Never Seen This Happen I Messed Up

[@jericosha2842]

Honestly I love when you guys show mistakes. I'm really hard on myself and this stuff helps bring me a peace of mind. At least you know in the future and you taught us something too!

[@jesuss4437]

C&D makes some self piercing saddle tap valves that would have helped a lot in this scenario. It’s good to keep some in the truck so you can gauge up on your first visit.

[@ReliableHVACR]

Good to know, I'll look it up. Thanks for the tip

[@jameshendry9906]

Good video!!! Most guy watch these video to learn or at least I do. Don’t get me wrong some are entertaining but for the most part it to help us be better techs. Kudos for you on showing everything even mistakes it One of the reasons why I like watching you you’re authentic. Keep up the good work

[@marcoferreira226]

Well done Buddy, who doesn't make mistakes. That unit is working it's on it last legs

[@chicanoazteca8614]

That makes sense. When I saw you pull out the port, it looked like it was completely blown out. I was wondering why the entire charge wasn't lost. Didn't make sense to me, but after you said the gasket was somehow inside and creating a blockage that made sense. Never seen that one before! Those damn ports always leak. I do the same and just throw a brass tee on them. Cheapest and fastest solution to that problem!

[@JayyCayaxFG2]

On the Those units theres usually always a label with refrigerant type and how much inside the compressor panel. Its the one on the bottom right on it. Just a little tip to know. 😊

[@ReliableHVACR]

Thanks 👍🏽 I know they're usually good about putting the model/serial in several places

[@stormeagle28]

These many different electrical systems in the US (like this high-leg delta system) are always fun. Here in Germany you have 230/400V. 230V phase to ground, every household single-phase outlet has that and 400V phase to phase. That's all you get, you don't get less than that. You don't get split-phase power out of a three-phase system with this fancy neutral point connection and higher voltages like the older 660V (now 690V) systems are in industrial use only.

Great video! It’s not messing up. It’s Continuing your education👍

[@ReliableHVACR]

Thank you, we learn everyday 🙌🏽

[@diyhvacguy]

I have the fieldpiece G5. I need this recovery machine!!! Amazingly simple and easy

[@bryanswanson5007]

I have the vp87 and youre not supposed to store with oil in pump. Says it in the manual, reason is because the oil resevoir is always open to atmosphere so your oil will absorb moisture and your following pulldowns will suffer because of it. Just drain each time even if you plan to use the oil more than once.

[@neok1996]

I noticed that the internal piece of the fitting never could have fallen out and yea I know it's easy to say after

[@georgebrabec1749]

Don't know how old this one is, as I just found it, but my advice to you is stop beating yourself up. I have been doing heavy commercial all my life. I can tell you about some major mistakes. As long as nobody gets hurt, you are good !

[@Syphonfllter]

"I'm not doing all that again." I hear that, but sometimes you don't got a choice man. Happened to me last week replacing a oroa valve, no leaks then liquid pushed a pinhole leak through the receiver side, probably nitro pressure building while brazing. Shit sucks, but it is what it is.

[@HVACR559]

Always have to cap a cormax fitting when recovering or pulling a vacuum or the large piston like valve acts like a check valve. Fortunately I learned this lesson while recovering from a condemned unit.

[@MariosACandRefrigeration]

You can put a tap valve on the LPS its like 5/16 line.

[@ReliableHVACR]

I never would have thought of that, thanks 🤙🏽

[@matthewclemons1574]

There’s a tool for the core max for quick removal. It’s pricey but a life saver

[@jesseh5554]

In a pinch like that you can use your recovery machine and push the refrigerant in the liquid line. Obviously do with the unit off. On bigger RTUs and such that's usually how I charge the whole thing.

[@ReliableHVACR]

I think I've heard of that. Haven't tried it but thanks for the tip

[@Georges3DPrinters]

21:02 so what happened to the backside of the coremax? That didn't look like it would fit and that sound when you turn on the vacuum pump 🤔 I'm still wondering where that part went......

[@Georges3DPrinters]

26:00 OK makes sense now. I had seen it, and was thinking about it.

[@nicholasmendoza6159]

Start pumping with old oil then deep pull with fresh. Save time and money. Also gets fresh oil for the important part.

[@gnasty30]

Your good dude! We have all been there and done that so no one should be giving you shit. You don’t know what you don’t know till you come across it but what separates you from others is that you own up to your mistakes and learn from it. It’s a no harm no foul situation

[@rafaelgomez4304]

Keep swivel tees in your truck to use when coremax starts leaking

[@ReliableHVACR]

Yeah when they leak. The pin broke so I wouldn't get pressure if I used one here.

[@rafaelgomez4304]

@@ReliableHVACR I thought the whole pin came out. You wouldn't get pressure after?

[@ReliableHVACR]

@@rafaelgomez4304 the back piece with the gasket stayed stuck in there and closed it off. I wish I could have slapped on a swivel

[@ares3914]

Always get rid of those core max and add service ports. They suck.

[@andygalindo8978]

You should see the crap I do. And I’m not tired. I just suck.

[@ReliableHVACR]

😂 na man we all go thru it

[@vnesmuonnam]

Thank you for showing the mistake. You save a lot of future mistakes

[@HVACGUY]

Great video man. I learned a little something in this one.

[@R2D2471]

Ain’t no shame in your game brotha much love and appreciate you sharing your experience.

[@ReliableHVACR]

Much appreciated

[@dwntwn3479]

You made the right decision not to recover again because you were tired and your focus would have been off. Choices like that is what makes great techs!!!

[@ReliableHVACR]

Not a lot of people think about that, tired or burnt out techs make big mistakes even if they are really good techs.

[@Freezier134a]

Core max is crap. I remove that crap and braze it over, braze in regular Schraders, way more future proof.

[@ReliableHVACR]

I regret not taking it out now

[@jonnymac31]

A 3/8 process stub fits perfectly when you unbraze the core max body.

[@jasonjohnsonHVAC]

You are a good man Adrian....we all make mistakes...part of being humans.....what sets people apart is owning up to it, learning from it and trying to always improve ourselves.

[@ReliableHVACR]

Yes sir, thank you 🙏🏽

[@anthonywoolf9087]

Keep them coming man your good. Thanks for posting

[@flexortiz92]

Good shit bro life of an hvac man

[@anwarattiek673]

Yoo I had recently just seen a core max and i was flabbergasted! Great video brother🙌🏽

[@FMJR8891]

I wish I was smart to do this I’m not good at skilled work

[@muniznick]

Harlingen? Wondering if a reg Schrader valve with a male threaded end on opposite side would fit, cheaper and easier repair in future when you remove coremax fitting like you did, Coremax tool too expensive $400+ on low end.

[@ReliableHVACR]

Mcallen but we service the whole valley. I know every tool is an investment but I can't get myself to buy it 😂 plus it wouldn't have even helped here with the old one breaking off inside

[@swanjaymusic]

Most guys out here would not even admit to a mistake like that, unit works keep it moving...

[@Patech87]

Thanks bro great video me always learn new things every day God Bless

[@brandonbacon5241]

If it was easy everyone would be doing it. We’re only human -Chris

[@OleRazzleDazzler]

They make coremax tools to replace under charge

[@Brisket9392]

It's wild that you consider this RTU "old". Nothing running 410 is old. Not uncommon to see units from the 80's and 90's around me. Heavy stamped plates. I would never consider replacement on that unit especially with working compressors. Why not throw a bead on the leak on the evaporator while you have the gas out?

[@ReliableHVACR]

They buy their own equipment, it's up to them. I always give quotes for proper repairs but once it adds up they just go and buy a new one instead. Condenser was getting brittle, only good thing is the compressor but for how long.

[@thesilentonevictor]

Mistakes makes you improve its one step at a time

[@desieranks]

Why didn't you replace the drier?

[@ReliableHVACR]

That was my call not to. But you should. I didn't need nitro and torches for the repair so I didn't do it. It's an old unit they probably want to replace instead of more money going into it. The bill was already sky high.

[@c21meister]

Where can you find the core max tool?

[@ReliableHVACR]

It's by JB you can find it at a supply house or even amazon

[@winkhvac62]

Good one

What is your hourly rate for commercial AC?

[@chrismitchell3005]

A very stupid question ? We is the purpose of the CoreMax to begin with?

[@ReliableHVACR]

Not at all. It's a high flow port, just less of a restriction vs a normal shrader. But just a pain to be honest
