4 Ton Rheem 16 SEER2 R-454B 80% AFUE 100,000 BTU Two-Stage Variable Speed Upflow/Horizontal Gas Furnace Split System

This is a matched Rheem/Ruud Endeavor Line residential system using low-GWP R-454B refrigerant. It pairs a 4-ton two-stage air conditioner condenser with a multi-position cased evaporator coil and an 80% AFUE single-stage gas furnace with a variable-speed (constant CFM) ECM blower. The combination delivers efficient cooling with good humidity control and reliable heating, suitable for many homes needing 48,000 BTU cooling and 80,000–100,000 BTU heating capacity.

When properly matched and installed, this combination provides solid SEER2 cooling efficiency (typically in the mid-teens depending on exact AHRI match), reliable 80% AFUE heating, and modern features focused on comfort, quieter operation, and serviceability. Always verify the specific AHRI-rated match for exact efficiency numbers, confirm local code compliance (including A2L refrigerant requirements), and have a qualified technician size and install the system. Dimensions and weights are approximate based on manufacturer data.
