Nice job. To save on recovery, what we do is shut the valves to the system so we are only recovering from the outdoor unit. Then we put the refrigerant back after changing the compressor.
That’s no good
@@SteadyX-go4wc why??
@@SteadyX-go4wc show me where lg says that ! They have videos on here explaining to close those valves
Great video, brother. Just a few pointers since ( I've never used Teflon on Refrigeration equipment. Eventually, it was leak out of the Teflon tape will dry out and leak the oil . I normally use (loctite thread sealant (554) or nylog Refrigeration gasket thread sealant. Either one works great . Also, before re-installing the compressor threw in some Scavenger Acids neutralizer works great helps with the burn out . Also, next time, order some refrigeration isolation valve to place across the drier to isolate the drier, swapping them out after a week of running the system We normally start with an high acid removal core drier . We normally start with the (RC-4864-HH) core , and after a week, we go back and put in the regular standard core drier RC-4864 but in those type of system we also put in bypass valve to bypass the drier with verifying the oil is good . I definitely understand the headache you go threw working in NYC building
These are my favorite units to watch you work on. They’re pretty advanced.. good stuff my guy
Awesome. Glad you're enjoying the content. They are definitely very advanced & difficult to work on. This is a heat recovery heat pump so you can have heating and cooling at the same time. Thank you! Stay tuned for new videos every week🔧⚡️
Also, when charging, get yourself a hairdryer. Keep the refrigerant in the box, put the drier in the hole, where you connect your hose. You'll get the complete charge without out force operating the machine. Makes it much easier and faster to get total charge.
Reminds me of hauling all the crap up two floors to the top of the building of the hospital I worked in. Changing 20 hp fan motors what a job.
Nice work. Instead of turning the unit on to weigh in the rest of the refrigerant into the liquid side, now I just heat up the jug of refrigerant while the unit is still off so I know I’m not damaging the compressor. Then I let it sit for about 10 minutes then I turn it on. It flows pretty good with a good heat gun on it
You made a mess with suction drier lol 😂 great work jmt
I made a mess and cleaned it up. Now it's better than ever 😬🤣 That thing was so rusted. It was time to go anyways🔧
We use biflow and canned driers. It just depends on the customers. Most definitely on the burnouts. We are always testing oil samples for acid.
You sound pretty young,but seems like a real pro in your trade.
Few tips:
-Look into buying an apion kit. Allows you to pull the cores which makes the whole vacuum/recovery process much faster
-Eliminate your manifold while using the valves. Place one valve on the liquid and another on the suction line
-When pulling vacuum attach the micron gauge on side port of the apion valve then close the apion valves when performing micron rise test
-Use a heat gun wile adding refrigerant then start the system afterwards
-After you pull out the old compressor you should always drill into it and collect all the oil and complete a acid test kit. If its acidic, its always recommended to flush the entire system
Very good observations. I heard similar practices from AC service tech regarding the oil in the old compressor. It gives u a reference of how much oil to put back in the new compressor and if u can even use the old oil no acid shows up on acid test. If acid shows up then the lines should be blown out with nitrogen prior to install n starting new compressor
You are my hero straight up hardcore!! I'm new to the business however you inspire me work harder! keep up the good work God bless
Haha thank you! Much appreciated 🙏 Keep working and showing up💯 God bless you too. Stay tuned for new videos every week🔧⚡️
Makes me enjoy the weather here in TX.....been in the 80's for 2 weeks in a row. I used to live in WNY......yall NE cats can keep that cold weather.
I definitely don't enjoy working in the cold. The weather for this job was good. We were in the mid 40s.The first compressor replacement was 29 degrees. Now that wasn't fun at all. I need to go to the West coast for sure 🤣🤣🤣
Just thought I'd mention that the 14# written on the electrical case assembly is most likely the trim charge for the system and its associated IDUS/ pipework. You have to add that trim charge to the factory charge listed on the ODU to properly reach the calculated total system charge. This is all based on the design software "LATS". I would strive to remove that suction drier as soon as a oil sample passes, replace the cleanup cores until you achieve that goal and remove it. Vertical upflow/horizontal suction driers are bad in any application. The impact to suction line pressure drop and oil trapping will cause further issues.
You are my hero for hauling your van to that roof 😂
i learned something yesterday, check your indoor units for oil traps at the suction line, if they dont your compressor wil run out on oil.
So each indoor unit should have its own oil trap? Each 1 outdoor unit up here is connected to 8 or 9 indoor units.
LG is very clear about unnecessary traps, you cant have them. If you are accumulating oil in a IDU coil its probably an air flow issue or lack of refrigerant velocity through the coil to return the oil . The oil sensor on the compressor should initiate a forced oil return where the system goes into heating and blasts hot gas through to achieve this, if it doesn't it will alarm off after a fixed number of attempts.
phew hard job, even before the job begins (climbing the maze). great video JMT⭐️
Definitely. Just getting up there is a workout. Thank you & thanks for watching! Stay tuned for new videos every week🔧⚡️
Great Video, Great Job, Nice work. Thank you for sharing . HVAC in NY is nightmare ^_^. NO ELEVATOR ^_^
You're very welcome & thank you! Haha some locations are really terrible. Space is such a luxury out here. There is an elevator to the 8th floor but then we need to go up those staircases 😵💫 Thanks for watching! Stay tuned for new videos every week🔧⚡️
2:30 you don't have to go to the gym this way :) keep up the good work! thanks for the video.
Great job Jumper.
Thank you John! Much appreciated 🙏🔧⚡️
I like to cut under the braze joint not above, also try using a cable cutter instead of the pipe cutter way easier.
Did you determine why you are loosing compressors on this job? I was told that the compressors rarely fail on VRF units. I imagine it would be a nightmare to have a running burn on one of those systems. I’ve done those changeable core driers, that had five cores, for large systems. Do you test for acid, and change the drier cores until it’s clean? Looks like this wasn’t the first change out. Must be a good reason for repeat failures. I would dump the oil out of the old compressor and see if you have an oil return problem. That suction line drier looks like it was a major oil trap.
Good job, always enjoy your videos.Very informative.
Thank you! I'm glad you're enjoying the content & find the videos informative. Stay tuned for new videos every week🔧⚡️
Man this should pay you for lack of proper access hmmm good job the boss 😂
It's like going to the gym but you're at work instead 😂 There should be an extra fee for this😅💰🔧⚡️ Thanks for watching!
Nice repairs, HVAC in NY looks crazy having to bring all that up the stairs even the locations of some of the units. Interesting there's a suction dryer on that unit did they have an acid burn out before?
It's prolly been put in during install for future purposes of a compressor change out
Shoutout bro. From Hi - M solutek Abu Dhabi
I wonder how many of the lines on that compressor are for oil cooling?
have some questions with the nitrogen leak test. do you need to bring power back to the unit so that all EEV'S and solenoid open up? not too sure about eev's
but solenoid they close when power is taken out.
thanks.
Great content , love your work. Not trying to be negative but just wondering why you don’t sand the pipe before cutting it to try and keep possible debris from entering the pipe later. Keep up the great work Jumper man.
Awesome job!
Thank you! Stay tuned for new videos every week🔧⚡️
💪👍❄️🇺🇸 wow what a job. 💪💪💪💪
It was a serious job for sure. These units are something else. Thanks for watching & stay tuned for new videos every week🔧⚡️🇺🇲🙏👍
Suggestion. Use hand pull out tool to take out the heavy compressor.
Which tool exactly? Thanks
And nice clear 4k video! well done!
otimo trabalho , parabéns
You could probably sell a service replacing all the thermal grease with some kind of thermal pad that doesn't dry up or suffer from pump out
U can buy new bolts for those canisters at hardware store we do it all the time
Hi how much pressure you need at the nitrogen regulator, thanks
Finally some sun 🌞
Definitely better weather this time. Thankfully winter will be over soon! Thanks for watching & stay tuned for new videos every week🔧⚡️
@@JumpermanTech keep them coming i love the vrf content
@@prowesstv Glad you're enjoying the content. Looks like we will be busy here with LG!
Did you get board or maintenance people
The building provided the parts as they keep some stock there due to these units failing so often. Thanks for watching & stay tuned for new videos every week🔧⚡️
This is you're new spot huh ? Haba
Haha new spot for sure and they like the service so far 👍👌 A 3rd unit went down but it's not a compressor related issue thankfully. 3 in 3 weeks! Thanks for watching🔧⚡️
Domino effect 🤯
@@JumpermanTech Sounds like the rest of the units come next :)
@@svdleer We just lost another one today! This is getting crazy!
@@JumpermanTech sounds like limit of run hours is reached : fail now
Hello, im from mexico, how do you autoload?
How do u like being a HVAC tech in NYC?
Excellent, thanks for sharing.
Thank you & thanks for watching! Stay tuned for new videos every week🔧⚡️
Very hard to work with vrf
Definitely. Thanks for watching & stay tuned for new videos every week🔧⚡️
You will be working on these units several times per month, LG makes absolute junk. Inverter boards go all the time, you have a lot of units to deal with
if you loosing compressors on lg mv most likely your piping is downsize , check your header sizes twining the condensers .. good luck LG is piece of shit , I did tons of vrf system in NYc
