I have a 90 Carat for sale in Seattle.  One of the potential buyers wants an estimate to get the AC blowing cold since she lives in a hotter part of the country.   My AC system appears intact, hopefully just needs a charge/0-rings.

Any recommendations?

Ideally a shop that won't automatically say "you need a new compressor".

I know a great AC shop in Berkeley, but that is like 750 miles away...
