Our take on the Goodman Furnace GM9C800603BX

The Goodman GM9C800603BX is a single-stage, 80% AFUE gas furnace rated at 60,000 BTU input. It runs on natural gas and can be converted to propane with an LP kit. It is a builder-grade unit aimed at budget-minded replacements and mild-climate homes where a condensing furnace's extra efficiency would not pay back. Against 90%+ condensing rivals it is simpler and cheaper to install, but it vents through a metal flue and wastes more heat up the chimney.

Questions and answers

Is this furnace 80% or 90% efficient?
It is an 80% AFUE furnace. It vents through a standard metal flue and does not condense, so it is less efficient than 90%+ models.
Can it run on propane?
Yes. It ships set up for natural gas and needs an LP conversion kit to run on propane.
What size home does 60,000 BTU suit?
It suits smaller homes or mild climates. A load calculation is the only reliable way to size a furnace.
Does it need a special vent?
No. It uses a standard metal flue rather than PVC, which simplifies replacement of an older 80% furnace.
Is it a single-stage or two-stage furnace?
It is single-stage. It runs at one full output level and shuts off when the thermostat is satisfied.
Can I install it myself?
No. Gas furnace installation requires a licensed HVAC contractor and permits in most areas.
