Air Conditioner Fins - Once they are smashed, like by hail - can they be repaired?
The traditional view is that Air Conditioner Fins can be combed out; 
however, with the tiny and thin fins now a part of Air Conditioning
Systems, it is becoming known that there is 'no repair' to bring them
back to where they were before the hail event efficiency wise.  This is because the
air conditioning unit is permanently damaged and its efficiency will
not be able to be re-established.  The 'condenser units', in their
entirety have to be replaced.

Can you provide specifics as an engineer would relate to regarding the
specifics of this matter, either pro or con?

(Please avoid generalities or generally known surface information... thank you.)

Do you know of any legal cases where this has been litigated?

Take paperclip or popsicle stick.  Bend a few of the fins back to
their original position. Get magnifying glass and look at the
"repaired" fins for cracks. If there are no cracks heat transfer will
be the same as it was. If there are cracks, the heat will not jump the
gap and heat transfer will be much less.

If the unit has not been serviced in a while, other things like loss
of refrigerent or dirty housing and fan could be the root cause.

Your question is about to expire without having been answered, and you
might be disappointed.

A possible reason for that could be your pricing, which might be a bit
low for the type of research requested. Here is a link to guidelines
