Thanks for that explanation!! I have always done New construction residential installs, but am trying to make the switch to service and changeouts, and so many HVAC guys online overcomplicate everything and make it all seem like rocket science instead of breaking it down in laymans terms. Im thinking of doing my own business too and its essential that I learn the ins and outs of charging units, superheat/supercool etc. SUBSCRIBED
He didn’t say what type of metering device is being used. Because he’s measuring SH I’ll assume it’s fixed metering, and with fixed metering a wet bulb temperature is an absolute must.
Thank you so much for video. Can the accuracy of the refrigerant amount be determined by only monitoring the superheat value? If so, what is the appropriate superheat value for R22? (Fixed, capillary tube minisplit unit. Not TXV) Thank you.
It can help but you have to read the information off the nameplate/literature inside the cabinet. It should show charts of what that system is designed for with a + or - for the superheat and depends on the length of the line set.
You can check any thermometer or thermocouple in an ice bath. That's completely common. You can put a few together and check them. Then you can calibrate one or several. You can check them in a warm or hot bath or boiling. You can check your barometer and use a correction chart for boiling distilled water. Then you can check your pressure gages for a zero and low against high through a range of pressures or against a standard or against your refrigerant of choice as long as you can measure the temperature correctly.... You see, there's always error in measurement. The question is how much error and how to minimize. Inexpensive tools can be plenty accurate. Technique and knowledge will bring in great results. Understand the scientific principals and maintain your equipment. You can do great work even in adverse environments.
Did U check with super heat because it doesn’t have a expansion valve …I’m new to service getting ready to start school trying to soak up some knowledge
@@user-jr5ru3sj2q knowing how to measure superheat and subcooling is important in our field. These numbers help us better understand how the system is running and what adjustments we need to make so that it is running at its best.
One month of school right here boys
The simplest methods are always the best. Best explanation I've ever seen. Thank you!
Simple and comprehensive.

Thank you for subscribing and best of luck to you on your new chapter! You got this!! 🙏
Perfect explanation easy to understand. Thanks
Subscribed keep em coming
Excellent work 👏
Thank you!
Awesome 😊
Thanks easy easy
Pretty thick to have that written down behind gauge
Superheat it’s moving target!!! Need temperature indoor close of the return and outside temperature and calculate
the line leaving the evap and before entering the compressor
@@jgabriel1625no he’s talking about wet bulb and dry bulb

Clean that circuit cabinet!! Good God! 😮
And the target super heat?
Saving video...thanks man
Yes sir
Thank you so much for video.

This tells how to measure. There is a formula to determine what it should be.
Great video thanks where did you get that clamp ?
I got it at a local HVAC supply house. The brand is Hilmar you can find them online and this one can be used with a field piece meter.
We all like a green clamp idk. Green it ll never get lost.. tnk you. 120 psi great for 410 A
This is on winter or cooling ?
This was during summer, so cooling
-13
that is a 410 System... why are you even looking at Superheat ? whats your Subcooling ?
I made another video on how to find SubCooling. Just showing new techs how to get both.
He said superheat due to piston and not a tXV.
Using SH or SC is determined by the metering device not the refrigerant
throw away yellow jacket gauges, a mickey mouse feildpeice clamp meter, and a Hilmor clamp thermometer. wow what a combination.
Maybe give a suggestion instead of just whatever information you just gave.
Lol you good bro?
For what it's worth
This guy can figure it out old school
You need to be able to do it with this method then graduate to the new fancy guages

Yes that’s correct! Good luck in school!
@@DavidandgoliathhvacAlso new, why would this be the route to go?
