How Professionals Recover & Recharge Your Vehicles A/C System 

Unlike some videos, your explanations are detailed which is what most people look for.

How did you know how much oil to put inside also should the high side be 200?

Great Video. I had a problem with wife's 2007 Camry. Thought it was a a possible blend door issue but turned out to be something different. Dealer wanted $2800 to fix the problem. $2500 for a new Control Panel and $300 for diagnostics. I said no thanks and drove home. Watched a few videos and talked to a few friends. Made a trip to the local auto store bought a can of A/C charge for about $50 and all is well in the land. No problems. It was just low on charge. We have no proof but suspect the local repair shop that we recently went to had let the charge out because I made them pay for a new radiator after breaking mine while replacing my alternator. They were also upset that I made them wipe off all the greasy hand / glove / paw prints off the hood and front of the car when they were done. Don't you love just love it when someone uses an oil filled rag to wipe up oil. I mean really, how much oil can a oil filled rag hold before it just smears it around? OK yer cars done!! That'll be $157.99 Please!! We even wiped'er down a bit!!

haven't watched your video but I know I'm always satisfied knowing a fellow technician is teaching future technicians __Eddy

Can it suck all the old PAG oil, even without the refrigerant in the system? (et's say lif you installed a new drier, compressor...ect. This way you can put in the correct amt of oil system requires, if you can remove all the oil from the system even from the new compressor which some comes with oil in it. That would be great if it can do that. )

Do you need to turn and run the engine when you doing this process?

Thank you for the great video, very informative. But I do have a question. When you charged the system with R134 you did not start your vehicle or turned your AC on. What"s recommended? Thank you in advance.

Frustrating I want to to know if all oil comes out At 5:44 i cant figure out what word is said referring to oil evacuated too. Can someone tell me what hw said?

So if you add oil to the compressor before vacuum, does that oil stay in the system during vacuum?

Great informational video. Can you or someone you know do a video on troubleshooting the LCD screen? Thanks for your time.

Hello!. I have a 2007 Eddie Bauer Explorer 4.6 V8. The AC never have been recharged and I realized that it is not cooling as several years ago. Can you help me to identify the Low and High ports used for recharge the air conditioning system with the appropriated gas and the maximum capacity of the Gas? Thanks a lot in advance!

If the system is empty because of an accident by a friend who accidentally hit one of the lines to the compressor and all refrigerant leaked out with psssschh it was a very warm/hot gas that was coming out. Ive replaced that small little line of like 30cm. What about oil then? How much to add? Did the oil escape out when the gas did? or can the ac machine still recover if any oil are still left in the system and then add the new correct amount? sorry for my english :)

big fan from Ireland I'm glad found someone as passionate about the job as me . one question did you always want to be a tech cus I definitely did keep wrenchin bud

I saw the option to recharge from both sides( Hight and Low) is that correct or something will be bad?

Thanks man. I'm in RU-vid heaven. I just watched a Schrodingers Box video, spotted yours on a good subject, and I'll be watching ETCG after this. :) HAHA. I wish this video came out a month and a half earlier. I would have looked smarter in front of the boss, but that's okay. Your thoroughness always teaches me something.

Great video. Have this same machine at work. It does a great job.

Hi, how and where did you inject the oil into the system? THANK YOU FRIEND

What a great tool! How far we've come from the days of slamming a can of R12 in to a system and hoping for the best.

Thanks for the video! I have a couple of questions. One is do you recharge with new refrigerant or do you use any of the refrigerant that was recovered? Also, I have a compressor whine only when accelerating. It doesn't do it at idle or If the compressor is off. If I have the system recharged if low, will that whine go away or could it be something else?

So when you drain the oil..does it take oil out from the compressor too ?

On a 1995 ford ranger 4.0 the a/c system calls for 1.9 LBS. What would cause a failure to compete the charge? We are using a KoolKare plus machine . This machine has the option to charge on the high or low side we have been trying to charge on the high side is this the proper method or should I charge though the low side. Thank,s for the vidos and keep them comming.

Thanks! Are you charging with the engine on or off? Also do you ever verify what pressures are in case you ever find yourself helping someone who only has gauges? I was surprized that you only put the amount of oil in that came out as opposed to putting closer to the system spec back in. Many times when a bad compressor is taken off it will be completely dry with zero oil in it. When it came new it had 4 oz's. I was wondering how the amount of freon is determined by the designer. Do the teach that info? Thanks! love the exciting music up front.

HELLO AMIGO EXCELENTE VIDEO SALUDOS DESDE COLOMBIA LLEVO BASTANTE TIEMPO VIENDO TUS VÍDEOS Y SUSCRITO A TU CANAL YO TRABAJO REPARANDO EL SISTEMA A/C HERMANO POR FAVOR HACELE TRADUCION A TUS VIDEOS SON DE GRAN IMPORTANCIA Y LA VERDAD NO LE COMPRENDO BIEN EL INGLES GRACIAS POR COMPARTIR TU CONOCIMIENTO

Had a question, I have an older robinair very similar to this, and it does not tell me to equalize hoses after charging. I end up with pressure still on the gauges after charging the system and disconnecting the hoses. I normally select recover after disconnecting hoses and get about .25lbs out of just the hoses. Is this .25 not making it into the vehicles system? My manual says nothing about equalizing like yours does.. thanks Dan

Ah so you had to inject the oil? I thought this thing did the oil too or maybe it just separates oil from freon?

recovery happens with the engine off? is there going to be any oil or dye trapped on any components that don't flow through with the system off?

Thanks for the great video. My mechanic says they will inject dye to make evident any leaks. Do you do that? Thanks.

Thank a lot for the class !!

What about the air that gets introduced when you pulled the low side hose off to inject the dye & oil? I know it's not much, but there has to be some in the hose if you break the connection.

I have a #SNAPON at work. I have never had to use it,I figured I would get ahead of the curve. Just in case I have to operate it..

After I went to Regas it failed and mechanic said I had a leak I took to a 2nd garage for 2nd opinion and that garage tried to regas said it hasn’t got a leak as there was gas in system but the compressor wasn’t kicking in which is why wouldn’t re gas 🤔

Very well explained. Thanks.

how much should you charge per vehicle when doing this service ?

If the compressor seized up and likely sent metal into the system, will that contaminate the ac recovery machine when recovering the refrigerant?

Hi When adding the Freon with the machine has to be with the vehicle turn off ?

Does the machine come with specs on refrigerant and oil capacities for different vehicles?

When you change a compressor do you drain the oil from the new compressor, measure it and put in the amount required in the system specifications?

One of the steps when replacing a compressor is to flush the system, but often people gloss over that step. I've seen some use compressed air, which seems like a strange thing to do since high pressure air will always include water that will condense everywhere. Is it common practice in the automotive industry to use compressed air, or do many shops use nitrogen? Is it common practice to use a volatile flush solvent?

Why no one of specialist youtuber talk clearly about Oil process ... The machine recover and drain the hole oil system including compressor oil...or just recover oil from condensor, evaporator, dryer and hoses only? How to know there is excess or missing oil? How to proceed with ideal oil charge with machine..or we should do it manually? I searched a lot on RU-vid, websites and forums..But i did not find anyone talking in a clear and practical way about this topic. For example: Oil chart :110 ml (hole system manufacturer's instructions)

thank you so much for the information been looking for this exact video for a while

I have a 2008 toyota corolla ce and a had leak on the low side port I change both valve low side port and high side port valve I did a vacuum for 20 minutes and I put a little oil in the system is don't know what I did wrong it's not cooling like before what the issue do the low side gauge reads 30

In your opinion, is it possible to damage the compressor by adding oil through the low side, since it will have to travel as a liquid through the compressor? Can the compressor get hydrostatically locked and damaged?

Wonder how you fix an a/c system that had been Open, then closed and charged with refrigerant and oil, and maybe too much of one or both?

Thanks for your time and effort to make these Vids !!! Cheers !!!!!

Hi. What’s your opinion and advice on mahle ac recovery machines. Why they come for hybrids and regular for separate. Does your robinair ac machine do the service for hybrids vehicles as well? Thank you boos.

I just bought the same machine. So far I like it but I am more familiar with an automatic machine. Can the Gauges be used on the machine after recharging as long as the panel valves are closed? I like to monitor the pressures to assure there are no potential blockages or other issues. Thanks ! I enjoy your videos!

How much does a Recover and Recharging A/C typically run to or at least ball park average figure? Thanks...

Question. If i take my car to a shop and asked them to recharge my system, do they add PAG oil back in??? I think i need PAG oil in my system as my low pressure line snapped, lost all refrigerant and i replaced it. I'm in NYC so i dont need AC right now, but just wondering if i have to put in PAG or will the shop put it in with the recharge?

thanks brian. best repair channel on youtube

How fill air for check leakage in ac lines

I’ve always seen these machines in the shops. Never got to use one.

Gr8888 Video and with clear details!!! I subscribed!!!

What should my pressures be on a 2011 F-250 high and low side?

Excellent video.

Do u always need a vaccum? What if u know theres enough in there for the compressor to turn on but not enough for it to be cold

I’ve got a question for you if I could. I just changed out a condenser in a 2010 Escape that had front end damage. While the garage was trying to refill the system it pulls a good vacuum but when it tries to fill it with the 1.56 lbs of Freon, it only gets to .6 lbs before it gives a failure code. Have you ever ran into this problem?

I have a 03 explorer limited when I have ac on the compressor turns on an off quickly an passenger side vent blows warm /cool air driver side blows hot an now lost my rear heat an ac any advice please

If my ford 99 f150 gets low on from I put a can or two in with gages and gets me thru fine. Must be a very small leak. Do you recommend from with the stop leak in it? Never tried that yet

,I have problem with my grand marquis 2005 ,the compressor going off to fast and run again when i start driving ,gas is OK compressor is new ??

Do I need to add oil when charging the system after pulling the vacuum?

Thank you for the video, Shouldn't you purge the air in the hoses first if you just want to check the pressure level otherwise air will get into the system? please clarify. Thanks

That Milwaukee toolbox is badass

Thanks again Mak! Wow that is some machine! Humans are amazing!

thanks for the videos I bought the same setup last year, I have the robin-air die injector gun and it is tiny. Where did you get yours sir?

how much does this machine or a similar one cost? and are they reliable or do they break down... also,If i wanted to open up an small ac repair shop in my area do i need a special license, I took an appliance repair coarse where if you work with refrigerant you need to take a special certification test ...i am located in sw florida... great video...thanks

my machine shows "oil drain error 2" when i recover or vacuum the system, what should i do?

Thanks for details will try to recover tomorrow refrigerant to take off ac off the car

And do you have to close the valves before you charge ?

Hi, I love your videos.. Great Work. I have a 2003 Tribute with 165k miles. I changed the compressor because of a bad pulley bearing. I used a re-man'd 4 Seasons compressor. It failed after about 8 months(leaked from the compressor). They replaced it, but the replacement had a bent pulley shaft which caused a leak. They again replaced it, but the third replacement was noisey from the beginning... Then it too leaked out the coolant. I gave up and went to a local repair shop. He used a NAPA compressor which lasted 3 weeks, and it too was leaking from compressor. The local shop re-charged the system about 3 weeks ago... So I'm waiting to see how this compressor works. Any ideas?? Each time the compressor was changed, I changed the receiver/dryer and orifice tube. The shop claimed to have flushed the system too. Thanks!!

Does it recover from high and low side simultaneously?

Where did you buy this machine?

Hallelujah!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How should I dispose of the a/c oil ? Same as regular oil

Can this machine use the old freon to recharge??

Does that machine flush the system also?

I over charged my 2016 Altima, sobI took it to a local ac person and they hooked it up to a machine like this and it’s still blowing hot

When did you add the refrigerant?

Why not charge on both high and low sides at same time?

How long does this process take

Great video as always, thanks for taking the time to teach us so much!

Does the vehicle need to run while you're doing all this?

Why the machine recover and drain 4 ounces of oil but you inject only 1 or 2 ounces..!? Any explanation.!

Does it suck most or all the oil out?

Thanks for the video

If you don't mind my asking, what does this machine cost? We need a new one, but I'm not sure what to get.

I heard that long term not using your A/C is bad for your A/C, is that true?

nice job

It keeps asking me for a serial number and I have no clue what to put

the system is recharged with the car off ?

Brian, You are a maniac! :) One question, where do you get large cans of refrigerant?

Great video and explaining. Are you knowledgeable with old Harrison A6 GM compressors.

Got my 609 cert. a few years ago - great investment come summer time... I searched your channel and I have a non-A/C question : On the Focus Mk1 (2004 SVT) is it possible to remove and replace the _front sway bar bushings_ without dropping the subframe? The end links are good but all the bushings are original double digit years old and it's time for a set of polyurethane bushings. I will also have the lower control arms off during the process but don't have a lift. ANY tips & tricks will be very appreciated.

2013 A/C question F150 ecoboost when not in recirculate mode using just vent I still get some heat into the cab,... so I have to use max A/C to get any decent cooling,... my question is can I pinch/clamp one of the heater hoses to get around this issue? which one? the dealer gives the typical everything is normal answer but there should not be heat coming in when I try to use the cool vent on a cool day,.... plus I dont get much a/c unless I am on max but i want fresh air a/c usually at night what do you think about that story? robert in niagara falls,.....dealers here are very bad!!

Hello,you did not show us how you injected the oil.

Thank you for this Great video .. but i have question ! most car dealer has common method to fill the AC when engine On and with pressure Gage , what is the difference between them . !?

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?

arent u suppose to turn ac on to max once you charge the ac system up?

Does a recovery unit like the Robinair RG3 have an oil recovery tank? I am thinking of getting one for personal use.

Can you explain the last step equalizing the system etc.... in more detail please.

Hello boss, I'm vacuuming 2011 but I can't reach -30 hg psi just -17 is that normal
