I had to replace an old AC unit for our bedroom and was happy to find this 8000 BTU unit available from Frigidaire. I had purchased a similar Frigidaire unit last year and was very happy with it. They are compact and light enough that I can install it by myself. Nice features, use the economy mode all the time. Cools down our bedroom nicely. Side window panels install securely and have an additional piece of insulation that you can cut and install in the slots provided on the side panels. I have 5 Frigidaire's cooling my house, so I do like the brand.
