Yeah, why not, if you are concerned about your privacy? I recently got my MacBook Air back from the repair for the same problem. It was a friend's place so I didn't really have much problems and I didn't factory reset, but I wouldn't really trust someone I didn't know about my sensitive data. I think you should wipe your Mac anyway, given how seamless Time Machine recovery is nowadays.
