I purchased this ac for a small room some might say it was bigger than needed but i didnt want to run the risk of having a weak ac. Even though its in in a small size room 12x12 it does cool down the room rather quickly (a couple minutes) its not as loud a review i had read about a buzzing sound honestly its in a small room so if it was loud id know. Overall im happy im just hoping it goes the distance in durability... Time will tell :)
