Episode: A2L Refrigerant Facts w/ Jason Obrzut
Description: Jason Obrzut comes on the podcast to discuss A2L refrigerant facts. Jason is a member of AHRI's Safe Refrigerant Transition Task Force and author of the RACT manual.

So, the new A2L designation indicates that a refrigerant is relatively non-toxic but has a flammability value between 1 (low) and 2 (moderate). While propane (R-290) is a good refrigerant because it is natural and has low toxicity, it is very flammable (A3). Future refrigerants will likely fall under the A2L...
