Introduction
Starting January 1, 2025, the HVAC industry entered a new era. Under the American Innovation and Manufacturing (AIM) Act, the U.S. Environmental Protection Agency (EPA) is requiring a shift away from high-global warming potential (GWP) refrigerants like R-410A. These older refrigerants are being phased down in favor of more climate-friendly A2L refrigerants, such as R-454B and R-32.
This change is designed to reduce the environmental impact of hydrofluorocarbons (HFCs) and support a more sustainable future for HVAC systems.
Understanding A2L Refrigerants
A2L refrigerants offer two key advantages: they are less flammable than older alternatives and have a much lower GWP. R-454B and R-32, for example, both fall well below the EPA’s 700 GWP threshold. This makes them more eco-friendly and better suited for today’s energy-conscious buildings.
First Co.’s Proactive Approach
At First Co., we’ve taken this transition seriously—and we’re ready. Our team has worked ahead of the curve to ensure all our current equipment is A2L-compliant. From day one, our product lines are built to support both R-454B and R-32 refrigerants.
We haven’t just adapted. We’ve designed our systems to meet these new standards confidently and completely—delivering the performance, safety, and compliance today’s customers expect.
What This Means for You
- For Homeowners: Your current system using R-410A can still run. However, if you’re installing a new unit or replacing an old one, it must now use an A2L-compatible system. Upgrading to R-454B or R-32 helps protect the environment and ensures you meet all current regulations.
- For Service Contractors: The shift to A2L refrigerants brings new handling and servicing rules. If you work in the field, be sure to get trained and certified on the proper use of these newer refrigerants to ensure safety and compliance.
- For Building Owners and Developers: Installing A2L-ready HVAC systems in new construction or renovation projects isn’t just about following the rules. It also adds value by reducing environmental impact and appealing to tenants who prioritize sustainability.
