This live podcast focuses squarely on the ASHRAE 34 A2L classification and its implications across HVAC equipment, mechanical spaces, transportation, storage, and building codes. But what exactly are A2L refrigerants?

Named after their ASHRAE safety classification, A2L refrigerants exhibit mild flammability, low toxicity, and a low global warming potential (GWP). This category encompasses hydrofluoroolefins (HFOs) and HFO blends. A2L refrigerants mirror the operational characteristics of legacy refrigerants while presenting a safer profile compared to ammonia and hydrocarbon-based refrigerants.

As the world grapples with climate change, A2L refrigerants have emerged as a substitution for older, high-impact refrigerants such as HFCs and HCFCs in air conditioning and commercial refrigeration setups. A2Ls are pivotal in aiding businesses to meet global objectives outlined in agreements like the Montreal Protocol and the Kigali Amendment, as well as regional regulations such as the U.S. AIM Act, Canada’s ODSHAR, and the targets of the EU Green Deal.
