I added an addition to my home in the form of a 300 square foot work shop. This room has a 9 foot overhead door and 2 windows as well as a walk through door to the garage and another to the outside. Since installation we have had over 3 weeks straight with highs ranging from 102 to109 degrees. (Waco, Tx.) 

This A/C has effortlessly kept my shop at 75 degrees. On occasions when I have had to open my overhead shop door to move a motorcycle in or out, it has recovered quickly. 
  The unit is super quiet. And I still have a nice view out of my windows.

I would give it 10 stars, but the only allow me to give 5.
