I purchased to cool a 'sunroom' in Maryland. The room is about 10x30 with a very high ceiling. The sun was heating the glass and making the room too hot to enjoy in the spring and summer, even though I had very heavy blinds on the window. This ac unit was a game changer. The cooling power allows me to finally enjoy my porch in the summer. Note: I have a heater in the room so now it truly is a 4 season room. Thanks for a great ac unit at a fair price.
