The Goodman GR9T800603AN is a high-efficiency, two-stage gas furnace designed for residential heating. It provides 60,000 BTUs of input capacity with an 80% AFUE rating, meaning 80% of the fuel energy is converted into usable heat. It’s engineered for quiet, reliable performance and can be installed in upflow or horizontal configurations, making it suitable for a wide range of homes.

This model features a two-stage gas valve that operates at a lower stage during mild weather and a higher stage during colder temperatures, enhancing comfort and efficiency. A 9-speed ECM blower motor helps maintain consistent airflow while reducing energy use and noise.

Ideal for homeowners looking for dependable, cost-effective heating with some of the benefits of higher-end models—such as multi-stage operation—without the full cost of ultra-high-efficiency furnaces.
