MSS is one of the few full-service mechanical contractors in Utah, which means our people aren’t boxed into one narrow specialty. Our teams work across HVAC, plumbing, boilers, controls, fabrication, and construction, all under one roof, giving technicians, fabricators, and project managers room to build a broader skill set instead of doing the same task on repeat. In the field, that means union-trained technicians and apprentices working hands-on with everything from rooftop HVAC units to industrial boiler systems. In the office, it means project managers, estimators, and support staff coordinating work that keeps some of Utah’s most demanding facilities running.
