Anyone dealt with a replacement cooling system coming in with very different tonnage and pricing in Atlanta?

I'm in Atlanta, Georgia and dealing with a 15-year-old replacement cooling system in our older detached house. Over the last three days, it has been coming in with very different tonnage and pricing and we're now noticing the upstairs stays noticeably worse than the main floor.
One contractor quoted $287 for repair, while another jumped straight to a $14,273 replacement because of the age. The weather here has been dealing us humid summer load, so I do not want to wait too long, but I also do not want to approve the wrong scope.
If you were comparing bids on this, what would you want checked first? I especially want to know how much weight you would give to load calculation, duct condition, insulation assumptions, and line-set reuse.

What helped us most was breaking the quote into labour, parts, warranty, and optional upgrades. The expensive bid looked very different once it was itemized. We had a related issue with our replacement cooling system in Atlanta. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

From a contractor side, I would not approve a major repair or replacement without test results that line up with the symptoms. For a replacement cooling system that is coming in with very different tonnage and pricing, the first things I would ask for are load calculation, duct condition, insulation assumptions, and line-set reuse. If the contractor is recommending bigger work, ask them to explain which measurement supports that recommendation and whether they ruled out airflow or controls first. In Atlanta, Georgia, pricing can move around, but the diagnostic process should still be clear.

If this landed on my schedule, I would want to document the core readings first and then explain exactly why the repair does or does not make economic sense.

We had something similar and the turning point was asking each company for the actual readings in writing instead of a verbal explanation.
