If you have recently heard about changes in refrigerant regulations and aren’t sure how they affect you, you’re not alone. As of January 1, 2025, all newly installed HVAC systems must use the refrigerant R-454B. This change is part of a broader effort to reduce greenhouse gas emissions. Understandably, many home and business owners have questions—so we’re here to clear up some of the most common concerns.
Can I use the new refrigerant in my R-410A system?
No, unfortunately not. R-454B and R-410A are chemically different and operate at different pressures, which means they are not interchangeable. If you want to use R-454B, you’ll need to install a system specifically designed for it.
Can my R-410A system still be serviced?
Yes! Even though new R-410A systems are no longer being manufactured, the refrigerant itself hasn’t disappeared. While its availability may decrease over time, R-410A will still be accessible for service and maintenance for many years to come.
Is the new R-454B refrigerant safe?
Yes—when used correctly. R-454B is classified as slightly flammable, which is why you might notice cautionary labeling on the packaging. However, it’s safe when installed and handled by a licensed technician using compatible equipment. Modern systems are designed with safety in mind, and there’s no risk when proper procedures are followed.
Do R-454B systems cost more?
Initially, yes—but only slightly. Because manufacturers are adjusting to new technology and training requirements, system costs may be a bit higher in the short term. That said, these increases aren’t expected to be significant or long-lasting.
Why is R-454B more energy efficient?
R-454B is better at trapping and transferring heat than its predecessors. This improved efficiency means HVAC systems using R-454B can heat or cool spaces using less energy. That results in:
- Lower utility bills
- Reduced reliance on fossil fuels
- Longer system lifespan
