4 Ton Rheem 16 SEER2 R-454B 80% AFUE 75,000 BTU Two-Stage Variable Speed Upflow/Horizontal Gas Furnace Split System

This is a matched Rheem Endeavor Line residential system designed for efficient cooling and heating. It uses low-GWP R-454B refrigerant and pairs a 16 SEER2 two-stage air conditioner with a multi-position cased evaporator coil and an 80% AFUE single-stage gas furnace with variable-speed blower.  Together they form a complete heating-and-cooling system suitable for many residential applications, offering solid efficiency, quieter operation, and service-friendly design features.

Outdoor Condenser (RA16AY48AJ2NA)

• Two-stage scroll compressor (high and low speeds) for better temperature control, improved humidity removal, and higher efficiency vs. single-stage
• Swept-wing fan technology for quieter operation and improved acoustics
• 7 mm condenser copper coil (less refrigerant charge, smaller/lighter footprint, enhanced reliability)
• PlusOne Expanded Valve Space (3–4–5 in service valve area, minimum 27 sq in working space)
• PlusOne Triple Service Access (15 in wide corner access, removable corner and louver panels)
• Composite base pan, powder-coated paint, rust-resistant screws, external gauge ports, service trays
• R-454B refrigerant; non-communicating controls
• ENERGY STAR rated
• Height: 35 in
• Width: 33.75 in
• Depth/Length: 33.75 in
• Operating weight: ~248 lb

Gas Furnace (R801V0754A17UHSCAP)

• 80% AFUE single-stage heating
• Constant-CFM variable-speed ECM blower motor for better humidity control, quieter operation, and consistent airflow
• Direct Spark Ignition (PlusOne Ignition System)
• PlusOne Diagnostics with EcoNet/Bluetooth connectivity for easier setup, monitoring, and troubleshooting via Rheem Contractor App (DIP-switch-free commissioning)
• Fully insulated blower cabinet and solid bottom for quieter performance
• Upflow/horizontal configuration, 17.5″ cabinet width
• Standard NOx
  
• Height: 34 in
• Width: 17.5 in
• Depth: ≈29.59–29-11/16 in
• Approximate shipping weight: 118–125 lb

Benefits

• More consistent indoor temperatures and superior humidity control from the two-stage compressor and variable-speed blower
• Quieter outdoor and indoor operation
• Lower energy use compared with older single-stage systems (16 SEER2 cooling efficiency)
• Easier installation and service thanks to expanded valve space, triple service access, Bluetooth diagnostics, and multi-position coil
• Environmentally friendlier low-GWP R-454B refrigerant
• Reliable performance with solid warranty coverage (typically 10-year conditional parts with registration; heat exchanger longer on the furnace)
• Flexible installation options (multi-position coil and upflow/horizontal furnace)

This combination delivers a balanced, modern Rheem system focused on comfort, efficiency, and serviceability for a typical 4-ton residential application.
