Icp H5H8T36AKAAA Heat Pump 18 SEER2 2-stage R454B

Product Description

The INTERNATIONAL COMFORT PRODUCTS H5H8T36AKAAA is a 2-stage, 18 SEER2 residential heat pump designed for whole-home heating and cooling applications. Operating on R454B refrigerant, this unit delivers efficient performance across two capacity stages, allowing the system to match output to actual load conditions rather than running at full capacity continuously. With a cooling airflow of 965 CFM, it is sized for mid-range residential installations. Licensed HVAC technicians handle the installation, startup, and commissioning of this equipment.

The H5H8T36AKAAA is intended for residential split-system heat pump installations where an air handler or furnace fan coil is paired with this outdoor condensing unit. The 2-stage operation supports improved comfort and dehumidification during cooling season by allowing extended low-stage runtimes. The unit uses R454B, a lower-global-warming-potential refrigerant that meets current regulatory requirements. It is marketed under the Heil brand and manufactured by ICP. Typical applications include new construction and replacement installations in single-family homes and light residential settings.

Key Features

• 18 SEER2 efficiency rating for compliance with current federal minimum efficiency standards
• 2-stage compressor operation for improved capacity control and comfort
• R454B refrigerant — lower GWP alternative meeting current refrigerant transition requirements
• 965 CFM cooling airflow suitable for mid-range residential tonnage applications

Compatibility

Designed as an OEM-matched outdoor heat pump unit within the Heil H5H8T product group. Compatible indoor equipment pairing should be confirmed using ICP or Heil ARI-certified matched system documentation prior to installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling refrigerants. Disconnect and lock out all electrical power at both the outdoor unit and the air handler before any service work. Follow local mechanical codes and manufacturer installation instructions for refrigerant line sizing, electrical disconnect requirements, and pad or mounting specifications. Do not attempt to charge, recover, or handle R454B refrigerant without proper equipment rated for A2L refrigerant service.
