Re: self contained a/c unit
The cost option of a all-in-one unit is appealing. The labor involved redirecting water hoses, larger water pump maybe and electric lines need to be considered.
When your done, that nice and quiet AC system is no more.
What is wrong with your split system? There may be hope and can avoid all of these mods.
This mod has been done and others will be chiming in soon. Just had to get my thoughts in.
Re: self contained a/c unit
I did this on my Chris-Craft Commander and regretted it, the self-contained units are a lot louder than the splits. Doesn't matter underway with the engine noise, but you definitely notice it with the engines off. The one in the master used to drive me nuts. That was almost 10 years ago maybe the technology has improved?
Re: self contained a/c unit
I m not a big fan of self contained but considering the savings and easier maintenance it is a viable option. Especially in areas where getting reliable air con service is difficult.
In the salon, the noise isn’t as much of an issue as it is in a stateroom. A few years ago, when the master SR condenser failed on my 53, I found a Marvair 16k self contained on sale at Defender for $999. Figured I had nothing to loose and the time I was evaluating long term options. At that point I had already combined the VIP and the master so is installed it in the old VIP closet, about 15’ from the bed headboard. It wasn’t too loud but you could definitely hear the compressor when it ran. I kept it for about a year until I converted the boat to chillers. I just can’t imagine having one under or right next to the bed in typical installation.
I don’t know the layout of the 43 but I imagine it s not a long hose run from the pump in the ER to where you would install it so running the hoses and the power may not be too hard. The hoses will not be much thicker than the existing copper piping and their insulation.
What you may have to upgrade is the sea water pump depending on how long the hose run is and how much higher the unit is installed compared to the old condenser
As to which model to order, you need to measure the space and see what will fit. Check out defender.com they usually have good prices on self contained. Personally I would stay away from anythjng made by cruisair dometic because of their proprietary controls and boards.
Flagship Marine in Stuart has a line of self contained. All made in the US and nice solid construction. Excellent service as well. I got my chiller system from them
Re: self contained a/c unit
I did this conversion. I installed a 16k in that space in the salon. The trickiest part was forming the plywood box to isolate the unit from the rest of the hollow wall. I put a 6 inch Y on top of the output into two 4 inch ducts. Under the windows. Significant improvement of air distribution.
Noise was an issue when watching TV. Sooo.
After a few years I relocated this unit into a space under the starboard V bunk and ran the ductwork back into the salon. Very happy now.
Re: self contained a/c unit
This popped up in a Defender email today. Pretty reasonable for a 25k BTU

I have the microair easy start soft starter on it too.....my 18,000 btu/hr or 12,000 can run on a honda 2000w inverter generator.

Never heard of that brand but according to the link
- Marine-grade stainless steel frame for durability and longevity
Maybe the frame is stainless and the pan is iron
Re: self contained a/c unit
The brand has been around for ever making diesel heater for boats, sunroofs for cars as far back as the 60s etc. it s no guarantee obviously but the claim the frame is SS. I can imagine any manufacturer using steel pans and frames
Ocean breeze was great, I had 5 of their condensers on my boat, but at this point the new ownership is a big u known. Personally I wouldn’t take a risk.
Re: self contained a/c unit
Webasto ???
Now owned by Dumbetic corp.
Bumbetic Corp did not want to even compete with the cheapest and shitiest A/C company so they bought them also.
Expect the same support as the new lowered standard of all the other products this company has bought up.
Again I state, when you can not compete on the better markets, Purchase your competition and bring them down to your shitty way of business, The Dometic way..
