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

Significant changes are on the horizon for the heating and cooling business! Cooling systems moving 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 more beneficial to the environment and meet revised regulations about global warming. But what does that mean for your existing HVAC system and future services?

This transition will minimize the environmental footprint of our air conditioning systems. In 2025, new AC systems will use new class of refrigerants that better align with climate goals. If you’re thinking about getting an AC replacement soon, this is the perfect time to investigate how these changes can affect your home’s comfort.

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

For a long time, R-410a was the preferred refrigerant for residential air conditioners because of its efficiency. But research revealed that R-410a still negatively impacts global warming. As a result, the Environmental Protection Agency (EPA) implemented a plan back in 2021. The industry will gradually discontinue R-410a to introduce refrigerants that are more environmentally friendly.

The HVAC industry has implemented transitions like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, residents like you had to adapt. And similarly, this shift will affect how systems are constructed as well as the optimal methods for HVAC maintenance. Both residents and HVAC technicians need to get ready for these new refrigerants if they want to keep experiencing the most secure, most energy-efficient cooling possible.

New HVAC Refrigerants Replacing R-410a?

The upcoming refrigerants are categorized under the new “A2L” classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They’re developed to offer the same efficient cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is anticipated to be particularly useful due to its GWP being approximately 78% less than R-410a. While R-454B refrigerant is technically more flammable than R-410a, enhancements to system manufacturing and maintenance practices will ensure servicing is just as safe to perform. Additionally, today’s cooling systems using R-454B refrigerant are considerably more energy efficient, resulting in considerable savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

This switch isn’t only about replacing the refrigerant—it impacts the whole HVAC system because the properties of R-454B refrigerant make it incompatible with older systems. In time, 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 Change to New HVAC Refrigerants?

Changing to the new refrigerants won’t be as straightforward as replacing 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 the new refrigerants in a system designed to use R-410a.  But don’t worry—you can continue to use your current R-410a system for now. Just keep in mind that as time progresses, the price of repairs and tune-ups will go up as R-410a becomes harder to find.

Anticipating the changes is the best way to manage things. If your AC system is currently aging, 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 Cytech Heating & Cooling L.C. can help you in upgrading with flexible options for HVAC replacement financing.

What Type of Cooling Refrigerant Is in My HVAC System?

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

But if you can’t read the label or don’t have your user manual, don’t stress! You can always connect with one of the skilled technicians at Cytech Heating & Cooling L.C. to help you in identifying the refrigerant. Get all the information you need by contacting us at 956-553-3265.
