The New Era of HVAC Efficiency: A2L R-454B and R-32 Refrigerants
Share
As part of our commitment to stay at the forefront of HVAC innovation, we will begin incorporating A2L refrigerants, specifically R-32 and R-454B, into our air conditioning equipment starting 2025. This initiative ensures that our customers benefit from the most advanced solutions in the HVAC industry.
What are A2L Refrigerants?
A2L refrigerants, including R-32 and R-454b, are mildly flammable, low global warming potential (GWP) gases designed to replace older, high-GWP refrigerants like R-410A and R-134a. These refrigerants offer a balance between performance and sustainability,
complying with new environmental regulations and positioning the HVAC industry for a greener future.
Why the Shift?
The transition to A2L refrigerants is driven by environmental goals to reduce the HVAC industry's carbon footprint. A2Ls are part of the phasedown of HFCs under the AIM Act and the Montreal Protocol.
Why We Love A2L Refrigerants?
• Lower Environmental Impact: Significantly reduces GWP compared to traditional refrigerants.
• Energy Efficiency: Can enhance HVAC system efficiency, resulting in much lower energy consumption.
• Compliance with New Regulations: Aligns with U.S. and global climate goals, ensuring your systems
meet future standards.
What To Keep an Eye Out For?
• Mild Flammability: Requires special handling and equipment for safe use and installation. Look for our A2L Safe tools and parts!
• Training & Certification: Technicians will need new training and certifications to work with A2L systems safely.
• Limited Compatibility: Older systems will not be compatible and could require replacement.
Key Deadlines:
• 2025: Distributors and contractors can continue to sell R-410A refrigerant and equipment
until the end of this year, but after that, new equipment may not be legally sold with R-410A.
• After 2025: R-410A will be available only for servicing existing systems, with stricter
limitations in production and sales, making A2Ls the primary choice.
