Thie Keystone brand is a terrible product. I bought this 4 years ago and it died. It was the second one, as first didn't work. Ordered a replacement last week. It didn't blow cold. Now I have to return this 70 lb monster since neither mfr nor best buy will send ups to pick up. I'm buying a different brand and not from best buy s their service was non existent
