Purchased this product to use in a spare/office room that is 180 square feet (maximum). The first time, I set it up, plugged it in, turned it to cool mode at 63degrees and waited about 15 minutes for it to cool the room. 3 feet directly in front of the AC blew cool air, the rest of the room stayed warm - I say warm because it was 78 degrees. I tried it multiple times since then at different temperatures, to no avail; it's a 3 feet and done air conditioner when at 8,000BTU, it's supposed to work on a 350 square foot room. I am highly disappointed and it is too late to return the product. The AC did not in any way measure up to its specifications or stated purpose. I heard rave reviews about Frigidaire hence the purchase, but this product has been found wanting. Hoping Frigidaire can rectify this in some form.
