Florida AC Permit and SEER2 Requirements
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 Nifty Air Conditioning is a family-operated South Florida HVAC contractor founded in 1997 with offices in Margate and Palmetto Bay, Florida. We pull permits and handle code compliance under Florida HVAC license CAC1824313 across Miami-Dade, Broward, and Palm Beach counties.

What does the SEER2 standard require in Florida?
Florida is part of the federal Southeast region, so every new split-system central AC under 45,000 BTU must meet 14.3 SEER2, with larger units required to hit 13.8 SEER2 (International Code Council summary of DOE 2023 rule, 2022). The 14.3 SEER2 floor is the federal minimum for the Southeast region under the U.S. Department of Energy’s 2023 standard, which is roughly equivalent to 15 SEER under the prior test method. Heat pumps installed anywhere in the country must meet 14.3 SEER2 and 7.5 HSPF2 (the national heat-pump minimum). Both standards are non-negotiable, and any system installed below the threshold can’t be permitted in Florida.
The DOE 2023 efficiency standard for residential central air conditioners and heat pumps took effect on January 1, 2023. The SEER2 rating is the post-2023 efficiency metric that replaced the older SEER number. It measures cooling output in BTUs divided by electricity input in watt-hours under updated test conditions that better reflect real-world operation, with higher external static pressure built into the test. That extra pressure accounts for the resistance ducts and registers add in a real home.
The key practical change is that SEER2 numbers are roughly 4 to 6 percent lower than the equivalent SEER number on the same equipment. A unit that was rated 16 SEER under the old test typically rates around 15.2 SEER2 under the new one. The rating method is more conservative, but the federal floor is set at 14.3 SEER2 for our region, so every new install today is benchmarked against that number.
ENERGY STAR thresholds matter for tax credits and rebates
ENERGY STAR-rated central AC units sit above the federal floor and qualify for a higher-efficiency tier required for the IRS Section 25C tax credit. A system that hits the federal 14.3 SEER2 floor gets permitted in Florida. A system that meets the ENERGY STAR threshold in effect for the install year unlocks the federal tax credit and the FPL rebate.
The IRS Section 25C Energy Efficient Home Improvement Credit covers 30 percent of qualifying equipment cost, capped at $600 per year for central AC and $2,000 per year for a qualifying heat pump, with a combined annual cap of $3,200 across all qualifying improvements (IRS, 2025). The two caps are separate. A homeowner doing a like-for-like central AC replacement claims under the $600 line. A homeowner installing a qualifying heat pump claims under the $2,000 line. To qualify, the equipment has to meet the ENERGY STAR efficiency tier in effect when the system is installed.
Florida Power and Light runs a Residential AC Rebate program under its Energy Saving Programs that pays an instant rebate per qualifying high-efficiency AC install, with rebate amounts and qualifying tiers updated annually. Rebate processing typically takes six to eight weeks after the install paperwork is submitted, and FPL publishes the current program at FPL.com under Energy Saving Programs.
What permit do I need for an AC install in Florida?
Permits are required for every AC replacement in Miami-Dade, Broward, and Palm Beach counties. The permit application names the licensed contractor, the equipment manufacturer, the model number, and the AHRI Directory match number, which the homeowner uses for IRS Section 25C tax credit eligibility and FPL rebate processing. The permit office runs a final inspection after the install is complete, and the permit closes when the inspector signs off.
Air Nifty pulls the county permit as the licensed contractor under Florida HVAC license CAC1824313, a Class A Air Conditioning Contractor license verified through the Florida DBPR Construction Industry Licensing Board public registry. The homeowner doesn’t interact with the permit office at any point, and the homeowner doesn’t need to be home for the inspection portion.
The permit application names the contractor as the responsible party. If the contractor isn’t licensed, the permit office won’t accept the application. That’s the gate that keeps unlicensed installs out of the residential market in Florida. Asking for a contractor’s license number on the quote is a fair question, and the public DBPR registry lets any homeowner verify the answer in under a minute.
Permit fees vary by county and by the scope of work. The Air Nifty quote includes the permit fee as a line item, which means no surprise add-on after the install is signed.
Hurricane mounting and Florida Building Code
Florida Building Code amendments in Miami-Dade and Broward counties require outdoor HVAC units to be mounted to High-Velocity Hurricane Zone provisions, including hurricane straps and properly anchored pads. Palm Beach County uses the standard Florida Building Code wind-load provisions. The mounting requirements aren’t optional, and the inspector verifies the mounting during the post-install inspection.
The HVHZ provisions in Miami-Dade and Broward raise the wind-load standard for outdoor unit mounts. The specs require hurricane straps, properly anchored pads, and in some configurations wind-rated stand-offs. Palm Beach uses the standard Florida Building Code provisions, which are still strict relative to most non-hurricane states. Both standards are enforced through the permit and inspection process.
A unit mounted incorrectly may pass initial install but fail the inspection. A failed inspection delays the permit close, which can affect insurance coverage if the system is damaged before the permit is closed. Air Nifty installs every outdoor unit to the applicable county standard and documents the mounting on the permit application so the inspection runs cleanly.
Refrigerant rules under EPA Section 608 and the AIM Act
Refrigerant work, including leak detection, recharging, and recovery, requires EPA Section 608 certified technicians under the Clean Air Act. The program has four certification types: Type I for small appliances, Type II for high-pressure systems, Type III for low-pressure systems, and Universal. Air Nifty installation crews hold the relevant certifications, and the permit application is signed by the licensed contractor as a separate compliance attestation.
R-22 refrigerant has been out of new production and import since January 1, 2020 under the EPA Clean Air Act Section 608 phaseout. Recovered and recycled R-22 stocks remain legal for servicing existing systems. Any new AC installed today uses R-410A or one of the next-generation low-GWP refrigerants. Older systems still running on R-22 can be serviced with recovered stock, but the supply is limited and prices have risen since the 2020 phaseout.
Under the EPA Technology Transitions rule, new residential central ACs and heat pumps manufactured on or after January 1, 2025 must use refrigerants with a global warming potential of 700 or less, effectively phasing out R-410A in new equipment (US EPA, 2023). R-454B and R-32 systems are coming to market on a manufacturer-by-manufacturer schedule. R-410A equipment that’s already installed is fine. Existing R-410A systems can continue to operate and be serviced with reclaimed and recycled stock for their full design life.
How Air Nifty handles the permit and inspection
Air Nifty installs three manufacturer brands at named program tiers: Lennox Authorized Dealer, Rheem Preferred Dealer, and Daikin Comfort Pro. All three brand lineups include systems that meet or exceed both the federal SEER2 floor and the ENERGY STAR tier required for IRS Section 25C credit eligibility.
The install workflow is consistent across all three counties. The licensed technician runs a Manual J load calculation during the in-home assessment, the homeowner reviews equipment options at the quote stage, the county permit is pulled before install day, the install is completed in a single day for like-for-like replacements, and the post-install inspection closes the permit. Throughout, the AHRI Directory match number for the installed equipment is recorded on the permit application and provided to the homeowner for tax credit and FPL rebate filings.
If the homeowner is claiming the IRS Section 25C credit, the AHRI Directory match number goes on the IRS energy credit form with the federal return. If the homeowner is filing for an FPL rebate, the same AHRI Directory match number plus the install date documentation goes on the FPL rebate application. Air Nifty doesn’t process the credit or rebate applications on the homeowner’s behalf, but we provide the documentation the homeowner needs.

FAQs
Does my new AC need to meet SEER2 in Florida?
Yes. Florida sits in the federal Southeast region, so every new split-system central AC under 45,000 BTU must meet 14.3 SEER2 (with 13.8 SEER2 for larger units). Heat pumps must hit 14.3 SEER2 and 7.5 HSPF2 nationally. The federal floor is the same across Florida, and any installed system below the floor cannot be permitted.
Why SEER2 replaced SEER
SEER2 is the post-2023 efficiency metric that replaced the older SEER number. It measures cooling output divided by electricity input under updated test conditions, with higher external static pressure built in to better reflect real-world duct resistance. SEER2 numbers are roughly 4 to 6 percent lower than the equivalent SEER number on the same equipment, but the rating method is more accurate.
Who pulls the permit for an AC install?
Air Nifty pulls the permit as the licensed contractor under Florida HVAC license CAC1824313 and schedules the final county inspection. The homeowner doesn’t interact with the permit office. The permit application names Air Nifty as the responsible contractor, lists the equipment manufacturer and AHRI Directory match number, and references the install location.
Do I qualify for an IRS tax credit on a new AC install?
If your central AC meets the ENERGY STAR efficiency tier in effect when you install, you may qualify for the IRS Section 25C credit. The credit covers 30 percent of qualifying equipment cost up to $600 per year for central AC. A qualifying heat pump claims under a separate $2,000 per year cap. The credit is nonrefundable, so it’s limited by your federal income tax liability for the year. Always confirm with your tax preparer.
What about FPL rebates?
Florida Power and Light runs a Residential AC Rebate program for qualifying high-efficiency AC installs. Rebate amounts and qualifying tiers update annually. FPL publishes the current program at FPL.com under Energy Saving Programs. Rebate processing typically takes six to eight weeks after install paperwork submission.
What refrigerant does my new system use?
R-410A is still common in residential equipment, and many new installs use it. The transition to R-454B and R-32 is underway under EPA’s Technology Transitions rule, which caps refrigerants on new central ACs and heat pumps manufactured from January 1, 2025 at a global warming potential of 700 or less. Existing R-410A systems can continue to operate and be serviced for their full design life through reclaim and recycling programs.
Hurricane code mounting and Air Nifty
Yes. Air Nifty installs every outdoor unit to the applicable Florida Building Code wind-load standard, including HVHZ mounting in Miami-Dade and Broward, plus standard FBC mounting in Palm Beach. The mounting is documented on the permit application and verified during the post-install inspection.
