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

Significant changes are coming 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 designed to be more beneficial to the environment and comply with revised regulations about global warming. But what does that mean for your existing HVAC system and future services?

This shift will reduce the environmental footprint of our air conditioning systems. Beginning 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 opportune time to explore how these new refrigerants can impact your home's comfort.

Why Are They Phasing Out R-410a for New HVAC Refrigerant?

For years, R-410a was the go-to refrigerant for residential air conditioners because it worked so well. But research revealed that R-410a still negatively impacts global warming. Because of this, the Environmental Protection Agency (EPA) enacted an initiative back in 2021. The industry will progressively eliminate R-410a to replace it with refrigerants that are more environmentally friendly.

The HVAC industry has undergone shifts like this before. When the industry moved away from using R-22 (commonly called Freon) to R-410a, homeowners like you had to follow suit. And just like then, this change will impact how systems are engineered as well as the recommended procedures for HVAC maintenance. Both residents and HVAC technicians must get ready for these new refrigerants if they want to keep experiencing the safest, most energy-efficient cooling possible.

What Refrigerant Is Replacing R-410a?

The coming refrigerants fall under the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to offer the same efficient cooling while substantially decreasing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is anticipated 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, enhancements to system designs and maintenance practices will ensure servicing is just as safe to perform. In addition, contemporary cooling systems using R-454B refrigerant are significantly more energy efficient, resulting in substantial savings on energy bills over time, especially if you maintain your system with routine HVAC maintenance.

This transition isn't just about swapping out the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it incompatible with older systems. Ultimately, every household and business using R-410a will have 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 won't be as straightforward as swapping out the new coolants with what's used in your current HVAC system. That's because the distinct properties of R-454B refrigerant and R-32 refrigerant make existing R-410a systems incompatible.  But don't be concerned—you can still use your current R-410a system for now. Just keep in mind that as time goes on, the cost of repairs and tune-ups will rise as R-410a becomes less available.

Preparing in advance is the best way to handle things. If your AC system is already getting old, this is the ideal time to contemplate upgrading to a newer model that uses the new R-454B refrigerant. Plus, the team here at I-Deal HVAC can support you with upgrading with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Unsure which refrigerant your AC system employs? In general, you can easily find this information by checking the label on your outdoor unit. This label displays the type of refrigerant, the model number and various other details about your cooling system.

But if you are unable to decipher the label or can't find your user manual, don't worry! You can always call one of the professional technicians at I-Deal HVAC to help you in determining this information. Get all the information you need by giving us a call at 505-317-9598.
