2.5 Ton Goodman R-32 Gas Furnace & AC Systems

Shop every 2.5 ton Goodman R-32 gas furnace and air conditioner system. A 2.5 ton system typically suits about 1,200–1,500 sq ft, depending on climate, insulation and windows. For the right size, have a Manual J load calculation done.

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.

770 systems are available (352 upflow, 314 horizontal, 104 downflow), with furnaces from 40,000 to 100,000 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.

Frequently asked questions

How do I pick the furnace BTU?

The AC tonnage sets the cooling size; the furnace BTU sets heating. For a 2.5 ton system you can choose 40,000, 60,000, 80,000 or 100,000 BTU. Colder climates and larger homes need more BTU. The furnace blower must also be rated for the AC size, which every matched kit here already is.

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.
