From high-efficiency replacements to annual service on the boiler you already own, we handle every step with the steady care of a specialist who's been at it for 20+ years.
A boiler is the heart of a hydronic home, and the wrong install can cost you for years. We help you choose, size, and install the right unit for your home, then maintain it so it actually delivers what the manufacturer promises.
Boilers often give warning signs before they fail. These are the signs most frequently reported by homeowners in the Bay Area.
Older boilers run far less efficiently than modern condensing units, even when they're still working.
A steady rise in your gas bill, even with the same usage, often points to a boiler losing efficiency.
Some rooms warm up, others stay cold. Often a circulator, zone valve, or pressure issue at the boiler.
A specialized team that will take care of your home as if it were their own.
We evaluate your existing system, your home, and your goals before recommending anything.
You get options, trade-offs, and an honest cost. No upsells, no pressure.

For most Bay Area homes with hydronic heating, yes. Modern condensing boilers run at 90-95% efficiency compared to 70-80% on older units, and many installs qualify for utility rebates. Over a 15-year lifespan the savings usually outweigh the upgrade cost.
Costs depend on the size of your home, the model, venting requirements, and the condition of the existing piping. A straightforward replacement can range from several thousand dollars upward. Call us for an estimate.
Once a year, ideally before the heating season. Annual service includes pressure checks, safety control tests, expansion tank inspection, and a flush if needed. It's the single best way to extend the life of the unit.
It comes down to how much of the fuel a boiler turns into usable heat, measured by its AFUE rating. A condensing boiler pulls extra heat out of the exhaust gases that older, non-condensing units sent straight up the flue. The result is more warmth from the same fuel and a lower gas bill.
Often, yes. We diagnose the actual cause before recommending replacement, and we'll be honest about whether a repair is the right call or whether a replacement will save you money over time.
