This is the man who can teach you no matter how long you have been doing this trade. I would encourage you to not skip any of his clips no matter the topic, you will learn something. Also, if you can support him.....I would do so....best clips on the web. Thanks again Craig!
This is an amazing video. I've been a fan and follower of all your videos for quite sometime. Since I retired from the military and continued doing my job as an HVAC Technician, your videos helped prepare me for the things I didn't know from military equipment vs Residencial equipment. Thanks for sharing and please keep the videos coming.
Finally I was able to buy the book e-book, Refrigerant charging & service procedures for air conditioning 😊 i will buy step by step your another book also thanks for helpful video and motivation speech to learn Good skill HVAC Technician ❤❤❤ this is mohammad harun from doha Qatar
Not sure how this video got passed me but I just viewed it and it’s awesome! What a great tool and ability to test our own knowledge of the entire system. Thank you Craig- you really are an awesome teacher that explains everything in total detail for us that are new to the field.
@@acservicetechchannel I ordered your book btw. It’s on its way. Looking forward to learning . I Currently have my gas license but I am not registered for my ac apprenticeship. I have worked in the field though and have been looking at your UA-cam videos. It’s hard to find an employer willing to sign someone up. Do you have any advice ? I feel though with my experience and learning off of UA-cam, going back to school for an apprenticeship won’t seem as daunting.
That was fun. Nice job. Now, for the exceptions like R22 TXV on a R410a system (This has happened to me twice from factory new install AH) Also, detecting and diagnosing a mismatched split system (a Frankenstein system) would be a really cool advanced topic some time. It took me forever to finally figure out the TXV problems in the past, so it would be useful to know if I could have done it better than process of elimination. Wonky SH with SC could never check out stable. Thanks again!
Excellent video, as always. As a constructive comment, I would like to suggest that you speak a little slower. Yes, I can pause and replay as needed. But I would enjoy watching and listening without constantly replaying the last few seconds. Again, excellent videos as always. Thanks!
I noticed during the calculation at 3:07 when you had 20* of subcooling you had next to nothing for superheat. Does that mean you have too much liquid in your evap? Just ordered the book, cards, and poster set so looking forward to studying some more. Just passed the EPA with 88/100 not great but only missed 1 on core and 2 on type 3. Looking to learn as much as possible so when I go for a job soon I get paid a little extra to start.

For a new techs remember sub cooling method works only for cooling coils with a thermostatic expansion valve will not work on piston coils you have to use superheat method that coil and also remember unit has to be in the Air condition mode
That’s not correct subcooling never changes as long as the condenser coil is clean. The reason you can’t use superheat accurately with an expansion valve is because it varies depending upon the load so you’re super heat would change
When I was first introduced to R410a I was taught to take the sub cooling temp with in 12" of the metering device? Thoughts?🤔🥃 Stay safe. Retired keyboard super tech. Wear your safety glasses.
I guess that would be measuring total subcooling in case you have a long lineset, or a clogged filter drier that's rejecting some heat before it gets to the metering device. It's similar to measuring total superheat at the outdoor unit instead of right after the evaporator. Edit: Sorry, a clogged filter drier would be the opposite and act like a mini metering device absorbing heat.
You won't reach the correct subcooling or super heat with a clogged or starved evaporater right? Say someone never changed the air filter or bad liquid filter dryer

Thanks for this video now after a whole day trying to understand now I completely get the whole science behind it
PERFECTLY and CLEARLY explained! I HIGHY recommend the book. VERY easy to follow.
Wow, thank you!
Best video on UA-cam. Thank u. I got the book and it’s excellent book.
Wow, thank you!
Great video for new techs, just remember to have a spotless condenser when setting up unit
New to the field, and your videos are life saving!!!!
Thank you. Best video I've seen so far on checking HVAC refrigerant.
The best here , easy to understand .thank you .
Thank you for watching!
Amazing video. Question. What if the outdoor unit doesn’t have the sub cooling data? Most of the Goodman units don’t have that data.
This guy is the Boss!! Thank you.
Glad to help

Happy to help
Great video lots of information. With this video tutorial it’s a great tools for understanding the system thanks Craig
Glad it was helpful!
Thank you for the knowledge🙏
great information and thabks for all your help and service you provide
Our pleasure!
Excellent video
Can you empty a 410a tank into a system or is there always some left that needs to be recovered from every disposable tank?
Thank you so much for your very good information
Excellent instructions!
Wow Great job explaining!
Glad it was helpful!
What percentage of the refrigerant would be considered a “small amount” to recover? 10%? 20%?
thanks, Craig awesome presentation!!!!
Glad you liked it!
Hi great video. I only have a low suction side connection. How can i check the high side?
366psi how do you read that? I’m sorry for asking
Fabulous video, keep going with more,
Excellent. Thanks,.
Thank you, I will
danm this is just so good to listen...
So which is correct to use? Example 3: So I take it that superheat (16 degrees-high) vs sub-cooling (5 degrees-low) is at variance. This is confusing.
winter or summer
As always awesome explanation
Very simple, clear explanation. I want to add 410a to my Frigidaire 70 pt dehumidifier. What value should be on the blue side? Thanks!
Nice thanks man it couldn't be easier than this. Actually It is only if u have digital gauges
Glad it helped
Good pictorial.
Thanks sir,
Really very helpful viedo
Great video! 👍
excelent video, well explain
Glad it helped!
Thank you for a great video! I wanted to ask which method we should use if AC has electronic expansion valve? Superheat? Thank you in advance!
Literally....cool vid👍🏻
do you have a video as good as this to check the charge of the walk in cooler?
Greeting

1:12 How do you see 366 psi?
How do you do this on a mini split that only has a service port on the suction line
Look at the article I wrote on "checking the charge of a minisplit" at www.acservicetech.com/articles thanks!
what if the unit isn't running due to a possible lp or hp pressure causing compressor and condenser fan to keep turning on and off
For a new techs remember sub cooling method works only for cooling coils with a thermostatic expansion valve will not work on piston coils you have to use superheat method that coil and also remember unit has to be in the Air condition mode
Why would the metering device, change the subcooling on the condenser?
That’s not correct subcooling never changes as long as the condenser coil is clean. The reason you can’t use superheat accurately with an expansion valve is because it varies depending upon the load so you’re super heat would change
@@relentlessliving5588 because of to much or not enough Refrigant
@@boopoopies so you are saying that the Refrigant charge has nothing to do with sub cooling as long as the coil is clean
@@stuartmartin769 no I said that subcooling is used on units that have expansion valves because the superheat changes depending upon the load
What if there is no target subcool noted on tag ?
If its a single stage compressor, you can use 11 degrees of subcooling as an average. Read our full free article on subcooling acservicetech.com

Thoughts?🤔🥃
Stay safe.

I’ve heard that before also but I think it depends if it has an outdoor expansion valve don’t hold me to it lol

Question, what is the piston for r410a, 2 1/2 ton
Hey, engineer. Can I put the translation on? Me Arabic in the video and thank you very much ❤️
When Checking Temperature, would you get as near as possible to either side of the compressor?
good question, any takers?
What app do you recommend for conversion?
You won't reach the correct subcooling or super heat with a clogged or starved evaporater right? Say someone never changed the air filter or bad liquid filter dryer

Hi
I have a problem. Can you solve
How come you don’t talk about the altitude?
💯
Would the same method apply for an exv electronic expansion valve?
Look at the article I wrote on "checking the charge of a minisplit" at www.acservicetech.com/articles thanks!
Talking way too fast for me. He lost me halfway through. I’ll come back to this when I’ve had my dose of caffeine for the day.
