Sebastopol's housing runs old and characterful — 100-year-old Craftsman bungalows near downtown, farmhouses out toward Green Valley, and original hydronic systems that have heated apple-country families for generations. Those aging boilers and radiant loops work overtime here, where coastal fog rolls in off the Gravenstein Highway and evenings stay cool well into summer. John Owens Services has repaired, replaced, and dialed in boilers and radiant heat across Sonoma County since 1986, and we know exactly what these homes need.

Why Sebastopol Homeowners Choose John Owens

  • Hydronic specialists, not generalists — we troubleshoot the gas valves, circulator pumps, and zone controls on the older boilers common in Sebastopol's pre-war and mid-century homes, not just swap parts and hope
  • Same-day service when the heat quits on a damp, fog-bound evening — no waiting days with a cold house
  • Licensed (CA #501853), insured, and family-run since 1986, with a 4.9-star Google rating and happy customers from neighbors across Marin and Sonoma
  • Honest assessment on repair-versus-replace for a 20- or 30-year-old boiler, with straight pricing before any work begins
  • Comfortable with rural Green Valley and Mills Station properties — propane-fired systems, well-water mineral buildup, and detached-structure runs included
  • We respect the house — careful work in tight bungalow basements, crawlspaces, and finished radiant-floor rooms

Signs You Need Boiler & Radiant Heating in Sebastopol

  • No heat or uneven heat — some rooms warm, others cold — often a failing circulator pump or air-bound radiant loop
  • Banging, gurgling, or rumbling from the boiler, or visible leaks and corrosion around the unit and fittings
  • Pilot or burner that won't stay lit, or a boiler short-cycling on and off without warming the home
  • Hot water that runs out fast or never gets hot — a sign your water heater is failing and due for replacement
  • A boiler past 15-20 years old, with rising fuel bills, that's a strong candidate for a high-efficiency upgrade

Frequently Asked Questions

How fast can you get to a boiler repair in Sebastopol?

We offer same-day boiler repair across Sebastopol and the surrounding Sonoma County area whenever scheduling allows, so a cold house on a foggy night doesn't have to wait. We're licensed (CA #501853) and fully insured.

Do you service older radiant heating systems in Sebastopol's Craftsman and farmhouse homes?

Yes — radiant and hydronic heat is a core specialty. We regularly diagnose air-bound loops, tired circulator pumps, and zone-valve issues in Sebastopol's century-old bungalows and Green Valley farmhouses.

Should I repair or replace my old boiler?

If your boiler is over 15-20 years old and needs a major repair, a high-efficiency replacement often pays for itself in lower fuel bills. We'll give you an honest side-by-side before any work starts.
