    Stubborn Condensation Leak on A-Coil

    We've got an Improperly draining A coil in an American Standard downflow fan coil unit. Drain is clear.
    Maintenance guy allowed to filter to clog and no doubt some initial dust clogging the coil.
    It's been cleaned twice with green Diversitech light foaming cleaner from Michel.

    Condensate leak stopped and then started leaking again after a month.

    Is there a better or more effective coil cleaner worth trying?

    Anything else besides cleaning which could suddenly cause this 8 yr old system to develop a condensate leak?

    Fan is variable speed (non adjustable) and air flow does not seem to be an issue.
