- The Transition to A2L Refrigerants: What You Need to Know
Both R-454B and R-32 are A2L refrigerants, which are slightly flammable but non-toxic By comparison, R-410A is an A1 refrigerant, which is non-flammable and non-toxic
- The A2L Transition in Refrigerants: What to Know, How to Prepare
For the past several years, the HVAC industry headed into air conditioning season aware of the transition to A2L refrigerant technology Some planning also got underway across the industry, from OEMS to HVAC suppliers to technicians in the field
- What to Know About A2L Refrigerants, From Regulatory Expert Allison . . .
The HVAC industry’s switch to A2L refrigerants on January 1, 2025, will be here before we know it Here Allison Skidd, Director of Global Regulatory Affairs, explains what to know about A2L refrigerants and the new refrigeration standards, as well as how contractors can prepare
- What is A2L Refrigerant? - 2025 HVAC Regulations
A2L refrigerants are a class of refrigerants that are mildly flammable, have low toxicity, and have a low global warming potential A2L is an ASHRAE safety classification The “A” stands for non-toxic, “2” stands for flammable, and “L” stands for low burning velocity
- What You Should Know For The Transition To A2L Refrigerants
In 2025, the A2L standard for HVAC refrigerants mandates a Global Warming Potential (GWP) of under 700 The low GWP of A2L refrigerants can increase system efficiency and lower emissions by reducing energy consumption While slightly more flammable than A1s like R-410A, A2Ls are significantly safer than A3s such as propane A2L Cylinders
- What Homeowners Need to Know About the New A2L HVAC Refrigerant . . .
A2L refrigerants are a new class of refrigerants designed to replace older options like R-410A These refrigerants are part of global efforts to reduce the environmental impact of HVAC systems by lowering their Global Warming Potential (GWP)
- Understanding A2L Refrigerants - Fieldpiece Instruments
Many of these lower-GWP refrigerants are considered mildly flammable with an ASHRAE Standard 34 designation of A2L The transition to next-generation refrigerant technologies is being aided by the EPA’s Significant New Alternatives Policy (SNAP) program which approves the use of low-GWP refrigerant for specific uses
- A2L Is Here — What You Need to Know - HVAC Answers
A2L refrigerants, as categorized by ASHRAE Standard 34 , have lower toxicity and flammability compared to other classifications The designation of A = nontoxic, 2 = flammable, L = low burning velocity makes these refrigerants the second-safest refrigerant category
