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

Big changes are on the horizon 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 designed to be better for the environment and meet new regulations about global warming. But what does that mean for your present HVAC system and any new services?

This transition will minimize the environmental footprint of our air conditioning systems. Beginning in 2025, new AC systems will use a a different class of refrigerants that better align with climate goals. If you're thinking about getting an AC replacement soon, this is the ideal time to learn more about how these changes can impact your home's comfort.

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

For a long time, R-410a was the go-to refrigerant for residential air conditioners because it worked so well. But studies uncovered that R-410a still affects 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 undergone transitions like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, residents like you had to adjust. And similarly, this change will affect how systems are constructed as well as the recommended procedures for HVAC maintenance. Both homeowners and HVAC technicians need to plan for these new refrigerants if they wish to continue enjoying the safest, most energy-efficient cooling possible.

Which New 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 created to deliver the same powerful cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is believed to be particularly effective due to its GWP being around 78% lower than R-410a. Although R-454B refrigerant is technically more flammable than R-410a, improvements to system manufacturing and maintenance practices will ensure servicing is just as safe to perform. In addition, today's cooling systems using R-454B refrigerant are significantly more energy efficient, resulting in substantial savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

This transition isn't simply about substituting the refrigerant—it affects the whole HVAC system because the properties of R-454B refrigerant make it not suitable for use in older systems. Ultimately, every residence and business using R-410a will be required 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?

Switching to the new refrigerants isn't as easy as substituting what's used in your home's HVAC system. That's because the distinct 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 keep using your current R-410a system for now. Just keep in mind that as time goes on, the cost of repairs and tune-ups will go up as R-410a becomes harder to find.

Anticipating the changes is the most effective way to manage 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 HVAC specialists here at Durable Service can support you with making the transition with flexible options for HVAC replacement financing.

What Type of Cooling Refrigerant Is in My HVAC System?

Unsure which refrigerant your AC system uses? In general, you can easily learn this information by inspecting 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 call one of the expert technicians at Durable Service to help you in figuring it out. Get all the details you need by reaching out at 308-995-8177.
