The outside unit should match the coil inside (sometimes it is inside
the air handler). But either way, if you have to replace the inside
coil to get it to match, you really shouldn't have to replace the whole
air handler, just the coil itself.

Maybe not, but with the motor and bearings around 20 years old and the newer
units going to varitable speed systems you might as well replace the whole
air handler.
