Gas Boiler Repair & Installation in Sausalito, CA

A condensing boiler pulls extra heat from the exhaust, so it has a condensate drain, sealed venting and more sensors. Faults often trace to the drain, vent, igniter or a sensor. We check those first and read the fault code. Parts support depends on brand and model, and we tell you plainly what is available.

Yes. Lochinvar, NTI and Navien are all brands we service, and so are Rinnai, Triangle Tube, HTP, U.S. Boiler, Crown, Peerless and Laars. Give us the model and serial number when you book. We will tell you whether a repair is practical before you decide on anything larger.

We confirm where the boiler will go, plan the vent and condensate drain, size the unit to the house and check how it connects to your radiators, baseboards or radiant floors. Then we set up the controls. You get a free estimate on a replacement, and financing is available.

Yes. Radiant floor heating installation depends on the floor construction, the heat the rooms need, available space and how the system connects to the boiler. Tell us about the project, and we will explain the design and the estimate before work begins.

Each level is often its own zone. A stuck zone valve, a weak circulator, trapped air or a thermostat fault can leave one zone cold while the boiler runs normally. A bigger boiler does not fix those problems. We find the failed part and repair it.
