The Goodman GR9S800804BX is built for residential heating systems that need substantial heating capacity without a complicated operating setup. It pairs an 80,000 BTU input with single-stage gas heating, an 80% AFUE rating, and a nine-speed ECM blower. The Low NOx configuration is another key feature for applications where reduced nitrogen oxide emissions are an equipment requirement.
Goodman GR9S800804BX Overview
The Goodman GR9S800804BX is an 80000 BTU Gas Furnace designed for upflow and horizontal configurations. Its combination of a single-stage gas valve and nine-speed ECM blower keeps the heating operation straightforward while providing several airflow settings.
As a Goodman 80% AFUE Furnace, this unit is part of the brand's standard-efficiency furnace range. The 80% AFUE rating indicates how effectively the furnace converts its fuel input into usable heat over a typical heating season.
The 17.5-inch cabinet gives this configuration a different airflow profile from narrower and wider models within the GR9S80 family. Its upflow/horizontal design also makes it suitable for compatible ducted system layouts requiring either orientation.
Key Features of This Goodman Single Stage Gas Furnace
The Goodman Single Stage Gas Furnace focuses on straightforward heating operation while using an ECM blower for more flexible airflow control.
-
80,000 BTU Input: Provides substantial residential heating capacity.
-
80% AFUE Rating: Places the furnace within Goodman's standard-efficiency lineup.
-
Single-Stage Heating: Operates at one rated gas heating stage.
-
Nine-Speed ECM Blower: Offers multiple available airflow settings.
-
Low NOx Design: Configured to reduce nitrogen oxide emissions.
-
Upflow / Horizontal Configuration: Supports two common furnace orientations.
-
17.5-Inch Cabinet: Provides a mid-size cabinet within the GR9S80 furnace family.
A Goodman Nine Speed ECM Furnace gives the system multiple blower-speed options instead of relying on a basic fixed-speed blower. This can be useful when matching furnace airflow with compatible indoor and cooling equipment.
