If your existing A/C can handle the additional load, you can run a duct off your main supply trunk. This can be done without making any other modifications.
If you want or need a separate unit like the Mitsubishi Mini-Split then yes there are a lot of things to consider. Did you have Low E 366 glass put in, if so and your house is block and you have a 4" clearance between the ground and the concrete or 6" if it's frame you don't have to raise the floor. But.... the room will have to be brought up to a Class 4, which means added electrical outlets and blown-in insulation. All of this will have to be inspected as well. With the rule changes Sumter put into effect this year, it's much harder than before.
