2.5 Ton Rheem 15.2 SEER2 R454B Central System RA14AY30AJ1NA, RH2TY3617STANNJ
At 30,000 BTU and 15.2 SEER2, this Rheem Endeavor Line package sits in the middle of the residential range and solves a problem homeowners hit constantly: needing more than 2 tons without the wider indoor cabinet that usually comes with it. The RA14AY30AJ1NA condenser is matched to the RH2TY3617STANNJ air handler — a 36-size coil in a 17.5-inch chassis — under AHRI reference 215232493. For a retrofit where the closet is fixed and the load calculation came back at 2.5 tons, this is the combination that fits.
Is a 2.5 Ton Refrigeration System the Right Size?
Thirty thousand BTU per hour typically serves 1,200 to 1,500 square feet in a hot, humid climate. This is the size that frequently shows up on three-bedroom ranch homes, older Florida block construction with moderate insulation, and 1,300 square foot homes that have added attic insulation or impact windows since the original system was installed.
The half-ton steps matter more than people expect. A home that has been re-roofed with radiant barrier or had its ductwork sealed can legitimately drop from 3 tons to 2.5 without losing comfort, and the smaller system will hold humidity better because it runs longer cycles. Conversely, adding conditioned square footage or replacing shade trees often pushes a 2.5 ton home into 3 ton territory. Confirm with a load calculation rather than matching the old nameplate.
Ideal for: Three-bedroom ranch homes, mid-size single-story houses, well-insulated 1,400 square foot homes, and retrofits where the existing closet cannot be widened.
Need more capacity? Step up to the 3 Ton Rheem 15.2 SEER2 R454B System RA14AY36AJ1NA, RH2TY3617STANNJ, which uses this exact air handler with a larger outdoor unit.
Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, duct design, window area, ceiling height, occupancy, and local design conditions.

The RH2TY3617STANNJ is the largest coil Rheem builds into the narrow 17.5-inch cabinet, and it steps the blower up to a 1/2 HP constant torque ECM motor. That extra motor capacity is what allows a 2.5 or 3 ton load to be served without moving to a 21-inch chassis. Electric heat kits, line sets, and controls are ordered separately.

Frequently Asked Questions
Why does a 2.5 ton system use a 36-size air handler?
Rheem builds the RH2TY3617STANNJ to cover both 2.5 and 3 ton applications. The 36 in the model refers to the coil family, not a fixed 3 ton output. Paired with the RA14AY30AJ1NA, the certified capacity for this combination is 2.5 tons under AHRI 215232493.
My old system was 3 tons. Can I drop to 2.5?
Often yes, particularly if the home has gained attic insulation, impact or low-E windows, a radiant barrier, or sealed ductwork since the original install. Downsizing correctly improves humidity control. Downsizing on a guess does not, so run a load calculation first.
What blower motor is in the RH2TY3617STANNJ?
It uses a 1/2 HP constant torque ECM motor, a step up from the 1/3 HP motor in the 17-size cabinet. That additional capacity is what lets the narrow 17.5-inch chassis carry 2.5 and 3 ton airflow.
Will this system dehumidify better than my old single-stage unit?
Two-stage airflow generally produces longer run times at lower speed, and longer run times remove more moisture per hour of operation than short high-speed cycles. Actual results depend on correct sizing, duct sealing, and thermostat setup.
Does the 10-year parts warranty apply automatically?
Rheem's 10-year conditional parts coverage requires product registration within the period stated on the warranty certificate linked above. Without registration, a shorter standard term applies. Register the serial numbers as soon as the system is commissioned.
