Has anyone replaced or removed the split system A/C units on a 61 motor yacht. I am wondering how hard it is to access the refrigerant pipes from the compressor to the evaporators to remove them. I want to rip out the current system and replace with chillers and run new insulated chilled water lines. Someone told me the copper lines are screwed down all along the runs and are impossible to remove.

Re: A/C split units
Pascal recently installed a chilled water a/c system on his 53 MY. His report on this forum was quite
interesting. I think he ran new water lines rather than try to use the original copper. Pascal, can you
help this HOFer out.

Re: A/C split units
Indeed You can’t use the copper as it is too small. You probably can’t remove it either as so much of it is secured.
In my case since a lot of the cabinetry, exhaust, etc was removed running new insulated hoses was easy.
Not very familiar with the exact layout of the 61 but with the ERs in the center of the boat, it s not very difficult to run new hoses up to the salon or tobthe stateroom.
And it is well worth the trouble.Pascal

Re: A/C split units
Are the existing a/c compressors in the engine room? On my 63’ they are all under the galley in the generator compartment. I would think that would make it a bit more difficult to run hoses back to the Master Stateroom and to the aft air handler in the salon. Not impossible though, just harder.

Re: A/C split units
When converting to chillers you re starting from scratch so they can be installed either way. I considered the generator room but on the 53 had more space in the stbd ER, one in each corner. Doesn’t make much of a difference for the hoses. It just takes a couple of holes
I did install the chilled water tank and circulation pump in the gen room thoughPascal
