Icp H5H8T48AKAAA Heat Pump 18 SEER2 2-stage R454B

Product Description

The INTERNATIONAL COMFORT PRODUCTS H5H8T48AKAAA is a two-stage, 18 SEER2 residential heat pump designed to operate with R454B refrigerant. As a deluxe-class unit in the Heil H5H8T series, it delivers both cooling and heating from a single outdoor condensing unit. The two-stage compressor modulates capacity to match building load, reducing short-cycling and improving indoor comfort and humidity control. Cooling airflow is rated at 1,120 CFM, and heating airflow reaches 4,781 CFM, making this unit well suited for ducted split systems in residential applications. Licensed HVAC technicians handle installation and commissioning of this equipment.

The H5H8T48AKAAA is intended for residential ducted split-system applications where a high-efficiency heat pump is specified. The 18 SEER2 efficiency rating meets current Department of Energy regional efficiency minimums and positions this unit for energy-conscious new construction and replacement projects. Its use of R454B refrigerant aligns with low-GWP refrigerant transition requirements now in effect for new residential HVAC equipment. This unit pairs with a compatible indoor air handler or furnace coil to form a complete split system.

Key Features

• 4,781 CFM heating airflow capacity
• Part of the Heil H5H8T deluxe heat pump series

Compatibility

Designed for use in residential ducted split-system configurations as part of the Heil H5H8T product group. Requires a compatible indoor coil or air handler rated for R454B refrigerant. Consult system matchup documentation to confirm rated SEER2 efficiency for specific indoor-outdoor combinations.

Installation Notes

Installation must be performed by a licensed HVAC technician holding appropriate EPA Section 608 certification for A2L refrigerants. Disconnect and lock out all electrical power before making any connections to the unit. R454B is an A2L mildly flammable refrigerant — follow current ASHRAE 15 and local mechanical code requirements for equipment room ventilation and refrigerant handling. Commission the system per manufacturer startup procedures and verify airflow, refrigerant charge, and electrical connections before returning the unit to service.
