Packard was the first car company to offer air conditioning as an option in its cars. Packard introduced its "Climate Control" system in 1939, which allowed drivers to adjust the temperature and airflow inside the car. The system used a compressor and evaporator unit mounted under the hood, and was controlled by a dial on the dashboard. Packard's air conditioning system was ahead of its time, and it was not widely adopted by other car companies until the 1950s.
