Hi, quick question. I have 3 window AC units, all different models and age.
One has a drain tube, and water regularly drains from it. It works great.

The other 2 have no such drain, and I never see any water coming from them.
Is this normal? One is a 2 year old Maytag, and it seems to run loud and not
as cool as you would expect. Not sure if its related. The manual mentions
nothing of leaving an angle to drain properly.

thanks
Bob
