I think mine has a one year warranty. It is an LG brand. It actually cools twice the recommended sq footage. It is 8, 000 BTU rated at 340 sp ft, but the cooling area is around 650 sq ft. It is usually about 105 degrees here daily but the unit will hold a temp of about 78-80 which is nice for this area of my home! I also saw an 80 or so dollar reduction on my electric bill which is nice. Duct tape came in handy when sealing the interior window area and his holding strong. I added a portable LG 9,000 BTU unit in our bedroom since the money savings has been good. The exhaust hose runs out the window. Again I have no use for the bag of screws, duct tape can fix anything (: It cools the room nicely and provides a good "White Noise" for those folks that like that. Me, Momma, and Baby do! I haven't had to run the central AC since late June, and at 100 plus degree daily heat. I just got the first electric bill for the usage time and it is much lower. Very pleased. I may add another unit to my daughter's room in about 6 months when she is old enough to declare it her bedroom. I should see a real cost savings when this high pressure system takes a break in September and the heat retreats.
