Setting a Refrigerant Charge by Subcool

[@jericosha2842]

i don't grow tired of your videos. This was a great demonstration of using core deppresors (how is this not the standard yet?) and the probes.

[@00ABBITT00]

I can’t express in words how helpful videos like this are for those of us who are dedicated, hardworking and most importantly, interested in this trade but may be slower learners than others. I never feel demeaned when I watch these videos and for that I thank you.

[@terryadams5335]

I've always enjoyed drinking from fire hoses! I earnestly appreciate your teaching/presentation style. Please continue your excellent work.

[@Vic92]

I have no more than 2 years on the hvac trade and from the very first day I start watching your videos, now im on level 2 NCCER Hvac and refrigeration course and my hvac skills skyrocket thanks to this channel, I was nominated as best junior tech on the company I work and all this was because of this channel, there is so much high quality info that you can learn here.

[@Gary-ts6dh]

1:00 - True to Bryan Orr form, we're told were about to see one thing and then he does exactly the opposite (0:00). Thanks for keeping us on our toes, Bryan. I was anticipating seeing how to charge by Subcool using only temperature probes.

[@drdickqueso]

Field piece literaly does all the work for you now. It’s so cool how it tells you what is happening and it’s usually accurate and even tells you the fix. We are so lucky 😂

[@Chaomhainn]

Nice presentation . Good to actually see an instructor out in the field not just in a class room . Bryan you give much more than I could have imagined . Cheers

[@SSTW]

Thank you so much for being such a great teacher and having the patience to share your knowledge tirelessly and effortlessly I'm so blessed to be able to have access to your videos. You are really appreciated sir!

[@luisbenitez3428]

one of the best videos out there illustrating and teaching how the HVAC system works, especially... showing how to set up the equipment, reading an understand the unit in operation, thanks a lot man, you're a excellent... instructor.

[@jamestamu83]

Best HVAC technical channel on KZbin! Learned a lot from watching your videos. Thanks for sharing your knowledge!

[@zachosborne6577]

Love my analog gauges, they’ve served me well for many years.

No wonder there is no dislike on these videos, Your videos and teaching method is class A and really appreciated, Thank you

[@jmead6121]

Thanks for another Great Video & tutorial ..I also love & use the core depressor tool for hi side sometimes or ball Valves & Lo loss fitting combo

[@100bfriend]

I've been retired for 20 years, this was a good job and nice video... I see I need to buy some stock in a battery company 😁😁

[@SuperVstech]

Note the data plate specifies 10degrees sub cool AT the evaporator. Your subcool measurement outdoors doesn’t take into consideration the heat gain from the long uninsulated liquid line. Especially important in attic evaporators with multi story homes.

[@armorhandyman5062]

Thanks for the demo and the explanation of all the tools as you were using them - that was awesome.

[@francisbriggs76]

Very good teacher! Easy to understand.

[@georgesharrizon7293]

great procedure Bryan! accurate and up to standard. we don't have instrument like that in the Philippines I wish we could but we used TANTYAMETER here.

[@brianpipkin9214]

Loved it man! Awesome video for learning to become a better technician

[@purrungas2012]

Top of the line details...thanks really appreciate the way you explain things

I liked watching a sevice

[@rickbraden4272]

Always very good. Thank you. Question is how come the 410A jug isn't rose colored?

[@Mikecianfrocco]

Great video Mr Orr! Is la Croix a sponser now?

[@philkuchle7508]

Question what is the name of the blue adapter that is put on the refrigerant tank to limit flow? this is at the 16:37 time in this video.

[@johnathon9056]

Replace your hose seals and turn the depressors in using a valve core tool, lossless hookup.

[@Brisket9392]

When finished charging, close the tank valve and then open the charging hose up so no more liquid is in the hose. Prevents a hose full of liquid into environment.

[@loganc339]

Never met a tech that cared even slightly about letting refrigerant loose to the atmosphere..ever

[@rickbraden4272]

In all honesty I think you drank way to much of the alarmist kool-aid. I ways do what you suggested but it has to do with not wasting it.

[@holtrussell]

Excellent demonstration! Does bleeding air out of the line as a vapor go against best practices due to the need to keep the blended 410A mixture ratios correct? I would think that bleeding lines with a blended refrigerant would be best done using a liquid. Maybe that’s not a concern.

[@ralphriffle1126]

Very informative. We know your tools are yours. You can skip saying, MY. My This, MY THAT, MY EVERYTHING.

[@Jetski270]

[@pleasecho2]

All this nice gear and you guys are still using Fahrenheit and PSI?

[@Pennconst101]

2:50 Fun fact, Goodman/Amana recommends charging in low stage only

[@donnierobertson3088]

Great job and video like always

[@Pete9999100]

I missed the port you added charge. Was it the low side port or high side port ?

[@Waymanator123]

Could you list out all the tools you used in measuring the refrigerant? I'd like to purchase some of these tools for myself. Edit: I found the gear, thanks!

[@jrsmyth9761]

How much additional charge was added? Why not add an additional temp probe for the OAT and then it will be automatically input? It is a heat pump sitting flat on the pad. I guess there is no freezing happening in your area and if this goes into defrost the water will not freeze on the outdoor coil?

[@ricardosanchez1930]

When purging the line with vapor from tank, doesn’t that cause an imbalance in the refrigerant tank due to r410a being a mix?

[@DayClanTribe]

It's negligible with r-410a being near azeotropic mixture.

[@ericsosu7867]

Please which app. Do you used in your calculations

[@gtpforever]

Whats the model number for the temperature clamp you used??

[@iancunicolae2626]

is it ok to have 13.5 subcooling on a 10 +- 2 Target? per manufacturer? Only slightly higher amps? Will it perform better in heatpump by having more freon? in the winder when the volume goes down due to the cold?

[@sauliusvausha4964]

[@spok209]

does the device need data or good phone signal for the app to work ?

[@acetoday1]

Can someone provide links to the core depressor and blue (small orifice) charging tool

[@sultanhong]

why ur R410A bottle is not in pink colour?

[@SuperVstech]

Refrigerant standards are changing all refrigerants to the beige color, forcing techs to READ the numbers on the tanks… supposedly reducing contamination of refrigerants.

[@piezomotor]

Thank you for this video. Originally the blue gauge showed the saturation temperature of 20 degrees F (Pressure 43 PSI R22). At the same time the temperature I measure on the blue line next to the charging port is 80 degrees F. Thus my Superheat is 80 F - 20 F = 60 F. The pressure at the red gauge before charging was 200 PSI that corresponds to the temperature of 102 F. When I charged the system from the R22 recovery bottle, the Superheat changed 75 F - 26 F = 49 F. my red At the same time my red gauge after charging shows the pressure 225 PSI or it is the temperature 106 F and I measured the temperature of the high pressure pipe was 106 F. Question- is my system is overcharged now of I should continue charging it?

[@warningthetacohasagun8562]

Just wondering how many people here use sub cool or super heated, or beer can cold and how many add ten Mississippi of that cold juice!??

[@dustyr.647]

Where do i get that charging tool

[@jacodejager5462]

Hi what app are you using

[@Silky_boi]

I’ve noticed these new inverter systems are much more sensitive to overcharging so analogue gauges just have to go. Good quality digital gauges like SMAN are ideal. Not a fan of these probes as you have to be tied to your phone.

[@bleisaint00]

Can you use those wireless probes in r410an and r22?

[@shawnfanning8519]

Your video are great

[@zyxnix]

I got to get all that equipment. 😃😀

[@haroldcouch4168]

Amana says charge in 1st stage.So that means in low airflow and only 67% compressor capacity.What do yall think of this?

[@ryantoner8132]

Wouldnt we just recover on a heat pump and weigh back in?

[@megalomani4k]

What brand of charging tool did you use?

[@daywlkr8]

Can anyone explain to me why it showed 0 subcooling when measured with the analog gauges but the digital gauges showed 7-8 degrees of subcooling?

[@CHOPPA78]

Gloves guys !

[@Stuart68505]

Very helpful. I will need to learn how to use MeasureQuick once I buy the digital tools. I wondered how it takes a measurement of the Freon that is being put in the system. I just have the old fashion digital scale at this point.

[@davidjiang8435]

[@wes4477]

Still like my analog gauges and i dont need to worry about dye or anything like that you would with digital gauges

[@ronaldpalmer1241]

Sorry but I am confused. In the video you said that the large line was he true suction line. I thought that most units had a true suction line, usually on the same panel about the 2 service ports but sometimes inside the unit. I thought that the service port suction line changed in heat mode, and that you had to be hooked up to the other suction port (true suction) in heat mode. I thought that the small line liquid port remained the same in both modes.

[@tinymanthebeast]

A lot of new people are getting the testo smart probs or filed pice probs with the clamps and the app .

[@Captain_Kdawg]

good video goes to show you. That not every jobs going to be exact! as far as the measure quick app!!!

[@joseramonherreramendoza9260]

How come charging up side down liquid in to the low side system? I didnt get it 😅😅😅

[@lordjaashin]

he is using that blue color charging attachment that slows down charge rate and converts liquid refrigerant to vapor refrigerant.

[@davejohnsonnola7908]

Blue adapter is a tiny orifice that makes liquid charging leaving the tank, vaporize before getting anywhere near the compressor. No risk of "slugging" compressor.

[@micahjames5663]

Because you supposed to charge R410A as a liquid…

[@SuperVstech]

Only pure molecule refrigerants are supposed to be charged as a gas. The mix refrigerants (the ones that start with 4) are mixtures of different molecules. The mix needs to be added to a system as a liquid to maintain correct mixture of the molecules.

Does this app work with other devices than field piece?

[@davejohnsonnola7908]

Measurequick app allows one to mix and match Testo, Fieldpiece, UEI probes and other meters.

[@yodamanrulz176]

When pointing out the true suction port, perhaps you could obscure what you are attempting explain a little bit more by more hand/elbow in the way and a more sad camera angle.

[@garza7676]

I have a 5 ton carrier unit that replaced a 3 ton unit few years ago .At the time the HVAC salesman lied and told me you should get a bigger unit . Fast forward 5 years later and I just recently finished HVAC school .The other day I plugged my Testo 550 gauges and couldn't get more then 5 degrees of subcool ,data plate recommends 10 but my superheat was @ 8-12 and have a 20 degree split from my RA AND SA vents .Outdoor temp was 105 (Vegas heat baby) I don't wanna keep adding refrigerate just to get the recommended subcool and risk flooding my evaporator ,and returning back to the compressor .So I do have a starved condenser .I told my instructor and he feels the unit it to large but which I agree . What are the risk of having a starved condenser ? Do you feel I should let it be ?

I realize this has nothing to do with a video but you guys said you installed this unit The corrugated pipe that comes out of the ground that the line set is going through is wide open doesn't that allow rain water and/or snow if that happens in that area to get in besides rodents and other pests?

It might be a 2 ton system, considered "small", but it holds 13 pounds of R410a and that's not small at all. Why so much? My 3 ton only holds 5.5 pounds. Do all heat pump systems use a higher than normal AC refrigerant?

[@SnowyOwlPrepper]

Accuracy and precision are different. Accuracy, temperature wise, is how close a number is to a standard (actual value). Digital and analogue can give the same number. If that value is accurate (traceable to a standard)both are accurate. Precision on the other hand is how close can the device comes to a value. A wide needle doesn’t allow you to be precise. Precision is the plus minus the instrument is capable of in the design. Digital readings are usually a percentage of the full scale of the measurement being made. Good information otherwise.
