A fan coil unit (FCU) is a device consisting of a heat exchanger (coil) and a fan. The heat exchanger coils are typically made of copper or aluminum and are either finned or unfinned. The fan is used to circulate air across the coil, which can either heat or cool the air depending on the type of fluid circulating through the coil.

FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings. They are often used in conjunction with ductless split air conditioning systems, which provide the chilled or heated water to the FCUs.
