Peterson Mechanical provides mechanical construction services to the greater San Francisco Bay Area. Our work includes HVAC installations, plumbing systems, process piping and commercial refrigeration. We’ve met the specialized needs of laboratories, tech buildings, wineries, hospitals and high rises. Founded in 1915 in Sonoma, CA, where we’re still headquartered, Peterson has always adopted the most recent technologies. Our engineers use the latest 3D drafting (CAD), computer-aided manufacturing (CAM) and building information modeling (BIM) systems. Our team of professionals can work with a client from initial planning to project completion.
