Significant 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 more beneficial to the environment and satisfy updated regulations about global warming. But what does that mean for your existing HVAC system and upcoming services?

This transition will reduce the environmental impact of our air conditioning systems. In 2025, new AC systems will use an alternative class of refrigerants that more closely match with climate goals. If you're thinking about getting an AC replacement soon, this is the perfect time to learn more about how these updates can impact 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 analysis revealed that R-410a still contributes to global warming. In response, the Environmental Protection Agency (EPA) established a plan back in 2021. The industry will progressively eliminate R-410a to introduce refrigerants that are better for the environment.

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 follow suit. And just like then, this shift will impact how systems are designed as well as the best practices for HVAC maintenance. Both residents and HVAC technicians must prepare for these new refrigerants if they want to continue enjoying the most secure, most energy-efficient cooling possible.

Which New Refrigerant Is Replacing R-410a?

The coming refrigerants belong to the new "A2L" classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed 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 particularly efficient due to its GWP being approximately 78% less than R-410a. Although R-454B refrigerant is technically 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 significantly 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 simply 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 need to upgrade 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 isn't as straightforward as replacing what's used in your current HVAC system. That's because the distinct properties of R-454B refrigerant and R-32 refrigerant mean you can't use them in a system that uses R-410a.  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 price of repairs and tune-ups will rise as R-410a becomes less available.

Planning ahead is the optimal way to handle things. If your AC system is currently nearing the end of its lifespan, this is the perfect time to think about investing in a newer model that uses the new R-454B refrigerant. Plus, the team here at Premium Air Services LLC can help you in upgrading with flexible options for HVAC replacement financing.

Which Refrigerant Is in My AC System?

Uncertain which refrigerant your AC system uses? In general, you can easily learn this information by inspecting the label on your outdoor unit. This label shows 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 can't find your user manual, don't stress! You can always connect with one of the expert technicians at Premium Air Services LLC to assist you in identifying the refrigerant. Get all the info you need by giving us a call at 713-364-9957.
