I decided to install a brand new heating/cooling system.  I had everything professionally removed, the R22 evacuated out and the copper ends sealed to keep air and moisture out.  The air conditioner still works, in fact, I was running it before the new equipment was installed.  It is a 3 ton, R22 Goodman air conditioner.  I also have the inside evaporator coil that can be sold with it if I haven't sold it first.  If you have any questions, I can answer them by email or if you leave me your phone number, I can call you.
