Terry,
I installed two of them about 5 years ago: a 16.5K BTU unit and a 12K BTU unit. They have been flawless, both in
cooling in summer and
heating in
winter. I chose them partly because of the
electric coil
heating instead of the usual reverse cycle
marine types (so, no moving
parts except the fan), because of the quality of their build and the accessories which Flagship ships with them, and because both the USCG and the Canadian CG use them.
Very happy with them so far.
Bill
