ACCO Engineered Systems was founded in 1934 as Air Conditioning Company (AACO) at a time when air conditioning was a rare luxury. The company first worked as a refrigeration products distributor for General Electric. Following WWII it became a major distributor of Carrier Corporation's air conditioning products. In the early 1950s AACO shifted from being an air conditioning distributor to become a corporation.
