Chiller had high SUPERHEAT cause of this

- Trying to finish the final repairs for this compressor replacement to call final startup good. You never want to just assume things are good when replacing compressor because there's almost always something that killed it. I also show the EXV calibration procedure for this York air cooled chiller. Easy test any hvac technician can do to test the condition of the EEV. I was also able to fully test the recovery ability of the NAVAC NRDC4M recovery machine with fantastic results!

finally an hvac channel that does some real commercial stuff. good stuff!
I love it
Sweet recovery 🤤
Does it add that much cost to just replace known failure points (EEVs, sensors) while the unit is being repaired. Is it something customers will not go for because of the increased cost. It had to cost a few thousand to remove refrigerant and replace the valve.
Do you have a video about refrigerant free cooling pumps?
One of the last times I worked on a YVAA i was able to pump 220 lbs in less than an hour by just letting the compressor do all the work. I hooked up to the liquid line and let the circuit run until it went off on low pressure. Was able to recover the entire charge (270lbs) in less than 5 hours.
Haven't worked on many York chillers. They seem to be problematic. Where I'm from most Trane, carrier or AAON
They have the same issues the rest of them do. Just comes down to age and stress. I have a lot of York chillers so it looks like a lot of failures on my channel.
You know your stuff!
just started my second year working on chillers and boy do I wish I found your channel last yeah haha
Ive tried telling my guys for years, wires and hoses don't know WHAT COLOR THEY ARE! But it does help guys in the beginning.
Did a recovery this week , took me 3 hours to recover 40 kg / 88 lbs of 134a.
Let me just release a giant sigh ........
Brooo, i be trollllin mfers with my color choice all the time. I purposely set up my manifolds each with either all red all blue or all yellow. As long as i have a ball valve on the high side, im happy.
This is my next move chillers I'm an ok tech at commercial hvac but industrial hvac is nice and really want . But I do lack on refrigerant knowledge
Keep learning bro, you can be a great tech someday if you want it enough. If you're not willing to use up a good portion of your free time to learn it, then you will just remain an ok tech. Good luck
@Bryan Swanson thanks man I appreciate the advice.
Looks like a stepper regulator valve that failed, replaced one of those before on some older heatcraft unit.. could be wrong though.
Great stuff man, Always. Thank you
NAVAC four-cylinder I tested it with R410 I placed the NAVAC unit in front of a hot Condenser 115°F plus air and a recovery cylinder in the hot air flow intentionally and it still had no problem recovering refrigerant and filled the cylinder like it didn’t even know it was in 100° + heat
That’s 😂 that’s the right attitude 👍🏼
Whats a feed valve?
👍
I have a tip for recovery buy bag Ice 🤫
Sure it works but is an extremely inefficient way to do it especially when dealing with large tanks.
@@HVACTIME makes you wonder why there isn't a character in the Marvel universe whos mutant ability is HVAC/R. Enthalpic man or Heat Sink. Arch nemesis would be like, Dr Manifold Inhalf.
A lot of manufacturers won't warranty motors, if you don't replace the blades too
never once heard or was told that in 40 years in the trade 🤔
@@richardbartlett6932 what an interesting comment...why do so many HVAC techs feel the need to give their resumes? I'm sure your time of service is relevant somewhere, I guess. Thanks for the comment
@@rthompson968 I too have never heard this in 22 years in the trade and can tell you it's not true with any of the 30 plus different equipment brands I work with. And yes a techs years in the trade is relevant with just about any topic you wanna bring up. So bring it
CODE MEN YORK😑
Great job tho man
