IMPORTANT: HVAC and Water Heater parts and accessories should only be installed by qualified technicians.

It is your responsibility to seek professional advice when installing and using these parts and accessories.

Goodman HVAC Systems - Affordable, Energy-Efficient Air Conditioners & Heat Pumps Made in the USA.

Goodman is one of America's most trusted HVAC brands, offering energy-efficient air conditioners, heat pumps, and gas furnaces for reliable residential heating and cooling. Every Goodman system is USA-assembled, ISO 9001-certified, and backed by an industry-leading 10-Year Parts & Unit Replacement Limited Warranty.

This furnace combines two-stage heating with a nine-speed ECM blower motor. It supports upflow and horizontal orientations and provides nominal airflow for compatible cooling equipment from 2.5 to 4 tons.

The Goodman GR9T800804BN gas furnace has an 80,000 BTU maximum input and provides approximately 64,000 BTU of heating output. Its 17.5-inch cabinet contains a 3/4 HP blower rated at 1,600 nominal CFM.

A Goodman 80000 BTU gas furnace may suit medium-sized properties with heating requirements matched to this capacity. Climate conditions, insulation and the building’s heat-loss calculation determine the correct furnace size.

The Goodman nine-speed ECM furnace provides several factory-selected airflow settings. These settings allow the blower to support heating, matched cooling equipment and continuous air circulation.

Goodman GR9T800804BN Overview

The Goodman GR9T800804BN gas furnace operates at 56,000 BTU input on its lower stage and 80,000 BTU on high fire. The two available stages allow the unit to respond to mild and heavier heating demand.

An 80% AFUE gas furnace converts approximately 80% of its annual fuel consumption into usable indoor heat. Combustion gases and the remaining heat exit through the required metal flue.

A Goodman two-stage furnace can spend more time operating at reduced output during moderate weather. Full capacity becomes available when colder conditions create a greater demand for heat.

The Goodman 80000 BTU gas furnace uses a heavy-duty aluminized-steel tubular heat exchanger. A silicon nitride igniter starts each cycle electronically, without relying on a standing pilot light.

Key Features of Goodman 80,000 BTU Gas Furnace

The Goodman GR9T800804BN gas furnace pairs staged heat control with a higher-airflow blower in a 17.5-inch B-size cabinet.

  • 80,000 BTU maximum heating input

  • 64,000 BTU maximum output

  • 56,000 BTU low-stage input

  • 45,000 BTU low-stage output

  • Two-stage gas valve

  • Nine-speed ECM blower motor

  • 3/4 HP motor rating

  • 1,600 CFM nominal airflow

  • Up to 1,708 CFM at 0.5-inch external static pressure

  • Cooling airflow range from 2.5 to 4 tons

  • Upflow or horizontal configuration

  • Aluminized-steel tubular heat exchanger

  • Silicon nitride hot-surface igniter

  • Self-diagnostic control board

  • Continuous-fan airflow setting

  • R-32 refrigerant-system compatibility

  • Natural gas operation with propane conversion capability

  • Metal flue venting requirement

The Goodman nine-speed ECM furnace offers more airflow choices than a basic single-speed blower. And ECM technology uses less electricity than a traditional permanent-split capacitor motor under comparable operating conditions.

A Goodman two-stage furnace avoids using full heat output during every cycle. Lower-stage operation can provide gentler temperature changes and longer heating cycles during milder weather.

The Goodman GR9T800804BN gas furnace uses a B-size cabinet with a 17.5-inch width. Its upflow, horizontal-left and horizontal-right orientations support several common equipment layouts.

Who Should Buy This Goodman Furnace?

The Goodman GR9T800804BN gas furnace may suit medium-sized homes or buildings with heating loads close to its 80,000 BTU input. Its blower can support compatible cooling equipment requiring up to four tons of nominal airflow.

An 80% AFUE gas furnace may fit properties that already have suitable metal flue venting and combustion-air provisions for non-condensing equipment.

The Goodman 80000 BTU gas furnace may be appropriate for:

  • Properties with moderate-to-high heating requirements

  • Systems requiring a 17.5-inch cabinet

  • Compatible cooling equipment from 2.5 to 4 tons

  • Upflow or horizontal equipment layouts

  • Buyers who prefer two-stage heating

  • R-32-compatible HVAC systems

The Goodman GR9T800804BN gas furnace should be selected using the property’s heat-loss calculation and available duct capacity. An oversized furnace can create short cycles and uneven temperatures.
