Sebastopol winters are short but genuinely wet and cold — frost mornings from December through March and weeks of damp, gray rain that keep your furnace running hard. Many homes here are 1920s Craftsman bungalows and apple-orchard farmhouses with original ductwork, while rural West County properties off the natural-gas grid lean on propane furnaces that demand a tech who knows how to tune them. John Owens Services has kept Sebastopol families warm since 1986, whether you need a quick repair before the next storm or a full high-efficiency replacement.

Why Sebastopol Homeowners Choose John Owens

  • Family-run and California-licensed (CA #501853) since 1986 — nearly four decades of heating work across Sebastopol and West Sonoma County, backed by a 4.9-star Google rating
  • Same-day furnace repair so a cold, rainy Sebastopol morning doesn't turn into days without heat
  • Real experience with propane furnaces on rural Gravenstein Highway and Bloomfield-area properties that sit off the natural-gas main — not just standard PG&E gas units
  • We work on older Sebastopol housing stock — 1920s bungalows, mid-century ranches, and farmhouse retrofits with tight crawlspaces and undersized original ductwork
  • Honest, upfront pricing with a clear repair-vs-replace recommendation — we'll tell you when an aging furnace is worth fixing and when a new system pays for itself
  • Licensed install of modern high-efficiency furnaces and heat pumps, properly sized for your home's square footage and insulation, not a one-size guess

Signs You Need Furnace Repair & Installation in Sebastopol

  • Furnace short-cycles or won't keep up on a 40-degree Sebastopol frost morning, leaving cold rooms at the far end of the house
  • Yellow or flickering burner flame, a rotten-egg smell, or the CO detector triggering — shut it down and call right away
  • Banging, rattling, or squealing on startup, or a burning-dust smell that never clears after the first cold snap
  • Rising propane or gas bills with no extra usage, often a sign of a furnace dropping below 80% efficiency
  • Your furnace is 15-20+ years old — common for Sebastopol homes last upgraded in the 1990s — and repairs are stacking up

Absolutely. Many West County and Gravenstein-area homes heat with propane, and our techs are experienced installing and tuning propane furnaces — not just standard natural-gas units.

My Sebastopol home is an older bungalow — can you still install a modern furnace?
