well looks like the dogs have used that for a fire plug...looks like the suction line is frosting up a sign of low charge....time to seek bids on replacement..:biggrin2:
It's not going to be too early looking like that. Even if it works half way, it's still on borrowed time and using excess electricity. (There's going to be a significant amount of separation of the aluminum fins from the copper tubes. Even if the aluminum hasn't completely fallen off, it's not conducting heat well.)..
But there is a significant chance that it might still perform adequately, and then it would be money spent too early from an economic standpoint, to replace it now.
