Was able to get some shots, but hard to get the whole system.
Here is the transisiton they made from the A coil to the supply plenum. Just below is the main return air box that runs parallel to the unit to the far end where the main return air plennum is. (don't know why the house was originally built that way and plumbed, but have to deal with it. Seems to help keep the motor noises down quite a bit, if nothing else.
Here is one that shows an overview of the completed system. The shiny stuf is new supply run and a larger return. The pipe coming just under the furnace is a huge supply line going into the living room and branching off to kitchen area downstream.
The center is the furnace (on it's side) to the left is the A-coil and supply plennum. To the right of the furnace is the main return air attached to the new large air filter.
This pic shows one of 3 VERY large supply lines with a smaller Y takeoff to another smaller duct.
I have NO complaints with the system performance! It cools down quickly and the fan starts slow, ramps up to a higher speed for 4 or 5 minutes, then ramps down to just barely blowing. I surmise this is the way it is supposed to work.......

Don't need to cheat a customer ot make a high profit margin.
Simply charge the margin you want. If a customer thinks the price is too high they can go to the next contractor.
The compressors aren't make special order for the manufacturer.
A bid sheet would do you no good. Since every install isn't the same.
Usually the people the most paranoid about being cheated. Are the ones that cheat others.
If you think an HVAC contractor is trying to cheat you in anyway. Simply use another contractor. Sooner or later your bound to find a cheap one.
Weather he charges enough that he can spend time checking to make sure things are right or not. Well, probably not.
But, you weren't cheated by the high priced contractor that has the tools and skill to check the system out right.
If your contractor has the time to explain to you what the differences are between his brand and system layout and teh other proposals you got. You got a good contractor, and will most likely have a quality install.
Sites like this shouldn't be answering brand quality questions, If you ask your contractor the same questions your asking here.Contractor locator map
How many times must one fix something before it is fixed?

How do you select a contractor?
I can't speak for anyone but myself:
I promise I don't use up 90% of my free time to come on here and learn about HVAC/R and discuss different topics then when addressing HO's lie straight to their face. I promise my free time would be worth way more to me than the feeling I would get from cheating someone for free
