Big changes are on the way for the heating and cooling industry! 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 designed to be better for the environment and comply with revised regulations about global warming. But what does that mean for your current HVAC system and future services?

This shift will decrease the environmental impact of our air conditioning systems. In 2025, new AC systems will use an alternative class of refrigerants that are more compatible with climate goals. If you're considering getting an AC replacement soon, this is the opportune time to explore how these changes 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 of its effectiveness. But analysis revealed that R-410a still affects global warming. In response, the Environmental Protection Agency (EPA) established a strategy back in 2021. The industry will gradually discontinue R-410a to make room for refrigerants that are more eco-friendly.

The HVAC industry has implemented changes like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, property owners like you had to follow suit. And similarly, this transition will impact how systems are constructed as well as the optimal methods for HVAC maintenance. Both homeowners and HVAC technicians should prepare for these new refrigerants if they want to continue enjoying the safest, most energy-efficient 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 engineered to deliver the same effective 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 about 78% lower than R-410a. While R-454B refrigerant is actually more flammable than R-410a, improvements to system designs 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, leading to big savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

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

R-410a Replacement: How Can I Prepare to Make the Shift to New HVAC Refrigerants?

Changing to the new refrigerants won't be as straightforward as substituting what's used in your home's HVAC system. That's because the distinct properties of R-454B refrigerant and R-32 refrigerant make existing R-410a systems incompatible.  But don't worry—you can still use your current R-410a system for now. Just know that as time passes, the cost of repairs and tune-ups will go up as R-410a becomes less available.

Planning ahead is the optimal way to stay on top of things. If your AC system is currently aging, this is the best time to think about switching to a newer model that uses the new R-454B refrigerant. Plus, the staff here at Appalachian Heating can help you in switching with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Not sure which refrigerant your AC system uses? In general, you can easily find this information by checking the label on your outdoor unit. This label shows the type of refrigerant, the model number and various other specifications about your cooling system.

But if you can't read the label or are missing your user manual, don't worry! You can always connect with one of the skilled technicians at Appalachian Heating to help you in determining this information. Get all the information you need by contacting us at 304-707-0600.
