SuperHEAT is amount refrigerant vapor is heated over boiling point plus pressure. It is confusing as it takes place where things are cooling. Your mind wants to think opposite. SubCOOLING is amount refrigerant liquid is cooled below condensing point plus pressure, once again confusing because it takes place where things are hot and your brain wants to think opposite again.
Semi retired HVAC service/Installer and former instructor...This is simple and very clear and the idea of marking the gauges, just plain smart...Thanks.
I know this is a random question but seen u were in the hvac field i recently installed a gas furnace with a 4 ton straight ac its a piston acoil .. an it doesnt seem to be getting cold. Everything is running fine and pressures are normal.. everything is new.. got any ideas on what could be causing this..only blowing like 68-70 degrees out the supply vents
I just got hired at a hvac company two days ago and I’ve been watching your videos along with hands on learning and I am doing amazing in the Field! Thank you for your videos!
HVAC school is a good resource as well. I would recommend giving it a few years if you ever consider giving up. There will be tough times and stress but it gets better. Welcome to the trade my friend!
A good teacher is someone that can put detailed instruction across in a simplified manner .This guy is able to do this incredibly well ! Thank you so much
Retired after 35 years,first 3 in residential and 32 years in commercial and industrial and I would agree with Shawn Green that this is a great video for beginners and even some guys that take there skills for granted. There are many times guys hook up low side gauges and don’t purge there hose and inject air into the system. Well done young man👍🏻
I’m doing a lot of refrigeration work, so I always connect high side first and purge low side through it, because with r134 you can get negative pressure inside with low charge
what an amazing video, i graduated with a diploma in HVAC like 10 years ago , i was taught with a lot of theories on an enthalpy chart on how to plot out a REF system ,calculate SH, SC, dew point temp bubble point temp ,quantity of HEAT ETC, that i have never seen in real life. just for me to get to this word of advice TV and i am actually understanding all if it gradually in the practice field., thank you so much SIR.

Go to a reputable school i.e. Community College some of the "trade schools" just are not doing a good enough job teaching. Slow and steady wins the race. But first be honest with yourself are you mechanical?, can you use tools?, are heights an issue?,the weather hot/cold/rain/snow?,long hours. Are you willing to invest in yourself and have the discipline to stay the course? You can make a very good living, the more you know the more you can make. Everyone learns at a different rate. But just be honest with yourself. when you make a mistake own it and learn from it. Nobody's perfect do your best. In the last 4 years I've had 40+ apprentices/helpers. 7 have stayed and continued on with a career not just a paycheck. 30+ years in Refrigeration.
As a newcomer into the HVACR industry (1st semester HVACR school) I can't thank you enough for putting this concept of SuperHeat and SubCool perspective (without all the smoke and mirrors instructors use though maybe not on purpose) using easy to understand words and a simplified guidance for using a P/T chart, manifold gauge and temperature clamp readings. Keep up the great work and I look forward to more instructional videos. +Eddie+ in Bayou Vista, TX
Out of all the techs on You Tube, you're the only one that has ever come up with a really cool way of remembering this, It's confusing when you say saturation, and liquid line temp, this is easier and I like it more, Great Video, and very informative, keep up the good work. God Bless Texas
man you are really good i am in school and learning Hvac and so many things i easily understand on your channel. You are very welcome to Chicago just let me know when you are here would like to be your host. thanks again and keep up with good work.
Man you are one awesome dude I learned a lot from watching your videos and I totally appreciate you sharing your knowledge with us…ok so now watch till the end people because he also teach you how to do back flips😂😂😂 seriously …Much love bro keep being awesome💯
Wow this guy is amazing. Hands down the best youtuber and teacher. I'm in hvac school n its hard to understand my teacher. But this guy right here, explains everything in detail n shows it. Thank you so much. I'm subscribed
I've been working in industrial refrigeration for 2 years. I just left my job to get into HVAC. Hopefully I made the right move!! I've been watching your videos... Thanks!!
I always purge through the manifold to parked end of the yellow hose. Both sides. Just in case air lurks in the manifold. Im OCD (!) PS best concise explanation of SC/SC i'v found on YT
Yes! Good attention to detail! If we're gonna vacuum down to 500 microns before releasing refrigerant into a new system, why screw that up with excess air from our gauge set hoses. By minimizing non-condensible gases as much as possible, it reduces head pressure and makes the system efficient and lowers their power bill. Air is added every time the gauge set is hooked up if we're not careful, and it adds up. That little bit makes a difference I think.
Some instructors think that the more complicated they make it sound the smarter they think it makes them seem. A lot of the teachers couldn’t make it in the field so they teach. I’m not talking about those who may have physical problems.
I really love the way you came out with that formula, makes it so easy to measure SH and SC, It couldn't be better than that. Thank you so much for sharing this tip.
Thanks so much for another great video. You do an exceptional job of saying what is necessary to explain things, without jabbering on about minimally related or non-related things. You're editing is spot on! Great job! Thanks again, David
Excellent video. Just one thought, you also may want to show techs how to get superheat value. Ex; your super heat was 8 but nobody knows if thats the correct value without taking temps at supply and return and then doing your math to get your target superheat. I love your videos, please keep them coming!!
I like the video except for the fact that if the tech is forgetting how to measure superheat and subcool then they are forgetting how the system operates and why the readings are important. Also I would recommend a better temp clamp, those UEI clamps for some reason do not last long and I've seem them read wrong out of the box.
@@teddycarter2618 that's a field piece type k clamp. The blue ones broke easily but they stopped making them and the new ones are now yellow and are much better.
This is awesome. Ever since the first time one of your videos popped up, I've never wanted to watch any other videos again. Thanks Jay, you are awesome. By the way, i haven't found any videos about ice makers, fridges or freezers, please shoot some videos about those as well. Cheers from Canada
Me watching this as a seasons refrigeration mechanic 👁👄👁. This is a great video man! Very simple to understand for anyone looking to learn how to measure SH and SC.
I’m on my fourth week of work as a service tech! I’ve memorized this like so: Red/high “good - Lord = SC. Blue/low “Lord - good = SH. I hate heat. So it works well for me. Lol. Boss just gave me a Fieldpiece digital four port gauge set, but I still use the old school gauges to hone my skills. I really appreciate your videos!!!
Jay Thank you for making it simple. I've seen other videos on the subject and none of them compare to you. Keep up the good work. Thank you again for the lessons.
Jay you have the bestHVAC channel on TH-cam hands down. Theres 2 TH-cam channels I watch consistently, yours and South Main Auto. I highly recommend South Main Auto if you like to work on your car.
I love you, bro. In the comment section of one of your other videos, I told you that your video basically inspired me to go to college for HVACR. Well, I start the Fall Semester next month. In the meantime, I purchased a 1,600+page book titled Modern Refrigeration and Air Conditioning, 21st Edition, by Althouse/Turnquist/Bracciano, to get a headstart. Thank you so much. Seriously.
Thats awesome bro!! I'm happy to hear that my videos played a role in your career choice. You'll love it! And since you're getting a head start on things, you will learn better in school I am sure. It helps to know what questions to ask. God bless and good luck. Become a legend out there!
Oh that! I should have probably explained better. I said the pressures were fluctuating because of the metering device (that unit had a TXV metering device). So I flashed the txv to elaborate which metering device is doing that
Yes. With a TXV you measure Subcooling. However, it is still good practice to also measure SH which should on average for residential be between 8 and 16 for a TXV. Outside of this range may be an indicator of a faulty TXV, airflow, etc...
Absolute simplistic genius! I do this far few and in between that I always forget SH and SC Written on my gauges before I finished the video. Thanks for making me feel stupid!
Good job Jay! Hope Hawaii quarantine is treating you well! I heard what sounded like good advice recently regarding placement of the high side temp probe. The advice was to place the temp probe up stream “left” of the filter dryer if possible. The logic behind that advice was due to an unlikely scenario of a restriction at the dryer itself. Makes sense if charging by sub cooling I suppose as a restriction at the dryer might make the unit appear under charged. Great video and really appreciate the useful tips!
That's a great tip and it makes sense! Thank you for sharing! Quarantine is going good but unfortunately will have to do another 2 weeks on Big Island. I ll make another update video soon to report on that lol. Glad you were able to get some useful tips from the video, thanks for watching and sharing your own tips too! Next weeks video is how I add refrigerant to the unit in this video using the subcooling method. Should be interesting!
Every unit will be different so there actually is not a normal superheat or subcooling. Subcooling is usually around 12 degrees but the superheat can vary by quite a bit depending on temperatures and wet bulb.
Wow, thank you for this very interesting video. You helped me a lot 👍👍👍. Your explanations are very understandable for me. Greetings from Bavaria/Germany from a DIY HVAC amateur 👋👋
In regards to mini split heat pump units, if you are meant to use the sub cooling method as a way to check refrigerant charge because of EEV in outdoor unit, how are you able to do it if there is only 1 service port on the Suction line and nothing on the liquid line? a lot of mini split systems seem to have this set up. thanks!
got a clean and check assignment due soon, teacher gave us the choice to choose what system to check out, i never understood how to check for subcool and superheat until now, take my sub :D
Thanks man for breaking it down !! I graduated in HVAC about eight years ago and worked in the field for about three months. Never got to use those terms much, now i'm trying to keep my system in tip top shape. God Bless !!!!
I was watching another video and that dude was so confusing and then remembered this page. You make it very easy to understand. Thanks for sharing!!
How many people wrote that on their gauges
SuperHEAT is amount refrigerant vapor is heated over boiling point plus pressure. It is confusing as it takes place where things are cooling. Your mind wants to think opposite.
SubCOOLING is amount refrigerant liquid is cooled below condensing point plus pressure, once again confusing because it takes place where things are hot and your brain wants to think opposite again.
I am a master HVACR contractor with 26 years and this is the best explanation of measuring super heat and Sub cool that I have watched.
Me too
I agree this guy is amazing thanks your videos are amazing and helping me a lot thanks again keep going !!!!!!!!
You a master, yet watching a video to know how too.🤣 What you even doing here?? Haha. No need to answer. Lol
@@WildLandFarms I watch a lot of HVAC videos to stay sharp and troll people.
Mee too
2hrs of being confused in class about SH +SC and you just made it all make sense in 10min... Thanks a bunch!
agreed
Forreal though smh
I've been reading a lot of these types of comments throughout the HVAC videos and I wonder how can this be? Are all the tech schools just that bad?
Lol 7 years and still have ro look it up from time to time
Very good at explaining , can you make a video how to charge a unit and how you reach the right sub cooling and super heat ?
i am taking a HVAC class. I am so brand new in this career. Your video helps me a lot. Thanks so much.

What's the importance of sh and sc
@@WordofAdviceTV HVAC It's a cool career path! (Pardon the pun.) :) But does help a lot of people.
@@elethaainsworth5813 Superheat helps determine proper refrigerant charge. SH rule is: 1. Add charge to lower SH. 2. Remove charge to raise SH. (Partial answer, but brief) :)
