Replaced a compressor on this ol' bird- a Goodman PGB048120. Went back with a scroll compressor, and retrofitted it with @bluoncommunity R458A even though this unit was not in their database. I changed the drier and schrader valves, but installing a txv was not an option for this emergency repair. The result was a total charge LESS than the original R22 charge, with no capacity or SEER loss, despite some flattened condenser fins, which explains why @measurequick wasn't happy with the higher than normal head pressure. She'll live to cool another day, maybe a few more.
