Rheem has introduced the Endeavor Line Classic Plus Series Top-Discharge Universal Heat Pump, model RP17AY. This is an ENERGY STAR-certified residential HVAC unit designed to provide both cooling and heating through a split-system cabinet configuration.
The Endeavor Line Classic Plus Series Top-Discharge Universal Heat Pump achieves cooling efficiencies of up to 17 SEER2 and heating efficiencies of 9.5 HSPF2. The model operates with R-454B refrigerant to meet modern environmental standards while delivering year-round temperature control. The unit incorporates variable-speed performance via a twin rotary compressor and inverter drive, allowing it to run between 35% and 100% capacity for more precise temperature and humidity management.
Homeowners seeking to replace aging equipment will appreciate the universal compatibility, as the unit pairs with nearly any existing R-454B system and requires minimal modifications for installation.
