5 Ton Rheem 13.8 SEER2 R454B Single Stage Central System RA14AY60AJ1NA, RH1AY6021STANAJ
This Rheem Endeavor® Line Classic® system pairs the RA14AY60AJ1NA condenser with the RH1AY6021STANAJ single-stage-airflow air handler, AHRI certified at 13.8 SEER2 (#217232260). The air handler fits a 5 ton A-coil into a 21" wide cabinet, which helps where the closet or platform can't take a 24.5" unit. The condenser includes a factory-installed crankcase heater. It uses low-GWP R-454B with Rheem's PlusOne® Refrigerant Detection System™. It's cooling only, with Rheem electric heat strips up to 20 kW offered.
Is a 5 Ton Air Conditioning System the Right Size?
A 5 ton system delivers 60,000 BTU/h of nominal cooling, the top of the residential split-system range. It's often used in homes around 2,500–3,000+ sq. ft. as a loose guide, and in some light commercial spaces.
Before choosing 5 tons, confirm the load. Many larger homes are better served by two smaller zoned systems. A Manual J load calculation and a duct review make sure one 5 ton system is the right call.
Ideal for: Large homes and light commercial spaces where the air handler space is limited to about 21".
Need the wider air handler? Compare the 5 Ton Rheem 13.8 SEER2 R454B Single Stage Central System RA14AY60AJ1NA, RH1AY6024STANNJ with the 24.5" air handler.
Recommended home sizes are general guidelines only. Actual system requirements depend on insulation, climate, windows, ductwork, occupancy and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What coil type does the RH1AY6021STANAJ use?
The "A" coil series code means it uses an A-coil. It fits into a 21" wide cabinet that's 57" tall, making it the tallest RH1AY.
Should I choose the RH1AY6021STANAJ or RH1AY6024STANNJ?
Choose the RH1AY6021STANAJ when your space is built for a 21" air handler. If you have room for a 24.5" cabinet, see the RA14AY60AJ1NA, RH1AY6024STANNJ system.
Is the RA14AY60 crankcase heater installed at the factory?
Yes. Rheem states that RA14AY60 models come with a 44-103663-16 crankcase heater factory installed, so no add-on is needed.
Is there a two-stage airflow version with the 21" air handler?
Yes. The 5 ton RA14AY60AJ1NA, RH2TY6021STANAJ system uses the same condenser with a 21" two-stage-airflow RH2TY air handler.
What is the no-heat circuit rating for the RH1AY6021STANAJ?
Rheem lists 5.6 motor amps, a 7.0 amp minimum circuit ampacity and 15 amp maximum overcurrent protection at 208/240V without electric heat.
Can the RH1AY6021STANAJ sit on a wood floor in a downflow install?
Yes, with Rheem's RXHB-21 combustible floor base, which is required for downflow installs on combustible floors.
