Best and quietest ductless rooftop AC?

Take a look at the Attwood unit.Ours is very,very quiet. The dealer replaced it for us when we complained how noisy the Dometic was.I have a small fan in there that makes more noise than the AC.

X2 on the Attwood. WAY quieter than the other brands.

All the best as you make your choice.

X-3 on Attwood.

Thanks, guys. That sounds like the one. It is non-ducted, right? And what's the model number?

Good Luck.........I had always been big on Atwood but since Dometic acquired them in 2014, they have been cheapening the construction of everything across the board progressively into junk. The question is have they gotten around to doing it to the Air Command AC units which were designed by an Australian company that Atwood had partnered with? Even at the Australian Air Command website they now link you to Dometic brochures and info. I'd say get it and get it now, while you cross your fingers Dometic has not been playing around with the construction and components on a quest to reduce costs and fatten the black numbers on the balance sheet.
