I Still Hate Mitsubishi: The Return Trip

- เผยแพร่เมื่อ 28 ก.ย. 2024
- I still hate Mitsubishi the return trip is the second part where I return to make the repairs I found three months prior. In the comment section of that video viewer, said that I miss diagnosed the evaporator coils as leaking, but the flare fittings were likely what's leaking, well, I guess you'll have to watch this video to see what was the problem.

I took mitsus training and was impressed. They had a couple full vrfs with all the different air handlers and indoor heads all hooked up along with their controllers. Instructors were good too. Goes to show how much can change from one location to another. The joys of a global company. Great video!
What location did you do it at?
@@HVACRSurvival Burnaby in BC
@@HVACRSurvival I did my Citi Multi Training in Dallas, TX with the same setup. I just do the HVAC controls side and integrate into the units, but since I had worked on them in the field so much during install I did quite well in the simulated troubleshooting sessions they had. They are my favorite units overall if the installation is done properly.
Just replace the whole indoor unit. Way less in labor cost. Plus the customer gets a new warranty
I ask them to quote it that way I don't know if they did or didn't. I agree with you
Plus it's nice n shiny, and not a disgusting mess like that. And then what if you get it all back together and that blower motor goes out. Then you get to do it all over again.
@@brnmcc01 while I agree the unit doesn't have to be removed to replace the blower motor. Maybe?
@@natepeterson7145 Replacing the blower motor can definitely be done on the wall. It's still a lot of work though.
Replace. The whole unit is much cheaper.
If anyone says you don’t know what you’re doing, please refer them to your supermarket system videos.
Or refer to the nasa videos where he partners and helps nasa. I’m pretty sure that if you do hvac work for nasa, then you know exactly what your doing.
This guy can fix pretty much anything
Appion, recovery machines don't allow the refrigerant to get into the crank case, so there's no need to purge. The parts are available to completely rebuild them or send them in for a flat rate rebuilding about 1/3 of new. When I have to pay for my equipment I like last fornever.
Also another trick with the appion. 1/2 turn on the blue valve allows the refrigrant to flow backwards through the recovery machine. Can releave pressure on the high side, before you remove connections. I have used this to get the appliance back out of a vacuum if needed without breaking a connection.
Thank you for the information, that will come in handy
Really nice .... thanks for posting the follow-up.
Man i hated residential. Moving to resturaunt refrigeration and hot side was a great move for me. When that guy was asking you if that head was easier annoyed me and i wasn't even there.😂 like dude ill talk to you when I'm all wrapped up.
I just had a call where the customer said to me I want to watch you so I can learn about this. I wanted to say I’m not an educator, if I was I’d be a teacher.
Fantastic video thanks 👍 if bob’s hand was sand paper and his pecker was wooden he would be pissing out a tooth pick
Loving it 😁😁👍👍
I’m with you on residential work, that’s all I do and I want out. I don’t really have any commercial experience and I’m just unsure if 20 years residential will carry over well.
It depends on the commercial work but 90% of it is the same. Just larger equipment. Chillers and other types of equipment can be a learning curve though. Your 20 years should carry over fine. Especially light commercial. I’ve done everything from high rises with chillers to small wine cellars in a home. It’s all the same stuff.
@RandySmith if your good with residential you'll be fine with commercial. It just takes time and it can be like starting over again at times
Ehh I personally prefer residential. It’s easier to work on for the most part and it’s easier to get to. No mile long walks across roof tops and no having to rope up a compressor 30 ft
@@dantemariscal8679 amen. The malls are the worst. Here in Georgia all of the roofs have river rock on them. You have to check in with security, give them your drivers license then illegally drive around the building to get to the roof. It’s a nightmare.
@@AaronPowellvox 🤝🏽that’s exactly what I’m saying and then my biggest nightmare is when none of the units are labeled 😵💫 jeez one time I spent an hour and a half finding the unit I was supposed to be working on. What a headache and I still had 5 other calls that day. Don’t believe what hvac techs on TH-cam say residential is definitely better
Just spent a week in Cleveland at Lincoln’s Tig welding school. Ohio is one pretty state! Cleveland had some of the best sunsets. You sure are lucky, Rick!
Thanks Brian, it's where I'm stuck for now😁
Got to say I don't do much refrigeration and I'm always jealous of all the cool tools you have, but that job looked like a pain in the ass... I have pretty much stopped doing domestic refrigeration as we don't have any hvac here, its just commercial refrigeration that I enjoy but I don't get much of that either....😢
It took longer than I was quoted. That's always great... said no one 🤦🏻
Great video Rick! Best tech on TH-cam hands down. ( my opinion). Lol
You're the best!
Awesome video learn something new everyday with your awesome video
Great job Rick.
I appreciate the work you're doing and content you're providing.
As a fellow tech [huge sarcasm warning] it's a let down man, I'm still waiting for you to teach me how to get the flare nut on the pipe after I make a flawless flare 15ft up on a ladder
🤣👍👍Thanks Man!
Wow thanks for all the detail never done one but I may have to in near future just diagnosed failed stepper motor on a mitsubishi mini split least I have an idea of the rediculous process
Every little bit helps🙏👍👍.
my yellow jacket core tool has also been junk since day 1. would not reccomend.
huh? Rick is one of the best HVACR technician on TH-cam (if not THE best), he knows a lot, experienced and really honest (not trying to scam ppl)
Mitsubishi is a good company in general but those things are just EVIL, not made to be serviced, complicated and not much technical info, apparently not good training too
You're way too kind but I really appreciate your support.
I couldn't find it on the tools links you have in the description, which open ended torque wrench are you using? (14:30 timestamp)
Sorry trutechtools.com/Hilmor1963826DigitalAdjustableTorqueWrench/?AffId=42
Hi Rick
My kids bought me a Hessair unit for my garage. Some installation required Ha!. It had a small leak I could not detect. I figured it had to be the flare. Did the flares again still leaked. I bought flare seals on line. I haven't had a leak sense. Have you ever used them?
Great video.
I’m assuming those are the nylon insert that goes between the flare face?
@@HVACRSurvival yes
I’ve never used them, but it looked interesting
Great video as always. Greets from Germany 🤙
Awesome! Thanks Germany👍👍
Super interesting video (I'm not a tech). We've had a couple of techs out for a no-heat condition on a 12 year old MUZ-GE15NA. Pressure is fine, and they both said it's the reversing valve, however they said it's it not worth it to repair and one of the guys guessed it would be $2k to $3k to fix. The original installer wants $12k (after a heavy discount) to replace it and the inside unit.
We're going to use a room heater for now and I guess start saving up.
I wish they'd build this stuff to be easily serviceable (by a tech, not a lay person). Sorry to rant...
I like hearing from my viewers whoever they are. 👍
i would buy another indoor unit new and 400 dol will do it :D
Curious how old the wall units are. They sure were corroded. Looks like dissimilar metal corrosion.
I'm not 100% sure, but I would guess somewhere between six and seven years old.
Hey mate love the content, what are those arms called?
I think you can see the name in the video. I’ll have to look again. You should be able to find them on a Google search.
Yes could see you returning, as for training keep to the basics, as for us we would have re done flares, left under 3500 kpa nitrogen pressure for a few days, if no loss evacuated to appropriate microns calculated charge, THERE IS NO OTHER WAY TO DO THIS.
I can agree with your comment on a new construction project when there’s no pressing time line or other variables. But if your a service tech working for me and you want leave a customer without air/heat or refrigeration for a few days because you want to pressure test a flare fitting you should be able to get right the first time, every time. You are NOT qualified to work for me and will be FIRED.
Nice job Rick! 😂 the commenter Karen voice was Killin me. I'd be fine if i never saw another ductless regardless of the manufacturer.
😂🤣🤫👍👍
Amazing 👊👏👊 craftsmanship
Thank you 🙏
I got to believe after the labor, way cheaper to throw that unit in the trash and replace it with new!
I guess that depends on what you think we charge🤫
@@HVACRSurvival true but I am a contractor just north of you so I have a pretty good idea. I also know what replacing the head costs too!
Don’t let the keyboard warriors get to you!!!! You do great work.
I appreciate that, thanks for your support! 🤜🤛👍👍
I hate all mini splits, there’s way too many DYI installs out there. I don’t like working in living rooms and elsewhere in residential. I would rather be in the furnace room or on a roof top, even a hot restaurant kitchen first
👍👍👍
Why do the coil? Another couple hundred bucks would of saved 3 hours in labor
🤷♂️ I had him quote it both ways. I think it’s more money than what we thought to go with New and every time I ask, they get pissed off like I don’t trust them.
You already knew that there was a leak, I wonder why it leaked your recharge.
Why wouldn’t I.? Customers willing to pay for it I’m gonna recharge it.
Even if I could do what you did I wouldn’t. I would install new head. Even if it was in warranty I would eat it and get in and out . Way to many possible call backs .
It's not my company so I can't do whatever I want. It was not in warranty and I also do not do the quotes but I did request they gave it as an option to replace the head whether they did or not I have no idea
Its not rocket science, its geothermal science 😂😂😂
I had a Mitsubishi system that had 8 different heads and leaks didn't show up until i hit 500psi.
It was a new construction and left 350psi over night and kept dropping 10 psi over night and couldnt find it with bubbles neither. At the end i i dumped some 410 with 500 psi and found it with leak detector. Left the 500 psi over night and next day no leaky leaky
Got to be smart than what your workin on
Straight up bullshit! I been installing them at work, they will be getting new heads trust me.
What parts bullshit? Do you tell your office what they're going to sell? I have no control over that crap.
Just all the work you have to go through to swap out that evap. And yes I tell them what we are going to be buying. I have put in about 8 so far. I hope they never leak at the evap. @@HVACRSurvival
Not for nuthin mitsu should of sent you a whole new head
Good job Rick, Those negative people are just trolls, they harass you cause they have nothing better to do.
Or have no clue how to do what Rick does. 👍💰
No doubt, not saying I know how to do everything either, but can do it better than a basement troll.
This trade can be extremely toxic full of hvac super hero’s (who you know do worse work than they claim)
I stopped posting hvac content on my instagram channel because of stuff like that. Some guy literally told me I shouldn’t use a swager because they cause micro leaks on the swage joint 🤦🏽
@@dantemariscal8679 it’s constant chest thumping. I have left so many groups because of it. 28 years and apparently I’m terrible and do everything wrong. Lmfao.
Let’s be honest- this si the most difficult, intellectually demanding of all the trades, by far. You need to know physics, electronics, plumbing and even chemistry. Yet there is no serious training licensing like plumbing and electrician. Barriers to entry are thus low and demand for service people are quite high. ? Labor rates and Margins are also quite high ; owners doing quite well, but not passing much along to their service people. And of course. Clients want latest bells and whistles, perfect interior climate conditions , despite their lousy ductwork installed by spec builders, to pay for hi quality work , units more complicated each year, and parts are cheaper. WHAT COULD GO WRONG ? LOL
I've never met a single technician that enjoys working on mini splits. The only people online who defend mini splits to the death are home owners. They could be alot easier to work on if the engineers thought for two minutes on how to make them accessible.
Why can't they have an electrical section that's easy to test in like every other piece of equipment?
That's my whole complaint in a nutshell 👍👍. Thanks brother
Don’t let the jerks on here with nothing better to do get to you. I enjoy your videos. No BS. Real world work and solutions. Keep up the great work. It’s far easier in this world to be a jerk than a humble and friendly person. That’s what keeps me going when dealing with people who think their god’s gift to the rest of us. I just nod and then do my own thing!
I appreciate that, I find it fun to show face when people say stupid stuff then I prove it on video.
@@HVACRSurvivalAbsolutely. I’ve been watching you for years and you’re a wealth of real world out in the field knowledge. Thanks for your willingness to share that knowledge with the rest of us who genuinely appreciate it.
Great video, don't worry about the idiots. I did HVAC for over 50 yrs. and once in a while you run into clowns. As Ron White the comedian said, "You can't fix stupid" and people like that are stupid. Thanks for the video.
You are right I figured they were made that way for intelligent people to learn from . Yes you can learn from STUPID , DISRESPECTFUL HATERS, HOW NIT TO BE STUPID ,BE COURTEOUS AND FRIENDLY
mitsus are highly efficient; and break down alot and cost alot in repairs; currently waiting on ac guy to fix 2nd floor unit AGAIN, its always something different, compressor, several control boards, multiple leaks ( each a different place, mostly indoor units.
the systems are only 4 years old…, parts are covered but not labor or $ freon $$$$
what a bunch of junk
That mini split holder is pretty clutch. Could definitely come in handy for behind-unit connections
Definitely!
Didn't you know Rick.........Bob is the best at being an arm chair QB.....He threw 4 touchdowns for Polk HS from his couch. 😂😂😂😂
Bob must be 200 yrs old according to all his proclaimed experience 😂. Thanks for the video Rick 👍
Can't believe all the work to replace an evaporator coil. I remember when parts lasted a long time.
This is all we do in the Uk, coil changes …. Always indoor leaks. All manufacturers as well , complete joke
It’s funny how many people say they haven’t had any leaks 🤣👍👍
i always hated installing their evap and working on the condenser or electronics JUNK
Good vid Rick ... You should teach as you would be a good instructor ... Thx
I'm a lab style teacher, I didn't like the bookwork when I was helping with the apprentice class.
Mini-splits suck. I know they will only be more prevelant, but it's just plastic junk. I definitely prefer ducted cooling.
One of the best HVAC channels available, I always learn some little detail. Looking forward to "#3 " in this series. :)
🤣 I'm hopefully done for a while at this location.
I only like appion valve core removal tools.
Rick you are the best ! Bob needs to pound sand !
This music layered over the audio is not it man.
Great video! Lots of people drink the haterade, but not a lot of people are super versatile in this trade, you are. Keep up the awesome work and videos!
F Nope. Not desperate enough to work on those things.
Mini split... shudder
For those of us that are hearing impaired the use of background music makes it difficult to understand what you are saying. Thanks for your consideration.
Sorry about that, when there's spots that don't have any talking that's generally where I add that, it helps make the awkward silence go quickly. I'm sure you've used the closed captioning, I'm very surprised how well it picks up what I have to say, especially with the slang terms that I use. I appreciate the feedback and I appreciate you watching! Thank you
Mini splits are the worst to work on especially if you're not familiar with how that particular head unit goes together. All of them are a pain in the ass compared to anything else. I'd much rather be working on a Hoshizaki, or even a PTAC. Fuck the residential engineers in the comments.
Agreed 👍👍
i hate mini splits im curious why in the world would you spend so much time replacing that coil when you could have just replaced the whole head?
Easy. That’s what the customer choose to do. I get paid the same either way.
I just put in 5 Mitsubishi mini splits for the first time they for sure do not come apart like a Daikin which I have done 100’s
I really dislike daikin . Mitsubishi is a good company
Agreed 👍
When was the last time that unit was cleaned those mini splits are mold magnets
🤷♂️
I thought Mitsubishi Heat pumps were supposed to be the best?
Try watching the beginning again about 45 seconds in and you’ll have your answer.
I'm surprised they didn't just send a new indoor unit all together .
Btw for 1/4" tubing i find the can opener on the Leatherman does a decent job at deburring .
Are you getting the new Leatheman Arc Rick ?
I haven't heard of it yet. I currently use the surge, I also really like the wave but it didn't hold up very well, so I have two of those waves for backup
My heat pump vendor in Denmark says the same about Mitsubishi. Good units but no support and training...
Do you know why mini splits are often problematic? There are numerous reasons. When you attempt to fit many devices into a small space, it usually doesn't end well. These systems often consist of small diameter, thin copper lines packed into numerous turns, and a tight chase, which increases the likelihood of kinks and flaring on the small copper pipes, leading to a higher chance of leaks. Moreover, in coastal areas, where exposure to the elements is common, having the electronic board outside is not a good idea.
In addition, the small wires and connectors connected to the board are hard to work with. Their tiny size not only makes troubleshooting difficult but also leads to a shorter overall lifespan. In commercial establishments, mini splits tend to accumulate dirt quickly. Attempting to clean them near the evaporator and blower can be a challenge due to their small drainage passages, which are hard to access, and their sensitive electronics located close by.
I've only scratched the surface of the major flaws in this setup. When it comes to tech support, be prepared to spend an hour or more waiting for a callback during the summer. In contrast, with central AC systems, I can resolve about 95% of issues in just 20 minutes to half an hour because I have the necessary parts and can temporarily rig the system. However, when dealing with mini splits and their delicate electronic boards, it's a different story. If something goes wrong, you're stuck with a malfunctioning AC system in the middle of summer. Mini splits should be treated as disposable units. If they are a few years old, consider replacing them, especially those with multiple evaporators, as the more complicated they are, the more Murphy's Law seems to apply.
I agree 💯
Ive installed 4 seperate systems at my house. I have a total of 6 zones and 4 outdoor units. I have 24 flare connections and I have never flared anything in my life except brake lines. Since then 7 years ago I have had not 1 issue. Not 1 error message, not 1 leak, not 1 failure. These units are running year round. Right now all 4 systems are providing heat @ 22F they are all low ambient systems. I have to say installation is KEY. yes its luck of the draw when it comes to indoor units leaking. but A coils leak too and condensers. But I will say I have may more points for potential failure with so much hardware. thats where this becomes an issue. I installed all the systems myself and had a guy do the startups. So far so good.
how are you?!Hvacr, pro content!be well. 😎
I have never replaced a mini evap. Only the head. I hate minis. All OEM parts, outrageously bad boards that are expensive, and almost no tech support. This past Wednesday, I called Trane to get into the Mitsu tech que. I left my number and still have not gotten a callback. It's Friday evening now. Just junk, plain and simple.
Exactly. Thank you for sharing!
Looked like an all day job to me
It was near it 👍👍
Great 🎉 job 👏
Thank you! 🤜🤛
thak you
Your welcome!
Blower wheel are dirty every few years. No matter what. Don't put them in kitchen area especially.
Definitely don't put them in the kitchen, the grease is horrible, I showed a video where I had to clean that out, total mess
Fun times😂. Frankly with a lot of this stuff it’s all down to the support from supply houses, my local CE (Carrier) has all knew people and took 20min to get a filter.
Also I just had the same thing happen with that “BluVac” core tool. Junk.
Awesome video Rick, you did a good job, you can hate anything you want to.
Hell yeah 😏😂😂👍👍👍
Great video! Nice finesse on those wallmounts. I’ve been to a few Mitsubishi City Multi classes. They have some really good instructors and some really bad ones. I stopped attending a 3 day seminar because of a couple lousy instructors. They ran through the material like robots while tossing a giveaway toy across the room to each other. Whenever a student needed help with the software they’d tell him/her they could figure it out later and just kept rolling. Basically, they ran through three days of material in two days. Everyone was lost half way into the first day and it got progressively worse.
That’s exact thing that happened to me. And I just called him yesterday on a brand new unit and hit the button for them to call me back when an agent was available and I never got a call back. I wish we could stop selling their shit
Great video🙌🏼
It’s More easier and ecnomical to replace whole indoor unit.
Would a 9,000 BTU mini-split be too big for a 9 x 12 room?
I have been using a 5,000 BTU window unit, but now we can't use window units.
If it was my house I would have just replaced the 2 head units then maybe later get the replacement coil then I'd have spare head units.
I’ve replaced an indoor coil on a mini cooling some elevator equipment. I was dirtier than the elevator equipment when I was done. Wish I had just replaced the whole indoor and remade the flares. Hind sight …..
Cant listen to the haters. Thanks for all the useful informstion. Now retired have a great day keep putting out all the work you do. I'm sure the customer lovees thst you solved their promblem. Where others just gas and go. Great Job!
@HVACR Survival the Mitsubishi class I went to a while back said it's ok to use Nylog as long as it's not on the flare face.
I think there will be plenty of opportunity for practice. Mini Splits are generally junk. They are very intrusive to the customer
All mini splits suck😂. Expensive throw away units
Great video Rick, keep up the good work. Can't keep all the trolls happy, but you can keep em fed 😂
Bob probably could not make a pimple on your ass when it comes to this trade, Keep up the great work
I love the appion core tools. Best built in the business. There core depressor tool and charging tee is built just as tough too.
Those Mitsubishis run low superheat - between 0-5 degrees or so to cool the compressor
Rick The Man ✊🏾
Just wanna say you are one of the best techs on youtube
I really appreciate that! I truly feel as though I'm doing the best I can and hoping it helps people that had the same questions I did or do.
DONT READ THE COMMENTS…or if you do, pay no attention
Like so many jobs, about the time you're good, you're done.
Genuinely curious would it not have been easier and cheaper to just replace the indoor heads with new as opposed to repairing them? labor would be less than half. I know with a lot of ductless the new heads aren't compatible with an older condensing unit so not sure if that's what you encountered here.
I'm just a tech, I don't do the quotes, I asked them to quote it both ways.
I would not flaire the connections !
I would cut the flares off both connections and swage and braze the connections as it more reliable than flared connection from expansion and contraction due to them going hot and cold over years the nuts start to loosen and then you loose your refrigerant !!!!!
I agree but that’s not allowed by Mitsubishi.
@@HVACRSurvival but by the time the unit dies it would be out of warranty any way
Plus how would they know as the wall mounted in door doesn't get sent back
Just the part like the fan or the indoor pcb gets sent back not the whole indoor as if that was the case it would be like reinstall of the indoor part
I think they make them like that so they loose refrigerant in the first place so it kill the ac so you re new it
The flares on the in door are there for factory use as in pressure testing at factory with ofn !
I've worked installing ac and refrigeration and big refrigeration I've worked on big packs with all the different makes you can get in refrigeration units and massive blowers in freezers warehouses and that's a challenge as a warehouse freezer full of food is more critical than a Aircon as the food will perish so there's a lot at stake working on industrial refrigeration!
I agree like I said. How would they know? I make TH-cam videos think about it, I’ve done it I just haven’t shown it. Far as the second part. Yeah, I do grocery Refrigeration and industrial work as well, check out my other videos, I hardly ever do this candy ass residential shit anymore. I hate residential. I was all that was available at the time and that’s why I got sent there.
@@HVACRSurvival yeah I prefer working on big refrigeration plant and not on small commercial units and ac just installing it and not repairing the pcb inverter boards and when u speak to Mitsubishi about this subject they don't seem like they know what they are doing when you get a problem with the boards they say oh it could be the compressor or the pcb and thats 2 expensive things that could go wrong ffs 🤬
That's the reason why I don't like fixing ac units to fiddly!!!
Nylog was taboo at the last Mitsubishi training I went to.
I feel your pain.
LOVE the flaring tool - we NEVER had those during my time in HVAC.....Now I will say though is that we DID use to use oil on the flares.....trick from an old timer during my HVAC time....lots of peeps nowadays like using nylog though...both do the job......
I like both at different times
Too finicky for hassle of it !
Good Video Rick. Glad I don’t do resi and have only come across a few mini splits. Not my favorite thing to work on to say the least. Thanks for keeping it real.
Well said!
