Our take on the Goodman 100,000 Btu 80% Afue 9 Speed Two-Stage Upflow Gas Furnace for use with R-32 Refrigerant (2,000 CFM)

The Goodman GR9T8 is a two-stage, 9-speed upflow gas furnace rated at 100,000 Btu input and 80% AFUE, built for use with R-32 refrigerant coils. Its two-stage burner and variable-speed blower deliver steadier heat and quieter, more even airflow than a single-stage furnace, and the multi-speed blower also helps with humidity control in summer cooling. At 80% AFUE it sits below high-efficiency condensing models, so it suits homes where venting a condensing furnace is impractical or where a standard chimney flue already exists. It is a solid value pick against comparable two-stage furnaces from Carrier, Trane and Lennox, though it lacks their premium sound packages and longer standard warranties.

Best forReplacing an older 80% furnace in a home with an existing metal flueHomeowners wanting two-stage comfort without condensing-furnace venting workHomes needing roughly 2,000 CFM of airflow for a large duct systemBuyers pairing a furnace with an R-32 air conditioner or heat pump coil
Pros
  • Two-stage burner runs mostly on low fire for steadier temperatures
  • 9-speed blower supports better airflow balance and summer humidity control
  • Upflow cabinet fits standard closet and basement installations
  • Designed for R-32 refrigerant coils, matching newer cooling equipment
  • Assembled in the United States with widely available parts
Cons
  • 80% AFUE is less efficient than 90%+ condensing furnaces
  • 100,000 Btu input is oversized for small or well-insulated homes
  • Two-stage control needs a compatible two-stage thermostat to get full benefit
  • Variable-speed blower boards are costlier to replace than basic motors
  • Standard warranty is shorter than some premium brands offer

Questions and answers

Is this furnace worth it over a single-stage model?
Yes, if you want steadier heat and quieter airflow. The two-stage burner and 9-speed blower cost more up front but improve comfort over a basic single-stage furnace.
Does it work with R-32 refrigerant equipment?
Yes. It is designed for use with R-32 refrigerant coils, so it pairs with newer R-32 air conditioners and heat pumps.
What size home suits 100,000 Btu?
It fits larger homes or homes with significant heat loss, roughly in the 2,500 to 3,500 square foot range depending on climate and insulation. A load calculation should confirm the size.
Can I use my existing thermostat?
A single-stage thermostat will run it, but you need a two-stage thermostat to get low-fire and high-fire operation and the full comfort benefit.
Is it a condensing furnace?
No. At 80% AFUE it is a non-condensing furnace that vents through a standard metal flue, not PVC pipe.
What is in the box?
The furnace cabinet itself. The coil, thermostat, venting and installation materials are separate.
