First time poster.
Finally need to replace residential split system. CAC/LP, forced hot air.
Janitrol furnace (which is ok), Goodman A/C (10 SEER) (Model U-30, 2.5 ton)
I was considering moving up to a York 3.5 ton, 13 SEER system (Model PC48C3XN1).
Long story short, how much trouble is this going to be?

Why are you going up in size? Larger unit needs more airflow, more furnace fan output, larger ducts etc. Have you done a heat load calculation to determine the proper size unit? Try this one:
