I purchased this unit 2 years ago and have been happy with it overall. Last night I woke up to a house full of smoke pouring out of the back of the air conditioner, I was able to get it down the stairs and out the door right before flames started coming out of the back of the vents. Almost burned my house down. Amcor is no longer in business and have left their customers with no recourse or ability to get a hold of them. Pick a different brand.
