New HVAC Refrigerant in 2025: Major Changes Are Coming for HVAC Coolants.

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 implemented in 2025. These new coolants are engineered to be friendlier to the environment and satisfy new regulations about global warming. But what does that mean for your existing HVAC system and future services?

This change will decrease the environmental effect of our air conditioning systems. Beginning in 2025, new AC systems will utilize an alternative class of refrigerants that more closely match with climate goals. If you're considering getting an AC replacement soon, this is the opportune time to explore 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 efficiency. But analysis revealed that R-410a still contributes to global warming. As a result, the Environmental Protection Agency (EPA) enacted a strategy back in 2021. The industry will progressively phase out R-410a to introduce refrigerants that are more environmentally friendly.

The HVAC industry has made shifts 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 in the same way, this change will influence how systems are designed as well as the best practices for HVAC maintenance. Both residents and HVAC technicians need to plan for these new refrigerants if they wish to continue enjoying the most reliable, most economical cooling possible.

Which New Refrigerant Is Replacing R-410a?

The new batch of refrigerants are categorized under the new "A2L" classification and encompass the newest R-454B refrigerant and R-32 refrigerant coolants. They're created to deliver the same efficient cooling while substantially decreasing 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% less than R-410a. Although R-454B refrigerant is actually more flammable than R-410a, updates to system designs and maintenance practices will ensure servicing is just as safe to perform. Additionally, contemporary cooling systems using R-454B refrigerant are significantly more energy efficient, contributing to considerable savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

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

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

Transitioning to the new refrigerants will not 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 continue to use your current R-410a system for now. Just remember that as time passes, the price of repairs and tune-ups will rise as R-410a becomes harder to find.

Anticipating the changes is the most effective way to stay on top of things. If your AC system is currently nearing the end of its lifespan, this is the perfect time to consider switching to a newer model that uses the new R-454B refrigerant. Plus, the HVAC specialists here at Evenaire Heating & Air Conditioning can help you in switching with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?
