A2L refrigerants are often part of a broader category known as HFOs (Hydrofluoroolefins) and HFO blends. These refrigerants feature sustainability and energy efficiency, offering a reduced carbon footprint.
Advantages of A2L over HFCs
Compared to traditional HFCs, A2L refrigerants provide a multitude of benefits. One of the most significant advantages is their contribution to reducing the environmental impact. A2L refrigerants offer a GWP saving of up to 99.9% compared to many HFCs (Honeywell), making them a sustainable choice for modern HVAC systems.
The transition to A2L refrigerants also comes with performance benefits. These refrigerants are not just environmentally friendly; they also maintain strong HVAC performance without the negative side effects associated with legacy HFCs (Sensata Technologies, Inc.).
Another advantage includes a lower total cost of ownership. A2L refrigerants are reliable and efficient, often requiring minimal redesign of existing systems and equipment. This reduces both initial implementation and long-term operational costs. Enhanced availability and improved safety profiles also contribute to their growing market acceptance (Opteon).

Market Acceptance and Implementation
The widespread acceptance of A2L refrigerants within the marketplace is evident, particularly in supermarkets and buildings. The shift has been driven by several factors, including safety, efficiency, and environmental benefits.
Adoption in Supermarkets and Buildings
In recent years, the adoption of A2L refrigerants has grown significantly among supermarkets, industrial processes, as well as residential and commercial buildings. As homeowners, it’s crucial to understand this change and how it impacts your HVAC systems. Recognizing the safe usage, reliability, performance, and lower cost of ownership, many have adopted A2L refrigerants like Honeywell’s Solstice® L40X (Honeywell).
Numerous manufacturers have shown a preference for low-GWP R-454B refrigerant, which aligns with the industry move towards environmentally friendly refrigerant choices. This shift contributes to the overall reduction of greenhouse gas emissions, a point covered in our a2l refrigerant benefits section.
Success Stories with A2L Refrigerants
The successful implementation of A2L refrigerants in a variety of projects underscores their efficacy and benefits. For instance, a new French supermarket in Moissac and the first supermarket in Italy have reported substantial savings in lifetime emissions and costs compared to traditional refrigerants. These success stories provide a glimpse into the potential long-term savings for homeowners considering the switch.
Project | Location | Refrigerant | Savings Projection |
---|---|---|---|
New Supermarket | Moissac, France | Solstice® L40X | Reduced lifetime emissions and costs |
First Supermarket | Italy | Solstice® L40X | Reduced lifetime emissions and costs |

Regulatory Considerations
The transition to A2L refrigerants in residential and commercial HVAC systems is heavily influenced by various regulatory considerations. Understanding these regulations is crucial for homeowners and industry professionals alike.
Endorsement by Industry Organizations
Industry organizations like the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) have endorsed A2L refrigerants as acceptable for use in residential and commercial systems. Their endorsement comes with added mitigation measures due to the lower flammability levels of A2L refrigerants compared to A3 refrigerants. A2L refrigerants require higher concentrations in the air to become combustible, making them a safer alternative.
The Environmental Protection Agency (EPA) has recognized six lower Global Warming Potential (GWP) refrigerant alternatives classified as A2L. These alternatives include R–32, R–452B, R–454A, R–454B, R–454C, and R–457A, which are now approved for use in new residential and light commercial air conditioners and heat pumps under UL 60335-2-40 requirements (ICC).
Compliance with Updated Codes and Standards
Compliance with updated codes and standards is essential for the proper installation and use of A2L refrigerants. Regulatory bodies such as ASHRAE and UL have revised their guidelines to facilitate the adoption of A2L systems in HVAC applications. ASHRAE 15-2019 and UL 60335-2-40 now include specific requirements for A2L refrigerants, emphasizing the importance of leak detection systems to enhance safety and mitigate ignition risks (Sensata Technologies, Inc.).
Contractors need to ensure they follow these updated standards and the manufacturer’s installation guidelines. Compliance with ASHRAE Standard 15.2, in particular, is critical for the safe and effective use of A2L refrigerants. Proper understanding and implementation of these requirements will be pivotal during this transition phase.
During the 2021 Group A code cycle, several proposed changes were submitted for the International Building, Fire, and Mechanical Codes to support the use of A2L refrigerants. Fourteen code change proposals were approved, impacting the use of A2L refrigerants for human comfort applications, with specific proposals for the International Building Code (IBC), the International Fire Code (IFC), and the International Mechanical Code (IMC).
Standard/Code | Organization | Focus Area |
---|---|---|
ASHRAE 15-2019 | ASHRAE | Safety and leak detection |
UL 60335-2-40 | UL | Refrigerant classification and appliance safety |
ASHRAE Standard 15.2 | ASHRAE | Installation requirements |
IBC | ICC | Building safety |
IFC | ICC | Fire safety |
IMC | ICC | Mechanical safety |

Environmental Impact and Sustainability
The shift to A2L refrigerants represents a significant step forward in terms of environmental impact and sustainability. Understanding how these refrigerants contribute to reducing greenhouse gas emissions and mitigating climate change is crucial for homeowners.
Contributions to Greenhouse Gas Reduction
A2L refrigerants have significantly lower global warming potential (GWP) compared to many commonly used A1 refrigerants. For instance, R-454B, an A2L refrigerant, has a GWP of 465, whereas R-410A has a GWP of 2,088 (ACHR News). The Environmental Protection Agency (EPA) estimates that adopting A2L refrigerants could reduce greenhouse gas emissions by 876 million metric tons on a CO₂ equivalent basis through 2050, which equates to approximately 35 million metric tons per year over 25 years.
Refrigerant | GWP |
---|---|
R-454B (A2L) | 465 |
R-410A (A1) | 2088 |
By transitioning to A2L refrigerants, you can contribute to a significant reduction in greenhouse gases. This switch not only helps the environment but also aligns with regulatory requirements, making your home compliant with the latest standards.
Role in Climate Change Mitigation
A2L refrigerants play an essential role in mitigating climate change due to their lower GWP and enhanced energy efficiency. Studies show that refrigeration systems using HFO refrigerants like R-454C and R-454A have 10-year total emissions that are up to 25% lower than transcritical CO₂ systems, and up to 15% lower than propane systems. These refrigerants not only offer a reduced total cost of ownership but also feature better safety profiles and broader product availability compared to other alternatives like CO₂ and ammonia.
A2L refrigerants, particularly HFOs and HFO blends, offer a 99% reduction in GWP compared to older refrigerants like R-134a. This reduction helps in cutting down lifecycle emissions and supports wider availability of safer, more efficient refrigeration options (Opteon).
Transitioning to A2L refrigerants is expected to bring several economic benefits, including an increase in U.S. manufacturing jobs by 33,000 by 2027, a boost in U.S. exports by $5 billion, and a reduction in imports by $7 billion. These changes can positively influence the U.S. HVACR balance of trade.
