Features
- Advanced Heat Exchanger Design
- The GMS8 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.
- Quiet Comfort
- The blower, motor, and igniter of the GMS80403AN were selected for their incredibly low sound levels.
- Secure Cabinet
- All GMS8 furnaces are protected by a durable steel cabinet with a long-lasting powder paint finish. The heat exchanger section is lined with foil-insulation to prevent heat loss and the entire cabinet is rated for less than 2% air leakage.
- Easy Integration
- The GMS80403AN makes it simple to enhance your system with a humidifier; just wire it directly to the low-voltage terminal on the control board.
- 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.
