Ran into this today. installed a Mitsubishi minisplit 10 months ago and the head units coil blew out. the damn manufacturer wants to send me a coil.. ridiculous! repairs on these things are a nightmare. I don't understand why they can't just warranty the unit but unfortunately that's all they would do.. I dread this repair
I did my first 5 head Fujitsu with rectorseal Pro-Fit pushin couplings on our home. So far 2 years later, no leaks. Not sure I'd trust those couplings/adapters on a clients home. It sure makes tying in the head units to the linesets. I still haven't tried to sell minisplits in place of "old-school" systems Maybe another year or two before I really trust the manufacturing/lifespan. But, I really think those Mitsubishi 1 way ceiling cassettes are a desirable product. Same goes for the push-in couplings. Hard to teach this 60 yr old dog new tricks. Thanks for you videos.
Thanks for this video. I have to do one Friday and this took the sense of dread away a bit. Same situation, under warranty, manufacturer won't replace the head.
I have an Electrolux Mini Split system, four units run off one compressor. One of the wall mount units has gone through three fan bearings and now the shaft has come out of the end of the fan. Sooner than spending more time and money to repair this unit, can I replace it with a different make? Can I disconnect it without loosing all the coolant in the lines for the other units that work well? Great video like your smart ass attitude
Cool flaring method with the drill but doesn’t debris gets into the lines that can cause restriction later on but I guess pulling a good vacuum should clean those right ?
Learning that charging by weight is not so difficult at all. Lastly, learning how these types of systems are maintained/repaired is also crucial as a DIY with skill.
Changed more than I’d like to admit . Unfortunately all were Fujitsu , but I think Manufacturer name doesn’t matter , weak copper is weak copper it doesn’t matter whose name is on the box . Let me know if others feel the same .
Hi, what are the symptoms of a leaking coil ? Just had mine cleaned after a small fire, now it's freezing up inside the unit if I lower it to 21c. Mine is about 15 years old, is it better to replace the whole system you think ? Thanks so much
@@TaddyDigest thanks for the reply. I just had it professionally cleaned by a company that puts the bag underneath and cleans it. I don't know if it's a coincidence but it's been frosting up on the coil since then. I wonder if something was damaged by removing the cover. I might have to have it checked by an AC specialist I guess. Thanks so much for your help
Question. My 18 K BTU mini split unit is in the garage. A tech found the indoor coil leaking. He recommends replacing the entire system. The current one is about 4 to 5 years old and I’ve changed the main control board 2 years ago. I’m not in a financial position to buy a new mini split. Please give me your opinion, is changing the indoor unit is a sound decision?
I replaced just the motor on a Daikin inside unit because of the noise and vibration it was making. Luckily you can do that without evacuating refrigerant on these units. My first job ever I guess lol.
use a torque wrench and too high on the nitro test pressure IMO. that low side test pressure is marked on the outdoor unit. I don't go over 350psig nitro. could cause a coil leak.
First thing you should’ve did was pull the cover and then the drain pan and the motor And wheel. The coil would’ve been super easy to take out and then put it back in the same exact way. I’ve got to do one tomorrow and it’s going to suck because the copper is in the wall. Idiot builders.😮❤😅😢😱🥵
Replaced a few coils , I found it’s easier to just replace the head
I agree 100 percent. Did one and will never again unless a must

Yes I rather replace the head because of broken plastic and dirty fan blade.

No animals were hurt in the making of this video. I repeat, in the making of this video xD
wires have to match evaporator coil and condenser coil polarity sensitive
Great video. Thank you for sharing

Hi thank you for help me to improve my career William from Ghana
Happy to help
u don't need torque wrench tighten until leaks stop then verify w nitrogen test.
Never seen a Flaring Tool like that, does any debris get into the line?

I would the system a good cleaning and check the charge

Stupid Question did you dudes removed the refrigerant before doing this ? Thank you
Mmmmmm......compressor LOVE flaring tool metal flakes!
I know this is what I need to do to fix my AC, just don't know where to find the replacement coil
Find a distributor of the equipment that You have and Then You will Find the coil.
Don’t forget your sensors in Clips
Nice job , but I would of recommend new indoor unit
coil was warranty
labor and refrigerant was about 600 dollars
much cheaper for customer this way
@@TaddyDigest
Understood 👍

Is the part under warranty?
@@TaddyDigest no. It’s 4-5 years old

Great job guys. ;)
Only requires working pressure for the test

very good my friend
Cool thanks for the videos
Your Welcome my friend

Typically 3 times your average suction pressure so 400 is plenty
Hammer mode with spin flare? That seems like a terrible idea 😵💫
Terrible terrible idea.
test motors by hand all the time
I had leaking coil on my indoor unit.
I just replaced the whole indoor unit.
I’m a contractor
that's a good idea
Much easier that way
You're Fu€k+& hilarious!! 😂🤣

I like I went to you give in, a comment, and the first thing it does is censor me censorship
Got to be cheaper and easier to just replace the whole handler instead of spending all that extra time changing out the coil etc.
600 too much blow a hole in the new coil

Lol why replace the coil? The cost of a new compared to doing the hours on the repair doesn’t make sense
Good question
The coil was under warranty
And the labor was six hundred dollars
A new air handler installed from our company would be $1500
Those Samsung units are junk!
Flaring Tool junk 100%
It worked for me you can see it in the video
Mikey pipes says they are junk lol. Gave it away in a video.
Good god I'm going to stop selling that Samsung junk
