the main air conditioner in the house went out and will coast a lot to replace, so decided to get a window unit to hold me out, i did do a lot of research and found this one and this unit is strong and it cools this house quickly and it dose not use a lot of electric 1kw per hour that is nice and too when it get to temperature it shuts down and it spins up a little to do a temperature check that is cool, so ya I am very impressed. love the remote and able to use the internet to start cooling before I come home.
