"I'm sure Carrier, or any manufacturer for that matter, would like to see what's being done with they're equipment."
The manufacturer could give a crap less what it looks like. As stated earlier the very installer of this fine abortion was made dealer of the year. That's almost as entertaining as the bag of hammers salesman who came into my office and said the Lowes and Home Depot crap is good for everyone because of brand recognition. My brand is me and my company and I am loyal to my customers and myself and the customers install what I recommend. The big brands think we are unable to think for ourselves. They need to realize that we are the purchasers-- not the homeowners. Whew!!! I can breathe now.
That kind of crap goes on here a lot. A lot of builders just want the lowest price, don't give a rats you know what about your quality service or good work. I can hardly compete in new construction for builders anymore especially the way the housing market has tanked. The hacks are taking it all over with their low ball bids and wrecking the industry for everyone else. If that's the kind of work they want they can have it as far as I'm concerned. Don't ask me to do it thay way though. You get what you pay for.
Remember, some poor fool has to work on what you install someday, and it might even be you.
