2 Ton Rheem 16 SEER2 R454B Two Stage Central System RA16AY24AJ2NA, RH2TY2417STANNJ
This Rheem Endeavor® Line Classic Plus® Series iM system brings two-stage comfort to smaller homes. The RA16AY24AJ2NA condenser runs most of the time on its low stage, then ramps to high stage on the hottest days. The RH2TY2417STANNJ air handler's two-stage airflow follows along. The match is AHRI certified at 16 SEER2 (#217168510). The result is longer, quieter cycles, steadier temperatures and better humidity control than a single-stage system. It uses low-GWP R-454B with Rheem's PlusOne® Refrigerant Detection System™. It's cooling only, with optional Rheem electric heat strips.
Is a 2 Ton Air Conditioning System the Right Size?
A 2 ton system delivers 24,000 BTU/h of nominal cooling at high stage. It's common in 2-bedroom homes, larger condos and starter homes around 900–1,200 sq. ft. as a general reference. On mild days, the low stage covers the load at reduced capacity.
Two-stage systems are more forgiving of sizing than single-stage, because low stage handles part-load hours. Proper sizing still matters: window area, insulation, duct leakage and occupancy all shape the load. A Manual J load calculation confirms 2 tons.
Ideal for: Humid-climate condos, starter homes and 2-bedroom houses where comfort and humidity control come first.

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
Do I need a two-stage thermostat for the RA16AY24AJ2NA?
To use both compressor stages, pair it with a thermostat that has two cooling stages (Y1 and Y2). The thermostat options offered with this system are all 2-cooling-stage models.
How is this two-stage system different from the single-stage 2 ton RA15AY24?
Both use the RH2TY2417STANNJ air handler and are rated 16 SEER2. The RA16AY24 adds a low stage for longer, quieter cycles and better dehumidification. Compare the single-stage 2 ton RA15AY24AJ1NA system.
Does the RA16AY24AJ2NA include pressure switches?
Yes. Rheem lists high and low pressure controls as factory standard on every RA16AY size. On many single-stage Rheem condensers, they're sold as accessories.
What crankcase heater fits the RA16AY24AJ2NA?
Rheem lists the 44-101884-08 crankcase heater with temperature thermostat, or the 44-17402-44 without one, as field-installed accessories for the RA16AY24.
Is there a 2 ton Rheem heat pump with the same air handler?
Yes. The 2 ton Rheem RP15AY24AJ2NA heat pump system pairs a heat pump with the RH2TY2417STANNJ for heating and cooling from the outdoor unit.
What is the Classic Plus series?
Classic Plus® is the Endeavor® Line series Rheem uses for the RA16AY. It adds a two-stage scroll compressor and factory pressure controls to Classic cabinet features like Triple Service Access and Expanded Valve Space.
