Goodman ar9s800804bx 80 Afue Gas Furnace 80000 Btu/h

Product Description

The GOODMAN ar9s800804bx is an 80 AFUE single-stage, multi-speed ECM gas furnace rated at 80,000 BTU/h input and 64,000 BTU/h output. It is configured for upflow or horizontal installation in ducted residential and light-commercial systems. The unit delivers up to 1,089 cubic feet per minute of airflow at high fire and operates on 115 volts, single-phase, 60 Hz power. A Low NOx burner design reduces nitrogen oxide emissions, and the gas heat exchanger pairs with a 10-inch by 8-inch multi-speed blower. Licensed HVAC technicians install this furnace as the primary heating component in forced-air systems sized for up to 4 tons of matched cooling capacity.

The ar9s800804bx is intended for indoor ducted applications in upflow or horizontal configurations. With a cabinet width of 17.5 inches, it fits standard air-handler closets and utility rooms where space is a consideration. The 4-ton nominal cooling capacity rating makes it compatible with matched split-system condensing units in residential and multi-family construction. The multi-speed ECM blower motor allows the system to stage airflow for both heating and cooling modes, supporting comfort and efficiency across varying load conditions. Installation in upflow orientation is the most common field application, though horizontal mounting is supported for attic or crawl-space installations.

Compatibility

Designed for ducted upflow and horizontal forced-air systems with up to 4-ton nominal cooling capacity. The 17.5-inch cabinet width is compatible with standard coil cabinets and air-handler enclosures sized for that dimension. No specific model compatibility data beyond what is stated in the product input is available.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer instructions. Disconnect all electrical power at the breaker and shut off the gas supply at the manual shutoff valve before beginning any work on the unit. Minimum circuit ampacity is 12.45 amps with a maximum overcurrent protection of 15 amps; verify the dedicated circuit meets these requirements before energizing. Observe IFGC requirements for gas line sizing, venting, and combustion air when commissioning the unit in the field.
