Goodman R-32 Two-Stage Gas Furnace & AC Systems

Shop Goodman R-32 gas systems with a two-stage furnace. A two-stage furnace runs on a lower heat setting most of the time and switches to high only on the coldest days. That means quieter running, fewer hot and cold spots and longer, gentler cycles.

Every system is AHRI-matched and includes three Goodman components: an R-32 air conditioner condenser (GLXS3, GLXS4 or GLXS5), a gas furnace, and a matching cased evaporator coil.

1,070 systems are available (460 upflow, 398 horizontal, 212 downflow), 1.5 to 5 ton, with furnaces from 40,000 to 120,000 BTU and 13.4 to 16.0 SEER2.

Upflow, horizontal or downflow?

• Upflow: the furnace sits in a basement or closet and pushes air up into ducts above it.
• Horizontal: the furnace lies on its side in an attic or crawlspace, with air moving sideways.
• Downflow: the furnace sits in a closet or upper floor and pushes air down into ducts under the floor, common in homes on a slab.

Match the system to the way your current furnace is installed.

Example: GR9S800603BN

• GR = upflow/horizontal, GD = downflow/horizontal
• 9S = single-stage, 9T = two-stage
• 80 / 92 / 96 = AFUE efficiency
• 060 = 60,000 BTU input
• B = cabinet width (A 14", B 17.5", C 21", D 24.5")

Frequently asked questions

Do I need a special thermostat?

A two-stage thermostat gets the most from the furnace, but most Goodman two-stage furnaces can also be set to stage up on their own with a single-stage thermostat. Check the furnace manual.

What refrigerant do these systems use?

R-32. Replace the outdoor unit and the indoor coil together; an R-32 condenser cannot run with an old R-410A or R-22 coil.

Does SEER2 depend on the furnace and coil?

Yes. The SEER2 rating belongs to the exact AHRI-matched combination of condenser, coil and furnace, which is why the same condenser can show different ratings.

Can I use propane?

These furnaces ship set up for natural gas. Most can be converted to propane (LP) with a Goodman conversion kit, sold separately.

Do you ship gas systems?

Yes, to all 48 contiguous states. Licensed contractors can get trade pricing through our contractor portal.
