SEER2 in Florida means any new split central air conditioner under 45,000 Btu/h must be rated at least 14.3 SEER2, which is roughly 15 on the old SEER scale. Larger split systems need 13.8 SEER2. Florida is in the federal Southeast region, so these minimums are higher than in northern states. If you are planning a new AC installation, every quote should list the SEER2 number.

Key Takeaways on SEER2 in Florida
- The minimum is 14.3 SEER2. That applies to split AC systems under 45,000 Btu/h installed in Florida since January 1, 2023.
- SEER2 is a tougher test. It uses higher airflow resistance, so a SEER2 number is lower than the old SEER number for the same unit.
- Install date is what counts. The Southeast rule applies to when the system is installed, not when it was built.
- Heat pumps have no regional bump. Split heat pumps need 14.3 SEER2 and 7.5 HSPF2 everywhere in the country.
- Higher is not always better. Payback depends on your usage, your ducts and correct sizing.
What SEER2 Actually Measures
SEER2 stands for Seasonal Energy Efficiency Ratio 2. It tells you how much cooling a system delivers for each unit of electricity over a typical season. A higher number means lower running costs for the same amount of cooling.
The Department of Energy switched from SEER to SEER2 on January 1, 2023. The new test uses higher external static pressure. In plain words, it assumes your ductwork pushes back harder, which is closer to how systems work in real homes. Because of that, the same unit scores lower under SEER2 than it did under SEER.
SEER vs SEER2 in Simple Numbers
A rough rule is that a SEER2 rating runs about 4% to 5% below the old SEER rating. A 14.3 SEER2 system is about the same as a 15 SEER system under the old test. Do not compare a SEER number on one quote with a SEER2 number on another.
The SEER2 Minimums That Apply in Florida
Federal rules split the country into North, Southeast and Southwest regions. Florida falls in the Southeast, which is why SEER2 in Florida is stricter than in Ohio or Michigan. The current figures come from federal efficiency standards in 10 CFR 430.32.
| System type | Florida minimum | Old SEER equal |
|---|---|---|
| Split AC under 45,000 Btu/h | 14.3 SEER2 | About 15 SEER |
| Split AC 45,000 Btu/h and over | 13.8 SEER2 | About 14.5 SEER |
| Split heat pump | 14.3 SEER2 and 7.5 HSPF2 | About 15 SEER and 8.8 HSPF |
| Single package AC | 13.4 SEER2 | About 14 SEER |
| Single package heat pump | 13.4 SEER2 and 6.7 HSPF2 | About 14 SEER and 8 HSPF |
A lot of HVAC websites say the Florida minimum is 15 or 15.2 SEER2. That is not what the federal rule says. The legal floor for a typical home split system is 14.3 SEER2. Anything above that is a choice, not a requirement.
Why the Install Date Matters
The Southeast standard is enforced by installation date. The DOE regional enforcement page explains that the Southeast standards apply only to split system air conditioners, and distributors can face penalties for selling to contractors who install non-compliant units. If someone offers you a cheap older unit below 14.3 SEER2, it cannot legally go into a Florida home.
Is a Higher SEER2 System Worth It in Panama City?
Panama City homes run the AC most of the year, so efficiency matters more here than in most of the country. Research from UF/IFAS Florida extension found that upgrading an old, low efficiency AC to a 15 SEER system can cut cooling costs by around 40%. Most of that saving comes from leaving an old 8 or 10 SEER unit behind.
Going from the minimum to a very high rating saves less per step. Here is how to decide:
- Check your current system’s age and rating. A unit over 12 years old is likely far below today’s minimum.
- Ask for a load calculation. Correct sizing does more for comfort and humidity than a higher rating.
- Look at variable speed options. They cost more, but they run longer at low speed and pull more moisture from Florida air.
- Get the ducts checked. A high SEER2 unit on leaky ducts will never reach its rated efficiency.
- Compare total cost. Weigh the price difference against your yearly cooling bill and how long you plan to stay.

Refrigerant and Tax Credit Changes to Know
Two other changes affect new systems. First, new residential split systems now use lower impact refrigerants such as R-454B or R-32 under EPA rules. Existing R-410A systems can still be repaired and recharged.
Second, the federal energy efficiency tax credit has changed. The ENERGY STAR tax credits page shows that credits of up to $2,000 for qualifying heat pumps were available for equipment installed through December 31, 2025. Check with your tax advisor before counting on any credit for a 2026 install.
Heat Pumps and SEER2
Many Panhandle homes use a heat pump instead of a furnace. Split heat pumps must meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. If you want to compare options, see our heat pump repair services for Bay County.
Ductless Mini Splits and SEER2 in Florida
Ductless systems follow their own rating rules and often score well above central systems. They make sense for additions, garages and rooms the main system cannot reach. If that fits your home, ask about ductless mini split installation alongside your central AC quote.
How to Read an SEER2 Label and Quote
Knowing the rules for SEER2 in Florida only helps if you can check a quote. Here is what to look for:
- The SEER2 number for the matched system. The rating depends on the outdoor unit and indoor coil together, not the outdoor unit alone.
- An AHRI certificate number. This proves the exact combination was tested and certified.
- The size in tons or Btu/h. It tells you whether the 14.3 or 13.8 minimum applies.
- The refrigerant type. New systems should list R-454B or R-32.
- What is included. Permits, disposal, new line set, thermostat and warranty registration.
If a quote lists only a brand and a tonnage, ask for the SEER2 rating and AHRI number before you sign. Any honest contractor working with SEER2 in Florida will give you both.
SEER2 in Florida FAQs
What SEER2 rating do I need in Florida?
A new split central AC under 45,000 Btu/h in Florida needs at least 14.3 SEER2. Split systems of 45,000 Btu/h and larger need 13.8 SEER2. Split heat pumps need 14.3 SEER2 and 7.5 HSPF2. These federal minimums apply to systems installed since January 1, 2023.
Is SEER or SEER2 better?
SEER2 is the better measure because its test conditions are closer to real homes with real ductwork. The numbers are not directly comparable. A SEER2 rating is usually about 4% to 5% lower than the SEER rating for the same unit, so compare SEER2 to SEER2.
When did SEER2 start?
SEER2 became the official federal rating on January 1, 2023. Every central air conditioner and heat pump made after that date is rated under the new test. Older equipment still shows the original SEER rating on its label.
Can you still install R-410A systems in 2026?
Not as a new residential split system in most cases. EPA rules moved new split systems to lower impact refrigerants like R-454B and R-32. You can still repair and recharge an existing R-410A system, and R-410A remains available for service work.
