    After reading all the positive reviews I decided to order a kit for the Coleman a/c unit in our 2019 KZ 301BHSE travel trailer. Ordered on a Sunday evening. Received the kit Wednesday afternoon! Instructions are straightforward and easy to follow. The new kit fit perfect aligning the holes in the kit to the holes in the metal frame mounted in the ceiling. And it did literally take only about 15 to 20 minutes to install. The filter is better than the ones that come with the a/c from the factory. The new kit also seals to the roof unit better eliminating air leaks around the ceiling assembly that were present with the factory unit. We hardly ever used the air dump feature for the living room on the factory one so won’t miss it. I have to say the main unit is more quiet but also the amount of air coming out of the vents in the front bedroom and rear bunkhouse is noticeably increased. Also compared to the factory assembly this unit has a larger vent opening for air going in to the a/c to be cooled. That might account for the increased airflow to the ducted vents. I agree the kit is pricey but I can see our a/c being more efficient come this summer.

    Wow! lessened the noise by 8 DB. Easy install. Every hole lined up to my Coleman Mach unit. Plus it looks better than the square grate that was on there.

    I installed this Silencer on my Coleman Mach and I love it. It does a great job forcing more air thru the interior vents and it definitely quiets down the sound. I can now watch TV in the living area and Im even a little hard of hearing. Great product!!

    The RV A/C Silencer does what it’s name implies. Our 35 ft. KZ toy hauler has one big ducted air conditioner in the main salon and was noisy. The kit was complete, installation easily accomplished with a Phillips screwdriver and results in a quieter AC operations. Now we do not have to turn up the TV to hear over the AC roar. Highly recommend it.

  5. Jim Y (verified owner)

    The A/C Silencer was easy to install with no problems and the finished product was significantly quieter than before. I would highly recommend this product.

  6. Don Tardiff

    Your RV Silencer is a game changer. I just installed it in 15min in my 2019 Aspen Trail by Dutchman and we can actually stand in the kitchen area and have a conversation without screaming at each other. I would and will highly recommend youR product to family and friends. Why this isn’t installed at the factory is beyond me, if I was a manufacturer I would contract with you to provide these at my facility.
    Thank you,
    Don Tardiff

    I recieved it today and installed it. I can’t believe how quit it is. Also there is more air flow when ac is running.

  8. Lori McAfee (verified owner)

    I am very happy with both the personal service from Darrell, answers to my questions, and the product performance. It was easy, very fast, and immediately helpful in reducing the annoyance of the AC.

    Thanks again Darrell!

    Just added this to our 2019 Entegra Odyssey 26D Class C. It works for us and certainly lowered the noise level to where we can converse more easily and watch TV without turning up the volume as loudly as we used to do.

    And I forgot to mention the filter is aces! It is actually going to filter the air!

    Gents, Apologies for a long delayed review of your WACKO grill. Full disclosure! This is a 2013/14 View Profile 24G with a Coleman Mach 8 ducted unit installed near the rear bedroom. The early Mach 8s’ were as loud as an F-4 Phantom in re-heat on take off. So loud inside and out. Yes you could hear it running from 300′ away. Inside it was like a saw mill. Annoyingly loud in the rear of the coach. As a result, i made several ‘McGuyvers’ to reduce the exterior and interior noise levels: vibration damping the bonnet using foil faced butyl roofing tape; replacing the 6 blade turbine fan with an improved three blade ‘elf ear’ version; building a ‘turning vane’ to smooth the air flow in side the intake; adding a Perfect Casita Mach 8 “hush” kit that reduces the condenser fan’s speed about 2/3 to 1/2 and the low restriction grill on the bonnet. So it’s not a stock out of the box unit.

    I bought a CA-200 back in June or July 2019. I was overtaken by events and weather and I didn’t install it until September 2019 when I could do some sound measurements on a calm day. It was probably over done with 30 measurements and 90 data points. The results appeared to show that the grill does reduce sound levels inside the RV. They are reduced more as you approach the intake grill. That probably means that the sounds are not transmitted to other parts of the RV. That’s good! Subjectively, sitting in the driveway it was quieter. The first impression is that the roaring and mechanical noise of the unit is reduced. I wasn’t able to test it on the ‘road’ until about November 2019. The same positive results. The best comment I can make is that even with my McGuyver mods (as quiet as it was) there was a constant background roaring sound toward the rear of the coach. Sometimes I didn’t want to turn the unit on as it was annoying. After installing the WACKO and ‘putting some miles on it’ I don’t give it a second thought. Just turn on the AC or heat and enjoy yourself. About the only sounds now are from the ducted vents. Going front to back of the coach you hardly notice that the unit is actually running except for the low noise from the vents.

    The kit is of very high quality. The fit and finish is perfect. Instructions are clear and easy to follow. There was a very minor screw alignment problem on my unit with the ‘baffle’ installation. I suspect that there was a change in Coleman’s design or WBGO did a hamfisted install and got the unit’s base slightly sprung out of alignment. Quick work with a drill and no problems.

    Good job Lads! Good JOB!!!

    Very easy installation and made a significant difference in the noise level. I will be ordering another one for the other air conditioner in our 5th wheel. I definitely recommended this product.

  13. Gary Renschler

    Cross reference guide would be helpful. Have a Jayco Eagle

    • Darrell Abts

      A Reference guide would not be accurate as RV manufacturers can switch A/C brands anytime with out notice. Also it is common to replace a A/C unit with a different brand. If you are not sure of what you have just send me a picture of the inside ceiling assembly of your A/C. to [email protected] . Thanks

    As most of the other reviews stated, I bought one to test it and immediately placed my order for two more to complete my toy hauler. I can’t speak for increased airflow thru the ductwork but it makes complete sense, but I can easily attest to the significantly reduced noise level. Also the kit design is perfect, everything is included that you need and no surprises to install, all you need is a phillips screwdriver and a few minutes to make a significant improvement. Quality is top notch.

    Good product, installation was not difficult. I appreciated the foil tape provided, I used it extensively to patch gaps. I added thumb screws to secure the plastic shroud to facilitate easier cleaning. I bought a second after installing the first.

  16. andrew bereznak (verified owner)

    this product makes a TREMENDOUS difference. i have coleman air conditioners and installed one. your site says there is a 3 – 5 decibel reduction, but i am quite sure it is more than that. i ordered a second one after verifying it would make a difference. i am very happy. my only wish is that when i added my third ac unit i would have taken the time to tie it into the ductwork so i could install a third (instead i took the easy way out and made it ductless).

  17. JAMES SHIREY (verified owner)

    Thank you for developing a needed product that works. We received it and installed it on our main living area ac and immediately noticed the difference in ac sound and also better air flow. Very happy with your product we ordered a second unit for our bedroom a/c . Will order a third unit for the third a/c in the garage of our toy hauler. Bottom line is this product does what it says it does.

    Thank you for shipping so fast. I did get before our trip out. The install was simple and we are very happy. I did wait to write this review because I waited to make sure it solved my air flow issue. IT WORKS. no more frosting up. You are going to do well. Thanks again Bill and Lori
