So far, so good. Easily cools the entire downstairs which consists of 4 large rooms - open concept. I can stay on energy saver and 72 degrees - with the afternoon sun hitting my kitchen and living room it never gets over 74 degrees. Being in southeast Oklahoma/Northeast Texas it is VERY hot and VERY humid for months at a time and this unit is amazing!! 
Haven’t gotten into all the bells and whistles yet but will soon.
One drawback is the unit is VERY heavy so you’ll need two people to move and install. My son and I installed in a couple of hours.
I would buy again :)
