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

This transition will decrease the environmental impact of our air conditioning systems. 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 learn more about how these changes can affect your home's comfort.

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

For years, R-410a was the go-to refrigerant for residential air conditioners because it worked so well. But studies showed that R-410a still affects global warming. In response, the Environmental Protection Agency (EPA) established an initiative back in 2021. The industry will progressively phase out R-410a to make room for refrigerants that are more environmentally friendly.

The HVAC industry has implemented transitions like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, residents like you had to follow suit. And just like then, this transition will affect how systems are constructed as well as the best practices for HVAC maintenance. Both residents and HVAC technicians must plan for these new refrigerants if they wish to continue enjoying the most reliable, most cost-effective cooling possible.

New HVAC Refrigerants Replacing R-410a?

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

R-454B refrigerant is anticipated to be especially useful due to its GWP being about 78% less than R-410a. While R-454B refrigerant is technically more flammable than R-410a, updates to system designs and maintenance practices will ensure servicing is just as safe to perform. Additionally, modern cooling systems using R-454B refrigerant are considerably more energy efficient, contributing to considerable savings on energy bills over time, especially if you maintain your system with routine HVAC maintenance.

This change isn't just about swapping out the refrigerant—it affects the whole HVAC system because the characteristics of R-454B refrigerant make it not suitable for use in older systems. In time, every home and business using R-410a will need to switch to one of the new systems.

R-410a Replacement: What Do I Need to Do to Make the Shift to New HVAC Refrigerants?

Transitioning to the new refrigerants isn't as easy as replacing what's used in your home's HVAC system. That's because the unique properties of R-454B refrigerant and R-32 refrigerant make existing R-410a systems incompatible.  But don't be concerned—you can still use your current R-410a system for now. Just keep in mind that as time passes, the cost of repairs and tune-ups will increase as R-410a becomes less available.

Anticipating the changes is the optimal 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 contemplate investing in a newer model that uses the new R-454B refrigerant. Plus, the staff here at Air Temperature Control can help you in making the transition with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Unsure which refrigerant your AC system uses? In general, you can easily learn this information by inspecting the label on your outdoor unit. This label displays the type of refrigerant, the model number and numerous other details about your cooling system.

But if you have difficulty reading the label or can't find your user manual, don't stress! You can always call one of the skilled technicians at Air Temperature Control to assist you in determining this information. Get all the info you need by reaching out at 478-202-3170.
