Goodman 80,000 BTU 80% AFUE Gas Furnace Two-Stage GR9T800803BN

 

The Goodman GR9T800803BN is an 80,000 BTU gas furnace designed to deliver dependable heating, improved comfort, and efficient operation for residential applications. With an 80% AFUE rating, this furnace converts up to 80% of the fuel it consumes into usable heat, making it an excellent choice for homes in regions where an 80% efficient furnace is appropriate.

Unlike traditional single-stage furnaces, the GR9T800803BN features a two-stage gas valve that operates at a lower heating capacity during milder conditions and automatically increases to full capacity when additional heat is needed. This staged operation helps maintain more consistent indoor temperatures, reduces temperature swings, operates more quietly, and can improve overall comfort throughout the heating season.

Engineered for long-lasting reliability, the GR9T800803BN utilizes a heavy-duty aluminized steel tubular heat exchanger designed for dependable performance and durability. The multi-speed ECM blower motor automatically adjusts airflow to improve comfort while using less electricity than a standard PSC blower motor. Continuous fan operation is also available to help circulate air throughout the home between heating cycles, promoting more even temperatures and improved indoor air circulation.

Designed with both installers and homeowners in mind, the GR9T800803BN features a self-diagnostic control board with LED fault code display and color-coded low-voltage terminals to simplify installation, maintenance, and troubleshooting. The control platform also supports compatible indoor air quality accessories such as electronic air cleaners and humidifiers, allowing homeowners to enhance their overall comfort system.

Its multi-position cabinet supports upflow, horizontal left, and horizontal right installations, providing installation flexibility for a variety of residential applications. Whether replacing an aging furnace or installing a new HVAC system, the Goodman GR9T800803BN offers an ideal combination of comfort, reliability, and value.
