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.
