History of Innovation

Carrier has been innovating heating and cooling solutions since 1902—when our founder, Willis Carrier, developed the first modern air conditioning system and changed the way we work and live.

Launching an Industry

On July 17, 1902, young research engineer Willis Carrier designed the first modern air-conditioning system after realizing that water could be used to remove moisture from air. Little did he know that this invention would lead to his launch of a company and would create an entire industry essential to global productivity and personal comfort. The first system included chilled coils, fans, and ducts to control air temperature and maintain constant humidity. He received a patent for the design in 1904 and went on to start the Carrier Engineering Corporation in 1915.

Setting the Standard

Developed in 1914, Willis Carrier’s Rational Psychrometric Formulae merged science with his design of air conditioning systems, becoming an essential tool for generations of engineers. Today, it remains the basis of HVAC designs.

Influential Innovation

Invented in 1922, Willis Carrier’s single most influential innovation was the centrifugal refrigeration machine, more commonly known as a chiller. This extended the reach of air conditioning beyond commercial applications like factories and mills, and brought it into the systems we see in homes today.

Taking the LEED®

We've continued Willis Carrier’s innovations and environmental consciousness. In 2001, Carrier’s Monterrey Commercial plant became the first industrial facility in the global HVAC industry to be Leadership in Energy and Environmental Design (LEED®) Gold Certified.

Embracing Diversity

In 1917, before women were allowed to vote in the United States, Willis Carrier hired Margaret Ingels as the first woman air-conditioning engineer in the country. She later served on President Herbert Hoover’s Conference on Home Building and Home Ownership.
