So my comment is totally unrelated to this specific video but it does relate to all of your videos. I just want to say thank you for doing what you do! I just completed my 609 certification for heavy duty diesel. I know now that what you do as a job is a totally different certification but everything is mostly the same. I’m starting my third week of AC systems and your videos have helped me almost every time weather it be how a txv works to how to apply the bubble solution the best way. You have helped me a lot!
Just as he says it’s rare for the rails to leak up here it goes off. It’s just gonna be one of those days. Great work and thanks for the awesome content stay safe and take care
. . Respect to all of your accurate diagnosis spelled out for all to see here on these videos , question . . what's your go to method of recording what you are showing us , cause it works . . bravo
Really good video, as always. The Explanation of flooded charge, receiver level and the stuff that goes along with that is quite interesting and easy to understand. The HVAC stuff I deal with, is the automotive stuff. Worlds apart yet similar in some ways. Keep up the great work Chris.
Is there a reason why all these HVACR-Parts are not made of stainless steel? I think this would prevent leaking and would save costs in the long run. Bonus: The RTU would't look like a rusty mess if it sat for several years in the rain. In industrial kitchens there is everything made of stainless steel - so the refrigerant lines and condensers wouldn't be that more expensive in the big picture.
That was the date when it was last charged and marked at the 3/4 liquid level. The receiver was original from 2004 when the rack was installed hence why I had to cut it off and use a bracket to replace it
With the leaking pan chiller, I would cut it out of the system and pressurize it independently, depending on what they use to blow the foam inside the walls it can set off your leak detector, you have significantly more experience than I, but just a thought
The cold rail guy--can he repair duke/subway style ones. I’m in a pretty small market and would really like to be able to make a repair now and then here....Florida.Thank you.
i love it when he calls the blowtorch a heatproducing device. a normal other torch that is called a blowtorch is gonne be is like "did you just assume my gender"
Just a bit curious what the rules and regs are for topping up a system in the US with a known leak in the system. I’m in Australia and by law we aren’t allowed to do it, $250’000 fine or 2 years Jail and loss of licence. So much easier to top off a system to see if it’s working correctly before recovering the gas
Same in the UK and Europe and any other country who signed the Kyoto protocol. The US did initially sign it, then withdrew. I worked with an Indian guy who would blow refridgerant off to atmosphere. When challenged he simply replied, "this is what we do in India".

I kind of want to meet the guy who thought it would be useful to have the leak detector relentlessly beep while you are trying to work. What is it a life and death situation where you need positive feedback every second ? The blinking LEDs not enough of a hint that its working and detected NOTHING ? Feels so great to walk around a building with this obnoxious wand in your hand and if you shut it off for a second it punishes you with maximum beeping during warmup. Screw that guy.
Hey Chris how are you? Just to clarify, when checking the winter charge, you have the system pumped down right? Also I notice that you are very deliberate about saying “heat producing device”, I am assuming your not saying oxy kit for legal reasons or do you actually use a heat gun or something else? Love your content man, thank you 👍🏼
YEs the system is pumped down when check the receiver level, I will discuss this on I’m going live on UA-cam this evening 12/7/20 @ 5:PM (pacific time) to talk about my videos and answer questions from comments, emails and the live-chat, Come check it out ua-cam.com/video/5vc9-ygyL0o/v-deo.html
I have trouble completely understanding why you need to change the charge from winter/summer. Does the ambient temp really change that much? There is a 15deg swing between winter/summer where I live so it's unconscionable to me. Would a bigger receiver solve the problem? If I head out west far enough it gets a lot colder, some of the heating units (reverse cycle hvac) I need to put defrost mode on the outdoor condenser unit because it ices over, but still the units operate within range. Maybe I'm fat because refrigeration is so easy in my area lol
I have never had that issue in Michigan. We get into to high 90's and 10 to - 15 below in the winter. This checking the charge in California when its 100 then cold for them at 50 degrees baffles me
@Timothy Salomon are you saying, he is charging to best ability at one time of year, then adjusting charge at a better time of year, and then not changing the charge after it has been charged at the best time of year? Or that the system has been designed to require 2 different charges and must always be changed for correct operation? If so, would the unit fail if not done or just put more pressure on the tx or condenser ect..
Does anyone know what effective cooling and a effective heating means as in setpoints? I have a occ and unocc setpoint for heat and cool, but not sure what the effective means.
Typically found on liquid line. Just a method of checking whether a system is in a fault condition as the sight glass should look empty when it has 100% liquid. If it’s a saturated mix it will “flash” and that tells you there may be a fault in the system 👍🏻 very basic explanation but hope it helps

Correct me if I'm wrong but the only difference between the old refrigerants and the new supposedly atmospheric safe refrigerants is removal of chlorine from the mixture. Most of the new refrigerants are still hydrofluorocarbons where as the old systems used hydrochlorofluorocarbons. Chlorine and fluorine are both halogens and I know that fluorine and fluorides are toxic to humans so I'm surprised that we still use hydrofluorocarbons.
Yeah with the Chain restaurants they all look the same in the case of this video 4 of the locations I service look identical I will discuss this on I’m going live on UA-cam this evening 12/7/20 @ 5:PM (pacific time) to talk about my videos and answer questions from comments, emails and the live-chat, Come check it out ua-cam.com/video/5vc9-ygyL0o/v-deo.html
You have the best HVACR channel.
Thanks bud
_very rare that they leak up here_ ...... *BEEEEEEEEEEEEEEEEEEEEEEP*

@7:42 That receiver is OLD. June 2019 and the coating was off it already.
That was the date when it was last charged and marked at the 3/4 liquid level. The receiver was original from 2004 when the rack was installed hence why I had to cut it off and use a bracket to replace it
Another top job and video Chris? Loving your channel
The copper is just to keep the coating in place. Thats wat keeps the refrigerant in the system these days😪 btw 13:06😆
Great job and video like always

Chris is the man !
Reminds me of the old song by Mötley Crüe - Same Old Situation. Good Video!
Man at first I read that thumbnail as "THE COKE LINE IS TOO WARM".
I swear I've never done drugs.

I don't "do" cocaine, I just like the smell.
The cold rail guy--can he repair duke/subway style ones. I’m in a pretty small market and would really like to be able to make a repair now and then here....Florida.Thank you.
I wonder who that Specialist is and what he does to fix and restore the cold rail.
I bet he owns at least 3 hammers
you tried Action clear? it's a conformal coating that's supposed to protect against corrosion. might be interesting to try on problem areas
Nice video
I like the sound of the h10 from backnarack
i love it when he calls the blowtorch a heatproducing device. a normal other torch that is called a blowtorch is gonne be is like "did you just assume my gender"
Every time he says it I need to take a drink (cause you know hes gonna say heat producing device)
maybe someone complained after blowing that plug by holding their torch to the receiver for too long ....
i assume it has something to do with the ultra litigious society of america
If you need help on those pan chiller to replace it we can make a new one and install it. Nice videos i like your channel

In southern California it easily gets freezing in the winter and 100+ in the summer with little to no transition time. Its 80 one day and 40 the next.

is it maybe something to do with the building being artificially heated on a day when it's cold outside?
@@cliveramsbotty6077 No! The inside has nothing to do with what's on the roof.

no

If heights weren't a factor/requirement, I'd loveeeee this job
@Timothy Salomon is there a way to restrict myself to that? As far as I knew if I worked for a company they'd force me to do whatever is needed :(
Question . Have you ever had or seen a compressor explode from over charged ?
A guy I worked with was leak checking a unit and he put to much nitrogen in the system and it blew the suction line out of the compressor

I want to know how they get that kairak pan chiller apart. We condemned them with a pan chiller leak.
Yeh I’d love to see their “specialist” fix those cold rails!!! Just seems like it would be a nightmare.
3:20 Coil is sus
didn't look like it was a joit that was leaking, looked like the copper became porous. how does that happen?
Absolute dickload of corrosion.
formicary corrosion caused by chemical vapors from cleaning agents, also from acid fumes from foods
@@rustblade5021 ahh, from the outside. didn't think about that.

Good video . Where do you get those receiver brackets ?
I just had my stainless steel shop make them for me
@@HVACRVIDEOS cool , thanks for the info
the real question is, would you order from this restaurant?
How do that many leaks form... wow! also great vid
Who's idea was it to have components bolted to the base which is inaccessible?!
it sells new ones pretty good
your leak detector is blinking ...so you must charge it or it brings false alarms
Would a Mapp torch work for heating the receiver?
mapp torch would also work amasing for finding leaks in R290 system. Im no hvac tech, but reading between the lines, yes, just dont melt the soft metal burst valve thingy. and obv not on a leaky R290 system.
Yes
I hate this kind of equipment. It is very difficult to fixed .
