Rated 1 out of 5 by from Returned Two Units I bought this AC back in September and quickly realized that it is not cooling down the air. Called warranty and was told that I have to take it back to Best Buy in order to get another unit at one of their stores. I turned out that apparently, Best Buy doesn't have any ACs in stock and it will take several days for my order to arrive. Picked up another unit

Rated 5 out of 5 by from Great unit I brought this right before the heat way and of course it was not on sale however, it is a very quiet unit! For the power of that many BTU’s, it is one of the mmost efficient units ive owned. I was always kinda scared of Frigiadire Appliances, but this gives my hope again. I recommend anyone who buys this unit. It does well for the den and living area of my home.
