I need to replace the copper tubing for my outside unit. Will this be
expensive, A friend tried to solder the leaks in the pipe but, It did
not work.

The pipe probably won't cost much, but getting a specialist in to do the
work likely will. The pipe carries fluids at high pressure and replacing it
is not a DIY job. However, if the copper pipe is failing, I would look very
carefully at the air handling unit and heat exchanger, to see whether they
are not also on their last legs.
