Query: Works Very Well In Special Situations

I live in the Southern California desert. My home air conditioner system does not cool the house evenly, especially the west facing or upstairs rooms. I find this unit does an excellent job in bring down the temperature in those room by about 10 degrees. I use this unit all the time during the summer. I am able to set my home air conditioner at a higher temperature and save $$$. The unit will NOT cool down an entire house, or cool a room more than 10 degrees or work in a humid area. I highly recommend this product for these special situations.
