New HVAC Refrigerant in 2025: Big Changes Will Go into Effect for HVAC Coolants.

Big changes are on the way for the heating and cooling industry! Cooling systems transitioning from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be implemented in 2025. These new coolants are designed to be better for the environment and satisfy new regulations about global warming. But what does that mean for your current HVAC system and upcoming services?

This transition will decrease the environmental effect of our air conditioning systems. Beginning in 2025, new AC systems will utilize a a different 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 updates can influence your home's comfort.

Why Exactly Is R-410a Being Phased Out?

For years, R-410a was the standard refrigerant for residential air conditioners because of its efficiency. But research uncovered that R-410a still contributes to global warming. In response, the Environmental Protection Agency (EPA) enacted a plan back in 2021. The industry will progressively eliminate R-410a to make room for refrigerants that are more environmentally friendly.

The HVAC industry has undergone changes like this before. When the industry moved away from using R-22 (commonly called Freon) to R-410a, residents like you had to adjust. And just like then, this change will impact how systems are designed as well as the best practices for HVAC maintenance. Both residents and HVAC technicians must plan for these new refrigerants if they want to continue enjoying the most secure, most energy-efficient cooling possible.

What Refrigerant Is Replacing R-410a?

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

R-454B refrigerant is believed to be especially useful due to its GWP being around 78% lower than R-410a. Although R-454B refrigerant is believed to be more flammable than R-410a, updates to system configurations and maintenance practices will ensure servicing is just as safe to perform. In addition, modern cooling systems using R-454B refrigerant are much more energy efficient, contributing to substantial savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

This transition isn't only about replacing the refrigerant—it affects the whole HVAC system because the components of R-454B refrigerant make it incompatible with older systems. In time, every residence and business using R-410a will have to transition to one of the new systems.

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

Switching to the new refrigerants won't be as straightforward as substituting what's used in your current 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 still use your current R-410a system for now. Just remember that as time passes, the price 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 already aging, this is the best time to consider investing in a newer model that uses the new R-454B refrigerant. Plus, the team here at Service Max Heating & Air Conditioning can assist 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 uses? In general, you can easily find this information by inspecting the label on your outdoor unit. This label shows the type of refrigerant, the model number and numerous other specifications about your cooling system.

But if you can't read the label or can't find your user manual, remain calm! You can always call one of the skilled technicians at Service Max Heating & Air Conditioning to help you in determining this information. Get all the information you need by contacting us at 360-255-5857.
