The Goodman GR9S800805CN combines an 80,000 BTU heating input with a high-airflow blower configuration for residential ducted systems. This model features 80% AFUE efficiency, single-stage gas heating, and a nine-speed ECM blower capable of supporting up to 2,000 CFM. Its 21-inch cabinet and upflow/horizontal configuration make it a distinct option within the GR9S80 furnace family.
Goodman GR9S800805CN Overview
The Goodman GR9S800805CN is an 80000 BTU Gas Furnace built for systems requiring substantial heating capacity along with higher airflow capability. Its single-stage gas valve provides straightforward heating operation, while the ECM blower offers multiple airflow settings.
As a Goodman 80% AFUE Furnace, the unit is rated to convert approximately 80% of its fuel input into usable heating output. With an 80,000 BTU input rating, that corresponds to approximately 64,000 BTU of heating output.
One of the most useful distinctions of this configuration is its blower capacity. The furnace supports up to 2,000 CFM and uses a 21-inch-wide cabinet, making airflow capability an important consideration when comparing it with other 80,000 BTU models in the GR9S80 series.
