Frustrated with Dometic

I always install a filter in the small pressure line it will help if a compressor goes bad to capture debree.

My thoughts also.
Marine units probably won't last that long, just giving you an idea how many units we change out monthly and the associated problems with different compressors

They make up to 40% mark up on unit and parts. Biggger the part bigger dollars in their pocket. They want to drop in a whole new unit and go home. Swapping compressor is more work for less money. In a utopian world dometic would have a new unit on the shelf, but they don't. Get rebuilt compressor, run it til it fails, by then world will hopefully be normal.
I'm getting a new boat built, my chilled water units have been at the yard for a while. More than one unit has been borrowed for another boat that needed one now cause dometic couldn't get one for months. We did same thing on current boat when a self contained unit failed, borrowed one from new build that wasn't needed for few months. Life in the big city.

Ralph you've got your opinion I've got mine. We only repair our buildings units, not for anyone else. We want our tenants to have as few ac problems as possible. When a units compressor/ s are shot but coils are in good shape, we swap out for a new one if available if not a rebuilt. We don't screw around with old units that are tired. Many tenants are storing pharmaceutical products and cannot be above a certain temp for x minutes. Rebuilds have same longevity as new, period. Prefer new but that isn't always possible. Units up to 20 ton, package, 2 compressors.
These aluminum coils are TOTAL junk and should be banned.
As you know cleaning and drying is what makes for a successful compressor swap.

EXACTLY !!!

I have an old Cruise air unit 16,000 BTU.
The compressor size was actually a 14,000 BTU unit on there that’s what Cruise air used even though they called at 16,000 BTU they all seem to do that.
The actual compressor rating is lower than what the overall unit is supposed to do I don’t understand why this is but it seems to be at least back in the 80s.
Mine is a R22 unit.
Anyway it was a Tecumseh Compressor made specifically for cruise air so I couldn’t get the exact 14,000 BTU unit.
I had to drop down to a 12,000 BTU to fit in the frame / unit .
Myself and my Refrigeration guy put it in works very well it’s going on two years now.
We just had to change out the starters and the compressor take out the old braze in the new charge it and all was good including reverse cycle heat pump.
Oh mine are remote units. Not self contained.
Got my stuff from United refrigeration.

CR i’m getting tired of learning about this old boat stuff …
Why does it (boats, yachts, etc.)always have to be so complicated!
All I wanna do is turn it on and just have it work. Lol. I don’t want to know or learn a thing .
Never seems to work out that way.

Well very good to know. Lots of good information all around.
Guess for now it’s time to get a box fan and some block ice and set the fan behind the ice to blow across to it to get cool air….Lol!
