New HVAC Refrigerant in 2025: Big Changes Are Coming for HVAC Coolants.

Big changes are on the way for the heating and cooling business! Cooling systems transitioning 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 friendlier to the environment and meet updated regulations about global warming. But what does that mean for your present HVAC system and any new services?

This transition will reduce the environmental effect of our air conditioning systems. In 2025, new AC systems will employ new class of refrigerants that better align with climate goals. If you're considering getting an AC replacement soon, this is the ideal time to learn more about how these new refrigerants can affect your home's comfort.

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

For years, R-410a was the standard 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 eliminate R-410a to make room for refrigerants that are better for the environment.

The HVAC industry has undergone transitions like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, homeowners like you had to adjust. And in the same way, this change will affect how systems are constructed as well as the optimal methods for HVAC maintenance. Both residents and HVAC technicians must get ready for these new refrigerants if they want to keep experiencing the most secure, most economical cooling possible.

Which New Refrigerant Is Replacing R-410a?

The new batch of refrigerants belong to the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're created to deliver the same powerful cooling while significantly reducing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is anticipated to be particularly effective due to its GWP being approximately 78% less than R-410a. While R-454B refrigerant is believed to be more flammable than R-410a, updates to system configurations and maintenance practices will ensure servicing is just as safe to perform. In addition, today's cooling systems using R-454B refrigerant are significantly more energy efficient, resulting in considerable savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

This switch isn't simply about swapping out the refrigerant—it affects the whole HVAC system because the characteristics of R-454B refrigerant make it incompatible with older systems. Ultimately, every home 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 Change to New HVAC Refrigerants?

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

Anticipating the changes is the best way to stay on top of things. If your AC system is currently nearing the end of its lifespan, this is the perfect time to think about switching to a newer model that uses the new R-454B refrigerant. Plus, the staff here at Fal-Ken Heating & Cooling Corporation can support you with switching with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?
