We enclosed our back deck years ago, and last October (2017) we had window installed and I put down a tongue and groove heart pine floor.  We live this room... but it was HOT and not usable in the South Carolina summer. We looked at possibly having a mini split unit professionally installed, but at nearly $4,000., that wasn't possible.  We purchased an 8,000 BTU portable AC unit, which we returned because it never shut off and didn't cool the room.  We purchased the Fridgdaire as it is designed for sliding windows.  It was easy to install, cools great, doesn't have to run long to get the room down to 74, our whole house temp setting.  It is louder than I would like, or this would be FIve Stars. Ignore the comment below about remodeling a kitchen... it was the closest choice.
