- So they were a bit frantic when they called because the health dept. found the walk in cooler was too warm, however it didn't all of the sudden start temping high. This had been a problem for at least a few days.....

Thanks for showing that sightglass picture...I always wondered what you were looking for!
That was an excellent demonstration.
if you see any bubbles, there's likely big troubles. lol.
of course you have you account for ambient and box temps, run times and a dozen other variables. but in general, the sight glass should be bubble free most always.
The video of the bubble whisping away made me feel tingly inside. It's a good feeling. Hard to explain.
i never fully understood what it meant for the sightglass is clear. now i know
Hi I am 62 retired HVACR Service tech. Gotta say how much of a awesome job you do showing your work to help the younger techs. I can see how much you care about your customers, and the job you do for them. Thank you.
When your screwdriver fell out of your hand I started swearing instead of you! Awesome work, just awesome.
Speaking of subscribers, a lot of RUclips channels have said that they have found that many subscribers have been un-subscribed by RUclips themselves without knowing.
"The Walk-in is too warm and the health inspector is here."
Ah yes, the old "it wasn't broken until someone important looked at it" excuse. I'm fairly certain you could hear me rolling my eyes all the way in Cali!
You’re the best HVACR RUclipsr I watch, I’m only 7 months in this trade with no prior experience and your videos make me feel like I’m at work learning something new on every video. I love how in depth you are with explaining. Thank you!!
Greetings from Canada, I’m 18 and have about 2 months until I finish trade school, your channel inspired me to pursue this trade 🤘
it still amazes me that R22 is still being used and repaired. in the EU finding R22 in a system is basically an instant death for the install. legally the only thing you can do as a tech is recover it and remove the system or convert it to 407. but in reality most owners the we tell that it has R22 basically only care about how fast we can get rid of it and replace it. not in the least because of the efficiency. these old systems are just comically inefficeint to modern installs where everything has a VFD. i cant even think about how much virgin R22 has to go for these days. i know a few coworkers still have a tank of it stored in the back of their garages.
It was $1600 us dollars for 30lbs jug in the midwest this summer
Don't know why youtubes player hating, these videos are gold! The big picture mindset is a game changer, call backs have dramatically decreased for myself because ive stopped solving symptoms and started solving problems
Honestly I was stopped watching RUclips in general because of how busy life gets in the last few months, but now that I have some spare time I can get back to watching my favourite channels (including your's)!
“Southern California is so bipolar in its weather”
I respect the hell out of you, you do an AMAZING job troubleshooting and fixing the whole problem, but 80 to 55 is NOTHING for the Midwest, happens a couple times a month in the summer here, and a couple winters ago we had 70 degrees and sunny one day in mid January and the next was below zero. 60 to snowstorm is a once or twice per winter event here.
Dude love your videos just started in commercial HVAC working with restaurant's. I learned getting out of tech school I didn't know much but your videos have showed me real world stuff that I'm running into.
how are the conditions in the restaurants you work in? i do a lot in new orleans and it is so god awful. Super successful restaraunts with A's from health inspectors but if i showed pictures of the conditions no one would ever eat there. almost every place is so disgusting and chaotic and extremely small/tight which makes it incredibly difficult to diagnose most pieces of equiptment. Looking to move somewhere else in the future just wondering if this problem will continue everywhere I go.
Come on yall 200K by summer. He deserves it.
That would be really cool
For sure, this guy is awesome
You must have started learning this trade when u were 7 or 8 yrs old!! Your knowledge and integrity are second to no one. Fantastic channel!
Your about right I started working with my dad about 7 years old... of course at that young age I was just observing but as the years went on I learned more and more
@@HVACRVIDEOS I always look forward to your next video! Love watching a master at work!
its worth noting that the headmaster valve is an OROA valve -- as in Open On Rise of Ambient -- that small cap tube on the head opens and closes on outdoor ambient temp -- it doesn't meter like a CPR valve that operates on system pressure -- as for fan switches - they are great to use on systems where wind isn't a factor, wouldn't try it on a rooftop like this one. Thanks for the content and the tip about the service valve is GOLD -- almost 20 years in this work and I STILL mix that up from time to time like a idiot
When you roll the dice on upgrading a system and come up snake eyes. Gotta love it!
Chris with your professionalism your work will never stop hope enjoy getting busy an bussier my fridgy.All the best
Pretty impressive seeing equipment from the 1990s still kicking! And still looks clean. Love those old Master-Bilt condensing units. So heavy duty, even the panels look heavy and built to last. Great video and thanks for sharing !
Expertly fixed, nice job. By the way, those sight glass shots were really cool, watching it fill up!
"I'm not a huge fan of fan cycle switches" this man definitely doesn't deal with snow lmao!
Really great job as always. These videos are always so invaluable. The more I learn, the more I strive to be as thorough and thoughtful as you! Really great customer service here. On another note, that compressor was from 1996!? Holy cow, what a work horse!
Pressure control 80's montage was unexpected but welcome!
Can’t believe you’re still filling R22
From my observation, the algo started pumping your most recently viewed channels over things you've subscribed to even if not subscribed. For channels I don't have notifications turned on for, it is pushing that content below newer content even if I'd prefer to see content from my subs. Likes probably help too. That's said, liked, sub'd, and notifications on!
I’ve only seen the dual pressure ports on the suction service valve and they both work the same not like this one where pressure is always present on one of the ports. That’s why I like this work, it keeps you on your toes.
In my experience the one furthest from the valve always has pressure specifically for the pressure switch to be uninterrupted by the use of the normal valve port!
@@mynamesdan2164 I appreciate the good information. 👍
Thanks for the in depth video! Really enjoyed the content, always nice to see the big picture.
Great videos great info very thorough I’m grateful
Nice job again.
I would recommend cleaning up the oil that leaked out of the schräder at the evaporator. Oil is the first “ leak indication”. If you do not clean it, you won’t know if there is a new leak. Greeting from the Netherlands, keep up the nice video’s your making.💪🏻
Don’t see many refrigeration techs using that leak detector. Very interesting, thanks for sharing
I believe the issue with viewer retention has a lot to do with people becoming bored with the content. There was an influx of viewers when the RUclips algorithm decided to advertise HVACR videos in people's recommended feed. It was something new, fresh, and exciting for a lot of us. Unfortunately, these types of videos all start blending together once you've seen someone work on an freezer, cooling table, ice machine, a/c, etc. once or twice. I'm not sure how you'd keep things fresh and exciting for the viewers, but it's hard to keep producing the same material and expect more viewers. Another thing in play is that when these HVACR videos became popular, the additional viewers convinced a lot more HVACR guys started producing videos--diluting your viewer pool and making subscribers get tired of the content faster since they're watching more of it. Sucks, but I've experienced this before working as a social media marketer before switching to software engineering.
You make some very valid points!!!
Yeah, take us onto some of the bigger jobs
Said it perfectly. Your video's where the first who where recommended to me about HVACR and i just stuck with you because of how you explain things.
Seen plenty of other HVACR but just dropped them all because of over-saturation. I think you where recommended because i was searching Manitowoc icemachine manuals.
Side note; i am subscribed, and youtube never unsubscribed me from anything. I do however never put notifications on because they annoy me and i just live in /feed/subscriptions/
@@Eledore I do pretty much the same. I have changed from watching many to watch those that seem to have an interesting subject that I haven't seen before. I don't work with HVAC, I just collect some knowledge here and there since it might be handy in case I encounter a minor problem so I can understand if there's a workaround or simple fix or if that problem requires advanced knowledge and equipment.
Simple fix - see that the evaporator is totally solid with ice and don't cool - just try to de-ice it and then see if that helps. If it ices solid in a day the problem is bigger and just call for help.
@@HVACRVIDEOS Hey Chris, can I bring my lab top computer along? it going to be a real mother fooker. just system check?
Great info. as usual thank you Chris.
Great workmanship thanks again for teaching us how to be better technicians and how to check through the system to get things back on track.
Notifications checked and still on !
You are right about fan cycle switches. The old timers swear by fan cycle switches. Headmaster is much smoother and just works better for refrigeration units in most applications. Headmasters are easier to charge too. Just my opinion.
Heating up the reciever to check the charge is one of the best things ive learned in refrigeration.
Most techs would have gassed and go on this one. And they only would have put just enough to fill the sight glass. Id like to work with people like you! No one around here is like you.
Thanks for the nice words bud, I try!!
Good little vid Chris , thx for posting ...
Great video. Thank you. I loved the thermal imaging camera for checking the head pressure control valve. Very true about not stopping just at the first leak found.
Great Video. Thank you for sharing
Thanks for the heads up... I didn't have 'All' notifications turned on. They are now
Thank you for these videos.
Great shot of the thermal cam and all too brief explanation of the cool ambient bypass valve. Had me replaying my Christmas day errors overfilling a WI freezer on below normal ambient and raining, while flipping a piece of cardboard over a part of the condenser coils to raise pressure. Missed seeing you at Kalo's, enjoy AHR expo and await your own home project equipment choice. Be well amigo.
Great tips thnx Chris
I love the content, one reason for less views may be that it seems lately there has been less videos posted. Back 5-6 months ago, could have 8-10 videos a month, now maybe 4, people start loosing track or interest if there is only one upload per week and they look for new content and channels.
1st. Greets from Germany
Und wir dürfen bald nichtmal mehr 404a benutzen. Aber feiere den Kanal sehr
@@niklaspaschen5106 Bei den Amis ist halt alles ein bisschen lockere, ne ?
@@electroimpex8897 Ja ist ja nicht nur Amerika. Die Ganze Asiatische Fraktion ist mit ihrem R11/R12 auch noch da und das Größere Problem. Aber sehr geil wie er alles Erklärt usw. Perfekt für Azubis, hätte ich den Kanal mal früher gefunden
great video!
Try 55 degrees to 4 degrees keep the good tho brither god bless you love your work and craft
Thanks Chris
Approciate. Always. For the. Great videos
Nice work Chris.
It seems this field piece does a good job so far
Another excellent video!
Top job!
I would have loved to have had a mentor like you around to work for in Delaware.
Good job Chris.
Second. I cant sleep and get a treat to a 4 minute upload
Hey Chris, I like your podcast/social media, looking thru some comments/reply? By the way, happy ground hog day. Be you blue or white collar, I can not see your 5 o clock shadow today. I live and work here in Washington, D.C. and you might want to stop at the subway sandwich shop and use their wi-fi again. nanoo, nanoo.
At this point if somebody calls me with our 22 if there is a major problem compressor etc. I just called them to convert the evaporator and replace the condenser. They insist I have them by the entire bottle of our 22. I don’t even wanna deal with it anymore
Why not use a drop in like 438a?
@@benschroeder382 438a or 407c which is a little cheaper and has a better reputation from what I've heard. Hearsay though.
I like that you use that husky 6 in 1. I've been buying them from home depot for probably 10 years now.
Same here I keep two or three on the van at all times
I'm already subscribed. I added notification. A problem is that I usually watch on my television via the ROKU and leaving likes and comments is very difficult.
Greets from the Netherlands
21:27 Yeah, that can totally blow the fuse for some ppl. You sould have seen the head of the "screwing technique" (bad google translate) guy when he heard i used grease on the screws of the engine of my bike claiming it could come loose. Yeah sure, try loosening them after a few months (steel screws in aluminum block, those things aint coming loose to put it mildly).
I like watching your videos. it feels like were job showdoing
Greetings from Romania👌👍
I agree I'm not a big fan of fan cycle switches either but I do stock 1 on my van because some MFGs like them mostly on ice machine remote condensers but also I occasionally run into cobbled together systems made with an off the shelf condensing unit (intended for indoor use) with no head pressure control of any kind and a fan cycle with a swivel T is the most realistic option to field fit the system to work for the customer.
Isn't it always satisfying clearing the sight glass..lol
Watched every call video.
Will try to check out other content too then 👀
"health inspector is here too", ""I hear that as"" the box has been warm and spoiling food for months, but we got a tip the inspector is coming today, so we have to get it repaired immediately!
then they try the "well it just broke earlier today and being repaired now" at the inspector, which will temperature probe to middle of larger foods and know it's been too warm for many hours.
coughs, cough. 🙃
For the low pressure cut in setting: If you have 35 F ambient, your may have a 35 F condenser, means 62 psig on gauge for R22 system. If your cut in higher than 62 psig, like 65 psig, the high side pressure is not enough to turn back on the compressor, this is my understanding.
You are on the right track. Basically you want to keep the low pressure cut in psi lower than the lowest expected ambient for the refrigerant in the system. R22 @ 0F = 24psi. So you would need 20psi cut in for a 0F minimum ambient. R404A @ 0F = 33psi so a 25psi cut in would work assuming 0F is minimum expected temperature.
Another great video Chris, have you ever tried Gomax type hoses for your pressure lines? I’ve avoided copper capillary lines due to vibrations and rub throughs that I’ve seen.
👍💪🇺🇸❄️ Nice work
If you use a celenoid magnet you can turn the system off,dont like to do a leak check on evaps when the system is running
just had a call like this same exact thing r22 and all evaps are totally shot needs replacement bad
Serious question. We have a freezer that’s the size of a standard fridge. At some time the door was left cracked open. I found it last night and ice was formed solid from the back and even bridged the gap the cracked open door left. Where in the hell did the moisture come from to form that solid block of ice? I’m guessing the 8” of rain we had that week here in So Cal helped with the high humidity.
Theres always humidity in the air
From the air. You need to turn the stat down and let it thaw out if it's a solid block. The defrost won't get that. I've put a heat gun in reach ins and just run the evap fans to quick thaw.
@@Brisket9392 it’s old enough it doesn’t have a defrost mode. Yes, I want to trash it but my wife won’t. It’s in my back garage so I dollied it out the door and it took 24 hours outside with the door open to fully defrost and this is in so cal where it’s not in the 40’s.
R22, the lord's refrigerant
I love the stratus 1150 cad
In Australia we can't recharge an r22 refrigeration system, we have to retro charge. Also not sure what r22 costs in the US but in Australia it's very expensive..
I just realised I've been mistakenly calling Nylog "Nyloc" for YEARS. For a moment I thought you had some off-brand stuff.
Try Danfoss Saginomiya fan speed controller, for condensing. Work like a charm, in winther situations and low charge.
And that high pressure valve, that's sweet..
is there any way to change a pressure control like that without introducing air into the system aside from pumping it down and pulling a vacuum?
I had a walk-in today and customer said door falling off tracks as it is a sliding door. They bent the aluminium door track from throwing the door shut and jumping when it hit the door stop.... Then they said oh it not coming down to temp..... Spent ages finding the leak and ended up reclaiming the gas and leaving trace gas in the system. Pumped it up to 250 psi and found the leak on txvalve suction flare. Cut flare off and didn't have enough 1/2 to flare it again so had to braze a new pipe in. That was a slow leak so hadn't been performing for a while. That pushed all my jobs for the day as the office thought it was just a simple door repair.. 😞
Are there any fan speed control systems instead of on-off fan cycle switch?
What kind of Thermal imaging tool do you use?
Do you get a lot of use from the FLIR. New to the field and I've seen others using them. Was curious what your thoughts on them were for diagnostics and where it's good for.
7:35 for the moneyshot
Awesome Video as always! May i ask you which type of watch youre wearing?
Samsung galaxy watch 4 with a sup case band
Thumbs up
Who does that suction line service valve have a port that is always open?
did anyone notice the typo in the thumbnail
Remember kids: work smarter not harder
Great tech. Whatcha think about zoom spout oil on flares ?
It's fine. Used it for the first part of my career, just make sure you don't get any in the system... if nylog gets in its not a big deal
Isn't there a inviornment friendly substitute for R22?
The air in the capillary tubes on the pressure control shouldn’t be to bad, since the system pressure should trap it in the control.
At lest if I understand it correctly.
As far as I understand from a chemical and physics perspective, all gasses and chemicals will diffuse into equilibrium with what's around it. A few random molecules here and there will swap places where the two substances meet. So, I'd say over time the air and refrigerant would slowly mix until there's a equal ratio of air and refrigerant in the entire system. But, it WOULD likely be trapped by the pressure initially, so you'd never get the whole blob of air introduced into the system at once. And given the volume of such a small tube.... my guess is it's negligible what performance impact it would have anyway.
@@theLuigiFan0007Productions But will they diffuse when the other gas (the refrigerant in that case) has a way higher pressure?
I agree about the mixing in the same pressure, but since especially the discharge one is way higher I‘m not so sure.
Either way, we only talk about a very small amount, I don’t think the system will ever realize it’s there 😉
Do they make variable speed fans to be a softer gentler version of a fan cycle switch? (Vfd or ecm or any other tech). I know variable speeds fans exist generally the question is if people make ones and the controls specifically for that purpose.
Yes they do but the reliability and cost are not great
I’ve put bluon instead in the system, is that fine?
Definitely don’t see a lot of those pontoon boat condensing units anymore
I kinda miss them, lots of room to work
I was wondering, why couldn’t you change the refrigerant to R-422b?
Which thermal imaging camera are you using? Looks like an extremely useful tool
It's the hikmicro m60
As someone in the residential side of the industry, I have to choose what points I want to make to be as effective and efficient as possible when bringing up preventative maintenance for a customer. I have to explain it thoroughly enough for the customer to be well-informed, but quick enough for it to not be class on their entire AC System.
If you want to increase viewer retention, try out a trial period where instead of posting the raw videos you take with your real-time voice over, you take videos with no voice talking to the camera and instead do a voiceover at home with your hindsight in mind. When you know everything in the end and you have the time to just re-record a voice snippet, you can probably cut these 45 minute long videos into something as short as 17 minutes, and these 30 minute long videos down to something as short as 12 minutes.
I also think that shorts might be a fun little test. Trying to condense a 3-hour call into a 1-minute story with the problems, the buildup, the issues, and the solution fit into one.
I like his system the way it is, I like this mixture of talking live and talking back at the shop
Hi I'm form India I have been watching your video very long time. I'm an digital marketer i just watch your video for educational and i great i learnt many things it not my field of my work I just have watched one of your video since then I have subscribed to your channel is great and educational will keep supporting
Love form India ⚡
Thank you very much!!
Shout out to my cousin, Joe, who is in HVAC.
Hello Chris, which thermal imaging camera are you using?
great video again :) Greetings from Austria
Hikmicro r60
Yep
Since you are gunna have to trash that system soon can you put food coloring in it and test if the filter can remove ot
