TL;DR: SEER2 is the efficiency score on a new central air conditioner, and a bigger number means the same cooling for less electricity.

Florida sits in the federal Southeast region, so every new central AC installed here must meet 14.3 SEER2 (the U.S. Department of Energy minimum for split-system units under 45,000 BTU under its 2023 standard, equivalent to about 15 SEER under the prior test method). Heat pumps must hit 14.3 SEER2 / 7.5 HSPF2 nationally. Air…
