I can understand your frustration with them energy star. We install all Trane/AS products and our first few were a bit sketchy. I like them though after doing a few. We have had problems with the blower door latches, I think the new ones have a round knob now because it was an issue. Another kink they had to work out was the half@$$ terminal strip on the control board, it wouldn't make a good connection...you would wire one up and just a slight touch of the wiring external of the unit would make a bad connection. That I also believe has been taken care of by a newer term strip. Make sure you leave a few inches before your first bend out of the unit with the line set or else you'll be cussing that when you take the doors off.
