SEER2 is the efficiency rating the U.S. Department of Energy has used for central air conditioners and heat pumps since January 1, 2023. It uses a tougher test than the older SEER rating, so the same unit rates a little lower in SEER2.

What is the minimum in Florida?

Florida is in the Southeast region. A new split-system central air conditioner there must be at least 14.3 SEER2 under 45,000 BTU per hour, or 13.8 SEER2 at 45,000 BTU and above.

Will I really save this much?

Not necessarily. The figure comes only from the numbers you entered. Real use depends on your thermostat, the house, the ducts, how the new system is sized and installed, and the weather.

Where do I find my current rating?

On the yellow EnergyGuide label or the data plate on the outdoor unit, or from the model number. Older systems are rated in SEER; choose SEER and the calculator converts it.

Estimated difference, from your inputs

$529 less a year

3,528 kWh less a year. An estimate from the numbers you entered — not a promise of savings.

How this is worked out. kWh a year = tons × 12,000 × cooling hours ÷ (SEER2 × 1,000), then × your rate. Real use depends on your thermostat setting, the home, the ducts, how the system was sized and installed, and the weather — so treat it as a comparison, not a bill. An older SEER rating is converted to SEER2 at about × 0.953.

We handle AC replacements under our Florida Certified Building Contractor license (CBC1265305). The AC work is performed by our Florida-licensed air-conditioning subcontractors, who pull the permit. AC service is in Miami-Dade, Broward and Palm Beach counties.
