Big changes are on the way for the heating and cooling business! Cooling systems moving 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 better for the environment and meet revised 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. In 2025, new AC systems will use new class of refrigerants that are more compatible with climate goals. If you're considering getting an AC replacement soon, this is the perfect time to explore how these changes can impact 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 it worked so well. But analysis showed that R-410a still negatively impacts global warming. As a result, the Environmental Protection Agency (EPA) enacted an initiative back in 2021. The industry will progressively phase out R-410a to replace it with refrigerants that are better for the environment.

The HVAC industry has implemented changes like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, residents like you had to follow suit. And in the same way, this shift will influence how systems are engineered as well as the best practices for HVAC maintenance. Both property owners and HVAC technicians should get ready for these new refrigerants if they wish to continue enjoying the most secure, most cost-effective cooling possible.

Which New Refrigerant Is Replacing R-410a?

The coming refrigerants are categorized under the new "A2L" classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They're developed to deliver the same powerful cooling while substantially decreasing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is expected to be especially efficient due to its GWP being approximately 78% less than R-410a. Although R-454B refrigerant is technically more flammable than R-410a, enhancements to system designs and maintenance practices will ensure servicing is just as safe to perform. Additionally, today's cooling systems using R-454B refrigerant are significantly more energy efficient, leading to big savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

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

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

Transitioning to the new refrigerants won't be as simple as replacing what's used in your home's 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 don't be concerned—you can keep using your current R-410a system for now. Just keep in mind that as time passes, the expense of repairs and tune-ups will increase as R-410a becomes harder to find.

Preparing in advance is the optimal way to stay on top of things. If your AC system is currently aging, this is the perfect time to contemplate investing in a newer model that uses the new R-454B refrigerant. Plus, the HVAC specialists here at Bishop’s HVAC can assist you in switching with flexible options for HVAC replacement financing.

Which Refrigerant Is in My AC System?

Unsure which refrigerant your AC system employs? In general, you can easily find this information by examining the label on your outdoor unit. This label shows the type of refrigerant, the model number and many other details 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 skilled technicians at Bishop’s HVAC to help you in determining this information. Get all the details you need by reaching out at 916-591-6889.
