Same-Day DiagnosisResidential • CommercialCalifornia Lic. #1091355
We troubleshoot ignition, circulator, control, combustion, and pressure faults on modern and legacy equipment.
We replace aging cast-iron, atmospheric, and failed condensing units with properly sized, code-compliant equipment.
We service older non-condensing and hydronic heating systems, including atmospheric boilers, vintage cast-iron equipment, outdated controls, and aging components.
Annual service plus targeted upgrades to pumps, controls, expansion tanks, and near-boiler piping.
Diagnostics, maintenance, flushing, warranty assistance, and hydronic integration on NHB, NFB, and NCB systems — including older Navien generations still running across the Bay Area.
We troubleshoot complete hydronic systems — not just the boiler itself. Our process includes combustion analysis, flow and pressure diagnostics, circulator evaluation, expansion tank checks, temperature differential testing, and control verification to identify the real cause of system problems.
We design and install single-boiler and multi-boiler cascade replacements for residential and light commercial applications. Our team helps customers modernize outdated mechanical systems with properly sized equipment, advanced controls, zoning upgrades, and efficient hydronic layouts.
Our engineers work with both modern high-efficiency condensing boilers and older hydronic heating systems, including cast-iron and atmospheric equipment still operating throughout the Bay Area. We diagnose, repair, modernize, and integrate systems that many contractors refuse to service.
Our team brings extensive European hydronic experience to ongoing service work — circulator upgrades, control tune-ups, mixing-assembly retrofits, and annual maintenance that keeps the entire loop balanced. This background helps us approach upgrades and maintenance with a deeper engineering perspective.
An honest evaluation of repair versus replacement — not a default sales pitch for new equipment.
Hydronic heat is silent, even, and dust-free when the entire loop is balanced and the controls are tuned.
Correct piping, water quality, and combustion setup separate a 7-year boiler from a 20-year boiler.
Combustion, venting, and gas work are life-safety systems. We test, document, and commission every install.
