Ducted AC return air in fivers

What mid level fiver brands have ducted rather than direct return air to the AC? Does that lower the sound very much? I don't like the high noise level of the direct air return ACs.
  • It must depend upon your house design. Every house I've been around, the central air returns are ducted. Not true for window units, obviously.

    All I know is, in our present RV (Class C), it's darn loud. We are looking for a used fiver to put on a site, and I don't want to have to live with noise like that.

    Wow. Even household air isn't return ducted.

    Does that make cooling more efficient?

    Well here you go, my signature model has both ducted output and return aif for both units.

    FYI...I don't think the new Wildcats have that anymore. Although the return air being ducted looks nice and is a little less loud, I miss having the access to the AC unit from below.
  • Most ACs can be annoying in the confined spaces of an RV. To answer your question, in my experience, the ducted AC is much quieter. I set my 15K Dometic to auto, and it normally runs on low. It is much like your house, when temp is reached, compressor and fan shut off. I like mine, and it cools very well too!
