eleven year old residential split system, inside "A" coil fins are dripping condensate from the angled surfaces onto the concrete floor (vertical air handler) and not into the drip pans. have tried several different cleaners (including the foamy coil cleaner from lowes)on both top and bottom of both sides of "A" coil. have added
13 oz. of F22, hi press 150 psig, OAT 86 degrees.
suggestions appreciated.
