- 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
- 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 switch to A2L refrigerants brings along some additional requirements, which we outline below Why R-454B?
- What is A2L Refrigerant? - 2025 HVAC Regulations - 4 Seasons Heating Air
Starting January 1st, 2025, residential ACs and heat pumps must begin using a new type of refrigerant, known as A2L The HVAC industry is moving toward A2L refrigerants because they offer two key benefits: they’re better for the environment and they use less energy
- UNDERSTANDING A2L REFRIGERANTS - Honeywell
Though A2Ls will be a key component of refrigerant strategies of the future, Honeywell does offer a medium-temperature A1 <150 GWP refrigerant For details, read the Honeywell N-71 (R-471A) application guide ASHRAE Standard 34 classifies refrigerants into toxicity and flammability groups
- A2L Refrigerants: What Techs Need to Know - HVAC School
In recent years, ASHRAE has amended its system to account for mildly flammable, low-toxicity refrigerants ASHRAE sorts those refrigerants into the A2L category, including R-32 While A2L refrigerants are far less flammable than A3 and even A2 refrigerants, we still need to take extra precautions that we didn’t need to take with R-22 and R-410A
- What 2025 HVAC Code Changes Mean for A2L Refrigerants | DuraLabel
A2L refrigerants are a class of chemicals defined by ASHRAE Standard 34 as having low toxicity and mild flammability Examples include R-32, R-454B, and R-1234yf These refrigerants are gaining traction because they offer a significantly lower global warming potential (GWP) compared to older refrigerants like R-410A and R-404A
- Understanding A2L Refrigerants: What Homeowners Need to Know
But what exactly is an A2L refrigerant—and what does it mean for you as a homeowner? This guide explains what A2L refrigerants are, how they compare to traditional refrigerants like R-410A, and why making the switch is important in 2025 and beyond
- Understanding A2L Refrigerants: The Future of Cooling Technology . . .
A2L refrigerants are a classification of low-global-warming-potential (GWP) refrigerants that exhibit lower flammability compared to traditional refrigerants The designation “A2L” indicates that these substances have a low toxicity level (A) and a lower flammability classification (2L)
