Love your vids, but I question your technique attaching lines to the system. The high pressure test line should be connected when the system is OFF, the low pressure test line should be connected when the system is ON. Puron costs us consumers 50 dollars a pound. My last tech vented enough 410A to really piss me off (and then claimed I needed to pay for a puron charge).

[@charlieb8417]

if suspected low refrigerant should you check with bubble Leak Detector even before removing caps? and then again after removing caps before attaching gauges? isn't the schrader valve the most prevalent cause of slow to very slow refrigerant leaking?

[@tom20152]

You should connect a little stubby hose (6" or 12") between the gauge manifold and the Kwik Charge on the low side to put less strain on that 1/4" male flare. Would make it easier to handle as well.

[@acservicetechchannel]

Thanks

[@user-bj4lp3fr1o]

Can you take the yellow hose off the manifold and add a cap to the manifold where the yellow hose originally connected? That would avoid having air or refrigerant in the yellow line.

[@mon0theist_tv]

What's that thing connected to your blue hose on the manifold? Oh nvm you answered that 😉

[@HowToDoitright]

Hi great video. Question. What if subcooling is low and you add 410a and the head pressure increases but your liquid line temperature also increases? This way you will never reach the proper subcooling (txv system). What’s that indicating?

[@derekwagstaff9279]

Ensure proper airflow and no refrigerant restrictions before getting your target anything

[@gojooyoung]

So did you basically return all trapped liquid refrigerant trapped in the connector to the vapour side?

[@piezomotor]

Hello, thank you for this video. I have a question - my R22 bottle has the red and the blue valves but my R22 manifold has the yellow input house. Do you know by any chance where I connect the yellow house, to the red or the blue valves?

[@MichaelREFLECTS]

@acservicetech are you running the AC while disconnecting? Wouldn't that shoot out refrigerant from the liquid line (higher pressure) to the environment? Also what do you do if when you disconnect a liquid line with the system off - a lot of refrigerant shoots out?

[@acservicetechchannel]

Yes you could wait five minutes for the unit the equalize and then disconnect the red but if you are doing the disconnect process then you would be loosing much less refrigerant anyway since you are charging refrigerant from the red back into the blue after disconnecting, thanks

[@scottm3552]

I noticed you didn't purge the liquid hose upon connection. Could that of caused a different pressure reading? 2. If i wanted to add refrigerant using the low side if i was using r410a, I would put the kwik charge device directly on the refrigerant tank upside down; while the liquid valve on the gauge was closed. correct?

[@mark.r8900]

Hi, what if the saturation temp on the low side is around 20F. And adding more refrigerant only increase the subcooling. Could this be a bad txv? Thanks

[@phillipborbon2059]

I've been taught differently in school, we charge with the high side, and recover on the low.

[@acservicetechchannel]

The only way you would do that is if the system was off and you were breaking the vacuum with liquid refrigerant into the empty and vacuumed liquid line. You can recover by pulling from both sides while the unit is off. In this video the system was running so refrigerant would need to be added into the low pressure side slowly, thanks!

[@ATH24TXEX]

Question for you Craig (or any other techs who can chime in) about that Imperial 535-C Kwik Charge: I just bought one off Amazon and the label on mine is pointing the opposite way. The "Flow" direction points from the male threaded end toward the female end (just opposite of yours and all the others I've seen online). Bought it brand new in sealed package, so it has not been tampered with. Not sure if the label is just backwards or if perhaps the end caps are flipped around, as I know they can be swapped side to side. When I blow low pressure air through it from the female side toward the male threaded end, no air passes through it... when I apply the same low pressure air in the opposte direction, from the male threaded end toward the female end, the air passes through it freely. Which way is correct? Trying to determine if the label was just put on wrong or if these end caps are on the wrong ends. First time using this particular item, so I'm trying to make sure mine us set up correctly, as something obviously isn't right with it as is. Really appreciate your videos, btw... they are superbly done.

[@ronaldcach2779]

Hi, what do you do with the refrigerant left in your gauge set lines? THANKS FRIEND

[@acservicetechchannel]

Look up acservicetech disconnect procedure. I show this with 3 position valves and schrader valves. Basically you charge the liquid back into the vapor side after disconnecting the liquid gauge so the amount that is left in the gauges is only a very small amount of vapor. That would be de minimis. Thanks Ronald!

Hi: Love all your videos. One question though. At the end of the disconnect procedure there is still some pressure in the gauge set. What are you SUPPOSED to do with that residual pressure??? I know that it can’t stay there. Keep your book inside my AC tool kit. Thanks again !!!!

[@Froggability]

Paul Rozinski . Release..

[@dirtydan678]

De Minimus, just let it go to the winds

[@mhdzakimlr7573]

Mate, technically there is remaining gas in side the manifold gauge after he turn off the fittings connector at both yellow red hose and plug off both of it. To make it's empty, blue hose need to be remain attached to the compressor unit and during this process, the compressor unit need to remain on, so the balance gas inside the manifold gauge and hoses will be suck to the compressor unit automatically. Reading at the manifold gauge is still active because there was a pressure suction caused by the compressor unit while it's running.

[@grzegorzewskim]

I had noticed there were pressures still left in each gauge, what would be the proper way to bring both gauges back to no pressure?

[@parkerpasternack206]

The refrigerant that is left in the gauges is ok to release. It is called De minimis release and EPA allows it

[@kennethyaker3820]

appreciate VDO, I went to hook up gauges but found that on vapor line there was a valve so ok!!!!!!!!!! BUT on liquid line there is a a valve inside which takes an allen key. PLEASE ADVISE

[@acservicetechchannel]

Does the port have a schrader valve? Typically the valves with the allen key are not king valves and do have a schrader attached in the 1/4 connection for the hose. It is the square stems that are king valves which require mid seating to get refrigerant from the line valve to the 1/4" connection port -- kzbin.info/www/bejne/m4nOooKJlNasrdE -- kzbin.info/www/bejne/j5XYYXVplLyeqdU

Love the videos. Question, when you bled the yellow line was that from the front of the gauge set or the rear. If it was from the front side it seems that the yellow hose was left with air in the line. I would assume that you would bled from the backside so the whole yellow line is bled. Did I miss something?

Yes you should bleed the air from the other end of the yellow hose where the valve is attached to the hose, thanks

[@jcstudios5629]

Number 1. What's with you AC guys always using bubbly to check leaks? I bought a wand style Freon detector for $21 off Amazon and it works great and I'm not an AC guy. 2. Great demo, but you're using hoses with cut off valves on the end, which explains why you didn't purge the lines when you hooked them up? 3. Back to number 2, if your hoses don't have valves on them, you have to first hook them up with the system off so the suction line doesn't suck in air on the blue line using no cut off valve hoses, next purge out the air, then turn on the system, correct?

[@HowToDoitright]

Can I use the same hoses and gauge for R22 if I have used it for 410a in the past or vice versa ?

[@acservicetechchannel]

Most of us have 2 to 3 sets in the truck, one for each refrigerant we mainly work with due to the oil but yes it can be done if you are starting out and only have one set. You can also blow them out with nitrogen to rid any excess oil in the hoses, thanks

[@ronaldcach2779]

Hi, I noticed you left pressure on your gauges, after you disconnected them. Do you leave that refrigerant in your gauges? Or do you bleed them off, before you connect to the next unit. THANKS FRIEND Great video

[@acservicetechchannel]

This video shows weighing in liquid into a vacuumed system. - kzbin.info/www/bejne/pJTKfXePp9uBbNk - You can't add refrigerant into a system that is off with refrigerant already in it. The sat pressure in the bottle will be the same as the saturated pressure in the system. Some people just meter the liquid in extra slowly by the handle instead of with the kwik charge 535-c. I love that kwik charge but it can be done slower without it. Thanks Michael Kokoschka!

[@tonymoran9794]

Should the unit be on or off when connecting or disconnecting? Does it matter? I recently put my gauges on a 410A system and I guess I had a lot of pressure built up and it blew the gasket off the hose when I disconnected it and lost a bit of refrigerant too. I probably didn't take the hose off correctly also. (only the 2nd time I hooked up hoses.)

That is awesome to hear! I would start off by trying to get a less expensive training such as a county technical high school that does Adult evening classes at night and trying to get your foot in the door at a local company, if possible, thanks

[@litewavve]

Sorry I am missing something. How do you determine when to stop charging? You took off the liquid line during charging, and never put it back to confirm the if the super cooling temperature has reached. So how did you know by the vapor gauge alone?

[@acservicetechchannel]

The reason is because in this video I did not add any refrigerant but only checked the charge and then put the liquid back in. If you were adding liquid refrigerant then I would have a full yellow service line too and could accidentally overcharge if I stopped charging right at the correct subcooling and then performed the disconnect procedure. Thanks!

[@litewavve]

Oh, that's right. The yellow line connected to nothing. I was thinking you were recharging the system. It now makes perfect sense to me. Thanks.

[@Alberto-by7zq]

When adding refrigerant from the hoses to the unit, do you have to do anything different if your hoses don't have those shutting valve at the end?

[@acservicetechchannel]

It is more about loosing a lot of refrigerant when disconnecting more than anything else. You could purchase valve connectors for the end of the hoses. I have them linked here- amazon.com/shop/acservicetech , thanks

[@Alberto-by7zq]

Awesome, that was a quick response, thank you! On another issue, I connected my brand new YJ set to my unit (410a w/interior TXV) in order to find subcooling (9 degree per unit label). My high side gauge went all the way up to 250 psi where it settled. However, my low side gauge didn't move a bit from 0. Also, saturated temp was 2 degrees above temp of high side line. Not sure how to proceed, I disconnected the lines. Should I ignore the no pressure on high end gauge and the temp differences and add a little refrigerant to see how the unit reacts to it? Everything else is working properly, but the air coming out of the registers is not cool. Texas heat is already in the mid nineties, yikes! Thank you!

[@vgbr88]

Your videos are great! Is it okay to keep the leftover refrigerant in the manifold hoses to reduce air contamination the next time you connect the gauges to a unit, or does that put too much stress on the hoses over time; also, is it a good idea to pull a vacuum on the hoses before connecting them to reduce air contamination. Thanks.

[@acservicetechchannel]

Those ideas are both good but epa 608 does not give any other guidance than that you can't move refrigerant from one system with a certain owner into to another system with a different owner. I would still perform the disconnect procedure but when I work on two or three systems at one house that are the same age and shape then I do just leave the vapor in so I don't have to purge again at that location, thanks

[@WayneKellen]

My system does not have a TXV in it. It is listed as a "flowrater" system. What is the process for checking this type of R410a system?

[@acservicetechchannel]

That is a piston metering device. Look up "acservicetech superheat playlist" feel free to ask questions after if questions are not fully answered, thanks

[@MrHefat]

Thank you for the great video, I am installing a duo split system, to check the subcooling do both inside units have to be switched on ?

[@acservicetechchannel]

Yes systems with a txv in front of the evap need to be on at both the inside and outdoor units with proper airflow. This process is correct for single speed and two speed compressors. Thanks

[@joseorta9928]

Hi Ac, I am getting ready to connect to my first unit since leaving college, I have a Testo 570 gauge set and I have just got one of the imperial vaporisers that you recommend, can I connect one of the probes to the liquid line to get an automatic Sub cooling measurement ? , I suspect something is wrong with this walk in freezer as the suction line valve outside keeps icing up badly, there is ice on the evaporator coil inside and lot of fins bashed in, fans seem to be working, whoever fitted the units though has put no fall on the drain pipes and outside the outlet is bone dry, any advice would be gratefully received

[@acservicetechchannel]

Depending on the temp the freezer is supposed to run at, it may have or need a defrost function. This can be electrical or part of the refrigeration circuit in the form of a hot gas bypass. You don't want to check a charge while the system is frozen. Is there too much product to move to defrost the freezer? I don't have many videos on refrigeration but mainly air conditioners, heat pumps, gas furnaces.

[@jiangbian76]

Great video! I am learning HVAC by myself and I find your videos very helpful. questions: Is the compressor running when you try to charge the liquid Freon to the suction line? I guess it has to be, but just can't hear any noise in video. How much Freon you gonna lose if you don't charge the liquid back to the unit? When you purge the yellow hose, how do you know the air is completely out? Thank you!

[@acservicetechchannel]

The compressor is running but my mic cancels out the background noise. The best way to disconnect is to anticipate and charge the remainder of the liquid into the system but to make sure you are not overcharging. I would think that the hoses would have a 3 or 4 ounces maybe due to liquid in both the yellow and red hose. You could also work with 3' hoses instead of 5' hoses. The air makes one noise and is clear and the refrigerant makes a different noise and changes to vapor so you can tell. As soon as you see and hear the change you stop venting the air. Thanks for the questions!

We are going to charge a system at work that holds about 16 pounds of 410a tomorrow & I told my boss to get us a vaporizer for the gauges so we can charge the way we were taught.

They told him it’s ok to charge without it, is that correct or would we damage compressor charging liquid with no meter in line?

[@jamessalvia4839]

I always use a restrictor to flash the liquid to gas. Why risk hurting the compressor? You need to get a new supply house.

[@duanechildress1043]

you didnt show how and where to hook up the freon container?

[@acservicetechchannel]

Hey Duane, have you seen this one of adding refrigerant? Thanks- kzbin.info/www/bejne/hYTTl3WOndBjpLM&index=33&list=PLxnHR5_D2ojxTcAtR_53GoY8huBcSOt0a

[@sirvaant]

What is the reason for taking off the valve caps?

[@acservicetechchannel]

The valve caps for the ports or the valve caps for the stem? Ports allow pressure to the gauge set and the stem valves on three position valves allow front seat, mid seat and back seat. In the case of this system, it just has a two position valve with schrader valves in the ports, thanks

[@sirvaant]

Yeah not the caps for the Schrader valve but the the top caps that you took off for the service valves

[@acservicetechchannel]

We usually only take the caps on the top off for initial breaking the vacuum unless they are on a system that has 3 position stem valves. I may have just got done a pump down or breaking the vacuum and didn't put them back on yet, thanks

[@sirvaant]

Can you accidently break the vacuum by taking those top caps off the sevice valves?

[@David-pj2ro]

when using your gauges with different different refrigerants do you change your hoses?

[@acservicetechchannel]

I use different manifolds. I have quite a few. It really depends more on the oil than the refrigerant, thanks!

[@stevehayton746]

I noticed when you first connected your guages to the system, that you did not purge the air from the lines. Is this normal to do this? Also the connection where you connect the red hose, is this true head pressure or is this liquid line pressure?

[@acservicetechchannel]

That was just liquid pressure though some call it head pressure. Some purge the air before putting the liquid back into the vapor side and some purge the air right away. It won't mess up the readings either way, thanks

[@felipesolanet7469]

So you didn't actually add any refrigerant, did you?

[@kasanganelson7662]

pls help me with a link to the following , 3R's , how to read gauges and how to charge cos im interested in this trade.

[@tonyhamilton1503]

Is unit running at this point

[@acservicetechchannel]

Yes it was. My old mic canceled out the background noise, thanks!

[@rocker8692]

You don't like using an electronic leak detector?

[@acservicetechchannel]

I have two but there is no magic end all tool for leak detection. It always ends up being a mix of many, thanks Chad!

[@rocker8692]

Thank you

[@charlieb8417]

if suspected low refrigerant should you check with bubble Leak Detector even before removing caps? and then again after removing caps before attaching gauges? isn't the schrader valve the most prevalent cause of slow to very slow refrigerant leaking?? Should you replace your older valve caps with newer o-ring caps?

[@jacobkelley519]

allright!

[@kaosluv8676]

why cant air from the manifold gauge be let into the system? what effects does it have on the system?

[@acservicetechchannel]

It increases pressures and disrupts the saturated state of the refrigerant from transferring as much heat, thanks

[@redpost2380]

Somewhat disappointed that you forgot to purge the lines. It is a habit you must never overlook

[@rohailsiddiqui730]

Hi. I got HVAC certificat recently. I have to move an Air conditioner from one place to another. Please shoe video procedure from removal to reinstall AC by adding freon.. Thanks . R-Siddiqui

[@acservicetechchannel]

Thanks for letting me know what you would like to see Rohail!

[@rohailsiddiqui730]

Thanks for reply. I have difficulty only that how much pressure of R-22, R410A required to refill the unit for proper work.( how to calculate working pressure).

[@100dhanesh]

can i get job in hvac

[@acservicetechchannel]

Take some night time courses, keep showing up with your resume to different companies and don't give up- kzbin.info/www/bejne/iGi4kH6orpZ2eKM

[@DarreyonZone]

What is that cylinder on you blue hose?

[@acservicetechchannel]

That is an imperial quick charge cylinder for phase changing liquid into vapor before the compressor. I have used several types and this one really seems to work well imperial 535-c "kwik" charge cylinder

[@100dhanesh]

I want to work with you

[@acservicetechchannel]

I appreciate that but now I teach HVACR high school and adults at the local county technical high school and I run the business after school and build the online training. Good Luck in your Efforts!

[@thomast2256]

I love your video. I would like to ask you some questions. I think I miss some thing. In this video, you use 535-C KWIk charge and the air conditioner is OFF, in your next video. kzbin.info/www/bejne/hYTTl3WOndBjpLM I see the air conditioner is ON and you don't need 535-C KWIK to add refrigerant, can you please tell me what is difference between charging refrigerant and adding refrigerant. When we need 535-C KWIK or don't need IT. Thank you.

[@cavemanbgood]

Audio was bad. Hard to hear.

[@geoa9722]

So, you pretty much chwrged the system by trnasfering liquid from liquid line to the suction line as a vapor ?? So basically , we moved the refrigirent inside the pipes . Isn"t charging supposed to be ADDING refrigerant from refrigerant tanks ? Or from anothe cilynder ? Like recovery cilynder ? Where are the tanks ?

[@acservicetechchannel]

Hey George, this one was under the category of charging refrigerant but was just a video on checking the charge and doing the disconnect procedure so that you don't pull refrigerant out of the unit before disconnecting the hoses

[@geoa9722]

@@acservicetechchannelI see now... thank you, man.

[@mangalpadda8549]

You never showed your refrigerant can It is not that good To be a teacher you should show every little step

[@ttb6384]

I ll stick with words of advice this is confusing!!!

[@bjklawunder5610]

slow down man! you know your stuff.....we don't

Ok thanks for letting me know bj!
