Why Rheem Air Conditioner Split Systems Are the Ultimate Choice for Year-Round Comfort
The RA14AY outdoor unit and RB2TY indoor air handler work together as a compact central air system for 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 condenser is built for everyday cooling and easier service. 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. A swept-wing fan design 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 RB2TY is a short, low-profile air handler—only about 35 inches tall—so it can fit in tighter closets, attics, and crawl spaces. The sturdy steel cabinet can be installed in several positions—upflow, downflow, or on its side. One inch of insulation helps keep blower noise down, and the cabinet is well sealed (under 2% air leakage) so cooled air stays in the ducts instead of leaking into the attic or closet.
Together, the two units give you efficient cooling in a smaller footprint, with a compact indoor cabinet, safety features, and service access designed to keep the system running with fewer headaches.
