We are proud of Bahnson’s 100+ year history as a mechanical engineering contractor. The Bahnson family began by selling industrial humidifiers to the textile industry in 1915, and steadily grew the company through the middle of the century.  

In the 1970s and ‘80s, they were a major supplier of air conditioning systems to the utility industry including nuclear power plants. As the 1900s became the 2000s, the company continued to thrive under Swedish and Swiss ownership with offerings in cleanroom technology and the industrial HVAC market.

Advancement in technology and evolution in the market, led to our independent operations incorporating in 1991, as Bahnson, Inc. Today, our team continues to make history of its own solving our clients’ mechanical engineering challenges.

Our customers work in textiles, manufacturing, utilities, pharmaceuticals, biotech and numerous other industries.

 As a subsidiary of EMCOR Group, Inc., we contribute to a corporation consistently named one of the “World’s Most Admired” in the Engineering and Construction Industry by Fortune®.   Throughout this century of experience, our constant has been great people that operate with a spirit of service, innovation and humility.
