This is the best explanation I have come across on TH-cam on adding refrigerant to a central AC system. Thank you. I am a retired electrical engineer; I designed radio & TV stations, microwave links, and performed human exposure to radio frequency energy safety studies. As an engineer I like to understand other systems, so have been watching TH-cam HVAC videos. It's given me a better understanding of my home's HVAC system, and what the tech is doing during annual check up visits.
I looked around for someone that posted the "inner workings" of the AC gauges/manifold valve. This visualization is EXACTLY what I was looking-for. Pictures are truly worth a thousand words. The "logic" for proper usage is now thoroughly ingrained in my brain! A Big Thank You goes out to you!!
This is really great. I am EPA certified but it has been several years since I worked on HVAC so this has been a great refresher course for me. Thank you so very much!
Brother thank you so much!!! I haven't done this in a while and needed a simple, to the point refresher and that's what you did. Best thing since ice cream!!!
The BEST, there is no one of, just the BEST video about the gauge use in TH-cam!!! Thanks man! I thought the valve is for connecting to the gauge but actually it controls the connection between suction and charging! If I understand this then everything is understood! Other videos barely mentions this. You got to admit that very FEW people know how to teach!!!
Thank you, such clear & easy to understand teaching. I've been an electrical engineer for 30 years & am now going to train as a refrigeration engineer. I will check out if you have any other videos.
You have the best videos and do an excellent job explaining things! The graphics are very helpful. I appreciate you taking the time to share your knowledge!
You make things very clear to me. I am a special education teacher looking for a degree in HVAC. You are a genius in your presentation. Keep up the great work.
Purge air in the service line of the manifold at the refrigerant jug after purging at the manifold on the liquid and suction line. Make sure you have the red or liquid line CLOSED and suction line open at the manifold open prior to purging the service port or yellow line. Aside from the purging of the service line, this is an excellent instruction for charging.
nice video I was always doing install work and was never taught service in detail they always had a different guy come in that mainly did service but good to see videos break things down simply and help ppl start to understand the proper ways as I'm going into the direction to open my own business so I been attending youtube college lol but Na I had a great Co worker he us like a teacher to me taught me alot of stuff thankful for him for doing that
Great video, If I wanted to just check pressure without connecting the yellow hose and using a cap on the port, what is the best method to bleed the air out between the high/low ports before sweeping the gauge set back into the system?
With blended refrigerants, like R410a, you must charge upside down (with liquid). You should have a metering device inline with your charging hoses so you don't flood the compressor. With R22 you should charge right side up.
Refrigerant 410A is so close to being a true azeotrpe it's not necessary to charge it only like as a liquid. Most guys use it almost the same as R22. The refer just does not fractionate (fractionize) like other blends.
Hence the need for a metering device is not needed. I use it mostly in liquid and I have no problem meeting with my manifold gauge. I think that's the way it is with most guys. I taught for 15 years and I understand the dilemma of presenting curriculum material and balancing it out with practical application.
thank you for the nice explanation..and the regulation prohibit deliberate release of refrigerants to the atmosphere.. Should they be collected to a separate receiver when purging ?
I didn't see you purge the new refrigerant and what happens if there air in the hose when your adding refrigerant? And what are the other fittings on the manifold for they are no open are they?
Oh man the most Helpful video regarding the AC system of course for beginners I was searching online everywhere for this video I couldn’t find anybody else explained it Like that specially for people learning through vision so thank you very much very much for this This video for every person interesting Or home owners Please make more video in the future at the same simplistic way to understand Thank you so much
Thanks Ron have Great Knowledge & an are Great instructor .Indeed Thank you so very very much ..for i have learned so much from you already & I do study HVAC almost ever single day .on bleeding hoses iv been doing HVAC /R for 26 + years but when i hook up to an system I always Now bleed thu the charging hose by cracking then close the low side usually 1 st then then the hi side gauge handles & let the air & a small tad of gas or liquid escape thu the end on the center / yellow or charging hose that way iam sure the gauge body & the hoses or entire system & setup are all bled
This is a mandatory educational video for anyone working on any AC refrigeration work and especially Parker and Sons technicians, in Phoenix AZ who do not purge air and directly connect compound gauges and contaminate ac systems and sabotage the life expectancy of customers expensive AC systems
Hi! How do I recalculate/recompensate for the lost oil that goes with the refrigerant on recovery or loss? Is there any mathematical formula to determine how much oil is left on the system parts after the recovery?
Great job, of explaining how it should be done properly, I had a new set of gauges and didn’t have 100% clear explanation on which way my lines should be hooked up? my AC gauge lines has a 45° curve in the fitting and the other ends are straight, and on the yellow line on 1 end it does not have a valve in it, wasn’t sure if it should go towards the gauge or away from the gauge? Thanks
Very well explained, I only have one question though. Would you not turn your refrigerant drum upside down? or leave it valve side up? in other words valve side down or up? Only reason I ask is b/c I seen a service tech turning one upside down once and didn't really understand why he was doing that.
radcon821 Good question, you have to charge blended refrigerants in the liquid state (upside down drum). Shoot me an email at hvactrainingsolutions@gmail.com and I'll explain more. It is too long for a TH-cam reply.
When you purge the hoses at setup,do you loosen the connecting flared fitting AFTER you hook the hoses up or BEFORE and then tighten them after you get that second or two of purging gush? Thanks!
nice demonstration. if you are connecting a gauge set to a domestic refrigerator would you not end up with half the charge in your hoses ? how can you avoid this ?
if you will use an adapter between the vacuum pump and refrigerant tank or can, you can avoid purging the yellow hose during the charging process. doing so will insure 100% vacuum of the unit that is being charge with refrigerant. you can buy this adapter from amazon or make one. it is like a y or t setup where you can close the line to the vacuum pump after you reached the correct vacuum reading. also by doing so it avoid wasting refrigerant and releasing it to atmosphere. i suggest all hvac, refrigeration, and appliance repair technicians should use this type of adapter setup. i have read something that even r134a refrigernat is not safe to the ozone layer of the earth atmosphere.
Thank you for this video, I am new to this business and just want to recharge my AC. I just purchased the manifold gauge and noticed that it has two inputs to the flexible houses for each color, yellow, blue, and green. These extra inputs are located just behind the bottom inputs. Do you know the purpose of these? Also, there is some air left inside of the manifold gauge in case I use your purging technique, do you think it will be easier to purge the system from the red and blue housed into the yellow line before e it is connected to the refrigerant bottle? In this case, the valves need to be opened.
Yeah great video. Now, 5/2017, my ac guy is using 427a. Some quick fixers will put it on top of 22. I think it might be worth just doing a conversion replacing the 22. Have you the latest, simplest method for this? Your thoughts. Thanks, subscribing....

I'm a first year hvac student at a tech school and the see through image of the gauge really helped. Thanks.
Didn’t MySpace make you enough money. Lol
This is really great. I am EPA certified but it has been several years since I worked on HVAC so this has been a great refresher course for me. Thank you so very much!
Brother thank you so much!!! I haven't done this in a while and needed a simple, to the point refresher and that's what you did. Best thing since ice cream!!!
Mr. Ron, thank once again I'm gaining knowledge to your shared online training, wish you have more blessings and most of all good health...
I watched several vids on how to recharge the A/C (for my own house) But this one is the best and makes it perfectly clear. Thank you very much.
Thank you very much for your videos. I've gone thru a year of hvac course and still got one to go and your videos are helping me big time.
good video. this will help me out some. I am slowly moving over from install to service and start up
You are truthfully an Outstanding Instructor. Thank you so much for your devotion in teaching.
Gosh Ken thanks very much!

Great video, it was a please to watch and easy to follow along. Thank you for sharing the knowledge, and I wish you continue.
You can explain very well. You are like a professional. Thank you
Very nicely explained, particularly the functioning of the manifold.
Excellent job.... very nice explained. Very professional job.
Thanks a lot!
Thank You! Great video. You've have made us that much more aware!
Very professional explanation. Thank you !
this has been a great refresher course for me looking for curse that gives the exact reading thanks
Excellent, I HAVE NO WORDS NO QUESTION. THANK YOU.
Totally awesome explanation, really appreciate it

Wow! Awesome presentation! Thank you.
Great explanation true knowledge thanks so much
clear explanation thnx ! After this I finally understand how this all works and refilled my fridge at home !
nice video I was always doing install work and was never taught service in detail they always had a different guy come in that mainly did service but good to see videos break things down simply and help ppl start to understand the proper ways as I'm going into the direction to open my own business so I been attending youtube college lol but Na I had a great Co worker he us like a teacher to me taught me alot of stuff thankful for him for doing that

Most most beautiful that’s what I was looking for Sir appreciated you make my all points clear great sir and thank you very much
simple and amazing explanation thank you best regards
Great video, If I wanted to just check pressure without connecting the yellow hose and using a cap on the port, what is the best method to bleed the air out between the high/low ports before sweeping the gauge set back into the system?
I loved it so much. Being a handyman, this is very educative. Thanks
You can charge the high side with 410a liquid with a measured charge in an evacuated system and the compressor turned off.
Drawings ae always better than just explaing and showing actual valves illistration is perfect way thanks
great video you cleared up some of the issues I wasn't sure about
Rich O Thank you very much!
Ron Walker 不加评论
awesome video, just what we needed! thank you so much.
Crystal clear instruction!
Great video, better then what I have seen online, thank you!!
you explained it very well nice work.

it can be charged with comp running or no.
an experienced guy can do it either or.
thank you for the nice explanation..and the regulation prohibit deliberate release of refrigerants to the atmosphere.. Should they be collected to a separate receiver when purging ?
great video last i done it was in technical school this video is a refresher thank you sir
Great video. Clear explanation, and very detailed.
I didn't see you purge the new refrigerant and what happens if there air in the hose when your adding refrigerant? And what are the other fittings on the manifold for they are no open are they?
Good job sir. Thanks for the information!!!
Thanks for this vid I know I'm 6 years late but still very relevant and the best one I've seen!
You are awesome man! I am electrician and i understanding it imediatelly!
Great gauge information... Best I have seen so far. Ty
Very very helpful Thank you it really helped me..👍🏼
I love your channel dude, this is a very clear explanation. Thanks
thank you for that.... nicely explained

Excellent. Thankyou Ron.
Best explanation I have watched and I have watched many thanks.
Thanks Ron I'm in school currently Erwin technical institute your videos are a great help thanks once again!!
in tampa ? hows that going
+r4ym1n13 I finished school last month I'm working now to installs on new construction homes and trim work and installing condensers
thanks for the video. Question: Do you connect the gauges when the condenser is on or off?
Great instruction thanks for sharing the knowledge.
Great job Ron!
Excellent step by step video.
Thanks Ron have Great Knowledge & an are Great instructor .Indeed Thank you so very very much ..for i have learned so much from you already & I do study HVAC almost ever single day .on bleeding hoses iv been doing HVAC /R for 26 + years but when i hook up to an system I always Now bleed thu the charging hose by cracking then close the low side usually 1 st then then the hi side gauge handles & let the air & a small tad of gas or liquid escape thu the end on the center / yellow or charging hose that way iam sure the gauge body & the hoses or entire system & setup are all bled
thx for the video,if adding liquid to system with bottle r22 upside down can i do it through the low side?
Very helpful 👍i just have a doubt ,should we put up side down the refrigerant bottle when we are adding refrigerant to the unit?
Just the video I was looking for and more. What an awesome video, thank you sir.

Really great tutorial ... great tips. thanks
how do i detect if the manifold is stabilize
you do a very good job , god bless you
Thank you
EXcellent job and great training THANK YOU A++++++++++++++++++
Best explanation ever thank you
I feel like I finally understood how this shit works after countless videos I have watched in decades
Is it that this system can only be vapor charged?
nice demonstration. if you are connecting a gauge set to a domestic refrigerator would you not end up with half the charge in your hoses ? how can you avoid this ?
Ron...your right! It is Confusing! I just Bought a Set of Gauges and I did not know until your Video what was going on inside the Manifold!?
Where can I find the measurements for 3 ton r22 house unit York system ?
if you will use an adapter between the vacuum pump and refrigerant tank or can, you can avoid purging the yellow hose during the charging process. doing so will insure 100% vacuum of the unit that is being charge with refrigerant. you can buy this adapter from amazon or make one. it is like a y or t setup where you can close the line to the vacuum pump after you reached the correct vacuum reading. also by doing so it avoid wasting refrigerant and releasing it to atmosphere. i suggest all hvac, refrigeration, and appliance repair technicians should use this type of adapter setup. i have read something that even r134a refrigernat is not safe to the ozone layer of the earth atmosphere.
nice diagrams. really helps
Well explained..well done bro !
Great presentation, thanks.
Thank you for this video, I am new to this business and just want to recharge my AC. I just purchased the manifold gauge and noticed that it has two inputs to the flexible houses for each color, yellow, blue, and green. These extra inputs are located just behind the bottom inputs. Do you know the purpose of these? Also, there is some air left inside of the manifold gauge in case I use your purging technique, do you think it will be easier to purge the system from the red and blue housed into the yellow line before e it is connected to the refrigerant bottle? In this case, the valves need to be opened.
Great explanations!
Hi, do you add refrigerant while the ac is running? Or no. Thank you.
Is it necessary to have a kwik charge type of device while adding on the low side.
Great videos, keep it up... thanks!
You are welcome... more to come!
Yeah great video. Now, 5/2017, my ac guy is using 427a. Some quick fixers will put it on top of 22. I think it might be worth just doing a conversion replacing the 22. Have you the latest, simplest method for this? Your thoughts. Thanks, subscribing....
Dear sr.
I have scroll comp sometime it is got the suction pressor is so high like 95 psig.and the didcharge pressour is too los.
how its is come.
Does the system has to be running while is being charged?
