4 Ton Rheem 16 SEER2 R-454B 96% AFUE 100,000 BTU Two-Stage Variable Speed Multi-Position Gas Furnace Split System

This is a Rheem high-efficiency, matched 4-ton residential split system designed for reliable year-round comfort. It pairs a 16 SEER2 two-stage air conditioner (R-454B refrigerant) with a multi-position N-coil and a 96% AFUE two-stage variable-speed gas furnace. The Rheem combination delivers precise temperature control, strong humidity management, quieter operation, and energy savings while using lower-GWP R-454B refrigerant.
