Had this problem with AC units in my days in maintenance.
If the fall from the drain pan is looped upward at any point condensation can form on the outside of the drain hose where chill drain off gathers. Otherwise a blockage is the likely source.

Is the drain from the condensation pan clogged? Mine sometimes does clog and I plumbed a "T" to the top of the drain tube with a hose that I can blow through to clear the drain. I secure the open end of this hose well above the AC unit when not in use. There shouldn't be any part of the AC that would drip outside the condensation pan.

Down here in TX my cruiseair has been working ot. ive got the drainage tube connected and snaking out the hatch, but it seems that in the middle of the night (of course) all the sudden it starts dripping from the unit itself... is this normal? a function of the condensation due to temperature differential? is there anything i can do about this/anyone else experience this?
