Major changes are on the way for the heating and cooling industry! 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 revised regulations about global warming. But what does that mean for your existing HVAC system and upcoming services?

This shift will reduce the environmental effect of our air conditioning systems. Starting with 2025, new AC systems will use an alternative class of refrigerants that better align with climate goals. If you're contemplating getting an AC replacement soon, this is the ideal time to investigate how these updates can influence your home's comfort.

Why Is R-410a Refrigerant Being Phased Out by New Regulations?

For years, R-410a was the preferred refrigerant for residential air conditioners because of its effectiveness. But studies uncovered that R-410a still contributes to global warming. Because of this, the Environmental Protection Agency (EPA) established a strategy back in 2021. The industry will gradually discontinue R-410a to make room for refrigerants that are more environmentally friendly.

The HVAC industry has implemented changes like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, property owners like you had to adjust. And just like then, this transition will impact how systems are engineered as well as the best practices for HVAC maintenance. Both residents and HVAC technicians should prepare for these new refrigerants if they want to continue enjoying the most reliable, most economical cooling possible.

Which New Refrigerant Is Replacing R-410a?

The upcoming refrigerants belong to the new "A2L" classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to provide the same efficient cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is anticipated to be especially effective due to its GWP being approximately 78% lower than R-410a. Although R-454B refrigerant is actually more flammable than R-410a, updates to system configurations and maintenance practices will ensure servicing is just as safe to perform. Additionally, contemporary cooling systems using R-454B refrigerant are considerably more energy efficient, resulting in big 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 properties of R-454B refrigerant make it not suitable for use in older systems. In time, every household and business using R-410a will be required to switch to one of the new systems.

R-410a Replacement: What Do I Need to Do to Switch to New HVAC Refrigerants?

Changing to the new refrigerants will not be as easy as substituting what's used in your home's HVAC system. That's because the unique 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 worry—you can keep using your current R-410a system for now. Just be aware that as time goes on, the expense of repairs and tune-ups will increase as R-410a becomes less available.

Planning ahead is the most effective way to handle things. If your AC system is currently nearing the end of its lifespan, this is the best time to consider upgrading to a newer model that uses the new R-454B refrigerant. Plus, the team here at Thurston Heating & Air Conditioning can support you with 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 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, remain calm! You can always connect with one of the professional technicians at Thurston Heating & Air Conditioning to help you in figuring it out. Get all the info you need by reaching out at 308-624-3485.
