Willis Carrier’s invention of modern air conditioning has been changing the way people live since 1902. Explore how his innovation helped launch entire industries, enabled new possibilities and continues to impact your life in ways far beyond keeping you cool and comfortable.
How Inventing the Air Conditioner Changed the World
Making Printing Possible
The first modern air-conditioning system wasn’t actually created to keep people cool. It was installed at Sackett & Wilhelms printing plant in Brooklyn to address summer humidity issues affecting the printing press. Installed in 1902, Carrier’s invention kept consistent temperature and humidity in the plant, enabling the printing press to operate year-round without issues.The Rise of Retail
In the 1920s, a series of iconic air-conditioning installations in department stores helped keep customers cool and comfortable even on the hottest days, contributing to rapid growth in the retail industry. First was the J.L. Hudson Company, Detroit's largest department store, which installed three, 195-ton centrifugal chillers.
Other sophisticated retailers in Seattle, Boston, Cincinnati, Dallas and New York City soon followed.
Crate & Barrel
"Crate & Barrel operates more than 170 stores across the United States. To maintain the optimal environment for showcasing its products, its stores require four times more energy for lighting than traditional stores."
SPAR Hungary
"SPAR Hungary operates over 550 retail food stores including more than 30 Spar International hypermarkets."
J.L. Hudson Company
"In 1924, Detroit's largest department store, installed three, 195-ton centrifugal chillers. Officially classified as comfort air conditioning, Willis Carrier noted, the installation was also designed "to meet an emergency as temperatures soared on basement bargain days—people fainted."
Preserving History
In places ranging from the Sistine Chapel to Mount Vernon, Carrier helps protect historical sites and artifacts so that they can be enjoyed by visitors for generations to come.
Sistine Chapel
"In the fall of 2014, Carrier installed an innovative heating, ventilating and air-conditioning (HVAC) solution at the Sistine Chapel, specially developed to help preserve Michelangelo’s masterpieces against deterioration caused by an increasing number of visitors."
Mount Vernon
"When it came time to preserve the historical residence, Mount Vernon, it seemed only natural that its curators turned to Carrier, the company founded by “The Father of Modern Air Conditioning."

Enabling Global Networks
"Data centers are full of servers and high-tech equipment that generate heat. To operate reliably and efficiently, each piece of equipment must be kept within a manufacturer-recommended range of room temperatures, generally from 16°C to 24°C (61°F to 75°F). That’s where Carrier® air conditioning comes in."Shanghai Futures Exchange Zhangjiang Data Center
"Shanghai, a financial and cultural center of China, is a powerful engine that helps fuel the rapid economic growth of the country – and Carrier is able to innovate as fast as one of the world’s largest cities can grow."Revolutionizing Healthcare
In 1914, the Allegheny General Hospital in Pittsburgh, Pennsylvania used a Carrier air conditioning system to establish the first incubator room, providing a comfortable environment for infants. Throughout the 20th century, Carrier would expand their reach in this market by air conditioning hospitals in Mexico City and Cairo, Egypt, and later in New York City, helping the Lenox Hill Hospital use a cold diffuser in its cryotherapy room.
By 1940, the American Medical Association's Council on Physical Therapy accepted Carrier room ventilators equipped with a pollen-type filter and authorized the use of the AMA seal.
