5 Ton Rheem 13.8 SEER2 R454B Central System RA14AY60AJ1NA, RH2TY6024STANNJ
This is the top of the RA14AY range: 60,000 BTU of cooling at 13.8 SEER2, built on low-GWP R-454B refrigerant and certified under AHRI reference 216011746's sibling listing 215232991. The RA14AY60AJ1NA condenser is matched here to the full-width RH2TY6024STANNJ air handler, a 24.5-inch cabinet that gives the coil and blower the face area to move 5 tons of airflow without straining. When the load calculation says 5 tons and the mechanical room has the room, this is the configuration to specify.
Is a 5 Ton Refrigeration System the Right Size?
Five tons delivers 60,000 BTU per hour and typically serves 2,400 to 3,000 square feet in a hot, humid climate. It is the largest single-phase residential split system commonly installed, and it shows up on large open-plan homes, two-story houses with a single central system, and light commercial spaces such as restaurants, salons, and small warehouses with conditioned office areas.
Five tons is also the size where a single system starts to become the wrong architecture. A 3,000 square foot two-story home served by one 5 ton system will almost always have a comfort imbalance between floors that no amount of capacity fixes. If you are replacing a 5 ton unit that never kept the second floor comfortable, the answer is usually zoning or a second system, not more tonnage.
Ideal for: Large open-plan homes, 2,400 to 3,000 square foot houses, restaurants and retail spaces, salons, and conditioned office areas within light industrial buildings.
Tight on closet width? The 5 Ton Rheem 13.8 SEER2 R454B System RA14AY60AJ1NA, RH2TY6021STANAJ delivers the same capacity in a 21-inch air handler cabinet.
Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, duct design, window area, ceiling height, occupancy, and local design conditions.

The 24.5-inch RH2TY6024STANNJ is the widest cabinet in the RH2TY family and the preferred choice for new construction or any installation where mechanical room space is not the constraint. The larger coil face area keeps face velocity and pressure drop down at 5 ton airflow, which is exactly what you want on a system that will run long cycles through a Gulf Coast summer.

Frequently Asked Questions
What is the difference between the RH2TY6024STANNJ and the RH2TY6021STANAJ?
Cabinet width. The 6024 uses a 24.5-inch chassis and the 6021 uses a 21-inch chassis. Both serve 5 ton applications with the same RA14AY60AJ1NA condenser; the wider cabinet offers more coil face area, while the narrower one fits closets that cannot accommodate 24.5 inches.
Why is 5 ton rated lower than smaller sizes at 13.8 SEER2?
Each matched pair is tested and certified independently. At 5 tons the airflow and refrigerant mass flow through the coil geometry produce a 13.8 SEER2 result, compared with 14.8 at 4 tons and 15.2 through 3.5 tons. All three exceed the federal minimum for the Southeast region.
Should a 3,000 square foot two-story home use one 5 ton system?
Often not. A single system serving two floors usually leaves the upper floor warm regardless of capacity, because the load and the stack effect differ by floor. Zoning or two separate systems generally produces better comfort than adding tonnage.
Is a 5 ton system available in three-phase?
This package is 208-230V single phase. For three-phase requirements, our complete split systems category and commercial equipment sections list the models configured for 3-phase service.
How much airflow does the RH2TY6024STANNJ move?
Nominal airflow for a 5 ton application is in the range of 1,800 CFM. Speed tap selections and external static pressure curves are published in the RH2TY technical specifications linked above; the blower performs best between roughly 0.3 and 0.7 inches W.C.
What filter size does a 5 ton system require?
Filter area should be sized to the airflow rather than the cabinet. At roughly 1,800 CFM, a single undersized return filter will create high pressure drop and noise. Plan on a large-area media filter or multiple returns, and size the grille from the airflow figures in the submittal sheet.
