Is a 4 ton AC the right size for your home?

A 4 ton air conditioner moves 48,000 BTU of heat out of your home every hour. In Florida that typically fits about 2,100 to 2,400 square feet. It is common in four-bedroom homes, two-story homes on one system and larger Venice, Sarasota and Cape Coral pool homes.

At 48,000 BTU, a 4 ton system crosses the 45,000 BTU/h line, so the Florida minimum drops to 13.8 SEER2. Larger homes also bring duct questions: a 4 ton system needs ductwork that can move roughly 1,600 CFM. Undersized return air is the most common reason a new 4 ton unit underperforms.

Square footage is only a starting point. A Manual J load calculation accounts for insulation, window area and orientation, ceiling height, duct location and how many people live in the home. If your load calculation comes in lower, the 3.5 ton system covers 1,800 to 2,100 sq ft. If it comes in higher, step up to the 5 ton system (2,400 to 3,000 sq ft). Not sure? Use our sizing guide or call us with your square footage and the model number from your old unit.

4 ton AC unit price

Our price for the 4 ton Goodman system is below the manufacturer's advertised minimum, so it appears in your cart: add the system above to see it, with no obligation. That price covers the condenser and air handler only. A full replacement also includes labor, a mechanical permit, refrigerant line set, a condenser pad, an electrical disconnect and whip, a float switch and removal of the old unit. Our AC unit cost guide breaks those costs down.

Larger systems cost less per ton of cooling, so compare price per ton when you are choosing between two sizes.

Want heating too? See the Goodman 4 ton R-32 heat pump. It uses the same AMST48CU1300 air handler.

Florida minimums come from the DOE Southeast regional standard: split air conditioners under 45,000 BTU/h need 14.3 SEER2, and those at or above 45,000 BTU/h need 13.8 SEER2. Read our Florida SEER2 guide for details.

Frequently asked questions

How many square feet does a 4 ton AC cool?
In Florida a 4 ton (48,000 BTU) system typically covers about 2,100 to 2,400 sq ft. Confirm with a Manual J load calculation, and have the ductwork checked, because a 4 ton unit needs roughly 1,600 CFM of airflow.
What is the minimum SEER2 for a 4 ton AC in Florida?
13.8 SEER2. Split air conditioners at or above 45,000 BTU/h installed in the Southeast region must meet at least 13.8 SEER2. Our Goodman 4 ton system (GLXS4BA4810 + AMST48CU1300) is AHRI-certified at 14.0 SEER2.
How many BTU is a 4 ton air conditioner?
48,000 BTU per hour.
Is one 4 ton system or two smaller systems better for a two-story home?
Two zones or two systems usually control a two-story Florida home better, because heat rises and the upstairs runs hotter. A single 4 ton system can work with good duct design and zoning. A load calculation per floor gives the answer.
