The Goodman GR9T800803BN is built for homes that need substantial heating capacity with more control than a basic single-stage furnace can provide. Its 80,000 BTU input capacity is paired with an 80% AFUE rating, two-stage gas operation, and a nine-speed ECM blower motor. Together, these features give homeowners a straightforward furnace designed around steady heating and controlled airflow.
Goodman GR9T800803BN Overview
The Goodman GR9T800803BN is an 80000 BTU Gas Furnace designed for residential heating applications. It provides approximately 64,000 BTU of heating output from its 80,000 BTU input capacity.
As a Goodman 80% AFUE Furnace, the unit converts approximately 80% of its fuel input into usable heat. The remaining portion is associated with combustion losses through the venting process.
One of the main differences between this furnace and a basic model is its two-stage gas valve. Rather than operating at full heating capacity every time there is a call for heat, the furnace can use a lower stage during lighter heating demand and move to the higher stage when more output is required.
The nine-speed ECM blower motor adds another level of airflow control by providing multiple selectable airflow settings.
Key Features of Goodman Two Stage Gas Furnace
The Goodman Two Stage Gas Furnace combines substantial heating capacity with a design intended to provide more controlled operation.
-
80,000 BTU Input Capacity: Provides approximately 64,000 BTU of heating output.
-
80% AFUE Rating: Converts roughly 80% of fuel input into usable heating.
-
Two-Stage Gas Valve: Allows the furnace to operate at different heating levels depending on demand.
-
Nine-Speed ECM Motor: Provides multiple airflow settings for more flexible blower operation.
-
Upflow or Horizontal Configuration: Supports more than one equipment orientation.
-
115V Power: Uses a standard single-phase furnace electrical configuration.
-
Compact Cabinet: The 17.5-inch cabinet width helps the furnace fit within many ducted HVAC layouts.
For buyers comparing a Goodman Nine Speed ECM Furnace, the blower design is an important feature because airflow can be matched more precisely to the needs of the overall HVAC system.

GR9T800803BN Dimensions & Heating Capacity
The furnace measures approximately 17.5 in, 28 inches deep, and 33.375 inches high. Its listed weight is about 118 pounds.
Heating capacity is based on an 80,000 BTU input rating. With 80% AFUE efficiency, the furnace provides approximately 64,000 BTU of usable heating output.
That does not mean an 80% AFUE Gas Furnace with this capacity is automatically right for every home. Heating requirements vary according to climate, insulation, window area, ceiling height, air leakage, building size, and other characteristics.
The relatively narrow 17.5-inch cabinet can also be useful when the furnace needs to coordinate with compatible indoor HVAC components.
Who Should Buy This 80,000 BTU Goodman Furnace?
This Goodman 80000 BTU Gas Furnace is suited to buyers whose property requires a furnace within this heating-capacity range and who want two-stage operation rather than a basic single-stage design.
It may be appropriate for:
-
Homes requiring around 80,000 BTU of furnace input capacity
-
Properties where an 80% AFUE furnace is suitable
-
Buyers who want two-stage heating operation
-
HVAC systems that benefit from a nine-speed ECM blower
-
Upflow furnace configurations
-
Horizontal furnace configurations
-
Systems using compatible ducted cooling equipment
-
Buyers looking for a 17.5-inch-wide furnace cabinet
The benefit of a Two Stage Gas Furnace is that it does not need to operate at maximum heating output during every heating cycle. Lower-stage operation can handle lighter demand, while the second stage is available when additional heat is needed.
