Major changes are on the horizon 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 arriving in 2025. These new coolants are engineered to be more beneficial to the environment and satisfy revised regulations about global warming. But what does that mean for your current HVAC system and upcoming services?

This change will reduce the environmental impact of our air conditioning systems. Beginning in 2025, new AC systems will use an alternative class of refrigerants that more closely match with climate goals. If you're contemplating getting an AC replacement soon, this is the opportune time to investigate how these new refrigerants can affect your home's comfort.

Why Exactly Is R-410a Being Phased Out?

For a long time, R-410a was the preferred refrigerant for residential air conditioners because of its effectiveness. But analysis showed that R-410a still affects global warming. In response, the Environmental Protection Agency (EPA) enacted a plan back in 2021. The industry will gradually phase out R-410a to make room for refrigerants that are better for the environment.

The HVAC industry has undergone 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 in the same way, this shift will influence how systems are constructed as well as the recommended procedures for HVAC maintenance. Both residents and HVAC technicians should plan for these new refrigerants if they wish to continue enjoying the safest, most cost-effective cooling possible.

What Refrigerant Is Replacing R-410a?

The new batch of refrigerants are categorized under the new "A2L" classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They're engineered to deliver the same efficient 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 about 78% less than R-410a. While R-454B refrigerant is believed to be more flammable than R-410a, improvements to system designs and maintenance practices will ensure servicing is just as safe to perform. In addition, contemporary cooling systems using R-454B refrigerant are significantly more energy efficient, resulting in considerable savings on energy bills over time, especially if you maintain your system with routine HVAC maintenance.

This transition isn't just about substituting the refrigerant—it affects the whole HVAC system because the characteristics of R-454B refrigerant make it incompatible with older systems. In time, every household and business using R-410a will be required to upgrade to one of the new systems.

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

Switching to the new refrigerants won't be 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 mean you can't use them in a system that uses R-410a.  But don't be concerned—you can still use your current R-410a system for now. Just keep in mind that as time passes, the price of repairs and tune-ups will go up as R-410a becomes less available.

Preparing in advance is the most effective way to handle things. If your AC system is already nearing the end of its lifespan, this is the perfect time to consider investing in a newer model that uses the new R-454B refrigerant. Plus, the staff here at Better Air can support you with making the transition 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 learn this information by examining 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 have difficulty reading the label or are missing your user manual, don't worry! You can always connect with one of the expert technicians at Better Air to assist you in identifying the refrigerant. Get all the info you need by giving us a call at 507-663-1208.
