I also use a filter drier when im reusing the refrigerant. It is a company policy and i 100% agree with it. I also like that you added a liquid line pressure tap. I'd suggest when you remove compressors or have compressors with an oil port....do an oil test. I use and trust the Phase 3 from Nu-Calgon. Its another test, proof of an issue, and just generally a good idea. On our chillers, as part of the PM process we always send in an oil sample to be tested. It has saved many chillers from having a catastrophic failure. Great video as always Chris
I remember contacting Carrier a while back I was trying to replace one of those fixed Orifice units . Guy on the Carrier side told me 90% of the time it’s not the orifice that gets restricted. He recommended I replaced the drier and flush the crap out of the unit with NITRO that did the trick taking in consideration I only had a 2-3 degree temperature drop across the drier . I’ve tried the same thing on 3-4 units with success 🤷🏻♂️😀
Lol, "It means that the compressor was overheating for a long time...." Literally every compressor at my property looked like that when I arrived 5 years ago. 30 compressors and 16 condensers later, I only have 242 compressors to go! Yay!
Don’t know why I am here. I know nothing about AC units other than I got my home fan to spin with a water jet when the capacitor went out. These videos are awesome.
Great call proving and making a quick call on that drier. Where I've worked, guys would have called that a leak and spent a day looking for it, then to probably go to a clogged evap coil. Drier would be changed in the process, and we would have felt like heroes. I always hated working with people who just swap things out til the unit works. Your channel is an outstanding field teaching tool for newcomers and old timers alike. 👍 for that Apion Core Remover, best brand of core tools I've used, always worked smooth.
Based on how that compressor looked + the constant vibration, I completely agree it needed to be replaced. Also, love using the other filter to protect your equipment + clean the refrigerant as it is transferred back into the system. I have watched quite a few of your videos including some where the refrigerant was reused and don't recall seeing that treatment filter being used before. Perhaps you did it, but just didn't show it in the video.
Chris, I might be wrong but i think that the residual of the refrigerant left in the lines is what creates the pressures in the lines when testing with nitrogen.
My home A/C (a mini split bought in 2008) is running with this exact Liquid Gold now, and its main control board is fried because I didn't do PM to it, and high humidity from my humidifier just collected in it. (In China household, you have to do PM to your own A/C most of the time, especially living in the rural-city conjunction areas like me) And it is still running, using the jumpstart button on the unit, as the remote is completely useless. I don't want to change it because of the hassle no matter how small someone else thinks it is. I think some of your clients are thinking in the same way.
What’s the difference between filtering when vacuuming vs filtering when you are filling. Wouldn’t filter when removing so you don’t risk contamination in your tank?
Really enjoy your videos and tips. Very helpful. I wish that you would tell us which type of refrigerant your working with in the beginning. BTW I got into the hot/cold side later in my career. Wish I'd had RUclips back then. All the best, Sam.
Hey, tell them go buy about 5 of those portable ac units that have the external tube for the condenser exhaust and just vent them into the hallway. that way they can at least rent the room and have the occupants comfortable until you finish.
High amperage draw from the bad compressor caused the contactor to overheat and melt. Luckily there wasn't an electrical fire (judging by the looks of that contactor)

Is it possible the head was little high due to 110° Outside and hot and humid inside? And after it runs and catches up it will go back down to normal operating pressures as the building gets back climatized properly? Just asking sorry if this is stupid question.
I had a thought... You can use old compressors that you've replaced to teach your techs the proper way to solder a joint since the compressor is already borked, it doesn't matter if they burn it with the torch...
If there's a restriction in the system and is causing the head pressure to be really high, why isn't the compressor automatically turning itself off? Don't they have a high pressure sensor for a reason?
I watch your videos for entertainment and have a question. In regards to WHY the filter was plugged....considering the original compressor had extensive overheating issues in the past + a strong vibration now, it seemed to me the most logical reason for the original filter to be clogged would be due to debris (metal shavings, etc) clogging the filter as the compressor slowly failed. Since you didn't mention it as a likely cause, I am sure there is something obvious that I overlooked, but I hardly know anything about HVAC.
Quick question Chris, how are those appion core depressors doing? How long have you had them, do they leak? I bought a JB depressor but it leaked after the third use. Been looking for a good pair

Use a thermal imager, you’ll see an unacceptable TD across the Accutrols, anywhere from 1 to all of the takeoffs. Wax, varnish, & other contaminants are a known issue. Brand T knows about it too. Coming from a former Brand C Mechanic.
Couple of questions 1 what type of torch tip are you using and 2 if you are actively looking for a leak would you still only go to 150? I normally go around 400.
Nitrogen might not be all that Chemically Reactive, but like ALL materials, it's Thermally Reactive...AKA it expands when it gets hotter and contracts when it gets cooler...
Always check those carriers for condenser motor issues, u get a pressure trip which requires a reset and u get called back next day. It can restart like normal while u up there , but needs be checked for bearing issues. And always remember what NASA discovered in the 60s with astronauts in ambients over 95 degrees ,humans are 60 percent more likely to make errors in judgment. Can cause a misstep on top of an extension ladder !
I've seen R422B in units here in the states. Customer probably opted for re-using the refrigerant since charge was so close to factory, probably a cost cutting factor compared to throwing in 9 pounds of new 422 refrigerant. I've been out of service and on install for a few years year now, so I've yet to see the D variant of R422.
Yeah just lack of maintenance, I will discuss this on my Livestream on RUclips this evening 9/4/23 @ 5:PM (pacific) come on over and check it out ruclips.net/user/liveOz0hgO03xGI

great job,Does compressor 2 have a lock out for short cycling on high head ?
Yes
Have you ever used the recovery machine to pump refrigerant from the jug into the system?

I have a question for you can you run a portable ac for 15 hours nonstop with no rest cycles or will this burn up the compressor

What did the high head pressure on circuit #2 end up being?
shut the power off ASAP. cuz the ice in the compressor will burn or short circuit the compressor terminal if the ice reach that area.
Good old R22 systems what's a pound of R22 run these days last time I bought a 5 lb jug it cost like $350
My main concern would've been operating amps of the new compressor, pretty sure it's running at or over FLA with head pressure that high, no?
How does the app know whats the target superheat?
@2:13 The plastic on that relay is melted! That's a problem! Holy...
