How much freon does a 2 & 1/2 ton central ac system require

There is no set amount. It depends upon the coil sizes in the indoor and outdoor plus the length and size of the line set that connects the two coils.

The amount the unit uses is stamped (printed) on the outside unit. The copper line set and the evaporator use a little more. THis is not an exact answer because you have to look up the line set and evaporator numbers but think 1 to 2 lbs over what the condenser shows is a close number.
