Key Points
- The type of refrigerant your AC uses depends on its age: R-22 (Freon) for systems installed before 2010, R-410A (Puron) for systems installed between 2010–2024, and R-32 or R-454B for systems purchased from 2025 onward.
- R-22 (Freon) is no longer manufactured — the EPA banned its sale and production in 2020 due to its ozone-depleting effects. If your system still uses R-22, expect extremely high costs for any refrigerant-related repair.
- R-410A is being phased out — new federal regulations effective 2025 restrict its use in new equipment, though it remains available for existing systems.
- According to the U.S. Environmental Protection Agency, only EPA-certified HVAC technicians are legally permitted to purchase and handle refrigerants — homeowners cannot legally add refrigerant themselves.
- An AC low on refrigerant will struggle to cool your home and consume significantly more energy — in North Fort Myers’s humid subtropical climate, this is felt immediately.
- If your system uses R-22 or is more than 10–15 years old, a full AC replacement is often more cost-effective than continued refrigerant repairs.

The Type of Refrigerant in Home AC Units Is Changing
Because of recent federal and state regulations, the type of refrigerant that can be added to an air conditioner has changed significantly. Freon is no longer manufactured — it was replaced by a product called Puron (R-410A). However, regulations began changing again in 2025, affecting even R-410A.
Regardless of which refrigerant your system uses, maintaining the proper level is vital. Temperatures in North Fort Myers, FL, can reach the 80s and 90s during any month, and the area’s humid subtropical climate makes an underperforming AC feel even more uncomfortable. Air conditioners that are low on refrigerant will struggle to keep your home cool and burn significantly more energy in the process.
R-410A (Puron) — Currently the Most Common Refrigerant
If HVAC technicians installed your air conditioner after 2010, it likely uses R-410A, also known by the brand name Puron.
R-410A is reasonably priced for those who need to add refrigerant to an existing system. While it’s not as environmentally friendly as next-generation options, it will remain available for servicing existing equipment for years to come. That said, new federal regulations effective 2025 restrict R-410A in new equipment — so any new AC purchased going forward will use a different refrigerant.
R-22 (Freon) — No Longer Manufactured
Can you still use R-22 refrigerant? Using R-22 — also called Freon — as an air conditioning refrigerant is no longer common, and for good reason.
The EPA made it illegal to sell or manufacture new R-22 beginning in 2020 due to its damaging effect on the Earth’s ozone layer. While limited existing supplies may still be found, R-22 is extremely expensive — often making continued repair of an R-22 system financially impractical compared to a full AC replacement.
If your system still uses Freon, now is the time to start planning for an upgrade.
Next-Generation Refrigerants: R-32 and R-454B
R-32 and R-454B are the next-generation refrigerant options. They’re safer for the environment and the ozone layer, and they meet the new energy efficiency standards driving current regulatory changes.
If you purchase a new air conditioner from 2025 onward, it will most likely use one of these refrigerants. Their lower global warming potential makes them the direction the industry is heading — and they deliver the same effective cooling performance as their predecessors.
Why AC Refrigerant Requirements Keep Changing in North Fort Myers, FL
To meet evolving energy efficiency standards and environmental concerns, allowable refrigerants for air conditioners continue to change. North Fort Myers experienced significant residential growth in the 1970s, 1980s, and 1990s — meaning many homes in the area have already gone through one or more AC replacements, and some are approaching another.
The Freon used 30 years ago is no longer available. Newer formulas balance cooling performance with energy efficiency and reduced environmental impact. Staying informed about these changes helps North Fort Myers homeowners make smarter decisions when it’s time to repair or replace their system. If you’re unsure which refrigerant your current system uses, schedule an AC inspection and our technicians will identify it for you.
Why You Cannot Add Refrigerant Yourself in North Fort Myers, FL
Regulations regarding refrigerant safety prohibit homeowners from adding refrigerant to their own air conditioners. According to the EPA and state of Florida regulations, only licensed HVAC technicians can purchase and handle refrigerants.
Attempting to add refrigerant yourself could result in:
- Regulatory violations — potentially violating state, local, and federal law
- Overcharging the system — which shortens the unit’s lifespan and reduces efficiency
- Adding the wrong refrigerant type — causing further damage and additional regulatory violations
A licensed HVAC professional handles the job correctly, achieving the right charge level safely and legally.
Conclusion
What type of refrigerant your AC uses depends on when it was installed: R-22 for older systems (pre-2010), R-410A for systems installed between 2010 and 2024, and R-32 or R-454B for new systems purchased from 2025 onward. R-22 is no longer manufactured and is extremely expensive to source — if your system still uses it, replacement is likely the smarter financial choice. Only EPA-certified HVAC technicians can legally handle refrigerants in North Fort Myers, FL — attempting DIY refrigerant work risks fines, system damage, and safety hazards. Don’t ignore low refrigerant levels, even in cooler months — an undercharged system strains to cool your home and drives up energy bills year-round.
