Carrier is a global provider of climate and energy solutions, tracing its origins to 1902 when Willis Carrier invented modern air conditioning. Today the company employs approximately 48,000 people and operates across roughly 160 countries, organised into four global business segments spanning residential, commercial, and logistics applications.
The company's work covers a broad technical spectrum, including heating, ventilation and air conditioning (HVAC), indoor air quality, energy efficiency, building automation, home heat pump technology, and cold chain logistics. Its commercial building automation systems are designed to improve energy performance and air quality in large buildings, while its transport refrigeration capabilities support the preservation of vaccines, food and medicine in transit.
Carrier frames its engineering work around reducing environmental impact - developing technologies such as low-emissions heat pumps and more efficient refrigeration systems. The company describes its teams as focused on continuous development of solutions that improve indoor environments and reduce energy consumption across both residential and commercial settings.
