Tankless water heater installation, repair, and tank replacement across Marin & Sonoma County — same-day service from a licensed local team.
From the 1920s Victorians of San Rafael to the mid-century ranches of Santa Rosa and the rural propane homes out toward West Marin, North Bay houses run hard on their water heaters — and our mineral-heavy local supply scales up tanks and tankless coils faster than most homeowners expect. John Owens Services has installed, flushed, and repaired water heaters across Marin and Sonoma County since 1986, sizing each tankless unit to your home's real winter inlet temperatures and gas line so you actually get the endless hot water you paid for. When a tank fails or a tankless unit throws an error code, we answer the phone and most days we're there the same day.
For most North Bay homes, yes — a tankless water heater delivers endless hot water, frees up garage or closet space, and can last 20+ years, especially with regular descaling for our hard local water. We'll assess your gas line, venting, and demand before recommending one, since an older home may need an upgrade to support it.
Yes. We provide same-day water heater repair across Santa Rosa, Petaluma, San Rafael, Novato, and the surrounding North Bay, and most repairs are completed in a single visit. Call our local lines and we'll get a licensed tech (CSLB #501853) out fast.
Cost depends on whether you choose a tank or tankless unit and what your home's gas, venting, and electrical need — we give a clear quote up front. We also help homeowners capture available California efficiency and gas-to-electric rebates, plus we offer veteran and senior discounts on installs.
Cold incoming water in the North Bay winter lowers a tankless unit's effective flow rate, so an under-sized or scaled-up unit can't keep up with two fixtures at once. We descale the heat exchanger and confirm the unit is properly sized for your home — often the real fix is correct sizing, not replacement.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
