Purchased nearly three years ago and run throughout the season down in south Texas on the gulf with no issues. Not going back to Dometic…

Bought this to replace my old Cruise Air AC in my 2008 Sea Ray 330DA and so far so good. This AC is much quieter and seems to blow more air than the original. Fit in basically the same footprint as the old AC and uses my existing 8-pin control panel.

As promised, this was a direct replacement for the DTU turbo unit I replaced. The drain fitting is in a different location, so I had to splice in a piece of hose to reach it. It works well and seems to be a little quieter than the old unit. The refrigerant leaked out after one year, but Citimarine replaced it immediately with no hassle. The replacement unit is cooling great during the hot summer we are having.
