I purchased this unit to replace an old unit that was about 40 years old. This LG is perfect. It puts out cold for sure. We purchased the sleeve and coil cover extra. We had to make sure the unit tipped away from the front. Some shims did the job. We got it in place, finished off and sealed everything.  We plugged it in and yee Haa. It handles 500 sq ft easily. We had it shipped to store to avoid any issues. No problems there. It is a nice ac that has more than enough giddy up for our needs. Thank you LG!
