2 Ton Rheem 15.2 SEER2 R-454B Short Apartment/Condo Air Conditioning System
By matching the RA14AY24BJ1NA condenser with the larger 21" RB2TY3621STANMJB low-boy air handler, this 2 ton (24,000 BTU) Rheem package climbs to an AHRI-certified 15.2 SEER2 (AHRI #217450786), the top efficiency rating listed for the RA14AY series. The bigger coil and 1/2 HP constant-torque ECM blower give one- and two-bedroom condos lower operating costs and more airflow headroom, while the 35" cabinet height still clears short closets and soffits. It is the smart upgrade for owners and contractors who have a little extra closet width and want the most efficient 2 ton short apartment system Rheem offers here, with 5, 7, or 10 kW electric heat.
Is a 2 Ton High-Efficiency Short System the Right Size?
A 2 ton system typically matches homes of roughly 900 to 1,200 square feet. Choosing the higher-efficiency air handler does not change the capacity a home needs, only how efficiently it is delivered, so the sizing still comes down to the calculated cooling load.
Ductwork deserves a look on any replacement. The RB2TY3621STANMJB has a larger 19-3/8" x 19-3/4" return opening and supply outlet than the 17-1/2" model, so existing transitions may need adjusting. In return, the extra airflow capacity helps the system hold comfort on hot afternoons and supports a 10 kW heat strip for colder regions.
Ideal for: Two-bedroom condos, owner-occupied units focused on lower electric bills, renovations where the closet can accept a 21" cabinet, and 2 ton apartment change-outs that need more electric heat capacity.
Need more capacity? Step up to the 2.5 Ton Rheem 15.2 SEER2 RA14AY30AJ1NA & RB2TY3621STANMJB Short Apartment System for larger condos requiring additional cooling capacity.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, windows, sun exposure, ceiling height, climate, occupancy, and ductwork. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Why is this 2 ton system rated higher than the 2 ton with the 17-1/2" air handler?
The RB2TY3621STANMJB has a larger coil and a 1/2 HP ECM blower, which lifts the AHRI-certified rating to 15.2 SEER2 versus 14.3 SEER2 for the 2 ton system with the RB2TY2417STANMJB. The trade-off is a cabinet that is 3-1/2" wider.
Will the 21" RB2TY3621STANMJB fit my existing apartment closet?
Measure first. The cabinet is 21" wide and 35" tall with a 19-3/8" x 19-3/4" return opening. If the closet only fits a narrower unit, the 17-1/2" model is the better match.
Can I get 10 kW of electric heat with this 2 ton system?
Yes. Because it uses the 21" cabinet, this system offers 5, 7, or 10 kW heat strips. The 10 kW model lists a 44.1 amp minimum circuit ampacity at 240V, so confirm the electrical service can support it.
What clearances does the RA14AY24BJ1NA need outdoors?
The RA14AY clearance diagram shows 24" of service clearance and lists 24" recommended (6" minimum) on other sides, with exact distances depending on wall layout; see the RA14AY technical specifications. In alcoves or roof wells, ensure enough ventilation to prevent hot discharge air from recirculating.
Is there a wall-hung Rheem alternative at the same efficiency?
Yes. The 2 ton Rheem RF2TY wall mount apartment system pairs the same condenser with a wall-hung fan coil, also at 15.2 SEER2, for closets designed around wall-mounted units.
Who should choose the high-efficiency 2 ton short system?
Condo owners who pay their own electric bill, investors upgrading units for long-term rental, and contractors who want extra airflow and heat strip capacity in a short closet are the best fit.
