I Modified My RV's Air Conditioner to Run Colder & Quieter For ONLY $15 - The RV AC Mod Made Easy!
IMPROVE RV A/C Efficiency & Performance. This episode will show you step by step how to modify your A/C (air conditioner) plenum to increase cold air output and reduce noise. By building a series of baffles, this modification upgrade will increase the efficiency of how your RV A/C directs cold air into the ducts. The statistics mentioned at the beginning of the video are averages taken from a small group of our RV friends who had done this modification and reported their findings using a decibel meter and an air flow meter.

I built the baffle last week. It works perfect. I measured the air velocity at two vents with a Radio Shack wind speed meter. Before the modification I measured 6 mph at both vents. After the modification I measured 8-9 mph at both vents. That is more than 40% in line with what others have found with this modification. Thx for the great directions

You manage to show exactly where to work and what to do without skipping a step or getting your hands in the way so I can see what you are doing.

[@ritarolen7066]

FINALLY!!!!! Hubby and I watched your video on how to get the a/c in our travel trailer up to speed and man!!!! Best modification ever!! It took us about 4 hours and we taped up everything inside the box that the factory should have done. We didn’t have a measurement for the improvement but we took a quick 2 night trip at a local campground for a trial run. We were totally shocked at the difference. Our 30 ft camper has one a/c and it’s always been a struggle to camp in the summer in SC and surrounding areas. Well, that’s old news now. We had to keep raising the thermostat from our previous settings. Actually got a little chilly :) So excited about this project and so happy for your helpful advice. We always learn something from you. We’ve been camping for years but we always want to know more. Your channel is a great resource. Thanks again

I appreciate the kind comment John. I’ll be here as long as there is an audience. Thanks for watching!

[@user-qs3oc4nj5c]

Great video and even better modification. It’s easy enough that anyone can do it. When I opened my unit up, there were so many air leaks due to a poor installation at the factory. After I got mine done, it’s noticeably cooler and quieter. I live in Texas and normally don’t do anything here during the summer. With this mod, tinting the windows and adding reflectix over the windows, I was able to cool my RV from 92 (inside), 104 (outside) to 75 in about 90 minutes. Best part, was the whole RV was cool.

[@AndTodaysProjectIs]

Glad to hear this worked for a Texas family! I'll be doing it as well!

[@dustin6828]

I’m in Florida. If it’s 104* outside, it will be 120* inside. 30’ Jayco with one A/C can get it down to 80* in about 30 minutes. Anymore, I leave the thermostat at 78* and all is well. If I try to cool it down to 72*, it struggles significantly

[@georgefriedel8666]

I did this upgrade today but in addition I removed all 5 registers. These were all retapped. The two near the ends I built a dam to stop air passing register into dead space. In addition I cut some of the registers 1 1/2” mount height making it easier for cooler air to flow into them. A full days work for a retired guy but the flow is much much stronger and I believe will be way more efficient! Thx for the tip to get me started!

@@RVTIPSANDTRAVELS so what if you have a double side vent. So you’re saying you won’t need those anymore since the RV has the roof vents? I think I have 6 in my living and kitchen and then 1 upstairs and 2 in the bedroom. Bedroom stays very hot. Also I have 2 units. I just want to make sure if I do close them up it would be able to still push enough air out with them being closed.

I had installed a similar device (tepee) a couple of years ago, but it was not as sealed as this method. Today I used your method. Was hoping for more air flow and lower noise.

Since we have a different coach, if we do the rear a/c we will be using 1/2 foam board. We are in the high desert in Southern Utah. Outside temps have reached triple digits, but the inside of our Palazzo has not been higher than a comfortably dry 80 degrees! Noise level has been reduced, but not drastically.

[@RVTIPSANDTRAVELS]

[@greauxpete]

I had the steel divider with spot welds attaching it to the flat sheet metal mounting plate, but my fan discharge was not centered so I had to tweak the teepee from your layout slightly. I went a step further and insulated around the whole vent opening with reflectix bubble wrap and aluminum tape. The cooling capability is 100 times better. My bunk area is getting much more flow. Actually, all the vents have higher flow rates. I suspect cold air was getting sucked and pushed into the hot side. My system cools so much better that both the blower and compressor cycle on and off. Thanks for posting this.

[@dwyman1972]

Great idea. I purchased the rv air flow a couple of years ago also works GREAT, but costs way more. One other suggestion that I did, at the end of the duct work runs I put a piece of foam to block off any air leaks at the ends of the run. All of it helps a lot. Just wish the rv builders would insult the roof better. Keep up the good work.

Great mod and instructional! A little sneaky how your tape just appeared tho, that was rather labor intensive. I'm not a qualified handyman but neither am I a slouch. I put 7 hours in on the ac unit and 2 hours in on the vents(not described here, just remove the cylinders and tape the transition from duct to each vent) After finishing the ac unit I had 39% greater airflow and a 4db reduction in noise. After doing the vents, airflow improvement was upped to a full 50%! Recommended if you don't mind putting the time in.

Dude, this was incredible advice. I built mine today, took me less than an hour in total and i had to have doubled my airflow. My divider had fallen out of place so there was nothing separating the warm and cool sides. I’ve never heard my ac kick off and on until now. I think all in i spent maybe $30. Great video

[@RVTIPSANDTRAVELS]

Glad it helped!

[@thraknar3363]

My wife and I are going to try this with our two trailers. Hopefully we can start this weekend!

[@RVTIPSANDTRAVELS]

Good luck, ask questions if needed!

[@mtgetawaysAR]

Pull all a/c vents and seal the gap between ceiling and vent with a/c tape. We went with RV Airflow System. I'm a licensed a/c service technician. only loosing the dump vent is well worth it. Great job on self manufacturing kit.

[@RVTIPSANDTRAVELS]

Thank you sir, appreciate the kind comment.

[@chesterfulp3202]

Please add some before and after decibels this is one of the best mod videos I have seen. Need to reseal my roof acs and will install this mod. Great job on the video.

[@RVTIPSANDTRAVELS]

I didnt take measurements but the readings i gave at the beginning of the video were averages based off of 4 or 5 others that did it at the time I recorded this.

[@WALLOWINGBULLS]

Great Video

[@wayback1000]

This is a very good video!! I am currently working on my unit today. I didn’t take the metal off at all which has made it much more difficult to get my hands in there. I left the center metal piece in and filled in each triangle corner to make it a flat surface for the “divider”. Yeah, I’m doing it the hard way. I can’t use a 1” board for the base as the bottom of my duct work is almost flush, no 1” space! I’m going to try to build something out of some 3/16” cardboard fir the base and have the tepee mounted to that. Hope it works!!

[@RVTIPSANDTRAVELS]

Cardboard or styrofoam I’m sure will work just fine. Cover everything with the metal tape to keep the air cold. Good luck let me know if you have questions.

[@wayback1000]

@@RVTIPSANDTRAVELS wow, that was quick! Thanks so much!! I was just looking at the Wacko RV AC silencer I saw on another tube presenter. He only measured a 2 decibel difference, but said it was certainly less annoying. For almost $250, I’ll come up with something else if this doesn’t make it a little quieter. Noticed the Dynamat in your comments too.

[@wayback1000]

Finished today. I was unable to build the teepee with the metal plate still mounted. Traveling Thursday so didn’t want to do that now. I’ll do that another day. However, I taped everything imaginable and built the “down” sides. Sealed the bottom off. Much better flow through vents now, AND sound dropped 6 decibels!! Very pleased!! Thanks so much for posting a very clear, concise, and extremely informative video.

Great video, you might mention RV AirFlow. They make an upgrade to the tune of around 170.00 bucks but those who have them love em. I have the same unit you do and may do this mod. I live and camp in the Pacific Northwest so the heater gets a lot more use than the AC. I did seal mine better but nothing near what you did. I’m new to your channel and have enjoyed your videos so thanks.

[@RVTIPSANDTRAVELS]

Thanks William.

[@brittvaughn9447]

Isn't it basically doing the exact same thing? It's just a big ole piece of foam isn't it?

[@RVTIPSANDTRAVELS]

Basically the same thing. The mod costs $15, the prefab version is $170. Personally as a DIY'er, I wasn't interested in spending $170 on styrofoam for something I could build for less than 10% of the cost.

[@danielgabriel5539]

This is brilliant, thank you so much!

[@RVTIPSANDTRAVELS]

You're very welcome!

[@Hopefullymarried]

I recently did this mod to out MallardM26 and WOW!! The difference is felt instantly and the reduction in decibels is noticed too! All the areas of the tt have cool air flowing and everyone is much happier and relaxed during our summer use months! Now if only I can improve the flow for the furnace vents! 🤨🤔🤔

[@RVTIPSANDTRAVELS]

thanks for commenting Marcus... you just gave me an idea. Let me take a look at that 🤔 stay tuned.

[@marklortie4681]

Thank you im going to do mine 😊

[@RVTIPSANDTRAVELS]

let me know if you have any questions, good luck.

[@jerrywhite5392]

I just did this mod today on both of my dometic units and man what a difference. It cooled down my MH a lot faster. Going to see how long it takes to cool down in the heat of the day here in Las Vegas.

[@RVTIPSANDTRAVELS]

nice!

[@markphillips590]

THANKS FOR THE GREAT VIDEO - WORKS GREAT! Just made the change two weeks ago - went on a 5 day trip in still hot Texas (not today - 37 and brrr) and it was so much better. We did not have to turn on the Closed Captions when watching TV, could actually talk to each other, and all but one vent was blowing great; BLOWING STRONG IN THE BEDROOM. Certainly plan to open the vent cover to the vent that is not blowing well to determine the problem, and will examine all of the vents so just make sure everything is looking good. The jigsaw works great, just know that you may need a mask and may want to try to contain the particles - they get everywhere - and they cling; but they vac up too! THANKS AGAIN!

He just drives the truck. I do everything else. Although, I'm trying to get him to relinquish the driving to me so I don't have to depend on him. Thanks again for the great videos!

[@caseymiklosh5537]

Just did this to my camper 20 minutes ago. What a difference. It’s crazy now much the factory metal wall bracket blocks the vent intakes. The ac is much quieter now and it blows way harder. It sucks in alot more air now too. Very curious to see how well it works with the Florida heat.

[@RVTIPSANDTRAVELS]

nice!

[@jeffallum5375]

I went to do this mod on my 2022 Imagine 2670MK, and I guess Grand Design has been watching you.!My AC has had this partially done at the factory! There's a divider between the hot and cold, and a bit of a slope forcing the air into the ventilation. Great video though. You're easy to follow and enyoyble to watch.

[@RVTIPSANDTRAVELS]

Thank you Jeff, really appreciate that.
