📌 Key Points
- Not a ban: R-410A remains legal to use, service, and repair in existing systems with no end date. The rules target new equipment manufacturing.
- What changed in 2025: New residential systems must use refrigerants under a 700 GWP limit, so manufacturers shifted production to R-32 and R-454B.
- What changed in 2026: EPA removed the installation deadline for R-410A systems whose specified components were all made or imported before 2025, so remaining inventory can still be installed while supplies last.
- Cost outlook: Servicing R-410A stays legal indefinitely, but prices are expected to climb as the overall U.S. HFC supply cap falls to 15 percent of baseline in 2036.
- Florida timing: If your system is over 10 years old, weigh any major repair against replacement before peak cooling season.
The Florida heat is unforgiving, and for homeowners in the Sunshine State, the air conditioner isn’t a luxury; it’s essential. If you’ve been shopping for a replacement AC or scheduling repairs lately, you have likely heard rumors of a major shake-up: the “ban” on R-410A (Puron).
The rumors are true, but the reality is more nuanced than a simple ban. In 2026, the HVAC landscape is undergoing its biggest shift in decades due to the AIM Act, a 2020 federal law that EPA implements.
This article explains what is actually happening, what 2026 means for Florida homeowners, and how the transition affects air conditioner repairs and replacements in Central Florida.
What R-410A Is and Why It’s Being Phased Out
R-410A (often called Puron) was the “green” alternative to the ozone-depleting R-22 (Freon) and replaced it in 2010. While R-410A does not damage the ozone layer, it has a high Global Warming Potential (GWP).
The federal phase-down is driven by environmental policy aimed at reducing the climate impact of high-GWP refrigerants. The mandated transition is administered in the U.S. by the United States Environmental Protection Agency (EPA) under the American Innovation and Manufacturing (AIM) Act.
In simple terms, R-410A works well, but it contributes more to climate warming than newer refrigerants, so the federal government is gradually reducing its use in new equipment.
This is not a sudden change. It is a multi-year transition already underway across the HVAC industry. Since January 1, 2025, new residential air conditioning equipment must use refrigerants with a GWP below 700. R-410A, with a GWP of 2,088, does not qualify, which effectively eliminates it from new product lines.
Phase Out Timeline: 2025 Through 2036
| Date | Milestone | What It Means for You |
|---|---|---|
| Jan 1, 2025 | New equipment manufacturing cutoff | Manufacturers (Carrier, Trane, Lennox, Daikin, and others) stopped building residential systems that use refrigerants above the 700 GWP limit. R-410A, at a GWP of 2,088, did not make the cut, so production shifted to R-32 and R-454B systems. |
| 2026 | EPA removes the installation deadline | EPA’s final rule (91 FR 31284, effective July 27, 2026) removed the installation deadline for residential and light commercial systems whose specified components were all made or imported before January 1, 2025. Remaining R-410A inventory can now be installed until supply runs out, which has opened a limited buying window. |
| Jan 1, 2028 | Sell-through ends for packaged units | Self-contained products such as packaged units, window air conditioners, and PTACs received a three-year sell-through. Units built before 2025 can be sold and distributed until this date. After it, remaining R-410A products cannot be sold or distributed. |
| 2036 | HFC phasedown reaches its final step | The AIM Act schedule bottoms out at an 85 percent cut in U.S. HFC production and imports from baseline. R-410A stays legal for servicing existing systems, but supply increasingly comes from reclaimed refrigerant at higher prices. |
A2L Refrigerants Are the New Standard
R-410A is being replaced by a new class of A2L refrigerants, specifically R-454B and R-32. These alternatives are classified as “mildly flammable” but have a significantly lower environmental impact.
The Two Primary Replacements
- R-454B (Puron Advance™): This is a blend of R-32 and R-1234yf. It is the preferred replacement for many major manufacturers (like Carrier, Trane, Bryant) because it has the lowest GWP among the main contenders (around 466) and offers performance very similar to R-410A.
- R-32: It is a pure, single-component refrigerant that is highly efficient, easy to recycle, and already popular worldwide. It has been adopted by brands like Daikin and Goodman. It has a GWP of about 675 and provides better energy efficiency and cooling capacity than R-410A, though it operates at higher discharge temperatures.
Are they safe? You may hear these called “mildly flammable.” While technically true, A2L refrigerants are designed to be significantly harder to ignite than traditional flammable gases and require specific conditions and concentrations to burn. New HVAC systems are engineered to meet updated safety and installation standards for these refrigerants, and depending on the equipment type and application, most new systems also include leak detection or mitigation features.
What This Means for Central Florida Homeowners
- New refrigerants require new equipment. The next generation of refrigerants cannot be installed in existing R-410A systems. Replacement systems must be specifically designed and certified for these newer refrigerants.
- Upfront replacement costs may be slightly higher at first. New equipment platforms include updated components and safety designs, which can increase initial system costs. However, improved energy efficiency and the rising long-term cost of repairing older R-410A systems can help offset that higher upfront investment.
- R-410A repairs are still allowed, but will likely become more expensive. Existing systems can continue to be serviced, and under the EPA’s rules you can even replace an individual failed component, such as an indoor coil or condensing unit, with a matching R-410A part. Replacing both counts as a new system. A new system must use a refrigerant below 700 GWP unless every specified component was made or imported before January 1, 2025. Expect refrigerant pricing and availability to become less predictable as supply is gradually reduced.
- A limited R-410A buying window is open while inventory lasts. With the installation deadline gone, systems whose specified components were all built before 2025 can still be installed legally with no cutoff date. A discounted R-410A system can make short-term sense for some budgets, but weigh the lower sticker price against rising refrigerant service costs over a 15-year equipment life.
- Your replacement options will keep narrowing. Expect new model families, new refrigerant names, and steadily fewer R-410A systems on the market as the remaining pre-2025 inventory sells through.
- Repair vs. replacement decisions are more critical with R-410A systems. For older systems, major repairs such as compressor failures, refrigerant leaks, or coil replacements require careful evaluation. As R-410A supplies and equipment decline, repairing aging systems may provide less long-term value than replacing them with newer systems.
- Planning ahead is especially important in Central Florida. Because air conditioning systems run longer and harder in our climate, proactive replacement planning can help avoid limited equipment choices and higher costs during peak cooling season.
Your Next Step
If your HVAC system is over 10 years old, have a trusted AC technician perform a health check ahead of the next cooling season. Ask them specifically: “If this compressor dies next year, will I be able to get parts and refrigerant at a reasonable price, or should I look at the new A2L units now?”
Florida Homeowner Refrigerant Transition FAQs
Is R-410A banned in Florida?
No. Florida does not have a state law banning R-410A installations. The change is driven by federal equipment manufacturing requirements and market availability, not a Florida installation ban.
Is R-410A (Puron) going to be banned completely?
No. The EPA is banning the production of new R-410A equipment, but the production of the refrigerant itself is being phased down gradually, not banned overnight. You will still be able to buy R-410A for servicing existing units, but it will eventually come primarily from reclaimed (recycled) sources, which will likely drive up the price.
Do I have to replace my current R-410A system because of the new rules?
No. The new regulations only apply to the manufacturing and installation of new systems. If your current R-410A system is working well, you can keep using it. However, be aware that as supply tightens, repairs involving refrigerant refills will likely become more expensive over the next few years.
Will I still be able to get R-410A for repairs?
Yes. R-410A can still be used to service existing systems, but its price and availability may become less predictable, with supply likely scarcer over time.
How long will R-410A be available?
R-410A will continue to be available for servicing existing systems for the foreseeable future, but it will gradually become more limited and more expensive.
The current regulations focus on reducing the future production and use of high-GWP refrigerants, not banning their use in existing equipment. As a result:
- R-410A will still be sold for repairs.
- Long-term supply will shrink.
- Pricing will likely increase, especially during peak cooling season.
In practical terms, homeowners should expect R-410A to remain available for years, but at a higher and more volatile cost than in the past.
Where can I buy R-410A?
Homeowners cannot legally buy R-410A refrigerant directly. Under the EPA’s Section 608 of the Clean Air Act, you must hold a valid EPA Technician Certification to purchase R-410A.
R-410A is usually sold through:
- HVAC supply wholesalers
- Licensed HVAC contractors
- Refrigerant distributors
Because of regulatory requirements:
- Sellers must track refrigerant usage
- Buyers must be licensed technicians
- Retail purchase by homeowners is restricted
If you need R-410A for maintenance or repair, the best way to get it is through a licensed HVAC contractor. They have access to proper refrigerant supplies and the equipment needed to safely recover, recycle, and recharge systems according to federal and local codes.
How much does R-410A cost?
The price of R-410A will vary based on factors such as market supply and demand, location, and volume needed.
As of early 2026, homeowners in Central Florida typically pay between $50 and $100 per pound for R-410A.
- Standard Service: $50 to $80 per pound.
- Emergency/Peak Season: $90 to $125+ per pound.
If your system is low on refrigerant, you will likely pay a Service Call Fee plus the cost of the refrigerant.
- Minor “Top Off” (1 to 3 lbs): $250 to $450 total.
- Major Recharge (4 to 8 lbs): $500 to $900+ total.

Can I use the new refrigerants (R-454B or R-32) in my old AC unit?
No. The new A2L refrigerants operate at different pressures and require specific safety components, such as spark-free electrical parts and leak sensors. Putting A2L refrigerant into an older R-410A system is unsafe, not permitted in equipment not designed for it, and likely to damage the system.
Will new HVAC systems cost more because of the refrigerant change?
Likely, yes. The new equipment requires advanced sensors, updated control boards, and potentially different compressors to handle A2L refrigerants safely. While the upfront cost may be higher, these newer systems often provide better energy efficiency, which can help lower your monthly Duke Energy, FPL or OUC bill.
Will higher efficiency in new systems help offset the higher upfront price?
Often, yes. Newer systems are typically more efficient, and in Central Florida’s high-usage climate, energy savings, combined with avoiding future R-410A repair costs, can help offset part of the higher initial investment over time.
Why is planning ahead more important in Central Florida?
Because air conditioning systems run longer and harder in Florida’s heat and humidity, failures often happen during peak season. Planning ahead helps homeowners avoid limited equipment availability, longer wait times, and higher replacement costs, especially during the refrigerant transition.
How does this change affect the repair-versus-replace decision?
For older R-410A systems, large repairs such as compressor failures or major refrigerant leaks should be evaluated more carefully. Rising refrigerant costs and changing equipment platforms can make replacement a better long-term value in some cases.
