Commercial Boilers & Water Heaters

Commercial and industrial boiler and water heater installation, commissioning, and service throughout Santa Clara County, Santa Cruz County, Alameda County, Contra Costa County, Monterey County, and San Francisco. Golden Gate Mechanical, Inc. — C-20 Licensed, CSLB #646854.

Golden Gate Mechanical, Inc. provides full-service commercial and industrial boiler and water heater services throughout the San Francisco Bay Area. What sets us apart from most boiler service companies is our multi-trade licensing — holding Class B, C-16, C-20, and C-10 licenses means we can address every aspect of a boiler or water heater problem under one contractor. Most service companies can only touch the equipment itself. By contrast, Golden Gate Mechanical, Inc. can self-perform the mechanical work, electrical connections, gas piping, controls integration, fire protection, and backflow protection all in-house. As a result, problems get diagnosed and resolved faster, there are no delays waiting for other trades, and building owners have a single point of accountability for the entire system.

Our services

New installation

Golden Gate Mechanical, Inc. handles complete boiler and water heater installations — from equipment selection and rigging through gas piping, electrical connections, controls integration, and full commissioning. We coordinate all associated trades and ensure your system is installed to code and operating at rated efficiency before project completion.

In addition, we evaluate your existing system and recommend right-sized replacement equipment that meets your current heating and hot water demands while maximizing energy efficiency.

Preventative maintenance

Regular maintenance is essential for safe, efficient boiler and water heater operation. Our maintenance programs cover burner tuning, heat exchanger inspection and cleaning, safety control testing, anode rod inspection, flue gas analysis, and full system performance documentation. Consequently, clients on maintenance programs experience fewer breakdowns and lower fuel costs over time.

Our technicians diagnose and resolve burner failures, heat exchanger issues, controls problems, leaks, and all other mechanical and electrical faults. Furthermore, we respond promptly to emergency calls to minimize downtime in occupied facilities.

Hydronic system service

Beyond the boiler itself, we service all associated hydronic system components including pumps, expansion tanks, air separators, mixing valves, zone controls, and all associated piping. As a result, your entire heating system operates as a coordinated and efficient whole.

Controls and upgrades

Modern boiler and water heater controls can dramatically improve system efficiency and reduce operating costs. Golden Gate Mechanical, Inc. evaluates existing equipment and recommends targeted upgrades that deliver measurable energy savings and improved system reliability for building owners and facility managers.
