what psi can one of theses tanks hold?
Please tell me what type of input filter drier shown here. Thank you. irascible51
There's no point in keeping the gas. Here just let it out. No worries.
What is EPA
I really like your educational video. It really made me feel confident again and I have not touch this trade in years. Thank you very much and please keep it coming.
Thank you Guardian Mn!
This is another excellent video on HOW TO. The amount of time taken to put this together along with supplying all the links to tools and equipment is fantastic. Thank you very much for the effort. I've got a project to do involving a vehicle overhaul project thus, this video is helping me to learn about the HVAC aspect. CM
just had a 5 year break and getting back into the trade starting Monday. this is a good refresher coarse.
Glad to help Colin!
Great informative videos for an entry level tech like myself, thanx!
Great to hear! Thanks!
Good job on the video, thank you for posting.
Thank you for your videos, I have learned a lot. Very through and easy to understand.
Thanks Lester!
Hello. Just wanted to thank you for putting up these very well explained videos. I'm starting on hvac and have found that your videos have been very practical in helping me perform a few repairs. Thanks!!! When possible would you please put up a video replacing a compressor? Thanks again!!!
Thanks Luis, I will keep that in mind!
It makes so much sense now I can see it being done before my eyes. The illustration they use in my class makes it harder to understand
Awesome tip about the liquid side, I knew not to pull Vapor from it but just was unsure why. Thanks man I’ve gained so much knowledge and love the vids
U are a godsend. I am a week from finishing school at TRI in manhattan and i find ur content super informative, detailed and e z to understand.
That's awesome, thanks adrnb237!
acservicetech do u have an instagram? Where do u currently work as in state and company?
I do not unfortunately. I teach high school students HVACR during the day and HVACR to adults at night at the local County Technical High School at the Southern tip of New Jersey in Cape May County. I also run my HVAC business but family first! As you can see, a lot of irons in the fire, thanks adrnb237
excellent explanation thank you for sharing!!!!!
Thank you very much!
Thank you for explaining how to do a recovery in HAVC in different way
great video once again Craig ... simple to understand. just purchased a g5 and megaflow hose and filter and filter hose and a 30lb recovery tank waiting on the g5 to come in a day or 2 from supplyhouse. I do have a navac vacuum pump that I love. but I went w the the Avion g5 recovery machine .. g5's size is so much more space saving. I like that navac is digital but it maybe one part that can break then be a big issue. think I made a good choice choosing the g5. even tho hvac school ran a test w navac vs thr g5 and it's only minutes in difference which isn't that big a deal to spend more money on a navac.
Looking to try and recover r12 from old cars to have cleaned and processed for classic car restoration, thanks for the help
Great tutorial!
Thank you!
Exceptional tutorial. Thanks!!
Thanks Rx!
Thanks acservicetech! nice video. Very easy to understand, I like how you use the actual tools to show how it works.
Thanks, glad you enjoyed it.
Thank you for your videos.. I keep coming back to get a tip or two. You are very good.
You are so welcome
Very informative.
Well done👍
Thanks Joshua!

Thanks for take time to show this i really appreciate that this my field it really help me
Glad to hear it!
Awesome video! Thanks!
Thanks Adam!
Woooo!! Thank you for this!!
Thanks Richard! Look up "acservicetech full recovery procedure" thanks
Thank you so much this help me so much to do my job
Happy to help
What type of filter drier you use for the recovery machine? Is it the same type you use for residential systems? Could you please add it to the tools list? Thank you!
thanks for your efforts ...
Thanks Pei Broker!
Great explanation
thank you very much for the explanation
Glad it was helpful!
Thanks for a great video.
Glad you liked it!
Thanks for the video!
You're welcome!
great video!
Glad to help!
Sir, you have a link for that filter drier? Inlet. Nice video.
Hello. Would you do a video on how to use a one time recovery cylinder? Thanks!
Hey Mr. Tinieblas, I only use reusable cylinders. I will be putting more recovery videso out soon but here is one for you for now, thanks- ruclips.net/video/W1uhVvn57Nw/видео.html
great video, ty
Thanks Steven!
Thanks man!!
Thank for refreshing
Great video
Glad you enjoyed it
Reclaimed R22 can be reused...especially after Jan 2020. Keep for old AC service calls!
Youra Ninee can only be re used for the same unit or the same household
Current EPA 608 guidelines only stipulate use in the same owner's units to avoid cross contamination, thanks!
very nice thank you again!
I am glad to help!
good video is it possible to use the recovered r12 from a refrigerator to a older car that uses r12 (1992 etc) ?
I'm 16 and I'm going to votech to do hvac and I love it
Awesome, stay hungry and learn as much as you can!
Thank you
How low do you pull down if you have a leak and dont want to pull non-condensables in your tank?
great video! would it work without the recovery unit. say i hooked the yellow line directly to the tank, would the compressor be able to get all the refrigerant out of the system that way? similar to a pump down.
Yes it would. That is called system dependant recovery, granted the compressor may have a hard time doing it do to age and you may need the self contained for the last part since the compressor uses the refrigerant to lubricate and cool, thanks
ty good vid. Where do i sell refridgerant ? i have a 4ok. btu unit , damaged but still blows cold. i don't want to pollute and need some loot ($ ) ty.
Can. You put the recovery cylinder in ice if you cant get the full charge in the cylinder?thanks
Do you revover r410 the same way as you do r22?the reason im askink cause r410 is only charged as liquid....because its a mixture of refrigerants!!!thank you ur one of the best in youtube!!
Hey Victor, yes you do and you will be taking all of the refrigerant out of the system anyway so you will maintain your mix. If you suspect a leak then stop at 0psig so you don't pull air into the tank. If you only need to pull a little r410a out of the system then while it is running, dump the liquid into the recovery bottle on the red side then. Thanks!
You're always weighing part of the hose, right? Should the initial weight be taken with the hose removed? Also, you didn't mention purging the recovery unit after the initial recovery -- is that required on that recovery unit?
Great informative video! One question though, if you have recovered what is suspected to be R134a and a mixture of air and moisture from vacuuming a system with a leak, into a recovery tank, is there any quick known ways of being able to seperate out if you decided you wanted to re-use the refrigerant gas? I know the boiling point of 134 is about -30 celcius so in theory if you froze your recovery bottle and drew out of it in such a way that only liquid was taken, you could say chances are your gas is pretty pure, any moisture will have frozen and could be filtered out etc. Cheers
vanepico. with that slight amount, might get away with purging the bottle (air rises) vent off the vapor outlet, then install filter/drier. If things are more dubious, replace with new gas.
It's important to stop a recovery above zero psi
I usually put that tank in some ice. Helps it recover faster.
Do you need an extra hose or can I use the high side hose to recover? because all I have is the gauges and the hoses on it.
Thanks!
No problem!
does it work on vaccum or what pulls the refridge out from the system?
and nothing is actually pulling any moisture out from the yellow hoeses?
So you fill the recovery tank using the down stem line?
Why did my Appion struggle as if there was a a slug of refrigerant having difficulty passing through it also had to be shut off and the restarted a few times after I throttled down the inlet on the recovery . at one point the recovery machine was really shaking machine. Any thoughts on what I am doing wrong,? I also had a filter being used along with recovery hoses.
wonderful
Many thanks
Can u pull both vapor & liquid at the same time?
nice video
Thanks for the visit
Do you have a link for the filter you used between manifold gauges and the recovery unit?
These are currently unavailable but fpor your research here is a link- amzn.to/2nFcU9z - You would only use something like this if you were reusing the refrigerant.
does the reclaim process remove any of the oil?
Hi bro if the compressor oil is mixed with gas R 22 or any Hvac refrigerant..
We can separate gas from oil...??
We can Store the gas on reuse cylinder. With recovery meachine..??
we can reuse the gas is possible....??
Please advise me pro🙏
during a recovery, does it matter where your yellow hose is plugged in? (red or blue)?
Great video and I liked that you mentioned how to bleeed the line first. Very important if you plan on recycling the refrigerant, along with the filter/dryer of course.
Absolutely, thanks!
You know this was six years ago…. It’s 10853673267855/lbs now 😂😂
😭😭💔
Right that’s what I was thinking
It doesn't look like I can rent a recovery machine- I have the tank and lines, but the only pumps I could rent locally are for recharging and don't have an outlet for the tank. The vehicle I am working on is my track car that I am removing AC from and isn't street legal to bring it anywhere. Is there anything I can do to remove the refrigerant properly?
When you use that filter dryer that you put on the machine, can you clean and reuse the filter again?
We typically just build it into our price and keep a 1/2 dozen in the truck with us, thanks Noah!
question, can you use a standard HVAC/A/C vacuum pump (the same pump you would use to run a vacuum through your A/C lines with) with just the tank and gauges to recover refrigerant?
Justin LaFleur. No they are different machines altogether. Unfortunately. The vac pump doesn't have a usable outlet port, and operates at quite different "pressures"
nice video! how about the recovery machines that say purge! how do you purge the recovery unit?
Great Question! So the purge feature is for recovery machines that bring refrigerant into the crank case. After you are done recovering you switch the tubes with the purge lever and the unit pumps the refrigerant left in the recovery unit into the cylinder. The style used in this video does not have a condenser or lots of tubing that would have as much trapped refrigerant to purge.
I have a bacharach stinger and been trying to figure out how to do that. I don't want to release what's still in there into the open. instructions aren't to clear.
Can you recharge the system with the recovery machine?
I don't always recover refrigerant but when i do its because the landlord is watching me 😁😁😁
Sir i have a question can i do a vacuum all together like recovery cylinder ,recovery machine,and hoses?
You would need a vacuum pump and valve core removal tools such as the appion version. Have you checked these videos out yet?- ruclips.net/video/jlzecsOImqs/видео.html
I noticed you're using an Appion. How exactly do you purge this recovery machine when switching between different refrigerants (for my work I generally work with R22, R410A, and R134A)? Was thinking of buying a G5 Twin but I want to make sure I can use it on multiple refrigerants.
Hey Sandro, Here is a link to the Appion G5 Twin Recovery Pump amzn.to/2dGSEyr -- My appion recovery machine just has a type of impeller inside. These types don't need a certain amount of refrigerant going through to lubricate or cool the motor or compressor. I would mainly be concerned with reusing the refrigerant out of what was an empty recovery bottle. Otherwise at the supply house for exchanges, they just hook the pressure gauge up and they check the sat temp to make sure there are no noncondensables or other refrigerants inside and for that I would not really be concerned with unless they were. My supply houses are not concerned. Here is a link for a refrigerant exchanging process - ruclips.net/video/eKAGXek-KhM/видео.html
Ah ok, thanks. I've heard some people complain about the tank pressure skyrocketing on hot days, and the Appion manual recommends recovering with 3/8 hoses instead of the standard 1/4 (which is all I have) to avoid restricting flow. Is this absolutely necessary or can I get by with my 1/4 hoses?
niyamai
Question...can you recover in liquid into the vapor(blue port)and just flip the tank upside down?
Most of our small recovery machines do not handle liquid but just either saturated refrigerant or vapor refrigerant, thanks!
AC Service Tech LLC up
Hi, really like your videos! Can you use the same refrigerant recovery machine for different refrigerants?
I do car A/C , and will soon be setting up with HFO123yf, want to avoid buying a new recovery machine if possible. ( all of my equipment is separate like yours ) .
Thanks
It is best to avoid refrigerant oil contamination or mixing what was in the hoses whenever possible. If it is not possible, then they should be blown out with nitrogen and drained as best as possible. Thanks
Cool, so as long as i clean the hoses out ( or probably just keep my hoses separate ) then I will be ok to use the same recovery machine but with a different filter?
I believe so but just check with your distributor who will buy or exchange your bottles. As long as they see the correct pressure and sat temp on the bottle when exchanging and you are not reusing the refrigerant from an empty recovery bottle, you may be ok. You should check with whoever is exchanging your bottles first, thanks. here is a link on this - ruclips.net/video/eKAGXek-KhM/видео.html -- Here is a link to the Appion G5 Twin Recovery Pump amzn.to/2dGSEyr
I’m sure it’s obvious but I’d rather know before finding out through experience. When bleeding the air how do you tell it’s refrigerant when completing the bleeding?
Hi! How do I recalculate/recompensate for the lost oil xoes goes with the refrigerant on recovery? Is there any mathematical formula to determine how much oil is left on the system parts after the recovery?
piston ring. Very rare to consider the oil lost. UNLESS the leak is on the base of the compressor and lost oil is obvious pooling in the unit. Some larger units have an oil sight-glass that helps.
But 99% of time don't worry about a fraction of lost oil
Thanks
where should I look to buy a used recovery tank that I can recover with? also if my system has a leak and I recover the refrigerant will oxygen get sucked in from the system into the tank?
I would not know where to get a used one from and you would really want to know the person you get it from. For instance, you would never buy a used vacuum pump do to how low of a vacuum it can pull do to lack of oil changes. You would still use the same setup but just recover down to 0psig. When you have air in tank, you just will not get paid for the refrigerant since it will not correctly measure out with the p/t chart when exchanging at the supply house, thanks
Do you pull a vacuum on the recovery tank first, and can you start with the tank in a vacuum?
I usually pull the vacuum on a new recovery tank right before using it to make sure that the vacuum is still present before breaking the vacuum with refrigerant, thanks!
I just bought that appion g1 single recovery machine at a pawn shop for 138. I was looking for a g5 twin but the cost is triple. I got a good deal. I hope it works well. Looks good on the outside atleast.
You could run a test with two partially filled recovery cylinders to see how well it works, thanks
anyone can help please do
I am apprentice My problem I just recovered R22 from a old Russell unit cold box the reason I had to is because the customer wants the unit move a few feet back so I cut the pipe already capped the ends off and will be reinstalling pipe Monday. My question is after I install pipe purge, braze, will it be ok for me to put a vaccum pump on it? I was concerned about the refrigerant oil in the system will that damage the pump? Or will there be any oil in there after my nitrogen test? If anyone can help me I greatly appreciate it
2024 and this video help tons for my first recovery job
If your just starting out what is an affordable refrigerant recovery machine.
this isn't on the subject but can you do a video on heat pump heat mode true suction i got but what pipe the discharge is flowing through now? and why do some heat pumps have no ambient and coil sensor, it funny I'm recovering right now lol
Nice! When hooking up to a heat pump in heat mode, suction would be the middle port and the discharge is the large line. The liquid line is still liquid but now headed toward the heat pump metering device. Some defrost are timers are just not equiped with a temp sensor which is not a very good design. They use time to shut off instead of the dft sensor.
Nice video. Keep in mind viewers - It doesn't matter what color knob is on the port Red or Blue either one can be a Liquid Or Vapor (gas) depending on the can that you've purchased so read your valve labels whether it is liquid or vapor to know which is the proper connection, Respectfully Speaking. ✨
so what you're saying is that, it is always safer to plug the hose into the vapor port of the tank right?
That has been my experience but more importantly just don't put vapor into the liquid port. Yes you could put liquid or vapor into the vapor port of a 50lb tank. Thank you for your question!
can i attach this tank to a diy ac iced box to get air conditioning ???
vapor should always be recovered before liquid?
Hello ac service tech! I'm trying to solder a copper pipe to the accumulator on compressor of a window unit. Any ideas what to use? I've used 15% Silfoss but still leaking on me. The accumulator I believe is steel and won't catch to well.
You can use Lucas Milhaupt 380, 560, or 505. 560 would likely be the best bet but any of those should work. Make sure to use a liquid rubber product or wheel well paint when you are done. Thanks!
acservicetech great! just watched a video on lucas milhaupt copper to steel solder and they use the 560. Thanks! This liquid rubber or wheel well what is that if I may ask?
plasti-dip amzn.to/2emwtkX
--------amzn.to/2e98Ji0----------or wheel well paint, it doesn't have to be this brand because you can get it at any auto zone or advanced auto parts, napa if needed----amzn.to/2eJIKzJ
First of all great video thanks for uploading.
Question: Near the end step, when we open the vapor valve from the gauge it flows through the center of gauge, into the recovery machine, then OUT the recovery machine to the entry point of the recovery tank right. I'm wondering what's going on inside the recovery machine. Without the machine turning on, the vapor will still travel through the inlet and outlet of the recovery machine?
If you have a leak in the system how do you keep from recovering air when it's starting to pull a vacuum at the end of recovery?
You just don’t pull it into a vacuum. You’ll just have to lose a little refrigerant
Everyone in this conversation is retarded!
@@dakay94 doesn't understand a simple conversation and calls everyone else retarded.
@@Slammo2001 explain what we're talking about and why we're retarded.
Awesome video as always acservicetech!
Do you know how one would add an oil separator in line so that the Appion G5 could be used for Automotive use also?
Sure it would pull 3.5 lbs of freon out in a flash but the oil has to separated out and usually discarded. That way following AC systems don't get over oiled.
All of the very expensive programmable automotive recovery machines have oil separators.
I know that oil separators are installed in between the compressor and the condensor because the freon has to be in a gas state to separate the oil out. Any ideas?
Possibly the "yellow jacket 38087" but that may be a little more than what you are looking for but I think that would work depending on the amount of oil we are taking about. Any small amount of refrigerant oil that ends up in an HVACR recovery tank is taken with the refrigerant in the tank and exchanged for a new recovery tank at the distributor. Thanks Blade!
That 38087 is a bit expensive! I have the Appion G5 ordered now so that'll be one more major tool to fasten to my belt. It might be a bit heavy though. LOL!
I've hit auto AC hard for 2 years now not just studying but finding and fixing problems as well as electrical issues. I'm also very interested in HVAC as well so I watch plenty of HVAC stuff and have enjoyed your channel immensely. Thanks!
Yeah, honestly you may not need it unless you need to weigh how much oil you are taking out to know how much you need to weigh back in. Just so you know, I don't use the 38087, I just looked it up for you, thanks!
acservicetech Well they typically pull out 1 oz or 2 of pag oil, discard it and put that much back in new.
Ok, yeah then maybe you want to get an oil separator to verify how much, ok, thanks
ac service how long would an inline dryer last on a recovery unit? thanks...jamie
You would change that each time if you were concerned about the refrigerant in the tank or the recovery unit. We build this in the price of the job. A burnout would certainly only be used one time and is needed to guard the recovery unit.
acservicetech thanks man.
Thanks for your video! Very on point and informative. Question - when recovering R134a from the car - do I do it from the high (liquid) side or low (vapor) side or both together? I assume the car (including AC compressor) should not be running during this procedure, correct?
I had the same question.. did you find the answer? I would think that you would not be running the engine at this point, only during recharge.
@@whereisthehook , correct. Running the engine during the recharge only.
What about the 300+ psi on pumps high side line? Just purge it? there is no way to recover that line.
Optimally I would say.. dedicated hose with valves or shraders.
On a recovery machine without a purge function yes it would have to be purged but a recovery machine with a purge would pump this into the recovery tank, thanks!
Excellent video
Thanks Bart!
hoda video ekak
Hi you’re so good ~~
But how to put it recovery to compressor
Thank you 🙏
I have a video on adjusting the charge using the running compressor but you don't want to recover a lot using that method due to the oil being removed from the system, thanks look up acservicetech recovery using the compressor
AC Service Tech LLC
Thank you ~~~~~
If i want to recover all the refrigerant only in vapor form, can i just open the low side only . Im a student of Auto hvac system
Yes that is correct, thanks
Do you primarily recover in vapor because it is safer for the machine, and if you did recover in liquid how do you know when to open your vapor side of the gauge.
If you recovered in liquid or in both liquid and vapor just wait until you are at 15 psi or so and then just start recovering vapor only. It is not less safe to recover in one or the other for these types of self contained recovery devices just the older style ones which wanted vapor only. Thanks!
acservicetech wait until you get to 15 psi on high side or low side
High side
