We are modifying the ductwork off of the main compressor under the dinette seating area. In the models after 2020 and I believe starting in 2021, Jeanneau made three different vents off of this unit under the seat, one in the dash that is forward towards the bow of the dinette, and one in the boats molding that is aft of the dinette on the port side up high. In our version 1 of this AC system, there is only a vent under the seat, which does a really poor job of cooling the saloon in any warm climate. We are going to split the ductwork and run it up that molding area to a vent which seems fairly simple, but I would like to see some pictures of that from somebody who has it that way from the factory. If anyone else has great modifications to this saloon AC system ductwork they can share pictures of for everyone else; I know it would be really helpful as everyone I have spoken to has problems with the version 1 of the AC on this boat cooling the saloon. Thank you!

I have a 2021 1095 that has the revised salon AC vent design. There is simply a plastic Y fitting in the insulated flex vent with one outlet routed up the aft corner pillar of the hardtop and the other going forward through the gunnel ultimately terminating in the dash forward of the dinette. There is no third outlet—only these two.
Note that the forward vent required a new fiberglass shroud to conceal the flex duct it in the cabin overhead underneath where the duct transitions from the gunnel inward toward the terminating vent in the dash.
Also, I will recommend that you focus as well on where the supply air for this unit is coming from. The design is such that it’s supposed to come from the aft-facing vent at the glass door. However, the reality is that it will also come from outside by way of the cavity under the port-side seating (which is in turn connected to the entire lazarette). This results in your system trying to constantly cool ambient unconditioned air rather than repeatedly cooling already conditioned cabin air.
I designed and built a plenum that forces all supply air to originate from the cabin and performance has noticeably improved as a result.
hope this helps…
