Reduce Inside AC Noise

**rayhagedorn** · 04-09-2021, 03:19 PM

Like many, it seems when the AC kicks on you have to shout, and if the TV is on, you have to increase the volume. I've read about a product, the RV AC silencer roughly $185, that states it will dramatically reduce AC noise level. Would appreciate any feedback on this product, or any methods you have used to reduce AC noise inside the camper.
Thanks!

Well, our "method" was to install a second AC in the bedroom. That way, we can turn on just the one in the bedroom when we're in the living room and watching TV. Or, vice versa, the one in the living room when we're trying to sleep in the bedroom.

This will be my project next week. Two videos, depending on what brand AC you have. Looks to be about $30, and a couple of hours, at most.

@rayhagedorn I've done this mod. Two air conditioners, about $25, under three hours. Very noticeably reduced noise and increased airflow from the ceiling vents. I did the mod in the fall so the ACs have not been used since I did it and tested for a few minutes, but so far I'm betting it will be well worth the effort and low cost.

If you need a further nudge, I saw a post recently saying that GD has begun installing something like this at the factory. I haven't verified that.

Good luck.

Just got done doing the second youtube method I posted above - have a Dometic AC pretty much like the one in the video.
It takes longer than one would think. Not hard, just putzy - checking foil tape length needed, fighting to getting the paper backing off, etc.

The original tape job on my Imagine was actually pretty decent. But I took it off and redid it anyway. The sticky foam barrier used was not really sealing things at all. Replacing as shown in the video was a big improvement.

The hardest part was getting the long mounting bolts back in - with one side closed off, it can be a problem seeing/feeling how to get them back into the holes they go in to. Tip: do the two on the outlet (sealed) side first and just barely started, until you get the other two in.
Mine had no plastic tabs that needed to be broken off like shown in the video, so all good there.

It was 36 and snowing outside, so not good weather for testing the AC before and after. I was going to do sound readings, but decided it wasn't really valid. Did get the fan running a bit just to see.

Overall, I think it is a bit quieter. Not a dramatic difference, but perhaps enough to make the project worth doing. Total materials cost was about $19.

Best part using the foil bubble wrap - if I later decide that I miss having the main air dump, it will be super easy to trim the Reflectix away from the dump opening, making it useable again.

Dometic Brisk-Airs are loud-period. The Wacko product does work and help, and the owner is a good and helpful guy. However, realize it is half the price of an air conditioner! If our prior camper didn't have a circumstance where the Brisk-Air was being replaced under warranty every other season, I'd have installed a Coleman Quiet Series Mach, but the Wacko silencer worked insofar as bringing it down 6-8 dB.

Sure would like to know about this store that sells RV air conditioners for $400.
