3-4 round ceiling water spots near the vent closest to the air handler

My 25yr old inside Rheem air handler is in the closet on ground floor, not the attic. My condensation drain was badly clogged and flooded the floor beneath the handler in the closet. I had a tech come out and fix the clog and clean my unit as well, but I really couldn't get a definitive answer whether that condensation drain clog could of caused the water spots. I thought maybe the air handler might have lifted up some of that water & moisture and caused the 3-4 water spots now on my ceiling by saturating the insulation around my duct work? I know this is a lot of info but I'm at my wits end. I'm in SW Florida. Any ideas would be appreciated.
Thanks
