Natural Gas or LP Furnace|
From the factory, the GD9S800804BX runs on natural gas. However all Goodman gas furnaces can be converted to propane using the furnace's corresponding LP conversion kit, an optional accessory at an additional cost that consists of a replacement set of orifices and springs.

Multi-Speed ECM Blower Motor
Instead of the last generation PSC blower motor, the GD9S800804BX utilizes a multi-speed ECM motor, which uses less power and provides smarter air circulation. All of this causes an overall increase in the electrical efficiency of your furnace, which saves you money.

Warranty
With installation that follows your state and local codes and with online registration, all Goodman furnaces come with a 10-year parts and lifetime heat exchanger warranty through the manufacturer.

Durable Hot Surface Igniter
The hot surface igniter on modern Goodman furnaces are more durable than previous designs, decreasing related issues and lowering maintenance costs. These hot surface ignitors are also more efficient than standing pilot and older HSI designs, saving you even more money.

Self-Diagnostic Control Board
The Goodman brand has improved technology from years of production experience, allowing for a long-lasting product that rarely has any issues. However, if something does go wrong on the furnace, the control board has a set of sensors that allow it to diagnose basic issues, allowing for easy troubleshooting and to notify the owner if basic maintenance or warranty work is recommended. This increases the overall safety of the unit, for the furnace itself and the occupants of the home where it is installed.

Heavy Gauge Steel Cabinet
The heavy-gauge steel cabinet on new Goodman furnaces provide adequate protection to the internal mechanisms of the unit. The cabinet is also more air-tight than previous models, allowing for a quiet, more economical unit due to losing less heat and preventing more sound from exiting the unit.

Ease of Installation
The value of modern Goodman furnaces doesn't end at efficiency. Today's Goodman furnaces feature many different connection options to reduce installation. The GD9S800804BX model has a more universal design, which consists of its ability to be installed in both an downflow or horizontal (left or right) configuration. This allows for an easier installation in more locations, from your attic to your basement. The furnace also comes with color-coded low-voltage terminals that allow for a shorter and easier installation time, which decreases installation costs.
