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.
Air Duct Cleaning Company in Windsor, CA
Air duct cleaning in Windsor, CA typically costs $350 – $650 for a whole-home system and should be scheduled every 3 – 5 years due to the area’s unique geothermal and wildfire exposure. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve Windsor from our San Francisco Bay Area dispatch office. Windsor’s location downwind of the Geysers geothermal field and surrounded by Russian River Valley vineyards creates duct contamination patterns you won’t find in other Sonoma County towns. Call us at (361) 326-5060 for a free estimate with a written price before any work starts.
Why Windsor Homes Are Different
Windsor sits in a pocket of Sonoma County where geology and climate collide inside your ductwork. The Geysers geothermal field to the northeast releases sulfur compounds and fine particulates that drift into Windsor’s air supply, especially when prevailing winds blow southeast. We’ve opened return vents in homes near Foothill Regional Park and found thin gray film coating the interior surfaces, distinct from ordinary household dust.
The housing stock tells its own story. Much of Windsor was built between the 1980s and 2000s, tract homes and custom builds with flexible ductwork and standard fiberglass insulation. These materials trap pollen from the surrounding oak woodlands and vineyard country more readily than metal systems. Older pockets downtown still have post-war ranch homes with original galvanized ducts, prone to rust at the seams and heavier debris buildup where decades of geothermal particulate have settled.
Summer heat spikes push Windsor HVAC systems hard, and when coastal fog finally burns off, the temperature swing stresses duct connections. After the September 2020 Glass Fire, we saw a surge of calls from homeowners who discovered fine black ash had been drawn through return leaks and distributed room to room. Local crews now check for smoke odor and black dust in returns as standard practice, especially along the Foothill Regional Park corridor where the fire’s edge came closest.
Our Main Windsor Services
We handle three core services for Windsor homeowners, each with its own local conditions and equipment requirements.
Air Duct Cleaning in Windsor
Our Air Duct Cleaning in Windsor uses Rotobrush rotary brush systems and Nikro negative-air machines to remove the fine ash, pollen, and geothermal particulate that accumulate here. We pay special attention to return plenums and trunk lines where wildfire residue tends to concentrate. Every job gets a written price before we start, and we photograph your ducts before and after so you see what came out.

Dryer Vent Cleaning in Windsor
Our Dryer Vent Cleaning in Windsor addresses lint buildup that accelerates in dry summer conditions and can ignite when vents run long through 1980s-era construction. We clear the full run from appliance to termination, test airflow with a manometer, and flag any flexible transition hose that needs replacing with solid metal per current code. The 365-Day Done Right Promise covers this work too.

Duct Sealing in Windsor
Our Duct Sealing in Windsor targets the return leaks that pull in unfiltered air from attics and crawl spaces, especially critical here where geothermal sulfur and wildfire smoke enter so easily. We use mastic and metal-backed tape on accessible joints, then pressure-test the system to verify sealed performance. Homes with original flexible ductwork from the 1990s often see the biggest efficiency gains.
