I bought this air conditioner after much research of window units. I am so glad I decided to buy this unit. I was so happy with this 15,000 btu, I went out and bought  two 8,000 btu and 0ne 6,000 btu air conditioners from frigidaire of the same genre. These ac's not only work great, they look good too. I am so glad I chose these ac's. [This review was collected as part of a promotion.]
