I'll remove the evaporator core for 2 reasons:
1) to check for metal shavings from the failed compressor, and to flush them out if necessary, &
2) to wash the squirrel crap out of the fins. I vacuumed out what I could while replacing the blower & resistor, but I know there's more. (This CAN be done withOUT releasing any refrigerant.)

Three of the case screws are hidden inside the foil heat sheild, and on this truck, their heads had rusted away. I had to dremel them off & then use vise-grips to remove the screw shafts later.
