MECHANICAL SERVICE & SYSTEMS, LLC

Mechanical Service & Systems Inc. specializes in the installation, repair, and maintenance of complex heating, ventilation, and air conditioning systems, with deep expertise in commercial and federal facility boiler systems. The contractor delivers turnkey solutions for high-pressure steam and hydronic systems, including the procurement and installation of ASME-certified expansion tanks, control modules, and integrated HVAC components. Their technical proficiency extends to precision system diagnostics, code-compliant retrofitting, and the integration of building automation controls for mission-critical infrastructure, particularly in environments requiring uninterrupted thermal performance. A key differentiator is their ability to execute technically demanding boiler and heat exchanger projects under strict federal compliance standards, often involving legacy system upgrades with minimal operational disruption. The company has established a consistent presence with the Department of Veterans Affairs, where they provide critical boiler repair and maintenance services to ensure continuous heating for veteran healthcare facilities. They also serve the Department of the Interior with specialized HVAC control system installations for historic and protected sites like Dinosaur National Monument, demonstrating an understanding of preservation-sensitive infrastructure needs. Additionally, their work with the Department of Transportation highlights experience in industrial-grade thermal system components, including ASME pressure vessel installations at federal transportation maintenance centers. Their primary focus is on NAICS 238220, reflecting deep specialization in plumbing, heating, and air-conditioning contracting for government facilities, with supplementary capability in NAICS 332410 for manufacturing and installing power boilers and heat exchangers. This positions them as a hybrid contractor-manufacturer, uniquely equipped to handle both system design and on-site implementation of high-capacity thermal equipment. Mechanical Service & Systems Inc. is a small business structured as a 2L entity, headquartered in Salt Lake City, Utah, with a regional footprint centered on federal installations across the Western U.S. While they currently hold no formal government certifications, their proven track record in delivering complex, code-compliant thermal systems for federal agencies underscores their reliability and technical credibility in the public sector market.
