Look for the Leaf:R-410A is called an environmentally-friendly refrigerant because it does not contribute to the depletion of the earth's vital ozone layer, which provides a protective barrier against the sun's harmful UV rays.

Look for equipment marked with the leaf, signifying that it's charged with R-410A.
