AC - sound levels -new units?

[BackofBeyond]

question for the owners of the newer units with the updated AC's. Our 2018 LEII came with the std Dometic - loud as heck - really obnoxious when trying to sleep. Does anyone have any experience with the newer versions like the 48 v Houghton on the Apex, or the ones on the LEII.  I must admit that Apex looks interesting.

I rarely use my AC, due to the noise level. I’m not quite ready to change out my unit, but I hope to personally hear various new units, whether they are standard installs from OTT or upgrades by individual owners. This summer I was surprised by the quiet operation of the Chill Cube installed by @jd1923 in his refurbished Oliver. There are some notes in the forum about different new AC systems, but I think these notes are scattered around.

We updated our Dometic last year when Oliver was giving a deal on the Truma Adventa units.   My wife hated to spend the money, but she was happy after the unit  was installed.  We have a Lagun table, so it has become the table we eat at, play cards, and holds drinks and snacks while we watch Movies.    The difference was incredible.  We can carry on a normal conversation without raising our voices sitting on the beds at the Lagun table.  Watching a movie is no problem.  Sleeping with the AC on is a little loud, reminds me of staying at hotels with the AC units in the wall. you don't really notice them until all is quiet.  As @Boudicca908 said there is information about different AC units on the forum.  Some have even included -dB noise levels.

We have the Houghton (12V) on our 2027 Elite II. Although we do not have anything to compare it to, the Houghton seemed very quiet. You know it is on, but we could easily hold a conversation while it was running.
