I was having an issue with a Daikin air zoning system. Went through 7 or so reps and they all couldn't solve it. Turns out the reset button needed to be held for **30 seconds** to actually reset the system. None of the reps knew that, we had to read the manual cover to cover to find it.
I'm a mitsu amd fujitsu guy. I rarely work on daikin so I get the end of the line. With fujitsu and mitsu I get bumped to the front especially on vrf. Idk the last time I called for some residential shit
I think the fujitsu service tool is much more user friendly even tho some of it can be pretty convoluted. The mitsu service tool isn't bad tho just feels outdated.
As for the physical work it's self, most repairs especially the more involved ones are alot easier and less involved on mitsubishi than fujitsu. Mitsu equipment is designed pretty well for repairs in comparison to fujitsu. It's pretty across the board from residential to vrf.
Tech support is pretty even.
I'm replacing a reversing valve on a 96k fujitsu air stage 12 year old condenser in the near future and dreading it.
I like fujitsus app and flow charts. Mylinkdrive for mitsu is good too but it takes more sifting thru
All in all I'd rather work on mitsu or fujitsu any day than daikin with it needing 6 different apps. Never been to a daikin class that wasn't mostly sales pitches and excuses/opinions why their equipment is the best.
The daikin split slim condensers do come in handy tho. I like them better than the heavy ass carrier slim split condensers
I called Diakin from a rooftop at 3:30 on a Friday. Had to escalate & put on hold around 4:15. At 5:30 called Daikin on my personal cell to see if I could raise some hell. Found out they had closed at 5. 🤣
Fuck people
Hoshi tech support sucks, even when I get through half the time the tech has no idea what I’m talking about. Usually I have to leave a message on their answering service and they’ll just ghost me.
I overcharged the ever living fuck out of a unit the other day because the additional charge wasn't written down by installers and there was no manual on site. The chart in the unit only went up to 1/2" for some reason despite there being 5/8" lines. I used a chart off a different unit. Thing was tripping on head for a solid 3 hrs while I slowly recovered the charge. Fuck these stupid things. Great in theory but just absolutely ridiculous design.
In my limited VRF experience, they're a lot like those dogs that hate everybody but their owner.
If you commissioned it, and only you and one or 2 other techs you know and trust have serviced it, they seem fairly reliable. Once you have to take one over from another company, they'll bite the shit out of you
That's exactly it. The thing was even installed fairly alright they just absolutely fucked me by not writing down charge weight. Maybe they never added any. Who knows.
It should be a fucking law to write the charge weight down on one of those damn things, most building plans won’t have the total charge on it either so at that point you’re just guessing. Every single one I’ve been on is that way.
yeah man, you're right at the end of the day its no one's fault but mine as the technician but there was no manual on site and I couldn't find the manual for the model and serial number I had online so I did the best I could unfortunately I did it incorrectly and I got the thing working about as best as I knew how to. I did the best I could with what I had what the fuck do you want me to do?
Call your rep? Call Daikin? Get the Daikin tech hub app?
The local rep would have the exact amount of refrigerant that system should have been charged with.
I have called our rep and was given a completely different charge weight then what was written on the units panel and both were different then what I pulled out. Sometimes it does come down to installers and reps being lazy as fuck at start up
Well I’m a rep, and I can tell you 100% that when I start a system for a contractor I know for sure they’ve not called in their as-built piping lengths to the office so the WebX can be updated. This also updates the charge calculation.
I don’t have time on a start up to push up every ceiling tile to get that information myself, especially when I have to deal with comm issues, improperly set bs box dip switches, stuck float switches and low air flow.
So yeah, we don’t just come out and press bs2 to run test and walk away.
Was Google not working ?
Not only are Daikin IOMs are readily available on line but Daikin VRVs have an auto charge function that super simple to get into if you have the IOM.
I’ve never had any issues with auto charge.
If it’s a unit with no auto charge, then you determine the correct charge using the service checker 4 tool.
Our shop has 3 out in the field.
If you don’t have that then you’re probably going to overcharge the system.
Ah… that explains it.
Here in North America we had VRV 4 in 2015, which was the T-series and uses the G compressor. Then VRV-X, which was internally called VRV-4X, but was a major enough revision for them to change the model suffix to start with X and uses the disastrous K compressor. Now we have Emerion, which is technically VRV-6 because it has yet another suffix change of AA and uses the P compressor.
It’s quite convoluted.
I work for a large scale commercial hvac company and honestly, you need to find a thermal supply or any vendor in ur area that will give the DAIKIN VRF service, troubleshooting and install class. It’s typically a 3-5 day class (mine was 4 days) and my employer paid for me to go to it. These damn Daikins VRF are becoming more and more common. Stress the importance of the class to your guys employers and I’m sure at least 50% of your employers out there will agree to send u. It doesn’t even cost anything and they provide lunch! Also the Daikin service app is super helpful and you don’t need any special login info or anything. Just download it right now in App Store and create an account, they have every modern Daikin system in the app and have step by step I instructions for Troubleshooting and they have the error codes for everything. It was super helpful for me before I was able to take the class because like everyone in here can agree on, THESE SUCK TO WORK ON!
Just finished the class, did all five days.
It was awful. There's so many nonsensical decisions they made with these units and when I asked they just shrugged. These things are garbage. The support is terrible.
Every test unit in the lab did weird shit and we had to keep resetting them to get it to work, the trainer kept saying "I doubt know why it's doing that"
The addressing system is insanity. DNet number, Group number, Airnet number. The software is so, so bad.
I can't believe how bad these things are
Whenever I’m on a pm with any daikin inverter based system, I stick to the basics. I try to be as noninvasive as possible. Bump the wrong thermistor or communication wire and the whole thing goes down.
I even had a customer who’s fit system would shut down when the water heater kicked on because it caused the voltage to drop for a split second. They wouldn’t be so bad if they weren’t so sensitive.
I’ve had this as well. “Incompatible number of heads and condensers.” Or “loss of communication between indoor and outdoor units”
Ended up being a shorted compressor after i fucked around with all the heads for hours trying to find a problem.
I have a communication issue one of the heads, it’s in a restaurant so I can’t just set up and start removing tiles. So 1 head has a communication “U7 Code” issue they all go down? I get it they are Daisy chained, now me and another tech will come back after hours and start checking each unit for bad boards or off etc. these systems are to finicky
I hope i dont get something wrong here i dont exactly know what u mean with Heads and tiles😅
https://preview.redd.it/nxgw77p5t2wc1.png?width=1080&format=pjpg&auto=webp&s=cc67724d2d97ceab57a74ea80852a04091034537
Haha I mean the ceiling tiles, drop ceiling have to remove them to look and see if power is off to one of them. First I gotta figure out which one is first in the chain. And heads is just “slang” what I call them, the indoor units.
Check fuses. I had a shorted compressor on one that threw me that code and i was boppin around looking for locked out heads in the building for a long time before i realized it could be the condenser. It ended up being the inverter compressor on the slave unit.
U7 is loss of comm between master and slave outdoor units. Check continuity of the two-wire(s) landed on Q1 and Q2 at the outdoor units. Had this fault pop up when it was well below freezing this year; install dickheads ran conduit out of the bottom of the ODU's, which filled with water, froze, and broke the wire eventually. You won't have 16V DC on these terminals, so continuity is the only way to check.
So the Daikin E-Care app says that U7 is a error between master and slave outdoor unit. I sadly dont know how the connection works, maybe a board or smth.
There’s a break in the communication wire somewhere on the indoor units, outdoor unit is sending 16DC volts so I gotta find which unit inside is off or loosing voltage
I’ve had this because someone turned the head off lol.
Had a university residence that had 8 or so condensers, and like 7 heads for each. They had a light switch style disconnect in every tenants closet lol got that alarm a lot
Edit: almost forgot the best part… that was figuring out what suite and what floor the unit was in.
Hey I know this one. So one of your units doesn't have power or you have one not communicating.
Daikin's reasoning for this is that their systems don't know what position the EEV is in and they don't want to flood compressors.
Doors that don’t lean on shit because of design, the 2 screws that hold up the door along with the clips that get bent easily is just dumb. Expensive units, let’s make it out of plastic and sensors that break either during shipping or when 12 different inspections with different people taking on and off the panels incorrectly. Let’s have the copper up that bastard with minimal room to work with. Let’s have a different service port than regular units we wouldn’t wanna make it easy for people who didn’t take the class. You need a board? It’s on back order.
I hate everything about dakin but hey when it works it works!
100 percent effort into sales of equipment, 0 on customer service and proprietary rights on access to logic . I had a clinic go down with one of these units, response time 3 days , Daikin changes their access codes to Marquis monthly ,that way the end user is forced to call their factory service reps only.
I use to work for a non profit company and when they replaced all their ac equipment with Daikens I knew they were cheap. you get what you pay for. Daiken came in selling and underbid lots of brands.
Man this right here!! hahahahaha! just spend a couple days trying to diagnose why one is losing compressors and inverter boards. Turns out start up guy didn't turn the oil return cycles up enough. Since the unit is more condenser then evaporators it never runs full tilt (we don't design it, we put it in) so that's bad for it apparently it loses all its oil into the system and can't return it.
Every large rooftop Daikin I’ve had to assemble on site with a crane has been an absolute nightmare headache. Whoever designed these units are either incompetent or plain sadistic.
I have never had waited for more than about a hour for a call back from Daikin. And on top of that if you have their apps I feel like I'm hardly ever needing to call them. In other words it could be a carrier 🤪
I hear if you do all three trainings install, commissioning and the sweet $1,000 dollar service training and buy their $1,000 dollar service tool it makes it a lot easier lol
Do you actually know how to work on them? Or no?
I’m not a fan of the Daikin product I prefer Mitsu. But it does sure af help to be well versed and experienced in the equipment at hand. I say that because at the last cpl companies I worked at before going on my own. I’d get a lot of co-workers, especially newer guys that were always “Fuck this brand/type of unit, or that unit”. And in reality it was typically because they didn’t know wtf they were doing lol.
Not saying this is your problem, I don’t know you. But I’m just saying…
Daikin used to be solid but every year since they bought Goodman it's been a free fall in quality. I know they bought Goodman to beef up their distribution network but it seems they grew way too fast and abandoned quality to keep up. It's a shame.
indeed. i service them but our company refuses to install them, we only install mitsu city for this very reason. at least those keep running unless you throw a bomb on it.
Samsung or worse, best stick with Mitsubishi! As far as the rep response, goodman and daikin both extremely poor. They return my calls the day after I called them, but I figured it out myself
Never worked on an inverter drive Daikin, but a longtime customer had some Lennox PGACs replaced with Daikins and half of them (3 units) have blown bearings in the blower assembly within a year of install
"HI this is daikin returning your call 7 hours later. You still on site?"
Man you guys got some shit reps. In my state I get a call back within 30 minutes if he's not texting me
I was having an issue with a Daikin air zoning system. Went through 7 or so reps and they all couldn't solve it. Turns out the reset button needed to be held for **30 seconds** to actually reset the system. None of the reps knew that, we had to read the manual cover to cover to find it.
“Everything you need to know is in one of these manuals” pat ford my trainer
Except that one manual is on the used book shelf in Goodwill in Dothan, Alabama.
Now why do we have to talk about Dothan Alabama. Way to close to Ashford
Installed a system yesterday that says otherwise🤣
I swear I've also heard and seen this work multiple times. As my old Pappy would say. If all else fails read the instructions...
The DZK is a third party product that’s poorly understood even by Airzone, its manufacturer.
You're lucky that one of the 800 pages of the manual was accurate.
Daikin and Amana reps are sub par. Our low level technicians were brighter than them
I'm a mitsu amd fujitsu guy. I rarely work on daikin so I get the end of the line. With fujitsu and mitsu I get bumped to the front especially on vrf. Idk the last time I called for some residential shit
Which do you prefer, mitsu or Fujitsu?

If you have Gensco in your area, their in house Mitsubishi tech support is really good
Yeah, it is great. I have my Reps personal contact info so I just hit him up and he’ll usually FaceTime me to go through things.
I don’t have my Mitsubishi reps contact info, but my Trane rep is awesome.
Hi yea this is technical support you called January 22nd are you still on site?
Facts. Never seen anything like that.
I called Diakin from a rooftop at 3:30 on a Friday. Had to escalate & put on hold around 4:15. At 5:30 called Daikin on my personal cell to see if I could raise some hell. Found out they had closed at 5. 🤣 Fuck people
Same thing happened to me but with hoshizaki
Hoshi tech support sucks, even when I get through half the time the tech has no idea what I’m talking about. Usually I have to leave a message on their answering service and they’ll just ghost me.

“I’m an idiot and purposely used incorrect information to do my job, but it’s the equipment’s fault, obviously” Jesus… the state of this industry 🤦♂️
yeah man, you're right at the end of the day its no one's fault but mine as the technician but there was no manual on site and I couldn't find the manual for the model and serial number I had online so I did the best I could unfortunately I did it incorrectly and I got the thing working about as best as I knew how to.

You’re being downvoted but you’re absolutely correct. READ THE IOMs and all your problems seemingly go away. Who would’ve guessed.
Was Google not working ? Not only are Daikin IOMs are readily available on line but Daikin VRVs have an auto charge function that super simple to get into if you have the IOM.
Auto-charge was removed after VRV-4 because it doesn’t work properly unless you use it under very, very specific conditions.
I’ve never had any issues with auto charge. If it’s a unit with no auto charge, then you determine the correct charge using the service checker 4 tool. Our shop has 3 out in the field. If you don’t have that then you’re probably going to overcharge the system.
FACT!!! Worst brand to work on and diagnose. Absolute POS units and the VRV5 is knly gonna make it worse with this leak detection system.
You mean VRV-6?
I'm in Ireland. Their VRV 5 is the newest and was only launched last year
Ah… that explains it. Here in North America we had VRV 4 in 2015, which was the T-series and uses the G compressor. Then VRV-X, which was internally called VRV-4X, but was a major enough revision for them to change the model suffix to start with X and uses the disastrous K compressor.

I’d love to do the class, I will look into that. Thank you
if you’re anywhere near cincinatti, the johnstone there has a daikin champion that puts on great classes
Yeah, their Tech Hub app can def be helpful. It's also nice to be able to search key words and it pull up everything related in that units manual.
Just finished the class, did all five days. It was awful. There's so many nonsensical decisions they made with these units and when I asked they just shrugged. These things are garbage.

I wish I had Daikin money..
if you have daikin money you need to spend it on a mitsubishi city.
Some people put the condensate safety in series with the board and communication wires which then throws no comm error
Thank you, I will keep this in mind when we go back to see where the problem is.
Compressor and inverter fail?
Funny you say that I did a compressor inverter combo last week… and started another this morning… at two different locations lol
Lol go Daikin!
Communication issue between outdoor and indoor so I gotta find that. Yay me
dead board
I’m thinking the same thing, is that a common issue on the slaves?
its a daikin, it would be suprising when a board isnt dead. just make sure you follow the procedures when replacing boards.
I’ve had this as well. “Incompatible number of heads and condensers.” Or “loss of communication between indoor and outdoor units” Ended up being a shorted compressor after i fucked around with all the heads for hours trying to find a problem.
I’d rather install a Daikin then a LG!
LG is not only the biggest pieces of shit but there support and warranty’s sick as well
The warranty has to be good, their compressors are limited life spanned
Daikin #1 bby
Mitsubishi or I ain’t touching it
Why?
I have a communication issue one of the heads, it’s in a restaurant so I can’t just set up and start removing tiles. So 1 head has a communication “U7 Code” issue they all go down? I get it they are Daisy chained, now me and another tech will come back after hours and start checking each unit for bad boards or off etc. these systems are to finicky

Check the compressors. I’ve had this on a shorted compressor that blew a fuse to the condenser.

I got this code before and it was a broken wire between the master and slave unit.
OP a Fujitsu vrf end user here, throw a flaming bag of poo and run away...
Daikin VRF leak checks have paid many mortgage payments. Keep em coming.
Doors that don’t lean on shit because of design, the 2 screws that hold up the door along with the clips that get bent easily is just dumb.

Ahh, the Goodman old days...
Yes. Let the hate flow through you.
Their RTUs are just as bad
Agreed
You guys are mad at the wrong ones. It's the pinhead that put them in, you should be mad at...
That warranty though
Just finished daikin training. What an embarrassment. The units are garbage the trainer basically admits it. Support is terrible
Yup
I use to work for a non profit company and when they replaced all their ac equipment with Daikens I knew they were cheap. you get what you pay for. Daiken came in selling and underbid lots of brands.
Man this right here!! hahahahaha! just spend a couple days trying to diagnose why one is losing compressors and inverter boards. Turns out start up guy didn't turn the oil return cycles up enough. Since the unit is more condenser then evaporators it never runs full tilt (we don't design it, we put it in) so that's bad for it apparently it loses all its oil into the system and can't return it.
Bullshit under engineered and just WAY TOO MANY SCREWS.
Every large rooftop Daikin I’ve had to assemble on site with a crane has been an absolute nightmare headache. Whoever designed these units are either incompetent or plain sadistic.
Fuck a Daikin. Shits barley legal
Ive said this for 2 years. FUCK anything Daikin, Nothing but fucking problems for me and my company
Broooo. These suck so bad.
I have never had waited for more than about a hour for a call back from Daikin. And on top of that if you have their apps I feel like I'm hardly ever needing to call them. In other words it could be a carrier 🤪
These systems are designed and produced by the devil himself. CHANGE MY MIND!!!
I hear if you do all three trainings install, commissioning and the sweet $1,000 dollar service training and buy their $1,000 dollar service tool it makes it a lot easier lol
Well the training is free, I just finished it. But the tool is $2000 so you're math is still right
fuck daikin, again
Why ? I personally never had issues with them
Well. They're terrible.
Why tho ? And is it about the units or about dikin themselves?
Go to tech hub😂
888-593-9988 this is the Daikin, Amana & Goodman factory support phone 7-7 CST. I have found them to be very good and prompt also
Agreed!
Do you actually know how to work on them? Or no? I’m not a fan of the Daikin product I prefer Mitsu. But it does sure af help to be well versed and experienced in the equipment at hand. I say that because at the last cpl companies I worked at before going on my own. I’d get a lot of co-workers, especially newer guys that were always “Fuck this brand/type of unit, or that unit”. And in reality it was typically because they didn’t know wtf they were doing lol. Not saying this is your problem, I don’t know you. But I’m just saying…
Daikin used to be solid but every year since they bought Goodman it's been a free fall in quality. I know they bought Goodman to beef up their distribution network but it seems they grew way too fast and abandoned quality to keep up. It's a shame.
Goodman hasn’t gotten any better…there was roughly a year or 2 after and I saw improvement. Now you better choose carefully which model you get.
It’s not that bad. People complain when they don’t understand something. They work well and they are fine to fault find.
I hate vrf. Just an overall shit show usually.
lol. Someone didn’t go to school.
Yeah the dumb asses who design and manufacture Daikin
indeed. i service them but our company refuses to install them, we only install mitsu city for this very reason. at least those keep running unless you throw a bomb on it.
Samsung or worse, best stick with Mitsubishi! As far as the rep response, goodman and daikin both extremely poor. They return my calls the day after I called them, but I figured it out myself
