Replacing Fins on AC Condenser?

[Samantha M.]

I met with a seller at their property today. The exterior AC condenser looked like it was in fairly good shape; however, on one side of the unit the fins looked like they were bent and damaged (possibly from a hail storm?). Like someone had dragged a stick across them. The seller is not sure how the damage happened (doesnt have kids, property hasnt been vandalized to seller knowledge)

My question is, how big of a problem is having bent/slightly damaged AC fins does that compromise the effectiveness of the AC unit as a whole? Also if I wanted to replace the fins what would be a rough approximate for cost?

I was under the impression all the fins do is protect the coils.

Thanks everyone
