Thank you I’ve been doing this for 5 years but I forget this too it was taught to us in class and it seems it stayed in class…
Just to put it out there each hose is about 3oz of refrigerant so every time the hoses are connected you lose about half a pound .......this tip is awesome
If system is " critical charge" do not do this just vent to atmosphere. But on larger systems i do this everytime. It is not about "saving" refrigerant but not losing those oz's out of your hosing and dumping out of your hoses. This guy is on the right track and people talking shit are def from gen z not knowing what the og's have lost on the past! Got taught this 18+ years ago. And def want to do this in 410 so you dont burn your precious fingure prints off your delicate fingures off!
A critically charged system is one that requires a very precise amount of refrigerant. Wouldn’t it be more important to ensure you don’t lost refrigerant on those than a larger system where a few ounces doesn’t change much?
@@Practicing_HVACRThe only reason I think he said he was against it, is because the hose has its own weight/pressure of refrigerant beyond the scale and might add a couple OZs more than necessary… but not really sure😅
Don't forget to bleed the recovery line....there could be air in there that you just let in the system.
no, because they are individually isolated on the manifold
Another benefit to ball valves is these cause less of a restriction when you’re pulling a vacuum or recovering so it goes faster.
I have them and never knew that that's pretty good to know.
That shit gonna be an ice cube after a few days
Omg I had no idea, thank you so much
If your fast enough with a refrigeration wrench, you can pump down the system to about 50 psig & then close off your hoses.
you also let the oil and other shit that is in your hoses back into the system. personally I haven't seen it effect a system but shit you never know and I know it can't be good for the filter drier or txv
Can i do that with normal low loss?
Good shit
Lol, that's good habbits. I've been doing that for 15 years. Have you guys just been releasing it?
What set is that?
Nosso sonho aqui no Brasil,mas se chegar aqui vai ser em torno de 8mil reais 😂😂😂
Blowbacks are better I think
how do you feel about the job link
They don’t last long and they’re a pain to repair
Damn this thing low😂
Is there a proper way to connect? I've been made fun of for not purging my hoses upon connection
in my opinion if all you're doing is checking pressure (not adding or recovering) there shouldn't be any need to purge after connecting, now in order to save refrigerant you're affectively "adding" because you're taking refrigerant form the closed off liquid line and adding it back to the system on the vapor side yes you should purge air out of the top of the lines. Since hose valves are usually left open after disconnecting air will get in and fill it, now when you get to a system and connect the hoses, that air is still in the hose as refrigerant enters to take a pressure reading, definitely don't want to add that into the system. Maybe a good practice would be always purging the air out just so you're in the hobbit of doing it so one day you don't forget and add any air to the system. Thank you for the question Nicholas!
Cant possibly get accurate reads with Air in your gauges. Air is made of nitrogen,oxygen,co2 and h20. Any of this mixed with refrigerants will give an inaccurate reading. Saying it does not matter is like saying non condensables wont effect how a unit runs.
@@WhowereEpsteinsclients air won’t change your pressure reading
Connecting technically your suppose to pump it down til the contactor opens
😂😂😂😂😂😂 BS BS
You’ll never be a technician
Nah I like spraying it in the air like I’m in a fast and furious car. PSHHHHHHHHH PSHHHHHHH (osha watching me through bushes like “look boys we got ourselves another one”)
Let's do this 🫠 me in the heat 🫠
Dude really said “how I save refrigerant” boi you say it like you’re the only one doing it like this. This simple thing is taught in every single college or institute when you’re learning how to put on and take off your gauges in a system.
