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.
Fast, Reliable Air Duct Cleaning Across Sonoma
Air duct cleaning in Sonoma typically runs $400 – $800 for a full residential system, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve Sonoma from our San Francisco Bay Area dispatch office. If you’re noticing weak airflow, dust that returns within days of cleaning, or a persistent smoke smell during fire season, your ductwork needs more than a surface wipe. Call us at (361) 326-5060 for a written estimate before any work begins.
Sonoma’s mix of historic Plaza homes, vineyard-adjacent properties, and mid-century ranches creates duct problems you won’t find in textbook training. We’ve cleaned systems off East Napa Street, along Broadway, and in newer developments near the Sonoma Golf Club. Each neighborhood presents different duct materials, different failure modes, and different solutions. That’s why we start every job with a video inspection, not assumptions.
Why Hollis Air Duct Cleaning Is Sonoma’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004, and our Air Duct Cleaning team has worked on enough Sonoma homes to know the patterns. Around the Plaza, we expect redwood-framed structures with retrofitted ductwork running through crawlspaces that were never sealed for HVAC. Near the vineyards, we anticipate harvest-season buildup that standard equipment won’t touch. This local knowledge saves our customers time and money because we diagnose correctly the first time.
Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing before touching equipment, complete the job by the book, and leave the site clean. Every job carries our 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule.
Commercial Air Duct Cleaning in Sonoma
Commercial Air Duct Cleaning in Sonoma addresses the larger, more complex systems found in wineries, tasting rooms, restaurants along the Plaza, and retail spaces on Broadway. These buildings often run rooftop units with extensive duct networks that collect grape dust, wildfire ash, and cooking particulates. A typical commercial job in Sonoma ranges from $1,200 – $3,500 depending on system size and accessibility, with written pricing provided before work starts.
Winery and Hospitality Systems
Sonoma’s tasting rooms and event spaces see seasonal spikes in occupancy that load ducts with skin cells, pollen, and outdoor contaminants. We use Nikro negative-air machines to contain debris during cleaning, protecting your product and your guests. Rotary brush agitation from Rotobrush equipment dislodges buildup that compressed-air methods leave behind.
Restaurant and Kitchen Exhaust Integration
Many Sonoma restaurants combine general HVAC ductwork with kitchen exhaust systems. We inspect the intersection points where grease particles can migrate into supply ducts, creating fire hazards and odor problems. Our crew documents these conditions with video and provides a written scope before cleaning begins.
Air Duct Cleaning Services in Sonoma
Air Duct Cleaning Services in Sonoma cover residential systems from historic homes near the Plaza to newer construction on the east side. A typical full-system residential cleaning runs $400 – $800, with video inspection included. We don’t quote per-vent pricing because that’s where the bait-and-switch starts. One flat price per system, agreed in writing, before we touch anything.
Source Removal with Negative Pressure
Our standard method uses a Nikro negative-air machine connected to your trunk line. This creates suction throughout the system while Rotobrush rotary tools agitate debris at each branch. Debris travels to our HEPA-filtered collection unit, not your living room. We explain every step while we work.

Duct Sealing and Reconnection
In Sonoma’s older homes, we often find that “dirty ducts” are actually disconnected or crushed runs pulling crawlspace air into your supply. We reconnect these with mechanical fasteners and seal with mastic, not tape. This is the real fix for weak airflow and persistent dust, and it’s included in our scope when we find it.

Trusted Brands We Service in Sonoma
We stock filtration products from Honeywell, Aprilaire, and Guardsman for Sonoma customers, with same-day availability on common sizes. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use in hospitals and schools. When we recommend a filter upgrade after cleaning, we install what fits your existing cabinet, not a proprietary part that locks you into future service. For homes with Abatement Technologies filtration cabinets, we carry the correct replacement media and can show you the MERV rating difference on the spot.
Common Air Duct Cleaning Problems We See in Sonoma Homes
- Crushed and disconnected branch runs in historic homes. On a 1908 redwood-framed home off East Napa Street, our tech ran camera inspection through the air handler and found two crushed runs under the floor and a disconnected return that was pulling crawlspace air into the supply and return ducts. We performed source removal with agitation tools under negative pressure, reconnected and sealed the failed runs, and installed high-MERV filtration matched to the homeowner’s Honeywell cabinet. The homeowner reported immediate airflow improvement at the registers and far less dust settling on furniture within a week.
- Grape must and harvest dust coating. During harvest season (August – October), local technicians report a noticeable increase in calls from residents near vineyards due to a fine, sticky film of grape must and dust coating return vents and ducts. Standard shop-vac cleaning misses this without HEPA filtration and dedicated agitation tools. We see this pattern along Arnold Drive and in homes backing up to vineyard properties.
- Moisture and mold in east-side flexible ducting. Mid-century ranches and newer builds on Sonoma’s east side often use flexible ducting in poorly insulated attics. Winter moisture intrusion creates mold colonies that cleaning alone won’t fix. We identify these conditions with video inspection, then clean, seal, and recommend insulation corrections.
- Wildfire ash infiltration throughout the system. Sonoma’s position between the Mayacamas and Sonoma Mountains means recurring fire seasons fill ducts with fine ash particles. These pass through standard filters and embed in duct interiors, creating respiratory irritants and persistent smoke odor. Our HEPA-captured cleaning removes this material, and we upgrade filtration to prevent rapid reaccumulation.
Pricing for Air Duct Cleaning in Sonoma, CA
Here’s what honest pricing looks like in Sonoma’s market:
- Full residential system cleaning: $400 – $800

FAQs About Air Duct Cleaning in Sonoma
Every 2 – 3 years for most Sonoma homes, and annually if you’re in a heavy fire-smoke zone or within a quarter-mile of active vineyards during harvest. The combination of fine ash particles and sticky grape must accelerates buildup beyond what inland Bay Area homes experience. Call (361) 326-5060 for a free inspection if you’re unsure where your system stands.
Probably not on its own. Because Sonoma’s historic homes around the Plaza were framed in redwood and fir and ducted after the fact, many systems here run branch runs through unsealed crawlspaces and attics, so the real problem is often disconnected or crushed flexible runs rather than dirty duct interiors, confirmed by camera inspection, not guesswork. We clean what’s dirty and seal what’s broken. The full fix typically runs $600 – $1,200.
Grape must creates a sticky, organic film that traps additional dust and resists standard vacuum methods. It can be removed with rotary brush agitation under negative pressure combined with HEPA filtration, but not with a shop vac or compressed-air wand. We see this most often August through October in vineyard-adjacent properties.
Yes, though for different reasons. Newer builds often have flexible ducting that can harbor mold after winter moisture intrusion, and tighter construction means indoor pollutants recirculate more concentrated. We inspect with video before recommending cleaning, and we often find that sealing duct joints improves efficiency more than cleaning alone.
Yes, significantly, if the odor is coming from ash particulate lodged in duct interiors and on the evaporator coil. Cleaning removes this material, and upgrading to a higher-MERV filter helps prevent rapid reaccumulation. Persistent smoke smell may also indicate filter bypass or leaks in the return path, which we identify and seal during service.
