Wrangler WR-GD9T960603BN Gas Furnace vs Goodman GR9S800603BN Gas Furnace

The Wrangler WR-GD9T960603BN is the better furnace on paper: 96% AFUE, two-stage gas valve, multi-speed ECM blower and a 34-1/2 in cabinet that fits downflow or horizontal closets. The Goodman GR9S800603BN is a basic 80% single-stage upflow/horizontal unit with a standard PSC-style blower and a simpler control board. Buy the Wrangler if you want lower gas use, steadier temperatures and quieter low-fire operation; buy the Goodman if your ductwork is upflow and you want a straightforward, widely serviced furnace. Owners of two-stage ECM furnaces generally report more even heat and less cycling; single-stage 80% units are simpler and cheaper to repair but run at full fire every cycle.

• Choose the Wrangler WR-GD9T960603BN if you have a downflow or horizontal closet, want 96% AFUE and two-stage comfort, and plan to stay in the home long enough for the efficiency to matter.
• Choose the Goodman GR9S800603BN if your installation is upflow, your budget favors a simple single-stage furnace, and you want a common unit that most local technicians know well.
