into crawl spaces after original construction. The daily humidity swings from marine fog cause the inner liner to sag, detach at the plenum, or collapse entirely. We repair with proper support strapping and mastic-sealed metal connections that survive these conditions. Flex duct repair in Sonoma runs $180-$420 per run.
Why do flex ducts in Sonoma’s crawl spaces fail more often?
Marine fog from San Pablo Bay pools nightly in the valley floor, creating daily humidity swings that condense on duct surfaces and degrade tape adhesives. Flex ducts in retrofitted 1950s-1970s ranch homes were often installed with minimal support strapping in cramped crawl spaces, so they sag, kink, and detach under this stress. We repair with proper support and mastic-sealed metal connections. Call (855) 401-6006 for an inspection.
Air Quality & Sanitizing in Sonoma
Air quality and sanitizing service in Sonoma typically costs $350-$850 for whole-home duct treatment, with most appointments completed in a single visit. We understand the specific contamination patterns that affect properties here - from vineyard sulfur residue to wildfire smoke embedded deep in older duct systems. Our Air Quality & Sanitizing service addresses what standard cleaning leaves behind.
Mold Treatment & Odor Removal
Sonoma’s daily fog cycle creates condensation inside attic and crawl-space flex ducts that older ranch homes weren’t designed to manage. We regularly find mold colonization in sagging runs above bedrooms in neighborhoods along Fifth Street West and MacArthur Street. Our mold treatment includes mechanical agitation with Rotobrush HEPA equipment, antimicrobial application from Abatement Technologies, and post-treatment verification. Mold treatment adds $200-$400 to a standard sanitizing job.
Does the sulfur from nearby vineyards actually get inside my ducts?
Yes. Elemental sulfur from agricultural fungicide applications becomes airborne during mechanical harvest and cultivation, enters through HVAC intakes, and bonds to coil and duct surfaces. We find it regularly in vineyard-adjacent Sonoma homes, and standard dust removal won’t eliminate the associated odor. Call (855) 401-6006 and we’ll show you on camera what’s actually in your system - estimates are free.

What Sonoma Customers Say
"The job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
- Jodi Ackerman"Booked online at nine at night, got a confirmation, a reminder, and a call when they were fifteen minutes out."
- Renee Fletcher"They ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
