- How to check, measure, and read superheat and subcooling on a central air conditioner unit. In this video I do not go into the details of superheat and subcooling, the science behind it and how it works. This is not a troubleshooting or diagnosing video, I simply show how to measure it and provide the simple formula needed to calculate the superheat and subcooling values.

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
@@fishlifeknives7429 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’ve been an HVAC mechanic for over 30 years and I have to say that you have the best HVAC channel on TH-cam 👍 keep up the great work.
I wrote those formulas on my gauges. I couldn't, for the life of me, keep that straight in my head. Thank you. Great tip!
I'm definitely going to do that also.
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
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!
good luck this trade has beaten me down for years if i could change i would
@@jakes8646 why?
Check out HVACR VIDEOS for some real world rooftop stuff in the desert of Southern California.
How is the job going?
Finally! A video that actually covered what it said it would, and didn't over complicate things. Thx!
Thanks for your help .
That was the first time somebody explained how to make these measurements in a way that I could understand. Thank you.
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
My teacher made this seem so complicated with all the formulas in 4 hours of class and I just learned it the best in 11 minutes of my time. Thank you!
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.
Straight forward and easy for this homeowner to comprehend...you're a gem!
This was the most helpful video out of all the HVAC videos I have watched. Thank you so much!
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💯
I don't know man why schools made it so difficult for us 😅. Thanks for the most simplified way I ever seen.
As an hvac beginner I appreciate this video for the backflip training. Subbed. Lol
Love it!
You’re a better teacher than anyone I work with.
Much appreciated.
You are a great teacher. You explain things in a very simple and straightforward way
Finally I found the good video to inform people correctly and good education thank you so much
Just started HVACR school and your video has been extremely helpful.
Thanks,
God Bless!
How is school coming
Love your stuff, brother. You break it down in such a way, that even a knucklehead like myself picks up the information quickly. Keep it up.
Your videos has convinced me to be a HVAC technician. Once I get out of school, I'm going to a trade school to become a HVAC technician.
Awesome!!! Glad I could inspire you to do that, it's a career path you won't regret! Good luck!!
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) :)
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.
not only did I learned how to read superheat and subcooling but I also now know how to do backflips, Thanks Jay
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.

No ones ever been able to explain this to me and now I finally understand
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
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
the best! always shows the best tips in plain speak!
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.
THE BEST NEWS ABOUT THIS IS, I AM A YEAR AND A HALF IN THE UNITED STATE NOW AND FANTASTICALLY 2,MONTHS OLD IN THE HVAC FIELD AS AN APPRENTICE, BEST TRADE FOR ME,
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
i am taking a HVAC class. I am so brand new in this career. Your video helps me a lot. Thanks so much.
The idea of writing on the back of the gauges is brilliant. Thank you
They make it so complicated in class that it was hard to remember. You simplifying it in a great video. They need show this in A/C schools.
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.
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 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.
But the testos 😂
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.
Best video ever to understand to find out SH & SC who want to learn
Thanks buddy for the this kind of video.
👍👍👍
That's the first time when explained it made sense, thank you.
Just started watching your videos!! Very informative and easily explained. Thank you!
This guy is awesome. Simple teaching no long story.
Special thanks on the knowledge from the Bahamas friend,you are the guy just starting classes at school on hvac
This guy is the best teacher someone can have straight to the point nothing confusing, clear as water.
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.
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.
You're welcome!! It's nice to hear that the video was easy to follow. That's always a good thing :)
Really You made it simple and easy.
Thank you Bro. Keep going
Your videos are really good and simple to understand. everyone else just confuses. i am sure I could do everything except the flips!
Thats what we need , something practical and not something with to much theory , thanks
I've learned and comprehended more from you than instructors in school
Love your videos and love your teaching… I just completed my hvac course… and got my certificate… this helps a lot…
I love this guy. He explains very simple no complicated .
THIS is an outstanding tutorial. God Bless You.
Very thankful to be able to watch your videos. Your the best man and greatly appreciate your in-to detail instructions.
Better explanation of these 2 than the instructors at school
You deserve millions subscribe , I still learning from your videos thanks again
I have a review coming up for finals and Ive had trouble understanding this but you made it extremely easy to grasp, Thank You!!
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!!
thank you man you are one of the best instructor in the industry
Another great video. This answered my question about what can be used to measure temp, where to measure and what to do with the info. Thank you for these fantastic videos.
Great video! BTW, the elegance of the simplicity for the SH & SC equations is awesome! Thanks for sharing
Great idea writing down the formulas on back of gauges.
Thank you for keeping it simple so we can understand it without any mumbo jumbo nonsense. 👍
Im in college studying this. And this video helped me alot to understand the equations much clearer. Thanks alot for the video. 👍
Excellent!!! Great video with a clear message... simple and to the point, your way to teaching really helped me out... THANK YOU!
I’m in a hvac class and we was talking about the superheat and subcooling thanks for explain it
love the videos ! just started in hvac as an apprentice and these videos are very helpful
Thank you man i have a refrigeration diagnostics certificate today this helped a lot wish me luck
you really make it easy for us to understand this. keep it up the good work man
Great video! Now I understand what is super heat and sub cooling. Thanks
You are a wonderful person.
May God bless you long life ful of peace, health and prosperity.
Your explanation is great.
Easy to follow and understand how to get the sc and sh. I love the explanation. Salute.
Like so many others have said, thanks for making it simple. Great video.
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.
Thank you for your explanations that are simple to understand.
You made this really easy to remember. I also copied and past this video for my email for future reference. Thank you.
Good video! Tell homeowner to get that galvanized pipe gas line removed!!!
Thank you so much man you'r awesome ! Every time I watch a video from you I learn a lot you are a very good teacher God bless you and all your family.
Just few minutes explanation with clear view of pracical knowledge,Ended up to clear all our doubts in one short..
Quick and Concise with tips throughout. Thank you!
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!!
Thank you! Yes, I hope to make a video like that too if I get the chance.
absolute clarity, I like you wrote the formula on back of the gauges, TY for the clarification!
Your doing good ,I'm older very older can't do the flips ,good happy for you ,I'm also reading the EPA test prep ,no experience,on chillers industrial ac ,only car ,and the old desert survival type ,I'm looking into doing some work with Walmart ,,freezers and chillers , hopefully get some knowledge,good video
just finished hvac school great video thanks usmc sgt
Hi Mr. Hvac service Technician. Great representation, intuitive, informative and actually fun to watch. Kudos to you.
Excellent presentation and you are a excellent teacher n hVe a good day 😀
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 👋👋
You're welcome! Good to hear that the video was helpful for you!
What a coincidence I’m learning SH / SC reading right now. Thanks for all the tips.
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!!!
Yah know. I always forget subcooling due to working on so many r22 systems. I like how you suggested writing it on the back of the gauges. As easy of a thought as it sounds I've never had it
Great videos! I have a r410a heat pump unit. The unit started cycling as if it had reached its set temp. First I thought the thermostat was going bad. I took my meter out and checked it out. It was showing it was still calling for cooling even though it kicked off. It had been a while since I had cleaned the coils, so I cleaned the cond and evap coils good. I then checked the schematics out. It showed it had high and low pressure switches. I figured I had a leak and it was low, so that was kicking it off to protect the compressor. The whole house came down with covid-19, so while quarantined, I didn't want to call anyone out to look at it. I ordered gauges from Amazon and thought I would at least get an idea of what was wrong. After checking, I started out at about 210 psi on both before it kicked on. It was about 70 degrees out today. It kicked on and the high side went up to about 225 psi. The low side gradually went down to about 75 psi and held there before kicking off. Definitely too low of a pressure. I will have to get someone out to find the leak and fix it. My question is... what is the pressure the switch would kick it out at on a r410a unit?
You are great at the explain about HVAC KNOWLEDGE
Tanks for being a good human and shared your knowledge
Excellent explanation, I enjoy every one of your advice. God bless you greatly.
Thank you! Glad you found the video useful. May God bless you and yours as well!
You kept it simple. Thank you.
Thank you so much for taking the time to share. And now I finally understand lol that instructions on the back of the gage is a very good idea
Collect gauge and line reading, then derive your sub-cool and super-heat numbers. Got you ! Thank for the demo. 👍🏻
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
Thanks sir I learn another lesson from you about that issue.more videos to come sir...
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.
Great clear explanation of it, keep this kind of videos coming . Great work thank you.
Thanks Jorge!! Glad you found the video useful!
I like that little cheat sheet you made there.
Thank you for making this so easy to understand.
Well done. I am in school and this helped. Thank you!
