Please publish a book for hvac electrical! Your mini split inverter and refrigerant charging procedures material were both very good.

Already did the Esco course at the beginning of the year, doesn't seem like much will actually change....besides carrying a lot more bottles around.

Hey could you do a video on the proper way to repair an oxy acetylene hose if its leaking in the center or if one of the ends breaks off?

How does the temp glide of R454B come into play with temp/pressure measurements? Or does it? Thanks!

Great video like always How about wall mounted AC, system 2-3-4....?! Cant use this method

You have to weigh in the refrigerant charge. There's no pressures, sub-cooling, or superheat to go by.

@@acomman77 the aircon have micro leak, and need to add the gas, how you can know how much gas leak?!

What is the standard subcooling target if the number can't be found?

Great information now it’s not. going to be gas and go the customer must replace the part or fix the refrigeration leak due to. the refrigerants .

there are people already playing the gas and go game with flammable refrigerant. R290 and R600 coolers have been out for a few years already.

👍🤙🤘

Simple diags

How many of you worry about natural gas when servicing a furnace? It is extremely flammable. Do you use non-sparking tools to work around it? Dies the equipment have gas alarms? A2Ls are a whole lot safer than A2Ls. Think about it.

I have heard some techs say that 422b evaporates inside the system; is this true?? Its hard for me to believe this as refrigeran don’t anywhere unless theres leak. Thanks in advance

What do you mean? It "evaporates" as in turns into a vapor in the evaporator, but it doesnt just disappear and go away. It goes back to the condenser to recondense into liquid

@@MsckMatt sorry, i should of been a bit more clear. I know what happens inside the system with change of state on the refrigerant. What they mean is that they have come to a unit and its just air in the system where previously 422b was used.

Checking sub cooling method is the same for any refrigerant type in the system. So why a specific video for 2 specific refrigerants ? Just watch one of your previous videos

Because there's probably people terrified of these new style of refrigerants. I've seen people asking how they search for leaks on them when you only need to know the type of classification it has like HFO or anything like that to know what detectors are compatible. People are just way over thinking the refrigerants I believe.

So what's the problem for him, to do a specific video if you don't wanna watch don't watch it.

Isn’t it if you have a piston it’s super heat & if it’s a TXV it’s super cooling?!

@codystrasburg2644

Yes that's how you charge but the other tells you what is happening in the system, you can have a txv with 10 degree subcool but super heat of 22 plus and know there is problems with your system

Yup, of course we still have to recover these A2L refrigerants also. Let's make sure all of us have now explosion proof recovery machines and vacuum pumps 😮

Those types of refrigerants are not as flammable as you think they are. Plus all refrigerant oils can catch fire if you braze with oils still in the line

@@sprockkets seriously tho they don't realize that all refrigerants are explosive if you apply enough heat and compression.

So basically no charging difference than with any other refrigerant besides probably a worse idea now to smoke while charging? Don't forget what is caused by dirty or damaged coils and outdoor + indoor temps.. Also with having to know about proper airflow.. Curious to know if flammable vapor refrigerant sensors will also sound an alarm like a smoke/ CO detector besides shut outdoor unit down and force fan operating to dilute flammable refrigerant vapors inside of conditioned space? Maybe put som aux contact connections on them to open any window that can open or close by a switch also!? Absolutely should in my opinion to wake more people of informing them what more nonsense is going on in our country :( Prices of new HVAC equipment running these flammable refrigerants is expected to increase by another whopping 30%!! + an extra two cans of refrigerants us service people will have to keep in or maybe on our trucks!?? **Great also new way to scare customers of when they have a leak on thier system. Fix leak, replace system, we have to disable unit if we know there is a leak so we're not liable if there is a refrigerant gas explosion in your home! Not just one but 2 different ones coming out depending on which one suits$$ each manufacturer the best. Not backwards compatible with 410a equipment, even 410a evaporator coils that could run R-22! Nope. How can we prepare our customers more of knowing of how much more expensive because of government HVACR equipment/ service/ installation/ replacement will cost them?? About SH ans SC. Great to know which # on PT chart to use. All them should show liq and vapor instead of more confusing dew and bubble. Utube videos showing how benign or hard it is to light these A2Ls is completely misleading propaganda! Homes and buildings in Europe explode because of! Can we change this!?

Judging by your writing skills you are incapable of being an a/c tech.

This video seems useless. Same practices with all refrigerants. Use PT charts, check temperature, and check pressure to see if properly charged or other issues.

Chill out. Craig has taught so many technicians and has contributed to our industry more than you ever will in your lifetime. Some people just entering the industry need the basics. How inconsiderate of you. You didn’t need to comment at all. Next time keep your thoughts to yourself.
