ACCO History

ACCO Engineered Systems was founded in 1934 as Air Conditioning Company (ACCO), a proprietorship, by Ira Prentiss Fulmor at 1005 Santa Fe Street, Los Angeles. The former name of the company was chosen to indicate what the company did because few people knew about air conditioning. In 1949, the business moved from downtown Los Angeles to Glendale at its present address. In 1950, ACCO transformed from an air conditioning distributor to become an independent corporation. Kenneth D. Simon was President from 1969 to 1980, then handing the reins to Theodore M. Seidman who led ACCO from 1981 to 1989. In 1991 John Aversano became President, and remains at the helm today.

Over the years ACCO has expanded its leadership role in the design, installation, and service of industrial, commercial, high-rise, residential, and institutional air conditioning, heating, ventilation, plumbing, process piping, electrical and DDC control systems. ACCO’s name was changed in 2002 to ACCO Engineered Systems to better reflect the many aspects of its business. A national trade publication recently ranked ACCO among the 5 largest heating, ventilating, and air conditioning contractors in the nation. The company has an average of 1,725 employees. ACCO’s offices and manufacturing facilities occupy more than 20 acres, spanning 13 locations.

ACCO’s mechanical systems occupy facilities in a wide variety of industries, including commercial office space, biopharmaceutical R&D, semi-conductor, micro-electronics, medical/healthcare centers, manufacturing plants, entertainment, retail, telecommunications, education, data centers, and high rise residential.

ACCO has completed work in Arizona, California, Florida, Hawaii, Illinois, Louisiana, Maryland, Michigan, Nevada, New Jersey, New Mexico, Oregon, Tennessee, Texas, Utah, Virginia, Washington, Washington D.C., and Mexico.
