Rheem Select 1.5 Ton Heat Pump System – Multiposition – 14.3 SEER2

The Rheem Select 1.5 Ton Heat Pump System is a complete electric heating and cooling package designed for residential applications. It combines the Rheem Select WP14AY18AJ1NA outdoor heat pump, WH2TY2417STANNJ multiposition air handler, and RXBH-1724A10J-B electric auxiliary heat kit.

The WP14AY18AJ1NA provides approximately 18,000 BTU per hour of nominal capacity and uses R-454B refrigerant. When matched with the WH2TY2417STANNJ air handler, the certified combination delivers 17,100 BTU per hour of total cooling capacity, 14.3 SEER2, 9.0 EER2, and 7.5 HSPF2 under AHRI reference number 217047498.

The heat pump supplies both cooling and primary electric heating by transferring heat between the indoor and outdoor environments. The RXBH-1724A10J-B electric heat kit provides supplemental or auxiliary heat when required by outdoor conditions, thermostat demand, or system configuration.

Correct system capacity must be determined through a professional HVAC load calculation. Square footage alone does not account for climate, insulation, windows, construction, occupancy, ductwork, air leakage, building orientation, and other conditions that affect heating and cooling requirements.

Rheem Select 1.5 Ton Heat Pump System Overview

The Rheem Select 1.5 Ton Heat Pump System uses the WP14AY18AJ1NA from the Rheem Endeavor® Line Select™ WP14AY series. Unlike a straight-cool air conditioner, this outdoor unit contains a reversing valve that allows it to provide both cooling and heat-pump heating.

The 1.5-ton WP14AY18AJ1NA uses a single-stage scroll compressor and operates on 208/230-volt, single-phase electrical service. The outdoor cabinet includes louvered panels that help protect internal components and an expanded service-valve area designed to improve technician access.

The WH2TY2417STANNJ is a two-ton nominal air handler used as the compatible indoor component in this 1.5-ton certified system. Using an indoor unit with a nominal capacity greater than the outdoor unit is acceptable only when the complete combination is manufacturer-approved and AHRI certified, as it is in this application.

System Compatibility

The ratings stated for the Rheem Select 1.5 Ton Heat Pump System apply specifically to the WP14AY18AJ1NA and WH2TY2417STANNJ combination represented by AHRI reference number 217047498. The selected RXBH-1724A10J-B heat kit provides auxiliary electric heating but does not change the identity of the certified outdoor and indoor heat-pump combination.

Substituting an outdoor heat pump, air handler, indoor coil, metering device, heat kit, or airflow setting can change capacity, efficiency, electrical requirements, and AHRI certification. All selected components must be verified before shipment and installation.

R-454B Refrigerant Information

The Rheem Select 1.5 Ton Heat Pump System uses R-454B refrigerant. R-454B is classified as an A2L refrigerant and requires compatible equipment, tools, components, installation procedures, and safety practices.

The WH2TY air handler incorporates refrigerant detection and mitigation components for the R-454B application. The installer must follow Rheem requirements for refrigerant piping, required detection components, airflow, equipment placement, leak testing, evacuation, charging, commissioning, and service access.

Warranty and Official Documentation

Warranty coverage depends on the individual component, residential or commercial application, installation, registration status, location, and Rheem’s complete warranty terms. Rheem lists five-year limited parts coverage for applicable unregistered equipment and conditional ten-year coverage for qualifying registered products. Registration requirements and exceptions must be reviewed before representing the final coverage.

Review the official Rheem warranty and registration portal and retain the equipment model numbers, serial numbers, installation date, and installing contractor information.

Additional technical details are available on the official Rheem WP14AY18AJ1NA product page, the Rheem WH2TY2417STANNJ product page, and the Rheem WP14AY technical specifications.

Professional Installation Notice

The Rheem Select 1.5 Ton Heat Pump System requires professional installation. A qualified HVAC contractor must verify the building load, equipment match, electrical service, breaker and conductor sizes, refrigerant piping, condensate drainage, ductwork, airflow, equipment clearances, permits, and local code requirements.

Use the Xpress AC sizing calculator only as an initial planning resource. Final capacity and equipment selection should be confirmed through an appropriate residential load calculation before purchasing or installing the system.
