Title: works as a heater but not as an air conditioner
Review: We bought this unit for its A/C function but it has failed miserably. It hardly cools a room of any size. After 2 hours, the most this unit would do is to drop 3 degrees Fahrenheit in a small corner of the room while the rest of the room's temperature remains unchanged. One of the main problems might be due to the heat that its hose radiates. I have used insulators bought from the hardware store but they didn't help. The hose temperature can reach as high as 130 degrees! As a heater, this unit works fine. Noise can be unbearable, however.
