[This review was collected as part of a promotion.] I didn’t realize how big this unit was. It does cool/heat a room fairly quickly. I did not know that it had a line to drain out of the window. I’m not a huge fan of that component. We did love the smart feature it offers. It was not too loud either.. Tressiej_2843. Sun May 18 2025
