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!

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.

[@BowlingHeyday]

All information is coded digitally to the computer in the Inteligent module. The other thing that you can probably do with the interface is take screenshots and move them to a thumb drive. In later scenarios say 1 or 2 years down the road, a technician can pull them up for that unit for reference if troubles occur. And if enough Intelligent modules are being used in your service area, a library can be started. Of course, even a users Bulletin Board on the web will clear up any expected troubles and compare to known good data.

[@xzearr]

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

[@eeeeweeezeee]

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

[@DelticEngine]

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.

[@HighTechLab]

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.

[@atsimas]

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.

[@jeffreyhueseman7061]

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.

[@daleborg9070]

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.

[@chriswhite7193]

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.

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.

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.

What is the middle part in the sight glass for?

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.

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.

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

[@mikixyz123]

if the copper is very beat down and pitted out, then yes, fixing a lead might create another. Other than that, yes, it is a long term solution. I am not in the field though, I'm just an watcher, so I'm making an smart guess based on Chris's videos.

[@LadyAnuB]

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

[@stargazer7644]

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.

[@nikothrushman4932]

Do u ever use refrigerant dye?

[@henningquast8456]

Please don’t. Not only is it unnecessary if you got a digital leak detector and soap bubbles, there‘s also a possibility of dye damaging internal components of the system, especially the oil and the compressor. Imo only a hack uses dye (not saying that there aren’t some uses for it).

[@HVACRVIDEOS]

I prefer not too, it makes a giant mess and is unnecessary when you have a good leak detector

[@jollygreen4639]

I used it sparingly depending on the situation and what location the unit is at. An example is two Aaon units on a roof the was in an open area of the buildings. I knew I had leaks and could not get precise locations on the condenser, in this instance. I used bubbles also but couldn’t pinpoint it. So finally put dye in it and let it run for a day or two. Went to the unit way before sunrise, at 0430 or so, and used the UV light. I found, and then confirmed with bubbles, so many leaks at joints and bends that we had to replace the coil. So in my opinion, it depends on the situation.
