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 Sebastopol
Air duct cleaning in Sebastopol typically runs $380-$720 for a full residential system, with most mid-century homes falling in the middle of that range. We’re usually scheduling within a few days, and our crews work Sebastopol from the central neighborhoods out to the west-side orchard edges. Call (469) 972-3151 for a free written estimate.
Sebastopol’s housing stock is different from Santa Rosa’s. The core of town is built out with 1940s-to-1970s bungalows and ranch homes, many originally heated by wall furnaces or wood stoves and retrofitted with forced air decades later. Those retrofit duct runs snake through damp crawl spaces and unconditioned attics, and they fail in predictable ways we’ve learned to spot before we even unload the van. Our Air Duct Cleaning team has worked enough of these farm-era homes to know where the crushed returns hide and which crawl spaces stay wet enough to grow mildew inside galvanized trunk lines.
We dispatch and schedule from our San Francisco Bay Area office, but the crew that arrives at your Sebastopol door knows the local building patterns. They’ll check for the disconnected runs we find under homes off Bodega Avenue, the moisture pooling in low-lying neighborhoods near the Laguna de Santa Rosa, and the pollen loading that hits hardest when the Gravenstein orchards bloom.
Why Kestrel Air Duct Cleaning Is Sebastopol’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Sebastopol by treating the actual problem, not just running a brush through the visible ducts and collecting a check. Homeowners here call us back because we document what we find with camera footage, put the fix in writing, and stand behind it with the 365-Day Done Right Promise.
Our technicians are background-checked, uniformed, and trained on the Kingswell Way values: say the price before touching a vent, show up in the window we gave, leave the job site cleaner than we found it, and put the guarantee in writing. If the work falls short within a year, we return at no charge. That’s not a courtesy we extend when we feel like it. It’s documented on every invoice.
Calls are answered by a live person, any time of day. No voicemail tree, no callback queue. When you’re trying to figure out why your Sebastopol home smells musty every summer afternoon, you talk to a human who can get a technician scheduled.
We serve Sebastopol with the same equipment we’d use on a commercial job: Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-pressure units to pull it out without redistributing it through your house, and Abatement Technologies HEPA filtration to keep loosened particles contained during cleaning. These aren’t shop vacs from a hardware store. They’re purpose-built for ductwork.
Air Duct Inspection in Sebastopol
Air Duct Inspection in Sebastopol is where we start every job, because these retrofitted systems hide problems that a surface look won’t catch. For $180-$280, we run a video camera through the full duct network, document the condition of the trunk lines, and flag any disconnected, crushed, or biologically contaminated runs before we quote cleaning or sealing work.
What We Document on Camera
The inspection records debris type and depth, moisture staining, joint separation, and structural damage. In Sebastopol’s fog-corridor climate, we’re specifically looking for mildew on metal surfaces and standing water in low points of the duct run. The footage goes to you, not just to us.
When to Schedule an Inspection
Book an inspection if you’ve noticed musty odors when the system cycles, uneven heating or cooling between rooms, or a spike in allergy symptoms during the Gravenstein bloom in late April. These are early signals that the ducts are moving contaminants, not just air.
Residential Air Duct Cleaning in Sebastopol
Residential Air Duct Cleaning in Sebastopol addresses the full forced-air system: supply ducts, return ducts, registers, grilles, the air handler cabinet, and the blower motor. A typical home runs $380-$720 depending on system size, accessibility, and whether we find damage that needs sealing or reconnection. We don’t quote per-vent pricing. One flat price per system, agreed in writing before work starts.
Source Removal and Containment
We use negative-air extraction, which means the Nikro unit pulls a vacuum on the duct system while the Rotobrush agitates debris loose. The Abatement Technologies HEPA filter captures particles down to 0.3 microns so nothing escapes into your living space during the job. It’s thorough, and it’s contained.
Post-Cleaning Verification
After source removal, we camera-inspect again to confirm the ducts are clean and the joints are intact. If we found disconnected or crushed runs during the initial inspection, we seal or reconnect them before we close up. Cleaning alone won’t fix a musty smell if damp crawl-space air is still pouring in through a gap.
Trusted Brands We Service in Sebastopol
We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Sebastopol homeowners who want to maintain cleaner air between service visits. The persistent moisture here means standard fiberglass filters often load up faster than in drier climates, so we typically recommend a higher-efficiency pleated option sized to your system. If your furnace or air handler is due for replacement, we can spec compatible media filters and cabinet upgrades that fit the tighter construction of these older retrofit installations.
Common Air Duct Cleaning Problems We See in Sebastopol Homes
- Biological growth in metal ducts. Sebastopol’s marine-fog humidity keeps relative humidity elevated through summer afternoons, promoting condensation on cool metal duct surfaces. We find mildew coating supply trunks in crawl spaces that Santa Rosa crews rarely encounter.
- Crushed or disconnected retrofit returns. The flexible duct installed during 1980s and 1990s forced-air retrofits has often collapsed or pulled loose where it crosses damp earth. The system still runs, but it’s pulling crawl-space air instead of return air from the house.
- Pollen and agricultural dust loading. Late April Gravenstein bloom and July-August harvest season spike particulate counts in west-side neighborhoods near remaining commercial orchards. Return-air filters clog faster, and fine pollen makes it past standard filtration into the ductwork.
- Unsealed attic and crawl-space penetrations. Retrofit installers often cut rough openings through old floors and walls without sealing the gap around the duct. Those leaks pull unconditioned, moist air into the system year-round, recontaminating cleaned ducts within a season.
Pricing for Air Duct Cleaning in Sebastopol, CA
Most full residential systems in Sebastopol run $380-$720. A small bungalow with a simple trunk-and-branch layout might land at the lower end. A larger home with multiple zones, extensive flex-duct damage, or biological contamination requiring antimicrobial treatment can push toward the upper range. Commercial duct cleaning starts around $950 and scales with system complexity.
What moves the price: accessibility of the ductwork, whether we need to enter a wet crawl space or tight attic, the degree of contamination, and any repairs or sealing required. We don’t bait with a low teaser and revise at the door. The written price in your hands before we start is the price you pay.
Air duct inspection is $180-$280 and is credited toward cleaning if you proceed. Dryer vent cleaning, which we also offer, typically runs $150-$250 as a standalone service or can be bundled with duct cleaning.

FAQs About Air Duct Cleaning in Sebastopol
Sebastopol’s persistent marine-fog humidity supports biological growth inside ductwork that Santa Rosa’s drier climate doesn’t. The moisture difference is real and measurable, and it means Sebastopol systems often need attention for mildew and condensation issues rather than simple dust accumulation. Call (469) 972-3151 if you’re noticing musty odors or damp register airflow.
The two heaviest debris windows are late April Gravenstein apple bloom and late July through August harvest season, when orchard pollen and dust chaff load up return-air systems on the west side of town. Scheduling cleaning in May or September lets us remove peak accumulations before they set into the ductwork. Call (469) 972-3151 to book around your property’s exposure.
Cleaning removes biological growth and debris, but the musty smell usually returns unless we also seal disconnected or leaky runs that pull damp crawl-space air. On a 1950s ranch house off Bodega Avenue, our tech pulled a crushed, disconnected return run out of the damp crawl space and found mildew coating the galvanized trunk line. We ran negative pressure with HEPA filtration, used agitation tools on the supply and return ducts and registers, cleaned the air handler and blower motor, and camera-inspected before sealing the joints back up. The homeowner’s musty odor complaints stopped after the reconnect and seal, not after the cleaning alone. Call (469) 972-3151 for an inspection that finds the real source.
Most Sebastopol systems handle MERV 11 pleated filters well during pollen season, but the older blower motors in retrofitted farm-era homes sometimes can’t overcome the airflow resistance of MERV 13 or higher. We check your system’s static pressure during inspection and recommend the highest filtration your equipment can support without straining. Honeywell and Aprilaire make extended-surface filters that capture orchard pollen without the pressure drop of dense pleated media.
Yes, when inspection finds leaks, disconnected runs, or crush damage. We don’t close up without addressing the entry points for moist crawl-space or attic air. The Kingswell Way requires that we leave the system cleaner and more intact than we found it, and that includes sealing joints with mastic and mechanical fasteners where needed. The 365-Day Done Right Promise covers our sealing work if it fails within the guarantee period.
