How to Charge by Superheat With the Fieldpiece Joblink Probes

Bert uses the Fieldpiece JobLink probes to charge an older R22 Piston system to the proper Target Superheat quickly and easily. So whether you are wanting to know "The right way to charge an air conditioner with Freon" or you have more refined interest in how to use wet bulb temperature to calculate the target superheat, this video has you covered.

You wanna pay 3 grand for an R22 leak repair or 300 bucks or some gas? lol. Not his choice but the customers dum dum

[@anthonynunez164]

That bleeding didnt look right lol. That air went right into the system.

[@scottm3552]

if the system was off how would air get in the system? looked like the system was off, he purged the hoses after he connected to the refrigerant tank.

[@scottm3552]

it actually sounds like the system is running but maybe it was an editing error.

[@enduringpromise]

Thank you,I was wondering if that was correct as I am still learning.

[@Cougarscream]

Guys, come on! This video’s purpose is to teach techs how to charge a unit with job link probes... the video’s purpose is NOT to teach proper procedures when dealing with a unit low on charge.

[@HVACRSurvival]

The way you bled the hose before adding freon didn't look right. Hate to be like everyone else and judge every little dumb thing when you're just trying to prove your point but some viewer's are watching with very little experience. Your valves were open on the system and at the tank when you bled your hose, so any air was already pushed into the system. Good video otherwise👍🏻👍🏻

[@jacobharrison1338]

HVACR Survival Maybe the service valve was front seated? With his set up that’s the only way I saw how he could have bled the hose correctly,Or if he did it before he hooked the charging T up.I doubt it since the service valve cap was on.. I’m newish so what I said was probably wrong 😁

[@mrcrux213]

Yes!! he did put noncondensables in to the system but not big deal 😬😳 shit's happened 😎

[@cleansebob1]

No, air didn't go into the system. The system is under pressure, probably at least 50 psi even when off. The air was pushed out of the hose by the refrigerant (and the system if the schrader was depressed), around the male end of the tee / service port, and into the atmosphere.

[@productionoperation]

One thing you might want to add is that You may want to find the source to why the system is low on charge to begin with before adding. Also when we need to charge using super heat with fixed device how important is our sub cool? Next video? Thanks

[@chaunceyturner871]

Superheat should always be done with getting sub cooling also

[@jasonreitz6049]

Just a question, if I bought that kit and added a 3rd psychrometer probe to measure the outdoor dry bulb at the condenser, would the app automatically calculate the dry bulb from that probe to calculate target SH, or do you have to enter DB manually like you did? I'm just debating whether to buy the extra psycrometer probe or not... Thanks.

[@hernanjoseprietoherrera4839]

Did you get the answer? Let me know. Ty

[@416RG]

I would love to get an answer as well. Did you get that third psychrometer?

[@jasonreitz6049]

To map it just go to the probe manager in the toolbox.

[@joserodriquez4270]

So, with those probes you don't need gauges..

[@kevinbennett2565]

@2:55 nice uv light shining through the return grill hahaha. Hope the dog doesn't lay there .

[@namskramskram6009]

It's against EPA regulation to add refrigerant to a leaking system... lol

[@HVACRNorth]

good video

[@victorvillafane252]

You’re crazy but do you make so good video thank you sir

[@Truthh4040]

so if it was r410 a ,,, we only charge it via liqiud ?

[@davidberens2189]

Yes. Because the r400 series are a mixture and the different components evaporate at different temps. So it needs to be used as a liquid.

[@billybbob18]

Always as a liquid for 410a. Loading as a vapor is as bad as loading the wrong refrigerant(which is technically true).

[@mychoclabwinston]

Wooo Hoo, R22 gone next year,

[@rossr4222]

No you find and fix the fucking leak first. Like a real tech would...

[@Michael-ig8ne]

Ross R you understand this is just a video showing how to charge using superheat with this equipment and not a troubleshooting video as to why it’s low on refrigerant, right? Why don’t you chill the fuck out super tech.

[@BillNickerson]

Im no tech...and I feel fine.....lol.....

[@billybbob18]

Those smans are surprisingly durable. I just bought the sm480v and plan to keep it for a long time. I hope they work out the kinks in the app that others reported last year. Data logging is a must. I was able to connect to the app without issue so far.

[@JuanHernandez-vt4wt]

Good video

[@BetterMechanical]

what's with the music?

[@rj.parker]

Nice work and excellent editing

[@DB-zh3ti]

OBNOXIOUS LOUD MUSIC IS NOT NEEDED. This is suppose to be a video to charge a system. At the start you said the system was low on refrigerant. Hopefully you found the leak and fixed it before charging the system.

[@rossr4222]

100% the leak is in the evap

[@anthonywoo3431]

Would you guys be able to make a video on the FP probes using My measure quick? Thanks

[@HVACS]

Anthony Woo will do! It’s on the list

[@rossr4222]

Purge air? You completely did that wrong lol. Now you have air in the system

[@michaeldower4335]

Great video and demonstration.

[@BridgeWater94]

Can I ask why you put your clamp on the liquid line after the dryer? I was always taught 2-3 inches away from the condenser

[@greentea111]

dude you are awsome

[@rojobandito318]

Nice werk Bert

[@coldfinger459sub0]

Excellent video we need more videos like this to inspire and show the young technicians just coming into the field how to use tools so they’re not intimidated. The only problem My son and I have the Fieldpiece sensor kit and the range sucks (“ unless it’s a simple wooden structure for the signal to go through the walls it does not matter how far sensors will connect in open free air with no obstacles in between at line of sight in the real world we don’t work with in line of sight”!.) in the past several months I use them every day or try to the buildings with brick or concrete walls or just one floor with a concrete floor below you spend more time trying to connect the signal move your phone around or move your senses around if you had to charge by the hour while fiddling with the Fieldpiece software you to go bankrupt first in the real world. But I do like them for simple close proximity jobs I give them a thumbs up in that situation just waiting for them to come out with some better range in depth to penetrate walls in commercial buildings and office buildings. Until then I would wait before purchasing the sensors until they come out with the next generation then I’ll give them a try once again. For those Techs who purchase the Fieldpiece sensors a little word of advice for some reason the Fieldpiece sensors do not always work very well with the Fieldpiece software download the Measure Quick software and that usually fixes fieldpiece sensors problem with connectivity and reliability issues.

[@tonymckay9031]

Good stuff 👍 I've recently wanted to learn the difference again between checking suction pipe temp/ superheat at compressor vs evaporator.. with the new probes, it seems more possible to check at evaporator, but why again?

[@tonymckay9031]

I suppose at evaporator would just be more accurate statement of what work the evaporators doing. And at the compressor would just be to make sure no liquid comes to the compressor. And then I suppose some manufacturers might specify if they want it at the evaporator or compressor

[@whitesheatingairappliancer7101]

Great video thank you.

[@frankl6684]

Your comment about the 0 superheat at the evap coil is wrong. The evap coil in flooded at 0 super heat therefore refrigerant is NOT evaporating in the coil. Also the way you were bleeding your charge line is wrong. You should have bled at your bottle with its valve closed. Your line was hooked up to the system that already had charge in it which would have pushed air in the line to the bottle.

[@Triaz357]

The bottles have check valves. You can’t push air into them. Or refrigerant for that matter. And yes a 0 superheat evap coil would be the most efficient, but you would have no protection from the compressor slugging. Just like he said.

[@jasonsherrill3518]

@@Triaz357 you are missing his point as to why the tank valve should've been closed. Sure, it has a check valve and thus no air or refrigerant can enter the tank. His point was that the valve at the tank should be closed in order to be able to bleed the air out of the lines at the tank. Instead, you tried to bleed air at the unit from the pressure of the open tank. Sadly, this same pressure from the open tank already pushed any air in the lines into the system.

[@Triaz357]

Jason Sherrill That could very well be what he meant but it was not what he said.

[@rossr4222]

Point of being a technician is to find the leak and fix it. Not just add more refrigerant to the system that will leak to atmosphere. Fuck

[@techfive7202]

good to know if i ever need to go to outer space when checking charge. Thanks

[@Stuart68505]

Was the unit valved off before he purged the lines? It looked like the schraeder valve core was already depressed when he purged the charging hose. If the unit’s pressure was less than the charging tank pressure from say the tank being stored in a hot truck, then the air in the charging hose would have been forced through the open schraeder valve into the unit’s system before he purged the line.
