- This was a video where I returned and replaced a bad TEV on a walk in freezer. The system had a really bad design that made me have to recover the charge to change the drier.

I did my apprenticeship not in service but in building chillers, mostly for laser cutting application. Happened that I also did half a year doing service work and after watching a lot of videos on your channel I am so disappointed how much harder the job got for my colleagues and me just by not having tools nearly as sophisticated as you can present here on this channel. Such small stuff like a micron gauge that has no problems with positive pressure, so it can be easily removed without disturbing the vacuum.
Stuff I had to verify complicated or had to make assumptions on, you can present clearly just by using the right software and probes. If I ever have to go back I take a huge amount of inspiration from your videos.
That Sporlan kit is excellent. Organization is essential to saving labor and time.
I love that kit! I will be going live on TH-cam this evening 10/14/19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from the LiveChat, TH-cam comments, Emails, and Facebook comments come check it out if you can. th-cam.com/video/tB11ZTSHhhE/w-d-xo.html
The right way to do this is to purge nitrogen when brazing and your pretty much the only person outside of school I’ve seen braze with nitrogen ! Love you videos cause everything is done right and no short cuts cause shorts cut equal bad work
I'm certainly not perfect and there have been plenty of times that I didnt use nitrogen while brazing. Some situations you just gotta do what ya gotta do. I try to follow all the best practices but sometimes you cant

HVACR VIDEOS yeah that’s understandable and it’s always best to practice and do it as best as you can all the time to make sure installation is 100% cause then the unit won’t last long enough or you’ll get call backs . I’m not perfect and I’m still fresh out of school so you know I make mistakes that’s just how you learn from it
Dude, your channel rocks! you truly are a great technician, for real. I'm gonna watch all of your videos, keep it up brother!
I really enjoy your videos. I always remove the line set quick connect fittings, they tend to leak.
Sponlan/alco valves suck. when failing they flood! a Danfoss does not fail often, but when it does it shuts off. also the Danfoss kit is much more refined and needs no oil or rubber gaskets. Great job though Chris, really like your videos. Nice to se how its done in other countryes
hi chris --has always great video thank u so much ----that boxe looks very very nice and relabel

Expansion valves and power heads. Nice sporlan kit. Good job.
Another comment in regards to the sight glass. Put it upstream of the filter dryer. With age and use, the filter dryer can cause a pressure drop and flash gas even while the charge is correct. With a roof unit the weight of the refrigerant will take care of the flash gas before reaching the expansion valve below.
Damn you man! West coast wanted to find a fault with east coast but you didn't let us! Go easy next time.
I really enjoy your videos. Thanks!
Nice job ,
Keep up the awesome work and be safe !

Walk-in coolers I like to use Penn A19 electronic controllers. I get tired of screwing around with those manual thermostat since not much more work. I have a wire ferrule kit on my truck that makes it really easy 2 hook it up into that small wire connections. Walk-in freezers we have a few of those are not as critical but if you had a freezer that was a critical temperature I would put a electronic control in that as well
Keep the videos coming! Great job
Gotta love the Ol Mechanical tstat. Good vid

no wet rag on the solenoid valve? I will drop an evap unit to work on a bench - takes longer but I get it built up nice
I think Sporlan would be a good sponsor ... Lol ...Good vid as usual ... Much appreciated ...

love the new case, would love to see them stocked in the supply houses. They want to charge freight to get them.
I talked with them and they are gonna make a big push of their BQ kits soon so they should start showing up in the supply houses sooner than later!

@@HVACRVIDEOS I really appreciate the feedback. That is an amazing kit. Which one would be the best for residential work. That can win you a lot of after hours and weekend work
Great video
NICE VIDEO DOUT! YOUR LUCKY, IAM WORKING ON STEAM AND HOT WATER BOILERS NOW.
AT THE 5-6 MINUTE MARK YOU REMIND ME OF "REPO NUT", GOOD STUFF. THANKS.
Wow I used to watch all of Reponuts' videos. it was super sad when his wife passed away? what reminds you of him the black gloves i was wearing or just the style of filming? Did you ever see the video where he stopped at an accident and gave cpr compressions and brought the person back to life?
@@HVACRVIDEOS you in glasses , profile, gloves ect, yes his passing of his wife and his dog was so sad. i hope he is doing well. no i did not see that vidio, i thought i seen them all, any info so i can watch, thanks DOUT.

Always complete and thorough though you don’t address the real issue. Again, no pee trap! On your last one like this the system was full of oil when you did the repair including changing out the TXV valve. Simply adding the required pee trap would prevent the oil staying in the evaporator coil and more specifically restricting the expansion valve.
It actually had a pee trap but it wasn't a giant one but it was big enough to be effective.

Dude! That case is sweet!
Really like that new carry case for the txv kit they should stick with it in my opinion
Did you get a new camera? This video seems to be *much* higher quality than some of your others. It looks great, keep it up!
There is a rotating knife in those Webster pumps that takes the place of the filter screen.
Good stuff.

Soldering has the same AWS definition as brazing, except that the filler metal used has a liquidus below 840°F (450°C) and below the solidus of the base metals. Soldering can be considered the low-temperature cousin to brazing.
Looking at the indoor fans it actually looks like a condenser it self looks like it’s built the same way as a condenser unit
We call em TXV here 😁
I was taught to reduce oxygen slightly on the torch from a neutral flame to prevent an oxidizing flame that leaves pinholes, and the envelope of the flame will flux the copper removing the surface oxide. It is hard to tell in the sunlight. Are you running a small feather? I think you are as it is larger than a typical cone. The copper fluxed very nicely in the envelope.
you could turn the liquid line valve around backwards, but I doubt there's not enough space to use the service ports.
I wonder if it was just an engineering error, but more likely to be cost cutting tomfoolery.
Very nice good job
what is that thing he's using ? VCRT? on the king valve?
One of the hobby guys that I watch does this thing where he takes his solder and bends it into a rough ring then slides it over the piece he wants to solder. how well or bad would that work in a situation like this?
Have you ever thought about fitting Carel EEV'S to any of your walk in cold rooms and freezers?
You should have a small step stool, and have a 3M mask. What's the size of the TEV? 0.5, 1, or 1.5 Ton? Another great video!
If I remember correctly it was a 1 ton valve, I will be going live on TH-cam this evening 10/14/19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from the LiveChat, TH-cam comments, Emails, and Facebook comments come check it out if you can. th-cam.com/video/tB11ZTSHhhE/w-d-xo.html
He mentioned specifically the valve body and kit used. It's the blue kit.
Anyway im a big fan of your work.

I thought about getting that umbrella. Johnstone’s has it. Is it pretty sturdy?
It not bullet proof and the magnet could actually be a little stronger but overall its nice. I would buy it again if I had to!

I use an old pool umbrella. It's 7' diameter and works great for sun and rain. Not so much for me getting wet, but my tools/recover machine. It's strapped to the side of my 6' ladder so it's always available quick.
We only use straight acetylene turbo torches here , they work well and I don’t have an 8” flame spitting past my weld, why does everyone use oxy acetylene ? There is no right or wrong, just wondering.
Its quite a bit hotter :) In HVAC that's not so important but if you do larger joints with huge heat capacities you will notice a big difference.
Curious as to why there is no oil separator or suction accumulator? Here in Australia very rare to see a freezer with out them
Andrew Mattas same here in Canada, maybe it’s a Commonwealth thing?😁🤣
The point in an accumulator is to remove any liquid I'm guessing since its not a very big application it doesn't need it
Nice job...

The one thing about cases i have never understood is why on earth can't they decide which standard to use? I get they don't want to pay licensing fees for proprietary standard but there are so many open ones as well...
All my Tools are in L-Boxes, they are awesome, durable and very practical because to connect to each other and i don't think Bosch owns that standard because there are certain other tools that can be had in L-Boxes too.
Chris do you know anything about pro press. Basically dose not use a torch or flux
I will talk about press fittings on my stream tonight , I will be going live on TH-cam this evening 10/14/19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from the LiveChat, TH-cam comments, Emails, and Facebook comments come check it out if you can. th-cam.com/video/tB11ZTSHhhE/w-d-xo.html
Pro press isnt the only brand that uses non brazing correct? Isnt there a few others!
Pro Press is an alternative for plumbing soldering, It uses o rings. It is not a replacement for a hermetic brazed seal. Not sure if the o ring material is suitable for hermetic applications involving refrigerants, oils, and possibly acid.
Please what is the name of the equipments you use to collect the Refrigerant from the system I want to buy it. Thanks
Appion refrigerant recovery machine
Thanks for your reply.
But does it have a specifications?
🔥🔥🔥
Where did you get the HTPG coil number information from? Was it on the evap. nameplate?
Yeah it was part of the model number from the nameplate.

Hi Chris, any help in shipping tools here in Philippines? I inquired in truetech tools but it seems they don't ship here in our country.
better to start brazing upstream of nitrogen , just a suggestion, good videos
Your not alone l was always favor of Sporlan wasn’t big on on Alco valves.Why didn’t use a electrical thermostat haven’t use an A19 mechanical thermostat for over 10 years them thermostat they get out of calibration essentially when you have the heath inspection .
I forgot to quote a temp control and I really wanted to change it so i used the cheap mechanical one, I will be going live on TH-cam this evening 10/14/19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from the LiveChat, TH-cam comments, Emails, and Facebook comments come check it out if you can. th-cam.com/video/tB11ZTSHhhE/w-d-xo.html
Just curious do you use stay-silv or stay-clean flux?
Flux is for soldering. For copper brazing a flame envelope on the torch is devoid of remaining oxygen and it fluxes the copper shiny for brazing. It is completely different than soldering. Soldering flux is completely burned and contributes to contamination if used for brazing.
Hello friend!....That cooling putty.....I haven't seen that before...what is it called and I purchase some from United Refrigeration or Baker Distributing?
Yeah its called Viper Wet Rag by refrigeration technologies.... they have it at my local United
At some point it seems like the fix to a flooding valve was just to add more refrigerant 🤷♂️
Subwoofers beware of the Nitro tank. That's a deep bass drop.
I always avoid putting the solenoid valve inside the evaporator case if possible, it just makes everything too crowded and uncomfortable to work on... I realize this was a R&R and you were trying to get it done, so I’m not bitching at you Chris... I’ve seen those receivers with no king valve, wonky setup, probably designed by an engineer who never was in the field before. Good video, thanks!
No reason to recover it?? Just use the existing liquidline valve to pump down. Then if needed just add another drier on liquid line after king valve
and you must wet rag solenoid valves... of Danfoss type, they have a fibre disc inside that can melt.. dont know about sporlan soleoid though
hi, just a question for solenoid valve no need to keep it away from heat?

I rather dislike doing TEV replacements. Never enough room to work comfortably.
Hi
#266 Thumbs UP
I would rather be accused of using too much brazing rod versus chasing leaks. All the guys that ever bitched about my brazing chased leaks. Guys that do not know the difference between brazing and soldering and thinking a braze joint should look like a solder joint; plumbers?!?! Lol.
The more you use (Filler Rod), the less you lose (Refrigerant)...
21 minutes when you need three hands...
Hey chris , i sent you an email, could you give it a quick read .

Just like a butcher....hacking away at pipework and ropey pipework to your expansion valve!
Not a neat job at all.🤣🤣🤣
How would you have done it differenty?

I can see from outer space your a total pro with all the skills but DAMN why you selling them all those parts??!?!! Seriously tho. That bill is going to be half the price of a new unit. Let’s say another major or even med component goes out in the near future, which would not be surprising at all looking at that unit. Then what? More money??? That’s just nuts. There’s more to being a good tech than just fixing things. Respectfully
The customer made the decisions to repair it, essentially they wanted it fixed asap and did not want to wait to replace it
I will discuss this on my Livestream this evening 1/23/23 @ 5:PM (pacific) on TH-cam come over and check it out th-cam.com/video/MkAGiy6pwh8/w-d-xo.html
