Major changes are on the horizon for the heating and cooling business! Cooling systems moving from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be arriving in 2025. These new coolants are designed to be more beneficial to the environment and comply with new regulations about global warming. But what does that mean for your existing HVAC system and any new services?

This shift will decrease the environmental impact of our air conditioning systems. Starting with 2025, new AC systems will use new class of refrigerants that are more compatible with climate goals. If you're contemplating getting an AC replacement soon, this is the perfect time to explore how these new refrigerants can impact your home's comfort.

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

For years, R-410a was the preferred refrigerant for residential air conditioners because of its effectiveness. But analysis showed that R-410a still contributes to global warming. In response, the Environmental Protection Agency (EPA) established a strategy back in 2021. The industry will progressively discontinue R-410a to replace it with refrigerants that are better for the environment.

The HVAC industry has made shifts like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, homeowners like you had to adjust. And in the same way, this transition will affect how systems are designed as well as the recommended procedures for HVAC maintenance. Both residents and HVAC technicians must get ready for these new refrigerants if they want to continue enjoying the most reliable, most cost-effective cooling possible.

New HVAC Refrigerants Replacing R-410a?

The new batch of refrigerants fall under the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to provide the same powerful cooling while significantly reducing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is believed to be especially effective due to its GWP being about 78% lower 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. Additionally, modern cooling systems using R-454B refrigerant are considerably more energy efficient, contributing to considerable savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

This change isn't just about swapping out the refrigerant—it affects the whole HVAC system because the characteristics of R-454B refrigerant make it not suitable for use in older systems. Ultimately, every household and business using R-410a will need to upgrade to one of the new systems.

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

Transitioning to the new refrigerants won't be as simple as substituting 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 the new refrigerants in a system designed to use R-410a.  But rest assured—you can continue to use your current R-410a system for now. Just know that as time progresses, the price of repairs and tune-ups will rise as R-410a becomes scarcer.

Planning ahead is the optimal way to stay on top of things. If your AC system is currently getting old, this is the best time to contemplate upgrading to a newer model that uses the new R-454B refrigerant. Plus, the team here at Siloam Springs Heating & AC 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 employs? In general, you can easily learn this information by examining the label on your outdoor unit. This label shows the type of refrigerant, the model number and many other particulars about your cooling system.

But if you can't read the label or don't have your user manual, don't worry! You can always call one of the skilled technicians at Siloam Springs Heating & AC to assist you in determining this information. Get all the info you need by giving us a call at 479-308-8176.
