I was a Lennox dealer, installer and repairman about the time that unit was installed and the units then were made with heavy duty copper. I repaired and even installed used refurbished units. Giving that the rest of the unit is in good condition, replacing the compressor can renew the usefulness of the system. It is unlikely new units will be built with the equivalent; although a new unit brings a new warrantee and can be insured for further service.
