2 ton a/c.units only. No copper or wires. Bought and installed in August for $1000 took down in November to repair wall and decided not to put back up due to us not planning on living in this house much longer. Unit worked great and the only issue is the clips that hold the unit down to the back plate broke that's why I'm selling so cheap. Still hangs on plate no problem just doesn't clip on bottom never had an issue with it. Would be a good garage or small shop a/c. I value it around $600 that's what I have it listed for on market place. Wtt for guns let me know what you got, but a few things I'm currently looking for would be a shotgun tactical preferred also looking for a small carry pistol but let me know what you got to trade worst I could say is no.
