I'm continuously amused by the severe lack of engineering / design of these RV manufacturers and their vendors. They build cheap crap knowing fully that its garbage and then 3rd party companies (like the inventor of this product) actually design something that WORKS and we have to then spend more $$$$. It's absolutely amazing. I guess that's what makes the economy continue to work. Either way, you always have the BEST reviews and install vids AND the best bloopers! Appreciate you both.
The RV industry is a joke. There are no standards and they have a bunch of minimum wage guys throwing these things together as fast as possible to make their quotas to make their bonuses. Most QC is poor as well. I know 2 people that worked for Monaco coach here in Oregon and they both said nobody really cared about quality. It was just getting them out ASAP.
@@uowebfoot you're not kidding...it really is about how quick they roll them off the production lines. But, it's not just RV's, it's new homes too. We just bought a new home (almost done being built) and these builders don't give two shits about quality. There's no pride in workmanship anymore in this country on anything...very sad.
If they built to higher standards the average buyer would not pay the significantly higher cost, since the average RV buyer only looks at only the floor plans, colors etc. Often what makes a better or higher quality unit is not readily seen or touched. The RV market is highly competitive. Further they know that for those RVers who appreciate quality will make improvements through the after market.
@@hermes6587 Your point is somewhat valid. However, my father has owned several RV Bus Motorhomes well over 100K in price and they fall apart just as bad. So high price does not mean better quality.
@@wannabefulltimers My wife and I looked at a home built in 1957 and it had everything top of the line from that era. Everything was like brand new and bullet proof.
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!
You guys have really done a great job with explaining the important elements and paying attention to measurable details. I was tweaking my ac due to the obvious design flaws. This is the best option. My dad was a mechanical engineer and he always said you can't beat an engineer with a pair of pliers. Time and money saved here for sure. Thanks!
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
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.
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!
We just bought a Grand Design 2670MK and I was thinking about installing this as an early upgrade. When I opened up the cover to look at my AC box, I noticed that it was already installed. Looking at the website in the link, Grand Design started installing these at the factory in June and I can attest that this is true. Happy surprise!
Watched another guy too, where he cut out all the vent slats in the ac cover on the roof and replaced them with wire mesh. That alone made a huge difference in his cooling ability. Combined, this would be amazing!
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
Just installed the RV Airflow System. Straight forward installation and the airflow increase is as advertised! Thanks for the discount, it's worth every penny.
I built my own with some old styrofoam and duct tape, the results were amazing and it only cost me five bucks and 90 minutes of my time!!! Everybody should do this upgrade to there AC units!!!!
Same here. Went with reflective Styrofoam from Lowes (1/4"). Built a t-pee shaped "duct guide". With reflective duct tape, total project cost: $8 for two units. Now my ACs are BLASTING out the cold air and easily keeping up with Florida temps and I saved $232
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!
Installed mine last weekend at the Texas Un-Rally. Richard and Joanne are wonderful people and very helpful. True RVers not just there to sale participated in all of the events.
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.
Installed this upgrade a couple of weeks ago and we just had temps high enough for a day or two to try it out. The increased air movement is wow!! Makes the window shades move a little. Started with an 84 degree inside temp and after about 45 minutes it was down to 77 and cycling properly. It will be well worth the cost. We have a 2nd unit in the bedroom that we run during the day on Hot days with a small fan on the dresser moving air into the living area which helps. The big change will be at night when we only run the main unit. Now the bedroom will be easier to cool with the increased air movement. The one thing I found during installation was after centering the a/c unit I still had a small space between the sides and the duct opening. I added a thin foam strip around the opening on the insert and it fit nice and snug. If you have a ducted unit that this upgrade applies to by all means get it.
We just spent the weekend in Quartzsite, Arizona, where the temperature was 85 degrees on Friday and Saturday. This was our first trip where we could do a real world test with the RV Airflow installed in our Coleman Mach 15k AC. Prior to the install it took quite awhile to reach the set temp on the thermostat once we plugged into shore power. It was 85 outside and 81 inside when I first powered up the trailer. I set the thermostat to 76 degrees and within 30 minutes the AC shut down and the inside was a cool 76 degrees. That's never happened that quick before. During the day when the AC restarted it only ran a few minutes before it reached the set temp and shut down. It has never done that before either. It used to run quite awhile before reaching the set temp. It also seemed to run a lot quieter because when it ran we didn't have to turn up the volume on the TV like we did before. Needless to say we are both impressed with the great improvement. It works better than we expected and so glad we found this video! Best mod I have made to my trailer since new!
I just wanted to write my first comment to you both and thank you from the bottom of my heart for your all your videos. I am receiving my AirFlow units in a few days and can’t wait to get them installed. I am just a single guy, full time in my 351M and winter in Arizona and summer in Wisconsin. I have followed your advice and recommendations for more things then I can count, including removing my rear benches and making that a wrap around desk since I work from home as well (Network Administrator). You both are amazing at your thoroughness and detailed descriptions that take pretty much any questions out of not only how to do it, but if it’s worth investing in it. And you always make it fun to watch as well. Thank you again so very much, and I hope one day our paths will cross!
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!
Installed this product last week and EXCELLENT improved airflow. I did have spacing problems with the vertical divider so I totally eliminated this on my Dometic unit. So I just have the bracket with the long lag bolts. Thank you for the video. It gave me the know how and confidence to do it myself.
Here's a way to take some of the frustration out of getting the lag bolts lined up. Buy yourself threaded rod and cut it into two pieces. Install the rods in opposing corners put the box up with two of the lag bolts in the other holes. Then replace the rods with the other two lag bolts.
Just installed this modification this morning after suffering through 100(+) heat this summer. After watching your video and a few others the installation was a snap. Without measurements I believe the air flow has increased at least 50% and the RV is much, much cooler. A must for RV owners. Thanks for your channel and great instruction!
Hi guys. Small correction. You're confusing "high side" and "low side" with the correct terms, "supply" and "return". The high and low sides refer to the refrigeration circuit high pressure side and low pressure sides.
Thanks for that. I was confused too. Seems rather expensive for that bit of foam and plastic. But the video sure helps and tells me I need to look up there in my new RV to make sure all is the best it can be until I figure out a home made solution to making it more efficient.
Just now saw this. You're right. It's "conditioned air" after all, and it's got to be "conditioned" before it's "supplied" to your living space, and then "returned" to be conditioned again. 'Low' and 'high' pressure just muddies the water.
Awesome!! Any improvement in AC is worth the cost and I've said it before - and like I've said before, every time I watch one of your videos Chad it costs me a couple of Benjamins - but totally worth it EVERY time!!!! Thanks for letting us all know about this, I'm ordering as soon as I finish typing. Safe travels!
@@jeffward7502 i don’t know, sorry. I suggest you Contact them. The question is If the plenums are identical for the 29-5 (mine) and your 32-5. They will know if anyone else has installed it on the 32-5. If not it is real easy to take a few measurements and find out. They can help you with this. Let me know if you additional assistance. Good luck. Love the 32-5. That is the model I wanted to get. But I’m happy with mine.
Wow this is awesome! We have been making our own version of this for years and it is nice to see a company that address the need for this. Thank you for showing the testing numbers and results because that mean a lot to us! You guys are awesome. Thank you.
OMG! You were cutting with blade towards your hand! I have had to take too many people to ER when knife slipped in that situation! They didn't think it would happen to them either. So yes, I raised and Eagle scout, but that was scary to me! Yes Daisy time is also important! You know she is really the star of the show! LMBO!
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.
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.
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.
@@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. 😊
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 🙏🏼❤️🤙🏼
I know this is an old video but it is by far the best one. I just installed mine and your video had EVERY question I had, answered. Thanks for the discount also. Hope to see you guys out there
Wow!!! When someone comes up with a idea/product such as this, the RV industry should embrace it and ensure ALL rigs have this. I know u guys said that GD has implemented this into the center AC, but unsure on what units. Come in RV industry, lets get into the 21st century!!! Love you guys content in tutorials and adventures!!!!
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.
Been watching you kids for a few years now and just wanted to tell you we just bought a new Grand Design Reflection 5th wheel and they are NOW installing the RV Airflow in the AC units. I took mine apart to check before I ordered one, and WOW it is already installed. Makes a HUGE difference in the cooling and air flow.
Finished installing this in my 2013 Montana Mountaineer 5th wheel. Mine is a Dometic Brisk Air II 15K unit. Did have to do a duct mod since the factory installed one side to far forward and the unit was a little forward and not square. Didn't take any readings before (wish I had) but did after. According to what I could find, this unit is rated at 350 CFM. I have a total of 5 outlets and had to check my results twice to make sure it was correct. Assuming that my wind speed indicator is reasonably accurate, converting MPH to CFM I get a total of 570.55 CFM from the sum of all five outlets. The air flow is greatly increased, by feel, from what it was before. More supply air creates more return air = cooler RV. Will have to wait till we're out camping in hot weather before I can say this will keep our rig cool. Have high hope.
As an aviator in the army and Air Force, we always kept our torque wrenches with pressure on the springs by keeping them at 10% of the rating. Foot, inch or ounce. Leaving the spring at zero allows it over time to expand and or contract and lose accuracy or go below and cause errors.
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 are the best. Love your outtakes. My camper is currently 81^F and its only gotten up to 89^F outside. I was going to purchase some foam board today and fabricated something similar but it looks like I need to spend the money to capitalize on this engineers great product.
One installation tip: When inserting the unit and it seems to get stuck, remove it and use a solution of dishwashing liquid and water to coat the foam and the outside edge of the duct covers, the re-insert. Makes it a lot easier.
I watched your video and I thought what a great idea. So I had to go out and look at my AC on my 2018 Coachman Freedom Express. The Furrion AC is already built this way with separate chambers. But it gave me an excuse to wash my filters.
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 !
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.
I have a new 5rh wheel and I just installed one thanks to your video. My wife and I are going camping for the first time this weekend (in our new one). We haven't even ran the AC yet so we won't have a baseline to compare it to... We're taking your word for it. Thanks for the great 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.
Excellent video. We have a new 2022 Reflection 28BH manufactured in August 2021. Grand Design did a fairly good job with the AC install. I first thought that our single 15,000 BTU Coleman AC unit had the original design, but it actually does have the new plenum box. However, it was poorly installed. There were a few vents that had very little airflow, I could hear turbulence in the system, and the system didn't cool as well as expected. When I took things apart I found that the duct openings didn't fully align with the openings in the Styrofoam box, and the rubber gaskets were all pushed out of place so the seals were less than perfect. There were also several large gaps in the raceway duct openings. I metal taped the gaps in the duct work, fixed the rubber gaskets, and carefully aligned all the openings during re-installation. There was a significant airflow improvement and less noise from air turbulence. Chad, you did a wonderful job explaining and measuring the system and flow improvements. Thanks!
Excellent explanation of the product. I had one installed last year at the Grand Design rally in Quartsite and have been very happy we did. Great people that own the company. Fives stars on the product.
We have a 37' Keystone travel trailer with a 15,000 coleman ducted main A/C, and a suplimental 13,000 in the bedroom. During the hottest times, the main unit held it's own, but had to work kinda hard sometimes to maintain temps. We would only use the bedroom A/C to knock the temp down as it got close to bed time, then turned it off because it sounds like a 747 coming in for a landing, lol. This product should help the main A/C do the job on it's own without having to work too hard, so, I ordered it before your vid was even finished playing! Thanks guys!
That is really cool. 😎 I wish we knew about that for our other TT. We now have a Ceader Creek 5th Wheel - 388RK. Our AC does not have that kind of intake. This makes it so much more efficient and no noise. Our last TT AC was like the one you're showing. It was so loud we could hardly hear each other talk.
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!
@Changing Lanes: Just wanted to say "Thank you!" for doing this video. I have a 2020 Grand Design Reflection 150 5th wheel (about 32ft long or so) and am a full-timer in an RV park in Florida...so even though my unit is brand new with a 15K Mach 10 in the main area and a 13.5K Mach 10 in the bedroom, they still struggled to keep it cool this summer without me having to run them all the time and typically lowering the thermostats to 48-50 degrees just to get the room temps below 74 for a comfortable amount of time. Anyways...after your video I went on the RV Airflow site and ordered 2 units. Thank you for the 10% discount code also! :) Ordered them on the 27th, and they arrived yesterday afternoon. Thanks also to your video for recommending the Wheeler torque wrench to get the torque correct on the 4 big bolts. I also ordered that on the 27th and it showed up 2 days later, so I was ready to get to it yesterday as soon as the Airflows arrived. I did the living room 15K system in about and hour and 20 minutes w/ minimal issues like getting the 2 big bolts to line up again once the Airflow was inserted...no big deal though, and I feel real good knowing those bolts are torqued properly again to 50 pounds. I then did the bedroom unit in about the same amount of time, basically due to one of the bolts fighting me to line up and thread properly, but again, no biggee and the job was complete. I had no way to test airflow before and after other than just by "feel" with my hands at the vents, etc. But I am writing to let everyone know that these things work big time! My rig was about 75 degrees after finishing installation and then I cranked up both units. The airflow out of the vents was like a tornado compared to before, so right away I knew these things increased airflow as advertised. My single ceiling vent in the bathroom was closed and the airflow was so strong the air was making a screaming sound from the air being pushed through the closed vent so powerfully. That never happened before. I could also tell immediately that the air coming out was much colder than before. So I turned off the bedroom unit and just tested with the living room. Normally, with only using my living room unit when the rig was at 74 or 75 degrees and putting the unit on High setting down to 48 degrees or so, it would still not be able to cool the room down more than just a degree or 2 on its own. So I always had to use both systems at the same time to get the living room to drop down to 68 to 70 degrees with both units on High cranked way down. That would usually take 15mins or so. Well that's all changed now. I cranked the 15K down to just 55 on High and it dropped the living room temp down to 66 degrees in about 12 mins all on its own without using the bedroom unit!!!! That proves it right there. When I ran both units on High they turned this place into an icebox in no time at all. I got it down to 63 degrees and was freezing my tail off, but that proved how much more strong and efficient the units are now with the Airflows installed. People may think these are a little expensive...but the 10% discount certainly helped out. And also, I would estimate they will easily pay for themselves over time because I can already tell I won't be running my units as long anymore which will definitely decrease the monthly electricity bill. Anyways...that was a quick, easy, painless modification that works amazingly well. This is how A/C units should now come from the factory. Slam dunk upgrade!!! Just wanted to let everyone know how well these work. You do a terrific channel and I watch all time since finding it several months ago. Thanks again for this and all your other videos!
@@ChangingLanes yeah, since I'm in Tampa and have had to work from my RV full-time since the you know what happened, I've had to run the A/C's all day all summer long. Luckily, my RV park is full of nice big oak trees, so I'm totally shaded, but it's the humidity that gets ya down here ;-) Wish I had found out about these things about 6 months ago, because I'm sure my monthly electric bill would have been greatly reduced. I think I'm averaging about 100 bucks a month or so, give or take maybe 10 to 12 bucks I guess. But I'm anticipating that to drop at least 10 to 15 per month thanks to this upgrade. One other recent thing to note for anyone reading this. After the installation the other day, my living room unit started making a rattling vibration like a fast "ticking" sound when it would turn on. I put up with it for a couple days, and when I would push my hand up on the shroud or ceiling plate it still wouldn't stop ticking. So yesterday I took out the filter cover and filter on the side the ticking sound was coming from, and that exposed the big through-bolt on that corner of the unit. When I pushed up on the metal frame where that bolt was the ticking vibration would stop. I only cranked those through-bolts to about 47 or 48 pounds with that Wheeler torque driver just to leave a little room for error. So I grabbed the driver and adjusted it to 50 pounds and gave that bolt a few cranks to 50 pounds and bingo...no more annoying ticking sound!!! Luckily that particular bolt was the cause/cure of the vibration and I didn't have to remove the shroud to get at a bolt on the covered up side (towards the rear of the RV side). So anyways...if anyone installs these and uses the torque driver for the big bolts (which I also highly recommend), and if you leave a little room for error under the 50 pound setting and then hear a bit of a vibration, try to isolate which bolt(s) that might need a pound or two more tightening and hopefully it will take care of the vibration. The bedroom unit was also torqued to like 47/48 pounds but it has no vibration and even sounds a bit quieter than before this upgrade. I also still can't get over the amount of force both units have now. It's like a TORNADO in here now when they're both running, and they cool this thing down twice as fast as before. Like I said before...they may seem kind of expensive...but for full-timers who want to reduce your electric bill and make these systems run more efficiently and COLDER, they will be worth the cost, because you will definitely reduce your electric bill each month and they will pay for themselves over time for sure.
THX for the PSA on torque wrenches. I calibrate them and a personal pet peeve is clicker torque wrenches not set to minimum. The internal spring develops a memory when kept compressed for long periods of time.
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.
@@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
The outtakes show just how much work and prep goes into one of these reviews. Thank you both for all your hard work that probably at times seems like play. Safe travels and God Bless...
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.. !
Just learned about these. Thx for the vid and sharing the numbers. Did you notice any decrease in the sound levels from the ac running after installing the kit?
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.
It's a good concept and glad you put it out there. The problem with so many TH-cam videos is that they aren't planned well nor rehearsed enough. This could have been much more precise and less boring if you would have done in two third the time.
Installed yesterday and let me tell you! WOW!! Turned on the ac after install and it blew out so much construction debris from all the vents. 100% worth it. For reference I have two Coleman Mach 15 Air-conditioners on a Arctic Wolf 3770 Suite 43 foot. Thanks for the 15% off too !!
Recently installed in our GD Solitude 390RK and had a few 90+ days to check it out. I felt cool air flow in areas I hadn't felt before. Totally awesome they work great !
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.
I am a air-conditioning contractor and I think that’s an awesome set up but the price is a little bit steep usually if you wait a while it might come down hopefully specially maybe towards the summer
Hey guys, thank you for the RV Airflow video. I just received mine today and worked for hours installing it. Where the Manufacture framed in the opening in the roof it was LESS than perfect! Not square, Unit not set on roof square, duct with large gaps, opening too small for main piece...etc. After watching your video, It prepared me for some of these obstacles. My rig is a 2018 Avenger by Forest River. To give you an idea how poorly it was installed my average increase is 61%...a noticeable difference. Thank you again for the excellent videos and information!
Thank you guys, used the promo code and it worked great. Cannot wait to install it. Your video sold me on this product as I knew the way these were set up made them inefficient and killed airflow out of the vents. Thanks again!
Great video! I put them in our 2021 Momentum 397TH and love the difference. Confession, I put them in the bedroom and main A/C back in August. I finally got around to doing the garage last Saturday.
What about installing a Mini-Split unit ? I know their will be a lot of things to figure out. You could install the outside unit on the RV rear bumper. Since its DC it could run right off your batteries. After starting up the unit should pull around 600 watts. These Mini-Split have a rather great efficient rating. Also they are much quitter than the factory installed units. They could be installed directly into the RV. No more possible leak from being on top. Just a few things that I was kicking around. I know it would be a lot of work first installation but wow.
NOTE! Our AC is an AirXcel / Coleman and that's what's currently available for RVAirFlow. However, they are working on models for other units also, so keep an eye on their website! 👍🏼 Also... This is only for RVs with ducted systems.
@@CartersTrail In the video they installed one in the bedroom and when talking about the numbers they go over the improvement of all 3... did you watch til the end or ?
I had one installed this weekend in our Imagine at the Grand Design Texas un-Rally and it improved our airflow by 30-48% across the 6 vents. We already had the Wacko RV AC Silencer and it is compatible with that product and decreased the decibel level a little bit as well. Thanks to Richard Stark and the RV Airflow team for this product. It will help during the hot Summer days in South Texas.
We put these in our Solitude 310GK, and supplemented it with the "RV AC Silencer" from "WackO Products". This definitely improved air flow, but also brought the fan noise down to where we don't have to adjust volumes on the TV. While you can still hear it, it really doesn't interrupt the "vibe" of the camper anymore. I'd love to see you guys put these silencers in and measure any decrease/increase in air flow and nose levels! On top of this, it does completely eliminate the air dumps.
Awesome job, very straight forward video on the installation. I am a HVAC guy and am totally impressed. We also have a Momentum with 3 units, living mostly in Texas and that will really help.
I have found that after the unit sits for a day you should retightened all bolts as the foam gasket compresses. Don’t want leaks. Thanks for the information
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!
Thank you! I watched your installation video and had my AC ready to go when the package arrived. I had it installed in about 40 minutes. The only problem I had was sliding the foam into place because it was very tight around the plastic duct inserts. Mixed up some dish washing liquid, put a light coating on both the foam and the inserts and it just slid right in. Perfect! Buttoned it up and ready for the big test. I have a wind meter and before the install I measured between 7 -9 mph at both ends of my trailer from the ceiling vents. After the install I measured between 18 and 21mph! So breezy it blew the install sheet right off the table! Now my wife is worried it will be getting too cold in the trailer with the AC on. My RV is a 30 foot Starcraft Autumn Ridge 266RKS travel trailer with a 15k Coleman Air Conditioner. Can’t wait for the summer heat to really try it out. Used your discount code and saved a few bucks. Love watching all of your videos! Lee A. Kingman, AZ
I'm continuously amused by the severe lack of engineering / design of these RV manufacturers and their vendors. They build cheap crap knowing fully that its garbage and then 3rd party companies (like the inventor of this product) actually design something that WORKS and we have to then spend more $$$$. It's absolutely amazing. I guess that's what makes the economy continue to work. Either way, you always have the BEST reviews and install vids AND the best bloopers! Appreciate you both.
The RV industry is a joke. There are no standards and they have a bunch of minimum wage guys throwing these things together as fast as possible to make their quotas to make their bonuses. Most QC is poor as well. I know 2 people that worked for Monaco coach here in Oregon and they both said nobody really cared about quality. It was just getting them out ASAP.
@@uowebfoot you're not kidding...it really is about how quick they roll them off the production lines. But, it's not just RV's, it's new homes too. We just bought a new home (almost done being built) and these builders don't give two shits about quality. There's no pride in workmanship anymore in this country on anything...very sad.
If they built to higher standards the average buyer would not pay the significantly higher cost, since the average RV buyer only looks at only the floor plans, colors etc. Often what makes a better or higher quality unit is not readily seen or touched. The RV market is highly competitive. Further they know that for those RVers who appreciate quality will make improvements through the after market.
@@hermes6587 Your point is somewhat valid. However, my father has owned several RV Bus Motorhomes well over 100K in price and they fall apart just as bad. So high price does not mean better quality.
@@wannabefulltimers
My wife and I looked at a home built in 1957 and it had everything top of the line from that era. Everything was like brand new and bullet proof.
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!
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
Been binging you guys backwards cuz I started watching ya late n am loving going back. I’m addicted now. ❤️❤️
You guys have really done a great job with explaining the important elements and paying attention to measurable details. I was tweaking my ac due to the obvious design flaws. This is the best option. My dad was a mechanical engineer and he always said you can't beat an engineer with a pair of pliers. Time and money saved here for sure. Thanks!
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
Being an HVAC tech I installed sheet metal scoops. doubled my air flow
Can you send me pics please?
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.
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!
We just bought a Grand Design 2670MK and I was thinking about installing this as an early upgrade. When I opened up the cover to look at my AC box, I noticed that it was already installed. Looking at the website in the link, Grand Design started installing these at the factory in June and I can attest that this is true. Happy surprise!
Watched another guy too, where he cut out all the vent slats in the ac cover on the roof and replaced them with wire mesh. That alone made a huge difference in his cooling ability. Combined, this would be amazing!
Just installed and literally blown away. Well worth the price and install was a piece of cake. 1000% recommend.
Thanks Chad.
I just ordered mine.
I told them I heard about their product on your channel and I got 15% off!
Thanks guys!
Great video/info! My ac struggles on hot/humid mid-Atlantic days. Hoping this (and proper ac maintenance) are the answer.
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
Just installed the RV Airflow System. Straight forward installation and the airflow increase is as advertised! Thanks for the discount, it's worth every penny.
I built my own with some old styrofoam and duct tape, the results were amazing and it only cost me five bucks and 90 minutes of my time!!! Everybody should do this upgrade to there AC units!!!!
And saved yourself $170!
Same here. Went with reflective Styrofoam from Lowes (1/4"). Built a t-pee shaped "duct guide". With reflective duct tape, total project cost: $8 for two units. Now my ACs are BLASTING out the cold air and easily keeping up with Florida temps and I saved $232
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!!! 😀
Installed mine last weekend at the Texas Un-Rally. Richard and Joanne are wonderful people and very helpful. True RVers not just there to sale participated in all of the events.
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.
👍
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.
Installed this upgrade a couple of weeks ago and we just had temps high enough for a day or two to try it out. The increased air movement is wow!! Makes the window shades move a little. Started with an 84 degree inside temp and after about 45 minutes it was down to 77 and cycling properly. It will be well worth the cost. We have a 2nd unit in the bedroom that we run during the day on Hot days with a small fan on the dresser moving air into the living area which helps. The big change will be at night when we only run the main unit. Now the bedroom will be easier to cool with the increased air movement. The one thing I found during installation was after centering the a/c unit I still had a small space between the sides and the duct opening. I added a thin foam strip around the opening on the insert and it fit nice and snug. If you have a ducted unit that this upgrade applies to by all means get it.
We just spent the weekend in Quartzsite, Arizona, where the temperature was 85 degrees on Friday and Saturday. This was our first trip where we could do a real world test with the RV Airflow installed in our Coleman Mach 15k AC. Prior to the install it took quite awhile to reach the set temp on the thermostat once we plugged into shore power. It was 85 outside and 81 inside when I first powered up the trailer. I set the thermostat to 76 degrees and within 30 minutes the AC shut down and the inside was a cool 76 degrees. That's never happened that quick before.
During the day when the AC restarted it only ran a few minutes before it reached the set temp and shut down. It has never done that before either. It used to run quite awhile before reaching the set temp. It also seemed to run a lot quieter because when it ran we didn't have to turn up the volume on the TV like we did before.
Needless to say we are both impressed with the great improvement. It works better than we expected and so glad we found this video! Best mod I have made to my trailer since new!
Just installed those in our Reflection. Holy crap what a difference. We were instantly able to feel how much more air it moves. Did not disappoint!
I just wanted to write my first comment to you both and thank you from the bottom of my heart for your all your videos. I am receiving my AirFlow units in a few days and can’t wait to get them installed. I am just a single guy, full time in my 351M and winter in Arizona and summer in Wisconsin. I have followed your advice and recommendations for more things then I can count, including removing my rear benches and making that a wrap around desk since I work from home as well (Network Administrator). You both are amazing at your thoroughness and detailed descriptions that take pretty much any questions out of not only how to do it, but if it’s worth investing in it. And you always make it fun to watch as well. Thank you again so very much, and I hope one day our paths will cross!
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!
I installed this on my last two RV's and is amazing. The difference in air flow is tremendous. Cools faster and much quieter. I would recommend.
Installed this product last week and EXCELLENT improved airflow. I did have spacing problems with the vertical divider so I totally eliminated this on my Dometic unit. So I just have the bracket with the long lag bolts. Thank you for the video. It gave me the know how and confidence to do it myself.
Here's a way to take some of the frustration out of getting the lag bolts lined up. Buy yourself threaded rod and cut it into two pieces. Install the rods in opposing corners put the box up with two of the lag bolts in the other holes. Then replace the rods with the other two lag bolts.
Good tip!
That would be a great addition to the kit.
Just installed this modification this morning after suffering through 100(+) heat this summer. After watching your video and a few others the installation was a snap. Without measurements I believe the air flow has increased at least 50% and the RV is much, much cooler. A must for RV owners. Thanks for your channel and great instruction!
Great to hear! Thanks for sharing your experience! 😊
Hi guys. Small correction.
You're confusing "high side" and "low side" with the correct terms, "supply" and "return".
The high and low sides refer to the refrigeration circuit high pressure side and low pressure sides.
They don’t like it when someone corrects them . You didn’t get a ❤️
That was a little confusing, I must say.
Thanks for that. I was confused too. Seems rather expensive for that bit of foam and plastic. But the video sure helps and tells me I need to look up there in my new RV to make sure all is the best it can be until I figure out a home made solution to making it more efficient.
@@mojotrinity4927 At least they didn't delete his comment like they did mine when I gave them a compliment but chewed out someone.
Just now saw this. You're right. It's "conditioned air" after all, and it's got to be "conditioned" before it's "supplied" to your living space, and then "returned" to be conditioned again. 'Low' and 'high' pressure just muddies the water.
Awesome!! Any improvement in AC is worth the cost and I've said it before - and like I've said before, every time I watch one of your videos Chad it costs me a couple of Benjamins - but totally worth it EVERY time!!!! Thanks for letting us all know about this, I'm ordering as soon as I finish typing. Safe travels!
I worked with the RV airflow folks back in July to create the first device for an Arctic Fox Fifth Wheel back in July. Definitely helped!
I have a 2020 arctic fox 32-5m. D0 you have to order specifically for your brand of unit?
@@jeffward7502 i don’t know, sorry. I suggest you Contact them. The question is If the plenums are identical for the 29-5 (mine) and your 32-5. They will know if anyone else has installed it on the 32-5. If not it is real easy to take a few measurements and find out. They can help you with this. Let me know if you additional assistance. Good luck. Love the 32-5. That is the model I wanted to get. But I’m happy with mine.
Wow this is awesome! We have been making our own version of this for years and it is nice to see a company that address the need for this. Thank you for showing the testing numbers and results because that mean a lot to us! You guys are awesome. Thank you.
OMG! You were cutting with blade towards your hand! I have had to take too many people to ER when knife slipped in that situation! They didn't think it would happen to them either. So yes, I raised and Eagle scout, but that was scary to me!
Yes Daisy time is also important! You know she is really the star of the show! LMBO!
I cringed watching him cut the plastic with the blade facing the wrong way, was waiting for the thumb amputation!
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.
Ordered with your discount! This was a great improvement over what we had. Anywhere in the RV, you can feel the AC blowing now. Thanks for the video!
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.
Army here also wanted to say that you are a great teacher not to many people have that!
I love the little break there where dog is positioned “to watch from your silk pillow” lol!
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!!! 👍🏼
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 🙏🏼❤️🤙🏼
I know this is an old video but it is by far the best one. I just installed mine and your video had EVERY question I had, answered. Thanks for the discount also. Hope to see you guys out there
just found this.... we are now in Houston and this is a must have, not a need. or atleast this is how Im saying it to the wife.
yall rock! thank you
Wow!!! When someone comes up with a idea/product such as this, the RV industry should embrace it and ensure ALL rigs have this. I know u guys said that GD has implemented this into the center AC, but unsure on what units. Come in RV industry, lets get into the 21st century!!! Love you guys content in tutorials and adventures!!!!
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.
Been watching you kids for a few years now and just wanted to tell you we just bought a new Grand Design Reflection 5th wheel and they are NOW installing the RV Airflow in the AC units. I took mine apart to check before I ordered one, and WOW it is already installed. Makes a HUGE difference in the cooling and air flow.
👍
Finished installing this in my 2013 Montana Mountaineer 5th wheel. Mine is a Dometic Brisk Air II 15K unit. Did have to do a duct mod since the factory installed one side to far forward and the unit was a little forward and not square. Didn't take any readings before (wish I had) but did after. According to what I could find, this unit is rated at 350 CFM. I have a total of 5 outlets and had to check my results twice to make sure it was correct. Assuming that my wind speed indicator is reasonably accurate, converting MPH to CFM I get a total of 570.55 CFM from the sum of all five outlets. The air flow is greatly increased, by feel, from what it was before. More supply air creates more return air = cooler RV. Will have to wait till we're out camping in hot weather before I can say this will keep our rig cool. Have high hope.
As an aviator in the army and Air Force, we always kept our torque wrenches with pressure on the springs by keeping them at 10% of the rating. Foot, inch or ounce. Leaving the spring at zero allows it over time to expand and or contract and lose accuracy or go below and cause errors.
I think it's different for every brand / model. Two of mine say zero and I think the big one is 30.
excellent install and demo video, I full-time in FL, and my A/C has been struggling in recent heat waves, will def get this.
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 are the best. Love your outtakes. My camper is currently 81^F and its only gotten up to 89^F outside. I was going to purchase some foam board today and fabricated something similar but it looks like I need to spend the money to capitalize on this engineers great product.
One installation tip: When inserting the unit and it seems to get stuck, remove it and use a solution of dishwashing liquid and water to coat the foam and the outside edge of the duct covers, the re-insert. Makes it a lot easier.
I watched your video and I thought what a great idea. So I had to go out and look at my AC on my 2018 Coachman Freedom Express. The Furrion AC is already built this way with separate chambers. But it gave me an excuse to wash my filters.
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
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.
I have a new 5rh wheel and I just installed one thanks to your video. My wife and I are going camping for the first time this weekend (in our new one). We haven't even ran the AC yet so we won't have a baseline to compare it to... We're taking your word for it. Thanks for the great 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.
Excellent video. We have a new 2022 Reflection 28BH manufactured in August 2021. Grand Design did a fairly good job with the AC install. I first thought that our single 15,000 BTU Coleman AC unit had the original design, but it actually does have the new plenum box. However, it was poorly installed. There were a few vents that had very little airflow, I could hear turbulence in the system, and the system didn't cool as well as expected. When I took things apart I found that the duct openings didn't fully align with the openings in the Styrofoam box, and the rubber gaskets were all pushed out of place so the seals were less than perfect. There were also several large gaps in the raceway duct openings. I metal taped the gaps in the duct work, fixed the rubber gaskets, and carefully aligned all the openings during re-installation. There was a significant airflow improvement and less noise from air turbulence. Chad, you did a wonderful job explaining and measuring the system and flow improvements. Thanks!
Excellent explanation of the product. I had one installed last year at the Grand Design rally in Quartsite and have been very happy we did. Great people that own the company. Fives stars on the product.
Bob, please contact us, either email info@rvairflowsystems.com or call (574)536-4949. Thx!
We have a 37' Keystone travel trailer with a 15,000 coleman ducted main A/C, and a suplimental 13,000 in the bedroom. During the hottest times, the main unit held it's own, but had to work kinda hard sometimes to maintain temps. We would only use the bedroom A/C to knock the temp down as it got close to bed time, then turned it off because it sounds like a 747 coming in for a landing, lol. This product should help the main A/C do the job on it's own without having to work too hard, so, I ordered it before your vid was even finished playing! Thanks guys!
You should also look at the RV Air Silencer. It made a tremendous difference in noise level on our Dometic 15k unit.
That is really cool. 😎 I wish we knew about that for our other TT.
We now have a Ceader Creek 5th Wheel - 388RK. Our AC does not have that kind of intake. This makes it so much more efficient and no noise. Our last TT AC was like the one you're showing. It was so loud we could hardly hear each other talk.
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!
@Changing Lanes: Just wanted to say "Thank you!" for doing this video. I have a 2020 Grand Design Reflection 150 5th wheel (about 32ft long or so) and am a full-timer in an RV park in Florida...so even though my unit is brand new with a 15K Mach 10 in the main area and a 13.5K Mach 10 in the bedroom, they still struggled to keep it cool this summer without me having to run them all the time and typically lowering the thermostats to 48-50 degrees just to get the room temps below 74 for a comfortable amount of time. Anyways...after your video I went on the RV Airflow site and ordered 2 units. Thank you for the 10% discount code also! :)
Ordered them on the 27th, and they arrived yesterday afternoon. Thanks also to your video for recommending the Wheeler torque wrench to get the torque correct on the 4 big bolts. I also ordered that on the 27th and it showed up 2 days later, so I was ready to get to it yesterday as soon as the Airflows arrived.
I did the living room 15K system in about and hour and 20 minutes w/ minimal issues like getting the 2 big bolts to line up again once the Airflow was inserted...no big deal though, and I feel real good knowing those bolts are torqued properly again to 50 pounds.
I then did the bedroom unit in about the same amount of time, basically due to one of the bolts fighting me to line up and thread properly, but again, no biggee and the job was complete.
I had no way to test airflow before and after other than just by "feel" with my hands at the vents, etc. But I am writing to let everyone know that these things work big time! My rig was about 75 degrees after finishing installation and then I cranked up both units. The airflow out of the vents was like a tornado compared to before, so right away I knew these things increased airflow as advertised. My single ceiling vent in the bathroom was closed and the airflow was so strong the air was making a screaming sound from the air being pushed through the closed vent so powerfully. That never happened before.
I could also tell immediately that the air coming out was much colder than before. So I turned off the bedroom unit and just tested with the living room. Normally, with only using my living room unit when the rig was at 74 or 75 degrees and putting the unit on High setting down to 48 degrees or so, it would still not be able to cool the room down more than just a degree or 2 on its own. So I always had to use both systems at the same time to get the living room to drop down to 68 to 70 degrees with both units on High cranked way down. That would usually take 15mins or so.
Well that's all changed now. I cranked the 15K down to just 55 on High and it dropped the living room temp down to 66 degrees in about 12 mins all on its own without using the bedroom unit!!!!
That proves it right there. When I ran both units on High they turned this place into an icebox in no time at all. I got it down to 63 degrees and was freezing my tail off, but that proved how much more strong and efficient the units are now with the Airflows installed.
People may think these are a little expensive...but the 10% discount certainly helped out. And also, I would estimate they will easily pay for themselves over time because I can already tell I won't be running my units as long anymore which will definitely decrease the monthly electricity bill.
Anyways...that was a quick, easy, painless modification that works amazingly well. This is how A/C units should now come from the factory. Slam dunk upgrade!!!
Just wanted to let everyone know how well these work. You do a terrific channel and I watch all time since finding it several months ago. Thanks again for this and all your other videos!
That's awesome!!! We hadn't even considered the electric savings for those on monthly or seasonal sites! So glad they're working well for you!
@@ChangingLanes yeah, since I'm in Tampa and have had to work from my RV full-time since the you know what happened, I've had to run the A/C's all day all summer long. Luckily, my RV park is full of nice big oak trees, so I'm totally shaded, but it's the humidity that gets ya down here ;-)
Wish I had found out about these things about 6 months ago, because I'm sure my monthly electric bill would have been greatly reduced. I think I'm averaging about 100 bucks a month or so, give or take maybe 10 to 12 bucks I guess. But I'm anticipating that to drop at least 10 to 15 per month thanks to this upgrade.
One other recent thing to note for anyone reading this. After the installation the other day, my living room unit started making a rattling vibration like a fast "ticking" sound when it would turn on. I put up with it for a couple days, and when I would push my hand up on the shroud or ceiling plate it still wouldn't stop ticking. So yesterday I took out the filter cover and filter on the side the ticking sound was coming from, and that exposed the big through-bolt on that corner of the unit. When I pushed up on the metal frame where that bolt was the ticking vibration would stop.
I only cranked those through-bolts to about 47 or 48 pounds with that Wheeler torque driver just to leave a little room for error. So I grabbed the driver and adjusted it to 50 pounds and gave that bolt a few cranks to 50 pounds and bingo...no more annoying ticking sound!!!
Luckily that particular bolt was the cause/cure of the vibration and I didn't have to remove the shroud to get at a bolt on the covered up side (towards the rear of the RV side).
So anyways...if anyone installs these and uses the torque driver for the big bolts (which I also highly recommend), and if you leave a little room for error under the 50 pound setting and then hear a bit of a vibration, try to isolate which bolt(s) that might need a pound or two more tightening and hopefully it will take care of the vibration.
The bedroom unit was also torqued to like 47/48 pounds but it has no vibration and even sounds a bit quieter than before this upgrade. I also still can't get over the amount of force both units have now. It's like a TORNADO in here now when they're both running, and they cool this thing down twice as fast as before.
Like I said before...they may seem kind of expensive...but for full-timers who want to reduce your electric bill and make these systems run more efficiently and COLDER, they will be worth the cost, because you will definitely reduce your electric bill each month and they will pay for themselves over time for sure.
THX for the PSA on torque wrenches. I calibrate them and a personal pet peeve is clicker torque wrenches not set to minimum. The internal spring develops a memory when kept compressed for long periods of time.
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.
👍
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
The outtakes show just how much work and prep goes into one of these reviews.
Thank you both for all your hard work that probably at times seems like play.
Safe travels and God Bless...
Thank you for the tip & the video! I ordered 1 & used your code & got a $25.50 discount!!!!
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.. !
Just learned about these. Thx for the vid and sharing the numbers. Did you notice any decrease in the sound levels from the ac running after installing the kit?
great video thanks just ordered the airflow. werner the v twin biker from vermont. you two are one of the best .
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.
It's a good concept and glad you put it out there. The problem with so many TH-cam videos is that they aren't planned well nor rehearsed enough. This could have been much more precise and less boring if you would have done in two third the time.
Installed yesterday and let me tell you! WOW!! Turned on the ac after install and it blew out so much construction debris from all the vents. 100% worth it. For reference I have two Coleman Mach 15 Air-conditioners on a Arctic Wolf 3770 Suite 43 foot. Thanks for the 15% off too !!
Air Conditioning performance is all about air flow. Great product!
Recently installed in our GD Solitude 390RK and had a few 90+ days to check it out. I felt cool air flow in areas I hadn't felt before. Totally awesome they work great !
Great to hear!
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/
I am a air-conditioning contractor and I think that’s an awesome set up but the price is a little bit steep usually if you wait a while it might come down hopefully specially maybe towards the summer
A "little"bit steep?!!
Hey guys, thank you for the RV Airflow video. I just received mine today and worked for hours installing it. Where the Manufacture framed in the opening in the roof it was LESS than perfect! Not square, Unit not set on roof square, duct with large gaps, opening too small for main piece...etc. After watching your video, It prepared me for some of these obstacles. My rig is a 2018 Avenger by Forest River. To give you an idea how poorly it was installed my average increase is 61%...a noticeable difference. Thank you again for the excellent videos and information!
👍👍
Thank you guys, used the promo code and it worked great. Cannot wait to install it. Your video sold me on this product as I knew the way these were set up made them inefficient and killed airflow out of the vents. Thanks again!
Great video! I put them in our 2021 Momentum 397TH and love the difference. Confession, I put them in the bedroom and main A/C back in August. I finally got around to doing the garage last Saturday.
For anyone wondering the kits are $170 plus S&H
Yeah this is real nice. Starting to see videos where people are making there own and they are saving so much money making there own whole made ones.
What about installing a Mini-Split unit ? I know their will be a lot of things to figure out.
You could install the outside unit on the RV rear bumper. Since its DC it could run right off your batteries.
After starting up the unit should pull around 600 watts. These Mini-Split have a rather great efficient rating.
Also they are much quitter than the factory installed units. They could be installed directly into the RV.
No more possible leak from being on top. Just a few things that I was kicking around. I know it would be
a lot of work first installation but wow.
NOTE! Our AC is an AirXcel / Coleman and that's what's currently available for RVAirFlow. However, they are working on models for other units also, so keep an eye on their website! 👍🏼
Also... This is only for RVs with ducted systems.
@@CartersTrail In the video they installed one in the bedroom and when talking about the numbers they go over the improvement of all 3... did you watch til the end or ?
Can you send me your discount code so when the Dometic is available the code can be used
Awesome! Thanks. Considering all the money I’ve spent $170 is nothing for that much more efficient system.
I had one installed this weekend in our Imagine at the Grand Design Texas un-Rally and it improved our airflow by 30-48% across the 6 vents. We already had the Wacko RV AC Silencer and it is compatible with that product and decreased the decibel level a little bit as well. Thanks to Richard Stark and the RV Airflow team for this product. It will help during the hot Summer days in South Texas.
Hi Darryl and thank you.
We put these in our Solitude 310GK, and supplemented it with the "RV AC Silencer" from "WackO Products". This definitely improved air flow, but also brought the fan noise down to where we don't have to adjust volumes on the TV. While you can still hear it, it really doesn't interrupt the "vibe" of the camper anymore. I'd love to see you guys put these silencers in and measure any decrease/increase in air flow and nose levels! On top of this, it does completely eliminate the air dumps.
We need to try the silencer thing! 👍🏼
This system worked well in my Thor ACE but took some whittling /shaving and hole relocation. But the results were awesome major difference in airflow.
These are legit! Thank you! Our AC works so much better now!
Wow, I’ll have to try this. 40% improvement in air flow! That’s awesome! Thanks you all. Loving it as always. 😁Spoiler alert!😎
We’ve sold our RV but still enjoy your videos.
Awesome job, very straight forward video on the installation. I am a HVAC guy and am totally impressed. We also have a Momentum with 3 units, living mostly in Texas and that will really help.
I have found that after the unit sits for a day you should retightened all bolts as the foam gasket compresses. Don’t want leaks. Thanks for the information
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!
Chad did an excellent job explaining how this all works.
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
One of your best videos guys. Really have learned more from your videos than any others online. Thanks,
Ah, thanks!
Thank you! I watched your installation video and had my AC ready to go when the package arrived. I had it installed in about 40 minutes. The only problem I had was sliding the foam into place because it was very tight around the plastic duct inserts. Mixed up some dish washing liquid, put a light coating on both the foam and the inserts and it just slid right in. Perfect! Buttoned it up and ready for the big test.
I have a wind meter and before the install I measured between 7 -9 mph at both ends of my trailer from the ceiling vents. After the install I measured between 18 and 21mph! So breezy it blew the install sheet right off the table! Now my wife is worried it will be getting too cold in the trailer with the AC on.
My RV is a 30 foot Starcraft Autumn Ridge 266RKS travel trailer with a 15k Coleman Air Conditioner. Can’t wait for the summer heat to really try it out. Used your discount code and saved a few bucks. Love watching all of your videos!
