2 Ton Rheem 15.2 SEER2 R454B Central System RA14AY24BJ1NA, RH2TY2417STANNJ
The RA14AY24BJ1NA condenser and RH2TY2417STANNJ air handler combine into a 24,000 BTU matched split system rated at 15.2 SEER2 on R-454B refrigerant, certified under AHRI reference 216375597. Two tons is the workhorse size for starter homes, duplex units, and larger apartments, and this package delivers it without forcing a wider indoor cabinet: the air handler is the same 17.5-inch chassis used on the 1.5 ton system, so a step up in capacity does not mean rebuilding the closet.
Is a 2 Ton Refrigeration System the Right Size?
Two tons of cooling equals 24,000 BTU per hour. Across Florida and the Gulf Coast that commonly covers homes in the 900 to 1,200 square foot range. It is the size most often quoted for two-bedroom homes built in the 1960s through 1980s, townhouse end units, and second-floor zones in a two-system house.
Where 2 tons goes wrong is on homes that fall between sizes. A house that calculates at 1.8 tons will be better served here than by a 1.5 ton unit that runs continuously on design days, but a house calculating at 2.4 tons will feel under-served. Duct capacity matters too: the RH2TY2417STANNJ moves roughly 800 CFM at nominal, and undersized returns will limit that regardless of the equipment rating.
Ideal for: Two-bedroom homes, townhouses, duplex units, larger apartments, upstairs zones in dual-system homes, and small offices.
Need more capacity? Step up to the 2.5 Ton Rheem 15.2 SEER2 R454B System RA14AY30AJ1NA, RH2TY3617STANNJ, which adds 6,000 BTU while still using a 17.5-inch indoor cabinet.
Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, duct design, window area, ceiling height, occupancy, and local design conditions.

This pairing is worth noting for anyone upgrading from a 1.5 ton system: because the RH2TY2417STANNJ serves both the 18,000 and 24,000 BTU packages, the indoor cabinet dimensions, plenum transitions, and closet clearances stay the same. Only the outdoor unit and the line set sizing change. Heat kits, thermostats, and copper are sold separately.

Frequently Asked Questions
What does the B in RA14AY24BJ1NA mean compared to the A in other models?
The character in that position is Rheem's internal revision identifier for the outdoor unit. The 2 ton RA14AY carries a B where the surrounding tonnages carry an A. It does not change the nominal capacity, refrigerant, or the AHRI-rated 15.2 SEER2 performance of this matchup.
Is this the right system for a second-floor zone?
Two tons is a common choice for the upstairs half of a dual-system home, since second floors carry heavier roof and solar gain but less overall square footage. Confirm the upstairs duct system can carry the airflow before committing to the size.
How much airflow does the RH2TY2417STANNJ deliver at 2 tons?
Nominal airflow for a 2 ton application is in the neighborhood of 800 CFM. The constant torque ECM motor holds that target across a range of external static pressure; exact speed tap selections are listed in the RH2TY technical specifications linked above.
Do I need a special thermostat for the PlusOne Refrigerant Detection System?
No. Rheem designed the detection system to work with any 24V thermostat application, so standard programmable and non-programmable controls are compatible. Our programmable thermostats section covers the usual options.
What happens if the A2L sensor detects refrigerant?
The mitigation board pauses outdoor unit operation and runs the indoor blower to disperse refrigerant, which is the behavior required for A2L equipment. Normal operation resumes once the condition clears. Full sequence details are in the installation instructions.
Can I install this system myself?
R-454B is a mildly flammable A2L refrigerant and this equipment requires EPA Section 608 certification to charge and evacuate, plus local permitting and inspection in most jurisdictions. Budget Heating sells to homeowners and contractors alike, but the installation should be performed by a licensed HVAC contractor.
