    Air conditioner noise level

    Hi guys, new poster here. The wife and I are looking at a 2021 Solitude 380FL tomorrow, weíve been looking at pics, reviews and YouTube videos, so we are up to speed on the general layout and workings of the units but what has us concerned is that the ACís arenít true whisper quiet ducted like we have on our Open Range. It seems strange to see the big AC grills exposed on a high end unit like this. I suffer from chronic Tinnitus and canít take a lot of constant loud noise. So my question is just how loud are these units? Itís still too cold up here in Ontario for the dealer to demonstrate them, and itís unlikely that I can convince him to hook up to a 50 amp outlet anyway. Thanks!

    Canít see an issue with running the ac. They can hook up power I am sure
    If not the ac at least the fans in the ac

    First, welcome to the forums. It is a great place with lots of helpful and knowledgeable people.

    In answer to your question, they are partially ducted. The grills are the return air. The cold air outlet is normally ducted through the "race track" ducting in the ceiling. I say normally because some models/locations (bedroom) can have the cold air dump directly from the AC to the room by opening the dump vent for faster cool down. Some models/location have the dump vents blocked for more efficient cooling. In either case, with the race track duct you can use one AC (say the bedroom) to cool off the other end of the trailer (say the living area). The AC units are on separate thermostats. We often run the bedroom AC during the day and run the main AC at night. If it is fairly warm/hot out I will usually set the two ACs about 2~4 degrees different, and use one as "primary" and the other as secondary. Swapping which is which between day and night.

    Only you can answer what is to loud or an annoying frequency for you. You should not run the AC at low temp. I have been told it is hard on the compressor motor. However, there should be no problem running the circulating fan at any temperature, and it uses much less current (i.e. easy to run on a simple 15A circuit). In our unit, almost all of the noise is from the fan. I find our AC (two Coleman Mach15 AC units) are not objectionable, my wife an I can easily have a conversation in the same room as a running unit, but they are not silent either. One thing to note; with the pandemic, many components are in short supply and all of the manufactures are substituting what they can get. If you order a unit, you many get a different brand or model of AC (or any other component) from what you see in a unit on the lot.

    Hope this helps

    Chris

    I’ve never been in any type of RV or sailboat where the air conditioner was a silent as a house. You may have to change your expectations. Some may be due to the duct size.

    That being said, some are louder than others. As was said it’s the fan you hearing. Some of the Ouse is also the resistance of the air forced into the very small ducts.

    I don't know how many AC units that rig has, but we have two (yes, even on our little 5th wheel). That way we can run the one in the bedroom while we're in the living room, and vice versa. Makes it much easier to watch TV without the AC in the living room running.

    I am comparing our current Open Range fifth wheel to the previous one which was a 2015 cougar 28sgs (lemon) the ac noise level between the 2 was night and day. It just surprised me that I would see an exposed ac like the cougar had in a beautiful rig like a GD Solitude.

    It's because you lose a lot of efficiency with remote ducted returns like you have now. Up to 20%. There us only 5 to 8 decibels difference between what you have now and the racetrack ducted system with Coleman air units that the Solitude uses.

    Your opinion may be different but we think they are quiet. Especially when the cold air dumps are closed so they use the ducting. If I was at the RV now I would let you know the dB level with an app on my phone. Perhaps someone who is at their RV could do that for you.

    @Shepstone We have the 2020 Solitude 372WB and find the air-conditioning noise totally tolerable compared to our prior RV units. I can actually sleep in the bedroom with the air running on low cool. I could never do that with our prior rv units. Is it house quiet? No, but then none are. Overall I think you will be happy with your choice. Grand Design makes a good product IMHO. Safe travels!

    I've heard (no pun intended) that the Furrion units are quieter than others. Ours has a Furrion, and we are pleased with the low noise level, but we are comparing to our prior older trailers with mostly ductless units.
