1.5 Ton Rheem 15.2 SEER2 R454B Central Wall Mount Apartment/Condo Type System RA14AY18AJ1NA, RF2TY2421STANSJ
This Rheem Endeavor® Line Classic® system pairs the RA14AY18AJ1NA condenser with the RF2TY2421STANSJ wall mount apartment/condo air handler, AHRI certified at 15.2 SEER2 (#215769991). The RF2TY uses a five-speed constant torque motor with two-stage airflow for quieter, more efficient operation in a compact 36" tall cabinet. It runs on low-GWP R-454B with Rheem's PlusOne® Refrigerant Detection System™. It's available with no heat or factory-installed 5, 8 or 10 kW breakered heat.
Is a 1.5 Ton Air Conditioning System the Right Size?
A 1.5 ton system delivers 18,000 BTU/h of nominal cooling. In apartments and condos, it typically serves units around 600–900 sq. ft. as a loose reference.
Top-floor units, west-facing glass and older windows add load, while interior units with neighbors on several sides need less. A Manual J load calculation confirms the right size for the unit.
Ideal for: Studios, 1-bedroom apartments and small condos with a wall mount air handler closet.
Need more capacity? Step up to the 2 Ton Rheem 15.2 SEER2 R454B Central Wall Mount Apartment/Condo Type System RA14AY24BJ1NA, RF2TY2421STANSJ, which uses the same 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
Why does a 1.5 ton system use the RF2TY2421 air handler?
The RF2TY2421 covers 1.5 and 2 ton matches. Rheem ships it on speed taps 4 and 5 for 2 tons, so the installer moves it to taps 2 and 3 for this 1.5 ton condenser.
What does the continuous fan setting do on the RF2TY?
Speed tap 1 is for continuous fan. Rheem sets it at 50% of the tap 4 airflow, so the fan can circulate and filter air quietly between cooling cycles.
Is there a short apartment-style alternative to this wall mount system?
Yes. If your closet suits a different cabinet, compare the 1.5 ton RA14AY18AJ1NA, RB2TY2417STANMJB short apartment/condo system.
Is there a heat pump version of this 1.5 ton wall mount system?
Yes. See the 1.5 ton Rheem RP14AY18AJ1NA, RF2TY2421STANSJ heat pump wall mount system, which uses the same air handler.
What factory heater options come with the RF2TY2421 in this system?
We offer it with no heat (N00) or factory-installed 5 kW (B05), 8 kW (B08) or 10 kW (B10) breakered heat. The "417" ending adds a factory float switch.
How much does the RF2TY2421STANSJ weigh?
Rheem lists a 95 lb unit weight and 105 lb shipping weight for the RF2TY2421.
