Goodman furnaces only come in a gas variety. Five out of the eleven Goodman gas furnaces are Energy Star compliant and they have an AFUE rating between 95 percent and 80 percent. Like all gas furnaces, dust and dirt can create problems inside of a Goodman furnace if allowed to build up. The build up affects the effectiveness of the furnace over time. Cleaning the Goodman furnace at least once a year allows it to work effectively at heating your home.


Step 1

Turn off the Goodman gas furnace and turn off the gas line that runs to the furnace. Open the maintenance hatch.

Vacuum out the circular blowers, the draft regulator and the flue passages on the Goodman furnace.

Vacuum around the Goodman furnace to prevent more dust from entering. Close the maintenance hatch and turn the gas and power to the furnace back on.
