What United Building Solutions does
United Building Solutions (UBS) is a Pennsauken, New Jersey-based commercial mechanical services platform that provides HVAC, building controls, plumbing, and custom sheet metal solutions to mission-critical, multi-site facilities across the United States. The company serves six primary verticals — Government, Education, Healthcare, Data Centers, Hospitality, and Pharma — through an owner-direct go-to-market model that emphasizes single-source provider relationships and direct contracts with facility owners rather than general contractor intermediation. UBS's service offering combines recurring service and maintenance contracts, building controls integration, building analytics for energy and operational optimization, and project work including system design, retrofits, and new installations. Over 90% of revenue is recurring and more than 50% derives from Service Owner Direct relationships, supported by an average customer tenure of approximately 9 years and a contract retention rate above 90%.
The company traces its origins to Lor-Mar, founded in 1997 in Pennsauken, and was acquired by Crescendo Capital Partners and Newspring in 2012, followed by the 2014 acquisitions of Unitemp, Mechanical Degrees, and A&B to add controls expertise and Mid-Atlantic scale. UBS rebranded from Lor-Mar Holdings in 2023 to reflect its multi-regional platform strategy. In February 2025, AE Industrial Partners invested to position UBS as a national commercial HVAC services platform, simultaneously partnering with Total Comfort Solutions for Southeast market entry. Subsequent add-on acquisitions of DFW Mechanical Group (January 2025, Texas/Oklahoma/Georgia/Florida) and McCarl's Services (April 2026, Western Pennsylvania/Ohio/West Virginia) expanded the platform to 11 markets spanning the Northeast, Midwest, Southeast, and South-Central United States. UBS retains the operating-company brands, local management, and union-trained technician base of its acquired entities, with shared corporate capabilities in engineering, controls, and analytics layered on top.
