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
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.
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
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
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.
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!!!
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. ✨
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 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.
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!!
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!
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!
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?
When you have gauges on the psi should correlate to the temperature of the refrigerant. Look at a PT chart to check. When recovering you are just sucking out refrigerant. Shouldn't be anything other than that "bleeding"
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 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.
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
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.
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.
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
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!
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!
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?
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.
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 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?
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
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🙏
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.
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"
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
You talked about purging air but I'm starting to believe air does not do much damage because there are videos where the RUclips star neglects to purge yet claims success.
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
Usually we are recovering at that point anyway because that means that you lost at least 7/8 of the entire refrigerant charge and if refrigerant was added, it will leak out very very quickly. The pressure switch could be jumped temporarily but you would not want the system to run with a sat temp on the low side under 32 degrees or the evap will freeze and if the pressure gets low, it could damage the compressor, thanks!
TexByte2016. Charge firstly pure liquid on the liquid line. You can get almost a third the gas in with the machine off, then the LP will click on then add gas cautiously through the suction line
Yes, looks like neglected in the calculation is to multiply by specific gravity, ie WC weight (of R134A) x 1.2 . So an additional 20% can be added on top on shown in the video
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

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
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.
during a recovery, does it matter where your yellow hose is plugged in? (red or blue)?
Great tutorial!
Thank you!
vapor should always be recovered before liquid?
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?
Sir, you have a link for that filter drier? Inlet. Nice video.
If your just starting out what is an affordable refrigerant recovery machine.
I have searched and searched. I can not find a video for recovery, from, not into, the outdoor unit of a mini split.
Can u pull both vapor & liquid at the same time?
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.
iv'e recovered without filter dryer on pump is that bad fellas?
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.

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.
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 ✨
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"
great video, ty
Thanks Steven!
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.
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
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!
You talked about purging air but I'm starting to believe air does not do much damage because there are videos where the RUclips star neglects to purge yet claims success.
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
can i attach this tank to a diy ac iced box to get air conditioning ???
Very well explained! Much tanks!
Thanks Tomislav!
Question: My HVAC Unit has low pressure switches , how can I Recharge if Condenser won’t turn on?
Usually we are recovering at that point anyway because that means that you lost at least 7/8 of the entire refrigerant charge and if refrigerant was added, it will leak out very very quickly. The pressure switch could be jumped temporarily but you would not want the system to run with a sat temp on the low side under 32 degrees or the evap will freeze and if the pressure gets low, it could damage the compressor, thanks!
TexByte2016. Charge firstly pure liquid on the liquid line. You can get almost a third the gas in with the machine off, then the LP will click on then add gas cautiously through the suction line
What about the W.C. rating on the bottle? What does that mean?
Water Capacity. It refers to the amount of liquid refrigerant that can fit in the tank and we never fill it past 80% capacity, thanks!
Yes, looks like neglected in the calculation is to multiply by specific gravity, ie WC weight (of R134A) x 1.2 . So an additional 20% can be added on top on shown in the video
very nice thank you again!
I am glad to help!
Ty sir. Been a while.
Thanks Kason!
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
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
