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 Boyes Hot Springs
Air duct cleaning in Boyes Hot Springs typically runs $350-$650 for a full residential system, and most jobs are scheduled within a week of your call. Our crews work the Sonoma Valley regularly, so we know the old resort-era cottages along Verano Avenue, the bungalows tucked behind Sonoma Highway, and the mid-century rentals near the historic bathhouse district. We dispatch from our San Francisco Bay Area office, and Boyes Hot Springs is a standard route for us, not a distant add-on. Call (469) 972-3151 and you’ll reach a live person who can book your arrival window and give you a written price before any work starts.
We’ve been cleaning ducts in this valley long enough to know that Boyes Hot Springs presents problems you won’t find in Santa Rosa or Petaluma. The geothermal ground beneath this community drives moisture into crawlspaces in a way that stains flex duct and breeds mold inside the runs. Combine that with wildfire ash from the 2017 Nuns Fire still lurking in older systems, plus the annual vineyard harvest dust that settles every September through November, and you’ve got a particulate load that standard surface cleaning won’t touch. Our Air Duct Cleaning team comes prepared for what we actually find here.
Why Kestrel Air Duct Cleaning Is Boyes Hot Springs’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Boyes Hot Springs on showing up in the window we promised and leaving the price where we wrote it. The Kingswell Way, our technician code, requires four things on every visit: say the price before touching a vent, arrive when we said we would, leave the job site cleaner than we found it, and put the guarantee in writing. No exceptions.
Our technicians are background-checked, uniformed, and trained on Rotobrush rotary brush systems for dislodging debris at the duct wall, Nikro negative-pressure units for pulling contaminants out, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. These aren’t box-store shop vacs. When we clean a system in Boyes Hot Springs, we document the work with before-and-after photos of your own ducts, not stock images.
The 365-Day Done Right Promise applies to every job we do in Boyes Hot Springs. If the work falls short within that year, we return and make it right at no charge. That’s documented in writing on every invoice, not a verbal assurance that disappears with the technician.
Calls are answered by a live person, 24/7. Not a voicemail queue. Not an automated system. A real conversation, any time of day.
Ductwork Cleaning in Boyes Hot Springs
Ductwork Cleaning in Boyes Hot Springs means more than running a brush through visible vents. Most homes here were built before 1960 as resort cottages or working-class rentals, with original or cheaply replaced flexible ductwork running through unconditioned crawlspaces directly above geothermal ground. That ground moisture wicks into the flex runs, leaving mineral-stained rings and mold colonies that a surface vacuum won’t remove. We typically find that a full residential system in Boyes Hot Springs runs $350-$650, with commercial systems starting around $800 depending on square footage and access.
Our process starts with negative-air extraction, which means we hook a powerful vacuum to your trunk line to create suction throughout the system while we work. Then we use brush agitation, running rotary brushes through each supply and return to knock debris loose from the duct walls. The loosened material gets pulled out under continuous negative pressure, and our Abatement Technologies HEPA filtration captures particles as small as 0.3 microns so they don’t settle back into your rooms.
Supply and Return Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. In Boyes Hot Springs, we often find the returns more contaminated than the supplies because they’re drawing air through registers that sit low on walls, collecting vineyard dust and wildfire ash that settles near the floor. We clean both sides of the system, not just the vents you can see.
Full System Cleaning
A full system cleaning includes the trunk lines, branch ducts, registers, grilles, and the air handler cabinet. We frequently find that the blower motor and evaporator coil in Boyes Hot Springs homes are caked with debris that gets redistributed the moment the system cycles. Cleaning the ducts without addressing the air handler is half a job, and we don’t do half jobs.
Air Duct Inspection in Boyes Hot Springs
Air Duct Inspection in Boyes Hot Springs is where we find the problems that explain why your system smells musty or your energy bill climbed last season. We use video inspection, running a camera through the ductwork to document crushed runs, disconnected joints, moisture staining, and mold growth before we quote any cleaning or repair. A typical inspection in Boyes Hot Springs runs $150-$250, and we apply that fee toward your cleaning if you proceed with the work.
The inspection matters especially here because of what we find in older crawlspaces. Pre-1960s galvanized sheet metal runs sweat and corrode faster in Boyes Hot Springs than in drier inland Sonoma County towns. Flexible duct gets crushed by decades of settling or by rodents drawn to the warmth. And the geothermal moisture we mentioned leaves signature mineral deposits that tell us where sealing work is needed, not just cleaning.
Video Documentation
Our camera records what we find, and we show you the footage. You’ll see the moisture rings, the crushed sections, the joints that have pulled apart. This isn’t about upselling; it’s about fixing the actual problem instead of vacuuming around it and hoping for the best.
Written Findings and Quote
After inspection, you get a written report with photos and a single flat price for the work we recommend. One price per system, agreed before we start. No per-vent add-ons, no equipment charges that appear after we’re in your home. The price we write is the price you pay.
Trusted Brands We Service in Boyes Hot Springs
We clean ductwork connected to every major HVAC brand installed in Sonoma Valley homes, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for homeowners who want to maintain clean air between service visits. Our Rotobrush, Nikro, and Abatement Technologies equipment handles the cleaning side; the filtration products handle what comes after. If your system needs a component we don’t carry, we source it fast through our San Francisco Bay Area supply chain. Most Boyes Hot Springs customers get same-week parts availability without us driving to Sacramento or the East Bay.
Common Air Duct Cleaning Problems We See in Boyes Hot Springs Homes
- Geothermal moisture in crawlspace flex duct. The active geothermal ground beneath Boyes Hot Springs wicks moisture into under-floor runs, leaving mineral-stained moisture rings and mold that standard vacuuming won’t remove. We often need to seal or replace these sections, not just clean them.
- Crushed or disconnected pre-1960s ductwork. Original galvanized and uninsulated sheet-metal runs in unconditioned crawlspaces sweat, corrode, and collapse faster here than in drier inland communities. We find crushed or disconnected sections on most older homes we inspect.
- Wildfire ash from the 2017 Nuns Fire. The fire burned the Mayacamas and Sonoma Mountain slopes directly flanking the Valley of the Moon, driving ash deep into HVAC systems of homes that survived. Years later, we still pull gray particulate from trunk lines that never got properly cleaned after the event.
- Vineyard harvest dust accumulation. Each September through November, Sonoma Valley’s dense wine grape harvest generates fine particulate that infiltrates duct systems through gaps in crawlspace construction. This agricultural dust layer adds to the normal household debris and can aggravate respiratory conditions if not removed.
Pricing for Air Duct Cleaning in Boyes Hot Springs, CA
Most homes in Boyes Hot Springs run $350-$650 for a complete residential air duct cleaning. Commercial systems start around $800 and scale with square footage, number of air handlers, and access difficulty. What moves you within that range? The size of your system, how many trunk lines and branches you have, whether we find damaged ductwork that needs sealing or replacement, and how contaminated the system is when we inspect it.
We don’t quote per-vent pricing. That’s the bait-and-switch model: a low teaser rate per vent that balloons once the technician counts them up. Our price is one flat fee per system, written in your hands before we touch a single vent. The inspection fee of $150-$250 applies toward your cleaning if you proceed. Estimates are free if you call (469) 972-3151 and describe your system. We’ll give you an honest range so you know what to expect before we schedule.

FAQs About Air Duct Cleaning in Boyes Hot Springs
Cleaning removes loose debris, but it won’t fix flex duct that’s saturated with geothermal moisture or structurally degraded. If our inspection shows mineral-stained moisture rings, mold penetration, or crushed sections, we recommend sealing or replacement of the affected runs. We’ll show you the camera footage and quote both options so you can decide. Call (469) 972-3151 for a free inspection.
Boyes Hot Springs sits directly above active geothermal ground, and that elevated subsurface moisture wicks into crawlspaces and under-floor ductwork in ways that don’t occur a few miles north or east. Our technicians regularly pull flex duct sections from the historic bathhouse district that are visibly stained with mineral deposits and moisture rings. The cleaning process is similar, but the preparation and follow-up sealing work is often more extensive here. Call (469) 972-3151 and we’ll explain what we typically find in homes like yours.
Yes, if your home was in the smoke plume and your ducts haven’t been professionally cleaned since 2017. Wildfire ash is fine enough to penetrate closed systems, and it settles in trunk lines and blower motors where it gets redistributed with every cycle. We still find gray particulate in Boyes Hot Springs systems that were never properly addressed after the fire. An inspection will tell you definitively. Call (469) 972-3151 to schedule one.
We run a video camera through your supply and return ductwork to document crushed runs, disconnected joints, moisture staining, mold growth, and debris accumulation. We also inspect the air handler cabinet, blower motor, and evaporator coil. You receive written findings with photos and a single flat-price quote before any cleaning begins. The $150-$250 inspection fee applies toward your cleaning if you proceed.
Yes, dryer vent cleaning is our second confirmed service, and we recommend it for Boyes Hot Springs homes because vineyard harvest dust settles everywhere, including the lint trap bypass and exterior vent hood. A clogged dryer vent is a fire hazard and extends drying times. We can schedule duct and dryer vent cleaning together, and you’ll get a written price for both before we start. Call (469) 972-3151 for a combined estimate.
