Gonna use this info and I'm looking forward to more videos, thank you so much!

I am so lucky to have been introduced to you through Alyssa!!! Nice to meet you Brock!!! I'll be needing one sooon! Your videos are priceless!!!!

Inspired by your clear, concise description and instructions. Thanks for your sharing!

thank you for the excellent install video. i'm installing a Bosch into a school bus and your walk-thru helped the planning, enormously. again thank you for the clear, well-shot and smoothly-edited install sequences. you provide just enough technical detail to give a handy person the necessary confidence to proceed, and a non-handy amateur the information that the install is likely beyond their skillset. thank you, -C

Thank you Chuck! Very good video.

Thank so much... you always post an interesting and informative video.

Great video dude! I'm glad I did mine before I finished the walls, I can see how that probably added a day. I was planning on running a circuit, running wire, and cutting holes, maybe even pre- running a lineset and drain hose to make adding a second unit down the line a little easier, but lately I've been Leaning towards getting the second one now... it adds 2 days and we really want to be on the road already so... I dunno

Great video. I love the way that you explain each step in a way that I can understand it, but you also give the technical stuff so that I can gain more knowledge as I proceed with different projects on my short bus. Thanks again.... this will be helpful to me when I get ready for AC next season. Take care Mr. Cassidy 🙂!!

If you cut the insulation, make sure you seal it back up with a vapor tight tape. That prevents air from getting to the tubing and sweating. - HVAC guy.

I am stuck with mini split install, this video is timing perfect. Though I must admit I’m not sure I’m brave enough to do it myself. If I don’t have it done by the time I get to Taos I’ll connect. 😁👍🏻

Excellent instructional video

Infinite thanks Chuck, this is saving our lives including my cat! I've been doing the research and realizing for AC as well as heat, this is the best option. Thank you thank you thank you!

I'm really impressed with all your skills you're the best I've seen on KZfaq thanks for your videos I just sent you a message about suggestions for my truck camper and I don't know if you're keeping your shop or whatever but I would love to stop by and meet you sometime I'm usually in Colorado at least once in the summer traveling out west and if it would be possible to get you to do some additions to my solar setup

Marie from Denver . Thanks for sharing!! 👀🔧🔨🔩🚃

Great show.

I love your videos. At first I was thinking no way I'm watching all 40 minutes of an AC install. But I did. Interesting and full to the brim with great info and expert tips! Another great video! This is the only place you need to come for expert skoolie advice!

Thanks Charlie!

Thanks Chuck.

Great video, I learned alot , also I learned I don't have to break the bank.

It isn't a home without sweet sweet air con!! I did HVACR commercially for three years before starting my bus conversion in 2018! We mounted our unit under the bus and these are SOME OF THE MISTAKES I made; I did not make a removable access in the expanded metal in order to clean the coils well (very important under the bus) I added a traditional dryer/filter which is a minisplit no no! Location of interior unit, We need fans to circulate air all the way to the back. I did not utilize both drain lines so my unit is tilted like a noob! Great video!

Just received my second replacement Pioneer interior unit as the first two developed leaks in the coils after about 8 months each. Thanks goodness for the 5 year warranty! Doing it again I'd definitely choose a different brand. Going cheap on the hardware has cost me more in repairs and water damage than I saved over other more expensive brands.

Great stuff bro.

thks for sharing Chuck..

I was curious if blocking the marker lights is a big deal. Thank you for answering that.

Very cool that you used Pioneer, Chuck! I bought four, put two in my house and two in my son's last year. They work great! Nice people at Parker-Davis. Good pricing. Great choice. That's trick that you put it on a mobile rig! I had to watch this. No reason not to, but it's not something I expected to see. I think it's really smart, out of the box thinking. As long as mobility-induced shocks and vibrations don't take a toll. But these rigs probably don't spend much time rolling anyway. I made all the connections at the indoor unit first, on a bench in front of the penetration hole (in which I used 3" PVC), wrapped it and fed it all through, then made up for length and slack outside where there's more room and it's less critical. Kinda like how you did with that heater where you attached the lines before feeding them all through the floor. I don't know why, but the 120 Vac versions have a cost premium over the 208/240 equivalents. The incoming AC is rectified to DC to feed the motor controllers and circuitry in both versions so there isn't much componentry difference, at least not theoretically. Maybe it's an inventory inconvenience kinda charge. But being an electronics designer, I know they could make a universal input that would work on both, if they wanted to. Anyway, it was just as easy for me to wire them up 240 at home, so that was a no-brainer. I left them overnight when checking for leaks with the vacuum. Then when checking for leaks with the lines charged up, I ran them up to about 75 PSI which is about five atmospheres, or five times the pressure differential of the vacuum. On my first couple, I even checked all my joints with soapy water. With all other HVAC installations prior to these, I've brazed all the joints, so I was a little leery of these flare joints. None leaked, but I do suspect they could be a point of future leakage over time. I keep thinking I should go back and double check their tightness and check for leakage with soapy water. We'll see... Cheers!

Pioneer makes excellent products. I installed a 24k unit in my shop. Love it.

Good video thank you

Very well done info commercial. 👍👍👍

Would love to see a video of you mounting it under the bus. That's where mine is going. Also can I mount my solar batteries under the bus against the frame to save space?

Chuck, thanks so much for the pro's way to do a DIY AC! I put the Pioneer 12k in my rig in 2018, and would have killed for a video like this. Turned out way purdier than mine, but I'm starting a new project soon, so I will have a second chance at it. I actually bought a pipe bender because my install location was a bit more complex. Unit has run flawlessly for 4 years now. Love all your videos, you are an excellent teacher, would have loved shoulder time with you on some projects, I am a visual learner. Thanks again for all you do for our community.

You do such amazing work buddy, well detailed 👌 I’d like your help in completing my conversion

Classic Charlie loved the video brother Pioneer is the best I wouldn't use abutting less Charlie I have a question you mentioned some of the upgrades your helping with the DC to DC charger you showed is a 12 volt unit or did I hear that wrong? Because you said it would charge up the server rack batteries he's using but they are 24 volts you mentioned just wondering I have a 24 volt system and wondered what the specs are on the DC to DC charger. Thanks bud.

I used this video to install my mini split today, this was a great guide so thank you chuck, id like to note its a pain in the @$$ when you get to the very end and go to pull a vacuum on the outside unit and realize your gauge set kit hose fittings you ordered on Amazon are the wrong size so you have to order and wait for an adaptor to come in the mail. as chuck would say its a real bummer..and also I only flared my copper lines 3 times and forgot to put my flare fittings on first. boy I felt dumb all three times.

I have a Pioneer mini split with a Ceiling Cassette and it has worked well for years now. mine is in a a ADU apartment but with that being sail I think, That system with the ceiling cassette would work great. especially in a new build or even as a retro fit for roof mounted AC units. Just a thought. keep up the quality and have fun. OH and what would you think of some rubber lines like are used by the auto industry for some of the troublesome areas.

I didn't realize that Pioneer was a DIY... I had planned on going with MrCool for that reason.

Perfect timing. I ordered that mini split just the other day. The brackets that you fabricated, is there a structural element that you’re bolting to in this video? Are there structural members there. I have yet to cut that piece out of the bus. Great video. Thank you!!

two questions - 1, have you considered using flex lines and if not, why? 2, any concerns about the outside unit covering the clearance lights?

Thanks for showing us an A to Z assembly! I got wondering... Does the outside unit has rubber feet to absorb vibration?

I hope you moved the 3 dot lights from behind the unit that is a hefty fine if they’re blocked

Fantastic video as always! The only question I would have is with all the vibrations of a bus and the outside unit all the way at the back, are the feet of the exterior unit really enough to hold it on for thousands of (sometimes rough) driving? I'm sure they are because you did this and I trust you, but if it were me, I'd probably add a bracket to the top to keep everything safe. Would that just be overkill? Thanks for the awesome video!

Make sure to cover it up with a removable cover so it doesn't get damaged with wind from driving . The fan can't take super high winds

Chuck I’ve heard a lot of commentary about mini splits becoming obsolete with advances in tech in RV style units. What’re your thoughts on the RV units? I ask because I recently bought a bus with a $900 senville installed and the builder did a hack job with it and now I’ve gotta hire someone to come charge it. They mounted it on the side without much ventilation and no conduit and it’s just turning into more trouble than it’s worth to rectify. I’m currently debating removing the side mounted condenser and relocating it to where you put the one here or scrapping it all together and going with an RV style rooftop unit. I’d really appreciate your thoughts on this

check out the new LG inverter window units. They are just as efficient now, it's amazing

Amazing video once again. You don't miss! Question. How does the energy consumption of this Mini split type unit compare to a rooftop 12v Dometic 2000 RTX? The Dometic ranges from 19-58 Amps. Not sure about these.

awesome vid, thanks! btw...yomiyuri fan?

We have a deck on the top of our schoolie and want to replace the boards. They are currently 2x6-treated lumber. My wife is thinking of using composite decking. Are there any stress or other factors inhibiting composite vs wood? BTW: Excellent presentation. Thank you.

How well does it cool the front area of the bus if it is all the way in back? Do you need some sort of circulation fan to keep the temp balanced? Can you add more than one inside unit to the outside unit, or would it be necessary?

Do you worry about wind while driving, over reviving or back driving the fan? Can you run the unit while driving?

I'm presently installing a Pioneer 12K in my bus. I've put the outdoor unit directly above the front axle (my bus is a pusher, so no driveshaft there), where it gets all the cool air it needs while driving as well as when parked, and because it's between but not behind the front wheels there's no risk of stones or road debris hitting the A/C unit, plus it's protected from rain. I had wanted a 16-foot lineset, but Parker shipped a 25-foot lineset instead, so I'll need to cut and flare the lines down to a better length; I'm worried that there may be barely sufficient refrigerant in it now for 25-foot lines. R410a is soon going to be replaced because of its environmental danger, so I bought a small can of it today to keep as spare if/when I ever need to top up the refrigerant in the future when it will be no longer available. I'll be powering the A/C from my 2000W Magnum inverter, so I just can't run any other big loads while the A/C is running! I'm curious how much warmth the heat pump will produce in the winter, but I also have two very effective diesel air heaters if it's insufficient.

What size mini split (BTUs) would you recommend for an 11-window bus (4 windows blanked) with 2-inch spray foam walls and ceiling and 4” rigid foam floor insulation? I want to be comfortable in the US desert southwest in summertime for vacations.

Question: When you hung the outside unit what did you attach the bracket to? Did you just run bolts through the skin of the bus? Did you use a brace on the back side of the bracket?

Chuck, I'm interested in purchasing a full off-grid solar system from you. Where can I submit my request for this and get a quote from you? Thank you!

The out door unit blocks the center tail light. Does it still meet DOT requirements? I’m thinking about installing the mini split same way as you did, if it can pass DOT. Btw, great video, thanks

Hey Chuck! What is the 12 to 24v DC to DC charger used here? Thanks!

Maybe not for your show, I have a shuttle bus. It has AC that needs freon. And a second one I'm told only needs to be hooked up to electrical. I'm also told that a mini-split A/C heater uses less power. Considering the bus is for off-grid life, Should I remove the second A/C(hanging in the back) that came with the bus to gain less weight for better gas mileage, less draw on batteries, and buy a lighter more efficient mini-split? Would that be worth the time and trouble? My mechanic says I wouldn't get that much more in mpg.

Excellent DIY vid! The Half inch nipple for the electrical box is too small for the 12awg and unit’s electrical wires. 3/4” works better. Would have like that installation in the vid instead of glossing over it. Then how you selected your breaker for it. Did you need a 20amp or 25amp breaker for the 12,000 btu. I’m installing a 9K btu and I’m using a 15amp do you recommend going to 20a instead. Thanks appreciate all you do!

Chuck, great diy video. My question is the line set length? The factory says 10" minimum length to avoid damaging the unit. Your instal is less and you've done several instals. Any issues so far and are you worried about voiding the warranty? Thanks in advance.

so the DC options (nomadic, cruisencomfort) are 5 times as expensive but claim to be twice as efficient, what kind of draw do you see from these in your builds in summer heat?

Where does the drain hose go thanks

40:11 Apes and dogs, living together! And the dogs make the apes yell "shut up" and it's on YT forever. I'm probably on at least a dozen. 😂

Hey this might be an odd question but I was looking at Pioneer's site while in the intro and only saw a 115 and 230 volt models. Did you mean to say 115v and not 120v? Thanks for all the great videos and info.

Could you not run the condensate to a collection take?

I wish we had 20% humidity at 90! We've been at 110° and 60% humidity, this is crazy!

Chuck, did you add any AC vibration pads on this condenser unit? Between road travel and having that unit so close to the bed, might it help the noise factor (and maybe unit longevity)?

Looks like the outside unit is blocking the top 3 marker lights above rear door. No issue with DOT by blocking those?

I’m doing something similar I’m gonna use lithium batteries but idk how many I will need.

Silly question, does the drain just drip under the bus or is it connected to something?

Im looking to do this to my bus. Iv never done a inverter setup and wpuld love a simple setup. But i need a more bang for your buck kind of setup. I mean i got the bus for 200$ and swapped in a dt466 that i got for 600 haha. I already know with some of this ill have to drop a pretty penny. But im about to get it sprayfoamed and then spit unit. And solar

Hi, question: Is a Mini Split a heat pump? I see some mini splits that seem to be standard compressor AC units with the condenser and evaporator separate.

Are worried at all about blocking the rear marker lights at the top of the bus? Highway code states that if your vehicle is over 80 inches wide or 30 feet long you must have marker lights visible.

I'm in the early stages and you are my go-to on several fronts. I just bought a shuttle bus that has a humongous AC. It must take up 30% of the roof. And the internal unit... Inches inches on top of inches. First question, will the 9000 BTU be sufficient for a 25' shuttle that has a very open floor plan? If the exterior unit is placed underneath the bus how much space is needed from the base of the unit to the ground? Lastly, I would prefer to put this in the middle on my Transit. Bedroom is in the rear, not fond of cold wind. Any issues in particular with a mid bus placement? Other question relates to insulation. I watch the insulation videos. After I take out my headliner and my rubber floor, might have about 6' 3". I can't give up 6 in to insulation, the substrates, then still stand. When I lose a lot by going to inches on the floor and then spray the roof? What are your thoughts on heated floors? Again, thank you.

Can I ask what model that dc to dc charger was? Thanks 🙏

"Bogarting" hmmm. Got it! LOL

I know you pretty much do schoolies but do you think your rear mount will work for a Class A RV?

Does that mini split have a dc compressor

chuck im freezing here in florida in the middle of the night what can i do it turns 51 but feels like 35 in the dragon ice box uggggg help

Do those brackets hold the unit in place on a bumpy road?

Love your channel, not trying to attack you or anything, but is there a reason the indoor unit isn't centered? It's shifted to the right about 5 inches. I noticed when you put the template up, it's driving my ocd crazy!

As far as cooling, how does it compare to a rooftop 13.5 dometic unit

Pioneer has 2 different 12k btu units, both around the same price. The “dimante” , and the other. Do you recommend one over the other?

I’ve heard about soft start electronics for the mini split. Are these worth it?

Where did you get the single vacuum gauge?

I'll have to run a 20amp wire and breaker.

How much do you charge to install these and where are you located?

That charger is the BB122470 right?

Was that victron inverter 24v or 12v?

Sweet l saw it in time but seems like l missed a bunch.

Are those batteries available in Canada?

what about 12 volt and 24 volt truck units for smaller vans. I was looking at a 7m (x2.4mx2.5m) freezer van and i found the insulation (4in sandwich) is rated at 0.37W/sqm. which equates to.. if its 45C outside and 22C inside the heat loss is just on 200 watts. A 1kw pump unit would kill it.. at 3x efficiency, thats 300 watts for 1/5 the time running. 60 watts. 12V, 5A for 24 hrs 150 A/Hr of battery. Ok 60 watts for 24hrs = 1440 watts /6 hours solar = 240 watts of panels. YES winner. A 7m box body has room for 7x400watt panels. AU$350 second hand.

Does this fall under Pioneer’s basic or standard warranty when installed like this? Or is the warranty voided?

Does anyone know who makes pioneer? The condenser looks like a Gree to me I'm just curious about it

I tried the website you mentioned and it says your website is no longer available

What size solar panels would you need

Only 4 screws to anchor the outdoor unit to the cage? And only 4 screws to attach the cage to the top/back end of the bus? How much does that unit wobble when driving down rough roads or uneven terrain?

Ooooops! You blocked the middle clearance lights. I'm wondering if you added a fix for that.

I have a Coleman mach AC unit in my ceiling on a ambulance 🚑. Only works when plugged into shore power 🔌. I'd like to go with a mini-split... but, can it run on solar? I have 400w on the roof and 2 100w lithium batteries, 40A MPPT, DC to DC charge controller and 3,000w pure sine wave inverter. My brain hurts trying to figure these things out.🤯

Edit: Nevermind! I feel dumb; I'm pretty sure I already have a pair of those Carhartts 😂. __ 👀 What brand are those shorts? I want them. Love when they have the knife reinforcement on the pocket. I want the brand because the color is important to me lol

I have a question and I’ve always heard the only dumb question is the one you don’t ask. Can you run the mini split and cool the bus while you’re driving?

I went on your link pioneer website, why do some have DC inverter option. What is the purpose of that function? Thanks great vid.

Was that Jax Austin's old bus ??? Hope he's ok.
