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 Windsor
Air duct cleaning in Windsor, CA typically costs $350 – $650 for a single residential system and $900 – $1,800 for a full three-system home, with most jobs completed in one visit and camera documentation provided before we leave. We’re the Air Duct Cleaning team that serves Windsor from our San Francisco Bay Area dispatch office, and we know the local conditions that shape what actually ends up in your ducts.
Windsor’s mix of 1980s-2000s tract homes with flexible ductwork, custom builds off Foothill Regional Park Drive, and older downtown ranch homes with original metal ducts means no two jobs are identical. Many Windsor homes run multiple HVAC systems, and we’re structured to price per system so the longest flex-duct runs get the same attention as the shortest. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Windsor’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Windsor customers come back because we show up inside the quoted window, price the job in writing before we touch anything, and leave the site clean. That’s The Garrison Standard, and it’s how every Hollis location operates, independently owned and operated.
Our technicians are background-checked and uniformed, and you know who’s arriving before they walk through your door. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops or callback queues. The 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit.
We know Windsor’s specific challenges. The Geysers geothermal field sits upwind, so sulfur-tinged fine particulate drifts into ducts here in ways coastal cities don’t experience. The 2020 Glass Fire pulled ash through return leaks in homes along the Foothill Regional Park corridor, and Russian River Valley pollen plus coastal fog moisture create conditions that reward thorough work and punish shortcuts. We price per system because a three-system home off Shiloh Road deserves the same standard as a single-system ranch near Windsor Town Green.
Air Duct Cleaning Services in Windsor
Air Duct Cleaning Services in Windsor involve source removal of dust, debris, and particulate from your entire duct network using professional-grade equipment. We serve Windsor homeowners with residential systems, commercial properties near the Windsor Business Park, and multi-system custom homes throughout the Foothill Regional Park area. A typical single-system residential job in Windsor runs $350 – $650; commercial systems start around $800 and scale with square footage and access complexity.
Residential Duct Cleaning
Windsor’s housing stock leans heavily toward homes built between the 1980s and 2000s, many with flexible ductwork and fiberglass insulation that traps debris. We use Rotobrush rotary brush systems to agitate and loosen buildup, then extract it with negative-air machines. Per-system pricing means your master suite system gets the same runtime as the main living area system, no matter how long the flex runs are.
Commercial Duct Cleaning
Businesses near Old Redwood Highway and the Windsor Business Park need scheduled work that doesn’t disrupt operations. We coordinate after-hours and weekend slots, use Nikro negative-air equipment to contain debris during the job, and provide written documentation for property managers and compliance records.

HVAC Duct Cleaning in Windsor
HVAC Duct Cleaning in Windsor addresses the full mechanical system: supply ducts, return ducts, blower motor housing, evaporator coils, and plenum boxes where debris collects and recirculates. We serve Windsor with both maintenance cleaning and post-event recovery, particularly after wildfire smoke intrusion or seasonal pollen overload. A full system cleaning in Windsor typically runs $450 – $850 for a single residential unit, with multi-system homes priced per system starting at $350 each.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back. In Windsor, return ducts are especially vulnerable because they operate under negative pressure, sucking in geothermal particulate, wildfire ash, and pollen through any leak in the building envelope. We clean both sides of the loop and seal the leaks we can access, so your freshly cleaned ducts stay clean longer. For a more permanent solution, ask about Duct Sealing in Windsor.
Video Inspection and Documentation
Every Windsor job includes camera inspection of key access points, with before-and-after photos of your own ducts provided before we leave. You see what we saw, what we removed, and what the finished run looks like. This matters in Windsor, where much of the contamination is fine particulate you cannot see with a flashlight.
Trusted Brands We Service in Windsor
We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Windsor customers who want to upgrade after cleaning. Rotobrush rotary brush systems handle the flexible ductwork common in Windsor’s 1990s tract homes; Nikro negative-air machines contain debris during commercial jobs; and Aprilaire media filters help block the fine pollen that drifts in from Russian River Valley vineyards. Parts and filters are available with fast turnaround, so you’re not waiting on a Bay Area warehouse to ship.
Common Air Duct Cleaning Problems We See in Windsor Homes
- Geothermal particulate buildup from The Geysers. Windsor sits downwind of the largest geothermal field in the world, and sulfur-tinged fine dust settles in ducts over time. Standard pollen rinses don’t remove it; source removal with agitation and negative-air extraction does.
- Wildfire ash in return systems post-2020 Glass Fire. Many homes along the Foothill Regional Park corridor still recirculate fine black dust that entered through return leaks during the fire. We check blower motor housings and plenum boxes where this material hides.
- Moisture and mold in fog-exposed ductwork. Coastal fog that rolls into the Russian River Valley can introduce moisture through crawl space leaks, especially in older downtown homes with original metal ducts prone to rust.
- Undersized or crushed flex ducts in 1980s-2000s tract homes. Builders in the Shiloh Oaks and Windsor Creek areas often used minimum-spec flexible ductwork that degrades, crimps, or disconnects, reducing airflow and trapping debris.
Pricing for Air Duct Cleaning in Windsor, CA
Single-system residential air duct cleaning in Windsor runs $350 – $650. Two-system homes typically fall at $700 – $1,100. Three-system custom homes, common in the Foothill Regional Park area and off Shiloh Road, run $900 – $1,800 depending on total duct footage and access difficulty. Commercial systems start around $800 and scale with square footage.
What moves the price: number of systems, total linear feet of ductwork, access conditions (crawl space vs. attic vs. conditioned space), and whether post-wildfire or heavy contamination requires extended HEPA containment and multiple agitation passes. We write the price down before any work starts, and it does not move at the door. No per-vent pricing, no add-ons once we’re inside. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Windsor
Because a three-system home with long flex-duct runs takes three times the equipment runtime and technician attention of a single-system ranch, and flat-rate pricing incentivizes crews to rush the biggest systems. We price per system so your master suite unit gets the same thorough agitation, negative-air extraction, and camera documentation as your main living area unit. Call (361) 326-5060 for a written estimate on your specific home.
No. Source removal eliminates the sulfur-tinged particulate that causes odor; sealing accessible return leaks prevents new geothermal dust from entering. If your ducts smelled before cleaning, the odor came from debris buildup, not the duct material itself. We document the before condition with camera inspection so you can verify the change.
Camera inspection is standard on every job, because much of what contaminates Windsor ducts, fine ash from wildfires and geothermal particulate, is not visible from a register opening. You get before-and-after photos of your own ducts, not stock images, plus a written system-by-system report. This is especially important in Windsor, where post-2020 Glass Fire ash can hide in blower motor housings and return plenums.
Written price before work starts, before-and-after photos of every supply and return run we access, a system-by-system report noting any damage or leaks found, and the 365-Day Done Right Promise in writing. For multi-system homes, we break out each unit separately so you know which system required what work. This documentation protects you and holds us accountable to The Garrison Standard. Call (361) 326-5060 to schedule.
Windsor pricing sits in the same range as Healdsburg and slightly below Santa Rosa’s denser, harder-to-access urban housing stock. A single-system home in Windsor, Healdsburg, or Sebastopol typically runs $350 – $650; Santa Rosa’s older, tighter construction sometimes pushes toward the higher end of that range. Multi-system custom homes are common in Windsor’s Foothill Regional Park area and can run higher than standard Santa Rosa tract homes. We quote each job specifically; estimates are free.
