How to Read SUPERHEAT and SUBCOOLING

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!!

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.

[lauderdalechad]

2hrs of being confused in class about SH +SC and you just made it all make sense in 10min... Thanks a bunch!

[hoado]

i am taking a HVAC class. I am so brand new in this career. Your video helps me a lot. Thanks so much.

[vernroach]

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.

[freddygill]

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!

[donovanslezak]

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!

[Weztcoastguy]

I’ve been an HVAC mechanic for over 30 years and I have to say that you have the best HVAC channel on YouTube 👍 keep up the great work.

[basspig]

That was the first time somebody explained how to make these measurements in a way that I could understand. Thank you.

[martinmyers]

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

[skol]

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👍🏻

[marcelinovelez]

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!

[imhungry]

Finally! A video that actually covered what it said it would, and didn't over complicate things. Thx!

[judetimngumloh]

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,

[renenunez]

Straight forward and easy for this homeowner to comprehend...you're a gem!

[stephenflaim]

The idea of writing on the back of the gauges is brilliant. Thank you

[guitarplayert]

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.
