United Building Solutions Acquires DFW Mechanical Group

Acquisition continues expansion across Southeast and South-Central United States

CONSHOHOCKEN, Pa.--(BUSINESS WIRE)--United Building Solutions (“UBS”), a leading provider of heating, ventilation, and air conditioning (“HVAC”) services across the United States, today announced that it has acquired DFW Mechanical Group (“DFW” or the “Company”), a full-service commercial and industrial mechanical contractor serving clients across Texas, Oklahoma, Georgia, and Florida.

“We’re pleased to welcome DFW Mechanical into our expanding network of premier HVAC service providers,” said David Leathers, CEO of United Building Solutions. “This acquisition further diversifies our array of services and enables us to reach the key markets in the Southern US that are experiencing heightened demand for specialized building management solutions.”

Headquartered in Wylie, Texas, DFW delivers comprehensive commercial HVAC solutions, offering a full range of services including plumbing, heating, and piping. The Company will operate as a UBS division under the continued leadership of President Brett Thomas, a seasoned executive with more than three decades of industry experience.

“United Building Solutions is a respected HVAC services provider known for its advanced technical expertise,” said Brett Thomas. “By joining forces, we can expand our market reach and leverage our combined resources to serve a broader range of customers while upholding our commitment to delivering high-quality, professional services.”

This is UBS’ second add-on transaction following investment into the company by AE Industrial Partners in February 2025, and its establishment as a national commercial HVAC services platform with the concurrent acquisition of North Florida-based HVAC solutions business Total Comfort Solutions. With the acquisition of DFW, UBS’ footprint now extends across the Southeast and South-Central United States in addition to its existing Northeastern United States coverage.

“Building owners and operators are increasingly recognizing the critical role HVAC systems play in preserving the integrity and performance of their facilities while improving efficiency,” added Bryan McElwee, Partner at AE Industrial. “The acquisition of DFW positions UBS as a comprehensive, nationally scaled commercial platform that is poised to capitalize on these industry tailwinds.”
