Which freon will leak from a smaller hole R-22 or R-410A?

The R-22 (chlorodifluoromethane), will leak from a smaller hole

than R-410A will. Sort of. Now that we've answered the question,

it's time to state that R-410A is an azeotropic mixture of

difluoromethane and pentafluoroethane. And the difluoromethane

component of the mixture is a smaller molecule than

chlorodifluoromethane, which is what R-22 is. But the

pentafluoroethane is a larger molecule than the

chlorodifluoromethane (R-22). If molecular size is the sole

determinate as to which "stuff" can get out, part of the R-410A can

get out a smaller hole than the R-22, but all of the R-22 can get

out through the "right sized hole" because it is smaller than a

constituent of the R-410A. It's your call. Links are provided.
