I bought this AC unit on 7/5/18.  It worked for 6 weeks then suddenly stopped cooling the room.   I called Black & Decker and they could not offer me any technical assistance to diagnose what is wrong with the unit.   The only option B&D offered is to send in a copy of my invoice to NY.  Then, 10 days later they said they will ship me a replacement.   6 weeks of use, plus 10 day of shipping time, is a pretty lousy track record for a new piece of equipment.
