We use this for a guest room that is located to far from the whole house to reach and comfortable air conditioning. Although the house has a central unit, we found that there days where it can get too hot in there for some reason so this unit was the perfect solution! We’ve only installed and run it for a week and we could tell the difference of the room temperature from how it was before. Now, this room will get a lot more use because of this unit. Definitely recommended
