Comfort Systems USA, Inc., a leading provider of commercial, industrial and institutional HVAC services, today announced that it has acquired Acorn Industrial, Inc. Raleigh, NC, and Dillingham & Smith Mechanical and Sheet Metal Contractors, LLC, Nashville, TN.

The company also announced that it has recently added smaller operations to existing Comfort Systems USA operations in Kentucky, Montana, and upstate New York.

Acorn specializes in complicated new and retrofit construction projects, including work for educational, institutional and industrial clients throughout the Raleigh/Durham area.

Dillingham specializes in commercial service and system retrofits, and residential system service and installation. It has 76 locations in 72 cities across the U.S. Its specialties include building automation, energy services, and Design/Build or Plan & Spec construction.

Comfort System sources say the new "tuck-in" operations bring strategic additions of new capabilities and geographies to three perennially successful existing locations. Taken together, these new companies reported revenues in 2009 of approximately $45 million at profitability levels that are expected to be roughly equivalent to those generally earned by Comfort Systems USA, Inc.

"We're extremely pleased to bring Acorn Industrial and Dillingham & Smith into the Comfort Systems USA family of companies," says Bill Murdy, Comfort Systems USA's CEO. "We're confident that their strong management teams and employees will be immediate contributors to our reputation and to our continuing operations. Together with the solid new tuck-in operations, these new partners have attributes and strengths that will help us to improve locally, regionally and nationally. Each of these companies has a proud history, and each provides us with a partner in a geography that we feel is strategic for future growth."
