I installed a 9,000 btu Mitsubishi Hyper heat during covid as I had to work from a windowless basement office and absolutely love it. So quiet and powerful and did not even think about it as a heat pump until winter we had a deep cold snap and my office was so toasty kids were always in it. Installing a 12k version in the living room this week and want to install a 3 zone for the upstairs bedrooms next year. Have only ever had window units and hate them all. Nothing but praise so far. I did hvac work before moving to Cisco networking so install was very easy. Will se how they are a few years from now as that will be the real test!
There great when they work, trying to decide if a control board or another electronic device is truly bad is the problem. They don't have a cut and dry procedure for things.
@@HVACRSurvival Yes I fully agree. So many modern appliances have excessive amounts of electronics it makes them nearly impossible to repair. I have been looking through the service manual for my Split system and while it has flowcharts and such I am sure an actual failure will not be straight forward. As an example my flare was leaking and a year later the error code it gave made no sense but it was just low on gas.
My advice is single zone. If you just have 3 head units upstairs, get a 2 zone and then get the master bedroom it’s own zone. If something goes wrong, your entire upstairs will have something. They do make 6k btu units too, in the Hyperheat only from what I’ve seen, and they perform!
@@SovereignTroll I did not install this system I'm just the service tech. Far as selling them a power conditioner know I did not do that nor do I carry one on the truck to sell them. I'm still waiting on them to approve the repair.
@@HVACRSurvivalFujitsu seems to be coming up with very nice training. Attended a class and was impressed with the simple diagnosis’ instructions and repair instructions. All on their app. Makes life a lot easier.
Probably feels warmer .. esp if these units started leaking a while ago.. you will lose heating long before you lose cooling in a slow leak minisplit. If you live up north having the heat come out of the ceilings sucks. You get get hot face and icy cold feet.. those wall heads will blow it right in your face.. I put Fujitsu mini in my house.. ducted ones with floor registers .. backed by gas heat. Gas heat comes on below 20F so I can feel nice n toasty.. I hate cold so I keep my house quite warm. Above 20 the heat pumps rock. I worked on a lot of different systems over the years but I can sympathize with them. Although I’d probably still use the heat pump functions on milder days ..
Like he said, "probably blowing cold air". Even 80 degree air blowing on a 98.6F body is going to feel cold in a ~65F room. We have an air handler in an unclimatized attic. You can't adjust the fan runtime, after the compressor shuts off. It's like 5 minutes, fixed. Also, it turs on immediately when the compressor fires. So, that obviously means some cold air, too. It would've been nice for the delay to be on the front end and a more rapid fan shutdown, at the back. I'm not at all down on heat pumps. Just think they need more adjustability, especially for those replacing A/C units in hot/cold attics.
I wonder if the connections were leaking at the back of the indoors and there was a gentle draft from the cutouts blowing the refrigerant through? Most remotes usually send every setting at once, you can cover the IR with your hand and send everything on the last press. Good for setting multiple units or not waking people up with furious beeping
Just did a compressor on one. The back nut you’ve got to do blind. Sooo much fun doing those. Went to the last class on them. Learned a lot on the newer ones. Depends on who’s giving the class. Some are just a waste of time.
Nice video Rick, I spent about 2 months in Findley Ohio working at an Iams Dogfood plant and everyone had a pond in their yard. I asked one of the guys what was up with all the ponds and he said if the homeowner had a pond it decreased their homeowners insurance.
What about the extra danger of a small child drowning? Seems like that would be a much greater risk. Maybe those departments should invest in tankers and drop tanks instead.
We try to avoid installing multi head outdoor units, there are always problems with them. Unless the customers *REALLY* want a single unit outdoors, even after telling them all the problems they're gonna have.
I was curious about the advantages vs downsides of multi indoor/single outdoor. I just had two separate single in/single out units installed at my home and after the fact I thought "why didnt I do one outside unit with multiple inside AND room to expand?".
We’ve been selling Mitsubishi for well over 10 years now and really haven’t had too many problems, mainly leaking flares. Unfortunately the installers are unbelievably rammy and set in their ways (definition of insanity doing the same thing over again expecting a different result) they work incredibly well but man you just can’t get in there to work on them. Im sure you know about my link drive?
I worked in the field for a number of years and most of the time the prior HVAC TECH did a turdly job. Either the flare was bad, the soldering or brazing was poorly done, the use of some cheap weird mix of gases that just do not work correctly or the system was charged to the max when all that was needed was a blower belt. I just do not understand why taking pride in one's work is so hard to find. I feel your pain fella.
Honestly dude, it's pick your poison. Each 1 has just something stupid and ridiculous about it. Not to mention they are ALL less than service friendly. Mitsubishi's in general are the best imo. Most patents in the trade. Carrier/Bryant's I'll say are prob 2nd best. Depending on the generation I guess.
Minisplits always sound like a good deal but every HVAC guy I spoke to hates working on them and hates supporting them. We ended up going with a newer Ruud 4ton standard high efficiency (not the full variable but the 3-stage with some range variable) and it's been fine. It doesn't have fully variable heat either just 2-stage but should be fine longer term compared to these splits.
You cant charge precisely by subcool and superheat, however they can still be indicators of low charge etc. i.e. all EEV's wide open and superheat is high. For a quick charge to get a system up, running all IDUs at full tilt and getting the superheat to correct on all will get in the ballpark for minimum charge. What was left in a system that low could be fractioned R410. So who knows what blend you wind up with without a recover and recharge with all new R410
We quoted new refrigerant when we are going back, I don't know how you could rely on superheat when the electronic expansion valve is going to open and close to maintain whatever superheat is calculated at once. However sub cooling is going to tell you whether you have enough available liquid to even do the work. That's why I went with subcooling. You're not going to find in any of their books what the subcooling should be, like I explained in the video I am just getting it as close as possible and it worked. It'll get recovered and new weight in when we're done.
@@HVACRSurvival I like your reasoning.... I'd do the same. Get the system pressurized enough to do a good leak detection job. Then, when you have the parts/time to properly fix the leak...THAT is the time to do the fancy suck-it-down, weigh-it-in process. I look forward to your video showing the leak fix job, then the fancy stuff... 🙂 Thanks for your great video... BTW, the reason so many flares are an issue is because (IMHO) not enough installers know what a torque wrench is, nor how to use it on the flare joints. (just my opinion of course) ....but I've seen enough sloppyness by installers ...
Splits refrigerant charge is easy to work out, factory charge will be ok to cover a set distance between indoor to outdoor unit, then additional is worked out on liquid line length, X amount of grams per metre , as per manufacturer instructions
Yes always reclaim and start again after leaks found.😢Fractionated gas is bad gas you can Ean up chasing your tail.Domestic units have under 10 kg of ju ju.So do it once and properly
The frequency on these inverter compressors is usually quite high since their motors are not two pole but more. I would say most of them are four pole, so 60Hz would only give you 1800 RPM, 150Hz will be 4500 RPM. Although I have encountered ones with six poles and even eight poles.
I liked this video, it’s annoying how commenters love to criticize and say “oh no recover it and weigh it back in!” But that’s not realistic with many of our time frames. You got ‘em taken care of 👍🏻
I’ll never understand why your title this video like this. Why not just write “I hate to learn how to work on “new” things. I’ve been overseas and splits are far more common. Moved back to USA and every single hvac guy whined and complained about how splits aren’t as good as central systems. Splits may not be better in all cases, but far too many hvac guys don’t want to learn how to do something new. Shitty title for what could have been a decent video. Hard pass
Because it gets views. It's called marketing plus I hate working on the pieces of shit but I've already established that. I'll be going back to this place here next week to replace the evaporator's. In case you were interested
mitsubishi units are junk- ours are 4 years old and have gone thru several compressors, many boards and $$$$ in labor., oddly the #3 outside unit , the small one has been fine.
I don’t like the mini-splits and there not going away and these VRF units are a pain because I just don’t see a lot of these units learn how they work and then you don’t see one for a bit nice video brother
@@HVACRSurvival I would really like to see your process for fixing the leaks, recovering the charge, pumping it down, and then weighing in the new charge.... which port do you use. On the unit you are working with it appears there is a charge port between the accumulator and the compressor.... did you use that for your gauges?
This is exactly why I do not install one system on larger or two story homes. Because it’s always an emergency when the ONLY one goes out. also, never install mini splits if you can put a central system in. Also, I never work on anyone else’s but my own mini splits. Too many jackleg DIY’ers out there.
@@kevinmills5293 Exactly. I was forced to become a "jackleg." Couldn't get a call back from "reputable" companies despite wanting multiple units installed - I am not calling after a third request for a quote. I did hear back from the white truck meth heads wanting me to fund their new bass boat. Bought my own tools. F'em all. This shit ain't rocket science and I suspect I have more attention to detail than most.
Yeah, until the AC company quotes you $15-18K for a furnace/ac upgrade when the equipment cost is sub $5K... I had something in my a$$ when I had a colonoscopy but no damn glorified plumber is gonna do that. Companies that charge like that should be wearing a mask and carrying a gun...
Mine is brand new, it doesn’t sound like that at all! Mine doesn’t make any noise whatsoever. The little condensate pumps are the noisiest parts, and those just sound like an irritating kid trying to suck up the last bit of soda from a straw. My outdoor unit is (virtually) silent..no ductwork, so efficiency is fantastic. I’m still trying to figure out if I should let it run continuously on auto or reprogram it to stop when temp is reached. I’d encourage you to live these newer units, because I’m so blown away by mine..
This was a medium price range unit (I believe), when you get into the P series, they are higher quality. Also, anything in the hyper-heat model range is really efficient. Also don't forget I had the cover off so you're gonna hear more noise from the compressor specially, when it's running at the high rpm, it was running.
MINE IS 15 YEARS OLD (MR.SLIM) AND QUIET AS A MOUSE. KEEP THE FILTERS AND OUTDOOR COIL CLEAN AND HAVE NEVER HAD AN ISSUE. NOW MY TWO YORK SPLIT SYSTEMS THAT WENT IN AT THE SAME TIME WERE ABSOLUTE DISASTERS. GRRRRR.........
We had a Mitsubishi MiniSplit that lasted our family 18 years. Ran it summer and winter, no issues. No training for install, was a total DIY job. We only replaced it when it became impossible to repair. As someone else commented, Mini's were marketed for DIY'ers and we loved ours. Our neighbor, a refrigerant repairman who worked on commercial systems hated the Mini Splits too, was never really sure why.
Cody D no not arrogant at all, I'm pretty good at working on them and stay up to date on them as well, I don't hate working on them and I know they're fantastic. It's people like you and your buddies that just make me and other real techs look that much better so not sure how that's arrogant. Oh well
@hvac01453 well, they have to be as complex as they are to do what they do so efficiently. When they first came around back in the day, they were alot more simple designs, but also half the seer ratings and cop's and couldn't operate anywhere near the low ambient temps they achieve today in heat mode. Ya the multiple circuit boards can get complicated if you're having board issues. Mitsubishi has some basic to advanced courses you can attend that will allow you to become more proficient with them. I highly suggest them to anyone who hates working on them. I used to be one of those techs as well who hated working on them. Because I didn't know enough about them. I get it. But the knowledge is out there available to who wants it.
What about their free tech support site. Mylink I think it's called. The class I went too they just showed us where to find the service info on the site. The trainer also said its ok to put nylog on the backside of the flare to keep the nut from skipping. I'm sure you know that already but in case you didn't. Good video!
@Jay to verify your question. If you were listening in the beginning of the video I told you exactly about Mitsubishi's shitty training program so that would probably be the case wouldn't it? But I was able to get the shit running huh? Not bad for an idiot that doesn't know what he's doing huh? FYI it's still running and I'm scheduled to go back to install the new evaporator coils.
Just a regular customer, why do you hate Mitsubishi, because the training was bad or since their quality is poor? On the latter matter you can not convince me since I have a mini split that it's about 40 years old that puts a smile on my ac service guy 😅
17 year field service tech here. You are wrong, my man. Mitsubishi makes the highest quality mini-splits out there. That’s not to say they don’t have their share of failures, but when it comes to overall reliability and SERVICEABILITY, there is no better manufacturer out there.
As a service technician, we usually listen and you did not listen. I never said the equipment was shit. I said the training sucked ass. I called out the Kentucky branch because they needed their asses handed to them for doing such a shit job. 68,000+ people watch that video so if that don’t embarrass their asses for their piss poor training then I don’t know what will.
Hello Rick, I'm need some Schrader valves on my r-22 ac, would they be 1/4", I have a core tool, using brass cap now but sniffer shows leaky on low side. Going to order usa bestec ones just making sure 1/4" 20 yr old heil ICP HP, Thank you.
4 pole motor on the unit, so divide the measured hertz by 2 , to find the rotational speed of compressor.. The service manual will tell you the number of poles the compressor.motor has, usually 4... There a pretty sound piece of kit, like all ac units the last few years, coils.leak on most of them, thinner copper in coils etc etc....
Great video man. Love Mitsubishi myself as our hyperheat three head is our only heat source all winter in New Hampshire. They seem to last forever up here. I have however seen two Daiken systems leaking and failed under 3 years each this year!
Mini splits are nothing more than a glorified window unit many of them are made by communist nations. The manufacturers have a life expectancy of three years on this product parts availability are terrible. They do not provide sequence of operation and clear information regarding their programming. They are going to ruin the HVAC industry as a whole, in the future we’re going to have a very difficult time trying to recruit anyone to work on these things due to limited access, limited knowledge and limited repair parts so if you’re a homeowner thinking about buying a mini split view, might as well just go by three or four window units from Walmart not quite as efficient basically the same thing.
I’ve taken the Mitsubishi training with my company to keep our contractor rating. It’s a waste of time. Literally teach how to read the model numbers and that’s it. Carrier ductless training was tons better.
The title is definitely why i watched lol. I currently have a pending half finished commercial Mitsubishi install that i have no idea how I'm gonna finish. Apparently the Miami Beach code inspectors want a interlocked motorized fresh air damper to be installed with the system....fml. Ive never had a single second of any mini split training so i have no idea how to make the mini split (with all its weird modulating DC voltage) work with the available 24 volt AC (alternating current) motorized dampers. In short I'm not currently a fan either lol
@@mrfrenzy. that's a very interesting idea. I've seen them being used on Copeland compressors for overcurrent protection (normally closed contacts that open on overcurrent). Is there a normally open version that closes when it senses a particular current draw? Or maybe there's an adjustable version where you can set the exact amperage when you want it to close the contacts? Ill definitely look into it though. Thank you for the idea.
One last thought someone thinking about buying these at 157 frequency the compressor rotor RPM is above 9000 do you want to buy something that runs 9000 RPM
Can’t speak to working on them, but owning one so far is freaking amazing. I went from a swamp cooler to Star Trek technology. I had a Diamond dealer install, my ceilings were all open, so it made it easier. Slightly different temps in each room is awesome, so, so quiet..
If you are impressed with those, you'd feel like you were in heaven with a real heat pump system. I can't even tell if it's 80 or 10 outside without sticking my head out the door. You aren't going to like them when you wait a month or two for a part. Those things are very brand specific parts. Central home systems are 90 percent universal fitting parts. I can fix 98 percent of the service calls during the first trip on regular systems. I fix about 10 percent of the mini splits on the first trip.
@@Bryan-Hensley I don’t understand..it is a “real” heat pump. I happen to already have a Trane XV95, but the ductwork wasn’t right for AC, (swamp cooler was great for two decades, until a surge or short caused an attic fire) so I opted for the Mitsubishi as primary cooling, and backup heat
i did a mrcool DIY and it heated and cooled like a beast for over a year still on trailer its on but since moved and wish i could take it with me but i plan on getting another one for sure.
@@shiroken0 the way it shows to route the evap lines is out the back and through the wall, so I was wondering if it gives you the option to route the lines out the sides, left or right side? I hear some of these mini splits do.
Mitsubishi vs Mitsubishi Electric quality. I have a M/E single unit that's still going strong after about 18-19 years, but yeah well beyond it's expected life really.
Things that went wrong with it... well very little. I had a look inside, cleaned the radiator fins etc. The capacitor appears a bit swollen so I have a replacement cap ready. It's lost zero oil in operation. Powdercoating got pretty rusty so I dissassembled and fixed some of that, but it's near the sea, so corrosion happens faster.
I have a zuba central.. hate it.. supply temp always low, aux kicks in all winter.. compressor rarely revs over 10 amps... Ime almost 20 years into the hvac trade.. no clue.. no one knows them and tech support is unavailable.. nightmare
I've put a couple in, never worked on had to work on any yet?🤔 I happen to like RE michel mini split training.🍺🍺🍺🥃🥃 I wouldn't pull it all out to put it back either especially without replacing the leakers, wow 🤔
About 10 years ago was deathly afraid of charging these bastards. But in a pinch get them lines cold get a good deltaT and your good lol. Have a hospital with a file room they are persistent on not leak checking once a year I charge her up. They install them once they had a leak fixed it had to change oil on vacuum pump 4 times to get to 500. Anyhow you can get by.
Very disappointed with ours biggest mistake ever buying 4 huge split units heating cooling, keeps creating problems and do not function correctly all times compared to Panasonic units bought same time, i hated the fact that we had to call electrician to change the board of the sensors that received the signal from the remote control units, happened to different units 3 times, i have no idea why, i thought they would better than any coming from an old company that made heavy industries such as cars and trucks etc
To @ LZummer: The fact that his video has saved so many of us literally thousands of dollars is the exact reason why he SHOULD be posting and why its a good thing that your opinion is not in line with reality.
I just found your channel after a 10 hour day of cursing a Mitsubishi VRF til I was blue in the face. Couldn't agree more. Terrible manuals, lackluster training, and finicky controls.
You know what's funny is.. I just had somebody leave a comment about how much I complained😲😲😲 I get a kick out of those sort of comments because it's like everyone here bitches about something give me a break. I just happen to have a outlet to show the world what kind of bull shit we deal with.
I love Mitsubishi as a customer, ducted with one ceiling cassette in my home gym, five zones, works great City Multi unit outside. Installed and serviced by a Mitsubishi Diamond company.
I’m looking to get a couple of mini splits and I do have a little sulfur water. How does the sulfur water effect these units? 3:26 Does water run through some units or is it more from the sulfur being released into the atmosphere from running the tap?
The gas enters the home from being drawn from the faucet. It travels in the air. If you do some searching for Sulphur water, they’ll give you the truth scientific name I forget what it is, but it’ll explain why this gas tends to attack, copper and other models.
Bet the other guy you talked to about the class was Ralph Wolff, he’s awesome teacher. We love Mitsubishi. That’s almost all I work on. We have awesome support, good training and good recourses
I don't like working on "them because I don't work on many of them." Really? That must be a testament to their reliability. Seems like it's time for a new profession.
Rick, I hate to be a bother about this, and I hope that it isn't somewhere I could have found. But where did you get that rope setup you have? Different than mine, but I am intrigued. Certainly makes light work of roof work. Thank you in advance
Correct, I work on too many different things but my real complaint is the shit school they have and I wanted to call them out. I'm sure they have seen it by now. Hopefully it will cause them to address the issue. At the least it will have other techs looking for the same thing problems I dealt with.
@@HVACRSurvival Yeah fair enough man. I actually rate Mitsubishi very highly, and their tech support here is great. They're a market leader here along with daikin. We don't have gas central heating etc like you guys do, so it's all heat pumps big and small.
@HVACR Survival probably can't answer this but is it legal that your company doesn't pay for callbacks? Or is it legal due to signing a contract? Just curious because I've heard you say that in some of your other videos.
I hate multizone Mini Splits. Formicary Corrosion kills those evaporators. We fail all the time with the flares. The flares behind the heads bite us in the ass.
Correct it gets the air conditioning going again. It's not like it's going to leak out tomorrow, it did what I needed to do to get them by who knows how long it's going to take to get the coil and when we can get back. I actually try to take care of my customers unlike some of these scumbag sons of guns trying to sell them new shit 24/7 cuz they don't know how to fix anything
I found a brand new Mitsubishi American Standard 2 ton outdoor mini split. It’s the outdoor unit only. I’m looking for an indoor unit and wondering do I have to use the same model or can I use a different model for the air handler. My model is NAXS or NV series. I can only find models that are MSY or Trane NTXS. Do I have options or do I have to get the correlating air handler model??? Great video by the way
If they are using baseboard for heat instead of the mini split, they bought a unit from someone that sold them the wrong crap. Our mini split had no issues heating when the temp outside was at 3F.
You must not be a service tech and likely not an elderly person. I heard the same complaint from customers that purchased an high efficiency gas furnace when they first came out. Simply said, people don’t like change and if you’re on blood thinners everything feels colder. You’re also assuming that the customer picked the top options that they could’ve picked, that was not a hyper heat system so I would say you’re assumption is missing the necessary information to make factual based opinion.
i wonder if you are in a house with the shoddy drywall? the shoddy drywall would give off vapors that would degrade metals and would ruin air conditioners.
They are made in China just like most crap, but they are the best of the mini splits, I just don't like mini splits. Everything is proprietary... and unless you know their particular sequence of operation you're going to be lost until you figure it out.
My main problem is taking apart head units on any mini split. Huge pain in the ass and you always feel like you're gonna break something
Basically overpriced Throw away units it’s sad and working on them sucks
Agreed, I damn plastic is so brittle especially if it’s been right by a window all it’s life.
100%
I used clean the air conditioners at my old job i was a maintenance worker at

@AustinMichael what don't we understand? I am 71 and love my mini splits and when they wear out I will buy more.

SHES A LEAKER MA'MA
The guy that's famous for saying that phrase is a complete idiot.
Ole gundy ain't gonna fix er..
I yell this everytime I see a low system
I believe you can use the EOS (Emergency Operation) switch on the evaporators to run in '100%' mode. One press for cooling, 2 for heating.
I think you're correct, it's been so long since I've done it I don't remember. I don't work on these very often anymore. And I'm okay with that 😁
I wonder if the connections were leaking at the back of the indoors and there was a gentle draft from the cutouts blowing the refrigerant through?

Country folk don't spend crazy money like city folk do. $200-$350 can get you a real nice place here. It use to be lower until recently

That's farm ground and he doesn't own that. If you like the food you eat I think you wouldn't want them to plant trees.
@@HVACRSurvival @hillppari get his food from the store.
I'll take a bad part over a leak anyday. Espically on a mini- split.
how old was this system? they havent been selling these indoor units for at least 10 years in europe.
Nice video Rick, I spent about 2 months in Findley Ohio working at an Iams Dogfood plant and everyone had a pond in their yard. I asked one of the guys what was up with all the ponds and he said if the homeowner had a pond it decreased their homeowners insurance.
Sounds correct, were all volunteer fire departments around here unless you're in town with city water.
yeah, because fire trucks can pump from them. problem is many people also have fireplaces and wood burners, which jacks the rates back high. lol
What about the extra danger of a small child drowning? Seems like that would be a much greater risk. Maybe those departments should invest in tankers and drop tanks instead.
Unless some kids drowns in it, you could get sued for open water.... no fence...
I have 3 Mitsubishi h2i units been using for both heat and cooling. Highest heating bill was 110.00 month of January. These are great for heat !
Where, in Florida?
We try to avoid installing multi head outdoor units, there are always problems with them. Unless the customers *REALLY* want a single unit outdoors, even after telling them all the problems they're gonna have.
Let alone that 2 single split are cheaper than a dual split !
I was curious about the advantages vs downsides of multi indoor/single outdoor. I just had two separate single in/single out units installed at my home and after the fact I thought "why didnt I do one outside unit with multiple inside AND room to expand?".
Why is that? Thinking about installing a four zone Mitsubishi unit at my house.
We’ve been selling Mitsubishi for well over 10 years now and really haven’t had too many problems, mainly leaking flares. Unfortunately the installers are unbelievably rammy and set in their ways (definition of insanity doing the same thing over again expecting a different result) they work incredibly well but man you just can’t get in there to work on them. Im sure you know about my link drive?
Yeah, I'm a hands on person that doesn't learn from a manual.
Mylinkdrive is a must have for any service guy, installer, salesman, designer etc. All the documentation in one place
I worked in the field for a number of years and most of the time the prior HVAC TECH did a turdly job. Either the flare was bad, the soldering or brazing was poorly done, the use of some cheap weird mix of gases that just do not work correctly or the system was charged to the max when all that was needed was a blower belt. I just do not understand why taking pride in one's work is so hard to find. I feel your pain fella.
Thanks for sharing👍👍. I agree, it shouldn't be thought of as harder to do a job correct. 🤷
@@HVACRSurvival Thank you for your honesty and integrity on the JOB !!!
@@victoryfirst2878what honesty and integrity? His company installed an HVAC system that leaks
Honestly dude, it's pick your poison. Each 1 has just something stupid and ridiculous about it. Not to mention they are ALL less than service friendly.
Mitsubishi's in general are the best imo. Most patents in the trade. Carrier/Bryant's I'll say are prob 2nd best. Depending on the generation I guess.
You’re right ✌️👍👍
Minisplits always sound like a good deal but every HVAC guy I spoke to hates working on them and hates supporting them. We ended up going with a newer Ruud 4ton standard high efficiency (not the full variable but the 3-stage with some range variable) and it's been fine. It doesn't have fully variable heat either just 2-stage but should be fine longer term compared to these splits.
You cant charge precisely by subcool and superheat, however they can still be indicators of low charge etc. i.e. all EEV's wide open and superheat is high.
For a quick charge to get a system up, running all IDUs at full tilt and getting the superheat to correct on all will get in the ballpark for minimum charge.
What was left in a system that low could be fractioned R410. So who knows what blend you wind up with without a recover and recharge with all new R410
We quoted new refrigerant when we are going back, I don't know how you could rely on superheat when the electronic expansion valve is going to open and close to maintain whatever superheat is calculated at once. However sub cooling is going to tell you whether you have enough available liquid to even do the work. That's why I went with subcooling. You're not going to find in any of their books what the subcooling should be, like I explained in the video I am just getting it as close as possible and it worked. It'll get recovered and new weight in when we're done.
@@HVACRSurvival I like your reasoning.... I'd do the same. Get the system pressurized enough to do a good leak detection job. Then, when you have the parts/time to properly fix the leak...THAT is the time to do the fancy suck-it-down, weigh-it-in process. I look forward to your video showing the leak fix job, then the fancy stuff... 🙂
Thanks for your great video... BTW, the reason so many flares are an issue is because (IMHO) not enough installers know what a torque wrench is, nor how to use it on the flare joints.
(just my opinion of course) ....but I've seen enough sloppyness by installers ...
Splits refrigerant charge is easy to work out, factory charge will be ok to cover a set distance between indoor to outdoor unit, then additional is worked out on liquid line length, X amount of grams per metre , as per manufacturer instructions
Yes always reclaim and start again after leaks found.😢Fractionated gas is bad gas you can Ean up chasing your tail.Domestic units have under 10 kg of ju ju.So do it once and properly
The frequency on these inverter compressors is usually quite high since their motors are not two pole but more.
I would say most of them are four pole, so 60Hz would only give you 1800 RPM, 150Hz will be 4500 RPM.
Although I have encountered ones with six poles and even eight poles.
Carrier inverters can hit 7500rpm
I liked this video, it’s annoying how commenters love to criticize and say “oh no recover it and weigh it back in!” But that’s not realistic with many of our time frames. You got ‘em taken care of 👍🏻
Everyone has a butthole and an opinion 😆✌️✌️
The guy said baseboard costs about the same as the HP. He is smoking something.
🤷 not my money
@@HVACRSurvivalyeah not your job. Give it up, you suck.
I did the diamond dealer class in Kentucky 15 years ago did not learn munch I got OJT and I charge with the same method you do fantastic video 👍👍👍👀🇺🇸
I hope others leave comments saying the same thing about the poor training. Maybe they will change things.
I’ll never understand why your title this video like this. Why not just write “I hate to learn how to work on “new” things. I’ve been overseas and splits are far more common. Moved back to USA and every single hvac guy whined and complained about how splits aren’t as good as central systems.
Splits may not be better in all cases, but far too many hvac guys don’t want to learn how to do something new.
Shitty title for what could have been a decent video. Hard pass
Because it gets views. It's called marketing plus I hate working on the pieces of shit but I've already established that. I'll be going back to this place here next week to replace the evaporator's. In case you were interested
How about isolating the leaking indoor so you don’t send more Freon into space,till you get back.We are very comsciences in Oz land
mitsubishi units are junk- ours are 4 years old and have gone thru several compressors, many boards and $$$$ in labor., oddly the #3 outside unit , the small one has been fine.
Not surprising, sorry to hear that!
I don’t like the mini-splits and there not going away and these VRF units are a pain because I just don’t see a lot of these units learn how they work and then you don’t see one for a bit nice video brother
Very true, their energy efficient BUT with the cost when they fails...offset that savings in my mind.
Speaking the truth brother
Ive worked for 15 years on this equipment, 99.5 % problems human error.
I like your method of practical charging. Once you fix all the leaks, then it would make sense to pump it down and weigh in a new charge.
That's what I plan on doing 👍👍
@@HVACRSurvivalcan you fix the leaks or do you need to replace the head unit?
@@HVACRSurvival I would really like to see your process for fixing the leaks, recovering the charge, pumping it down, and then weighing in the new charge.... which port do you use. On the unit you are working with it appears there is a charge port between the accumulator and the compressor.... did you use that for your gauges?
I thought Mitsubishi was top of the line. What brands do you like for durability?
Rare that they leak. It’s cheaper quality of everything.
@edor Mitsubishi is the better of the group but the training and tech support sucks.
Fujitsu for me. Ameristar from RE is just another cheap GREE.
Panasonic is good.
They are, but they still break down. They update their equipment hardware a lot and makes repairs on them nearly impossible after a few years,
This is exactly why I do not install one system on larger or two story homes. Because it’s always an emergency when the ONLY one goes out. also, never install mini splits if you can put a central system in. Also, I never work on anyone else’s but my own mini splits. Too many jackleg DIY’ers out there.
It’s not just the DIY’ers.
Exactly, all my calls have been installed by a company.
@@kevinmills5293 Exactly. I was forced to become a "jackleg." Couldn't get a call back from "reputable" companies despite wanting multiple units installed - I am not calling after a third request for a quote. I did hear back from the white truck meth heads wanting me to fund their new bass boat. Bought my own tools. F'em all. This shit ain't rocket science and I suspect I have more attention to detail than most.
Yeah, until the AC company quotes you $15-18K for a furnace/ac upgrade when the equipment cost is sub $5K... I had something in my a$$ when I had a colonoscopy but no damn glorified plumber is gonna do that. Companies that charge like that should be wearing a mask and carrying a gun...
If you're buying basic stuff you might be lucky if it's five grand.
Mine is brand new, it doesn’t sound like that at all! Mine doesn’t make any noise whatsoever. The little condensate pumps are the noisiest parts, and those just sound like an irritating kid trying to suck up the last bit of soda from a straw. My outdoor unit is (virtually) silent..no ductwork, so efficiency is fantastic. I’m still trying to figure out if I should let it run continuously on auto or reprogram it to stop when temp is reached. I’d encourage you to live these newer units, because I’m so blown away by mine..
This was a medium price range unit (I believe), when you get into the P series, they are higher quality. Also, anything in the hyper-heat model range is really efficient. Also don't forget I had the cover off so you're gonna hear more noise from the compressor specially, when it's running at the high rpm, it was running.
MINE IS 15 YEARS OLD (MR.SLIM) AND QUIET AS A MOUSE. KEEP THE FILTERS AND OUTDOOR COIL CLEAN AND HAVE NEVER HAD AN ISSUE. NOW MY TWO YORK SPLIT SYSTEMS THAT WENT IN AT THE SAME TIME WERE ABSOLUTE DISASTERS. GRRRRR.........
I had to watch. Two things I don't like: residential and mini-splits. LOL!
I'm with you, I cut out my complaining. People tend to get pissed.
Too many people are brainwashed into thinking they need a more expensive ducted central hvac system.
We had a Mitsubishi MiniSplit that lasted our family 18 years. Ran it summer and winter, no issues. No training for install, was a total DIY job. We only replaced it when it became impossible to repair. As someone else commented, Mini's were marketed for DIY'ers and we loved ours. Our neighbor, a refrigerant repairman who worked on commercial systems hated the Mini Splits too, was never really sure why.
Because he didn't know how to work on them
@@HVACRTECH-83 not true at all, I’m in the trade and most guys I talk to hate working on them. Stupid arrogant comment
Cody D no not arrogant at all, I'm pretty good at working on them and stay up to date on them as well, I don't hate working on them and I know they're fantastic. It's people like you and your buddies that just make me and other real techs look that much better so not sure how that's arrogant. Oh well
@@HVACRTECH-83that may be true BUT, they purposefully made a simple thing so complex, and everyone of them operate differently from the next.
@hvac01453 well, they have to be as complex as they are to do what they do so efficiently. When they first came around back in the day, they were alot more simple designs, but also half the seer ratings and cop's and couldn't operate anywhere near the low ambient temps they achieve today in heat mode. Ya the multiple circuit boards can get complicated if you're having board issues. Mitsubishi has some basic to advanced courses you can attend that will allow you to become more proficient with them. I highly suggest them to anyone who hates working on them. I used to be one of those techs as well who hated working on them. Because I didn't know enough about them. I get it. But the knowledge is out there available to who wants it.
Res boys got it made 😂
What about their free tech support site. Mylink I think it's called. The class I went too they just showed us where to find the service info on the site. The trainer also said its ok to put nylog on the backside of the flare to keep the nut from skipping. I'm sure you know that already but in case you didn't. Good video!
I have yet to ever talk to a service tech that liked mini splits.
I hate all minisplits 😂 nice job Rick
Why?
@Robert M just hard to work on. Everything in tight space and flares are never leak free.
Probably because you don’t know what you’re doing that would be the easiest answer
@Jay to verify your question. If you were listening in the beginning of the video I told you exactly about Mitsubishi's shitty training program so that would probably be the case wouldn't it? But I was able to get the shit running huh? Not bad for an idiot that doesn't know what he's doing huh? FYI it's still running and I'm scheduled to go back to install the new evaporator coils.
you should really let us know how you feel about Mitsubishi and mini-splits.. 🤣🤪🥳
I'm not sure I can. 😲
Just a regular customer, why do you hate Mitsubishi, because the training was bad or since their quality is poor? On the latter matter you can not convince me since I have a mini split that it's about 40 years old that puts a smile on my ac service guy 😅
The training in Kentucky was very very poor. We sell a lot of these and only have a few with these problems.
This is such a great channel. Bringing back all the memories and I loved this work but sooo happy I left the industry for I.T. lol.
😂👍👍
17 year field service tech here. You are wrong, my man. Mitsubishi makes the highest quality mini-splits out there. That’s not to say they don’t have their share of failures, but when it comes to overall reliability and SERVICEABILITY, there is no better manufacturer out there.
As a service technician, we usually listen and you did not listen. I never said the equipment was shit. I said the training sucked ass. I called out the Kentucky branch because they needed their asses handed to them for doing such a shit job. 68,000+ people watch that video so if that don’t embarrass their asses for their piss poor training then I don’t know what will.
Great video, and all mini splits suck. Not a fan of working on any of them
Hello Rick, I'm need some Schrader valves on my r-22 ac, would they be 1/4", I have a core tool, using brass cap now but sniffer shows leaky on low side. Going to order usa bestec ones just making sure 1/4" 20 yr old heil ICP HP, Thank you.
4 pole motor on the unit, so divide the measured hertz by 2 , to find the rotational speed of compressor..
The service manual will tell you the number of poles the compressor.motor has, usually 4...
There a pretty sound piece of kit, like all ac units the last few years, coils.leak on most of them, thinner copper in coils etc etc....
Great video man. Love Mitsubishi myself as our hyperheat three head is our only heat source all winter in New Hampshire. They seem to last forever up here. I have however seen two Daiken systems leaking and failed under 3 years each this year!
Thanks for the info! I finally returned there last week to replace those coils.
Mini splits are nothing more than a glorified window unit many of them are made by communist nations. The manufacturers have a life expectancy of three years on this product parts availability are terrible. They do not provide sequence of operation and clear information regarding their programming. They are going to ruin the HVAC industry as a whole, in the future we’re going to have a very difficult time trying to recruit anyone to work on these things due to limited access, limited knowledge and limited repair parts so if you’re a homeowner thinking about buying a mini split view, might as well just go by three or four window units from Walmart not quite as efficient basically the same thing.
Nobody torque anything on the heads
Probably not
God dealing with home owners is annoying I’m glad I moved to commercial I couldn’t deal with this guys questions…..
I’ve taken the Mitsubishi training with my company to keep our contractor rating. It’s a waste of time. Literally teach how to read the model numbers and that’s it. Carrier ductless training was tons better.
Thank you! I'm glad others are coming forward. It was the same for me
The title is definitely why i watched lol.
I currently have a pending half finished commercial Mitsubishi install that i have no idea how I'm gonna finish.
Apparently the Miami Beach code inspectors want a interlocked motorized fresh air damper to be installed with the system....fml.
Ive never had a single second of any mini split training so i have no idea how to make the mini split (with all its weird modulating DC voltage) work with the available 24 volt AC (alternating current) motorized dampers.
In short I'm not currently a fan either lol
You could use a current relay to detect when the unit is running and control your dampers with that.
@@mrfrenzy. that's a very interesting idea.
I've seen them being used on Copeland compressors for overcurrent protection (normally closed contacts that open on overcurrent).
Is there a normally open version that closes when it senses a particular current draw? Or maybe there's an adjustable version where you can set the exact amperage when you want it to close the contacts?
Ill definitely look into it though. Thank you for the idea.
One last thought someone thinking about buying these at 157 frequency the compressor rotor RPM is above 9000 do you want to buy something that runs 9000 RPM
Can’t speak to working on them, but owning one so far is freaking amazing. I went from a swamp cooler to Star Trek technology. I had a Diamond dealer install, my ceilings were all open, so it made it easier. Slightly different temps in each room is awesome, so, so quiet..
Well they are extremely expensive when they break, parts are not usually in stock. They are a expensive window unit.
They are great when they work. When they break or have issues is when we (the techs) and homeowners start getting angry.
If you are impressed with those, you'd feel like you were in heaven with a real heat pump system. I can't even tell if it's 80 or 10 outside without sticking my head out the door. You aren't going to like them when you wait a month or two for a part. Those things are very brand specific parts. Central home systems are 90 percent universal fitting parts. I can fix 98 percent of the service calls during the first trip on regular systems. I fix about 10 percent of the mini splits on the first trip.
@@Bryan-Hensley I don’t understand..it is a “real” heat pump. I happen to already have a Trane XV95, but the ductwork wasn’t right for AC, (swamp cooler was great for two decades, until a surge or short caused an attic fire) so I opted for the Mitsubishi as primary cooling, and backup heat
@@johncspine2787 I thought it was your only heat.
i did a mrcool DIY and it heated and cooled like a beast for over a year still on trailer its on but since moved and wish i could take it with me but i plan on getting another one for sure.
Do they give you the option out of the evaporator/ blower side?
@@Michael-qy1jz sorry dont quite understand?
@@shiroken0 the way it shows to route the evap lines is out the back and through the wall, so I was wondering if it gives you the option to route the lines out the sides, left or right side? I hear some of these mini splits do.
@@Michael-qy1jz yes you can normally route out the right side of unit all you got to do is cut the notch out.
@@shiroken0 thanks!
Not near as bad as Pioneer!
I think they’re about the same. Pioneer looks like a clone.
I think that this man could be a body/voice double for coach Bill Belichick, he's also a sold HVAC tech.

What detector is that?
Inficon Dtek Status. All tools can be found in the description of the video. I’ve done reviews of it and the Dtek 3.
Mitshubishi never been a service series. I've worked for years at their TV division. Junk.
Another amazing video Rick !
"Its not good". Author sucks... The best what you can do is... to hate such workers.
Mitsubishi vs Mitsubishi Electric quality. I have a M/E single unit that's still going strong after about 18-19 years, but yeah well beyond it's expected life really.
Things that went wrong with it... well very little. I had a look inside, cleaned the radiator fins etc. The capacitor appears a bit swollen so I have a replacement cap ready. It's lost zero oil in operation. Powdercoating got pretty rusty so I dissassembled and fixed some of that, but it's near the sea, so corrosion happens faster.
I have a zuba central.. hate it.. supply temp always low, aux kicks in all winter.. compressor rarely revs over 10 amps... Ime almost 20 years into the hvac trade.. no clue.. no one knows them and tech support is unavailable.. nightmare
I’ve never heard of them.
I've put a couple in, never worked on had to work on any yet?🤔
I happen to like RE michel mini split training.🍺🍺🍺🥃🥃
I wouldn't pull it all out to put it back either especially without replacing the leakers, wow 🤔
About 10 years ago was deathly afraid of charging these bastards. But in a pinch get them lines cold get a good deltaT and your good lol. Have a hospital with a file room they are persistent on not leak checking once a year I charge her up. They install them once they had a leak fixed it had to change oil on vacuum pump 4 times to get to 500. Anyhow you can get by.
I worked with hi vacuum systems. Flare fittings not good. VCR type fittings would work to prevent leaks. Or solder the connection.
There is no "T" in "across".
Never seen a technician complain so much about doing repair work😂lol
I think it had something more to do with the equipment I was forced to work on. And judging from the several other comments I'm not alone.
When you don't know what you are doing...
@@grigorshukerski4689 yep, I'm a total hack 🤫. I'm lucky I knew how to hook up my gauges.
They tell the morons to install them 6" or more off the ceiling. Its like one of those things that is considered to be a major no no install wise
I love Mitsubishi. Unfortunate that ones a leaker. Sell them a new ine
Very disappointed with ours biggest mistake ever buying 4 huge split units heating cooling, keeps creating problems and do not function correctly all times compared to Panasonic units bought same time, i hated the fact that we had to call electrician to change the board of the sensors that received the signal from the remote control units, happened to different units 3 times, i have no idea why, i thought they would better than any coming from an old company that made heavy industries such as cars and trucks etc
Thanks for sharing your experience 👍👍
To @ LZummer: The fact that his video has saved so many of us literally thousands of dollars is the exact reason why he SHOULD be posting and why its a good thing that your opinion is not in line with reality.

I just found your channel after a 10 hour day of cursing a Mitsubishi VRF til I was blue in the face.
Couldn't agree more. Terrible manuals, lackluster training, and finicky controls.
You know what's funny is.. I just had somebody leave a comment about how much I complained😲😲😲 I get a kick out of those sort of comments because it's like everyone here bitches about something give me a break. I just happen to have a outlet to show the world what kind of bull shit we deal with.
I love Mitsubishi as a customer, ducted with one ceiling cassette in my home gym, five zones, works great City Multi unit outside. Installed and serviced by a Mitsubishi Diamond company.
If you truly have a city moldy then you have one of their absolute best ones. And we're a diamond dealer as well.
What do you think of the P units /indoor air handlers? @@HVACRSurvival
I’m looking to get a couple of mini splits and I do have a little sulfur water.
How does the sulfur water effect these units? 3:26 Does water run through some units or is it more from the sulfur being released into the atmosphere from running the tap?
The gas enters the home from being drawn from the faucet. It travels in the air. If you do some searching for Sulphur water, they’ll give you the truth scientific name I forget what it is, but it’ll explain why this gas tends to attack, copper and other models.
Bet the other guy you talked to about the class was Ralph Wolff, he’s awesome teacher. We love Mitsubishi. That’s almost all I work on. We have awesome support, good training and good recourses
I would like to see he’s class! 👍👍👍
I don't like working on "them because I don't work on many of them." Really?
That must be a testament to their reliability. Seems like it's time for a new profession.

Good vid as usual ... Thx Sir ...
You should have called the video. I hate minisplits…..all of them ….😂😂😂😂😂😂
😂👍👍
Hahaha dude thats all we have here in Australia. When its all you know it ain't that bad.
Correct, I work on too many different things but my real complaint is the shit school they have and I wanted to call them out. I'm sure they have seen it by now. Hopefully it will cause them to address the issue. At the least it will have other techs looking for the same thing problems I dealt with.
@@HVACRSurvival Yeah fair enough man. I actually rate Mitsubishi very highly, and their tech support here is great. They're a market leader here along with daikin. We don't have gas central heating etc like you guys do, so it's all heat pumps big and small.
Great Video Bro.
Much appreciated 👍👍
@HVACR Survival probably can't answer this but is it legal that your company doesn't pay for callbacks? Or is it legal due to signing a contract? Just curious because I've heard you say that in some of your other videos.
I'm commission based on what the company bills. If they can't bill then I can't either. I pays better than being the optional hourly.
@6:43 ish....."lets pump it full of love" lol!! Indeed!!
What was the bill ?
I don’t know, why’s it matter ?
I hate multizone Mini Splits. Formicary Corrosion kills those evaporators. We fail all the time with the flares. The flares behind the heads bite us in the ass.
True, true and true.
What's the best 24 btu single unti to buy ??? Mr.kool ? My brother said this brand your working on is the best, is he wrong????
I hate all mini-splits but mitsubishi is one of the better ones out there. I said that at the beginning
Not a good advertisement when customers using baseboard electric over the Mitsubishi in the winter
Nope 👎
Mitsubishi cars are kinda abysmal too
um so if the coil is leaking .... what does recharging the unit do? It's still leaking right?
Correct it gets the air conditioning going again. It's not like it's going to leak out tomorrow, it did what I needed to do to get them by who knows how long it's going to take to get the coil and when we can get back. I actually try to take care of my customers unlike some of these scumbag sons of guns trying to sell them new shit 24/7 cuz they don't know how to fix anything
I found a brand new Mitsubishi American Standard 2 ton outdoor mini split. It’s the outdoor unit only. I’m looking for an indoor unit and wondering do I have to use the same model or can I use a different model for the air handler. My model is NAXS or NV series. I can only find models that are MSY or Trane NTXS. Do I have options or do I have to get the correlating air handler model???
Great video by the way
There are specific evaporators that work with certain outside units.
The No 1 reason i left Mitsubishi after 20 years ( contractor) : Leaks on indoor coils massive 😳
People think I'm crazy but they are not what they used to be. Maybe when they made them in Japan. ???
If they are using baseboard for heat instead of the mini split, they bought a unit from someone that sold them the wrong crap. Our mini split had no issues heating when the temp outside was at 3F.
You must not be a service tech and likely not an elderly person. I heard the same complaint from customers that purchased an high efficiency gas furnace when they first came out. Simply said, people don’t like change and if you’re on blood thinners everything feels colder. You’re also assuming that the customer picked the top options that they could’ve picked, that was not a hyper heat system so I would say you’re assumption is missing the necessary information to make factual based opinion.
I love my heat pumps, but I do wish they were a bit more DIY as far as repairs. Luckily they haven't broken yet over the 4 years I have had them.
Our Fujitsu is almost 13 years old no issue🤞 but I worry when it does it’s gonna be bad 😭
i wonder if you are in a house with the shoddy drywall?
the shoddy drywall would give off vapors that would degrade metals and would ruin air conditioners.
I think that started back when they imported drywall from China and let it dry on the boat ride over
Yea sometimes its better replacing but good tech support
I feel bad now. The number of those I used to spec😀
I actually was told by a young hvac tech that Mitsubishi are the best but I dunno after watching this
They are made in China just like most crap, but they are the best of the mini splits, I just don't like mini splits. Everything is proprietary... and unless you know their particular sequence of operation you're going to be lost until you figure it out.
Put in a 15k ducted hyper heat a year ago myself. best 3k dollars i ever spent and learned a bunch. No official training though LOL
You haven’t had to repair it yet 😁
@@HVACRSurvival I agree repair would definitely be more difficult than Install. Your video makes me want to buy a leak detector 😜
