Trusted furnace repair and installation in Kentfield, CA — keeping Kent Woodlands and Kentfield Gardens homes warm through Marin's cold, wet winters.
Kentfield sits in one of the wettest pockets of Marin, where damp 40-degree nights from November through March keep furnaces running hard for months. Many homes here — the 1950s ranches of Kentfield Gardens and the Seminary district near College of Marin, plus the older estates tucked into Kent Woodlands — still rely on heating systems well past their prime. John Owens Services has repaired, tuned, and replaced furnaces across these neighborhoods since 1986, and we know what a Kentfield winter asks of them.
We offer same-day furnace repair throughout Kentfield and greater Marin County whenever scheduling allows. As a licensed local company (CA #501853) based nearby, we can usually reach Kent Woodlands, Kentfield Gardens, and the College of Marin area quickly, even on cold winter days.
If your furnace is under 15 years old, a repair is often the smart call; once a system passes 15–20 years — common in Kentfield's 1950s housing stock — replacement usually saves more on energy and reliability. We give you an honest assessment either way, never a hard sell.
We assess your home's size, insulation, ductwork, and Kentfield's damp climate to size the system correctly, then handle the full installation and permitting. Proper sizing matters here, since many older homes were fitted with undersized units that struggle through Marin's long, cool winters.
Yes. We regularly work on aging furnaces, long duct runs on large wooded lots, and tight crawlspace installations throughout Kentfield's mid-century and estate homes. Our 40 years of local experience means few setups surprise us.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
