A fan coil unit (FCU) is a device that uses a coil and a fan to heat or cool a room without connecting to ductwork. Indoor air moves over the coil, which heats or cools the air before pushing it back out into the room. FCUs can be less expensive to install than ducted systems, and are available in ceiling, floor-mounted and freestanding configurations.
As an alternative to FCUs, mini-split systems offer similar installation ease and flexibility, and can provide greater comfort and energy efficiency. Lennox® mini-split heat pumps feature efficiency ratings of 22 SEER and higher, indoor sound levels as low as 26 decibels, and inverter technology that eliminates the typical starts and stops of conventional systems.
