TXV to be changed or not
If I have a 3 ton evaporator coil (R22) with a TXV and change my original condenser 2 ton 12 seer to a different manufacturer 2.5 ton 13 seer does the TXV need to be changed?

You'll lose capacity and efficiency if you increase the size without changing the coil.
You should get a matching 410a system.
Why are you increasing the size? If the ducts are marginally size to begin with, a 2.5 ton may not get proper airflow. (especially if the air handler or furnace has a 1/5th hp blower motor in it)

The 3 t coil should be able to handle the 2.5t condenser. Since it is already installed, If I were you, I just check the delta-T in house and at the condenser, also SC or may be SH to make sure the system is running in good condition. If everything runs fine, there is nothing to worry about.
