Same-day air conditioning repair, installation, ductless mini-splits, and cooling help for Marin and Sonoma homes.
From the fog-cooled hills of Mill Valley and Tiburon to the triple-digit summer afternoons in Santa Rosa, Petaluma, and Healdsburg, comfort in our two counties means very different things house to house. John Owens Services has cooled North Bay homes since 1986 — sizing systems for our microclimates, retrofitting ductless cooling into older Victorians and mid-century homes that were never built with AC, and keeping aging inland condensers running through heat waves and smoke season. Whether your system quit on the hottest day of the year or you're finally adding central air, we diagnose honestly and fix it right the first time.
Yes — we offer same-day AC repair across both counties and our trucks are stocked to finish most jobs in one visit. As a licensed California contractor (#501853), we diagnose the real problem before recommending any work.
Many older Marin and Sonoma homes do best with a ductless mini-split, which avoids the cost of adding ducts and cools specific rooms efficiently. We give a clear, upfront quote after assessing your home's layout, size, and microclimate.
We follow a repair-first approach: if a fair fix gets you reliable seasons, we'll do that. For systems over 15 years old, using phased-out R-22 refrigerant, or failing repeatedly, replacing with a high-efficiency unit usually saves more over time.
Yes — a properly sealed, well-filtered central AC or heat-pump system helps keep smoke and particulates out of your home during fire season. We can recommend upgraded filtration suited to North Bay air-quality conditions.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
