How To Make Your RV AC More Efficient | Cheap RV AC Mod

[@matthewsmith1460]

The fact that you mentioned your son in the bunk area, noting that he will finally have more air, that is awesome. To many so called dads out there that don’t think of their kids and just themselves. You are great, and I hope your kids recognize it. Great job

[@JouppiOutdoors]

Thank you for the kind words and thanks for watching!

I did this mod last year. What a difference! The A/C unit is much quieter and it puts out much colder air! When I did this mod, I found that the intake was clogged with wires! I moved them to the side and secured them with zip ties.. 45 minutes of work for a world of difference! I recommend this for everyone!

[@JouppiOutdoors]

It’s definitely a game changer! Just having everything sealed up would help a ton. Thanks for watching!

My husband sent me this link… I was able to do this modification by myself following your instructions. Huge improvement in air flow. As we head into 100+ degree weather this 4th of July weekend, this will be a lifesaver. Great clear instructions, anyone can do this!!! Thank you!

Nice work Bro, picking up out Motorhome this week, this will be the first Mod that I will do.

[@JouppiOutdoors]

It has helped our A/C efficiency quite a bit! Thanks for watching!

[@georgestevens3770]

It works.... rear ac pushes hard all the way to the kitchen vents...30' away.

[@JouppiOutdoors]

Awesome! I know it made a world of difference in our 5th wheel

[@vdubing01]

Should have left out that first plastic panel you put back in. It restricts the intake. Remove it for even more flow.

[@JouppiOutdoors]

I’ll check that out, thanks for sharing!

[@inmyimage1081]

interesting diy of that foam thing you can buy. will have to look into doing this for the bedroom ac but not sure i could do anything for the main one because we don’t have interior access to it.

[@JouppiOutdoors]

Thanks for watching!

[@Horsecraze555]

I have a 2004 Living Quarter Horse trailer, AC works fine I just need a new cover that is literally crumbling. Do you have any suggestions on replacing just the plastic cover?

[@JouppiOutdoors]

Unfortunately I do not.

[@donniemabry1470]

You ever do any tent camping ps I love watching your son fishing hope to see more fishing shows.

[@JouppiOutdoors]

We don’t tent camp these days, but we will definitely be adding in some fishing videos!

[@Weatherscapes]

great idea!!! May give this a try!

[@JouppiOutdoors]

It is a game changer! Wish I would have done it years ago!

[@timothybuchanan1611]

Do you think that half inch foam board would be strong enough to do this project?

[@JouppiOutdoors]

I would not recommend it due to the force of the air.

[@ChefBoiImHungry]

i achieved the same results using "FOAM CORE" poster board from my local dollar store and hvac tape for a fraction of the cost as the pink insulation board from the hardware store

[@JouppiOutdoors]

Nice! I’m sure that works just as good. The foam board I used was only $7 for a 2’ x 2’ piece so it wasn’t really expensive. Thanks for sharing!

[@timothybuchanan1611]

Do you think that the foam core poster board will be strong enough to withstand the air pressure and not bend?

[@timothybuchanan1611]

Did your method greatly reduce the noise of the air conditioner? I'm wondering if thicker material might be better at sound deadening.

[@JouppiOutdoors]

I don’t know, but there is quite a bit of force there. The foam board is really inexpensive so I would recommend using that.

[@ChefBoiImHungry]

@@timothybuchanan1611 12db reduction i used 2 layers of foam core then wrapped it in silver widow shade material i had in my trunk.... $4 window shade from family dollar

[@ryanvegas777]

Sorry, but after the cost of the foam board you’re only looking at maybe an extra $55 for the Kool RV premade max airflow kit. Not to mention you bet back 96.54321% of the time you spent with a near plug and play application. Excellent job though!! Had those kits not been out this is absolutely the fix! I’m just lazy

[@markanderson7267]

Go Tigers!

[@JouppiOutdoors]

Absolutely!

[@markainbinder6213]

You get more air introduced in 1 area. By completely blocking it you work the system harder. You can block half of it, not all.

[@JouppiOutdoors]

This doesn’t block anything, it simply provides a direct feed into the duct work to distribute the cool air more efficiently and evenly throughout the RV. Many manufacturers are now using an insert in the a/c to do this from the factory. Thanks for watching!

[@desertfresh3740]

Interesting...i have a Toy Hauler so removing the ability to open the vents directly sounds less than ideal but I'm willing to give it a go. The AC shouldn't struggle at 80° ambient temps...

[@JouppiOutdoors]

It definitely helps the overall efficiency. Both of our A/C’s would run non stop in Florida from about 10am till 9-10pm prior to this modification. Now the living room A/C actually cycles off and on throughout the day.

[@desertfresh3740]

@@JouppiOutdoors ah, I have a 26' (33 overall) with a single AC in the back.

[@Here-2-Learn]

So how’s the comparison?

[@JouppiOutdoors]

Well, it’s 97 degrees out right now and 74 inside. Prior to this we would struggle to stay under 80 with both A/C units running. I have also done this to the bedroom a/c. Definitely distributes the air more evenly throughout the 5th wheel.

[@jdog1297]

This WILL void the warranty....you can't adjust the air intake rate or the backflow pressure without taxing the blower motor...this will shorten the lifespan considerably.

[@JouppiOutdoors]

Thanks for the info, however…there is an insert available that is now being installed by many RV manufacturers that does exactly what this modification does. It is only directing the air into the ductwork of the trailer. If there is a question of warranty, I would recommend the consumer reach out to their RV manufacturer.

[@jdog1297]

@@JouppiOutdoors consdering I am a Dometic and Coleman dealer, i've never seen this 'insert' you are talking about. Every AC has the ability to just run through the ductwork, that's not what we're talking about here, what is happening here is restricting the intake and output air flow, which is inherently bad for the upper unit.

[@garyag45]

@@jdog1297. Check RV Airflow, 👍😎🇺🇸🦅

[@timothybuchanan1611]

​@@jdog1297Thanks for your expertise in this area. Can you explain how the input air has been restricted? Also, the only way I can see that the output air has been restricted is that you've sealed out all of the spots where air could leak out around the ceiling cover of the air conditioner. Is that where the output is being restricted or is there some other place as well. I look forward to your response.
