I have a couple of Panasonic window air conditioners that I have stored for
several years with the front panels facing upwards. I switched to central
air a few years ago and I'm trying to get rid of them. I found one fellow
interested, but he and his brother claim that the way I have stored them
has caused irreparable damage. Something about the refrigerant eating
through the tubing and could cause leaking. This is new info to me! The
units are about six years old, and are the ones with the electronic
controls in the CW-XC series.

Is there any basis to their claim?
