Bahnson Mechanical Systems (BMS) traces its roots back to 1915 when incorporated as the Normalair Company to sell and manufacture a newly developed electric centrifugal humidifier to the textile industry. In 1929 the name was changed to the “The Bahnson Company” and today, Bahnson Mechanical Systems continues the rich legacy of the Bahnson name.

Today BMS is a major facility services provider offering a broad range of HVAC and full mechanical services to virtually every market segment within the U.S.
