Boiler & Radiant Heating Services in Kentfield, CA

Why Kentfield Homeowners Choose John Owens

• We’ve serviced the original 1960s and ’70s cast-iron boilers common in Kent Woodlands and Greenbrae-side Kentfield homes — we know their quirks before we open the panel
• Radiant and hydronics are a core specialty, not a sideline: zone valves, circulator pumps, expansion tanks, mixing valves, and slab loops are everyday work for our techs
• Same-day service matters when a boiler dies on a damp, tree-shaded lot where the house never warms on its own — we keep trucks stocked to fix it on the first visit
• Licensed California contractor #501853, fully insured, with a 4.9-star Google rating and happy customers from Marin and Sonoma homeowners
• We give straight repair-vs-replace advice — an old boiler can often run another season, and we’ll tell you honestly when high-efficiency replacement actually pays off
• Family-run and local since 1986; we navigate Kentfield’s set-back hillside driveways and tight mechanical rooms without drama
