Aciq R5H5S18AKAAA 1.5 Ton 15.2 SEER2 Heat Pump Furnace System

Product Description

The ACIQ R5H5S18AKAAA / EAM5X19M17A / N80MSN0451412A is a dual-fuel combination system pairing a 1.5-ton single-stage heat pump condenser with an 80% AFUE gas furnace rated at 45,000 BTU/h. The system is rated at 15.2 SEER2 and uses R454B refrigerant, an A2L-classified refrigerant that requires pairing with an R454B-compatible air handler or evaporator coil equipped with a leakage detection system. The condenser ships factory pre-charged with refrigerant for a 15-foot line set. The furnace is multi-positional, supporting flexible installation orientations. Licensed HVAC technicians install and commission this system.

This combination system is suited for residential applications where a dual-fuel setup is preferred for efficiency across seasonal temperature ranges. The heat pump condenser handles cooling and moderate heating loads, while the gas furnace provides reliable backup heat during colder conditions. The condenser operates in heating mode between -10 degrees F and 66 degrees F outdoor ambient, and in cooling mode between 55 degrees F and 125 degrees F. The 80% AFUE furnace at 45,000 BTU/h is sized for smaller residential structures. This system is not a standalone unit and requires compatible indoor coil or air handler components to operate.

Key Features

• 1.5-ton single-stage scroll compressor condenser rated at 14.3 SEER2 and HSPF2 7.5-7.8
• Factory pre-charged with R454B refrigerant for a 15-foot line set, reducing field charging time
• Filter drier included for field installation
• 80% AFUE multi-positional gas furnace rated at 45,000 BTU/h for flexible installation
• Single-phase 208/230V electrical supply with a maximum breaker size of 15 amps

Compatibility

This system must be paired with an R454B-compatible indoor coil or air handler equipped with a refrigerant leakage detection system to comply with A2L refrigerant safety requirements. Consult ACIQ system matching guidelines to confirm compatible indoor unit configurations before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants. Shut off all electrical power and gas supply to the system before beginning any service or installation work. If the line set exceeds 15 feet, additional R454B refrigerant charge will need to be added per manufacturer specifications. Follow all applicable local codes, NEC requirements, and manufacturer installation instructions for refrigerant line sizing, electrical connections, and gas furnace venting.
