After an extensive heat wave, we purchased this air conditioner based upon its ease of installation, simple controls and the BTU's necessary to cool our house. Are we ever glad we chose this unit, because within 3 minutes of turning it on, our house was essentially cooled down to the right temperature. We felt alive again, feeling all of that cool air seamlessly entering all the rooms with ease. The controls make it simple to use as a dehumidifier when you just wish to dry the air out, too. A red light comes on when the filter needs to be cleaned, which is also an easy task. If I could give 6 stars to this A/C model, I would.
