Duct sealing, filtration, airflow, and indoor air quality service for Marin and Sonoma homes with leaky, stale, smoky, or poorly balanced air.
This is the broader duct and indoor-air-quality hub. If the main problem is debris inside the duct runs, start with our air duct cleaning services. If the problem is leaky ductwork, weak airflow, smoke intrusion, stale rooms, or filtration that cannot keep up, John Owens Services can inspect the whole system and recommend the right fix.
Duct cleaning removes debris from inside the runs. Duct sealing closes leaks that waste conditioned air and pull dirty attic or crawlspace air into the system.
Yes. Those homes are common in our service area and often need careful duct inspection, return-air correction, sealing, or filtration work.
It can. We focus on practical improvements: sealed ductwork, better filtration, cleaner returns, and airflow that does not drag smoke residue or attic dust through the house.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
