New HVAC Refrigerant in 2025: Big Changes Are on the Horizon for HVAC Coolants.

Major changes are on the horizon for the heating and cooling industry! Cooling systems moving from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be arriving in 2025. These new coolants are developed to be better for the environment and meet revised regulations about global warming. But what does that mean for your present HVAC system and future services?

This shift will minimize the environmental impact of our air conditioning systems. In 2025, new AC systems will utilize a a different class of refrigerants that are more compatible with climate goals. If you're contemplating getting an AC replacement soon, this is the perfect time to explore how these updates can influence your home's comfort.

Why Is R-410a Refrigerant Being Phased Out by New Regulations?

For years, R-410a was the preferred refrigerant for residential air conditioners because it worked so well. But research showed that R-410a still contributes to global warming. As a result, the Environmental Protection Agency (EPA) implemented a plan back in 2021. The industry will progressively discontinue R-410a to replace it with refrigerants that are better for the environment.

The HVAC industry has implemented changes like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, homeowners like you had to adjust. And just like then, this transition will influence how systems are designed as well as the recommended procedures for HVAC maintenance. Both property owners and HVAC technicians must plan for these new refrigerants if they wish to keep experiencing the safest, most energy-efficient cooling possible.

New HVAC Refrigerants Replacing R-410a?

The upcoming refrigerants fall under the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to deliver the same powerful cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is anticipated to be especially useful due to its GWP being around 78% lower than R-410a. Although R-454B refrigerant is believed to be more flammable than R-410a, updates to system designs and maintenance practices will ensure servicing is just as safe to perform. In addition, contemporary cooling systems using R-454B refrigerant are significantly more energy efficient, resulting in substantial savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

This switch isn't simply about swapping out the refrigerant—it impacts the whole HVAC system because the components of R-454B refrigerant make it incompatible with older systems. Ultimately, every residence and business using R-410a will need to transition to one of the new systems.

R-410a Replacement: What Do I Need to Do to Switch to New HVAC Refrigerants?

Transitioning to the new refrigerants won't be as simple as replacing what's used in your home's HVAC system. That's because the different properties of R-454B refrigerant and R-32 refrigerant mean you can't use the new refrigerants in a system designed to use R-410a.  But rest assured—you can keep using your current R-410a system for now. Just be aware that as time goes on, the expense of repairs and tune-ups will increase as R-410a becomes less available.

Preparing in advance is the most effective way to stay on top of things. If your AC system is currently getting old, this is the perfect time to contemplate upgrading to a newer model that uses the new R-454B refrigerant. Plus, the staff here at Giordanos Heating and Air Conditioning can assist you in switching with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Uncertain which refrigerant your AC system uses? In general, you can easily find this information by examining the label on your outdoor unit. This label shows the type of refrigerant, the model number and various other particulars about your cooling system.

But if you can't read the label or can't find your user manual, don't stress! You can always call one of the skilled technicians at Giordanos Heating and Air Conditioning to help you in identifying the refrigerant. Get all the details you need by giving us a call at 203-772-8319.
