Unit was larger than I anticipated but that is to be expected for 11,000 BTU's. Rolls easy but not across carpet so be careful. Window adapters are pretty easy to set up but pay attention to which side is the exhaust. If you have to set it up in a narrow window where the ports are vertical. Be sure to put the exhaust on top or the hot air will get pulled back in the intake, since heat rises. Other than that, it is pretty quiet and the settings are easy to follow with the remote. Forgot, it is top heavy so be careful with small children around it because it can tip on top of them if they pull on it.

The installation was easy. I have windows that slide sideways, so the two hoses for in and out are one above the other. The first time I turned it on, about four hours later the water tank was full. That surprised me because I thought that the tank would slowly empty itself. So I got 1/4" vinyl tubing, and fed the water to the outside. Quite easy. The unit is about as loud as expected, and you get used to it. We play piano in the same room, it works fine.

I installed the AC as soon as I received it. I am using it in a backyard portable office building, without any insulation. The average temp is above 100 degrees on a good day. Within 5 hours the office had cooled to temp. that I could use it for the purpose of an office for the first time in two years. Not really sure why I waited so long to make this purchase. I have not used the heater yet, but I am certain if the AC works this good the heater will as well, The noise level is acceptable.
