I have only utilized the cooling so far but am pleased. 
My 2 main gripes are:
The instructions on removing the face cover  were inadequate and we were scared to break it. 
When eco mode is off the fan can be loud with a metallic sound.

Other than those 2 things we love it for our master bedroom. It keeps it very comfortable and is usually quiet. It has saved is a lot of money as we have not had to run the central air since we keep our main room very comfortable. 

I am pleased with the installation overall and it was much easier to put in the chassis first. Needs better instructions for taking the face plate off but other than that it was easy.
