Brian, as Alan wrote, go to the office and speak to John. He'll probably put Reese on it but he may bring in an outside contractor. I've been having some refrigeration issues and he brought in the local Adler-Barbor tech.
Bear in mind, however, that Bill and Petersea have the same valid point. Given the outside temps we've been having plus the unusually warm water temps, that will affect the functioning of not only the a/c but also the freezer/reefer assuming all are watercooled.
By the way, what mooring are you on? Look for me at CC-20.
