Of course all these boats are different. In my case, there was no extra wiring, or hull penetrations, and the water lines ran to the same water manifold as the split systems used. The new self contained systems are so small, they will fit it the space occupied by the original split system air handler. My model Hatteras had terminal blocks also in the same space with the air handler, so the self contained systems were wired to the original Hatteras terminal blocks. There are no extra pumps either, simply the original wiring from the terminal block to the pump relay. Might not be an appropriate solution for some models, but it's an easy conversion for many.

Re: AC replacement cost/quote
Its funny how the original question of cost to have a split system replaced turned into such a different subject.

Re: AC replacement cost/quote
Especially when it's the condensor I need replaced. Thought about doing the self contained in my salon but then I'm looking at 2 12k units as my salon is a 24k and is split between the blower on port side helm and the other is stbd side in aft end table. On my old boat I had a 16k self c unit and it's was loud. The unit turning on wasn't too bad but the air coming out was very loud, I noticed my split units the air discharge is much softer.

Did you discharge the cooling water through a sea chest or a new thru-hull?

Re: AC replacement cost/quote
I replaced a compressor a few years ago. I bought it from a well-known tech that used to have his own forum. Unfortunately, he passed away soon after I bought the compressor. His advice was invaluable. I replaced the unit, wired and plumbed it, then had a local HVAC guy evac it and charge it. Its been running strong ever since. As stated, a decent DIYer can replace a compressor, but you need to know what you have, what to replace with, and if the rest of the system is okay before you just jump into it. You don't want to go to all of the work and expense just to have it fail again in a short time because of something unforeseen that you never knew about.

Re: AC replacement cost/quote
The air noise is because it's not ducted right.

Re: AC replacement cost/quote
There wasn't much duct on my old boat, maybe 18 inches. Has any 53MY owners converted the split salon Ac with self contained units?I think pascal has done some major rehab work.

Re: AC replacement cost/quote
4 years ago I replaced the failed forward saloon split with a 16k Marvair which defenser had on sale for $999. It worked ok but the compressor was a bit loud.
Last year I removed everything and installed a pair of 36K BTU chillers in the ER and 5 air handlers. I love it. Boat gets real cold and since the chillers work together I have redundancy.Pascal
