R-454B Is Coming—Here’s What It Means for Your HVAC System

If you own or manage a commercial building in Utah, there’s a big HVAC change you should know about: R-454B refrigerant is replacing R-410A as the new industry standard starting in 2025. This shift is part of the U.S. Environmental Protection Agency’s (EPA) larger effort to reduce greenhouse gas emissions, and it will affect everything from new system installations to long-term maintenance costs.
Let’s break down what you need to know—and how All Around Cooling & Heating can help you stay ahead.
Why the Change?
The EPA is phasing down hydrofluorocarbon (HFC) refrigerants due to their high global warming potential (GWP). R-410A, the current standard in most systems, has a GWP of over 2,000. In contrast, R-454B offers a GWP under 500, making it significantly more environmentally friendly.
What Is R-454B?
R-454B is a next-generation refrigerant designed to meet environmental regulations while maintaining system performance. It is non-ozone-depleting and delivers similar efficiency to R-410A with a lower environmental impact.
Key Benefits of R-454B:
- ● 75% lower GWP than R-410A
- ● Compatible with many new HVAC units
- ● Similar operating pressures and capacities to current systems
- ● Helps meet EPA and global sustainability targets
When Does the Change Happen?
Starting January 1, 2025, HVAC manufacturers will no longer be allowed to produce equipment using R-410A. While existing systems will still function, sourcing R-410A for future repairs will become more expensive and harder to find.
That makes now the best time to plan ahead—especially if your commercial HVAC system is nearing 10+ years of age.
What Does This Mean for You?
If your building’s HVAC system uses R-410A:
- ● You can continue using it—but expect rising repair costs.
- ● Any new system replacements will likely use R-454B.
- ● Future maintenance may require specialized training and tools.
- ● Now is a good time to budget for upgrades or retrofits if your equipment is aging.
Safety Notes on R-454B
While R-454B is considered a lower flammability refrigerant (A2L classification), it still requires safe handling and installation by licensed professionals. All Around Cooling & Heating is trained and certified to work with R-454B systems, ensuring your business remains compliant and protected.
