I just bought this window unit last July, and right away it was installed wrong. (not by a professional, by a family member who said he knew how) It is tilted so that water leaks into the house. Since we live in such a remote area, calling a professional would have cost me big bucks, so I tried to keep something under it to catch the water and left it at that. Other than than that, I cleaned the filter once per week and it worked fine.
A few days ago, I woke up and it was working fine, left the house, came home in the evening to find my unit blowing room temperature air. Left it off for a few days because family member mentioned above said it could become "frozen". Ummm, ok?
Really bummed that I payed a fortune for this thing only to get a few months use out of it, since it wasn't used during the fall/winter/early spring months at all. Anyone know what the problem could be? (Advice to others: when asked if you want the 2 year warranty, say yes!)
