Family-run plumbing, heating, and cooling serving homes across Marin and Sonoma County, California since 1986.
John Owens Services has worked on homes across Marin and Sonoma County since 1986. Over those decades we have learned what local houses actually need, from coastal cottages in West Marin to inland neighborhoods around Santa Rosa and Petaluma, and we bring that experience to every visit.
We follow the John Owens Way: maintain first, repair where we can, and recommend replacement only when it is genuinely the right call. We show up on time, explain what we find in plain terms, and only do the work you approve.
Where We Work
We serve homeowners throughout both counties and the towns in between, including the coast, the valleys, and the hillside neighborhoods that each come with their own challenges.
Sonoma County: Santa Rosa, Petaluma, Rohnert Park, Sebastopol, Windsor, Cotati, Penngrove, Glen Ellen, and the surrounding area.Marin County: San Rafael, Novato, Mill Valley, Larkspur, Corte Madera, San Anselmo, Fairfax, Tiburon, Sausalito, and West Marin communities such as Point Reyes Station, Inverness, Bolinas, and Stinson Beach.
Local Conditions We Plan For
The same job can call for a different approach depending on where a home sits. A few local conditions shape the work we do here:
Salt air near the coast. Homes close to the bay and the ocean see faster corrosion on pipes, fittings, and outdoor equipment, so we choose materials and finishes that hold up to the salt air rather than fail early.Wildfire smoke. Smoke season is part of life inland, and we can fit homes with filtration that helps keep indoor air cleaner when conditions outside are poor.Older homes and Eichlers without ductwork. Many classic Marin and Sonoma homes, including Eichlers, were never built with ducts. We work with the heating and cooling options that suit these layouts instead of forcing a system the house was not designed for.
What We Handle
We are a single local team for plumbing, heating, and cooling, so most home systems can be handled by the same people who already know the area.
Plumbing: leak detection and repair, fixture replacement, pipe repair, and repiping built to stand up to local water and coastal conditions.Drains: drain cleaning, hydro-jetting for tough blockages, and root removal in older sewer lines.Heating: service for forced-air, radiant, and boiler systems, including tune-ups, troubleshooting, and efficiency improvements.Cooling: air conditioning repair and installation, plus options for older homes that were never built with ductwork.Water heaters: repair and replacement for both tank and tankless units.
Offers & Financing
Good service should not cost more than it has to, so we keep a few straightforward discounts available to customers across Marin and Sonoma County:
$200 off any install, such as a new water heater, furnace, or air conditioning system.$35 off any repair on a standard service visit.Veteran and senior discounts: $200 off an install or $50 off a repair.
Offers cannot be combined, and the veteran or senior discount applies to either an install or a repair, not both on the same job. For larger projects, financing options are available so the cost of a replacement can be spread over time rather than paid all at once. Just mention what you qualify for when you schedule.

It does. Homes near the bay and ocean see faster corrosion on pipes, fittings, and outdoor equipment, so we choose materials and finishes that hold up to salt air to help the work last.
