2.5 Ton Rheem 15.2 SEER2 R454B Central System RA15AY30AJ1NA, RH2TY3617STANNJ
This Rheem Endeavor® Line Classic® system combines the RA15AY30AJ1NA condenser with the RH2TY3617STANNJ two-stage-airflow air handler, AHRI certified at 15.2 SEER2 (#215270465). It delivers 30,000 BTU/h on low-GWP R-454B refrigerant, with Rheem's PlusOne® Refrigerant Detection System™ in the air handler to pause the outdoor unit if a leak is found. From 2.5 tons up, the RA15AY adds Rheem's Swept Wing fan blade for quieter airflow. It's cooling only, with optional Rheem electric heat strips.
Is a 2.5 Ton Air Conditioning System the Right Size?
A 2.5 ton system delivers 30,000 BTU/h of nominal cooling. It's commonly used in 2- to 3-bedroom homes, often around 1,200–1,500 sq. ft. as a rough reference. That range shifts a lot with climate and construction.
West-facing glass, vaulted ceilings, older windows and leaky attic ducts can push a home toward 3 tons, while a tight, well-insulated home may need less. A Manual J load calculation gives a reliable answer before you buy.
Ideal for: 2- to 3-bedroom single-family homes, townhomes and mid-size ranch homes.
Need more capacity? Step up to the 3 Ton Rheem 15.2 SEER2 R454B Central System RA15AY36AJ1NA, RH2TY3617STANNJ, 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 is the 2.5 ton RA15AY30 taller than the 2 ton?
Rheem lists the RA15AY30AJ1NA at 27" tall, compared with 25" for the RA15AY24. Both share the 33.75" x 33.75" footprint, so the extra height adds coil surface without a larger pad.
What is Rheem's Swept Wing fan?
It's a fan blade design Rheem uses to move air through the condenser more quietly. Paired with an optimized venturi, it helps lower sound levels. On the RA15AY line it's used from 2.5 tons up.
How does this compare to the Rheem Select 2.5 ton system?
Both are rated 15.2 SEER2 and use the RH2TY3617STANNJ air handler. The Classic RA15AY30 adds a 2-row coil, Swept Wing fan and PlusOne service features. See the Rheem Select WA14AY30AJ1NA system to compare.
How do technicians get into the RA15AY30AJ1NA control box?
Rheem designed the control box to open by removing just two screws, with quick-release louver panels and no fasteners along the bottom of the cabinet. That shortens service time.
What accessories are available for the RA15AY30AJ1NA?
Rheem lists a low ambient kit (RXAD-A08), sound cover (68-23427-26), hard start kit (SK-A1), time delay (RXMD-B01), high and low pressure switches, and a liquid line solenoid (200RD2T3TVLC).
What airflow does the RH2TY3617STANNJ deliver at 2.5 tons?
Rheem's airflow limits for a 2.5 ton RH2TY list 900 CFM minimum, 1,000 CFM nominal and 1,125 CFM maximum. The installer sets the correct speed tap during startup.
