If you’re thinking about upgrading your air conditioning system, you’ve likely heard that older refrigerants are being phased out. As of 2025, manufacturers are no longer producing new AC units that use R-410A, a refrigerant that has long been the industry standard. Why? Because it’s time for something better—safer for the environment, more efficient, and just as effective at keeping your home cool.
Let’s take a closer look at the new refrigerants replacing R-410A—specifically R-32 and R-454B—and what they mean for your air conditioning in Lawrenceville, GA.
Why Replace R-410A?
R-410A has been widely used for years, but it has a high Global Warming Potential (GWP). As part of international and national efforts to combat climate change, new regulations are pushing for lower-GWP alternatives. That’s why refrigerants like R-32 and R-454B are now taking center stage.
Meet the New Refrigerants: R-32 and R-454B
R-32 is a single-component refrigerant that offers several advantages over R-410A. It has a much lower GWP—about 675 compared to R-410A’s 2,088. It also operates more efficiently, meaning your AC system can use less energy to provide the same level of cooling.
R-454B, another top replacement, has an even lower GWP of around 466. This makes it one of the most environmentally friendly options available today. It’s a blend of two different refrigerants and is being adopted by many leading manufacturers for next-generation systems.
Both R-32 and R-454B are classified as “mildly flammable,” but rest assured, modern air conditioners are designed with strict safety standards in mind. When installed and serviced by licensed professionals like us, they’re just as safe and reliable as any past systems.
Benefits of Upgrading to a New AC System
Upgrading to a system that uses R-32 or R-454B offers multiple benefits:
- Improved Energy Efficiency – These refrigerants require less energy to cool your home, saving you money on utility bills.
- Lower Environmental Impact – With a lower GWP, these options help reduce your household’s carbon footprint.
- Future-Proof Your Comfort – As R-410A is phased out, it will become more expensive and harder to find. Upgrading now avoids those future headaches.
- Better Performance – Many new systems are designed from the ground up to take full advantage of these next-gen refrigerants, offering enhanced reliability and cooling power.
