Hydrofluorocarbons (HFC) contribute to ozone depletion and global warming

A class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion. According to the model presented in a new NASA study, their impact is such that HFCs will cause a 0.035 percent decrease in ozone by 2050 and contribution to global warming by all HFCs could be as large as 20 percent that of carbon dioxide.

I'm an AC technician for years technicians have been (venting) HFC's into the atmosphere because they told us they were
"SAFE" for the ozone. I can't even phathom how much HFC's have been carelessly vented into the atmosphere just in my years as an air conditioning mechanic. Terrible we all got government-certified from the EPA and they told us that they were ozone friendly. What a shame.

Please explain to me how a gas heavier than air can effect the stratosphere? It is like trying to get a rock to float from the bottom of the ocean.
