Checking the R-410A Refrigerant Charge! What to Watch Out For!

In this HVAC Training Video, I Show all the Steps for Connecting In, Air Purging, Superheat, Target Superheat, Subcooling, Determining the R-410A Refrigerant Level, Compressor Safety, and Knowing What to Look for on an Air Conditioner! Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

In school for HVAC currently. This video just made so much more sense than I could’ve imagined 2 months ago! Solid information

[jaimesanchez]

Great Job sharing some of your knowledge with your students. Keep up the great work Craig!

[SuperIcarusman]

This brings back memories of being in the HVAC school when I was younger, glad these guys are learning to get into this trade.

Hello Craig and Brian, please write a book on HVAC electricity and troubleshooting. Show us all the electrical components and the control board. I will be the first to buy your book.

As a home owner, I have a better understanding of how a properly installed system should work. I'm not a technician by any means, but due to my Navy career I know certain systems need to be monitored. I brought a new construction home with the HVAC system mismatched and undersized 10 years ago. (1990 sq ft, 2 ton compressor, 3 ton coil). The company that installed the system never responded to my questions about the AC mismatch. Knowledge is power. After reviewing a few YouTube videos, this one as well, I know I need a new HVAC system so I don't murder my compressor.

thanks very much for helping people achieve their dreams. you are impacting lives all over the globe 🌎. I am Saidu sannoh from west Africa Sierra Leone. you are My mentor.

Another good HVAC video that makes you think about what is going on inside the A/C unit. The relationship between superheat with a fixed orifice tube & subcooling with a thermal expansion valve is an important concept to understand. Our gauges & temperature probes tell us what's going on inside the unit's evaporator & condenser. This I why I continue to watch your videos, they are great educational tools/reminders.

Dear Craig, I really appreciate the time and effort that you put into accurate and excellent quality videos. I always learn so much from you. Everytime I learn something new from you, I crave to learn more. Videos are excellent because I play them over and over until I lock in on those key concepts. Thank you again from Johnsburg, Illinois.

what a privilege it be to be taught by Ty and Craig!

[scottymakerdude]

Your videos and information that you provide are priceless. You explain things very well!!! You get down to the “what” and “why”, without confusing anyone. Great job!!

[WilliamLlanes-ix]

Muy buena clase, sigo mucho sus videos por la calidad y profesionalidad a pesar de que no puedo aprovechar del todo por el idioma, gracias, thank you so much

[pana]

Excelente lo espero muy pronto este video en español.gracias

[channelname]

really good video to watch after reading through chapter 7 and working through the textbook

[nickma]

I have watched a bunch of videos just because. It is interesting the difference in approach and view on A/C with this and automotive, even though it is the same thing. In automotive (MVAC) cooling is taught, not super heat. When a liquid evaporates, it absorbs heat. That makes the air passing over the evaporator coil very cold, which is what the customer knows. In HVAC, they describe the refrigerant as absorbing heat, which it does.

I would be very interested in seeing a series on geothermal heat pumps, especially purging the ground loops and measuring how much heat is dumped or sourced from the loops and the different refrigerant charge measurement strategy.

[Iamacthepromoter]

I’m not sure if this is his ch the person that’s teaching but u do a wonderful job

[bjnopoli]

Good video. Do basically in dry climate low humidity and hot. You might want to slightly under charge your ac that has a piston. Maybe instead of 4 lbs factory charge do 3.5 lbs?

[Leon]

i've watched alot of your videos, really glad u have them, it's helped me a lot. Ps - just a constructive comment....sometimes it helps to slow down alittle, i need to digest it more as u present it.

[Honestandtruth]

As Always thank you Teacher Craig 👍👍 very informative and but this is Schooling 😅❤😂

[AngelRodriguez-qgzq]

Hi and thanks 👍🏻
Questions
10:54 If the refrigerant is in a saturated state throughout the system, does that include the compressor? If so, why isn't it damaged?
27:50 Why is the wet bulb temperature measured and not the dry bulb temperature in the evaporator? Why is WB not also measured in the condenser?
31:05 Could low superheat also mean that the equipment is oversized?
