Willis Carrier: The Father of the Air Conditioner. The first modern air conditioner was invented in 1902 by Willis Haviland Carrier, a skilled engineer who began experimenting with the laws of humidity control to solve an application problem at a printing plant in Brooklyn, NY.
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.
