I've just installed the unit and have had it running for an hour and it is cooling the room down nicely.  It's 85F outside and humid.  It's comfortable in the house.  This unit replaces a GE that worked well for almost 11 years without any troubles.  We are hoping this one lives up to and beyond the expectation of the previous one.

The one thing that leaves us less than fully satisfied is the smart phone app.  The app never connects to the unit in the cloud.  If having a WiFi connection is important then this air conditioner may not be a completely satisfying purchase.  Check the ratings on the app for whatever appliance you are shopping for if the WiFi connection is a key factor.  It wasn't a major factor in our choice but it would have been a nice feature to have.
