Drain line in AC pan needed to be blown out (so pan overflowed in attic and water leaked through closet ceiling) but this would not have been notable on inspection. So, knock on wood, 2 years going and no big issue. The two sweetest words I ever heard from the inspector after we closed were "dry basement".
I will say that if I have the choice, I won't do this again however. I don't believe I'll get lucky twice.
If you had a good inspector you would have been told to pour a half cup of bleach mixed with a half cup of warm water into the condensate line. This would have cleared the gunk from the line so that it would not back up.
Do this annually at least.
