Love your videos man. Been in commercial for a year now and been doing my best to educate myself on these chiller systems. These videos motivate me so much!!

[@shanek923]

A big thing to with the bigger equipment from my experience is everyone wants a well seasoned "chiller mechanic" and companies don't wanna put younger guys with the senior or actual seasoned mechanics to teach them... you can get into it without that but it's a bit more difficult... also hats off to you for wanting to teach and explain alot of this type of work

[@Interestinglybored209]

I do not get why companies do not want to put senior guys with apprentices. Its super ridiculous. We have a senior chiller mechanic who is in his 60s about to retire in 3 year and he for the most part works alone.

[@shanek923]

@@Interestinglybored209 doesn't make sense and once he's gone they will throw someone new on that work and expect them to know everything or just lose the work all together

[@kakawett8362]

Sometimes the old tech has so mu h ego he thinks he is the only one that can do the job and doesnt want to teach to anyone. I've seen this ego so many times.

[@Interestinglybored209]

@@kakawett8362 that also true sometimes. In thus case i believe our management is just sloppy. They make good money they could care less about the future techs and how to be more efficient in production

[@royamberg9177]

The biggest thing keeping a tech from moving forward is lack of attention to detail. You do a very good job on that. Keep up the good work

[@frostwave.]

I say this very often to my colleges, the problem is never putting a machin together. It's alway the last 5 to 10% which make the differnce between a good running chiller and one with Problems from the (re)start.

[@cranialdiscomfort]

Damn brother this is an educational page. You've taught me so much in the few weeks I've watched. Can't wait to start at the chiller team next week. Thank you for the pep talk!

[@HVACTIME]

Welcome to the chiller side!

[@mikegolmon8375]

Great encouragement speech. I was so overwhelmed in the beginning it froze my ability to just get with it. Much better now.

[@spikester]

This is good content, you indeed have a natural gift for off the cuff voiceover while recording to explain your expertise in english while we watch. Indeed these jobs can be so unpredictable but thats what makes them so interesting, never know what you're walking into. Keep up the impressive work.

[@stratosgiannis4340]

Holden, thank you! Appreciate you and everything you do! Cheers!

[@paulmcelvaney4148]

Worked on more than a few YK's in my life, not so much anymore, but great video and good to see. Now I am more on air cooled, but kinda wish I go back into the water cooled. I remember the older YK's had the oil sump below the condenser, so it was a lot easier to remove the oil pump. keep up the good job!

[@johntodd9290]

Chrysler chillers had brazed tube sheets. Happened a lot year ten on. A Vilter job we had the tank truck came on Thursday. Lol.

[@reyrodriguez1005]

Love your videos Man. Definitely learning a lot from you

[@cosmokramer5421]

Absolutely great stuff man. Keep it up. Your videos have helped me tremendously. I hope one day to pay it forward. Thank you.

[@EverythingHVACR]

Always great information, Nicely done Holden!

[@larrychristopher9147]

You've got a really positive outlook. Trouble is finding people that want to learn. I believe you to be highly intelligent person, but I also think you overthink stuff a little. Good luck with your career

[@HVACChillin]

This video drop couldn’t come at a more perfect time. 🤙🏼

[@HVACTIME]

You got this bud!

[@burningdust]

Hats off to you; I work in telecom electrical; big sites, huge cooling requirements. everything must be redundant. Our mechanical rooms are nightmare fuel. I’m fascinated by the engineering of the chilling systems and admire the brave people who service big gear like this.

[@hansmuller1625]

I used to work with cooling such places. Our point was to keep it simple, everything was always redundant, but there are often simpler ways to do it than what you usually see. I have taken those principles with me to my current employer and i'm happy to say we're improving both in simplicity and redundancy.

[@burningdust]

@@hansmuller1625 that’s awesome your experience in telecom afforded you some benefit later on. I can see how it might. so many times I’ve looked at a setup and thought.. there has got to be a better way. It seems more often than not we end up dealing with hvac companies who aren’t familiar with Telecom applications, hell even getting the point across that “it’s not about human comfort but rather what the equipment needs” can be a challenge. I hope that one day we can find someone who specializes in telco hvac .

[@hansmuller1625]

@@burningdust Indeed. You can tell when a "regular" hvac company has had a crack at such a place, often with the aid of a consultant. You get valves, failovers, and all sorts of complex automations that are supposed to shift the system from one state to the other. Well sure, but when you do that you introduce lots of components that bring with them a whole slew of new failure points and modes. On a project that we never ended up doing we calculated two turbine chillers that would each run at 50% load in a normal case. That partial load combined with low ambient made it so that freecooling became unnecessary, and in case one chiller failed the only thing happening would be the other one ramping up, and the only cost of that would be in efficiency. The project became cheaper, efficiency in summer time higher, maintenance costs lower, and without sacrificing redundancy. While doing all this we can also introduce the challenge of making it energy efficient. That's a whole other story but a fun challenge.

[@takethe101totarzana4]

Good stuff. Looking forward to the next part.

[@HVACChillin]

Great video Holden. Your advice was on point.

[@briansmyla8696]

Did you consider replacing the bolts on the flange that was leaking? If the weight of the sump stretched them enough to cause the o-ring to leak, then I wouldn't trust them to not fracture at some point down the road. Cheap insurance.

[@HVACTIME]

Would have been a good idea... Why couldn't you recommend that 3 weeks ago?!

[@briansmyla8696]

@@HVACTIME Hey, I just found your video!

[@troydemers3268]

Torque specs on the leaking flange bolts?

[@rodgraff1782]

Ever work on natural gas fired absorption chillers? Do you still use a hockey puck to temporarily replace the rupture disc when pressure testing the chiller?

[@HVACTIME]

Ive not worked on absorption chillers. When i pressure test low pressure I dont exceed 8 to 10psi so I dont have to mess with the disk

[@sterlingarcher46]

I get what you're saying Holden but over here getting into centrifugal work is very difficult. The few companies that do work on it usually only have 1 or 2 guys who have it on lock and try to keep anybody else from getting in , because they wanna be the only ones and therefore have leeway and power over the bossman . I dunno if it's the same elsewhere but unfortunately over here there are a lot of politics getting in the way of one's career trajectory unfortunately 😕

[@akidos9300]

How often do you come across hitachi chillers ?

[@AmericanLocomotive1]

What was unclear from the original video is why the chiller was down for so long. Was it a planned shutdown for overhaul?

[@beaverdamservices]

How much money is all that refrigerant?

[@johnwayne2260]

Conspiracy theory: he never lost the refrigerant, it was all around him the whole time…

How long did it take you guys to get that oil pump assembly? I've been waiting on one since March. Still not in.

They have their purpose, channel locks are good for those stupid spring-loaded hose clamps that are on everything now, the ones that rust & break when you sneeze at them funny after a while.

[@mynamesdan2164]

This guy uses teflon tape like hes stopping all the leaks with it!

[@HVACTIME]

I don't understand what your trying to say?

[@mynamesdan2164]

Lol you use a lot of it! When I saw it I was like HOLY! That thing will never leak haha! No hate here pal, just thought that was funny! I’ve never worked on something so massive but it seems like a pretty satisfying job, I appreciate you making it seem possible for me and anyone!

[@HVACTIME]

Gotcha lol, ya can't have to much Teflon! Thanks for watching!

[@coldfinger459sub0]

I hope I never lose 1300 pounds of refrigerant on one of my jobs. But I would like to say I was in that bracket of where I sell equipment at the price range that needs 1300 pounds The largest piece of equipment I’ve ever put together is just under 100 pounds. That would still be a bad day if I lost it
