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

Significant changes are on the horizon 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 better for the environment and satisfy new regulations about global warming. But what does that mean for your current HVAC system and any new services?

This change will reduce the environmental effect of our air conditioning systems. Beginning in 2025, new AC systems will employ a a different class of refrigerants that more closely match with climate goals. If you're considering getting an AC replacement soon, this is the perfect time to learn more about how these changes can impact your home's comfort.

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

For years, R-410a was the standard refrigerant for residential air conditioners because it worked so well. But analysis uncovered that R-410a still affects global warming. Because of this, the Environmental Protection Agency (EPA) implemented a strategy back in 2021. The industry will steadily eliminate R-410a to make room for refrigerants that are more eco-friendly.

The HVAC industry has undergone transitions like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, residents like you had to follow suit. And just like then, this shift will influence how systems are designed as well as the recommended procedures for HVAC maintenance. Both homeowners and HVAC technicians need to get ready for these new refrigerants if they want to keep experiencing the safest, most economical cooling possible.

What Refrigerant Is Replacing R-410a?

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

R-454B refrigerant is believed to be especially effective due to its GWP being around 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. In addition, modern cooling systems using R-454B refrigerant are much more energy efficient, contributing to big savings on energy bills over time, especially if you maintain your system with routine HVAC maintenance.

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

R-410a Replacement: How Can I Prepare to Change to New HVAC Refrigerants?

Transitioning to the new refrigerants will not 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 make existing R-410a systems incompatible.  But rest assured—you can continue to use your current R-410a system for now. Just remember that as time goes on, the cost of repairs and tune-ups will go up as R-410a becomes scarcer.

Anticipating the changes is the optimal way to stay on top of things. If your AC system is currently aging, this is the perfect time to consider upgrading to a newer model that uses the new R-454B refrigerant. Plus, the team here at Fletcher Plumbing, Heating & AC can support you with making the transition with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

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

But if you are unable to decipher the label or don't have your user manual, don't stress! You can always connect with one of the expert technicians at Fletcher Plumbing, Heating & AC to help you in figuring it out. Get all the info you need by reaching out at 302-653-0503.
