Rheem Select 1.5 Ton Gas Split System – 80% AFUE – Upflow/Horizontal

The Rheem Select 1.5 Ton Gas Split System is a complete residential straight-cool configuration for properties that use a gas furnace for heating. It combines an R-454B outdoor air conditioner, a cased evaporator coil, and an 80% AFUE gas furnace designed for upflow or horizontal installation.

This system provides approximately 18,000 BTU of nominal cooling capacity. Actual performance depends on the complete equipment combination, installation conditions, ductwork, airflow, and the verified AHRI-rated match. A professional load calculation should be completed before selecting equipment.

Rheem Select 1.5 Ton Gas Split System Overview

The outdoor component is the Rheem Select WA14AY18AJ1NA air conditioner from the Endeavor Line Select Series. Rheem identifies this single-stage model as a nominal 1.5-ton unit using R-454B refrigerant and a 208/230-volt, single-phase electrical connection.

The outdoor unit is paired with the TCFY2414STAAMC cased evaporator coil and the W801T0503A14UHSNAS gas furnace. The furnace provides 50,000 BTU per hour of heating input and approximately 40,000 BTU per hour of heating output at 80% AFUE.

System Compatibility

The Rheem Select 1.5 Ton Gas Split System is intended for residential applications that require central air conditioning and gas heating. This Rheem Select 1.5 Ton Gas Split System uses matching 14-inch coil and furnace cabinets to support proper alignment during an upflow or horizontal installation.

The included evaporator coil has a higher nominal capacity designation than the outdoor unit. This can be appropriate in an approved matched system, but the exact combination must be confirmed through applicable manufacturer data and an AHRI certificate before a certified efficiency rating is represented.

Equipment size should never be selected only from square footage. Climate, insulation, windows, ceiling height, occupancy, duct condition, air leakage, and other building characteristics affect the required capacity. Use the Xpress AC Supply sizing calculator for preliminary guidance and obtain a professional Manual J load calculation before ordering.

Refrigerant Information

This Rheem Select 1.5 Ton Gas Split System uses R-454B refrigerant. R-454B is classified as an A2L refrigerant and requires compatible service equipment, components, installation procedures, and technician training.

Do not substitute equipment intended for a different refrigerant. The outdoor unit, indoor coil, metering device, line set, and applicable safety controls must meet the manufacturer’s R-454B installation requirements.

Warranty and Documentation

Warranty coverage for the Rheem Select 1.5 Ton Gas Split System depends on the individual component, installation, application, registration status, and current manufacturer terms. Review the documentation supplied with each component before installation. Registration may be required within the manufacturer’s stated period to receive conditional warranty coverage.

Visit the official Rheem WA14AY18AJ1NA product page for outdoor-unit information. Additional manuals and product documents can be located through the Rheem Resource Center.

For current warranty terms and registration guidance, consult the official Rheem warranty information. Warranty eligibility should be confirmed for every component in the package before purchase.

Professional Installation Notice

The Rheem Select 1.5 Ton Gas Split System must be installed and commissioned by qualified HVAC professionals familiar with gas-fired equipment and A2L refrigerants. Installation includes electrical work, refrigerant handling, venting, combustion-air verification, condensate drainage, gas-pressure adjustment, airflow setup, evacuation, charging, and safety testing.

Local permits, inspections, building codes, fuel-gas codes, and manufacturer instructions apply. Improper sizing or installation can reduce comfort and efficiency, damage equipment, create safety hazards, and affect warranty eligibility.
