Ducane 96G2UH Gas Furnace vs Goodman GR9S800603BN Gas Furnace

The Ducane 96G2UH is the better furnace for most homes that can vent through a side wall or roof: its 96% AFUE two-stage burner and variable-speed ECM blower deliver steadier heat, quieter airflow and lower gas use than the Goodman. The Goodman GR9S800603BN is the simpler, cheaper-to-own choice where a standard chimney flue exists and budget or a short run matters more than efficiency. Build-wise both use aluminized-steel primary heat exchangers in a 33-inch cabinet; the Ducane adds a stainless secondary exchanger, which is the part that lifts it to condensing efficiency. Owners and technicians generally rate Goodman as easy to service and widely stocked, while Ducane (a Lennox-owned brand) draws praise for quiet two-stage comfort but has a thinner dealer network.

• Choose the Ducane 96G2UH if you want maximum efficiency, two-stage comfort and a variable-speed blower, and you can vent with PVC pipe through a side wall or roof.
• Choose the Goodman GR9S800603BN if you have a conventional chimney, want a straightforward single-stage furnace that any technician can service, and efficiency is secondary.
