Come to think of it the unit in my pickup camper is inside and vented out and that's fairly quiet. I have a window air conditioner in my office and my window overlooks our deck , When I am out on the deck I can't hear people talking because of the background noise.
Tho you are only 5 - 6 miles away from me, Metigoshe must make a whale of a difference. I don't think that in the 12 years that I have been retired and at the Lake in the summer I would have ever turned on an AC unit ... but then our cabin is completely shaded by trees. We do face south tho and have a large picture window.
Those look like slick units . Are they loud and do they have a catch pan for condensation that needs to be emptied ?
