Title: nice unit overall
Review: I purchased this unit instead of popular less expensive units at local improvement stores mainly because I really like Amazon and I wanted a higher efficiency unit. This unit cools very well and has very nice controls for an inexpensive window unit. I actually installed this through-wall in my case, which was easy to do. The only reason I gave it 4 stars instead of 5 is the same as what some other reviewers mentioned...the drain holes. The drain hole is located towards the front of the unit at a higher elevation that other places in the pan. This is why the unit "swishes" when running - the standing water is being moved around. This is simply not necessary. I took 15 seconds to drill a drain hole in the back bottom corner (taking care not to penetrate beyond the hole itself so I didn't touch anything and damage it internally. The water all drains correctly and completely and the unit runs VERY quiet now.
