A $10 DIY solution to Improve Our RV's Air Flow System For More Cold Air!

Is your RV Air Flow lacking? In the middle of the day is your RV still hot when the RV A/C is running full blast? We have 2 A/C units on our new coach and it never really seemed to be any cooler than when we had just one A/C units.
I found out that we had an RV Air Flow issue! Our A/C was not really blowing air into the duct system. Something had to be changed in our RV's Air Flow system!
With a little time, creativity and some ridged foam I crafted and simple solution to the RV's AC airflow system.
Come along with me as I walk you through this simple 30$ DIY RV air flow improvement. .

Retired Mechanical Engineer here in Houston area, you are spot on with modifications made. Your simple but effective design accommodates intake and exhaust flows, well done. I purchased the material and will be installing soon. Thank You.

[@DudeRV]

Wow, thanks! Very welcome! thanks for watching!

[@felipevazquez123]

We replaced an old Dometic in our 36 foot camper (vented). kzbin.infoUgkxDDbPbIlwLRcX_ntp51ui5UMtAUGpHYxE The install was a simple swap, all holes lined up, the electric plug back in with no trouble. Getting it on the camper was the most "difficult" part of it, and my friend made it look easy. I've seen people "sled" them up ladders as well though. I watched a KZbin video for instructions, very easily done. Some say it doesn't come with instructions, but I found the instructions under the ac in the box. I didn't need them, but they were there.It works well to keep a 36 footer comfortable, all by itself. It doesn't seem to be any quieter than the original, but it isn't any louder either. We're very pleased with it. Esp with the ease of swapping them out.

My daughters camper was icing up and it was due to poor air flow. It was a mess. Than I saw your video and got some foam and fixed mine up!!! Amazing difference it made after adding the foam to seal things up. Wish I had a wind speed meter to do a before and after. Plus at the end of both runs I blocked off the duct after the vent so no more wasted air flow traveling past the last vent.

[@dandurig8181]

Worked well on 100 degree day. I only have the 1 AC and it kept up great. Before if I closed the dump vents the compressor would just freeze up. I wanted to buy the single foam unit to do this but it was expensive if it didn't work and I didnt want to risk that much. This fit my budget to try and worked to boot. I liked the extra return space as I have had filter problems previously. I also found an uncut piece of roof material blocking the airflow some as well. Great video and thanks for sharing! One additional note on the dual straight track roof vs u shape track is make sure ends are blocked a few inches after the last vent to get more equalized pressure on all. Bocking AT the vent will result in higher air flow for that one vent but lower for others. Sometimes the factory doesn't even seal them so check!

The manufactures are well aware that factory quality control is sub-par.

[@jboxjbox]

I have been battling this Texas heat and humidity struggling to keep it cool in our travel trailer in the heat of the day. I have been thinking something was wrong with the design every time I clean my filters and see that it’s primarily only one side collecting dust. Seems pretty inefficient to me and I like how you modified the airflow in yours to take advantage of the entire intake and push more air from the ducts to spread it around. Thanks for really going into explaining the design as well. As a guy fascinated with the “why?” it helped a lot. Much appreciated. You earned my sub.

[@DudeRV]

Thanks for the sub!! I am glad you found this video to be helpful! It really is a game changer when the temps and the humidity are maxing out. Did you see the Soft Start video I released a few weeks ago? When it is really hot and everyone is running their A/C at max the brown out will reduce your A/C output. With an RVSoftStart system your A/C requires less power and is therefore less effected by the brow out. here is that video.... kzbin.info/www/bejne/jWLCdamdqphqq5Y Hope this help and thanks so much for watching!

I can't wait to fix it for him, I appreciate you showing me the way. I read in the comments that the vent ports have the same gap issues in the ceiling, have you done a video about those too? I will take one apart and check it out. My wife and her mother and I rented a bigger class c and took it to Springfield and Shelbyville and back home. It was honestly one of our favorite road trips just for having all of our conveniences with us like a kitchen and bathroom and a couch and a bed, it's like traveling in your house. The passengers can watch tv or sleep comfortably in a bed or stretch out on a couch and read or make lunch...even the dogs are welcome! That alone is enough for me lol. We stayed at a campground in Shelbyville that seemed like a great group of people and tons of things to do. We've wanted to buy something for a long time but currently we don't have space to park it.

@@michaelosmon I was happy with the fogged lens for that exact reason! Yappy gets a lot of credit for what we have, when I was really sick she carried the load and became the primary provider. As for the vent issue, our ducts are basically just channels in the Styrofoam roof and the vents just snap into the roof covering. to improve on this set up I would have to completely remove the ceiling and that is not a simple project. You will blow your friends mind when you show him this simple solution!

My new Thor Challenger 2021 is just like yours before you modified it. I park at 3, and the temp inside is 95 in the back (My Generator shuts off without a reason) and it takes from 3 til about 8pm to get to 85 degrees. I also live in Texas. Mines in the shop now for 3 other reasons but as soon as i get it back (in a month or so) I'm going to do this DYI. I'll use my power tools and be at my house so - without all the sweating.... I Like your attitude. The "DUMP" setting lets the cold air out right next to in huge return, so my theory is that what little cold air I get, goes right back in the intake. I thought the ducts sucked. The dribble air out, but I don't have the air meter. I'm a engineer, (I was - now I just golf). Your insight on a 4" x 5" air duct blowing into a 5"x 1" plenum is dead on. That air wouild have to go to 4x atmospheric pressure to get out that plenum. You just can't squeeze the air molecules closer together without some other impact. (Bernoulle did the math). So the idiots at Coleman and Thor came up with a pretty, but worthless design. Your mods bring it back to close. The two duct opening looked abouit 5" X 2" so that woiuld imply a constant pressure transfer. The issue of turbulance may hurt a bit, but far less than the original design. The "after action" report you gave was excellent. In 30 minutes you cooled. your RV. It woiuld be good to know if you ran your Generator and AC's and what the starting temp was when you docked. Thanks for the info.

[@DudeRV]

Your most welcome for the info! I did not run the A/C units before I "docked". I have found that the whole system cools so much better overall since I did this mod. I have since installed soft start units on both A/C units and are pulling less power overall. I really appreciate your comment and even more I am grateful that you stopped by and watched!

In my book, ugly is OK if you are getting more cold air! GOOD JOB! and thanks for watching!

[@frankperry1543]

I started to do the same your our units earlier this week. Our covers are a split style, so you can uncover the outlet and inlet separately. Anyways, I had just the outlet side off, and because I was curious, I turned the unit on. WOW! It blows like a tornado and it makes about half the noise. Anyways, I stopped right there. I may go back later and actually close off the opening to the ducts so that all the air just dumps in one spot.

[@DudeRV]

That is great! You might check the intake side just to be sure there is no obstruction in the way. thanks for watching!

Hello Dude RV, it's funny l didn't see your video until today August 13, and l did the same modification on my ac unit last week. Pretty much identical. I have the same Coleman Mach you have the only thing l did differently was l rotated my grill 180 and now l can look straight up into my return and there is a larger area for air to flow straight up. I haven't tried my ac yet, due to where my camper is parked but I'm sure it's going to be a lot more efficient. Anyway thanks for your input. It's nice to see someone else with the same idea.

[@johnmaida160]

Hey! I took my A/C cover off to see if it was the same inside as yours. Turns out the manufacturer used an entire can of spray foam insulation to put the unit in! Almost all of the return was clogged with hardened foam! SO glad I looked, I could have burnt out my unit. Took me an hour, but I cut most of it away. Next step, make your baffle. Thanks again!

[@DudeRV]

It is a good thing that you found that! You will love all the cold air once you have the baffle in place! thanks for watching!

[@kennydavidson417]

My fellow vet. I really enjoyed watching. I really liked your design and much better then others, that I’ve done to 1 of mine. I’ve got 2 Dometics in my ‘15 Montana 3160RL. I noticed a mistake I thought they may have done and didn’t know until I’ve done it and actually seen and experiencing. The reduction of the Return AirFlow area in size. Mistake made I didn’t catch and thought about after doing where you actually confirmed my thoughts. Being a electrician and seeing ACs being installed in construction as well as having some training on ACs when working offshore. Therefore I’m redoing mine today as well as my vents. They’re sealing is terrible in the ceiling. I am curious do you have the “RaceTrack” Ductwork with your 2 units or the “HorseShoe” Ductwork? I have the complete circle closed loop “RaceTrack” with the 2 Dometics having the 2 ducts on each side. I’ve noticed both Blowers turn opposite directions on mine. That also I guess in RVs the setup is called a “Zoned” System. Don’t understand that, because unlike residential or commercial. There is no electrically energized gates to stop and redirect the airflow to another zone. Did investigate into the “Zone” of RVs and the way I see it is that both ACs run per say except they only operate at certain times. Example 1 runs for 12hrs. then other runs 12hrs. when Zone1 shuts off at whatever time you program into the Thermostat. Then Zone2 takes its turn. So best I can say it in my opinion is to make it look like you’ve got 2 ACs working as 1 AC to be more electrically power efficient. I live in my 5th wheel and ouch my light bill here in South East Texas is getting up there. Since mine is a complete circle and blowers run in opposite directions Living Room blows right and Bed Room blows right. Also since the ones the manufacturers make is styrofoam and actually round curves redirecting air flow into vents with no resistance, but blowing the cold air into both ducts through the vents straight into the other AC. While that AC is doing the exact thing. Also if they’re running at the same time, yes would be serious airflow. Wouldn’t it also end up giving more airflow in the middle between the units? Making the middle vents cooler and blow hotter, tell eventually possibly building up enough resistance to back flow it into the other vents? I was thinking of taking a block of styrofoam or glue pieces together and creating a combination of both designs that as the 1 blower turned right to channel that air into the right duct up to the AC turning left. Then channeling or tunneling if you will to from the duct it’s being blowed in from the other AC and tying it into the same round curved tunnel from that blower turning left. Now while it’s pulling in the cold airflow from the other AC its also pulling in the air from like normal and pushing both airflow sources the airflow from the other unit and now it’s own air into and through the ductwork through the vents back into the other AC unit which it’s styrofoam was made the same way. Basically it’s a tunnel from one duct straight through the supply side space into the other. Also having the whole 5 1/2” blower opening intake tunneled downward and curving into the left side or right side duct, which ever way the blower blows. Being careful not to close off the tunnel that’s coming from the other side duct. Kinda like drawing a arrow in a R or L direct but instead of having 2 blades 1 up and 1 down. You only have 1 blade at the top. I would believe that is actually why it was called the “RaceTrack” blows fast and hard in one direction in my case to the left like a RacTrack with no restrictions. Of obviously having everything in the AC system ductwork sealed with supply and return as well as the units have proper flow of air in and especially out to dissipate the heat created during the process of exchange. What you think, in your opinion would it work in reality not just in theory

[@DudeRV]

Your theory sounds workable, but the only way we will know is to have it done and test, test and test some more. I am not sure if my ducts connect anywhere but at the input from the units. Our A/C system has 2 zones with one thermister (thermostat sensor) and one 13.5 unit making up a zone, there is nothing controlling or separating the two zones. Keep us posted on your racetrack mod and thanks for watching!
