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.

AfterAir Duct Cleaning Company in Petaluma, CA
Air duct cleaning in Petaluma runs $350 – $650 for most homes, with floodplain properties near the river often landing higher due to moisture damage and mold remediation needs. We’re Hollis Air Duct Cleaning, and our crews work Petaluma’s mix of Victorian-era housing and mid-century tract homes with equipment built for both delicate old ductwork and modern flexible systems. Call (361) 326-5060 for a written estimate before any work starts.
Why Petaluma Homes Are Different
Petaluma sits on a river floodplain, and that geography changes everything about what we find inside local ducts. The cool, foggy mornings and seasonal rain keep indoor humidity elevated for much of the year, which accelerates rust in metal ductwork and encourages mold growth inside crawlspaces and attics. After wet winters, we regularly see homes near the Petaluma River with ducts packed with silt and mold spores that require full replacement rather than cleaning alone.
The housing stock splits sharply by era. Downtown and the historic riverfront are dense with pre-1930 Victorian and Craftsman homes, many still running original octopus gravity furnaces with undersized, leaky metal ductwork prone to corrosion. East and west of downtown, 1960s – 1990s tract homes typically have flexible ducting that traps debris and can harbor pests. Each type demands a different approach, and we size the job accordingly.
Our Main Petaluma Services
Most Petaluma homeowners call us for one of three jobs. Each has its own page with full pricing and details.
Air Duct Cleaning in Petaluma
We clean supply and return ducts with Rotobrush rotary brush systems and Nikro negative-air machines, pulling debris out rather than pushing it deeper. In Petaluma’s older homes, we often start with a moisture assessment because fog and river proximity mean mold remediation runs ahead of standard dust removal. Air Duct Cleaning in Petaluma
Dryer Vent Cleaning in Petaluma
Lint buildup in dryer vents is a fire hazard, and Petaluma’s humid climate can compress lint into dense blockages that restrict airflow further. We run brushes and high-velocity air through the full line to the exterior cap, then verify flow with a meter. Dryer Vent Cleaning in Petaluma
Duct Sealing in Petaluma
Leaky ducts waste 20 – 30% of heated and cooled air, and Petaluma’s older gravity-furnace systems are especially prone to gaps at joints and registers. We seal with mastic and metal-backed tape, then pressure-test to confirm the fix holds. Duct Sealing in Petaluma
