Hydronic heating service — even, efficient warmth from water, not forced air.

Hydronic systems heat your home with hot water — through radiant floors, baseboards, or radiators — for quiet, even, comfortable warmth. We service, repair, replace, and tune up the equipment that runs them across Sonoma County — boilers, pumps, valves, manifolds, and zones. (We keep existing radiant and baseboard systems running; we don’t install new radiant floor systems.)

Good to know

Hydronic heating questions, answered

What is hydronic heating?

Heating your home with hot water — through radiant floors, baseboards, or radiators — for quiet, even warmth instead of forced air.

My system has cold spots — can you fix it?

Usually yes. Cold spots are often trapped air or a struggling circulator pump. We diagnose and correct it.

Do you install new radiant floor systems?

No — we don’t install new radiant floor systems. But we service, repair, and replace the boilers, pumps, valves, and controls that run existing radiant and baseboard heat, and keep them tuned up.

Do you service the boiler too?

Yes — we service, repair, and replace the boiler and its controls, along with the rest of the hydronic system.

Cold spots or no heat? Let’s get it running right.
