Very well explained Craig! Can’t understand why someone gives this a thumbs down. Keep up the good work! 😀👍

Okay Craig, there you go AGAIN —. Another outstanding video clearly explained. Thank you. Keep up the GREAT work!!!

Thanks for this video! I have learned more from your videos & books than I have from the year long class I took on refrigeration. This is the first time I’ve heard a coherent reason behind why superheat is taken at the compressor port. BTW... your books are amazing as well. Always look forward to your videos!

I've just finished your book for the third time . I'm halfway through trade school, I've been able to use my "stubby" analog guages and my new and shinny testo 550 to check the S.H. and S.C. on my unit , and my parents and next door neighbors as well . I appreciate your knowledge , its been helpful to try and get my " lab " work at home during these covid times ( my school shifted from on campus lab / lecture to online only . I think your book would benefit , students, apprentices and seasoned techs. Love the larger size of the print and the heavy duty glossy pages . And honestly, you so freely give away your videos and techniques that it made reaching in my wallet easy to do . Price point was very fair on the book . If you write an electrical book 📖 I will buy that as well . Thanks, stay safe and God bless

Your channel and explanations are the best I have found. My only suggestion would be to explain "why" superheated and subcooling are reversed, i.e why supercooling is pressure minus temp and superheated is temp minus pressure. Also, when the system is either overcharged or undercharged is also the reverse.

Steveo here. You are the MAN! I'll be talking to you. Hope you can help me. Steveo out wanting to learn! Help!

Thanks Craig your explanation was right on point one of the best I've heard, This video is why I subscribed to your channel... Jay

Well explained as always

WOW VERY WELL EXPLAINED! THANK YOU SO MUCH! FOR SHARING!.

I've always been taught compressor superheat method. Gaurantees your compressor isn't slugging or burning up..also gets you spot on if not near spot on for evap superheat. Of course this all depends on lineset length and how/where it's installed etc. But you explained it just like I was taught and how I think of it. Good stuff :)

Fantastic explanation,about superheat, couldn't have done better,excellent.Many thanks

Thank you for simplifyin total superheat

I hv a 3 ton heatpump txv 20 yrs old, supercool is 14F, superheat is 10F if temp taken at evap vs 13F if taken outside on vapor line, outside ambient was 94F, inside 76F, 1350 cfm on med tap measured low SP @.28 spec is .5 . My question is: Should I use the superheat of 10F using temp at evap vs higher outside vapor line? How do these sound? l believe good, Thank you, love the channel.

Amazing video!

Super heated video👍

Your the best I’m about to buy your book

Nice job and video

Doped out and replaced first txv valve after watching your videos and two other techs couldn’t figure it out so thank you and what should subcool be on a fixed orfice ?

بارك الله فيك اخي عمل رائع
