If your gas boiler has stopped heating, boiler repair in Santa Rosa begins with finding out why, not with a sales pitch. We test the boiler, then the pumps, zone valves and thermostats behind it, and we tell you what failed before any work begins. Our Santa Rosa office handles the call.

Boiler installation and boiler replacement in Santa Rosa get the same care. We size the new boiler to the house, check that the existing radiators, baseboards or radiant floors will work with it, and plan venting and controls. Replacements come with a free estimate, financing is available and senior and veteran discounts apply.

Boiler maintenance is the simplest way to avoid a cold-morning breakdown. It is also when we catch slow zones and small leaks. We are family-owned, have served Marin and Sonoma County for over 40 years, and we explain every repair or replacement in plain terms. Radiant heat repair and installation are part of the same service, and so is commercial boiler work: offices, shops and small apartment buildings in Santa Rosa with hydronic heat get the same diagnosis-first service.

Why Santa Rosa homeowners call us before replacing

We would rather repair a boiler that still has years in it than sell you a new one. When replacement is right, we plan it properly.

  • Fault-finding on the boiler, pumps, zone valves and thermostats before any replacement is proposed.
  • The problem and the repair options explained before work starts.
  • Replacement sized to your house, with venting and controls planned in.
  • Commercial boiler service for Santa Rosa businesses and multi-unit buildings, not just homes.
  • Family-owned since 1986 and served from our Santa Rosa office.
  • Financing, plus a senior discount ($250 off an install, $50 off a repair) and a veteran discount ($200 off an install, $50 off a repair).

Signs to call about your Santa Rosa boiler

  • The thermostat calls for heat but nothing happens at the boiler.
  • Only one zone, or one level of the house, gets warm.
  • The boiler starts, runs a short time and shuts off, over and over.
  • Pressure keeps falling, or you find a drip at the boiler or a joint.
  • You hear banging or whistling when the burner fires.
  • A radiant floor is lukewarm or cold in one room.

Frequently Asked Questions

How much does boiler repair cost in Santa Rosa?

It depends on the fault, the boiler model, parts and how easy the equipment is to reach. A pump or zone valve is a different job from a failed heat exchanger. We diagnose first, then explain the options and cost before work begins. Senior and veteran customers get $50 off any repair.

What does a new boiler cost, and do you give estimates?

The price depends on the boiler, the size of the home, the venting and the controls, so we do not quote a number without seeing the system. We give free estimates on replacements and can explain financing. Senior customers save $250 and veterans save $200 on any install.

Why is my boiler running but one zone is cold?

A cold zone usually points past the burner: a stuck zone valve, a failed zone circulator, trapped air or a thermostat problem. If the boiler runs fine and the zone does not, we trace the circuit instead of replacing the boiler. Low pressure can cause the same symptom.

Do you offer boiler maintenance in Santa Rosa?

Yes. We service gas boilers and the zones, valves and pumps around them. A visit before the cold months is the best time to deal with leaks, slow zones, pressure changes and fault codes. Tell us the make and model when you call.

Do you repair radiant heat in Santa Rosa?

Yes. We repair and install radiant floor heating, and we also service the radiators and baseboard systems that run off the same boiler. We usually start with the boiler, pump, valves and controls. If the problem is in the floor itself, we go over the options with you before any work begins.

Do you service commercial boilers in Santa Rosa?

Yes. We repair, maintain and replace boilers in offices, retail spaces and small apartment buildings in Santa Rosa, as well as homes. Commercial systems get the same approach: we find the fault in the boiler, pumps, zone valves or controls first, then explain the options before any work begins.
