General Motors introduced air conditioning with their 1953 models. Initially the system included the underhood compressor and a trunk-mounted evaporator and fan. Consequently, the system was only available in closed sedans and coupes (no wagons or convertibles). The earliest set of controls that I've personally seen were in a 1956 Buick, which by then had all of the equipment installed under the hood with the air distribution in the instrument panel. However, at no place on the instrument panel did the words "air conditioning" appear. There were levers and switches for "heat" and "defrost" and.........you guessed it.......... "Frigidaire".
