The Goodman GR9T960804CN is a high-efficiency residential natural gas furnace engineered to deliver improved comfort and energy performance. With an 80,000 BTU input capacity and 96% AFUE rating, this condensing furnace extracts additional heat from combustion gases, maximizing fuel efficiency compared to standard-efficiency models.
This two-stage furnace operates at a lower heating capacity during moderate demand and shifts to full capacity during colder conditions. Two-stage operation enhances temperature consistency, reduces system cycling, and supports improved overall comfort.
Designed for upflow or horizontal installation, this model offers flexibility based on mechanical room layout and duct configuration. As a 96% AFUE condensing furnace, it utilizes PVC venting and must be installed according to local building and fuel gas codes.
Professional installation by a licensed HVAC technician is required to ensure correct system sizing, airflow configuration, combustion setup, and code compliance.
