Description
Rheem 4 Ton Air Conditioner Split System: RA19AY48AJVCA + RHMVY4821SEACAJ
This system pairs the Rheem RA19AY48AJVCA air conditioner from the Endeavor Line Prestige Series with the RHMVY4821SEACAJ air handler. It is an AHRI-matched combination (AHRI reference 215737298), which means the efficiency numbers below were certified for these two exact models working together. It provides central cooling, and the air handler can take an electric heat strip if you want electric heat from the same system.

Electric heat
No heat strip is included with this system. If you want auxiliary or emergency electric heat, choose one from the Add an Electric Heat Strip option above. These are the Rheem kits approved for this air handler: RXBH-1724A05J-B (4.8 kW), RXBH-1724A07J-B (7.2 kW), RXBH-1724A10J-B (9.6 kW), RXBH-1724A15J-B (14.4 kW), RXBH-1724A18J-B (17.0 kW), RXBH-24A20J-B (19.2 kW), RXBH-24A25J-B (24.0 kW).
Sizing and installation
Size the system from a room-by-room load calculation (ACCA Manual J) rather than square footage alone. Climate, insulation, windows and duct condition all change the load, and an oversized system short-cycles and leaves humidity behind.
The outdoor unit and air handler each need their own electrical circuit sized to the rating plate. The refrigerant line set, thermostat (this system requires the RETST800SYS control), condensate drain, pad and installation materials are sold separately. Because R-454B is a mildly flammable (A2L) refrigerant, installation and service require a licensed HVAC technician using A2L-rated tools and the manufacturer's procedures, which also keeps the warranty in force.
Common questions
Is this a matched system?
Yes. AHRI certificate 215737298 covers the RA19AY48AJVCA with the RHMVY4821SEACAJ.
Does it come with a heat strip?
No. Heat strips are sold separately and can be added from the option above.
Can I reuse my old refrigerant lines?
Sometimes. Line sizes must match the outdoor unit and the lines must be clean, leak-free and compatible with R-454B. Your installer should inspect them and flush or replace them as needed.
