Icp MR5H5S48AKAAA Heat Pump 15 SEER2 R-454B

Product Description

The INTERNATIONAL COMFORT PRODUCTS MR5H5S48AKAAA is a single-stage residential heat pump operating at 15 SEER2 efficiency and using R-454B refrigerant. Part of the Maratherm product line, this unit is designed for split-system heating and cooling applications where updated low-GWP refrigerant compliance is required. The single-stage compressor delivers consistent capacity output across a wide range of conditions. At 15 SEER2, the unit meets current federal minimum efficiency standards for heat pump equipment. Licensed HVAC technicians handle installation, startup, and refrigerant handling for this class of equipment.

The MR5H5S48AKAAA is suited for residential split-system installations where an outdoor condensing heat pump unit is paired with a compatible air handler or furnace coil. The use of R-454B refrigerant positions this unit in compliance with current and near-term refrigerant transition requirements. Single-stage operation makes it appropriate for applications where variable-capacity control is not required and straightforward thermostat integration is preferred.
