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.

AfterFast, Reliable Air Duct Cleaning Across Sonoma
Air duct cleaning in Sonoma typically costs between $425 and $1,100 for a full system, depending on home size, duct configuration, and how much has accumulated inside the runs. We serve the entire Sonoma Valley, from the historic streets around Sonoma Plaza to the vineyard-adjacent homes off Arnold Drive and the newer subdivisions near Maxwell Farms Regional Park. Call (980) 447-2498 for a written quote before any work begins.
If you live in Sonoma, you already know the air here carries things most Bay Area cities don’t. Sulfur from vineyard spraying. Ash from fires that burned through the valley. Morning fog that rolls in through the Petaluma Gap and leaves moisture inside older ductwork. Our Air Duct Cleaning team deals with that specific combination every week, and we’ll tell you exactly what’s in your ducts before we touch them.
Why Linden Air Duct Cleaning Is Sonoma’s Preferred Air Duct Cleaning Company
Sonoma homeowners call us because we do something most duct cleaners in the North Bay skip: we actually inspect the system before quoting. A camera goes into the return and supply runs. You see what we see. The price we write down is the price you pay, and the tech who shows up at your door is the same person whose name and photo you received before the visit. No subcontracted strangers, no van full of mystery upcharges.
Every Linden technician is background-checked, identity-verified, and photo-badged under the Threshold Standard, which has been our operating discipline since 2004. That matters on a quiet street off Broadway where someone is home alone with two kids, or in an older neighborhood near Sebastiani Theatre where a homeowner in her seventies wants to know exactly who is walking up the drive. The tech shows a photo ID badge at the door. Every time. Not sometimes.
We also answer the phone with a live person whenever you call. That’s 24 hours a day, seven days a week. If you call at 6:30 a.m. because your furnace kicked on and blew a struck-match smell through the house, a real human picks up at (980) 447-2498.
Ductwork Cleaning in Sonoma
Ductwork Cleaning in Sonoma is a different job than it is in Petaluma, Novato, or any inland city, because the dust inside local ducts is not standard household lint. Homes on the valley floor sit inside active vineyard spray blocks. From spring through harvest, elemental sulfur fungicide drifts across the valley, and a meaningful portion of it gets pulled into return-air runs. Combine that with ash from the Nuns Fire and Glass Fire, and you get a pale, chalky, slightly acrid material bonded to duct walls. A basic brush-and-shop-vac job stirs it up. A proper negative-pressure extraction captures it through HEPA filtration before it re-enters your living space. That’s the job we do.
Source Removal, Not Surface Dusting
We set negative pressure at the air handler with a Rotobrush or Nikro system, then run agitation tools through every supply and return run. The debris gets pulled out of the house, not recirculated. In Sonoma’s retrofitted Victorians, that also means opening runs that haven’t been accessed since the HVAC was added decades after the house was built.
What a Real Clean Does for Sulfur and Ash
Removing the sulfur-and-ash residue is mechanical work. It requires agitation, negative pressure, and HEPA capture. It is not something a fogging sanitizer can accomplish, and we’ll explain that in plain terms before you spend a dollar. We’ll also say plainly when a home does not need the full treatment, because sometimes a 1,200-square-foot ranch off East Spain Street just has normal dust and a full clean would be overkill.
Air Duct Inspection in Sonoma
Air Duct Inspection in Sonoma is the step most homeowners skip, and it’s the step that matters most in this town. A camera inspection tells you whether your ducts are carrying years of sulfur residue and wildfire ash, whether the retrofitted runs in your pre-1950s home are leaking at unsealed joints, and whether your blower motor is straining against a filter that’s been overwhelmed. We perform this with professional camera reels from Nikro, not with a flashlight and a guess.
Camera Before Quote
Before we quote a cleaning, we send a camera into the return and supply sides. In Sonoma’s older balloon-frame homes, the duct routing is often irregular – elbows in odd places, transitions that were improvised during retrofit, debris pockets behind original lath walls. You deserve to see those conditions. So do we, because the quote depends on them.
Inspection for Retrofitted Victorians
The historic core around Sonoma Plaza is full of Victorian and early 20th-century homes where central HVAC was added decades after original construction. Those runs follow paths no modern builder would choose. An inspection is how we identify leak points, collapsed sections, and debris accumulation before any cleaning quote is written. Skipping this step on that housing stock is how homeowners end up with a cheap cleaning that misses half the problem.
Trusted Brands We Service in Sonoma
We work on systems from Trane, Carrier, Lennox, Rheem, Goodman, and York, and we install air-quality products from Aprilaire, Abatement Technologies, and Guardsman when a Sonoma home needs better filtration for post-fire particulate or sulfur-season air. Because so many homes in the valley have systems that were retrofitted or are running on older equipment, we keep common replacement parts and sealants on the truck. The goal is that when you need a repair after an inspection, the fix happens the same day, not after a week of waiting on a part.
Common Air Duct Cleaning Problems We See in Sonoma Homes
- Sulfur residue from vineyard spraying: Homes within a half-mile of active vineyard blocks on the valley floor routinely show a pale, chalky film in return-air ducts during and after spray season. Homeowners describe the smell as a faint struck-match odor when the furnace first runs each fall. Left alone, that residue corrodes uncoated galvanized sheet metal over time.
- Wildfire ash from the Nuns and Glass Fires: Fires that burned directly through Sonoma Valley in 2017 and 2020 left fine charred particulate that penetrated homes through every unsealed gap. That ash settles inside ducts and stays there, re-entering living spaces whenever the system cycles.
- Marine-layer humidity spikes: Morning fog from the Petaluma Gap raises humidity inside older ducts overnight, then warm afternoons dry them out again. That cycle leaves mold spores and mildew residue baked onto duct walls. A fogging sanitizer makes that worse by wetting the residue. Source removal plus sealing is the only fix that lasts.
- Leaky retrofitted runs in older homes: In balloon-frame Victorians and early 20th-century houses around Sonoma Plaza, retrofitted ducts were pushed through odd cavities and seldom sealed properly. Every unsealed joint pulls attic air, crawlspace dust, and whatever else is in the wall cavity directly into your supply air.

FAQs About Air Duct Cleaning in Sonoma
That odor is the signature of elemental sulfur residue inside your ducts. During vineyard spray season, sulfur fungicide drifts across the valley floor and gets pulled into return-air runs. It settles as a pale, chalky film. When you fire up the furnace for the first time in fall, the heat releases that sulfur smell. The fix is source removal: a mechanical cleaning with negative pressure and HEPA capture that pulls the residue out, not a spray that masks it. Call (980) 447-2498 and we’ll walk through what your system likely looks like.
Generally yes. Sacramento and San Jose homes accumulate standard household dust and pet dander. Sonoma homes on the valley floor also accumulate sulfur fungicide particulate and wildfire ash from fires that burned directly through the valley. That dual load is heavier and more chemically active. Homes within a half-mile of active vineyard blocks should be inspected every two to three years. Homes farther up the hillsides can often go five years. We’ll tell you which camp you’re in after a camera inspection.
No. Fogging wets whatever is already inside your ducts – including sulfur residue and ash – and that added moisture can feed microbial growth in Sonoma’s marine-layer humidity cycles. A real fix removes the source material first through negative-pressure extraction and HEPA capture, then addresses sealing and filtration so moisture doesn’t keep building up. We do not sell fogger-only packages because they don’t hold up in this climate. If mold is present, we’ll say so plainly and tell you what source removal plus sealing will cost.
Yes, and it should start with a camera inspection, not a flat-rate brush-and-vac. Retrofitted runs in balloon-frame Victorians follow irregular paths, often leak at unsealed joints, and collect debris in pockets behind original lath walls. A standard cleaning that never puts eyes on the inside of those runs is likely to miss the bulk of the problem. We set negative pressure at the air handler, run agitation tools through every accessible run, HEPA-vacuum, and then seal the leak points so the system doesn’t immediately re-contaminate itself.
Enough to see on camera. In homes within a half-mile of active vineyard blocks, we routinely find a pale, chalky film coating the return-air runs during and after spray season. After the 2017 and 2020 fires, we pulled return trunks that were packed with charred ash and sulfur-tinted dust. The amount that settles inside depends on how tight your ductwork is, how close you are to the spray blocks, and what kind of filtration your system runs. A camera inspection gives you the exact picture for your house, not a guess. Schedule one at (980) 447-2498.
