His book is a masterpiece....highly recommend. I have it along with his cards and workbook. I'm not a professional HVAC tech although have done my own work for over 30 years on my systems and those of my family, friends, etc. The book is a must have resource.
This is my favorite channel, He explains very well, and in detail, great tips from a real professional and lots of good information, Thank you very much.
Great videos and very good book, which I am still reading ! You mention in this video to wear your Nitrile gloves. I had thought, that for refrigerant Butyl was necessary. Can you please clarify?
A valve core depressor tool is great for the high side as mentioned. Instead of a standard T on the low side as mentioned, how about a core depressor WITH an additional tee'd-in 1/4" fitting in case refrigerant needs to be added? So, there would be two 1/4" fittings instead of only one going to the gauge. That way, you could have a core depressor tool with gauges on both high and low side while still being able to add refrigerant to the low side if necessary. Is there such a fitting made for the low side?
I found the Yellow Jacket 49138 3-1/8" Blue Compound, 30", 0-350 psi, R-22/404A/410A Gauge Degrees on the tool list, Can you produce a video about setting them up wth the low loss fittings? Thanks.
At 6:02 you say to use valve core depressor tool WITH A BACKSEAT on the high side. Why not just use a standard core depressor WITHOUT backseat feature. I don't see the purpose of using the backseat style depressor in this application. Am I missing something?
Ma Ma, I was likely refering to when using a hose, not a quick connect test gauge/probe. This way you have a controlled release of what is left in the hose or an ability to charge the liquid left in the red hose back into the system. As always, thanks!
@@acservicetechchannel Craig, thank you for the clarification. That set-up you show in Tip 10 with the two test gauges is a great way for new techs to get started without spending on expensive digital gauges from the outset. Maybe I'll ditch my digitals with hoses. Hmmmm
Last week hooked up my gauges to a HP in a condo. The system was a little low but cooling. After purging the lines and adding 1LB of gas and waiting a few seconds, the high side went up to 470-500ish. Then back down to 330ish only to go back up. Shut the system down and tried to figure out what went wrong. I must not have purged the lines good enough. Had to do a full recovery, vacuum and new charge. Wasted a lot of time but at least the system is cooling a lot better than before and the customer was happy. I should have just left the thing alone. Many techs have been telling me to stop shooting for high Delta T and 15' your good you don't need a 20'. Mind you its south FL and that's what we shoot for. I don't know what the standard is for other parts of the country
There is no such standards for delta t no matter where you live. Just a heads up, airflow and indoor wetbulb / rh% determine delta t, even outdoor drybulb has an effect on it to an extent
No. You’re not going to add condensate water to the system when attaching a temp probe to the suction side because it’s still positive pressure in relation to atmospheric pressure.
Temp probe? Do you mean pressure probe? The probe depresses the Schrader core, so things are free to move about. Connecting to the low side service port quickly after removing the cap is a great idea.
@Matthew Ahrens it would be called a pressure probe that you would be hooking up and there's absolutely a very good chance of introducing water to system. That's why when I hook up I screw probes on slow to blow out the ambient air from inside the probes fitting by letting the refrigerant purge it out for just a second is all is needed. But it likely won't blow out all the condensate and that will end up in the compressor/oil no doubt. So he has a good point here,one that nobody really thinks about or practices I might add. The suction pressure being higher than atmospheric pressure will not prevent that water/air from entering the system. It will be sucked rite in by venturi effect basicly by the flow rate of the vapor passing by the port. Think about it. It's what happens
@@HVACRTECH-83 why is that? seems more efficient and no more unnecessary mistakes, contaminants or refrigerant loss opening these service ports just to measure pressure

This channel is awesome. He always explains things very well, and in detail. Thank you!!!

reference cards I got are a year old in the field and still going strong! Great stuf
Sweet! Thanks!
Very good sound quality in your video. Good content.
The best information from someone but the tools is what falling me
This is my favorite channel, He explains very well, and in detail, great tips from a real professional and lots of good information, Thank you very much.
Thank you for these amazing videos
Great information, and video
thanks, Craig for sharing love all your work man.
Thank You ! Excelent video

Where can I purchase the charging tee you used in this video?
Another great video, Thanks!

Great tips. Thank you for your video!!!!
Any links to the single gauges with the T instead of the manifold?

With the hoses that have the shut off how do you remove the air between the screw fitting and the shut off valve?
Nice. nice, nice!!!!!
Always appreciate it Ma Ma!

I don’t see a link for that t valve
Good stuff. I learned a few things. Is anyone still using anything other than digital probes?
Yes, New York State won’t buy me updated equipment lol
Thank you i'm from indonesia

Tip number one. Make sure you are properly trained and Licensed before doing any of these.
Tienen el libro en español?
This T is a core remover?
What's the disconnect procedure?
No. You’re not going to add condensate water to the system when attaching a temp probe to the suction side because it’s still positive pressure in relation to atmospheric pressure.
It will go in your hose... And when you add refrigerant to the unit through the same hose... Water goes into the system
@@jessestewart3835 if you purge the hoses like you’re supposed to whenever you connect to a system it will remove any water.
@@charlesastaley no it won't

Where's a good place to find these valve core depressing "T's" that have a backseat??
👍
why don't they save us time and have built in pressure gauges for these systems.
That's coming soon
I wouldn't use them if they did have them.
