Great buy at a great price. This AC is magical! The install was pretty easy. Our window was smaller than the piece sent, but we were able to cut it to fit with a table saw. It’s extremely efficient and cools a large room quickly. We needed it for our living room which is 26’ x 21’ and our ceiling height is 25’. We had a fan but we don’t have central air. The room cools extremely fast with this unit. It is a little loud but I feel it last relative to other wall units we have in the house.
