Features
- Advanced Heat Exchanger Design
- The GM9S80-U furnace employs a reliable dual-diameter tubular heat exchanger design. Aluminized steel is used for incredibly efficient heat transfer, and a wrinkle-bend is applied to the tubes to enhance the heat exchanger's dependability and longevity.
- Multi-Speed ECM Motor
- The GM9S80-U's energy efficient blower motor uses the lowest speed it can to deliver precise temperature control for your home while keeping utility bills to a minimum.
- Quiet Comfort
- The blower and gas valve of the GM9S80-U were selected for their incredibly low sound levels. Additionally, this unit offers an airflow system and fan speed options that allow it to operate quietly while providing consistent comfort.
- Secure Cabinet
- All GM9S80-U furnaces are protected by a durable steel cabinet rated for less than 2% air leakage. The heat exchanger section is insulated to prevent heat loss and the return side of the cabinet is solid and airtight.
- Self-Diagnostic Control Board
- The GM9S80-U continuously monitors the system to ensure reliable operation, stores the last diagnostic codes in memory, and a flashing LED indicates condition for quick troubleshooting.
- Extended Warranty
- Goodman offers a 10-year limited parts warranty when you register your product online within 60 days of installation. An unregistered product has the standard 5-year warranty. See warranty sheet under the "Manuals" tab for more information.
- Ultra Low Nox
- California state law requires that every newly installed furnace emits less than 14 ng/J of NOx gases, a toxic byproduct of combustion. Goodman GM9S80-U furnaces feature Ultra Low NOx emissions, conforming to this regulation.
Goodman's GM9S80-U furnaces feature high-quality construction and efficient operation at a great value. The GM9S80-U single-stage, multi-speed furnaces utilizes Goodman's superior heat exchanger design to provide efficient, reliable heating to your home. Instead of a standard multi-speed blower motor, the GM9S80-U utilizes an ECM motor, which uses less power and provides smarter circulation. The value doesn't end at efficiency, the GM9S80-U features many different connection options to reduce installation time and a self-diagnosing control board to expedite maintenance. If you're looking to cut your energy bills and improve your comfort without breaking the bank, your search stops with the GM9S80-U.

Fuel Type
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Vent Type
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Chimney Vent
Modulating/Staging
Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Ultra Low NOx Emissions
Ultra Low NOx Emissions
NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More
