Why Rheem Electric Air Handlers Are the Ultimate Choice for Year-Round Comfort
The RH2TY indoor air handler is built to move cooled or heated air through your home quietly and efficiently. It uses a newer, lower-impact refrigerant setup that already meets the EPA’s 2025 environmental rules, so you don’t have to worry about a major equipment change later.
Inside, the all-aluminum coil 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. One inch of insulation helps keep blower noise down.
A built-in refrigerant safety system watches for leaks. It works with a standard 24-volt thermostat and will automatically pause the outdoor unit if it detects too much refrigerant in the air.
Optional electric heat kits can be added for extra warmth on cooler days, and they include built-in breakers and a service disconnect for safety. Altogether, the RH2TY is a compact, service-friendly indoor unit designed to deliver dependable comfort in tight spaces.
