	On the one hand, a dead compressor makes other things hard to
diganose.

	On the other hand, he certainly should have at least checked
static pressures, and if the system was flat, threw a test charge in
to find the leak ( and thus the bad coil ), etc, and discussed with
the owner the TOTAL cost of repair, as compared to the cost of
replacing the system ( with everything 100 % new and under warranty ).

	These days, a resi compressor change isn't going to make much
sense in probably most cases, on a cost basis.
