5 Ton Rheem 13.8 SEER2 R454B Central System RA14AY60AJ1NA, RH2TY6021STANAJ
Five tons of cooling in a 21-inch air handler cabinet. This Rheem Endeavor Line package pairs the RA14AY60AJ1NA condenser with the RH2TY6021STANAJ, the narrow-chassis version of Rheem's 5 ton air handler, for 60,000 BTU at 13.8 SEER2 on low-GWP R-454B refrigerant under AHRI reference 216011746. It exists for one specific and very common problem: the load calls for 5 tons, but the closet, attic platform, or mechanical chase will not take a 24.5-inch cabinet.
Is a 5 Ton Refrigeration System the Right Size?
Sixty thousand BTU per hour generally covers 2,400 to 3,000 square feet in a hot, humid climate. What makes this particular 5 ton package different is not the capacity but the packaging: the RH2TY6021STANAJ carries 4.5 to 5 ton airflow in a 21.5-inch cabinet, three and a half inches narrower than the standard 5 ton chassis.
That difference decides jobs. Condominium mechanical closets, interior chases in 1970s and 1980s construction, and attic platforms framed between trusses frequently cap out at 21 or 22 inches of usable width. On those installations the choice used to be structural modification or a downsized system that never quite kept up. This model removes that tradeoff, at the cost of slightly less coil face area than the wide-cabinet version.
Ideal for: Retrofits with fixed closet width, condominium and townhouse mechanical chases, attic platforms framed between trusses, and any 5 ton replacement where widening the opening is not practical.
Have the space for a wider cabinet? The 5 Ton Rheem 13.8 SEER2 R454B System RA14AY60AJ1NA, RH2TY6024STANNJ uses the full 24.5-inch air handler for maximum coil face area.
Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, duct design, window area, ceiling height, occupancy, and local design conditions.

Frequently Asked Questions
Do I give up capacity by choosing the 21-inch cabinet?
No. The RH2TY6021STANAJ is rated for 4.5 to 5 ton applications and this pairing carries a full 60,000 BTU nominal capacity at 13.8 SEER2 under AHRI 216011746, the same rated efficiency as the wide-cabinet version.
What is the actual cabinet width I should plan for?
Rheem lists this chassis in the 21-inch class, with the published dimension at 21.5 inches. Add service and door clearance on top of that when measuring a closet opening, and confirm against the RH2TY submittal sheet before committing to the framing.
Why would a builder choose this over the 24.5-inch model?
Floor plan efficiency. In multi-family and townhouse construction, reclaiming three and a half inches of chase width across dozens of units adds up, and the narrower cabinet lets a 5 ton system fit chases originally detailed for 4 ton equipment.
Is the outdoor unit different from the wide-cabinet 5 ton system?
No. Both packages use the RA14AY60AJ1NA condenser. Pad size, line set sizing, and electrical requirements are identical; the difference is entirely on the indoor side and in the AHRI certificate number.
Can this air handler go in an attic between trusses?
The narrower footprint makes attic placement easier where truss spacing limits width, and the unit supports horizontal left and horizontal right orientations. Attic installs still require a secondary drain pan, a float switch, and code-compliant platform and walkway access.
What should I check on a condo retrofit before ordering?
Measure the closet opening and door width, confirm the supply plenum transition can be adapted, verify condensate routing and the available electrical service, and check any HOA rules on outdoor unit placement and sound. Our team can review the details at 813-885-7999.
