We are tracking United Building Solutions' add-on acquisition of McCarl's Services, based in Cranberry Township, western Pennsylvania, announced April 23, 2026. Deal value undisclosed; no multiple disclosed. [CONFIRMED]
McCarl's, founded in 1946, is a commercial and industrial HVACR specialist now operating as a UBS division under president Mike McCarl, and the deal extends coverage into Ohio and West Virginia.
This is UBS's third add-on since AE Industrial Partners formed the platform in February 2025, growing it from three Mid-Atlantic markets to eleven.
PwC Advisory advised AE Industrial, while Three Sixty Seven Advisors advised McCarl's.
Our data indicates a notable adjacency move. AE Industrial's core expertise sits in national security, aerospace, and industrial, so a commercial HVAC platform represents a deliberate step into building services. We read the steady add-on pace as evidence the thesis is holding, with an eighty-year-old contractor lending operating credibility to a still-young platform in the sector.
