You my friend, are going down as one of the best HVAC teachers ever 👏🏼👏🏼
-
I've heard that " clicking sound " so many times when starting up a newly installed minisplit but never knew that is was the metering device. These videos really give me an edge in the field.
-
I feel like I’m back in college studying electronics technology but with more hands on training. You would make a great professor at a university sir. Thanks for the free college classes. 👍
-
This is by far one of the best EEV/EXV classes I've ever seen.....such great information, love the cutaway. Thanks for the video.
-
outdone yourself....I bought your manuals out of respect, going to gift my apprentice because real recognizes real and I cant explain like this...amazing job my friend
-
this really helped me during replacement of 2.5hp LG compressor, i had to remove the EEV to create space after the workdone i fixed the EEV clockwise direction and the system couldn't discharge refrigerant i came across this content that helped me understood the magnetic force and i clipped the EEV in anticlockwise direction and it worked 💪 ❤❤❤ really grateful 🙏
-
Craig, your videos always stand out in content and clarity, many thanks for a new value
-
As design and commissioning engineers, we rarely pay enough attention to these details - so I appreciate your detailed work here.
-
This is the video I have been looking for for so long.
-
Fascinating... This explains the "rattle" on the old FloTronic EXV (Carrier) at start up when it drives closed for pump-out at start up. Same operation as these, just bigger. Glad you made this video!
-
Absolutely fantastic tutorial on the operation and how it actually works. Bravo Craig
-
Thank you! I was going to buy a $200 eev magnet tool but now i know all i need is an eev coil head! 🌟
-
This is great, had issues with them but it ended up being a faulty board. So helpful to see the guts in action
-
You make it easy to understand with your flawless explanation. God bless you.
-
I’m impressed dude. I wish I had more instructors like you and tech school. Although mine were pretty good down in Lawrence County Georgia- Gwinnett Tech. During initialization, I think it only seats it in one direction. The manufacturer knows how many pulses it takes to get to the other end.
-
Thank you so much for making this video! This really helped me to understand how the EEV works and how to troubleshoot them.
-
Excelent video. The best decription of function and principle EEV. Big thumbs up !!!
-
Fantastic video from one of the greatest teachers of all time!
-
Best Expansion Valve Video I have seen ! Amazing Detail ! Salute !
