The INTERNATIONAL COMFORT PRODUCTS MFHMA5X36L0BA is a Maratherm-branded residential fan coil unit rated at 3 tons of cooling capacity. It operates with R454B refrigerant, a lower-GWP A2L refrigerant increasingly specified in new residential and light-commercial split systems. The unit uses an ECM (electronically commutated motor) for the indoor blower and includes a factory-installed TXV (thermostatic expansion valve) for precise refrigerant metering. Licensed HVAC technicians install this unit as the indoor section of a split or packaged system, connecting it to a matched outdoor condensing unit or heat pump.
This fan coil is suited for residential and light-commercial applications where a ducted indoor air handler is required. The ECM blower motor improves part-load efficiency and allows for variable airflow staging when paired with compatible controls. The factory TXV eliminates the need for a field-installed metering device, reducing installation variables. The R454B refrigerant circuit requires compatible system components rated for A2L refrigerants per current AHRI and manufacturer guidelines.
Designed as an OEM-style indoor fan coil for ducted residential split systems using R454B refrigerant. Pair with a matched outdoor condensing unit or heat pump rated for R454B. Confirm system matchup through AHRI or manufacturer documentation before installation.
Installation must be performed by a licensed HVAC technician familiar with A2L refrigerant handling requirements, as R454B carries a mild flammability classification. Disconnect and lock out all electrical power before servicing or connecting the unit. Follow local mechanical codes and manufacturer guidelines for duct connections, condensate drain routing, and electrical wiring. Do not mix R454B with other refrigerants or use equipment not rated for A2L service.
