Bought arc-14s a couple months ago in the heart of summertime and corona virus. It was special order in my area but shipped in under a week to my door. Beautiful unit. Heard many negative things about portable AC's in the past and decided to do some research on my own. The idea of a portable ac was intriguing... In the end, Whynters dual hose design and high btu output was what sold me on the unit. I have been extremely satisfied with just how cold and how quickly this appliance works. I have another 15000 btu window unit on the other side of my house. They balance each other out quite nicely, which was my intention.... But next year I might forget the window unit entirely and try moving my Whynter around more from window to window.... Maybe just buy another Whynter all together.
