New HVAC Refrigerant in 2025: Big Changes Are on the Horizon for HVAC Coolants.

Major changes are on the way 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 arriving in 2025. These new coolants are developed to be better for the environment and satisfy revised regulations about global warming. But what does that mean for your present HVAC system and upcoming services?

This shift will reduce the environmental impact of our air conditioning systems. Starting with 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 ideal time to learn more about how these changes can impact your home's comfort.

Why Exactly Is R-410a Being Phased Out?

For years, R-410a was the go-to refrigerant for residential air conditioners because of its efficiency. But research showed that R-410a still contributes to global warming. As a result, the Environmental Protection Agency (EPA) implemented a strategy back in 2021. The industry will steadily discontinue R-410a to replace it with 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 shift will influence how systems are constructed as well as the best practices for HVAC maintenance. Both property owners and HVAC technicians need to plan 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 are categorized under the new "A2L" classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They're created to offer the same efficient cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is expected to be particularly efficient due to its GWP being about 78% lower than R-410a. Although R-454B refrigerant is actually more flammable than R-410a, updates to system manufacturing and maintenance practices will ensure servicing is just as safe to perform. Additionally, today's cooling systems using R-454B refrigerant are much more energy efficient, leading to substantial savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.

This change isn't simply about substituting the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it not suitable for use in older systems. Eventually, every residence and business using R-410a will be required to upgrade to one of the new systems.

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

Changing to the new refrigerants will not be as simple as replacing what's used in your home's 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 keep using your current R-410a system for now. Just know that as time progresses, the expense of repairs and tune-ups will increase as R-410a becomes harder to find.

Preparing in advance is the most effective way to stay on top of things. If your AC system is already aging, this is the best time to contemplate upgrading to a newer model that uses the new R-454B refrigerant. Plus, the staff here at LTS Plumbing & Heating Inc. can support you with upgrading with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Uncertain which refrigerant your AC system employs? In general, you can easily learn this information by examining the label on your outdoor unit. This label indicates the type of refrigerant, the model number and various other particulars about your cooling system.

But if you have difficulty reading the label or can't find your user manual, don't worry! You can always call one of the skilled technicians at LTS Plumbing & Heating Inc. to help you in figuring it out. Get all the details you need by giving us a call at 570-648-0748.
