New split-system air conditioners installed in Florida must meet at least 14.3 SEER2 under 45,000 BTU and 13.8 SEER2 from 45,000 to 65,000 BTU. Higher ratings cost more up front and less to run.
What SEER2 means
SEER2 measures how much cooling a system delivers for the electricity it uses over a season, tested under conditions closer to real homes than the older SEER rating. A higher number means lower running costs.
The Florida minimums
- Split-system AC under 45,000 BTU (under about 3.75 tons): at least 14.3 SEER2.
- Split-system AC from 45,000 to 65,000 BTU: at least 13.8 SEER2.
Florida is in the Southeast region, so these regional minimums apply to new split-system air conditioners installed here.
How to choose above the minimum
In Southwest Florida an air conditioner runs most of the year, so efficiency pays back faster than up north. Variable speed systems also remove more humidity and run quieter. If you want the FPL rebate, the new system must be 15.2 SEER2 or higher.
Size matters as much as SEER2
A high-efficiency system that is the wrong size still struggles. An undersized unit runs nonstop on hot afternoons; an oversized one cycles too fast and leaves the house clammy. We size every system to the home.
Quick answers
What is the minimum SEER2 in Florida?
14.3 SEER2 for split-system air conditioners under 45,000 BTU, and 13.8 SEER2 from 45,000 to 65,000 BTU.
Is a higher SEER2 worth it in Naples?
Often yes, because systems here run most of the year. We show you the options side by side.
Does SEER2 affect the FPL rebate?
Yes. The FPL rebate requires a 15.2 SEER2 or higher system on a full replacement through a participating contractor.
