Major changes are on the way 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 comply with updated regulations about global warming. But what does that mean for your existing HVAC system and upcoming services?

This shift will reduce the environmental impact 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 considering getting an AC replacement soon, this is the perfect time to learn more about how these updates 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 effectiveness. But studies revealed that R-410a still affects global warming. Because of this, the Environmental Protection Agency (EPA) implemented a strategy back in 2021. The industry will gradually phase out R-410a to introduce refrigerants that are more eco-friendly.

The HVAC industry has undergone changes like this before. When the industry moved away from using R-22 (commonly called Freon) to R-410a, residents like you had to follow suit. And just like then, this shift will affect how systems are engineered as well as the optimal methods for HVAC maintenance. Both homeowners and HVAC technicians must prepare for these new refrigerants if they wish to keep experiencing the most secure, most cost-effective cooling possible.

Which New Refrigerant Is Replacing R-410a?

The upcoming refrigerants are categorized under the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to deliver the same powerful cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is believed to be especially useful due to its GWP being approximately 78% less than R-410a. Although 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. Additionally, modern cooling systems using R-454B refrigerant are much more energy efficient, resulting in substantial savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

This switch isn't just 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. In time, every residence and business using R-410a will be required to transition to one of the new systems.

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

Changing to the new refrigerants will not be as easy as swapping out the new coolants with what's used in your home's HVAC system. That's because the different properties of R-454B refrigerant and R-32 refrigerant mean you can't use them in a system that uses R-410a.  But rest assured—you can still use your current R-410a system for now. Just remember that as time goes on, the expense of repairs and tune-ups will rise as R-410a becomes less available.

Preparing in advance is the best way to handle things. If your AC system is currently nearing the end of its lifespan, 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 Freed Heating & Air Conditioning can help you in switching with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Uncertain which refrigerant your AC system uses? In general, you can easily find this information by checking 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 are unable to decipher the label or don't have your user manual, remain calm! You can always call one of the expert technicians at Freed Heating & Air Conditioning to help you in determining this information. Get all the details you need by reaching out at 309-323-9584.
