Interestingly, there is little agreement on which models are quieter. I have been doing a bunch of research and one person says Coleman is quieter, the next says Dometic is quieter, the next says domestic sounds like a jet taking off, Furion now has one.... Crazy that the manufacturers dont post DB ratings so you know factually. Trying to find anyone with inventory of all the pieces is a challenge as well. I am quickly thinking this might be a spring of 2021 project at this point. Another 45 days here in PA and I likely will not need the second AC anyway.
