Pioneering Air Conditioning Since 1902
Brand history, product range & what we stock
Carrier traces its origins to 1902, when engineer Willis H. Carrier invented the world's first modern air conditioning system in Brooklyn, New York. That breakthrough launched what is now the world's largest HVAC manufacturer, operating in over 160 countries and serving everything from single-family homes to hospitals, data centers, and cold-chain logistics facilities. Carrier's engineering legacy is embedded in every component — from ultra-quiet scroll compressors to modulating gas valves and communicating Infinity® controls.

Common questions about Carrier OEM replacement parts
OEM parts are manufactured by Carrier to exact factory specifications, ensuring correct fit, rated performance, and warranty compliance. Aftermarket substitutes are third-party copies that may void your Carrier equipment warranty and commonly have shorter service life ratings. For any Carrier system under warranty, only OEM parts maintain manufacturer coverage per Carrier's published terms.
