Description
This Rheem 4 ton dual fuel split system pairs the RP17AY48AJVCA heat pump, the RCFY4824STANMC cased evaporator coil and the R801V1255A24UHSCAP 80% AFUE gas furnace. It is an AHRI-certified match (AHRI reference 218160477), rated at 45,000 BTU/h of cooling and 16 SEER2 with 9.5 HSPF2 heating efficiency. All three pieces use R-454B refrigerant.
How the pieces work together
The outdoor heat pump uses a variable-speed compressor that adjusts its output in small steps for very even temperatures and humidity control. In mild weather the heat pump heats the home with electricity, and when it gets cold enough the system switches over to the gas furnace, so you use whichever fuel is cheaper and more comfortable at the moment. Inside, the 24.5" wide RCFY coil sits flush on the 24.5" furnace cabinet, so the installer gets a clean, square stack with no transition to fabricate.
The furnace delivers 125,000 BTU/h of input with single stage heat and a variable-speed ECM blower sized for up to 5 tons of airflow. As an 80% furnace it vents into a standard B-vent or lined chimney. The cabinet installs upflow or horizontal.

Frequently Asked Questions
What is included?
One RP17AY48AJVCA outdoor heat pump, one RCFY4824STANMC cased coil and one R801V1255A24UHSCAP gas furnace. The refrigerant line set, thermostat, venting, drain parts and pad are sold separately.
Is this system AHRI certified?
Yes. This exact combination is listed in the AHRI directory under reference number 218160477, which many utility rebates and permit offices ask for.
What size home is a 4 ton system good for?
It depends on your climate, insulation, windows and ductwork. A Manual J load calculation from your installer is the best way to confirm 4 tons of cooling and 125,000 BTU of heat are right for your home.
Does a dual fuel system need special controls?
Yes. The system needs a thermostat or control that can switch between the heat pump and the furnace based on outdoor temperature. Your installer will set the switchover point for your area and fuel prices.
Does it need professional installation?
Yes. Gas, electrical and refrigerant work must be done by a licensed professional, and Rheem requires product registration for full warranty coverage.
