Cold and Hard Facts Refrigerants Q & A- April 20, 2023

Do A2L refrigerants give off more harmful chemicals than A1 refrigerants when they burn?
No, hydrofluoric acid (HF) is produced during combustion of all fluorocarbon refrigerants (including R-410A, R-22 and A2L refrigerants). They will all produce similar amounts of HF. Hydrochloric acid is produced during combustion for previous generations of A1 refrigerants with ozone depletion potential, such as R22, but it is not produced during combustion of HFCs like 410A or A2L refrigerants like R-32 which do not contain chlorine.
