I am a senior and will be using this portable ac unit on my 3-season room. Assembly was a easy process and instructions were easy to follow. I love that the air flow on this unit because of the many options. I chose the flow towards the ceiling on a slight angle away from the seating area, so you don't get a blast of air in your face or body. I used it yesterday and was amazed on the low noise level. Best portable ac unit I have ever purchased.
