TL;DR
Rheem has announced the release of the RP17AY, a variable-speed air-source heat pump compatible with most existing HVAC systems. It features high seasonal efficiency, supports multiple installation scenarios, and integrates with Rheem’s EcoNet ecosystem.
Rheem has introduced the RP17AY, a new variable-speed air-source heat pump engineered for high efficiency and universal compatibility in residential applications. The system uses R-454B refrigerant and is designed to simplify retrofit projects, offering flexible installation options and integration with Rheem’s connected EcoNet ecosystem.
The RP17AY system measures 991 mm x 908 mm x 908 mm and weighs 125 kg. It offers nominal cooling capacities from 2 to 5 tons, with a maximum of 60,000 BTU/h, and operates on a 208/230 V, single-phase, 60 Hz power supply. Its inverter-driven twin rotary compressor modulates from roughly 35% to 100%, supported by a brushless DC condenser fan motor, enabling high seasonal efficiency with a SEER2 of up to 17 and an HSPF2 of up to 9.5, according to Rheem.
The unit is compatible with both communicating and legacy 24V non-communicating controls, allowing it to integrate seamlessly with existing indoor coils and air handlers. Its design supports multiple installation scenarios through standardized control logic and flexible pairing, making it suitable for retrofit-heavy markets. Additionally, it incorporates safety features for handling R-454B’s mildly flammable A2L refrigerant, including refrigerant detection and automatic shutdown systems.
Rheem also announced that the RP17AY integrates with their EcoNet connected ecosystem, offering Bluetooth-enabled commissioning, onboard diagnostics, and remote monitoring, aimed at streamlining installation and ongoing maintenance.
Impact on Residential HVAC Retrofit Market
The release of the RP17AY could significantly influence the residential HVAC retrofit market by simplifying system upgrades and reducing installation complexity. Its universal compatibility means contractors can replace existing units without extensive modifications, potentially accelerating adoption of energy-efficient heat pumps. The integration with Rheem’s EcoNet ecosystem also offers long-term benefits in system monitoring and optimization, aligning with growing consumer interest in smart home technologies.
