Absolutely the best of the best. I fly small airplanes and now I’m on the first week of air conditioning, of a total of 10 week full and intense program, class training. I rarely found good videos on aviation training, and same thing now on air conditioning! Clearly Craig Migliaccio is the best of the best . I will become a good certified technician because of people like him . Thank you 👍
On his first 4-port manifold example he put the vacuum gauge right on the manifold, but you can put it on your valve core removal tool, just like you were pulling a vacuum the way he recommends. Once you valve-out your manifold and hoses, it will behave no differently than not using a manifold. I like pulling through the manifold because you can just connect everything up once, then pressure test, pull vacuum, then adjust refrigerant.
Once again I appreciate your detailed explanation on the differences between the methods to use. I personally agree that staying away from hoses when possible is awesome and Less lose of refrigerant and cross contamination going from system to system.
Thank you for all your great information that teaching us here. I really enjoy watching your awesome videos. You are so knowledgeable. Learned a lot from you sir. Appreciate it.🙏🙏
I like 4-port Digital as I work on Self Contained Unit Ventilators and the like. I can hook the service line to the refrigerant tank and pull a vacuum on the hose right up to the tank alleviating the need to air purge at all. Additionally I have also used the service line to hook to other locations (liquid line, outdoor suction line (HP), receiver etc). to aid in faster evacuation. I respect your reasons for not liking them, I just think there is a use for them depending on your job types.
Always appreciate. It really does depend on what your usual situation is. I do multi family apt complex a/c maintenance and it’s easier for me to just use gauges with everything is one unit, instead of several pieces to keep track of. But yes, I can see the advantage of remote probes in a few situations expensive- so I guy needs to really think about whether he needs the cool - tool. 😁 Thanks man.
Makes you wonder why those long refrigerant hoses are sold in the first place, or advertised as much as they are. That 60 inches (5 ft.) hose must hold a lot of liquid refrigerant. Imagine all that refrigerant vented into the atmosphere because a rookie tech did not charge it back into the system before disconnecting the hoses? I am sure glad you emphasized this in your video.
Thank you for giving me confidence to continue been the only non-gauges technician in all of the places I have worked. It seems so obvious the benefits of Bluetooth gauges, I carry 2 on my tool bag always, they are so small. I don’t need no dam subcooling readings all the time either, the sman3 and all those wires you have to carry. Subcooling is for charging, you can just look at pressures and find air flow issues that fixes subcooling. I carry those exact T’s you were talking about in my field pice tool bag that has the psychrometer and temp probes.
@@craigerickson8712 I will check my T next time I use it and see if there are any numbers. Someone gave me this T and I added a shredder valve to the charging side.
Great detailed video as always! I use compound manifold gauges as of right now. Looking to get fieldpiece probes soon. I like the idea of getting rid of hoses. And think it will come in handy doing super heat and getting an active wet bulb sent to my phone while I charge. I definitely will get that core depresser tool!
Great video, 14:45 is what they had us do in school and at my job. I like the probes but I already own the 4 port smans. I will be starting to the 2 hose vacuum setup.
No techs at my company uses digital gauges. Im 25, been doing this for 6 years, and I still prefer the OG. I got a single digital stubby gauge for quick hook up but that’s it. the The price for s-man is crazy
Craig, Great info. I am still on the compound gauges and just need the right nudge to go digital/wi-fi. I just have concerns about reliability. How many times can you drop them or get beat around in a truck full of heavy tools. My YJ 41's are more than 10 years old and still reliable as the day I put them in service. Do you have any manuals on installs? Looks like you have a very comprehensive book on service. But what about installs? Same issue I have with trade schools. The most important part of the system is the installation, but no one is training the young folks on it. What a shame. But I guess it will keep the service techs busy correcting poor installations.
Not that i am aware of. I just like the ability to have the digital display and wireless. I would think that Measurequick would incorporporate other manufacturers at some point. Thanks Ty!
Hi I am learning a lot from watching your videos.I need some advice. My ac r410a system keeps running low on refrigeration about a few days after being fully charged.and every time I turn my ac on my high side lines freezes for a few minutes. Have checked to see if I have a leak haven't found any.I am learning about refrigeration level one so far.I have tried to fix this problem many times but still nothing is working out.can u please advice me on what is causing this and where am I going wrong?
Most common leaks for piping parts and compressors are braze joints & fittings, on coils if not a leak from corrosion, then typically braze joints at the hair pins. or vibration wear through of the copper tubing against the end plates (steel plates at the end of the coil that hold the copper tubes in place on fin & tube type coils, but that is much less common than corrosion). you really need a good leak detector if you have a small leak...or several big bottles of viper "big blue" and slowly coat every joint, fitting etc. best of luck...some can be very "fun" to find.

What part number are those " T's " ? I Would like to add those to my small lolli pop guages

$100.00 bucks for mine. I use Testo for A/C checks and Fieldpiece for diagnostics, repairs and commissioning.
More accurate and don't fail all refer guys use analog
Digital batteries dies and u never know if they failed
Almost to 300k subs.....that is quite impressive
Thank you very much Jason! It is quite unbelievable to me!
Great info. Thanks Craig.
Awesome video!
Thanks a lot Joe Tech!
When you recover refrigerant do you close the king Valves.

Does the Refco set work with Measurquick?
Not that i am aware of. I just like the ability to have the digital display and wireless. I would think that Measurequick would incorporporate other manufacturers at some point. Thanks Ty!
Will all of this wireless probes work with the new refrigerants.
What's the best book to started with
What kind of pump is it on the video ?
Can you use any thermocouple?
I thought another feature of some of the 4 valve manifolds was something to do with liquid charging.
Great infor
What brand of valve core depressor tools do you recommend
Appion seem to work very well, thanks!
@@acservicetechchannel can I ask where you got them at I currently run c and d but they don’t back seat and hold gas in my hoses
