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

Significant changes are on the way for the heating and cooling industry! Cooling systems transitioning from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be implemented in 2025. These new coolants are developed to be better for the environment and satisfy updated regulations about global warming. But what does that mean for your existing HVAC system and any new services?

This transition will decrease the environmental effect of our air conditioning systems. Beginning in 2025, new AC systems will use a a different class of refrigerants that better align with climate goals. If you're contemplating getting an AC replacement soon, this is the ideal time to investigate how these new refrigerants can influence your home's comfort.

Why Are They Phasing Out R-410a for New HVAC Refrigerant?

For a long time, R-410a was the go-to refrigerant for residential air conditioners because it worked so well. But research revealed that R-410a still contributes to global warming. As a result, the Environmental Protection Agency (EPA) enacted an initiative back in 2021. The industry will steadily eliminate R-410a to make room for refrigerants that are more environmentally friendly.

The HVAC industry has implemented changes like this before. When the industry moved away from using R-22 (commonly called Freon) to R-410a, homeowners like you had to adjust. And just like then, this shift will influence how systems are constructed as well as the optimal methods for HVAC maintenance. Both residents and HVAC technicians need to prepare for these new refrigerants if they want to continue enjoying the safest, most economical cooling possible.

Which New Refrigerant Is Replacing R-410a?

The upcoming refrigerants are categorized under the new "A2L" classification and encompass the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to provide the same powerful cooling while significantly reducing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is expected to be especially efficient due to its GWP being approximately 78% less than R-410a. Although R-454B refrigerant is actually more flammable than R-410a, enhancements to system configurations and maintenance practices will ensure servicing is just as safe to perform. In addition, modern cooling systems using R-454B refrigerant are much more energy efficient, contributing to considerable savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

This change isn't only about substituting the refrigerant—it impacts the whole HVAC system because the components of R-454B refrigerant make it not suitable for use in older systems. In time, every household and business using R-410a will need to upgrade 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 substituting what's used in your current HVAC system. That's because the unique properties of R-454B refrigerant and R-32 refrigerant mean you can't use them in a system that uses R-410a.  But don't be concerned—you can keep using your current R-410a system for now. Just remember that as time passes, the expense of repairs and tune-ups will go up as R-410a becomes less available.

Anticipating the changes is the best way to manage things. If your AC system is already nearing the end of its lifespan, this is the ideal time to think about upgrading to a newer model that uses the new R-454B refrigerant. Plus, the HVAC specialists here at Taylor's Heating & Air Conditioning can support you with upgrading with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

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

But if you have difficulty reading the label or are missing your user manual, don't worry! You can always call one of the expert technicians at Taylor's Heating & Air Conditioning to assist you in determining this information. Get all the details you need by contacting us at 519-296-4437.
