“Great unit but shabby hardware”
I bought this Kenmore 15000 BTU multi-room air conditioner to cool off my small two bedroom apartment and it does that wonderfully. For such a large unit it is rather quiet and keeps the place very comfortable. However my issues are with the quality of the installation hardware that came with the unit. The first step in installing this unit to your window is to mounth these "L" Shaped brackets to your exterior window sill. These brackets are two peices and are adjustable and have a slot were the carriage bolt slides through. However the slots on my brakes were about 2mm too narrow for the square part of the carriage bolt to slide through. I'm not sure if the paint/powder coat closed this gap too much. Also the nuts that were supplied to attach to these bolts were "hollow" cheap nuts that I've never seen before that barely thread onto the bolts. Then these L shaped brackets are supposed to attach to the underside of the A/C casing were there are predrilled holes along the bottom. However only about 5 of these holes are wide enough for the supplied bolt to go through. The hole I needed to attach the bracket to the casing too was a small one so I had to drill out a larger hole. I don't see why it would be too difficult to make all of these predrilled holes the same size as the few in the middle. My advice to anyone who buys this unit is to have spare bolts and nuts to save headaches in installation.
