2000 Ford Focus Ripped hose - Moisture damage?

Air Conditioning problem
2000 Ford Focus 4 cyl Front Wheel Drive Manual
----------------------------------------------------------------
A/C was not working for more than a year.
I recently found ripped hose on suction end, right before receiver/dryer.
Obviously all Freon has leaked out.

Should I expect moisture has damaged the system throughout?
Will I need to replace rec.dr. and/or accumulator?

Thank you
