John Owens Services has served Marin and Sonoma County homeowners since 1986. Our local team handles plumbing, drains, water heaters, heating, cooling, radiant systems, and ductless comfort upgrades across the North Bay.

Every visit follows the John Owens Way: maintain first, repair when practical, and recommend replacement only when it is the right long-term option. You get clear findings, practical choices, and work that starts only after you approve it.

Local Conditions We Plan For

The same repair can call for a different approach depending on where the home sits. Our technicians plan around the local conditions that commonly affect Marin and Sonoma houses.

  • Coastal salt air: homes near the bay and ocean can see faster corrosion on pipes, fittings, and outdoor equipment, so materials and finishes matter.
  • Wildfire smoke: inland smoke season makes filtration and indoor air quality more important for many households.
  • Older homes and Eichlers: many classic homes were not built with ductwork, so heating and cooling recommendations need to fit the house instead of forcing the wrong system into it.

Services We Handle Across Both Counties

Homeowners can call one local team for the systems that keep the house safe, clean, and comfortable.

  • Plumbing: leak detection, pipe repair, fixture replacement, repiping, and everyday plumbing repairs.
  • Drains: drain cleaning, hydro-jetting for tough blockages, and root removal in older sewer lines.
  • Heating: forced-air, radiant, boiler, furnace, and heat pump service, including tune-ups and troubleshooting.
  • Cooling: air conditioning repair and installation, plus ductless options for homes without traditional ductwork.
  • Water heaters: repair and replacement for tank, tankless, and heat pump water heater systems.

Discounts and Financing

Good service should be straightforward to plan for. Current offers available across Marin and Sonoma County include:

  • $200 off an installation, such as a new water heater, furnace, or air conditioning system.
  • $35 off a standard repair visit.
  • Veteran and senior discounts: $200 off an installation or $50 off a repair.

Offers cannot be combined, and veteran or senior discounts apply to either an installation or a repair on the same job. For larger projects, financing options may help spread the cost over time. Mention any discount or financing need when you schedule.

Frequently Asked Questions

Do you serve all of Marin and Sonoma County, including West Marin?

Yes. We serve homeowners across both counties, from coastal West Marin communities to inland towns like Santa Rosa and Petaluma. The recommendations may change by area because water, salt air, access, ductwork, and climate conditions vary from house to house.

Can you heat or cool an older home that has no ductwork?

Yes. Many classic Marin and Sonoma homes, including Eichlers, were never built with ducts. We look at options that fit the layout of the home instead of forcing a system the house was not designed for.

Does coastal salt air affect plumbing and HVAC work?

It can. Homes near the bay and ocean often see faster corrosion on pipes, fittings, and outdoor equipment. We account for that when choosing materials, repairs, and replacement recommendations.

Will you replace my system or try to repair it first?

We follow the John Owens Way: maintain first, repair where we can, and recommend replacement only when it is genuinely the right call. We explain your options and the trade-offs before any work begins.
