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
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
Thank you for explaining how to do a recovery in HAVC in different way
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!
Great informative videos for an entry level tech like myself, thanx!
Great to hear! Thanks!
just had a 5 year break and getting back into the trade starting Monday. this is a good refresher coarse.
Glad to help Colin!
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
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!
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?
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
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. ✨
Thanks for take time to show this i really appreciate that this my field it really help me
Glad to hear it!
I usually put that tank in some ice. Helps it recover faster.
Thank you for your videos, I have learned a lot. Very through and easy to understand.
Thanks Lester!
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 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!
Thank you for your videos.. I keep coming back to get a tip or two. You are very good.
You are so welcome
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.
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.
Awesome video! Thanks!
Thanks Adam!
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
Thank you so much this help me so much to do my job
Happy to help
You know this was six years ago…. It’s 10853673267855/lbs now 😂😂
😭😭💔
Right that’s what I was thinking
I don't always recover refrigerant but when i do its because the landlord is watching me 😁😁😁
2024 and this video help tons for my first recovery job
I have searched and searched. I can not find a video for recovery, from, not into, the outdoor unit of a mini split.
thank you very much for the explanation
Glad it was helpful!
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!
Good job on the video, thank you for posting.
Thanks for the video!
You're welcome!
great video!
Glad to help!
Thanks for a great video.
Glad you liked it!
Great video
Glad you enjoyed it
excellent explanation thank you for sharing!!!!!
Thank you very much!
Great explanation
Looking to try and recover r12 from old cars to have cleaned and processed for classic car restoration, thanks for the 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!
Ac service...big fan of youre video's...learned alot..allready got the e book......question:after recovery ,is the compressoroil still in the system?
If you use a recovery machine, probably about 95% of the oil will still be in the unit which is fine. If you try to do a partial recovery using the systems compressor, much more oil would be removed, thanks!!
@@acservicetechchannel thank you!
Great tutorial!
Thank you!
Exceptional tutorial. Thanks!!
Thanks Rx!
Thank for refreshing
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!
Thanks!
No problem!
Your videos are amazing, Thanks.
Thanks Daniyal!
Very informative.
Well done👍
Thanks Joshua!
Woooo!! Thank you for this!!
Thanks Richard! Look up "acservicetech full recovery procedure" thanks
If the condenser is working, can use the compressor to dump the refrigerant right into the bottle without a recovery machine
Yes you can, thanks
trukin forever what about on automotive?
AC Service Tech LLC Is there a vid on that?
P
K
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
Thanks man!!
How low do you pull down if you have a leak and dont want to pull non-condensables in your tank?
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.
And you're taking advice from Dupont. Yeah that's a great idea.
nice video
Thanks for the visit
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- th-cam.com/video/W1uhVvn57Nw/w-d-xo.html
wonderful
Many thanks
thanks for your efforts ...
Thanks Pei Broker!
All the videos be like:
1. Check yo equipment.
2. Evacuate.
While the first chapter takes about 98% of the video and the remaining 2% are the intro.
From what I am seeing most people are recovering in vapor, and here goes the golden question. Are todays recovery machines like Appion, ect able to handle liquid without the liquid damaging the machine prematurely.
Hey trukin forever, here are the manuals for both the Appion 1 www.appioninc.com/downloads/files/G1Single_Manual.pdf and Appion twin- www.appioninc.com/downloads/files/G5Twin_Manual.pdf -- I've been doing it that way for years, thanks.
Which way have you been doing it for years?
I was referring to our prior conversations when I was mentioning recovering in liquid and vapor all the way to the end or liquid and vapor and then at around 15 psi switching to vapor only. I sent you the product manuals so that you could see that they designed their units for liquid and or vapor. Thanks trukin forever
Thank you acservicetech and I will make sure to use your links to the product. Have a good day
Thank you very much!
Excellent video
Thanks Bart!
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
Thank you
great video, ty
Thanks Steven!
22 was 350 a pound lol times do change quick
You talked about purging air but I'm starting to believe air does not do much damage because there are videos where the TH-cam star neglects to purge yet claims success.
during a recovery, does it matter where your yellow hose is plugged in? (red or blue)?
is it good to use the recovered refrigerant to put in the system? assuming it is clean
Sir, you have a link for that filter drier? Inlet. Nice video.
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.
If your just starting out what is an affordable refrigerant recovery machine.
very nice thank you again!
I am glad to help!
Can you recover in liquid and vapor form at same time ?
Yes
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?
Max. 33 lbs. for R-404A
Yes each tank manufacturer and distributor will tell you what they are looking for in tank capacity, as well as tank purchase or rental, and price per pound of different refrigerants that they will purchase. EPA guidelines state 80 percent and we were going of of dupont's standards in the video. Thanks for your comment!
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?
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.
So you fill the recovery tank using the down stem line?
vapor should always be recovered before liquid?
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🙏
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
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!
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!
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
niyamai
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.
Can u pull both vapor & liquid at the same time?
good video is it possible to use the recovered r12 from a refrigerator to a older car that uses r12 (1992 etc) ?
iv'e recovered without filter dryer on pump is that bad fellas?
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
3:18
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"
Can you recharge the system with the recovery machine?
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 - th-cam.com/video/eKAGXek-KhM/w-d-xo.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?
5:41 - "All systems leak" so, what is an acceptable leak rate with regard to refrigerant recovery? Is 4oz per year OK?
No all symptoms don't leak. A properly installed system doesn't leak respectfully speaking ✨
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!
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.
does the reclaim process remove any of the oil?
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!
Wow LOL $3.50 a pound for r22. Here we are in 2022 and it's up to $1,400 a jug
