Air Conditioner + Coil Systems

An air conditioner and coil system is the replacement package for a home that already has a working gas furnace: a Goodman outdoor condensing unit plus a matched cased evaporator coil that sits on the furnace and uses its blower. You keep the heating side you already own and replace only the cooling side, which is the lowest-cost route to a new, R-32, AHRI-rated air conditioner.

Every AC and evaporator coil system on this page is sold as an AHRI-certified matched pair — the components are factory-rated together, so the efficiency on the label is the efficiency you get — and ships free from our Winder, Georgia warehouse. 97 combinations are listed; the quickest way through them is by size.

Air Conditioner + Coil Systems by size

2 ton AC and evaporator coil systems

A 2-ton system delivers 24,000 BTU/h of cooling — roughly 900 to 1,200 square feet in a moderate climate as a rule of thumb, before a load calculation. 20 2-ton combinations are in stock; typical starting points: Goodman 2 Ton 13.4 SEER2 AC + Coil · Goodman 2 Ton 14.3 SEER2 AC + Coil.

2.5 ton AC and evaporator coil systems

A 2.5-ton system delivers 30,000 BTU/h of cooling — roughly 1,200 to 1,500 square feet in a moderate climate as a rule of thumb, before a load calculation. 18 2.5-ton combinations are in stock; typical starting points: Goodman 2.5 Ton 13.4 SEER2 AC + Coil · Goodman 2.5 Ton 14.3 SEER2 AC + Coil.

3 ton AC and evaporator coil systems

A 3-ton system delivers 36,000 BTU/h of cooling — roughly 1,500 to 1,800 square feet in a moderate climate as a rule of thumb, before a load calculation. 17 3-ton combinations are in stock; typical starting points: Goodman 3 Ton 13.4 SEER2 AC + Coil · Goodman 3 Ton 14.3 SEER2 AC + Coil.

3.5 ton AC and evaporator coil systems

A 3.5-ton system delivers 42,000 BTU/h of cooling — roughly 1,800 to 2,100 square feet in a moderate climate as a rule of thumb, before a load calculation. 12 3.5-ton combinations are in stock; typical starting points: Goodman 3.5 Ton 13.4 SEER2 AC + Coil · Goodman 3.5 Ton 14.3 SEER2 AC + Coil.

4 ton AC and evaporator coil systems

A 4-ton system delivers 48,000 BTU/h of cooling — roughly 2,100 to 2,400 square feet in a moderate climate as a rule of thumb, before a load calculation. 9 4-ton combinations are in stock; typical starting points: Goodman 4 Ton 13.4 SEER2 AC + Coil · Goodman 4 Ton 13.8 SEER2 AC + Coil.

5 ton AC and evaporator coil systems

A 5-ton system delivers 60,000 BTU/h of cooling — roughly 2,400 to 3,000 square feet in a moderate climate as a rule of thumb, before a load calculation. 6 5-ton combinations are in stock; typical starting points: Goodman 5 Ton 13.4 SEER2 AC + Coil · Goodman 5 Ton 14.5 SEER2 AC + Coil.

How to choose a AC and evaporator coil system

• Tonnage from a load calculation; the coil tonnage must be an AHRI-listed match for the condenser.
• Coil cabinet width and orientation must fit the existing furnace — upflow/downflow or horizontal, and the A/B/C/D cabinet letter.
• Furnace blower capacity: the existing furnace has to move enough air for the new tonnage.
• Refrigerant: every system here is R-32, so the coil and condenser are matched to each other — the old line set and coil cannot be reused.

What ships with a complete system

The components listed on each product page — the outdoor unit, the indoor coil, air handler or furnace — and nothing else. Line set, thermostat, equipment pad, disconnect and any electric heat kit are sold separately, and installation is licensed-contractor work (R-32 is an A2L refrigerant). Goodman residential equipment carries a 10-Year Parts Limited Warranty when registered within 60 days of installation. Not sure which combination fits your house?

Air Conditioner + Coil Systems FAQ

Will the new coil fit my old furnace?

Only if the cabinet width and orientation match and the furnace blower can move the airflow the new tonnage needs. Call with your furnace model number and we will check.

Can I keep my old line set?

Every system here is R-32. Line sets must be R-32 rated, cleaned and sized for the new unit; most replacements run a new set.
