New HVAC Refrigerant in 2025: Major Changes Will Go into Effect for HVAC Coolants.

Big changes are coming for the heating and cooling business! Cooling systems shifting 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 present HVAC system and any new services?

This shift will minimize the environmental footprint of our air conditioning systems. Beginning in 2025, new AC systems will utilize new 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 explore how these new refrigerants can impact your home's comfort.

Why Exactly Is R-410a Being Phased Out?

For a long time, R-410a was the standard refrigerant for residential air conditioners because it worked so well. But research showed that R-410a still affects global warming. As a result, the Environmental Protection Agency (EPA) enacted an initiative back in 2021. The industry will progressively eliminate R-410a to replace it with refrigerants that are more eco-friendly.

The HVAC industry has made transitions like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, homeowners like you had to follow suit. And just like then, this shift will impact how systems are engineered as well as the optimal methods for HVAC maintenance. Both homeowners and HVAC technicians need to prepare for these new refrigerants if they wish to keep experiencing 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 provide the same effective cooling while substantially decreasing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is believed to be especially efficient due to its GWP being around 78% lower than R-410a. Although R-454B refrigerant is believed to be more flammable than R-410a, updates to system manufacturing 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, leading to considerable savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

This switch isn't only about swapping out the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it not suitable for use in older systems. Ultimately, every residence and business using R-410a will be required to switch to one of the new systems.

R-410a Replacement: What Should I Consider in Order to Transition to New HVAC Refrigerants?

Changing to the new refrigerants isn't as easy as replacing what's used in your current 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 be concerned—you can continue to use your current R-410a system for now. Just be aware that as time goes on, the expense of repairs and tune-ups will rise as R-410a becomes harder to find.

Preparing in advance is the most effective way to stay on top of things. If your AC system is currently aging, this is the perfect time to think about investing in a newer model that uses the new R-454B refrigerant. Plus, the staff here at Dave's Diversified Services can support you with making the transition with flexible options for HVAC replacement financing.

Which Refrigerant Is in My AC System?

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

But if you can't read the label or are missing your user manual, don't stress! You can always call one of the skilled technicians at Dave's Diversified Services to help you in figuring it out. Get all the information you need by reaching out at 540-636-3396.
