Heritage Holding Acquires Nashville Sheet Metal, a Union Fabrication Shop

What happened

Heritage Holding, a Boston private equity firm, has acquired Nashville Sheet Metal, LLC, a sheet metal contractor based in Nashville, Tennessee. The completed sale was announced on November 10, 2026. Financial terms were not disclosed.

The seller

Nashville Sheet Metal was founded in 2003 and provides sheet metal services to commercial and industrial customers throughout Tennessee and the greater Mid-South. Its work covers HVAC ductwork, custom design, specialty component fabrication, and installation. The company operates a full-service union fabrication shop in Nashville.

On the commercial side, it fabricates and installs ductwork, fire dampers, and kitchen hoods for buildings such as schools and hospitals. Its industrial work runs to exhaust stacks, dust collectors, platforms, and specialty stainless steel for plants in automotive, tire, aluminum extrusion, and food production.

Dexter Cross is the company's president. He joined Nashville Sheet Metal in August 2014 as an estimator and project manager, after earning a degree in manufacturing engineering technology from Tennessee Tech. "We look forward to working with Heritage Holding as we continue serving our customers and investing in our people and capabilities," Cross said in the announcement.

The buyer

Heritage Holding was founded in 2015 and has completed more than 60 acquisitions since then. It has $550 million of committed capital and a core focus on founder-owned essential business-to-business services companies, including HVAC. Its other holdings run from IT services and internet providers to healthcare, engineering, and utility services. Heritage says its "committed capital from family offices allows us to make decisions that are in the best interest of companies in the long run."

Its HVAC holdings include Airco in Troy, Illinois, along with mechanical contractors in New England and the Pacific Northwest.

Heritage's July deal in Central New York

Four months earlier, on July 9, 2026, Heritage announced the acquisition of Airside Technology Corporation, a commercial and industrial HVAC contractor in East Syracuse, New York. Airside was founded in 1984 and runs a union workforce. It provides controls and pipe fitting, and fabricates its own sheet metal in an in-house automated facility. Coverage of that deal said Heritage's mechanical platform was operating under four distinct brands at the time. Terms of that deal were not disclosed either.

What this means for HVAC and sheet metal owners
