Anyone who’s checked out our blog for longer than twelve minutes knows that I’m not shy about messing around with our RV’s air conditioner. In Lance, I think we went through four different air conditioners(!) in search of the quietest cool possible. I’ve also been known to bust open sealed control boxes in our air conditioners to tinker with the controls to make them colder. So, it should come as no surprise to anyone that this simple install to make the air conditioner quieter was a sure thing once I learned about it. Behold!
The concept behind the RV AC Silencer is simple, and I understood immediately how it should help. That’s why I got it and started on the install so quickly. In the way of full disclosure, I actually purchased this silencer within minutes of learning about it. The folks at Wacko Products learned about it and have since refunded our money before even seeing this video. But honestly, now that I’m done… we’d buy one again.
First off – this is ONLY for ducted air conditioners, so it wouldn’t have helped us in Lance. But it’s perfect for Number One, since we already have the ducted air. The second thing to take note of is that there are different models of the RV AC silencer depending on which brand of air conditioner you have. We have the GE, so we made sure to get the appropriate model.
At the heart of things, the RV AC Silencer is a baffle – meaning it routes the air intake not straight up into the unit, but rather has it jog sideways in an expanded intake box. Not having a straight open pathway into the innards of the air conditioner helps a LOT with the sound. That intake box also has some sound absorbing material in it to quiet things down further.
There’s also some increased efficiency that’s possible with the RV AC Silencer. The kit comes with an electrostatic air filter element to replace the see-through foam filter that ships with. You can also wash the electrostatic element without fear of it disintegrating. I like electrostatic filters: I have one on my air cleaner in the shop.
And finally the last-last thing the RV AC silencer does is that it instructs you to seal up the direct discharge air conditioner output. Now granted, this means you won’t have that option available if you wanted to use that vent location. But since we like the ducted AC vents in our EKKO, we never planned on using that vent location anyways. (And to be completely fair, you could seal up this opening on your air conditioner without buying the kit… all you’d need would be the foil tape. But it’s nice that the kit reminds you to complete the job.)
So How Did It Work?
In my brief testing, the RV AC Silencer provided us with a dB reduction of about 2-3 db. That’s doesn’t sound huge, but remember the dB scale is logarithmic, so it’s more impactful than it sounds. But more significant than that was that both my lovely camera-gal Stef and myself felt like it was much less acoustically annoying with the RV AC silencer installed. I suppose this has to do with the frequencies that are attenuated. Imagine if you were trying to have a conversation, and I was standing next to you making a half-hissing, half-gargling sound. It would be difficult to carry on that conversation! Now imagine if I shut up. Much easier to talk. That’s the effect you get with the RV AC silencer installed.
And speaking of shutting up, that’s what I’ll do now. As for us, the RV AC Silencer is staying. As for you, watch the video and judge for yourself!
