I’ve put this unit through the test this past summer. Bought unit in June for our main bedroom upstairs. We have central air but the upstairs is always a little warm. This ac unit is a true champ. Very guilt, simple to operate, and comes with everything for a clean install. We had a very hot summer in Ohio this year. I left this unit running in our bedroom 24-7 to maintain 70 degrees and no humidity from purchase till the end of August. All I had to do is clean the permanent filter once a week and I was good. Love this little unit!!  Going to buy another one next year for the other room!! Thanks LG!
