Great Solution For Even Desert Heat! Nov 03, 2016

We installed this unit in a small studio type building located in the Arizona desert northwest of Tucson. Even with a large south facing window and plenty of other glass, it keeps things cool even with when the temperature is over 115 degrees. Fast cool down from high starting room temperatures as well. Cooling is accomplished with a minimum of noise.on any blower setting. I highly recommend this very effective solution for specialized cooling needs such as ours..
