    Nice unit

  2. Pete U. (verified owner)

    A very well designed and executed product. Installation instructions are very clear and product works just as advertised. This is our 3rd RV Silencer purchase.

  3. Darnell Jordan (verified owner)

    We cannot believe the difference. Out bedroom air conditioner was so loud. Now totally vented and helps the main air conditioner cool the living room and kitchen. Would do it again.

  4. normand Giroux (verified owner)

    not noisy

  5. Sylvester O. (verified owner)

    The hardest thing was sealing up all the little holes and places where ductwork was not sealed.

  13. Del (verified owner)

    Works as advertised, not a huge drop in DB but the frequency change makes the investment worth it.

  14. A. Michael Collins (verified owner)

    Very pleased with noise reduction. Worth the cost. Easy installation.

  15. Anonymous (verified owner)

    Relatively easy to install and was a 10 decibel in the noise level, which is a 50% drop in the sound.
    . Instantly obvious of the quietness. Would highly recommend this product.

  19. Wendy (verified owner)

    Installation was easy, product works as described. Really helped with noise reduction, and seemed to increase air flow.

  20. Sebastian (verified owner)

    It really works! Cut out easily 1/3 of the ac sound! I don’t have to crank up my tv volume now every time the ac turns on!

  21. TOM T. (verified owner)

    The AC silencer was great. It reduced the sound of the unit to a level where I can actually hear my wife. For that reason I am thinking of returning it!

  22. Mike Turner (verified owner)

    Worked as advertised. We can hear the TV now. We installed in a Thor Quantum Sprinter.

  23. Bryan K. (verified owner)

    I was absolutely AMAZED at the difference the RV A/C Silencer made. I did take a good bit of time preparing everything even created an air diverter that split the air coming directly down from the unit into each side where the ducts are located. This sealed off completely the airflow only allowing it to come out of the ceiling ducts. taped everything up good and even created a mounting bracket for the A/C control box (for touch screen control) that was just screwed in place horizontal blocking return airflow. Mounted it to the wall inside the unit enabling smooth airflow on the return duct. My airflow was dramatically increased from each duct and the simple design to move the return air from the far side back through the sound deadening material is a simple but brilliant approach. I would highly recommend this to anyone who wants to reduce the noise level in their coach. The upfront preparation is the most important part, so take your time and tape everything good. You will be satisfied with the results.

    The best decision ever. I installed on both A/C’s. Not only has the noise decreased, but the cold air is now coming out of all vents throughout the RV and is so much more comfortable. You can’t go wrong purchasing this product as it’s worth every Penny!!!

      Thank you Jay for your loyalty.

  52. Loretta Harvey (verified owner)

    Omgoodness this AC silencer is the best. My husband hooked it up and it is so quiet. I was very skeptical but I’m so happy that we bought it. The only thing negative thing I can say is, I wish we would’ve bought it sooner. Thank you very much.

  53. Edward Lawrence (verified owner)

    The silencer does an amazing job, it makes about as much noise as your regular residential air handler. My only gripe is that you lose the quick access to your filter that the dometic intake had. I currently have my RV parked on my property and my kids track in a lot of dirt which inevitably gets sucked into the vent. Now that i need to remove 4 screws to gain access to the filter, I’m worried about the screws stripping or the plastic housing cracking. Other than that, it works well and would definitely recommend it.

  54. Hawkins Williams (verified owner)

    Great product! Reduced my AC noise from ~60 dB to <55 dB which made a huge difference!

  55. Lawre3nce J. (verified owner)

    Excellent product. Low hassle install and cuts down noises to acceptable levels

  56. Carl Valcke (verified owner)

    Very easy to install and nice product!

  57. Lee (verified owner)

    Had one on my old rv and one of the first things I did to my new rv also. Every camper should have one,. Makes the noise level bearable and able to watch the TV without having it turned all the way up. AC works better also because it actually forces air out of the vents now

    Install was easy , I had to trim off wood where my slide comes in because it would have hit the bigger ac cover , have not used the unit yet , but turned on ac and sounds much quieter

  61. Brian C. (verified owner)

    Fits perfectly and works great

  62. Tracy E. (verified owner)

    I was skeptical that this would work and for the price almost didn’t buy but I am so glad I did! Y’all this works, our main ac was right above where we sit and come summertime (Texas) we are yelling and even installed a better soundbar for tv so we could hear the TV! Not only did it drop 5 decibels(does not seem like a lot,but it is so much quieter) but we can actually feel the air coming out of vents on low while sitting in recliners, instead of high and it actually cools our upper bedroom (5th wheel) with out running the ac in bedroom! Amazing product, try it you won’t be disappointed and they have a 30 day return-not that you will need it!

    As a HVAC expert, licensed in 3 states and 38 years commercial & industrial HVAC experience I was sceptical on the performance of this product. Well…I was shocked how quiet our systems are after installing the RV Silencer. Great product!

  71. Linda Goodwin (verified owner)

    Very satisfied! Have recommended it to fellow campers.

  72. Bert (verified owner)

    Silencer made a significant reduction / improvement in noise – with the silencer we can now watch TV in the RV, prior to the silencer, with the air conditioner on, it was just too noisy / annoying.
    Silencer looks good, blends in well with ceiling..
    Sorry no before or after decibel / noise level readings taken.

    • Darrell Abts (store manager)

      Thank you Bert for giving us a try. enjoy

  73. Harvey Jones (verified owner)

    Easy to install

  74. Larry B. (verified owner)

    It definitely reduced the noise level marginally, but it did distributed the air through the ductwork more efficiently.

  75. Robert B. (verified owner)

    Very easy install (about 20 minutes). The AC noise definitely reduced. A benefit not mentioned much is the AC efficiency when the vent in the AC grill is disabled. I believe some of the cold air was just going out the air return when the vent was closed but with the silencer installed the vent is disabled and all the cold air goes through the AC vents. My AC unit runs less and for shorter periods.

  76. John Payne (verified owner)

    Reduced AC noise considerably

    I was a little hesitant at first to buy this not knowing much about it or how it works, after calling and speaking with a lady about the product and how it works/functions I decided to purchase it, the shipping was super fast but just got around to install it and I gotta say it does what they say it does, she said over the phone somewhere around 50-70% quieter and she was absolutely correct my A/C is much quieter and pushes more air out the ceiling vents than ever before. If you are hesitant like I was to purchase this just do it and I’m 100% you won’t regret it!!!

    Your product is well built and has reduced the sound well. I am enclosing a photo of before with old AC cover. You will see the problem I encountered. I failed to take an after picture. I have a 1/8 to 3/16 gap on both sides and used door/window foam strips to fill in. The corners, front and back sides are flush to ceiling. I’m sure you have not seen this. Your product does as advertised so I appreciate that. Any suggestions. Thanks.

      Hello, You can cut the ceiling panel T-Strip trim off so it will not be under the Silencer kit.

  104. Brian Hinrichs (verified owner)

    Only thing I would say is to provide more of the tape and tell customers to tape up the inside around the vent inlets and around the divider between the intake and output. There is so much air loss around those areas. This device coupled with the RV Air Flow Systems my A/C is so quiet. I’m running 61db at the ceiling next to the unit and 54db directly below approximately 4 feet under.

      Hello Brian, we do provide 8′ of foil tape in the kits. Yes if you have a lot of repair work to do in the ceiling you may have to provide yourself more foil tape. We do have extra Aluminum Foil tape PT820AL available when ordering. Thank you for your feedback.

  137. Patricia B. (verified owner)

    I’ve been using it for a couple days now. So far, I’m really happy with the A/C Silencer for my Dometic RV unit. Easy install, I did it myself. Not only is the unit much quieter, but the cool air push through the ducts is more prominent. It seems to cool the camper faster, but that’s probably because I’m not constantly turning it off due to the noise.

  138. Patricia Sheets (verified owner)

    Noise decrease was not as good as I had hoped but it works okay. Looks much better than the replaced unit and totally feel the filter will be much better. Being in it on a hot day will be the tell tale.

    had one on rear air conditioner, then installed a front air conditioner and added one to it

  143. John K. (verified owner)

    I am not rating price here, I am rating value.
    I installed the a/c silencer on a new 2022 GE 15,000 btu with heat pump single ducted unit.
    Installation was easy and everything fit perfectly, very good instructions included with the package, I had a roll of wider metal tape which I used to cover the larger cold air opening
    Appearance is very nice, the cover looks like it belongs and no the word WackO is not displayed although it would be a fun conversation point. We have a 7′ celling so no problem with he thicker cover.
    Performance was well worth the investment making this a high value addition.
    I did not measure the db level as I believe objectionable noise frequency is as important as volume. Before installation the noise from our unit, with the high flow vent closed, was objectionable even on low fan. Running with the high flow vent open was just too noisy so we will not miss this feature. After installation the noise was much less objectionable in either low or high fan mode. Much easier to talk in a normal voice and have the tv volume at a normal level. To quantify I would say 40% improvement in objectionable noise based on listening by both my wife and myself.
    The air flow through the vents seemed to improve a small amount by feel. I have no way to quantify the result so I will guess 10% based on feel.
    The filter is a potential improvement over the bird catcher that comes with the typical a/c unit but I have no way to quantify the benefit. The filter can not be checked unless you remove the cover and I do not know how often it will have to be cleaned. So I will include this with my check often maintenance list until I have more experience.

    Immediately upon installation, which was easily completed, there was a noticeable increase in cool air output and a considerable decrease in noise! We are well pleased and sad we didn’t purchase the silencer sooner!

  145. Phi Nguyen (verified owner)

    This one is a must for ducted A/C. There is significant dB reduction but that is not the whole story. The sound is much more mute and low that practically almost on par with office noise. Which to me is a clear winner. Fact is those A/C companies should have paid Wacko to implement this design to their A/C units.

    I can actually have a conversation without having to yell when the AC is running.

  154. James D. (verified owner)

    Works fairly well, but it is over-priced in my opinion. The lack of convenient filter access is a negative. One must unscrew and remove the unit to gain access. For the cost of this unit, it should have hinged access, or perhaps a slide-out filter tray.

  155. Shawn (verified owner)

    We can hear over the AC running now. Sounds like a significant reduction in noise. Using a decibel meter there is very little change with and without it installed. But you can easily hear now, I can stand under it now and make a phone call.

    Worth every penny

    I thought it was a little pricey to begin with, but now that it’s installed and I’ve heard and felt the difference it makes, I think it’s value priced. I now have cold air coming into the bedroom of our 36 ft. 5th wheel. That makes it a value at twice the price.

    I was surprised at how effective this product actually is to reduce the overall noise that the overhead air conditioner units in our RV make. Great product!

    Installed and tested, and benchmarked with a noise meter. The silencer does a measureable improvement in AC noise – now – most of the noise you can hear from the bedroom is just airflow noise in the ductwork. Satisfied, nice design.

    Wow it’s a lot quieter in there now.

  171. Anonymous (verified owner)

    It installed just like they showed in there video. It took me about 30 minutes. It is way quieter in our camper now and it increased the air flow a lot !! Very happy I got it !! Wasn’t excited about the price at first but I think it’s well worth it to me.

    The A/C covers are great. We just recently had a Missouri Coachmen Owners rally this past weekend and we were telling everyone how well they worked. A lot of interest.

  173. Robert C. (verified owner)

    Had one in my last camper, had to get one for the new one asap. Works as described, it made my GE AC quieter on high than it was before on low. Dropped 6 db, 62 down to 56 on high, and 5 db on low, 58 down to 53 according to the phone app, which makes a huge difference. Measured from same spot with all doors and windows closed and phone in exactly the same orientation, before numbers were with the quick dump closed, it was way louder with it open. Seems a little pricey at first, but it’s not something that is going wear out, so it will keep me sleeping like a baby years to come

    The silencer does indeed reduce the air noise from the unit. The baffle idea works well and more air is directed to the ducts in our Ekko. The compressor noise is still there, of course, but it has a much lower frequency content. I only notice it it in bed, not in the rest of the coach. Install was relatively easy with only one or two detours. It’s a great product and good investment.

  177. Anthony (verified owner)

    The product works great, but I don’t like that using it with a GE RV A/C requires drilling through metal. That seems like it could have been avoided with a very slight change to the design of the filter. Also, it delayed installation by over a week since I had to buy a drill and bits which I didn’t have (I’m a full-time RVer, I had an impact driver but it wasn’t strong enough for drilling metal) and didn’t know I was going to need.

    • Darrell Abts (store manager)

      Hello Anthony, With feedback from customers we have updated the product to fit GE without having to drill holes,

  178. James (verified owner)

    First impression: for the part that you are getting this thing is pretty expensive, BUT, holy cow does it work. Just as a guess, the AC is probably 70% quieter now. Most importantly though, the majority of sound eliminated was higher frequency. The noise of the AC went from being an irritating whoosh to a dull hum. It’s much easier to hear the TV, talk on the phone, etc. For the performance, it’s definitely worth the price. AC is a Dometic Brisk Air II.

  179. James Koshute (verified owner)

    Dometic works great!

  180. Gary (verified owner)

    you have to decide if its worth the $, for us the answer is yes, our dog doesn’t run and hide every time the a/c comes on, we can hear the tv etc. , yes i’d do it again

      Yes, the A/C noise can affect pets. Glad we are able to help. Thank you,

    My wife works from home (currently our RV) and is on conference call most of the day. We used to have to turn our A/C off for her to be able to have these calls. What a difference this makes! We can also turn our TV down now and still be able to hear it while the A/C is running…couldn’t be happier!

    We have the Dometic and the install was pretty much read and go. No need for You tube video. I had already seen them before buying. After the install I turned the A/C on and it was a game changer. It was quieter and stronger coming out of every vent in the trailer. Should’ve done this a couple years ago. Thank you

    Probably a more pronounced reduction for RVs without 5″ of insulation in the roof. Achieved about 1.5 dB reduction. Still worth the effort and expense, though. Great design!

  204. Andrew E. (verified owner)

    The install was easy and it definitely makes a difference in the sound level … can watch tv without changing the volume now. You don’t have the vent in the unit for direct cooling any more, which is nice when it’s really hot, but the quiet level is worth the trade off.

  205. Richard D. (verified owner)

    I highly recommend this product to reduce the noise of the rv ac unit. I purchased one several months ago just to see if it worked as advertised. I have to say that it exceeded my expectations and I purchased another DA 100 for the rear unit. The installation was fairly simple and all the parts fit perfectly.

  210. Dave J. (verified owner)

    We just installed the Wacko RV A/C Silencer on our Dometic unit in our Surveyor Travel Trailer. Yes, it is worth the money! Not only is it quieter (even with the fan on high), but with the included foil tape, we sealed off the flimsy foam Dometic factory air baffles that was basically letting what should have been output air get sucked back through the intake…so now our airflow volume is even better throughout the camper and the grill provides a nice updated look at well!

  211. mark massingham

    Easy install, but massive difference. I measured around 78 decibels about 10 ft away pre fitment and around 65 after. You can now hold a conversation. Will now order 2nd one for the bedroom

  212. Rod Beeche (verified owner)

    I was apprehensive before I order the RV A/C Silencer but after reading the users reviews I made my decision on them and I couldn’t be happier that I did.
    The installation was easy and it took me about 1 hour from start to finish. I have the Dometic unit in my coach and the results are amazing, when I tried it I was so happy with the end results the unit is much more quieter and my wife thinks the results are incredible.
    I will be ordering a second one for the rear A/C unit. Thank you Wacko Products and for great American ingenuity.

  213. Jeff Franck (verified owner)

    I don’t often leave reviews, but I wanted to take a minute to thank you for your prompt service and simple product design. I experienced an impressive reduction in noise of over 10 decibels, from the low 70s to the low 60s. Although I would have enjoyed paying less for your well designed solution, the cost was modest when compared to replacing the entire unit. Your instructions were easy to follow and the supplemental video was helpful as well. I appreciated the quality of materials and your attention to details, like more than enough tape to do the job. Well done.

  214. Ray Colbert (verified owner)

    Installed today in my motorhome. My wife helped me. It took us about an hour start to finish. Reduced the jet airplane noise by about 35-40 percent.
    Instructions are simple and tools needed are minimal. An electric screw gun is very helpful.

  215. Chance Kolschefsky (verified owner)

    This thing is awesome!!! Glad I didn’t wait after finding out about them! Surprised how much quieter it makes the AC.

  216. Brian M. Polka (verified owner)

    I wasn’t sure at first, but after installing this product you can tell a very noticeable decrease in the sound of the Dometic unit. Not only significantly quieter, but also it seems more efficient. Installation was less than 30 minutes with much of the time just trying to get the backing off the foil tape. The loss of the “cold air dump” feature is not a big deal to me as we rarely used that feature so all in all, very happy with the purchase and well worth the investment.

    Note: Have a 2020 Keystone Passport 3400QD and there is an issue in that height of the RV A/C Silencer coming from the ceiling is greater than the stock unit which makes the cabinet about the TV unable to fully open. If the unit was quarter of an inch shorter it would be fine, but unfortunately it just barley hits the corner. Not going to give a negative mark to the product because that’s not their fault, but just something to keep mindful of if you have a cabinet door that opens under the stock Dometic A/C unit.

  217. Jay Peabody (verified owner)

    Very happy with Dometic RV A/C Silencer!
    Installed last weekend in about 30 minutes. The noise is cut down by over half….

    I have to say I was skeptical about this product when I first saw it. I purchased one to check it out and see if it works, well, I was surprised! It works great and we even noticed the difference in flow through the ductwork. Looks like I will be ordering a second one!

  221. DOUG A MILLER (verified owner)

    Purchased this about a year ago. Installed in less than an hour (after waiting for Covid lockdowns to end in our area). Used this throughout the summer and fall camping season, including a 3 week trip to the southwest (temps over 100-110 for 2 weeks in that period). My wife had originally thought this was a dumb purchase – changed her mind quickly after realizing the 10 dB or so drop in sound. At the end of our trip, she was touting the benefits of this to other campers. Hope you got some sales!

  222. Charles A. Barnes (verified owner)

    Just installed this wonderful system. Good engineering, quality materials and easy to understand instructions. The best part is it WORKS. You will be amazed how much quieter you AC/heatpump will be!

    Installed on 2020 Wolf Pack. System much quieter. Installed in 35 minutes. Very easy. Love it.

  224. Christian Odell

    I installed the silencer on our 2016 Salem 30KQBSS and there is a big difference in the main living area. Sitting at the dinette you can tell it is much quieter. Using a free app on my IPhone it showed 6-7 Db quieter than before the installation. I am very glad we installed the silencer we always complained how noisy the A/C was in the main living area. It also made a difference in the noise level in the master bedroom and the bunkroom.

  225. Kristofer Beatty (verified owner)

    Installed my DA100 RV AC Silencer yesterday evening in our 2021 Coachmen Leprechaun 319mb and O.M.G. what an immediate difference. The noise from the AC was cut in half and the cool air actually blow out of the ceiling ducts so well it made a hanging “Welcome” flag move in the air movement. The other problem the silencer corrected is with the AC unit in “AUTO”, the blower in our AC unit used to turn off while the compressor kept running, then a couple of seconds later, the blower would start back up again, only to stop a few seconds later, and so on, and so on. That stopped immediately. I was about to replace our current AC unit and add one to the bedroom, but now I am going hold off on that project.

  226. Mark Peterson

    I had higher hopes for this product based on reviews so I bought one. $200 later – here’s my actual owners review. I have a 2018 Grand Design Imagine, around 27’ with one slide and the AC right in the middle of the living area – and right in front of the TV. With a garden variety db app on my iPhone 7 and the iPhone on the couch -with the system off I recorded around 45-46db ambient noise inside the camper. With the original Dometic shroud and the blow-through vent OPEN I recorded about 70-71db. With the blow through CLOSED around 67-68db. Now with the Wacko installed – 62-63db. Quieter? Yes. $200 worth? No, not really. It does quiet the AC down but I don’t know if the juice is worth the squeeze as they say. $100? Sure. But you still have to turn the TV up and down between AC cycles and you still have to elevate your voice to talk someone 5′ away from you. On the plus side – it was easy to install, pretty nice quality parts and easy instructions,.

  227. Elizabeth Parton (verified owner)

    Cannot BELIEVE THE Change! I bought this just hoping for some difference. I am a 60+ female and installed myself. Several weeks later I was having a staycation in my yard and turned on the air and was watching tv. OH MY! I could not believe the change…I did not have to turn the volume up and down! I am so glad I got this! THANK YOU!

  228. Kenneth Harris (verified owner)

    What a drastic change in the noise level. Maybe my best camper accessory purchase to date. Really easy install and I’m super pleased.

  229. William Buffa (verified owner)

    Saw it in trailer life magazine and bought it over the winter. With the covid scare I only got to try it out this weekend, I was impressed! I could watch TV and carry on a conversation without the a/c drowning me out, and it was easy to install. I would definitely recommend this product!

  230. Braden Shoupe (verified owner)

    Installed this adapter in about 15 minutes prior to our recent outing. Not only a tremendous drop in noise, but the airflow through the ducts improved so much that the entire trailer stayed cool in 95 degree plus heat.
    I should have done this sooner.

  231. Roger S Buhovecky (verified owner)

    I originally gave this cover a 3 star review as I only gained about 3-4db. However Darrell from WackO contacted me and said I must have the cover installed wrong. He was correct as I had put the cover on 180 degrees out of position. I had put the louvers over the filter which was incorrect. Prior to installing the cover I took a reading under the unit appx 2.5 ft away from the cover and my meter varied from 51-52db. After I installed it correctly the meter read 46-47db. This was a 5-6 db gain. He was very responsive to help me correct my mistake.

  232. Robert Mitchell

    We bought the RV A/C Silencer a year ago and have been using our RV full-time ever since installation. What a difference! It is currently in the 90s every day in Texas and the A/C runs almost all day long. With the old cover, it was deafening in the living area of the RV. With the RC A/C Silencer, it is actually livable. Great product. Easy to install. Lives up to its name.

  233. Luke (verified owner)

    Does what it says it will do. Easy to install in a 31-ft Puma. I took before/after readings using the Apple Watch decibel meter. I measured in two places: directly below the unit at 48” from the floor, and at the edge of the dinette table approximately 50” laterally from the unit. Before, with the air dump closed on the stock unit, I measured 65dB under the unit and 58 at the table. After installation, I measured 57dB under the unit and 52 at the table. As others have noted here, 6-8dB is a substantial reduction in noise. Just to be sure the taping of the dump vent was not causing all or most of the sound reduction, I also measured the sound with the vent taped before I installed the cover. Readings were 65dB directly under the unit, and 59 at the table. This silencer works.

  234. Daniel Herod (verified owner)

    A real improvement. When the package arrived, I thought I’d probably wasted my money. I had no way to test it because we don’t have a 30 amp outlet at our house. All I had to go on was reviews from other customers. This weekend we finally went camping and both my wife and I were very pleasantly surprised at how much quieter it makes the A/C. To be sure, the A/C is still loud, but we can actually watch TV now. Before this silencer, we literally could not turn up our TV loud enough to hear it over the A/C. 2018 Keystone Cougar. This product is truly worth the price, at least in our book. The A/C noise went from outrageous to tolerable.

  235. Donald Ryan (verified owner)

    Received my A/C Silencer a couple months ago and finally got it installed today. Easy install, looks good and really cuts down the noise. I was able to hear the stereo without cranking it up to “11”. A vast improvement. Well worth the $ and time.

  236. Rick Martin (verified owner)

    First read about this in Trailer Life months ago. The reviews were mostly positive. Well last weekend we got our Jayco Whitehawk out of winter storage, ordered the silencer and installed this week (easy install ). BIG difference ! And as what other reviewers have stated , you can carry on a normal voice conversation and not have to crank up the TV volume to hear. Money well spent…

  237. Bill Bateman (verified owner)

    We use to have the TV volumn nearly wide open to be able to hear it above the AC. Installed the silencer, turned the AC on, & instatly amazed at how quiet in was. TV is now turned down low. It also seems like the AC puts out better now. It seems cooler throughtout our 5th wheel. We highly recommend it.

  238. Kevin J. Tovornik (verified owner)

    Just installed the silencer and I wish I would have taken sound level readings and air flow measurements.
    This product is absolutely incredible!
    I wouldn’t be surprised if the noise level dropped by 70% or more and air flow increased by a third. It has got to be right up there close to the newest models with the whisper quiet air systems.
    Hell of a product guy’s !!!

    Purchased Dometic DA100 model for both my 5th wheel and my motorhome. They arrived well packaged and on time ( fast ). The covers are well made of good solid material. Directions were good. All necessary installation items were included. Everything fit perfect. The work is overhead, and I am old, but still installed both units in about 30 minutes. The noise was reduced by about 50%, which will help save my sanity while in the rig , and perhaps save my marriage. The A/C noise was driving us both out of our skull.

    I read about this kit in Trailer Life magazine. I have a Carbon toy hauler by Keystone. The 2 A/C vents in the garage barely put out any air. We use the garage as living space once unloaded. This was not comfortable. The unit in the main living area was loud enough that you had to turning up the tv or radio to hear it, then down when the air shut off. I purchased this kit and installed it myself. Very simple install. Easy to follow instructions, and man what a difference! We have A/C in the garage, we can watch tv normally, AND, the vents in the bedroom also have more air, so probably won’t need to run that unit at night. Very happy with my purchase, from order to install. All went well! Thank You!

  243. Kevin Shults (verified owner)

    I read about your product on the Grand Design Owners forum. I must admit that I was skeptical regarding the products ability to reduce our Dometic ACs operational volume.

    I could not be more pleased. Your product has reduced the system’s noise level in half. We no longer need to turn up the TV volume to compensate when the AC comes on.

  249. Dan McMillan (verified owner)

    Great product and what a difference. Decibel levels prior to installation were 71db on high fan, 66db on low. After installation high fan dropped to 56db and low to 54db. The compressor was not running. I assume it will be a little louder with the compressor running. I’ll get that when it warms up. This was on a 2020 Cougar with a Dometic unit.

    Very easy to install in my 2010 Concord Class C especially with the how to install video. Prior to installation, my decibel reading was between 70 and 71. After installation my decibel reading was 60 which is the normal reading during conversations. I won’t know about the effectiveness of the cooling aspect until this summer-2020.

    Wow what a difference this makes in the front bedroom of our 5th wheel! I wanted to reduce the noise from this unit, and found this silencer in Trailer Life magazine. I looked at the reviews and a few videos and thought why not give it a try. I could not be more pleased with the operation of this item. It is truly does what it was designed to do – reduce the noise. We can actually lay in bed and listen to the TV while the unit is running now. Thanks for a great product! Do yourself a favor and invest in one of these!

    We purchased two of them for our 2019 Torque T322 and it is amazing how much quieter the units are now. The supply air flow increase an estimated 10-15%. (I did re-tape the unit openings in the ceiling plenum). My rv buddies will be purchasing them after coming over to check out the difference in noise and air flow. Great product!

    I’ve now purchased three of these for two different RV. I absolutely love them. It’s hard to believe how much quitter the AC is, at least half if not quieter. You do loose the large air dump but this has not been an issue for us. Also, I made a point of purchasing a roll of Aluminum duct tape and re-taped the inside of our AC ducts especially between the intake and exhaust sides. I also zip tied and managed all the cabling to reduce turbulence. Darrell, the owner is a great guy. I had an issue with my install where I spun one of the cover screws. No questions asked, Darrell replaced the unit.

    I saw this product in Trailer Life magazine and immediately ordered a unit for my Domestic A/C. Standing directly under the original dump cover I got a reading of 72db. After installation of the new silencer ( 15 min. job) I got a readout of 63db ! ! That’s nearly half the original noise. Amazing! Quality of the molded plastic components is superb. I highly recommend this product.

    very efficient and does what it claims to do. Easy installation as well.

    Works just as advertised. Be careful to purchase the correct kit for the correct AC unit. We have a Coleman Trailer WITH a Dometic AC…. Sent the erroneous kit back for a refund. Second was perfect. Installed wigth a power driver in about 15 minutes, with most of the time being used to tape shut the large vent and other smaller openings. all the pieces fit as they were supposed to, and the sound difference is AMAZ
    ING in a 23-foot trailer, to say the least. This will be a HUGE help next summer when we are sleeping on those hot nights!

    I originally installed this product incorrectly. Darrell was very helpful in helping me discover I installed the black cover up side down which caused the screw holes on the white cover housing to not line up. Needless to say it works perfect now and my Dometic 15K BTU AC is much quieter. Highly recommended, great customer support.

  260. Joe Goodman

    Easy to install, works amazing quieting down those obnoxious AC units! Worth every penny!

  261. John Gentzvein

    I purchased two for my Palazzo diesel pusher. The air conditioners were disturbingly noisy. I heard about these silencers from an acquaintance who said they work. The installation was straight forward, fit and finish outstanding. The difference is amazing, a substantial muting of the blowing and drone noice. I’m truly impressed with the perfect fit. I’ll certainly recommend this to all in my circle.

    Installed my silencer on one of AC units in coach. What a difference. Great product. Will be ordering for the other AC units.
    Thank you for creating this.

  263. Thomas Cannon (verified owner)

    After reading initial reviews I ordered two of these, and they are fantastic. Called the company with a question and the owner answered the phone and we had a great talk about why he created this product and how it works. Since installing them we have traveled across the country from Oregon to Virginia, where today it was 101 and both AC units have been running all day… and we can carry on a normal conversation.

    These are truly one of the best modifications we have made to our RV in five years of full time travel. Don’t hesitate, get one or two now!

  264. Michael Traxler (verified owner)

    Installed as soon as I received it. Easy install. Works like a champ! Tames the A/C noise so good, we no longer have to crank the volume on the TV when it kicks on! Bravo Wacko! Highly recommend this product.

  265. Ken (verified owner)

    Awesome! I do not have a DB meter, but when I installed this silencer on my Dometic unit, it cut the noise level to less than half its previous level. It has more air circulation now also. I had my doubts, $200 for a couple pieces of plastic and some insulation. You will not regret your investment! It does everything they claim, and more.

  266. Gary Way (verified owner)

    Installed this yesterday in my Coach. First off it looks much nicer than the Dometic Dump grill and the filter is amazing! Turned on the A/C and WOW I was amazed at the difference. It is much quieter now. The vents blow like they were supposed to and cold air blows freely. This product is amazing and I would recommend it highly. Thanks Wacko for such a great ideal.

  267. Arnie

    Have had the silencer for about a month now and it does quite the unit. In my opinion, I think we have gotten about a 30% – 40% reduction in noise. At least we can have a conversation or watch TV with the unit running. We have a second a/c unit in the bedroom and have not installed a silencer there as it is a good reminder of how loud the main salon’s unit was. Dometic a/c is the loudest I have ever heard. I think it is well worth the money and easy to install.

    I rarely write reviews on products, but this was one of the best purchases I have ever made for my motorhome. My Dometic A/C was so loud I would have to constantly turn the tv up and down. I installed the unit last week before the FMCA rally in Lakeland Florida. I am absolutely amazed at the difference! I can barely hear my A/C running now. For four days I never had to change the volume on my tv. Matter of fact, occasionally I was not sure if the a/c was even running. I’m going to order another for the bedroom. Fantastic product.

  269. Craig Olthoff (verified owner)

    I ordered a unit after reading about it in the FMCA magazine. I put the silencer in the living room area of our RV. I would say the noise lessened by at least half. I have since ordered a unit for the bedroom! Maybe now I will be able to hear the tv! I would definitely recommend the silencer.

  270. David Hoffman

    I bought one of these at the Forest River Owners Group (FROG) Rally last year. I bought the last one after someone had second thoughts. I immediately could hear a significant drop in the noise level after I installed the new cover. By no means do I claim that it makes the AC totally quiet, you can usually hear it when a home AC is running too. However, the noise level is noticeably lower. My motor home AC unit is a heat pump so I have enjoyed the quiet in both summer and winter operations. I personally recommend this product, you won’t regret it.

Q & A

I have a Dometic Penguin on a 2006 Airstream, the iconic low profile model. I converted it from a ductless manual operation on unit to a ductless wall thermostat operation. Would I be able to use your silencer on my model now that controls are not on unit? Rodney Winkler asked on December 16, 2023

Great question Rodney, The Silencer kit will only work on units with a ducted system with a wall thermostat. So unfortunately the Silencer kit will not work for your application because it is non ducted unit.

the air only comes ou of the shold insde will this work mike asked on September 10, 2023

The Silencer kit only works on ducted units with a wall thermostat. If the air only goes in and out of the A/C itself then you have a non duct unit.

Does this work with the Little Guy Max with the GE brand AC unit on the roof? Chris M. asked on August 12, 2023

Please send me a picture of the inside ceiling assembly to [email protected]. Verify that it is a ducted unit. Make sure the silencer will not interfere with slides, doors, and appliances as the silencer is 17x17x 2.25″
Thank you

Does this help to get better flow to the back of the rv? Kandie Howard asked on May 7, 2023

The kits will allow up to 40% more airflow to the AC unit. Depending on your duct work in the ceiling yes you will see more flow.
