Is there anything more wonderful that air conditioning? It literally changed the way we live and work. On really hot days this modern miracle can save hundreds of lives in just one city, by lessening incidences of heat stroke.
For this relief, we can thank Willis Carrier, who in the depths of winter in 1906 received a patent for what he called an “apparatus for treating air,” according to the U.S. Census Bureau.
Carrier launched his own company 102 years ago this month, and the Carrier name is still prominent among air-conditioning manufacturers.
The invention did not come into widespread use until after World War II. Even by 1965, only 10 percent of homes in the United States were equipped, and just 2.8 million window air conditioners were manufactured that year.
Today, 93 percent of all new, single-family houses in the United States are air-conditioned.
