My wife recently informed my that she could not sleep with the noise of the roof air conditioners and that we would not be allowed to use them during the night anymore. Somehow I stumbled across the noise silencers from WackO products and decided to order some for my motorhome. Basically, you must have ducted air conditioning with the air intake exposed. You remove the factory air intake from the AC and replace it with one that has noise deadening and makes the incoming air snake around some. It also blocks off the rapid cooling vent in the factory grill. I don't have the instruments to verify the claimed dB reduction but there is no doubt in my mind that all but the lowest frequencies have been significantly attenuated and the noise is much more tolerable. It is much easier to have a conversation or listen to music now. And, my wife says that we can use the air conditioner at night now.

When you look at what they are the $200 price does seem to be high but when considering how much more enjoyable my RV will be now they are a bargain. To make up for the loss of the rapid cooling vent in the factory grill I bought and installed some extra vents in the ductwork that seem to do the job just fine without bringing back the noise. At this time there may only be kits for Dometic and Coleman airconditioners.

One place to purchase the WackO silencer

Could have saved a lot of money with astro foil and tightening up the mounting bolts and moving the control box out the way

I would buy her a tent, much cheaper and easier...

Have you priced a divorce lately? [emoticon]

If it was just about saving money I wouldn't even have this rig. I have no regrets about doing this and am looking forward to our next trip.

Might be a little cost prohibitive but our new Atwood AC is the quietest AC I have ever heard. It is easily half the DB of the dometic that was on our trailer before and out performs the dometic in every way also. It's as if Atwood designed it with noise in mind [emoticon]

We have the Base Air and a Non-Ducted Atwood AC. The Atwood AC is very quiet.

My thoughts exactly ... Camping/Rving should be a journey and not simply a walk in the park[emoticon]

$200 and the wife is happy.....well worth it. If I still had the Minnie trailer we owned, I would be ordering one. And, anyone with a ducted system should make sure that the vent at the main unit (used for quick cool down) should be closed if you want the AC to be quieter. I'm sure the OP already knows this...just a point of info for others.
