Testing RV AC Upgrades! (RV AC Silencer / RVAirFlow)

[@bobgil3464]

Between the A/C unit and the occasional Generator noise we thought the only solution was to purchase a soundbar to hear the TV. This will at least solve one of our problems. Great video.

[@stephenbrasure4331]

Last August, we downsized to a 2015 Winnebago Via (25" motorhome on a Sprinter chassis) with a Coleman Mach AC. I installed the Silencer before we even left the RV dealer's lot and I was impressed with the results. We haven't been out too much this year (health issues) but we just returned from a 3 day trip and the weather was hot and humid. In addition to the reduced noise, I'm impressed with how cold the output air is compared to the output of ac units we had on the two travel trailers we've owned over the years. I do think that for the best results, it's important to really seal up all the gaps and leaks with the aluminum taper as part of the installation process. I also think the silencer reduces the frequency range of the AC noise as to my ears, there is a reduction in the higher frequencies. The Silencer is a little pricey, but well worth the investment . If my rig had multiple AC units, I'd install one on each AC unit!

Hi Chad, I’m a retired HVAC contractor and watched this product video. Like you I had already installed the RV Airflow product and was amazed at the difference in air flow and a solution to not blocking more than 50% of the Coleman factory air filters. After watching this video I purchased two covers. While this Silencer product provides some noise reduction it has other shortcomings I am not impressed with. They provide only one foam filter instead of the two from the factory. While it’s not up against the intake louvers, I would argue it has less filter surface area that will require more servicing/cleaning. Such an important task for these units that is made much more difficult by having to unscrew this cover to inspect or clean the air filter. Don’t loose the screws. I look at this product and they could have built in a no tools solution for this task, but they didn’t. I also have a rather large gap between the cover and the ceiling with the cover at the end of the adjustment screw slot, so no more adjustment to put the cover closer. I wouldn’t recommend using this product unless one has already installed RV Airflow because of its restricted air flow that your testing acknowledged. Is it worth it to have a quieter system? Barely. I would replace it in a heartbeat if there was a product that overcame its shortcomings. You’ve had yours for a while. How is servicing the air filter? My product grades: RV Airflow - A+ The RV A/C Silencer - C-

[@tornadotj2059]

I just installed the silencer in my RV over the weekend. The airflow and noise reduction were dramatic. I think the results must vary from RV to RV.

[@racrx7]

I’ve had the Silencer for almost two years now. I didn’t do a DB test, but the lady and I aren’t having to repeat ourselves in conversation lol. It really works that well!! So much so, a fellow RVing friend was amazed at ours and bought one for their big 5th wheel. It’s awesome!

[@davidcooper3871]

Been waiting for this. But, I made my own with a 3D printer. It doubled the air flow.

[@johnshields9601]

We too bought a single Wacko A/C silencer for our bedroom A/C to help us sleep with less noise; however, after installing the first silencer, we bought another Wacko silencer for our front A/C. These units are amazing.

[@djjamminjimlawton6365]

FYI Chad - I am a retired Submarine Sonarman and what is taught to us is that a 3dB increase is roughly twice as loud. I actually taught Submarine noise reduction in New London, CT for 3 years during a shore tour in the early '90s. (Log is correct, not a linear scale - Ambient noise (AIR/Steel) is 10Log where - Submerged (Water) is 20Log.)

[@raiden72]

I am a Wi-Fi engineer and with Wi-Fi DB, I seem to remember that +2DB is double signal, But I could be completely wrong and maybe your 3DB is correct for the doubling!! Not sure how sound equates to Wi-Fi signal DB or if it does or at all

[@ronbernier6377]

Chad thank you for this video. I was wondering if this was feasible and after watching the mods and the results I went out and bought the RV Airflow to add To my RV silencer and this is probably the best combination out there. I just did the A/C mod on My Keystone Cougar and the airflow is amazing!! Thanks again! Camping this week so we will see what happens and if I can turn the camper into a meat locker!!

[@tornadotj2059]

Thank you for making this video, I've wondered about using one or the other, or both. One thing I'd have liked to have seen is if the RV Airflow on its own did anything to lower noise on its own from stock. Over the weekend I installed only the Silencer, and we noticed a dramatic airflow increase over our stock intake - Coleman Mach (not shallow) in a Rockwood Ultra Light. I did not use any measurements like you did, but we tested by hand before and after the install. Also, once I finished the install and turned on the A/C unit, a lot of debris that was in the ducts from the factory came blowing out, so this was a pretty clear indicator the airflow was increased. I did take a significant amount of time ensuring everything was sealed just as Wacko does in their install video, so this almost certainly had some effect on the airflow once completed. Now we can watch TV while the A/C is on, something that was very difficult to do before.

[@ChangingLanes]

The RVAirflow doesn't really reduce noise that much. Glad you got better airflow from the silencer! 👍🏼

[@iknomorethanu]

Just bought 2 RV Airflows using your promo!

[@jbat66]

I installed the RV Airflow a 8 months ago. I installed in a 2007 Monaco Knight Class A. Just a note, they didn't have one for my rig but one close. When I ordered, they got a hold of me, and questioned my measurements, because they didn't line up with the one I ordered. I told them what I have, and they said good to know. We have to do a modification to the product, before we send it so it will fit correctly. I got it and it worked great. So note to others, if they don't have one exactly for your rig AND AC, get a hold of them first, they probably can modify one for you.

[@razmondpush2971]

Thanks again for the invite to your presentation. We sure miss the rest of your family when they are not included in the video's. I too was pleasantly surprised with the outcome as well, duly noted.

[@CFPVideoProductions]

A 100 to one power ratio is 20 dB, etc. Doubling/halving) the actual power is 3 dB (-3 dB). However, our hearing is more logarithmic and people will say that the sound “doubles” in loudness with 8-10 dB increase. Good job. Thanks for your scientific approach to all of your real life evaluations of products. Don

[@NAHWTV]

Audio engineer here. Decibels are indeed weird. 6dB is a doubling of sound pressure. But because our ears have such a wide dynamic range, it is generally thought that we perceive 10dB as a doubling.

[@johnnylightning1491]

Since watching your video, I feel like I could actually take on this job. I realize the results may vary, as they always do! Thanks for your attention to detail. Our AC unit is ducted through the ceiling. The unit can also exit through the AC unit itself. Personally, I prefer going through the duct work, since it is so much quieter.

[@richardburguillos3118]

I think I remember one reviewer stating that there is a change in the pitch of the air flow sound after the silencer and that the pitch / tone is a bit more comfortable adding to the actual dB reduction in sound making it overall feel greater than what the meter is telling you.

[@ChangingLanes]

That may be true and might be why it sounded softer to my brain.. 😊

[@MilSpecTech]

We installed one of the original RV Airflow units in our 2021 Primetime Avenger 27RBS a couple of years ago. Since the single Coleman Mach 20K AC unit is right above the the entertainment center it made watching TV or listening to music strained at best. The noise reduction was dramatic and the A/C unit performed better to boot. Love this product! Nice to see you agree and the product is consistent among various installations. Keep up the great work!!

so you're saying that the airflow by itself also decreased noise? to bad he didn't test it by itself

I got the AC silencer for my dometic ACs in my 397th. I added some sound absorbing mat (for car audio applications) and it knocked the sound down about 3 more dB in addition to what the silencer did by itself. Also, the filter assembly is much better with the AC silencer than the horrible dometic filter setup.

Great video. We have the RvAirflow and love how well it works. A huge plus was how much quieter it runs vs stock. It would be cool to see the dB change of just the RvAirflow over the stock system and compare that to the silencer. Does it quiet just as much? Also maybe a future video idea is a comparison of the RvAirflow vs the DIY airflow hack. The DIYers claim its just as good but only $15 in materials. Imo the RvAirflow looks designed better. Would be cool to see if it's worth the price difference.

[@ChangingLanes]

RVAirflow claims 3dB improvement. We didn't notice a big improvement in sound in our last RV wtih just RVAirFlow... The other thing about the DIY versions is regular styrofoam can hold and allow mold and bacteria to grow. RVAF uses a special kind of high density foam: "The RV Airflow System is manufactured from 3lb Expanded Polystrene (EPS), the highest density available. It is highly durable, temperature and water resistant and prevents bacteria and mold growth. It contains no CFC, HCFC or HFC blowing agents or formaldehyde, is chemically inert so it does not produce methane gas or any contaminating leachates and is 100% recyclable! "

Filtering the decibel reading by frequency is helpful. Certain mid range frequencies are irritating, (opinion only), similar to certain lower frequency hum sounds.

[@donaldlajeunesse1455]

Great video. The rv silencer website says increased air flow. Unless I did not see it correctly your test showed decrease air flow. I wonder if this emulates a blocked duct or can this reduction of air flow have long term effects on these small coleman machs. I think the silence would be golden but good air flow in warm climates like the results of the rv air flow works with the system not against it like the silencer in my opinion. I could be wrong but these are non commercial units designed to function as is to obtain a good service life.

[@tornadotj2059]

I think this varies from RV to RV. I installed just the silencer on my RV over the weekend and airflow is dramatically increased through the ducts.

[@phecksel]

Chad, I hate you!!! LOL. Now I have to order something else for the 5th wheel. One other note, and given your rig and you may already have something similar to easy start. When I added easy start to my TT, I noticed a definite noise level reduction coming off the compressor, even when running. No measurement available, but I could hear a difference. I've installed the RV airflow in the 5th wheel, and it had a noticeable air flow improvement. I'm going to be installing easy start on the main AC in a few weeks, and guess I'm going to order the Silencer too.

Great info. I would be concerned about the silencer causing the unit to have to work a little harder. Long term implications thoughts? You said it redirects the airflow and your silencer data showed that it is truly "choking" the system slightly. Maybe it is a small enough change there will be no additional strain put on the system to cause a shorter life span or other problems. Thanks for the data. Love the channel.

[@ChangingLanes]

I think technically that must be true. But I'm sure the fan motors are designed with a large range as the inflow/outflow parameters can change dramatically just by opening the dump vents, closing AC vents, etc.

@@ChangingLanes But the improvement in the airflow (volume & temperature) may result in less operation time. Base on the airflow out of our duct work, I really don't have a concern.
