I was desperate for a cooler kitchen and have small slider windows. This fits perfectly. I can cook and bake now without heating the apartment, which is always hot due to direct sun hitting the roof (poor insulation) and of course hot air rises, so being on the second floor is a problem in the Summer; especially with no shade trees and a missing awning to block that western sun. I have two portable room ACs; one in the LR area and my BR. The Frigidaire helps keep the LR cool with a tower fan blowing cool air out from the kitchen. So grateful to have it.
