This unit is perfect for our bedroom which is on the smaller side and, to feel comfortable, we rarely ever go higher than a 2 on the cool settings even when the temp is in the low 80s. It was relatively easy to install. But I definitely want to give a shout-out to customer service because our unit arrived damaged (the front grill was kicked in which would have made it difficult to remove and re-insert the air filter) and they were a great help in resolving the situation
