About Bryant
Bryant Heating & Cooling traces its roots to Bryant Heater Co., a company founded by Charles Bryant and based in Indianapolis, Indiana. The brand became part of Carrier Global Corporation in 1955, when Carrier merged with Affiliated Gas Equipment, Inc., the parent company that owned Bryant Heater Co., along with Day & Night Water Heater Co. and Payne Furnace & Supply Co. That acquisition significantly expanded Carrier's residential heating product lines.
Carrier itself was founded on June 26, 1915, in Syracuse, New York, by Willis Carrier, the inventor of modern air conditioning. Carrier was acquired by United Technologies Corporation in 1979. In April 2020, Carrier was spun off from United Technologies as an independent publicly traded corporation on the New York Stock Exchange under the ticker symbol CARR. As of 2025, Carrier reported revenue of $21.7 billion and employed approximately 47,000 people worldwide.
