Boiler replacement, installation and repair, along with radiant heat repair, are what we handle for Marin and Sonoma County homes. When a boiler or radiant system quits, we trace the problem through the boiler, controls, circulators and heating zones, whether you have radiant floors, radiators or baseboards.

A replacement starts with your house, not an equipment catalog. We look at your existing distribution, the home's heating needs, venting and controls, then explain the work and give you a written estimate. We also work with older boilers: tell us the model and symptoms and we will assess repair options and parts availability. Estimates on installations and replacements are free, and financing is available.

Our San Rafael office serves Marin towns including Larkspur, San Anselmo, Mill Valley and Kentfield, and our Santa Rosa and Petaluma offices serve Sonoma County. We follow the John Owens Way: maintain first, repair when needed, replace last. A yearly service before heating season is how leaks, pressure loss and worn parts get caught early.

We look at the whole heating loop

The boiler is one part of a radiant system. We check the pieces around it before suggesting a repair or a replacement.

  • Boiler, controls, circulators, expansion tanks and heating zones all checked
  • Repair options and a written estimate explained before work begins
  • Replacement planned around your existing radiators, baseboards or radiant floors
  • Familiar with Rinnai, Navien, Triangle Tube, Lochinvar, Burnham and other boiler brands
  • Authorized Rinnai dealer with financing and free estimates on installations

Signs your boiler or radiant heat needs work

  • The boiler will not start or shuts down again and again
  • A fault code shows on the display
  • Radiators, baseboards or floors stay cold or heat unevenly
  • The system keeps losing pressure
  • You see water around the boiler
  • Banging, gurgling or whistling comes from the pipes
  • The boiler was not serviced before this heating season

Frequently Asked Questions

Do you do radiant heat repair in Marin and Sonoma County?

Yes. We diagnose the boiler, controls, circulators and heating zones behind a radiant system. Radiant heat can usually be repaired without replacing the flooring, as long as there is no deep slab leak or extensive damage. Tell us what you are seeing and we will explain the options.

How much does boiler replacement cost?

The answer depends on the boiler, your existing radiators, baseboards or radiant floors, and the venting and controls, so we do not quote a number without seeing the system. Replacement and installation estimates are free and written, and financing is available. Senior and veteran discounts take $250 or $200 off any install.

Do you offer boiler repair in Santa Rosa?

Yes. Our Santa Rosa and Petaluma offices serve Sonoma County, and our San Rafael office serves Marin. If your boiler will not start, loses pressure or leaves rooms cold, we diagnose the boiler and the system around it, then explain your repair options before work begins. Bring the model and serial number when you call.

Can a new boiler work with my existing radiant heating?

Yes. A new high-efficiency boiler can supply an established radiant system. Before recommending one, we check your existing radiators, baseboards or radiant floors, along with the venting and controls. Ask us about Rinnai, Navien, Triangle Tube, HTP, NTI, Lochinvar, Burnham, Crown, Peerless and Laars; service options depend on the model, its condition and parts availability.

Why is my boiler making banging, gurgling or whistling noises?

Noises like these can come from mineral buildup, pressure problems, trapped air or condensed water hitting the pipes. Because the cause varies, we check the boiler and the heating loop rather than guess. A yearly service before heating season is a good time to catch these problems early.
