Default HVAC diagnosis

Does the man own an ammeter? Very useful in such cases. Clean the terminals
on top of the compressor. Try starting it again, and check the amp draw.
Might be bad compressor, or just dirty terminals. Is the compressor really
getting 220 volts?

We survived Ike in extremely good shape compared to others in the vicinity.
The only significant problem is the AC unit: the compressor won't come on.

My AC guy swapped out the start & run capacitors, bypassed the relay, and
checked all the obvious stuff. No compressor action. He theorizes that
power-line chatter at the storm's outset could have so confused the aged
system that it committed suicide trying to keep up.

His best guess is a seized compressor piston on this 17-year old, 3-ton,
Trane and he's checking with his buddies for a used condensing unit.

Observations and suggestions would be welcome.

Thanks.
