A:AnswerSkip using their installation kit, it save a lot of room, most windows slide sideways these days anyway. Use the provided foam. You are going to want to cut a 1x2 shim to stop the window from being slid open anyway. Fill-in above with wood. Seal seems with the provided foam. This is how I do my older 1217 model.
A:AnswerNo, width can be adjusted not height, I would look at a smaller BTU unit for that window. The 10000 BTU, still quite a lot, LW1022IVSM is 13" inches tall. I would get it instead.
A:AnswerIt is just more efficient this unit will not heat as well, like some units that cost most and are heavier, but it is the same technology as used in a more expensive mini-split system.
