We had the grommet kit put in at Goshen and it made a huge difference. It took away some noise but the best thing was it took away the vibration.

Here is the Grommet kit that they speak of. I have it on my Columbus it quiets the bedroom A/C it down a little but not much.

OK, so I'm a 'junior member' (feel like I should be wearing knee-length trousers, or sumthin'), but I've been RV-ing many, many years. After reading what a 'babe-magnet' these Columbus units are, I figured it might help me find one.....

Anyway, in the course of shopping for a replacement for my M.Mountaineer, it's become clear that Dometic is pushing their new, high-output, residential-style, ducted AC system with roof cold-air returns.

MFGs always want to go with the latest & greatest, and I like the theory...biggest benefit is an AC system that is supposedly quieter than a gnat fart. Reality, however, is that these systems have only been in the field a coupla' years, or so....I'm wondering about owner experiences with reliability....any takers?

Thanks!
Woody Hayes' picture on the front cap will surely attract a lot of chicks. Can't miss.

Barry,
I watched them do it and it can all be done without messing with the Freon system. The whole unit unbolts 4 bolts and 2 wire connections and then you can remove the whole thing. It took them about 15-30 minutes

As the duct work in the bedroom is connected to the living area, I just use the AC that is not where I am. When I first arrive I'll turn on both zones to cool off the unit. But after that, one of the unit's has been enough to maintain temp. So I'll turn on the AC in the bedroom when I'm in the living area, and at night, reverse this. I still get plenty of air throughout, and much reduced noise.

We tried that, but in our RV there are separate temp sensors for each zone and our bedroom was getting too warm with the living room AC only. (I know, I could just turn that one down more...my friends keep reminding me that I'm not paying for the electricity, but conservation is in my blood.)

the Dometic in my 36RE. 36CKTS, ridgeview were all Dometic units that would make as much noise as a freight train, just the nature of the Beast. if you want quite go coleman mach.

I don't have a Columbus but I do the same thing in my Sabre! Works great!
