110 Years of Cool
The Birth of Modern Air Conditioning
While not quite a national holiday, many homeowners would agree that it almost should be. July 17 is the day air conditioning was invented and this year marks its 110th anniversary.
Willis H. Carrier is credited for inventing the air conditioner which he utilized at a printing plant in Brooklyn, New York to keep ink impressions on paper on very hot days. Since that historical day he obtained over 80 patents on devices that controlled air temperature, ventilation, indoor air and humidity.
