Would like to mention to the new guys that when doing vacuums on isolated lines, that there’s a good chance you’re getting a little bit of refrigerant seeping through a shutoff valve somewhere especially on a larger system like that with multiple shutoffs.
Let's keep watching til the end and commenting on everything. He was in my recommends because I started binging on HVAC-R video's during the time I had no job and my now ex was taking care of us during the pandemic. I dreamed of one day being an owner of a HVAC-R or Electrical contractor but when you have to start at the bottom during tough times, no one wants to hire a 40+ year old and start from the very bottom even though i've been on the in's and out's of HVAC, and electrical field my entire life, I have no paper to prove it so they have to compete with me making higher wages stocking produce at a walmart with a decent benefit package(PTO, cheap healthcare, matched 401k, matched stocks, and free tuition for limited schooling like HVAC-R).
Nice job when I cut out coils I sweat and smash cup links on line so when you go back you can just unsweat cup link and put new one on don’t have to add pipe
Phew -- this is a tough one. There are about a half-dozen "push-pulls" (pump-in/suck-out) going on here, and I can't wrap my head around them when they come this fast through the "keyhole" of the camera lens. (But the on-paper segues are very good; they help a lot in these situations.) Have to go back sift through them one by one. TBC.
not sure if the way i do it is a good way of removing the refrigerant from one circuit but i close the liquid ball valve and change the sys. pressure set point to 5 psi on the cpc and i pull all the refrigerant in that circuit and then close the suction ball valve. then i set the pressure back to the way it was. not sure if my way is ideal but that is one way i was taught
If your circuits have ball valves on them That is a fine way to do it. Using your rack to pull as much Refrigerate Out as possible is a good way to do it. . The longer I work the more I realize there are many fine ways to approach things. Thank-you for sharing! :)
I believe somebody tried to put a leak putty onto the lines. Its like a get it through the night kind of putty where you can leak repair for like a day and then you have to come back and cut in cap for like emergencies I think that people kept on just adding more and more of that leak putty.
That's kind of a complex question. It really depends on the engineering build. But I would say an old system is a system over 20 years that is 100% always old. The system in the store will updated many times has the guts of a 25 to 30 year old system. But another example of this is Target. They have a much cleaner system as in the engineering is cleaner but not as rugged. So once a Target store starts hitting 10 years that's an old system doesn't need to be replaced but you can guarantee that it's going to have some issues at that point. Another example would be hussman protocol racks. These are small portable racks again not very rugged engineering when those hit 10 years those are considered rather old and will probably need maintenance and upkeep. Hope that adequately answers your question
If you did a true vacuum decay test you’d know there isn’t a leak that would be detected at 10 pounds. Bit of course I’m sure that vacuum didn’t get close to that.
I don't believe this is true I would be cautious of just trusting a vacuum test and opening the line personally. If you look at my gauges towards the end it did have 500 microns or 30 in of water column on my gauges. I recently did a single condensing job where a vacuum held fine. But as soon as I pressure tested it a whole blew and the evaporator coil. The store bought it secondhand if I were to put refrigerant in it without pressure testing it I would have blew 10 lb of 404a which is quite expensive. Also I have ran into it where your braises will hold in a vacuum great you don't have any leaks. A vacuum is pulling your brace tighter around the pipe wear a pressure test pushes your braise away from the pipe. I have had it when I was a new technician my braises were not fantastic and when I pressure tested it my braises blew a hole in them again they held the vacuum just fine. I am just a nervous Nelly and would rather not risk 1200 lb of refrigerant on something that I have had fail on me multiple times. Anyway that's why I always open the circuit slowly but you know I'm just some guy on the internet :) so do whatever you've learned your company tells you and you think is a good practice good luck buddy :)
I appreciate your willingness to share this; but, the rapid camera swings made me dizzy. Have to stop watching. The very beginning was ok.don’t know what changed. 5:54
Not sure really, So I have an agreement with my boss that my filming is not allowed to take time away Actual working so I do my best to film in a way That does not hinder my productivity or I will film on my lunch. I respect my employer This is kind of the best I can do without Violating my employers Trust. Thank You for the comment I will Try to keep the camera steady In future videos
To the fng's STOP "LIFTNG" (tm) (R) (copyright) Leave It For The Next Guy Came up with that my dayum self. This guy probably had David Pichette for a teacher. Meaning he's a #1 top tech from New England kihd. Keep kicking ass man you have a great mechanical mind. Always check EVERYTHING evrm the water heater for drips, cuz if you were there it's gonna be your fault if any problems come up. Don't need anyone Liftng on me 😂. 🎉 ps check out some of my quality fans 🎉

Nice video explaing a lot of new guys on the trade doesn’t feel confident doing this repair , it will help them
Looking at the condition of the evaporator , pipe work and other cabinets I would say the store is overdue a refit . Good video

What part of the country are you in? I work at Walmart doing refrigeration
Nice job when I cut out coils I sweat and smash cup links on line so when you go back you can just unsweat cup link and put new one on don’t have to add pipe
Thats a good idea thanks for the share !
I love your videos man I have learned a lot from watching them Thank you
Good idea 👍
Yes -- a nuance to remember. 👍

I'm glad the pen and paper parts are helping :)
Nice work👍👍 thanks for sharing!
I absolutely love your work and videos brother
Gold for a new tech (ur content)

👍💪💪❄️ Great vid. Is all that blue sediment the result of copper lines oxidation?
I believe somebody tried to put a leak putty onto the lines.
Its like a get it through the night kind of putty where you can leak repair for like a day and then you have to come back and cut in cap for like emergencies I think that people kept on just adding more and more of that leak putty.
Great vid man.
Buen video, Dios le bendiga, saludos desde Colombia.
good job I would like to know how to install or replace the temperature probes in the danfoss controller ?
Here is a video on a older model.
I'll make one on a newer 880 controller as soon as I can.

Nice job, I bet the other coils in that case aren’t long for this world either. Very through as always.👍
great work brother! I love you :)!!!!
Excellent information thank you
Nice job, what kind of rags are you using to protect the case? They seem pretty good
Just like the rag you buy at United Refrigeration by the Box. They're just soaked in water. :)
Iwould not recomend pulling vacuum since that is introducing moisture in piping! Leave it at atmosphere pressure.
Looks like the classic albertsons service deli case. Full of mold and coronavirus 🤣🤣🤣
There yummy........
Lol
great video goog job
Not even drunk do I put nitrogen in there to pressurize lines with a bunch of old valves micro-leaking everywere. Good one!
H10 Bacharach, thats some old tech xD

"Old store"... how old?
How do you know how old?
When do you start getting concerned about age? 5 years? 10 years?
That's kind of a complex question. It really depends on the engineering build. But I would say an old system is a system over 20 years that is 100% always old. The system in the store will updated many times has the guts of a 25 to 30 year old system.

@@gendronhvac-r1269
Yes indeed!
More nuances.
Thanks.
actually you should star pinch the pipes, meaning pinch it on three sides
@@leslieorm4905
Meaning pinch the end in the shape of an arrow?
I love Chinese food too

I can't believe there was no way to isolate that case normally. SMH
