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
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.
Thank god for RUclips. 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!
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!
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.
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!
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.
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.
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! :)
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.

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.

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).

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.
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
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.
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😂😂😂😂
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.
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👍
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.
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. :)
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.
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.
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!
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. 🤪
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.
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.
The yellow jacket torque wrench is a good one. The size of it easy to use and accurate with the torque. It has been in the market for a while with no issues.
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
I’ve found sometimes with the 400 series refrigerant in hot weather those sight glasses just like to flash sometimes. In this cases I just go off of the pressures, and make sure the super heat is good.
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.
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.
Pressure variation doesn't change how much liquid the cylinder will hold. Liquids are not compressible. The density of the liquid determines how many pounds can be put into a standard cylinder.
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.
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 😄

No wonder you got outsmarted by the wrenches, you forgot to yell "Click!" when the flares were tight enough!
If im uncertain about sightglass either full or empty, i always pump it down lf it has a tank. That way you can tell!
Johnstone carries those spark igniters that Chris uses for his torches in case anyone needs one.
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.

that's a moisture indicator and it changes color if there's moisture in the system or when new and not vacuumed down/charged with refrigerant.

I think it's the vapor pressure of each refrigerant that changes how many pounds can be put into a standard cylinder
Pressure variation doesn't change how much liquid the cylinder will hold. Liquids are not compressible. The density of the liquid determines how many pounds can be put into a standard cylinder.
