Expert boiler repair, installation, and radiant heating for San Anselmo homes — from Ross Valley bungalows to the Sleepy Hollow hills.
San Anselmo's older Ross Valley homes — the 1920s Craftsman bungalows near The Hub, the mid-century houses climbing into Sleepy Hollow and Sais Acres — were often built around hydronic heat, and many still run on aging boilers that struggle through damp, fog-chilled winter mornings. When a circulator quits, a zone goes cold, or pressure keeps dropping on a hillside system, you want a crew that already knows how these radiant setups behave. John Owens Services has kept Marin homes warm since 1986, with same-day boiler repair and a fully licensed team (CA #501853) that diagnoses it right the first time.
We offer same-day boiler repair across San Anselmo and Ross Valley whenever possible, and our trucks carry the common circulators, valves, and controls to finish most repairs in one visit. As a fully licensed contractor (CA #501853), we restore heat safely and correctly.
Yes — radiant heating delivers the quiet, even, draft-free warmth that suits San Anselmo's older bungalows and hillside homes, and it pairs beautifully with the damp, cool Ross Valley climate. We service existing radiant floors and radiators and design new low-temperature systems.
We start with accurate load sizing for your radiant or radiator system, give you a clear written estimate, and install a right-sized high-efficiency or condensing boiler — often replacing an aging cast-iron unit. Every boiler installation is performed by our licensed team (CA #501853).
Once a year, ideally before the foggy fall and winter set in. Annual maintenance — flushing, combustion testing, and a safety check — keeps your radiant heating efficient and catches small issues before they become a cold-morning emergency.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
