THE BEER WALK IN IS TOO WARM 

They put fire sprinklers is crazy places, LOL 😂

warm beer, *panic panic, come fix it now!* warm/thawing food wait multiple days then call for service. 🤣

20:37 Nothing worse than a sensitive knob 😂🤣😂

How do you use your fancy hook when you need to bring a nitrogen bottle on the roof? I have some guesses, but would be interested to see. I wish the small bottles had a cap for the valve stem like they do on the bigger bottles, then you could make a custom cap that has a ring on it to easily grab with the hook.

I autopsied my first compressor today, a Copeland Scroll. Originally wasn't going to since I new it was falsely condemned, but now I know what a compressor is supposed to look like inside. Bright yellow oil, nothing but shiny grey metal, and super smooth movement. Oil was a bit low though. Now when I autopsy a compressor that is actually bad, the damage will really stick out!

Hmm, in CT we have 25lb bottles, we don't call them 30lb bottles and they all say 25lb net weight

It’s really important that not only you elbow says click when torquing with wrenches, you also need say “click” out loud, preferably right after you removed the wrench from the nut.

The torch has a packing you can snug up to help alleviate some play.

Dude you have no idea how much your videos help newer techs like myself. Went from strictly chillers to work on everything alot of VRF and multi head mini splits and infinity and refrigeration. Watching your diagnostic steps helps me so much I've gotten ten times better and a 8 dollar raise. What you are doing is helping so much bro

My first job in high school was a tech at a refrigeration test lab. One day I was told to tighten up 24 fittings on a residential test setup for 12 units. Being the strong ambitious high schooler I was, I torqued the heck out of those poor swage fittings... Ripped every one apart for a 100% replacement rate. My senior tech (an ex Lennox guy in Columbus) was pissed.

80% of capacity in cylinder due to blends and room for expansion. It’s not like the good ole days

Thank you for that sight glass closeup when it cleared up.

No wonder you got outsmarted by the wrenches, you forgot to yell "Click!" when the flares were tight enough!

15:00 I have come back to locations 10 years later and found tools I left behind up in the roof before. Almost immediately when poking my head up there I see it and it triggers the memory of when I lost it. I imagine you have a few "missing" tools at previous jobs just waiting to be found again.

Half gallon products that are now 50oz are the rip off, social media dude just doesn't understand gross vs net weight (not getting into gas expansion, etc). Next time just tell them I have neither the time nor the crayons for this conversation 😄

HVAC tech here , New to ref and big fan of your vids. I got two questions for you; 1- you said turning off power keeps the freeon in the evap but I thought if u de energize the solenoid it shuts blocking the freeon from entering the evap? 2- when you pumped down I noticed you didn’t front seat the suction valve once you shut off, does that not apply in ref? Usually I close my suction once im at 0psi on low Thanks in advance

Love the videos, completed my Fgas about 2 years ago and im learning more everyday thanks to them! FYI I’m always mentioning this channel for all the guys I know who are in hvac in the UK. Keep em coming!

What is the middle part in the sight glass for?

The service valve on the suction as side is a cost, but the time gained by having a blow through during assembly is worth the service valve.

🙌🤘Did someone mention overtime 😮. I wonder who that person was thought thought we were getting ripped off🤔

I wouldn't have done shit for him or anything that was anywhere close to him having a part in it. I would say you pay me for everything you owe c me from when you filed bankruptcy and the job I'm doing up front. If you can't pay for it all call someone else to fix it.

One good reason for the second service valve is to isolate the drier/sight glass for quick and easy change out on moist systems. It just saves the step of pumping it down.

HA! I use that fire sprinkler as a prime example of situational awareness with my students chris! Warn them about catching that on their tool bag!

1:05 is that your lunch heating on the roof? It looks like a Subway sandwich LOL!!

Where is summer at bro? 82 degrees in June, ridiculous.

Unfortunately, I use the same free-spinning nut on copper water pipes of 1/2. I've come to find that all free-spinning nuts leak at the stem despite me, using a parer or rubber mating between the parts. So the best technique I use is to use some plumbing hemp at the threads and pack everything including the stem, in thread sealant. Then screw everything sufficiently. That works like a clock. I've come to know that the correct force is when you wait 5 minutes, apply kitchen paper to the stem, and not see any condensation from the water. So the industries are not so dissimilar.

Great Video. Great Job. Nice Work . I'm learning Refrigeration . Thank you for making these video. Thank you for sharing

If im uncertain about sightglass either full or empty, i always pump it down lf it has a tank. That way you can tell!

Thank you for mentioning to add extra solder on the pipe junctions me personally like to add extra solder too and I thought I was doing it wrong but now you confirmed it to me that I’m ok the way i been doing it, too me it just adds a little extra protection anyways thank you for being a great teacher for those of us that are barely starting on these field work I have learned a lot watching your videos thanks again

You are an amazing tech. You are actually pretty damn top notch. There are always asshole wanna be super techs who criticize no matter how well you do. It really does trip me out how arrogant some people are. I give you major props, this trade ain’t easy, it’s hard as hell, especially when it’s 110 degrees out. I am amazed that you have the patience and diligence to film this and explain while you are working, incredible, I definitely don’t have the patience. The fact that you cut open your compressors just to truly know what caused the failure is just above average. Many of us just don’t have the passion to do that, and honestly I feel guilty not having done that more myself. It truly does make you have such a more in depth knowledge about compressor failure and what caused it and what it actually looks like mechanically. My hats off to you sir, you are truly a professional. Keep up the good work, I pick up new and better methods every time I watch your channel. You are a credit to our industry sir.

Yo man you are an inspiration for real!! I've been in the trade for 12 years and I love it, wish the guys I worked with would enjoy it as much as you seem to enjoy it.

You keep doing you. Cheers and Thanks for the videos

Johnstone carries those spark igniters that Chris uses for his torches in case anyone needs one.

Hey Chris, when are you going to put a beard to your meme? 🤣😂🧔🧔🧔🧔🧔

Lubricating the threads prevents galling of the threads. Of course, you should lube them. Those people running their mouths. Excellent video.

You would be frustrated with the company I used to work for. A lot of the employees are not trained HVAC people and the boss holds all the licenses supposedly to operated. He tells them to vent systems and lets certain favorites to get away with doing real crap work. He canned me after I noticed some real shady stuff happening and have moved to my current job in which I don't drive all over the State of Washington. I now stay on grounds and am chasing the work that the previous company was doing to the equipment and feel that they were not qualified to work on restaurant equipment. They should stay with Air Conditioning from what I have seen. I was going to comment on the connection point of the vacuum pump but had a second thought after realizing how the TXV will work when there is no refrigerant flow. As I always say, keep the equipment going though it may be a turd until it is a burning heap.

Hey why is there that glass thing....should be alot of bubbles right?😊

This dude is has the best refrigeration channel out there. Super humble and knowledgeable .Thanks for sharing this info.

I wonder if there is someone who got a shot of big blue in their bloody mary lol

I “”always “” switch our systems to flare❤ Time is money and allows me more time to check out the system for any future possible problems.. AN??? Lol at my age? I don’t like making a lot of trips up an down bringing stuff to the roof . So I guess in my old age I have gotten lazy too😂😂😂😂

💪🇺🇲❄️👍 great informative video thanks for sharing

You’re Videos are so Good, how could Anyone Not want to Subscribe ? I know Answer is Clear but also know Common Sense is Not too Common, Right ? 😬👍

Good job Chris, I heard the clink in your torque arm wrench, some people are just never happy with how people do things, just unhappy individuals.

You make great vids ❤

That last section before the sit down really felt like you were explaining stuff to one of your apprentices. Fabulous work sir

Chris, if you tighten the packing nut just below the on/off knob then the knob will not be as touchy. About 20:40. I also like to make everything clean and neat. I have some OCD in that respect.

New subscriber here, awesome video and ur great at explaining ur process while repairing. Glad I found this channel.

Take it service work is better pay then install

Whats funny is i know the chain based on the equipment.

i like this style of video

Isnt so nice to have the right tool for the job on hand? I have invested in so many small tools for my business but I NEVER get tired of needing said tool and having it on hand! :)

It’s going to be hell soon with the new refrigerant requirements coming into play soon as it’s flammable. It will make jobs a lot harder like this and how will that work with fire regulations speaking it has pounds of refrigerant.

Ahh...the old school "elbow torque wrench" application. Your dad must have taught you that 😉. Clean in informative video Chris.

Installing the sight glass in the vertical position makes inspection easier

I have done 2 jobs (residential) where the customer complains about a loud noise “condenser is too loud” while running anyone knows what can be the reason?

Huh?? Overtime after 4:00....?? JEEZ, I have started at 6:00 am and worked until after 8:00 pm!! Made lots of good, honest money! We only charged overtime rates on weekends. I actually enjoyed all of it because it was challenging, entertaining, and fun back in the good old days.

11:04 - Wow! Thanks for showing the sight glass being cleared. That was beautiful. Now that I’ve seen first hand (well. . ., you know what I mean) what I’m supposed to be seeing, I can say this is the most helpful segment of this video for me! Thanks for sharing your knowledge and insights. 26:13 - and a little Gump thrown in for good measure. Thanks.

Thanks for another great video, Chris. I really liked all the extra effort you put into it suchas showing how a sight glass clears, how prepare to make prepare a proper brazed joint, what to watch for when swaging or flaring pipework, and loosening valve packing to prolong packing life. You packed a lot of tips, advice and other information into this video.

your other left @ 23:00 lol one thing that always occurs from time to time is backwards wrenching, now throw some left hand threads in the mix for real fun. 🤪

Oh, my. The bad subcontractors are international problem, not he ex-USSR... P.S. next level, after sister's bankruptcy: open a new company on some tramp's (hobo, homeless - pick a wording what you like) documents to avoid any property claims. I dunno, is it prohibited in the USA, but in my country is very popular "business" case. I put it here only to make you aware of that kind of bad business.

Well I don't know every country has a different colour code for the refrigerant well i a. From south African and 404a is in a orange bottle

We DO have to be just like you! Everyone should be a clone! It'll help sell you a lot more hats when we are all sitting at our computers narrating our HVAC videos. :)

I learn a lot from you thank you for making these videos you teach me a lot of things that I didn’t know and I’ll be going into commercial in a year when I get my journeyman’s license I love the videos👍

Btw thanks you helped me with a repeat call multi tech and a comp later condemned the txv. Few hours later txv swapped new filter haven't been back that was a few months ago.

There is a safety technician mandatory here, who is audited about how effective he is by the state. Just tell him about that hazard and make him write it it the state book he has to have. If management doesn't correct it there should be a fine for them.

Thank god for RU-vid. I tell so many guys to watch your videos in their free time if they actually want to be a better technician. Other than that, we need more guys like you in companies teaching us young guys how it’s done. I’ve learned A LOT from you and am extremely thankful for it!

❤❤❤

Before I watch the video, i wanna make a prediction. Issue due to lack of preventative maintenance.

There’s a nut at the base of the knobs on the torch handle that you can tighten up to make them less sensitive to being bumped

40 years in the trade. I like this video!!!

Electric heat because you typically run a beer cave below 34 degrees. Too cold for just an air-over defrost.

Haha that’s the first time I’ve seen you braze without nitro!

Cylinders are filled to 80% capacity. 30lbs X .80 = 24lbs

Sight glass basically just shows if there is any subcooling, correct?

CPS blackmax torque wrench is a solid choice

The condenser is in a excellent place nowhere near a exhausts so Grease shouldn't be that big of a problem.

I couldn't agree more with you. Where possible I use flare fittings as well. Many times I will use leak lock rather than nylog but I have used both. I have an inficon DTEC and a Bacharach h10 leak detectors. And there will be times that I may use UV dye with a blank light. But I do agree with you we all do things differently. And I as well am meticulous for cleaning copper pipes before brazing.

Another brilliant video. Watching from the 🇬🇧. Not been in the industry long. Busy season is just kicking here. Keep the videos coming. 👍👍

Chris, I'm a IT-professional and L-O-V-E your long and explaining videos. In our world, we have also cooling going on, like the datacenters (I know, it's A LOT bigger). I learned a lot from your vids where I can understand the background of the cooling systems in our datacenters. I'm one of your subscribers from the beginning. Just keep going on man, love it! Greetings from The Netherlands.

❤ well?? On a 140 degree day?? That fire sprinkler might feel great spraying out 60 deg water 😂😂😂

I watched the livestream regarding the nitro. Totally understand. Thank you

Good to see others donate to your channel. Im planning to donate once a year like a yearly subscription. You and Dick Wirz book gave me so much knowledges into this field. Thank you

👍🏿

Everything important likes to break on Friday afternoons 😊

Thank you

Why they instal a service port on the discharge side?? Really??

Is welding leaks a long term solution? Or will different places keep leaking in an older system?

question about the Swadge thing, are you preheating it before you do it ? :)

The senior tech at my company says i can’t refer to a low sight glass as a flashing sight glass. 🙄. He just says to use low sight glass. Is this correct in your eyes? It seems like he’s just being a dummy

Do u ever use refrigerant dye?

How come you didn't put nitrogen into the lines before brazing? Doesn't the air in the lines make carbon inside?

Love your videos my friend, thanks a lot.

Nothing worse than getting a worm draft beer!

I think it's the vapor pressure of each refrigerant that changes how many pounds can be put into a standard cylinder

I get educated....thank you friend!

Awesome video enjoy watching

Stratus for the win. I love it....Definitely the best leak detector I've ever owned. I had one of the OG's....the H10G....i loved that, but it was stolen from me. I bought the Stratus last year and its paid for itself in finding tiny leaks. I use an A17-15 tip on my torch lots of larger suction lines that are 2"+. Supposedly the A17-15 is good up to 2⅝" pipe.

No nitro while brazing?

Hey Chris why don’t you use staybrite solder to fix those leaks ?

its a joy watchin your videos! your attention to details, your approach.. amazing! Plus i learned so much from you! You are a proper guru of the trade!
