Gas Boiler, Hydronic & Radiant Floor Heating Repair in Mill Valley, CA

Yes. We service Navien boilers, along with Lochinvar, NTI, Rinnai, Triangle Tube, HTP, U.S. Boiler, Crown, Peerless and Laars. Give us the model number, serial number and any error code, and we will check parts availability and tell you whether repair is practical.

In many cases, yes. Lockouts come from ignition faults, a dirty flame sensor, low water pressure, a blocked condensate drain or venting problems. We read the code, test each possibility and explain the repair. If you smell gas, leave the house and call your gas utility first.

Yes. We repair radiant floor systems and the boilers, pumps, manifolds and zone valves behind them. A cold floor is often a control, air or valve problem rather than a failed boiler, so we diagnose before recommending replacement. If the tubing is leaking, we explain the options first.

Yes. We size the boiler to the home’s heating needs, match it to your radiators, baseboards or floor loops, and plan the vent and condensate drain. Replacement estimates are free, and financing is available. Ask about our senior and veteran discounts when you book.
