Sonoma County homes ask a lot of their plumbing and HVAC: hard well and municipal water that scales up water heaters, 1970s-and-older housing stock with furnaces buried in tight crawlspaces, propane heat out in the rural stretches past Sebastopol and Healdsburg, and inland summers in Santa Rosa and Rohnert Park that swing 40 degrees from a foggy morning. John Owens Services has worked on exactly these systems since 1986 — a licensed (CA #501853), family-owned crew that handles plumbing, heating, and cooling under one roof. From a clogged main to a failed heat pump to a leak you can hear but can’t find, we diagnose it right the first time and offer same-day appointments across the county.

Why Homeowners Choose John Owens

  • One family-owned team for plumbing, heating, AND cooling — fully licensed for plumbing, HVAC, electrical, and boilers, so a furnace swap or heat pump install doesn't turn into three separate contractors
  • Nearly 40 years on Sonoma County's specific housing stock: crawlspace and attic furnaces, ductwork that leaks ~30%, hard-water-scaled tanks, and propane systems in the rural west county
  • The John Owens Way — we maintain first, repair second, and only replace as a last resort, so you're never upsold into equipment you don't need (a point our hundreds of 5-star five-star reviewers mention by name)
  • Heat pump and high-efficiency specialists who handle the BayREN, Sonoma Clean Power, and rebate paperwork for you, turning the move off gas into real savings
  • Rinnai Authorized Service Providers — tankless water heaters we install carry the full 12-year manufacturer warranty, which a DIY or improper install voids
  • Local crews dispatched from Santa Rosa and Petaluma mean genuine same-day response, not a callback from a regional call center

Signs You Need All Services in

  • No hot water, rusty water, or popping/rumbling from the tank — classic hard-water scale buildup on Sonoma County water heaters
  • A furnace that won't fire, short-cycles, or blows cold, or an AC that can't keep up on a 95-degree Santa Rosa afternoon
  • A water bill that jumped for no reason, the sound of trickling water with every faucet off, or pooling and musty smells near a slab or wall
  • Rooms that never get comfortable, high energy bills, or visible dust — often leaky ductwork or an aging, undersized system
  • You want to electrify — swap gas for a heat pump or heat pump water heater — and need someone to size it right and file the rebates
