Air duct cleaning, duct sealing, and indoor air quality for Marin and Sonoma County homes carrying wildfire ash, coastal damp, and decades of buildup.
Between the smoke seasons that have settled over the North Bay since the Tubbs and Glass fires and the fog-fed damp that rolls in off the coast, the ductwork in a lot of Marin and Sonoma homes is quietly recirculating ash, pollen, and the start of mildew. It shows up in the houses we know well here: the 1950s and '60s Eichlers and ranch tracts in Terra Linda, Novato, Santa Rosa, and Petaluma, where original sheet-metal runs and undersized returns trap everything the system pulls in. John Owens Services has cleaned, sealed, and rebalanced those duct systems across both counties since 1986, and we treat it as airflow and air-quality work, not a vacuum-and-go upsell.
Cleaning removes the settled ash and soot a system has pulled in and is recirculating, and we usually pair it with better filtration or duct sealing so the next smoke event stays out. We serve all of Marin and Sonoma and can often come the same day during fire season.
Cleaning clears the dust, debris, and buildup inside the runs, while duct sealing closes the leaks that let conditioned air, attic dust, and crawlspace damp into the system before it reaches your rooms. Older Marin and Sonoma ductwork often needs both, and we use Aeroseal for the sealing.
These homes often have original sheet-metal ducts, weak returns, and gaps that pull in unfiltered air, so cleaning plus sealing and upgraded filtration cut the dust, pollen, and odors actually circulating. Our licensed technicians (CA #501853) inspect the whole system before recommending anything.
Yes. We are family-run, licensed (CA #501853), and dispatch fully stocked trucks throughout both counties, so most duct cleanings and many related repairs are handled in a single same-day visit.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
