Who invented the car air conditioner?

While several people contributed to the development of car air conditioning, Willis Carrier is not directly credited with inventing it for cars. He invented the first modern electrical air conditioning system in 1902, laying the groundwork for the technology.

The first practical car air conditioning system is generally attributed to Packard in 1939, though they didn't invent it from scratch. They collaborated with other companies to integrate an existing technology into a car. It was a cumbersome and expensive system, but it marked the beginning of widespread adoption. No single inventor can be definitively named.
