Doesn't sound likely to me. I looked it up and what happens is that over long time periods in sunlight, CFCs lose a chlorine radical, and that chlorine radical lives for a long time and catalyzes ozone to turn into normal oxygen molecules. So it would only even possibly be effective if you have so much CFCs and so much light that it builds up a bunch of chlorine, enough to get rid of all of the ozone. My guess is that even if those reactions occur in the context of a home (which seems like a big if) they'd be so slow and require so much chlorine and CFCs around that you'd be dead before you could celebrate. Not to mention you'd have to be releasing CFCs in ~every building constantly, which would destroy the ozone layer orders of magnitude worse than we did decades ago.
