Sub is swapping Amana for Goodman
Well, Patman, are you sure you're not thinking of the old style cabinets? Until '06 they had the rod-style coil protection, now they have a complete steel louvered type, with solid corners. Looks about on par with the better units to me. The unit I have has a low press switch, which according to their ads they have always had.
Like I was saying, the component parts are identical or very similar in most of these brands, from a fairly small bunch of manufacturers.
But hey, I am certainly no expert or even a HVAC installer. You guys sure could be right, (I hope not!) I'll try to report back with any probs I might have.
