Update- after discussing with the tech at Mermaid they asked me to package the unit back (they sent a box and paid freight). I was promised to be put at the front of the list- which was the case. The expansion valve was sticking- which is what the tech thought he would find. I installed Friday evening and enjoyed a cool boat this weekend. Supply air is now a chilly 50 degrees.
Ultimately I'm very happy with the product and warranty service- but be aware that service work will probably require removal and shipping back. After 6 months, the freight will be at your expense as I recall.
