Another great one Curtis but I don't consider that system a true mini split system. But God bless you for being willing to fix it and get it running correctly. Even with the air handler hidden behind that kraft faced batt fiberglass insulation which to me is still a no no. Hopefully the weather cools down In Georgia soon. It has in southeastern Pennsylvania but humid again. Now hopefully soon you will post actaul mini split repair vidoes soon.
Difficult repair, tight spot !Good job man thanks for the video i had been trying to find one of these repairs without success, keep up! These units don't require a filter drier for some reason, that was a muffler as you mentioned
Nice job, a couple of hiccups, but that happens. I'm getting to where I like the mini splits less and less. Circuit board with integrated capacitors, no thank you, and I am pretty good with electronics. I like simplicity, I guess I'm just an old fashion boy. Don't tell anyone, but I couldn't tell you how many dryers I've tossed in my day. I never had an issue with any unit I did that to. When you pull a vacuum, it evacuates the system of all moisture. Well maybe I was just lucky, but I did it many times.
I have a question, I've heard this described before as three phase. Isn't the compressor DC (inverter)? If so there's not phases in DC. I'm just confused.
this is what the internet says: The motor is a permanent magnet synchronous motor or a switched reluctance motor. They are technically 3 phase motors with the inverter being powered by single phase. The 380V DC is actually the bus voltage that is then chopped up into a sine wave to power the motor. The inverter system is basically a VFD. @@theguyjt7921
In close quarters like that back line, I use the real small torch system . Even the largest tip on that woll produce a small flame, bur hot enough to work the brazing material aroung the joint. You don't have to worry about burning anything and it really does make a noce clean joint.
@@gslofts1763 this is a multi zone unit it seems. A single zone pioneer for single, I think the whole thing can be had for around 700 bucks, indoor and door unit.
I’ve installed a ton of ductless units but thankfully I haven’t had to replace any refrigerant side components. Was it difficult to diagnose this failure?
While at the Carrier distributor we got on the subject of mini split repairs. He heard that they don't repair in China. They just replace the entire unit. Probably ¼ the cost of our equipment.
@@zunar_j5_933 That's possible, but since the one in the video has an orange top rather than yellow would indicate it is not approved. I purchased one from Amazon that was advertised as DOT approved and promptly return it after seeing that it had no TW, WC or DOT markings on it. Another glaring safety flaw was that the valves stuck up above the handle.
Well if pointing out that a made in China piece of equipment that has the potential to kill you has not passed safety standards makes me a Karen I will own it@@Miketime969
Gree is great a little priecy in the USA due to greedy distribution, i have had great luck with midea which is who makes 90% of the random ones on ebay and amazon. Too many old school hvac guys with fear of china mini splits , midea makes them for carrier etc also! Curtis what did this compressor do? Was it dead or rattling or not building pressure?
AC is something most people take for Granted 🙏 until you Don’t have it or feel you Can’t Afford it. 🙏 Extreme Heat Wave across the US this Week is Deadly. 🙏
@@uzlonewolf can you explain a little further, trying to grasp the idea... Is the compressor not DC? As I understood, incoming AC goes through a bridge rectifier and is inverted to DC. Once DC, IC controlled switches are used to ramp the compressor up and down. Is this not correct?
Hello Curtís, that camera you’re using is not very good, the quality of the video is poor, kind of blurry. I thought I’d let you know. I always watch your videos, I love them. I have learned so much from you, like you couldn’t imagine. I hope you can take care of the camera issue
Nice effort there on the compressor install. We learn the trade one system at a time eh? I do not use nitro when brazing. Never did. No clogging of any particles either or whatever they try to tell you. Just use it for pressure testing. Usually if there is a can on the hot gas, its a muffler for noise control. Nice vid.
Should use nitrogen on all Connections, the new systems have very fine strainers before EEVs , they will stop up High dollar machines now need extra procedures to insure proper performance No Hacks
Those vevor tanks are junk. I had one leak. So I took it apart and found that the liquid tube doesn't go to the bottom. Actually 1.5 inches from bottom. Also it was partially broken at the threads where it connects to the upper valve. Trying to save 50 bucks is not worth it.
So what if any shavings got into the old junk compressor. And as far as any in the tubing,I might of fished around a bit.With a q -tip and a drop of oil on it. But I'm with the big guy,on this one. Why not ? Good job Curtis 👍
Always cut discharge line on scroll and rotors compressors they have a check valve on discharge in compressor to prevent them from turning backwards when they cycle off and it could trap refrigerant there and you won't unsolder any more after that pressure. Gets relieved while in soldering and shit ball of fire comes out and burns your head
@@Miketime969 This was not a stupid question as I think it would have been easier to just replace the whole outdoor unit VS. brazing in those tight spaces of the modern mini-split unit Also the only stupid question is the one not asked.
Make life easier on yourself & take 5 minutes to remove the electrical & panels surrounding the compressor. While you were doing recovery that would have been great use of time
Thanks for bringing us along Curtis. It’s nice to see something different than a typical split system or a pack unit compressor changeout.
Nice work Curtis.
Awesome Video! My Heart Sank when you First Started the Compressor! Well Done.
It's nice to get some of those high profit jobs from time to time!
Another great one Curtis but I don't consider that system a true mini split system.

Good ole power companies and the “ New” improved meters where they can shut it off with a key stroke back in the home office. Nice repair Curtis.
Pay your bill and your power stays on, simple concept?

Same here. I despise working on the mini's. They need to make the danged things better.
I tried your board swap technique on a pinball power driver board today. I had to cut some zip ties to make it happen
Good job. From what I remember those inverter compressors are 3 phase, I know the carrier ones are.
Yes they are

The IPM makes a simulated sign wave with DC pulses.
Don't care how you done it but you got it done ... Good vid ... thx Curt
29:38 Dodged a bullet there, dintcha Curtis?🤣
Yeh there was a , “thanks be to god . “ moment

Nice work. That’s looks like a rotary compressor
It is
A nice clean job Curtis 👍 Au
Thanks 👍
Curtis, what did this job cost to replace the compressor? On some of these units, I’m wondering if it’s cheaper to replace the entire outside unit?
It's not cheaper to replace the outside unit.
@@gslofts1763 this is a multi zone unit it seems. A single zone pioneer for single, I think the whole thing can be had for around 700 bucks, indoor and door unit.
Good question fujitsu send new board with compressor i think
look like there was a lot work go on. but find the problem and got it fix. be bless and do not get to hot.

When I work on those units I just take all the panels an fan out to make it easier. Good job .
Why didn’t the capillary action suck the solder around to the back the first time? It didn’t get hot enough?
have you ever considered buying one of those brazing hooks or a brazing "c" tip?
Yes
Kind of surprised to see you using a Vevor recovery tank. Unless they changed them recently they don't meet DOT regulations.
Karen
Don't think that applies to all Vevor tanks. Just some models.

Love your vids Curtis!
If you were to install a mini split unit, what brand would you go with?
Gree
Gree is great a little priecy in the USA due to greedy distribution, i have had great luck with midea which is who makes 90% of the random ones on ebay and amazon. Too many old school hvac guys with fear of china mini splits , midea makes them for carrier etc also! Curtis what did this compressor do? Was it dead or rattling or not building pressure?
Mitsubishi or Gree
I've have started using bubbles with the little brush not so messy still have the spray
You recover through the vapor side of your tank sir?
Hey Curtis passing the great state of Georgia tomorrow, how far are you off 95
An hour
Thought you have to close the ballast to get deeper microns...
What size tip is your normal brazing tip?
A 3 I think
Closed caption is grayed out. Please turn it on. TY Daviid
Will do. I have to wait on UA-cam
Would it be better on power bill to get a 3.5 ton gas unit or buy mini splits?
What is the CFM rating on you vacuum pump? Thinking about buying one and I just wanna know what you like to use.

AC is something most people take for Granted 🙏 until you Don’t have it or feel you Can’t Afford it. 🙏 Extreme Heat Wave across the US this Week is Deadly. 🙏
Why are these called inverters?? They weren’t around when I did ac work
They basically have VFDs built in, so incoming power is rectified to DC before inverting back to AC at a variable frequency.
@@uzlonewolf can you explain a little further, trying to grasp the idea... Is the compressor not DC? As I understood, incoming AC goes through a bridge rectifier and is inverted to DC. Once DC, IC controlled switches are used to ramp the compressor up and down. Is this not correct?
There should be a strainer in the system
They are very fine mesh and should always purge with nitrogen while braising and pressure testing
No kidding, good luck on getting paid on that job. Don't to a check 😮
It was for a property management company

It looks li I e you have your truck emptied out on the lawn there.
Not much room in there 😳
Did you get paid? I'd bet against it.
Cut it open! Dissect the compressor! Lets look at the anatomy! We want blood!!!

Did you really use a multi tool to cut the copper lines lmao, o.o, I love your videos but idk about that one buddy, eek
Why not. There was no way shavings could ever get in system. Cut piece was unbrazed. So, why not
Either that or a angle grinder.
yeah, hate for shavings to get into the blown up dead compressor LOL
I didn't say anything about shavings, I just said idk about that one, don't get too triggered. Just not the way I would have done it.
Great Video but a Compressor going tits-up with not hardly any hours on that unit would make me avoid a mini split!🧐
It’s an older system
Gee, hopefully she’s able to pay you for the repairs you did.
It was done for a property management company
Cutting the line with that saw seems like a real bad idea.
There’s no way any shavings could’ve gotten into system. It made for a cleaner job. Why not .
@@HVACGUY- that saw - while cutting through the big pipe - sounded like some music Jimi Hendrix dreamed up way back when. RIP Jimi!

Sounds like it's running wrong rotation
Almost as much work as regular split . Paid power bill dang hope you were paid.
Why not just replace the whole outdoor unit?
Why ask stupid questions
@@Miketime969
This was not a stupid question as I think it would have been easier to just replace the whole outdoor unit VS. brazing in those tight spaces of the modern mini-split unit
Also the only stupid question is the one not asked.
Nothing hard about it
@@Miketime969 Alright Karen!
@@Peter_Yachymczyk that’s why you will always be poor and struggle because you take the easy way out in life
I only work on mini splits I that I sell I will not install a mini split in a M H
Make life easier on yourself & take 5 minutes to remove the electrical & panels surrounding the compressor. While you were doing recovery that would have been great use of time
glorified window unit even has the same comp youd see in a midea window unit lol
