2 Ton Rheem 15.2 SEER2 R454B Two Stage Heat Pump System RP15AY24AJ2NA, RH2TY2417STANNJ
Built for homeowners ready to move to low-GWP refrigerant, this 2 ton Rheem system matches the RP15AY24AJ2NA two-stage heat pump with the RH2TY2417STANNJ air handler. It is rated 15.2 SEER2 and 11.7 EER2 under AHRI #215415449 and runs on R-454B, an A2L refrigerant Rheem developed this series around to meet the EPA's 2025 GWP limit. It is a strong replacement choice for townhomes, starter homes, and older 2 ton R-22 or R-410A systems.
Is a 2 Ton Heat Pump System the Right Size?
Rheem rates this match at 22,800 BTU/h of cooling and 22,600 BTU/h of heating at 47°F, a typical fit for smaller single-family homes, townhouses, and larger condos. Two-stage operation lets it run gently on low stage through most of the year.
Before replacing like-for-like, consider what has changed: new windows, attic insulation, or a sealed duct system can lower the load, while an enclosed porch or added room can raise it. Sun exposure and occupancy matter too. If the numbers land between sizes, our team can help you decide.
Ideal for: Townhomes, two- and three-bedroom starter homes, larger condos, and replacement of an aging 2 ton heat pump.
Need more capacity? Move up to the 2.5 Ton Rheem 15.2 SEER2 R454B Two Stage Heat Pump System RP15AY30AJ2NA, RH2TY3617STANNJ for homes with a heavier heating and cooling load.
Recommended system sizes are general guidelines only. Actual heating and cooling requirements depend on insulation, climate, windows, ductwork, ceiling height, and occupancy. A Manual J load calculation is the best way to confirm sizing. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Who is the 2 ton RP15AY24AJ2NA system best suited for?
It fits townhomes, starter homes, and larger condos with a load near 24,000 BTU/h. Confirm the size with a load calculation before you buy.
How does the 2 ton system compare with the 1.5 ton RP15AY18AJ2NA package?
Both use the RH2TY2417STANNJ air handler and the same 25" tall outdoor cabinet with an 83 oz charge. The 2 ton unit adds capacity and needs a 25 A maximum breaker versus 20 A for the 1.5 ton.
What is R-454B and why does this system use it?
R-454B is an A2L refrigerant with a global warming potential below the EPA's 2025 limit of 700. Rheem states it has a 78% lower GWP than R-410A while requiring only minimal changes to installation.
What is the PlusOne Refrigerant Detection System?
It is Rheem's one-box A2L sensor and mitigation board. If excess refrigerant is detected, it automatically pauses outdoor unit operation, and it works with any 24V thermostat.
Can the RH2TY2417STANNJ be installed in a downflow position?
Yes. The RH2TY is 4-way convertible for upflow, downflow, horizontal left, or horizontal right. Rheem offers combustible floor base accessories for downflow installs.
What is the EER2 rating of this 2 ton system?
Rheem's tested combination data lists 11.7 EER2 along with 15.2 SEER2 and 7.8 HSPF2 for this match.
