Licensed AC repair, maintenance, and ductless cooling for San Anselmo's older Ross Valley homes — same-day help when the heat climbs.
San Anselmo sits inland in the Ross Valley, so when summer afternoons settle over the Hub and Sleepy Hollow there's no coastal fog to take the edge off the way there is in Mill Valley or Tiburon. Many of the town's early-1900s bungalows and Craftsman homes in Seminary, Yolanda, and Winship Park were built with radiators or wall furnaces and never had cooling at all, which makes a clean ductless retrofit or a well-tuned existing system the difference between a comfortable house and a stuffy one. John Owens Services has been the licensed local crew (CA #501853) handling that work since 1986.
John Owens Services has repaired and installed cooling systems for San Anselmo homes since 1986 and is fully licensed (CA #501853). We offer same-day AC repair whenever possible, with trucks stocked to fix most failures on the first visit.
Ductless mini-splits are usually the best fit for the town's early-1900s bungalows and hillside homes, giving you quiet, zoned cooling without adding ducts. We size and install them to handle the rooms that actually overheat in the Ross Valley.
Once a year, ideally in spring before the inland heat arrives. Annual AC maintenance keeps efficiency up, catches small issues early, and is especially worth it during smoke season when you're relying on the system with the windows closed.
More homeowners do every year — San Anselmo runs warmer than coastal Marin because the valley misses the marine fog, and summer afternoons in town can get genuinely hot. We help you choose right-sized, efficient cooling for your specific home.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
