- G’day in this video we are going to go through and show you how to completely stripped down the air conditioning unit, still leaving the refrigeration coil in place with refrigerant it. This is how we do a Defaul, that’s where we clean all the components of the air-conditioner indoor unit to bring the performance of the system back to original. When the fan gets blocked up with gunk, mould and dirt it reduces airflow, the reduced air flow reduce the performance, this usually happens after around five to ten years depending on the environment the systems is operating in and how much airborne dirt there is.

Very professionally done and documented clearly. Not many videos are done this accurately. Certainly the best way to clean the impeller. Thanks dude!
Hello. I don’t often comment. Finding a service of my exact model was a stroke of luck. I followed your video to the frame and completed the service. In Singapore this would gave cost hundreds of dollars and is what they call a chemical clean. Thanks again for the very clear and concise video. I am pleased.
You manage to dismentle the whole casing down?
@@francis_Teo_KY why not? It’s explained so well I’m giving it a crack this weekend.
Reassembling is tricky. Disassembly was easy. Now it’s a pile of trash. Thanks
Fantastic! Thanks so much. This is one of the best videos I've seen because it's very complete, you're super competent. Don't say more than necessary but say enough, illustrate everything well, not too loud, or fast spoken so easy on the ears, and this is difficult stuff to find.
Just uninstall everything minus the coil... Some homeowner wishes I would perform this cleaning service. It's literally cheaper for me to put a brand new head on the wall. Plus the liability of it all. Any little noise... you own it. Wild, thanks for the tear down video.
Very well done and detailed. My problem is I’m old and could not hear you or keep up. Nice job. Great video. I hope I don’t fuck it up.
Thank you for the best video I have found on disassembling and cleaning these units.
Awesome video. Incredible detail and I'm feeling confident in giving my units a way deeper clean than I have been after seeing this. Efficiency on point!
This is just awesome and explains a lot. I would have to hire a technician to help us with our Daikin, but it sure helped.
Great video. So much better than working in dark. I've just followed this except I didn't take the electrical thing out, just used bottle brushes and vacuum for the fan. The only improvement I think they could make to the design would be to be able to remove the fan from the left side. If it could be drawn out of the left after releasing the screw on the right it would be perfect. Anyhow that's me done for the year.
Wow this is amazing! Thank you for showing this in pandemic times which is especially useful. 🙏
Wow, great video and with the exact same model I have. You just saved me a few bucks. Thanks a lot..🤗
This is awesome! Thank you so much for this video. I wish the audio was better but I can see what needs to be done and how. I noticed the mold on one of my machines and wondered if the drip pan is not working properly? Now I can tear it apart and thoroughly clean it. Thanks Mate!
Yeah sorry about the audio it was a spare of the moment video
@@FullyAirconditioned Well you did an awesome job. Thanks again for your efforts.
I do the filter clean once or twice a year, nothing fowl smelling...yet! But this looks quite straight forward (QSF) ....but a couple of pics, some strategic perm pen marks and taping of screws to the part makes QSF into success! Great video!!!
Thank fuck. Someone that’s normal and know what there doing and not talking bull shit. Thank you.
Wow you are a lifesaver. Thank you for a great detailed video. I am most likely the least mechanically inclined human being and I was able to follow along with your video. The only trouble I am having is the last step where you state to push in on he plastic clip to raise the coils. I am not able to see a clip and afraid I’ll break the coils
Very well explained.... Excellent.... 👏👏👏👏👏👍 Thank you 🙏🙏
Awesome been looking for a decent video to clean my air con.
Reverse engineer way! Not disrupting the pumping down. awesome
Thanks for the tutorial, I only know about ducted inverter systems as I worked for daikin in Sydney. Haven’t a clue about split system only ducted.
Is that model ftxs60lvma ?
Great video, mine is about 10 years old and has the same problem. First video which actually shows how to take the a/c apart without opening the refrigeration system. I guess I will take mine apart tomorrow
All ways Lock out and tag out power supply. 👍🏻
Good luck with the work with the Daykin tomorrow and I am going to do a little bit of checking in to see if you have any other tips for the delay delay and delay amoung us. Staying with safety guys
This is how a “how to” should be done.
After doing all this work I can state that hiring someone to do is better😂😂.
Putting the machine back in the radiator is a pain in the ass, but everything went fine and I’m glad I learned a new skill.
Good video. I must say thats way more difficult than a mitsubishi they definitely have it down when it comes to ease of disassembly for cleaning
I have the same units. After taking the main cover off, I simply just remove the louvers and the fan angle pieces. Then I use a soft brush and manually turn the squirrel cage around. Does a great job with far less disassembly. Only screws that need removal are to remove the main cover.
If that works that’s great, only some of the units have the bottom louvre assembly that can be removed, we actually cleaned 8 indoor units from two multi head units, 4 of them this style. The larger indoor units were the one pice indoor units louvre, drip tray, backing fan frame one pice.this was the only one we video stripping apart. Thanks
@@FullyAirconditioned don't all these units have the drip tray and backing fan frame in one piece?
@@FullyAirconditioned I have a Daikin split unit I believe...the model # is FTXB12AXVJU. Is this the same type of unit, or similar you're breaking down for a thorough cleaning?
@@angelikashipman7697 by the model No, I believe your in the US, I would think it’s very similar .
@@angelikashipman7697 no not all, in this house it had a multi split system, actually 2 of them with a total of 7 indoor units. The smaller units had a removable drip pan, but the larger units had a one piece drip pan and backing plate. Not long after this model unit all they all went to one piece. But the newer models have reverted back to the separate drip pan, makes it easer to get to the fan and disassemble.
Thanks for this. Daikin is the only brand I’ve had that doesn’t give access to the blower wheel from the left side. Miss my LGs with easy access for cleaning. It’s horrid having to dismantle the whole unit every time. Your guide helps though.
It al depends on the model of unit, some Daikin’s do some don’t
So then how do u remove it?
Thank you very much!
Would be very nice if you could show this specifically with the Daikin Stylish Split Unit.
Thank you, thank you, thank you.
Now to see if you explained it like I’m poor 😂. Although that warning about the electricity has me worried, tell me you guys are in Melbourne so when I get to that bit I can call you to finish the reinstallation, the probable mould situation has me shuddering. 😢

Wish you were near Nashville I wold hire you to help me!
Thanks for this. I have a Daikin split system just a couple of years old that makes wind gush noises every so often in hot weather. Have cleaned it recently so thinking possibly sucking in water from the drip tray in high humidity because tray is dirty?
Some times the high wall units can make a puffing noise, its usually the fan cavitating, most commonly caused by dirty fan blade, blocked filters or blocked coil. It can also be increased when in cooling when the humidity is high and the coil is saturated with condensation water reducing the air flow through the coil.
Thank u.. save me money.. I did myself.
Very helpful
Thanks
Great work what model is this Daikin
Thanks
Amazing job very clear, will do all of mine the weekend have you got any videos on the outdoor unit that powers the split systems just cleaning inside
Also what do you use to get rid of gheckos when you can hear them in the unit
You can’t do much with the Gheckos, they crawl up inside the drain pipe, just make shore the pipework penetration in the wall is well sealed. Sorry haven’t done a video for outdoor, but it’s on my list. 👍🏻
@@FullyAirconditioned thanks so much for the reply much appreciated !!
I will read up too see if i can seal up the pipework with something on both ends
G'day, great video! Did you also clean the coil? If so, how do you go about it?
I have only had one unit that needed the coil cleaned, the indoor unit was in a commercial kitchen and was getting covered in grease. We pulled the whole indoor unit out and striped it apart and cleaned it. When the air conditioner is running on cooling its is constantly rinsing the coil with the condensation. You could brush it down or blow it out with compressed air.
Bloody legend.
Are all diakin model made this way where you can seperate the lower assembly?
Not all, but the most of the current model are like this
this i like
Great video. How often do you have to do this sort of clean ? A/C installer told me to just vac the filter/vent cover things every 6 months....
It all depends on use, how dirty the environment that it’s operating in and if the filters are keeper clean. This was two multi head units with a total of 7 indoor units, it was installed about 10 years ago. The dirtiest one was in the main living space, while the guest bedroom one didn’t really need cleaning, but the customer just wanted them all cleaned. Best way to check is by running your hand past the air discharge and check for dead spots. A dead spot would suggest the the fan is blocked with dirt in that spot. If the filters get very dirty or blocked the dirt will bypass the filter and block up the fan.
Thumb up...
Wow really well done. I need to do this cleaning asap. Apologize if this is inappropriate on your video here. Question: I have a mini split Daikin FTX15N Im getting 120v to the inside unit. But does not power on, is there a fuse on the indoor control board that you know of?
Hi Tommy,
1st you should suitable qualified to be working on high voltage equipment, electricity is dangerous, you can’t see it you can’t smell it, you can’t hear it and can kill you. I am guessing you are if you have measured the incoming voltage. Yes there is a fuse, but it’s soldered to the PC board. The biggest current drawing part is the fan motor, l would be guessing it’s a fan motor problem or a shorted diode on the board. I would be replacing both, we never replace a fan motor with out replacing the board and vice versa, good insurance policy. You could replace the board and the faulty fan motor damages the new board.
@@FullyAirconditioned Thanks for the quick reply. My Daikin unit FTX15NMVJU did have a removable fuse. That wasn't the problem though did a continuity test. I was getting 116/120v indoor and outdoor unit. Scratching my head I moved backwards to the 2 15a fuses with the pull tab. Tested in there got 120, however I should of got 240 when cross testing. Turned out one of the 15a time delayed fuses was bad. I just didn't realize I could still get power at both units with a burnt fuse. Hindsight I should of been testing for power the other way around. Meanwhile I pulled my unit apart pretty much exactly like you did cleaned everything to perfection. Spent 30 bucks on 2 new fuses. Problem solved.
Jesus they sure know how to design the most complicated things don’t they?
Very compact, but easy to disassemble on the wall, most other brand would need to be fully removed to disassemble.
Great Video
How much time would it take to do this service from start to finish? This is the easiest way I’ve come across to disassemble these wall hung units.
Thanks
Hi,
Depends on access and other factors, but should be able to be done in about an hour.
@@FullyAirconditionedthere's no there's no way when you take into account all the setup and everything else that you do that job. That's a half a day 4 man hours.
@@thomaswilson9254 the two of us striped down and cleaned 8 indoor at this house in less than a day. We also replaced a fan motor and bottom frame assembly, think the whole job cost was about $2500.00, customers was extremely happy with the outcome and how the units preformed like new. I actually went to this house to do a quote to replace the all the system with new equipment. Also gave the option to clean and fix the few problems as that all that was needed, some maintenance.
You have made so much work for your self , you should get any water anywhere near the fan motor , why dident you take out the scroll but it self and clean it ?
There is no need to take the fan and fan motor, just make shore that the fan motor end is at the top when cleaning so no water runs into it. But you can take out the fan and fan motor, just make shore its aligned correctly when reassembling it, keep spinning the fan as it goes back together to make shore it's not fouling on any thing.
I had tried to take the blower wheel out of the Gree 1.5 HP unit, but I didn't know how to do it. It seems easy for you but it not anybody can do it.
Gree air conditioners, like a lot of the Cheaper units are not friendly to pull apart. Daikin’s are made with the ideal of dismantling them while still on the wall and coil connected, don’t know many brands made like this.
Hey, that drainpipe, where does it go when the head unit is fitted to an internal wall? Just wondering where all the water goes or is it being dumped inside the internal wall as I'm in an apartment and can't see any drip pipes outside.
This unit that is mounted on the internal wall has a drain pump fitted, if it’s an apartment block there is usually a common drain pipe running down all floors in the wall to the basement.
If you ever hear an aggressive growling sound and your split shuts off to pump out the condensation from the reservoir, your condensation pump is full of crud and the pump is cavitating . Easy fix
Can the refrigerant lines withstand these stresses during maintenance?
From 08:15 the cooling elements are only hanging on the thin refrigerant lines. Couldn't this cause cracks from which refrigerant then escapes?
Yes we d ok this all the times me, with the larger indoor coils we use a cable tie or two, loop it over hanging bracket and throughout the coil end loops to carry the weight
Great video please speak up better for us hard of hearing people thank you
What could be the problem if an split ac unit has strong air flow on 1 side and less on the other? Even after servicing
open up the louvers while the units is off and inspect the fan blade to see if its blocked up.
How long do you need to let it dry before you put it back together?
You don’t need to wait too long as the indoor unit coil and bottom frame assembly usually are damp / wet when operating in cooling.
i have the same model but there is excessive condensation even after all is cleaned up. Any idea...?
It depends on the dew point of the air being cooled, if you live in a humid environment a lot of condensation will form. Most air conditioned will Achive a coil temp of 1 to about 6 degrees c, as air gets cooled below its dew point the moisture in the air turns from a vapour to a liquid. So look at your weather app as most will tell you the current dew point of the air. The air being discharged from the air conditioned will be between 4 to 10 degrees c. If the dew point was 15 degrees c, you won’t have much hope in stoping the condensation. What you can do is make air travel faster over the coil so it dose not cool as much, if the air travel slowly over the coil it has more time for it to reduce in temp, cooling it well below its dew point and creating a lot of condensation. if the air is traveling faster the faster the coil it will cool less and less moisture will be removed ( it will still have removed the same amount of heat from the air, just the ratio of sensible heat compared to latent heat will have changed). You will find it cools better and the energy use to turn the moisture into liquid is not running down the drain. Any surfaces on the air conditioned that are below the dew point will get condensation on them ( louvres, fan barrel) moisture can be blown out from the unit in really humid environment. Hope this helps
Did you guys remove the bracket behind the coil before installing. Else its impossible to dismentle the body.
Hi are you talking about the white plastic one that’s holds the pipes to the coil in place ?? No we don’t, you can get it out as long as you know how it goes in. It has a clip on one side of the bracket prise it off with a screw driver, can be very difficult when the pipes are tight holding the indoor unit hard against the wall.
Kind regards Craig
@@FullyAirconditioned cool. Perhaps different country different design...
What is supporting the metal fins to prevent the metal coil from falling down? It looks like some sort of pipe at the right side? Would the metal coil ever fall to the ground accidentally?
Cable ties hooked on to the backing plate on the left, and the connecting refrigerant pipes that run to the outdoor unit on the right are enough to hold the coil up. 👍🏻
@@FullyAirconditioned Is the refrigerant pipes strong enough to hold the metal coil forever and no damage the pipes? I guess not all have cable ties. Saw other videos they just lift the left side metal coil upwards to get the blower out and nobody seems to be worry about the metal coil falling down or damaging the pipes. Thanks
I guess you will just need to try, then you will know, with our actually doing it you have on idea, the pipes have more then enough strength to hold the 1.5-4kg depending on the size of the unit, being in the industry over 25 years, done this 100s of times never had a coil come crashing to the floor, it’s just not possible.
Kind regards
@@FullyAirconditioned Thanks for sharing
@@FullyAirconditioned If you pull the left side of the metal coil upwards or towards you, what is the maximum safe limit how far you can put out before the supporting refrigerant pipe becomes damaged or break? Thanks.
I have a question.
If i just let the coil hang on its own , is there chance that it gets damaged or a leak is created?
With the smallest size units you might get away with it, but the bigger units 100% need to hang it as you could damage the pipes
What does the green and yellow cable connected to the coils for? mine seems rusty
It’s the earth or ground, the coil gets wet so it possible that the screw will get rust on it, as long at it’s connection with the coil is good and making good contact. If it’s bad you could use a new screw and cable end.
@@FullyAirconditioned Thanks for the prompt reply! I'm currently contemplating in doing this small repair project as it seems like the blower fan's motor is starting to go out on me. No experience in dealing with electric , gonna shut down all the mains before dissembling and replacing the motor. Any advises?
How to clean daikin blower
Hi. My Daikin FTXS50LVMA was installed 4 years ago in a new house. Last week it started leaking underneath the and I found out that the whole lower draining tray is broken in pieces as well the air flow blades assembly. Is this normal for a 4 years old unit? Is there any replacement tray or is better to buy a new indoor unit?
Haven’t seen that before, if your unit was only installed 4 years ago then it’s still under warranty as it has a 5 years warranty from date of installation. You could call Daikin’s and see when it was sold, if it was sold more than 5 years ago you may need an invoice from the installer or dealer. The daikin unit are sold through the dealer network so it could have sat in there warehouse for a year before it was installed. Going back to your daikin dealer is the best bet.
@@FullyAirconditioned Thanks for the realy prompt reply. The Ac was installed by a contractor during the construction of the house a couple of months before we bought it and other than the manual I have no invoice or warranty card. As you said, probably was in the warehouse for a few years prior the installation. Just a question even though I might have to ask daikin, I've searched around to buy the indoor unit only but I didnt find anything. Do you think a similar unit will fit as a pair with the outdoor one?
@@emmanuelkottakis3884 You can buy the bottom frame assembly and a new fan scroll from Daikin’s spare parts, that’s your best bet.
I have an old Fujitsu heat pump and cracks in the drain pan were the first sign that it was leaking refrigerant - the refrigerant oil seems to degrade some plastics and cause them to become weak/brittle. Just a possibility to consider.
@@thromboid This is not the case. as FullyAir mentioned probably bad material or too many years in the warehouse as the specific unit has been discontinued.
😀it is very complicated cleaning. there is a cleaning method that does not have to remove the electrical wire first. you just need to get the roller blower.
Yes it very complicated and should only be do by someone qualified.
what a design error, a critical component of maintenance totally inaccessible without a complete strip down... should be able to remove the fan barrel like a dyson vacuum brush.
Yeah in a perfect world, but a Dyson is not fixed to a wall, with a ceiling 50mm above it, concerned to the others haft of the system on the other side of the wall. The major thing pushing the manufacturer is government regulation on how efficient the system is, except the US where they have a lower energy efficiency standards for ac unit made in the USA. This is actually one of the easiest units to pull apart, some brands need the indoor unit fully removed from the wall to strip it apart, requiring the gas to be recovered and recharged again.
Just uninstall everything minus the coil... Some homeowner wishes I would perform this cleaning service. It's literally cheaper for me to put a brand new head on the wall. Plus the liability of it all. Any little noise... you own it. Wild, thanks for the tear down video.
Did the house burn down when turned on?
Just joking
Not all daikin units you will have such an ez time
Practice helps
come work for me!
Thanks, 1st person I will call when I’m looking for a new job
Can I turn the power off in power box?
This should only be done by licensed experience persons, electricity is very dangerous and will kill you. I would turn off the power even if I was just cleaning the filters, you can’t be too careful. To work on this system we locked out the circuit breaker and tagged it out as well. 1st We checked that the multi meter is working by checking power on a known supply, then check the unit had no supply after the circuit breaker was turned off, we then check the multi again on a known power source. This is the procedure we follow to work in AC systems.
The filter's colour should be white. Much easier to know when you have cleaned it.
Hold it up to the light to see if you can see through it
well that's easy 😂
A1 not easy at all thank god i have Ducted Aircon Hell
For that job what is the cost of a complete clean.
#unintentionalASMR
These are the most annoying units I’ve ever had to deal with. I’m likely going to rip them all out for a furnace. The company that installed is charging $1500 per year for maintenance and $800 a year to top off gas. They do this because the units fault out and put out a half dozen error codes. So I can’t even heat my daughters room in the worst part of winter because these things freak out. Garbage.
That is ridiculous, they are ripping you off, get rid of them. We never top up gas, the unit has a leak or it doesn’t, it’s that simple. 98% of leaks are from poorly installed units. We would install close to a thousand air conditioning a year. We show the owners how to clean the filters and never see them again until there is a fault (maybe 10% of systems over the life of the unit, 15 years) or the units need a defaul, 7-15 years later blocked up fans like this one, it’s about 12 years old. You can’t top up this type of system, it’s critically charged and has to be charged by weighing in the correct full charge of refrigerant gas. No new gas has been added to this system in 12 years, it has its original gas charge from when it was installed . The company you are using should be using a vacuum gauge, be pulling a vacuum below 500microns, holding that low vacuum for 1/2 on hour with not rising above 500 microns, before weighing in a full charge of gas. Sorry, but your dealing with 100% dodge air company, you need to find someone else.
Have a look at my short, I show how to evacuate and vacuum gauge should be used, we do this on every insulation, 100% no leaks.
Great video BUT this is ridiculous. To clean this unit you have to take the entire unit apart The chances of breaking parts is almost guaranteed. There is no excuse that there is not a way to remove the blades (slide out for cleaning) to clean them once a year. The amount of crap mold mildew and other bacteria could make anyone sick. This is a very poor design.
No air conditioner is Desinger for cleaning, Desinger for cooling and heating. The Daikin would one of the easiest and simple to pull apart compared to other brands where you need to recover the refrigerant and disconnect the pipe work.
And why didn't you clean the exchangers? Half a job
Voice too low, noise too loud
Thanks, yep recorded on I phone with out a mic.
All good except camera men that is moving like he's gonna pe in his pants...
🤣
After watching. You don’t want to do this job
Best to leave to the experts, your HVAC guy
Great but speak up. No point giving a demo if we cant hear you
Yep sorry, didn’t have a mic set up for this one, it was a bit off spare minutes thinking.
Thanks for the reply. Nice to see someone still takes the time to read their comments 👍😊. Good video though.
This is way overboard to clean a unit. Clean the filters and your done. What you did can damage the unit and the coils.
Yep ok look at all the damaged coils on the unit we did this on, hang on, no damage to the coil 🤷♂️
@@FullyAirconditioned what was the purpose that you took it apart?
That junk is non serviceable. When it gets that bad, it's ruined. Your going to break something and cause more problems that you will be liable for. It's cheap junk. People that people that put these in their shops are ridiculous also. It must be kept absolutely clean and dust free
The units in the video were at least 10 years old, we striped down and cleaned 8 indoor units in less than one day. We also replaced a fan motor that had a noise bearing and a bottom frame assembly as the louvre linkages were worse out. All the units were back to original air flow and heat cooling capacity, customer was very happy, might see them in another 10 years. You must be from the us, seams like you guys don’t like split or multi system over there. Your laws on efficiency or air conditioning units is set far lower than here in Australia especially units made in the us as there efficiency are set even lower again. You basically can’t sell a DOL start compressor ac system here, so the system we have in Australia are basically all inverter compressors. A split system is more efficient, quieter and costs less to run than the flinstone engineered equipment you guys have in the us. Yes it will need a strip down and clean every 7-10 years but that cost if far off set in the running cost savings.
How do you clean out the drain hose/tube? I believe I'm having a problem with proper drainage...also, Is it common for mold to grow inside of these units and how would you prevent that from happening? I do appreciate this video great work, and hope you're able to help me here I'm about to tear it out and put the whole thing in the trash though, they do not provide adequate air filtration and I can't find any add on filters to install. . &Myairconditionerskillingme
You can feed a small clear tube 6mm to 8mm down the drain hose through the front of the unit via the drain tray. Open the cover, remove the filter and feed the tube down the drain hose via the drip tray . We have attached the tube to a water drink bottle before , then you can squeeze the bottle to force water down the drain. You could also add some bleach diluted with water, this will kill the mould spurs, but be careful as the smell of bleach is not pleasant and can last a long time. You could use tea tree oil, it’s a disinfectant and has a pleasant smell that is short lived. The filters in an air conditioner img unit are to clean the air to stop the coils getting blocked up. I would recommend getting a air purifier, there primary function is to. Lean the air, most have many different layers of filtration, partial, electrostatic, carbon, hepa, and ionisation, split system filters are no match, an air purifier is what you need. We installed the daikin one in our office and it 100% better air quality, has removed smells and there’s less dust, well worth it. It also comes with a couple sets of filter.
Thanks
Thanks
