I bought this air conditioner to replace one I'd had for 11 years.  It was getting so loud.  At first I was not very happy with it.  I had water leaks on the floor.  However, I found a link on the website to request a service call and it was that easy.  The tech came out and found that the unit had gotten a bit out of whack in shipping.  He popped something back in place and it was even quieter than before.  No more leaks and I am very happy with the unit.
