These recessed ceiling fan coils are designed for use with today's higher efficiency split-system condensing units and heat pumps. High efficiency ECM type motors are standard in all HXX series fan coils.

The base HXX fan coil is an open blower type (non-enclosed)fan coil. It is also available with either a field or factory installed enclosure, with both options including your choice of either a louvered or solid ceiling panel. For HXX fan coils factory installed within an enclosure, add "-C" after the kW in the model number. For instance, ordering model 19HXX5-C R410 TXV, will include an 19HXX5 R410 TXV fan coil factory installed in a number 9EHX01 enclosure and your choice of either a solid or louvered panel. A "cap kit" is also available when the HXX is installed above a ceiling, rather than recessed.

Compatible outdoor units: First Co's customer is ultimately responsible for confirming which fan coil models are compatible with selected outdoor units. To determine certified indoor/outdoor matches, go to or contact the factory.
