UPDATE (July 2021): We've had a few questions on the torque values we mention in the video.
I got them from the RVAirflow document here: cdn.shopify.co...
It cites Coleman manufacturing as the source…
However, looking at www.airxcel.co... it just says, "Proper tension has been achieved for each bolt when any portion of each gasket indicating tab has been pulled down even with the roof. See Figure 4. The upper unit has now been properly installed with optimum gasket compression.”
Our take: Use your best judgment. If the torque value seems too high, revert to the instructions from AirXCel.

Just tape up the dumps !!
170 dollars? For foam?
That's US, try Canadian dollars. Add 30 percent, 15 percent taxes and probably 20 percent customs.
Great video and well presented, but unfortunately @ $175 each it's not for me, I purchased supplies at Lowe's and did both of mine for less than $20
What did you buy at Lowes please
Maybe even put some tape across the back of those high side vents.
Our Jayco North Point has the whisper quit duct system. You don’t have that old school system in the ceiling. I’m sure Gran Design will start incorporating this system into production.
That old system creates air turbulence.
We enjoy your videos😊
Love your videos.
I just installed one in my Grand Design Imagine. The only difference is I used the same foil tape that you used to seal up the box to seal the back of the dump louvers. Now someone can’t make a mistake and open one and as I inspected them I suspect air would bypass through the louvers anyway because they don’t seal very well. Now it is sealed.
You guys really need to check your Freon pressures after installation. When you have more air moving through the evaporator coil you are warming it up. The more heat you add the higher the pressures go up. The units for sure gonna be over charged. Your a/c compressors gonna burn out prematurely. I can’t believe Coleman said it’s ok to do this. They must not care how long there unit lasts. I’ve been a technician for 17 years now. You need to check your pressures
OK...but my Coleman with the RV Airflow is almost though it's third summer and still performs extremely well. Airflow went from 8-9 mph to 18-20mph now. The airflow prior to the install had so many blockages I am surprised it didn't fail due to back pressures in the AC. Runs like it was designed to do now.
Blown away.
Great video. You guys are a hoot!
Thanks for getting us a discount
Thanks for this tips.
YOU ARE SO AWESOME... I'M IN FLORIDA... ITS RIDICULOUSLY HOT.. JUST BOUGHT WHAT IS CALLED A PARK MODEL ..PUMA... THE AC IS A HOT MESS...SO APPRECIATE YOUR VIDEO.. !
I definitely need this! Only two or three of my vents actually blow any type of air between my two AC units. I always have to keep my dump vents open dud to lack of air flowing through my ducts.
Grand Design Cult on full display!!!
Combat Vets Motorcycle Club 👍
Did you notice an increase in noise.
Pretty outrageous price.
Cheaper than a newer bigger unit.
Thank you, just ordered and used your code. Happy Wife Happy Life!
How's this been working after a year? Thank you for the detailed walkthrough and video. Amazingly done.
Still works great! 👍🏼
Third summer with mine. Still getting 18-20mph though the ducts...prior to install it was 8-9
what if you don't have ducks do they have one for them
Not a single dislike
One of the units keeps tripping the breaker...
thanks for the info and what chapter are you with i am with 35-5 out of Michigan
Great Video! Thank You. I'm ordering a few. But where's the discount code? Thanks again 👍
It's in the description.. But, use this like and code CHANGINGLANES at checkout for 15% Off!: changinglanesrv.com/rvairflow
When my ACs are on direct dump they put out a TON of air. When I close the dumps, I don't get much at all out of the vents. I'd be curious to see you compare your ACs direct dump volume to how much you get in total from your vents.
Not sure trailer model is needed but I have a 2020 Keystone 357 Impact Fuzion toyhauler
It must be quieter too?
What's that ladder? Looks lightweight and easy to store.
One thing to remember WHEN YOU TORQUE THE LONG SCREWS BACK DOWN THEY ARE TORQUED TO INCH POUNDS NOT FOOT POUNDS.
My husband and I bought one of these and HOLY CRAP, way more cold air blowing out of our a/c, and it works more efficiently. Our a/c keep freezing up, prior to installing this, because cold air was leaking into the area where the temperature probe sensor thing is up inside the a/c unit. This summer... it never froze once!!! We live in Florida, so a well functioning a/c is a must. We highly recommend this product.
Your Amazon link to the air filters doesn’t work.
I've made that mistake before :) stop the video at 12:20 and look at how he's pushing that razor toward his other hand. Building and drinking beer in the hot sun obviously isn't the best of situations, yet here we are. I was opening a pack of shingles sloppily on a decently slanted roof. Holding the pack with my left hand, keeping from sliding then trying to cut the plastic with my right. Well, I didn't realized I gashed myself until I went to pick up the hammer and it just slipped right out of my hand... turns out I was bleeding pretty good but didn't feel a damn thing :) I learned that day to never cut toward my body, always away. drunk or not :) JSWOA. but I still drink beer and do dumb stuff.
Where can I buy this insert Thanks
Mine freezes alot and comes out in home and I don't get air in back of camper
This is good info...It is 105 in the shade here in Texas and my AC is purring like a kitten... I would like to add what I did to my Mach 3 coleman AC unit that made a night and day difference on my RV.... I stay out at the lake in the summer and live in my RV for 2 or 3 months out at the lake every summer, so I need my AC...I bought some regular o'l pipe foam insulation and put it on all the cold pipes between the Compressor and the condenser, covered the accumulator in 1/4 inch foam padding using 10" wire ties and glued the 1/4 inch foam pad onto the entire outside of my tin condenser box cover using spray adhesive. The water practically trickles out of the condenser now and the air is chill coming out of the AC vents. I also put a corrigated tin cover on a 2" X 2" wood frame with 2"X2"X2" wood spacers, over the AC unit. This creates a 3" air space over the AC unit and it is always in the shade , believe me when I tell you, it makes a big difference. Dont want to go into too much detail right now. Get some 1/4 X 20 4 inch long flat head bolts to screw it all back down... You can PM me for more info if you want.... Dave
where is your ppe?
Have been debating this since before we even bought our rv... now we've had it out twice and I'm definitely doing this on the living area ac. I couldnt get your discount code to work on their site this evening though?
I just tested it and it worked... code is "CHANGINGLANES", and you put it in when checking out.
@@ChangingLanesokay must have been a fluke or something then, I will try it again. Many thanks, love the videos!
I noticed a huge increase in air flow with my rig as soon as I popped those stupid directional circles out of the ceiling. They weren't allowing the maximum amount of air to fall instead they were only letting out a little bit and the rest was going to straight to my bedroom. So I noticed a huge difference just by popping those out
I’m a long time subscriber I watched this video a long time ago I finally bought a RV airflow. You do a wonderful job at explaining the install on all your DYI projects even for someone slow like me 🤣. Thank you for all your help and your tips and information. Safe travels sending you positive energy. From Malibu California 🙏🏼❤️🤙🏼
how do these help vs a whisper quiet system
We only have these.. but, we hear the whisper and these work well together. I believe the whisper is just about noise and not airflow.
For anyone wondering the kits are $170 plus S&H
Is it flammable?
Nice, but super overpriced… I would pay $50 but never 170. I am making my own, already have all the tools in hand
Cool
Fantastic video. Does the discount code still work? $170 per unit x 2 is crazy 😱 but may be worth it
Yes it does! 👍🏼
how's the performance after a full summers use?
170?! That's crazy.
If I have dometic thermostat on the wall to turn AC unit on, does that automatically mean I have dometic AC units? If so Air Flow makes two different kits for Dometic. How do you tell which dometic AC do I have! They make one kit to fit a dometic Penguin 2 or Atwood, and another kit for a dometic brisk air 2 or Evo or blizzard. I have AC in front bedroom and Rear garage area, both have dump vents.
Do you have a video explaining the setup across your unit when using the RV Airflow? I have a sheet that came with my grand design that talks about opening/closing the dumps when in operation. Is it different setup when you have 3 AC’s vs 2 it mostly refers to. GrDes 375RES.
Here's our video/blog: changinglanesrv.com/rv-airflow/
When you use RVAirflow, the dumps are eliminated in favor of better performance via the ducts... See the video for more details.
I didn't even know there was a middle piece in the AC duct area. After watching this video I opened up both of mine and sure enough that center divider had fallen over in each one. I put them back in place and now I have about a 50 percent improvement in airflow through my air ducts! Now I can close the dump vents for a cooler RV and it's quieter! I am definitely getting the RV airflow system and see how much more it will improve!
Installed it before it got hot here in NE Ohio. Last year our Coleman A/C used to have to run almost continuously on high fan mode when the temps were in the 90's. And, we'd have to run the bedroom A/C to knock the temp down before bed. Now with this installed our A/C runs for a few minutes at a time, at low setting, on even the hottest days. And, we haven't had to run the bedroom A/C at all! Also, it now blows so hard-even on low setting-that it blows the dogs hair around while she's laying on the floor! Awsome product!
am i able to get a thing of foam and cut it to make my own custom one?
In which video did you install the little rubber door stops into the vents - can’t seem to find it after watching a few of your videos? Also, did they provide any noticeable difference?
Going back to testing airflow before and after installing the RV Airflow system. what setting on your Anemometer did you use? CFM,CMS or CMM?
1 Thing I did to my standard AC system not having these Air flow devices was put foil tape over the slider vent on the inside of the cover to keep it from vibrating open and rattling while the units are running. Nothing worse than a rattle while you are trying to watch TV, since those slide vents are now obsolete with the Air flow system it wouldn't hurt block them off, this will prevent accidental opening and recirculation of air back into your unit. My OCD for rattles and noises is always in full effect while driving a vehicle or in an RV, I will not rest until I find the rattle or squeak and have it fixed.
Our ac are Demedic not Colman. Will they work with demedic?
Yes.. they have units for Dometic also.
@@ChangingLanes Thank you
Maybe adding a question you've already answered, but did you guys measure the actual temperature of the air coming out of your supply vents? You can pick up an infra-red thermometer like what they're using to check your forehead on Covid screening to measure it. One good way to measure the efficiency is to check the temperature of the air going into the unit, and the air going to the living space (supply air) , then measure the difference. You probably want to see between 14 and 22 degrees on A/C. The closer to 22 (or above) you are, the more efficiently the unit is working overall.
I haven't measured the temps, just the air speed from the vents. It went from 8-9 mph to 18-20mph and now my wife complains that "It's Too Cold". This product saved me from adding a second AC unit to my trailer. Best Mod I have ever made to my 4 year old Starcraft!
to tighten down the 4 lag bolts the manufacture (Coleman) has gauge strips in the foam rubber seals for proper tightening. With this over prices piece of foam you can not use Coleman's method of proper AC lag bolt installation. Using 40 inch pounds with a 1 inch thick foam rubber seal I don't think so!
Before I removed the 4 lag bolts I measured their lengths, as well as marking them with white paint. You are correct in stating that the foam insert blocks the view of the gauge strips, but only two of them. When reinstalling the lag bolts I did use a torque screw driver and set it at 40 pounds. It was soon obvious to me that 40 inch pounds was way too much: my foam gasket looked very compressed and the bolts that I could see were no where close to the measurements I made before removal. I loosened all 4 and re-tightened, watching the two gauge strips that I could see, and the marks on the bolts that I made before removal and the torque came out to be right at 20 inch pounds. The foam gasket looks like it did before I removed the bolts, and a check with a water hose confirmed there was no leakage. I plan on rechecking the bolts at least once a year.
I installed an RV Airflow, in March 2021. "WOW", what a difference. Had to turn the A/C vents in a little different direction. Wife was complaining of the air blowing directly on her was "TOO COLD". Also noticed a difference in, when we had to run the A/C. Due to the moisture on the windows, when just running the furnace only (high humidity). The humidity level decreased substantially , and the windows cleared up. THANK YOU R/V AIRFLOW for this product.
👍🏼 😀 Glad you like them!
@@ChangingLanes
Vacation starts this Saturday, Sequoyah state park, outside Tulsa okla. You need to check that place. It's our 2nd time there.
What type and brand of filters do y'all use for your AC units?
Thanks for reaching out. You can find info on the filters in the attached vlog article: changinglanesrv.com/spare-parts-full-time-rv-life/
So how did you keep that divider from falling again after you "just pushed it back up"?
The divider is removed completely with the RV Airflow. it's not needed.
I have a 2021 Forest River Cardinal Luxury that has Dometic air system. It has only small round vents in the ceiling , 6 in main living area 4 in bedroom & 1in bathroom. There are 10 return vents. I am in Abilene been over 100 for days Run air at 78 to 80, run both air conditioners about 6-7 hours a day . What is the difference?
Did you measure Db's by chance... did it make your air unit quieter?
Just ordered two for our Arctic Wolf 321BH. We have the Coleman Mach3 A/C units. Thanks for the coupon code, saved me $34!
👍
I have a Arctic Wolf 321BH with one AC. It will not keep cool even on an 80 degree day. Have not checked the divider problems, but still think I need more help. Did this do the job? Can you cool your unit with just the main AC and the AirFlow?
@@gabegundersen9681 I haven't tried with just one. I've always been on 50amp. But we just went to Disney and it was 98 degrees in the rig when we got there. It was down to 70 degrees in about 45 minutes. These things rock.
@@RonnieRukus Thank you!!! Will be ordering ASAP.
hi
Talking on the opportunity for leaks on around 4:55 mark......we have same Coleman AC and where that upper white plastic and lower white plastic meet isn't 100% perfect. Our bedroom AC has a whistle if you don't slightly open a dump vent. Press up the center of the bottom white cover a little (dumps closed) and whistle goes away. I think there's a deformity of the plastic a bit where the 2 meet and form that channel. Been meaning to devise a seal with thin closed cell foam tape.
Hey were you in Phoenix Arizona??? I was driving by and saw a three axle RV and noticed it had cameras and I think it was you guys! When I saw the cameras I figured it's gotta be a TH-camr. Thanks for all you do guys appreciate you!
Love the idea, but spending 170 bucks on 75 cents worth of foam is out of control.
I put it in my view and it didn’t make it Quieter are used a noise meter and then go down any decibels at all
Its primary function is airflow, not noise reduction. We've heard these do well for noise and work with the airflow.
wackoproducts.com/
Now because I basically just unattached the AC Unit do I need to reseal it on the roof?
Can't believe I'm just seeing this! I've seen about a dozen of the blue foam board DIY's. Who'd have thunk--airflow should be aerodynamic. Love your channel!
great video thanks just ordered the airflow. werner the v twin biker from vermont. you two are one of the best .
I modified my plenum to achieve the same result using foam board. It's not as nice looking, but since the part wouldn't fit my A/C I had no choice. Besides the cost is high for a piece of foam. No one talks about the duct work itself. The 4" vents used don't let out that much air & are noisy. What I did at the end of the run (last vent at the front & back) I removed the vent, cut a hole big enough to put a regular house vent in. The ducts are about 3" x 8" so the size fits. This reduces the pressure in the ducts allowing increased airflow.
Does this upgrade work well with units that have a heat strip?
Where do I find the discount code?
Things like that are always in the description below the video... Our code is CHANGINGLANES. 👍🏼
Great video/info! My ac struggles on hot/humid mid-Atlantic days. Hoping this (and proper ac maintenance) are the answer.
While my 5th wheel has ducted ac, only the front bedroom ac has a plenum accessible from the inside. The rear ac vents etc. for maintenance are only accessible from the inside of the ac unit (removal required). It’s a poor design for sure and I’m assuming I would only be able to use this on the front ac? Or is that a question best left to the manufacturer?
How do I get the discount code? I have three air conditioners in my Grand Design 350M and after watching this video, I want to put this in all three units! Also, have y’all ever swapped the garage 13.5k BTU unit with the bedroom 15k BTU unit? The bedroom is a much smaller area and the 13.5k BTU unit is much quieter. Seems the swap while installing the RV Airflow unit would make good sense. Thanks!
Looks like an easy item to 3d print
Is this something you still use? Would recommend ?
Yes and yes. 👍🏼
With adding the new airflow system does that quiet down your AC inside your RV?
I’m about to install one and I wanted to know if you felt that there was any reduction in the noise? I’ve seen some people talk that it has reduced the decibel level a little bit. I just didn’t know if that was your experience
Walking back to our rig today we spotted a Momentum with the RV Airflow logo. Turns out it was Richard and his wife. Great people, and of course we walked away with two units for our Grand Design 310 GK. Thanks for letting us know about this product.
Awesome! I hope they gave you our 10% off.. 😊
@@ChangingLanes Gave us the show deal. $40 off and no shipping! Going to install them Sunday when we get the “Sea Shed” back to Galveston. Give them the Texas test. Safe Travels. Love your channel. 😊
Even better!!! 👍🏼
is this only effective for larger rv s with a ducting system?
Got one....installed it.....very impressed!!! Kids bunkroom went from hottest area to one of the coolest areas!! I would HIGHLY HIGHLY recommend!
Glad you had a great experience! 👍🏼
@@ChangingLanes only downside is vent closest to unit has "blow by"...air is flowing so Fast it goes past the vent. All other vents have massive airflow Increase
Try putting these just inside the vent (adhered to the top of the duct). amzn.to/3oEdamW We did this when we did our AC maintenance a year ago and it seems to help disrupt the flow and get it out the vent. 👍🏼 It's in this video: th-cam.com/video/Gbm8hOyZlrU/w-d-xo.html
Is this recommended for a single ac unit camper ?
Only if it's ducted.
There is an article in our blog post here:changinglanesrv.com/rv-airflow/
I am in a 20011 cedar creek 36re and I work and live in Texas and could use 40 percent increase. I am going to measure this evening. On my Dometic AC on my central unit. My bedroom has a different set up but will follow up on that after I tackle the main unit. Thanks I will be sharing this info with coworkers that live in RVs.
Don't forget the vent nubbie seen in this vlog changinglanesrv.com/rv-mods-and-organization-for-rv-living-1/
This is going to be a lifesaver for those with only one A/C unit on their 5th wheel this summer. No more sleeping hot.
👍
Although this won't fit my ac unit, your video did solve my cooling issue: I removed the air intake to measure the plenum and noticed that a piece of blocking insulation was tilted over, EXACTLY like yours was, causing much of my cool air to be recycled. I put it back correctly and it is cooling MUCH better now! Thank you, as I was getting ready to drop a grand on a new a/c unit. Cheers !
Awesome! Also check out: th-cam.com/video/Gbm8hOyZlrU/w-d-xo.html
Ordered!!
Great job!
Did you notice that if you only have one of the multiple units running that the air comes out of the return side?
It shouldn't, unless it's pushing past the evap coils on the units that are off....
@@ChangingLanes exactly what it does.
Maybe try removing some vent covers to reduce resistance on that end?
So your video was one that helped me decide to add 3 of these to our 351M. Well...We just spent a week at Lake Havasu in 114 temps and the trailer maintained 74 the whole time! Great product!
AWESOME!!! 😀
The price of this is $380. You can go to Home Depot and get the same thing for $30
That's bogus...where did you get the $380 number?? Good luck with your $30.00 dollar HD cheap fix. RV Airflow is well designed, works better than advertised, and saved me from buying a second AC for my trailer. Post some photos of your project....
Just got finished installing in my 2019 Thor Challenge(r) 37TB. With some minor adjustments, there was no fuss no muss getting this done. I was prompted to call the manufacturer with a question and received a return call within minutes. The gentleman walked me through some suggestions that worked.
👍
The foam arrived. I installed on living room A/C. The plastic pieces you installed into the supply side ducting were already installed in mine. I had to install tape around the foam on the return side to seal it off from the supply side. I have a 2021 momentum 376THS. Will try to install the other 2 tomorrow.
How did the system improve overall?
@@flawlessvic Western Washington cooled way down. Haven't had to use the A/C since. We are supposed to get into upper 80's this weekend. I will test them then.
Can you post a link to the round inserts you have inserted into your ceiling vents to create a disturbance to the air will be forced down?
You can find those here in the Products section under Vent Nubbie changinglanesrv.com/rv-mods-and-organization-for-rv-living-1/
@@ChangingLanes thanks! Ordered.
It does eliminate any cooling air directly coming out of the AC unit as all air is then directed to the roof vents. That may raise sensible temp at the living area under the unit.
perhaps.. but opening those dumps lowers the temp everywhere but directly under the AC... plus much of that energy is lost, being pulled right back into the AC... The feedback we've received and also what we've experienced is the heating and cooling with this kit is very much improved overall.
My God,...it took you for ever to say and show all of us,....what could have been easily under five minutes!
Calm your udders, Karen. That what the fast forward ability is for. There’s plenty of people that appreciate the explanation of how/why. Especially when it comes to spending hard earned money.
