I think someone from Jarrett Bay would be very competent to do this. I have used them before and were a good outfit. Just up Core Creek from you.

Burt Ferebee (252-670-1009) out of New Bern and Danny Martin (910 799-9362) out of Wilmington both work there regularly and are both outstanding marine refridgeration and AC guys, I have used them both when I had my boat in Morehead.
I wouldn't use Jarrett Bay for this particular work, and I u$ed them for a lot of other thing$.
Thank you for the lead to Burt Ferebee! Such a gentleman. Came within a day and located the problem after a good deal of digging. A true pro. Danny was one of my first calls and he's retired now. We're up and running like brand new. Thanks to all who help out. Great team on this forum for sure.
