Willis Carrier is credited with inventing modern air conditioning in 1902. In 1915, Carrier and six other engineers pooled $32,600 to form the Carrier Engineering Corporation. They purchased their first factory in 1920, in Newark, New Jersey.
The 1986 edition of Dr. John Watt's Evaporative Air Conditioning Handbook identifies the origins for modern American evaporative cooling as either from the East Coast or Southwest. In the early 1900s, air washers were invented in the East and air coolers were developed in Southwest (Arizona and California). The air washers passed air through water spray, which cleaned and cooled the air in textile mills and factories in New England and the Southern coastline.
