The Future Of AC Refrigerants
If you’re a Florida homeowner wondering what’s changing in the world of AC refrigerants, you’re not alone. As of 2025, the HVAC industry is transitioning away from older refrigerants like R-410A — commonly referred to as Freon — and moving toward a new standard: R-454B.
At Express Air Conditioning and Heating, we’re here to explain what this means for your home AC refrigerant system and how it affects maintenance, repairs and energy efficiency here in the Sunshine State.
Why The Change To R-454B?
The transition to R-454B is driven by environmental concerns. R-410A, while more efficient than its predecessor R-22, still contributes to global warming. R-454B, on the other hand, offers a significantly lower Global Warming Potential (GWP), making it a more eco-friendly choice.
As the EPA tightens regulations, manufacturers and HVAC companies alike are preparing for a full shift to this new refrigerant in newly manufactured units.
What Does This Mean For Existing AC Units?
If your system was installed before 2023, it likely uses R-410A or even R-22. While these systems can still operate, sourcing refrigerant for Freon recharge will become increasingly expensive and difficult over time.
Here in Florida, where air conditioning is essential nearly year-round, that’s a big deal. High humidity and heat put extra stress on AC systems, making AC refrigerant leaks more likely, especially in older units. If you’re experiencing issues like warm air blowing from vents, ice on your evaporator coils or hissing noises, it could signal a Freon leak or general AC refrigerant issue that needs immediate attention.
What Should Florida Homeowners Do?
Schedule Regular AC Maintenance
In coastal areas like Pensacola and the broader Gulf Coast, salty air can accelerate wear on HVAC components, increasing the risk of an AC refrigerant leak. Preventative maintenance can catch small issues before they become big, expensive problems.
Know When To Repair vs. Replace Your AC
If your unit is nearing 10–15 years old and frequently needs Freon recharges, it may be more cost-effective to upgrade to a system that uses R-454B. New systems are more efficient and environmentally friendly — and may qualify for federal tax credits or rebates.
Stay Informed About AC Refrigerant
Be proactive. Ask your technician what refrigerant your system uses and discuss your long-term options. Upgrading your AC unit isn’t just about cooling — it’s about energy savings, indoor air quality and peace of mind during those brutal Florida summers.
