Our History

Founded in 1976, Bay City Boiler sells, installs, retrofits, rents, repairs, and maintains boiler equipment for commercial and industrial customers across Northern and Central California. We offer world-class equipment from leading manufacturers, including steam and hydronic boilers, domestic hot water heaters, boiler burners, thermal fluid heaters, and ancillary and customary equipment.

Our highly competent and committed workforce ensures that your project, from the design phase through installation, is executed thoughtfully and thoroughly. For 24/7 emergency service, skilled technicians are on call to respond quickly. We also offer a comprehensive maintenance program to ensure your boiler is always working in top shape. This prevents you from sudden shutdowns, surprises, and loss of revenue.

As a leading boiler company, Bay City Boiler has also exceeded the minimum required safety standards by securing the licensing, professional associations, and insurance coverage that many other boiler businesses do not. We service all commercial and industrial accounts, including brewery, distillery, and winery industry, the food processing industry, hospitals and healthcare, and mechanical contractors. Our expert staff is on hand to assist you with your next boiler project or emergency.


When choosing a boiler service company to service your equipment, supply you with parts, or assist you in deciding on the boiler system that’s right for you, it’s important to check credentials to make sure your provider has the necessary training and protection to operate safely in your facility and provide you with the right advice. As your trusted expert, Bay City Boilers has gone well beyond the minimum required protection by securing the licensing, professional affiliations, and insurances many other boiler companies skip.
