5 Ton Rheem 15.2 SEER2 R-454B Two-Stage Heat Pump Split System

Why Rheem Heat Pump Split Systems Are the Ultimate Choice for Year-Round Comfort

The Rheem RP15AY outdoor unit and RH2TY indoor air handler work together as a compact heat pump system that both cools and heats your home. They use a newer, lower-impact refrigerant that already meets the EPA’s 2025 environmental rules, so you don’t have to worry about a major equipment change later.

Outside, the two-stage compressor can run at a lower speed most of the time for more even temperatures, better humidity control, and quieter everyday operation. An inverted reversing valve helps the system switch between heating and cooling more smoothly and puts less stress on the piping. Extra room around the valves and a wide 15-inch service opening make it easier for a technician to work on the unit without tearing the cabinet apart. The insulated cabinet also helps keep outdoor noise down.

A built-in refrigerant safety system watches for leaks. It works with a standard 24-volt thermostat and will automatically shut the outdoor unit off if it detects too much refrigerant in the air.

Inside, the air handler uses an all-aluminum coil that holds up better against corrosion. The sturdy steel cabinet can be installed in several positions—upflow, downflow, or on its side—so it can fit in tighter spaces. It is also well sealed (under 2% air leakage) so conditioned air stays in the ducts instead of leaking into the attic or closet. Optional electric heat kits can be added for extra warmth on the coldest days, and they include built-in breakers and a service disconnect for safety.

Together, the two units give you efficient heating and cooling in a smaller footprint, with safety features and service access designed to keep the system running with fewer headaches.
