If that is the extent of your input to the discussion, then I'm not sure anything you've written in this thread has been of much help - bordering on reportable trolling. If that is how houston techs are, then you are right, he's screwed even thinking about it.
Thanks for your compliments, this is why we Pro's are so far apart on some things, the condemnation we get just for disagreeing with someone that's not even in the same market area, to know the pro's and con's of installing a system like this here. I would not limit this idea of unknowledgeable techs to Houston, my guess it's prevalent in a lot of areas, except in your area. You should pack up and come down here and prove to us old dumb redneck a/c dudes how it's done, all I have heard is talk, what is it that some say, talk is cheap?
