Air conditioning was one of those problems that have been around for over thousands of years. Herbert Hoover was the first president to install air conditioning into the White House in 1929. Because of the size and cost, only wealthy people with large homes could afford air conditioners. In 1939, the automobile manufacturer Packard began installing air conditioning systems (called “weather conditioners”) in its vehicles. That’s the equivalent of 600 air conditioners every minute and 3,600 air conditioners every hour.
