Complete Systems

A complete system is an AHRI-certified matched pair: the Goodman outdoor unit and the indoor equipment it was rated with, sold together so the SEER2 on the label is the SEER2 you actually get. Every combination here is R-32, in stock in Winder, Georgia, and ships free. There are 4,495 of them, so start with the layout that matches your house.

Pick your system type

Have gas and need both heating and cooling?

Air conditioner + furnace systems (3,082 combinations) are the classic split system: a gas furnace indoors that moves the air year-round, an air conditioner outdoors. For colder climates or the lowest heating bills, heat pump + furnace systems (1,078) run the heat pump in mild weather and hand off to the furnace when it gets cold.

All-electric home?

Heat pump + air handler systems (80) heat and cool from one package with an electric heat kit for backup. Air conditioner + air handler systems (158) are cooling-only unless you add a heat kit.

Keeping a working furnace?

Air conditioner + coil systems (97) replace only the cooling side: a new condenser and a matched coil that sits on the furnace you already own.

Then pick a size

Residential systems run from 1.5 to 5 tons (18,000 to 60,000 BTU/h of cooling). As a rule of thumb in a moderate climate that is roughly 600 to 900 square feet for 1.5 tons up to 2,400 to 3,000 for 5 tons — but insulation, windows, ceiling height and duct condition move the answer, so run a load calculation or use our free HVAC system sizing tool before you buy. Each system-type page above is organised by size with starting-point combinations for every tonnage.

Reading the efficiency numbers

SEER2 is cooling efficiency under the Department of Energy’s 2023 test; higher is cheaper to run, and the matched-system SEER2 is usually higher than the condenser rated alone. AFUE is furnace efficiency: 80% furnaces vent through a metal flue, 92% to 97% condensing furnaces vent in PVC and need a condensate drain. HSPF2 is heat-pump heating efficiency. Every listing shows its AHRI certificate number so you can confirm the rating for rebates and inspection.

What’s in the box

The components named on the product page and nothing else. Line set, thermostat, pad, disconnect and electric heat kits are sold separately; R-32 systems must be installed by a licensed contractor. Goodman residential equipment carries a 10-Year Parts Limited Warranty when registered within 60 days of installation.
