Big changes are happening in the HVAC industry in 2025, with older refrigerants like R-410A being phased out in favor of environmentally friendly options such as R-454B and R-32. These updates are part of an industry-wide effort to improve efficiency and lower carbon emissions.
At Coastal Air Solutions, we’re committed to keeping you informed and comfortable. Before upgrading your HVAC system, let our experts guide you through these refrigerant changes — so you can choose the best solution for your home and stay compliant with new standards.
Why Did HVAC Refrigerants Change in 2025?
R-410A has long been the go-to refrigerant for HVAC systems, but as of January 1, 2025, the industry is shifting to more eco-friendly alternatives like R-454B and R-32. These new standards, set by updated regulations from the Environmental Protection Agency, aim to lower emissions, minimize environmental impact, and improve energy efficiency. This is all to help create a more sustainable future for home cooling and heating.
New Refrigerants: R-454B & R-32
The HVAC industry is making a major shift toward environmentally friendly refrigerants, with R-454B and R-32 leading the charge. These innovative options not only reduce environmental impact but also enhance system performance and lower long-term energy costs for homeowners and businesses.
R-454B boasts a 78% lower Global Warming Potential (GWP) than R-410A, making it a cleaner and more energy-efficient choice that helps reduce electricity consumption. Meanwhile, R-32 offers a 68% lower GWP and requires less refrigerant, improving overall efficiency and cutting costs.
As these refrigerants become the new industry standard, they pave the way for more sustainable, cost-effective cooling solutions.
How Will the Change Impact You?
With the transition to R-454B and R-32 refrigerants, you may be wondering how this affects your home. Here’s what you need to know:
- Should I replace my HVAC system now? If your system currently uses R-410A, you don’t need to replace it immediately. Servicing and repairs will still be available, and R-410A can be reclaimed and recycled. However, if your unit is aging or due for an upgrade, switching to an R-454B or R-32 system will ensure better efficiency and future compatibility.
- Will new systems be more expensive? R-454B and R-32 units may have a higher upfront cost due to advanced technology and regulatory updates, but they’re designed for greater efficiency — helping you save on energy bills in the long run.
- How can I tell which refrigerant my system uses? Check the nameplate on your outdoor condenser; it should specify the refrigerant type. If you’re unsure, an HVAC professional can help identify it for you.
