The Rheem® Endeavor Line Prestige Series RD18AY is a high-efficiency inverter heat pump designed for flexible application in residential systems. It offers universal compatibility, working seamlessly with both Rheem® EcoNet® communicating systems and traditional non-communicating HVAC equipment. This unit utilizes R-454B, a low Global Warming Potential (GWP) refrigerant, to meet modern environmental standards while delivering reliable heating and cooling.Featuring a compact, side-discharge design, this heat pump is an ideal solution for installations with space constraints without sacrificing performance. The variable-speed technology provides precise temperature control for enhanced comfort, achieves high efficiency ratings up to 19.0 SEER2, and ensures quiet operation for minimal disruption.
- Variable-Speed Compressor: Features a PlusOne® variable speed twin rotary compressor with inverter drive for precise temperature and humidity control, operating from 45% to 100% capacity.
- Advanced Diagnostics: Equipped with PlusOne® Diagnostics and Bluetooth® connectivity, allowing for easy setup, monitoring, and troubleshooting via the Rheem® Contractor and EcoNet® apps.
- Quiet Operation: Engineered for minimal noise with sound-dampening features including a compressor sound cover, swept-wing fan technology, and an innovative drive system.
- Smart System Integration: EcoNet® enabled for automatic system configuration and performance optimization when installed with compatible Rheem® system components.
- Refrigerant Safety: Includes the PlusOne® Refrigerant Detection System™, an integrated sensor and mitigation board that pauses operation if excess A2L refrigerant is detected.
- Installation Flexibility: Utilizes traditional refrigerant piping, allowing for the use of existing line sets to simplify replacement installations.
