My wife and I own a 67 Chris-Craft Commander Express 38. Over the last four years we have made extensive upgrades to some of the following areas like the electrical system 30A to 50A, wastewater, head, freshwater system, front portholes, front hatch etc. I have tried to keep it as original as possible but also making necessary changes where needed.
This year we found that the old split system AC unit couldn’t keep the cabin cool even after running new AC lines and adding new refrigerant etc. As much as I would like to keep the old system, I’m forced to admit that she will have to go. I’m hoping that there is CCCC member who has already made the switch and has either installed a split or a self-contained unit. And who would have some suggestions and or advice on which unit, location (v-berth, salon) of new AC unit, insulated duct line(s) thanks in advance.
The original Cruisair split systems were dependable and in their day the best option. Today's self contained DX units provide equal dependability and allow DIY install. In most cases a DX unit is compact enough to install in same area the existing air handler is installed. You likely will find ability to increase overall capacity in same install space.
I was able to place a 16K BTU Webasto FCF where the existing airhandler was installed at the factory and gained space removing the compressor unit.
Look at Webasto and cruiser stowaway offerings. Easy install, both very reliable...you'll be glad you made the conversion
