A Fan Coil Unit (FCU) is a compact indoor device that consists of a heating or cooling coil and a fan to condition the air in a specific space. Unlike a large central air handler, FCUs are often used in Multi-Zone Systems to provide individual control for different rooms or offices. They are the core indoor components of most Ductless Mini Splits and can be mounted on the wall, floor, or hidden in the ceiling. Because they do not require extensive ductwork, they are highly efficient and easy to retrofit into older buildings. Our ACIq fan coils are designed with advanced filtration and variable-speed motors for maximum comfort. You can explore various styles, including Ceiling Cassettes, in our specialized collections. These units allow you to save money by only heating or cooling the rooms that are currently in use. They represent the peak of versatile, room-by-room climate management for modern homes.
