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?
