4 Ton Rheem 16 SEER2 R454B Variable Speed Inverter Heat Pump System RP17AY48AJVCA, RH2VY4821STACNJ
This 4-ton Rheem system matches the inverter-driven RP17AY48AJVCA condenser with the EcoNet-enabled RH2VY4821STACNJ variable-speed air handler for R-454B refrigerant. Communicating over EcoNet, the Constant CFM air handler and inverter compressor scale together to serve larger homes with strong capacity on design days and quiet, precise part-load comfort, earning an AHRI-certified 16 SEER2 / 11.0 EER2 rating with up to 9.5 HSPF2 heating.
Is the 4 Ton System the Right Size?
A 4-ton system typically fits larger homes of about 1,800 to 2,400 square feet, though open floor plans, high ceilings, and warm climates can raise the requirement considerably.
Large window areas, multiple stories, and higher occupancy increase heat gain that a load calculation captures far better than floor area. This communicating pairing suits homes where a single-stage unit would short-cycle, but confirm a nominal 4-ton system with a Manual J calculation.
Ideal for: larger single-family and two-story homes that want communicating variable-speed comfort with reliable capacity.
Need more capacity? Step up to the 5 Ton Rheem RP17AY60AJVCA Variable Speed System for the largest homes and light-commercial spaces.
Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, climate, ductwork, window load, and air-sealing. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Both units include an integrated PlusOne Refrigerant Detection System, and the air handler commissions dip-switch-free over Bluetooth.
Condenser & Air Handler Features
RP17AY48AJVCA Condenser
- Inverter-driven PlusOne variable-speed compressor prevents short-cycling on big loads
- Quiet as low as 58 dBA despite higher capacity
- 7mm copper coil and brushless DC condenser motor for efficiency
- EcoNet enabled with PlusOne Diagnostics & Bluetooth
- 10-year conditional parts warranty with registration
RH2VY4821STACNJ Air Handler
- EcoNet-enabled Constant CFM (variable-speed) ECM motor, two-stage airflow
- TXV metering and corrosion-resistant aluminum indoor coil
- 21-inch 4-way convertible cabinet for upflow, downflow, and horizontal
- Dip-switch-free Bluetooth commissioning via the Rheem Contractor App
- Accepts field-installed RXBH electric heat kits
Because both the condenser and the RH2VY air handler are EcoNet enabled, this is a fully communicating system. We recommend the Rheem EcoNet Smart Thermostat so the system auto-configures and gradually modulates capacity and airflow together for the best efficiency, humidity control, and quiet operation, plus remote monitoring and service alerts through the EcoNet app.

Frequently Asked Questions
Why is the 4-ton RH2VY system rated 16 SEER2?
16 SEER2 with 11.0 EER2 and up to 9.5 HSPF2 is the AHRI-certified rating for the RP17AY48AJVCA and RH2VY4821STACNJ matched combination.
What air handler is in the 4-ton RP17AY48 EcoNet system?
The RH2VY4821STACNJ, a 21-inch EcoNet-enabled Constant CFM variable-speed air handler with a TXV and aluminum coil.
Does this 4-ton system need the EcoNet thermostat to work?
The EcoNet Smart Thermostat is recommended to unlock full communicating, fully-modulating operation. The equipment can run on other controls, but communicating operation and app features require EcoNet.
How wide is the 4-ton RH2VY air handler cabinet?
The RH2VY4821STACNJ uses a 21-inch-wide cabinet and a 3/4 HP ECM motor to support 4-ton airflow.
Is this 4-ton system quieter than a single-stage system?
Yes. Variable-speed airflow, the inverter compressor, and 1-inch foil-faced cabinet insulation combine for notably quieter operation than fixed-capacity equipment.
Can I convert the 4-ton air handler to horizontal airflow?
Yes. It is 4-way convertible for upflow, downflow, and horizontal left or right; a horizontal adapter kit is available for upflow/downflow-only conversions where required.
