By the time you finished that extravagant setup and explanation, I'm done. Never removed cores and it's plenty fast for 5T and under or 15 lbs of refrigerant. If you are changing out a system, lay a wet towel on top of the recovery tank, put a fan on it to keep it cool and start disconnecting electrical, pulling blowers/heats out of air handler, unhook duct work.
I find a huge problem with the many of these type videos, especially on the recovery, vacuum and charge of refrigerant, that many of them have enough differences on detailed procedures, and that anyone trying to learn the absolute correct procedures to prevent future premature failures would not have any guarantees from any that these videos will give them the best possible results. I've seen this in all the trades, but this is one of those procedures that seems to be much more critical than other trades have to deal with if things are NOT done properly.
I wish you be my teacher ..I love the way you teach .. Thank you for all your videos .all I know about AC I learned with you and not with my teacher at school.. Thank you so much.. GOD BLESS YOU ..
That’s not always true as it is not easy recovering a unit down to its motor oil (compressor oil) .. The majority of time its simply Air .. and if any oil was to leave the unit and enter any recovery unit you will hear its compressor “screeching” from time to time during the recovery ..
At 5:45 you mention regarding the refrigerant transfer you mention "unless it's from the same owner". You mean vendor in regards to refrigerant/oil content or system owner in regards to legislation or rules prohibiting refrigerant (freon maybe) transfers. Great content!
For vacuuming a system down it can make a difference with a large can vacuum pump. With some Appion vacuum hoses, and accutools core removal tools, and a 10off pump….I can have a micron reading so low in minutes. It Would blow your mind how fast it is truly. Now for recovery I don’t see this set up being any faster. I’ve seen guys put the recovery tank in a 5 gallon bucket with ice, and recover it faster through a manifold.
This video was not all that excellent and actually it could be a little confusing for the novice or someone such as yourself (no disrespect) .. the hose set up was over kill, he did not use a manifold, and the procedure was done kind of out of order ..
Believe me I do understand the larger hose thing but it's still pulling through 1/4 inch ports. I worked at a public utility so there was never a need for rushing , as soon a we hooked all that up it would be BREAK TIME!!!🤣😂🤣😂 Always looking for new and useful information which this channel Always provides, and for that I do thank you!

Out here in California, San Francisco , minisplits, Mitsubishi in particular. I would love to see you do a full Mitsubishi, Samsung, or Fujitsu install.
Excellent video, very well explained, I have a cuestión: I missing the part that you said that the hose have to be connected to the tank liquid valve port, I think there’s not color codes for the liquid side valves or knobs. Thank again for this great Video
This is amazing. I did have a question as, I was taught something slightly different. When you are purging the air in the service lines, before allowing refrigerant to enter, why did you not lossen the hose to the taken to allow air to escape as you open the megaflow valves. I was taught that air can mix with the refrigerant if you do it that way, thus essentially making your uncontaminated bottle now contaminated. Am I inaccurate?
Thank you for the videos. It helping me a lot as a new technician. I have this nasco split AC that sends power to the outdoor after after 10 minutes of putting it on. The outdoor unit works for 5 seconds and goes off for another 10 minutes. When the out door unit is on , the indoor fan goes off till the outdoor goes of again. Please what may be the problem?
Thankful for you craig .Perfect explanation . Just I have a question when said 2 or 4 at that prrussre you stop recovery machine it was 2 , 4 psig over or below the 0 psiag . Thankful for you dude
Hi Greg, can you give me the link to the 1/4" x 3/8" x 3/8" tee, the plug pieces for the hoses and the pressure gauge, that would be great, love your videos, thanks
Fantastic video Craig! Love your book and workbook. Need to get myself that wye and the 3/8 recovery hoses. Thanks again for all of your excellent work!
Yesterday, two "experts" did some maintenance on our AC at our house in Indonesia. They probably just vented the refrigerant in the air. That's how they do it here and in many other countries too, I guess. What are your thoughts on this? IQ is about 78 in Indonesia. Motivation for improvement is very low too, I guess. Having a normal conversation with these guys is probably very complicated besides not knowing their language.
Watching this trying to learn something. my scenario is for Car AC, slightly different than this scenario. My question is can I hook a black hose from red port of recovery machine to the tank in my scenario or it needs to be a specific color?
I have a question. If after a while of sitting the refrigerant gets saturated, which if I'm understanding correctly means there's gas and liquid mixed everywhere inside. If it's on the evaporator side how does it not damage the compressor on startup? Wouldn't liquid enter the compressor?
After you completed the second recovery, where the unit stayed in a low vacuum, why didn't you start shutting off the valves like you di at the condenser, and work your way back to the recovery cylinder through the recovery machine shutting valves as you go. Wouldn't this prevent diminimus release and capture most all of the refrigerant in the cylinder? Thanks.
So what's the need for the filter drier if recovered refrigerant is supposedily bad and not good to reuse? Are you just trying to protect the recovery unit itself?
The red outlet from the recovery machine causes technicians to connect the red outlet of the recovery machine to the red liquid port of the recovery tank instead of the vapor. AC service tech, Can you explain what happens when they do that?
and should I have left it to keep trying to suck down to hg? like 2 or 4 ? because once I got to 0 it seemed to take alot longer to try to get any lower
Beautiful tutorial! Clear and concise as always. Kind of a random questions: Why is there a minimum and maximum line set length for systems? (traditional and mini-splits) I would think that making the line set as short as possible would be ideal for similar reasons to why you would want to minimize your vacuum hose length. Do systems not function properly if the line sets are too long or short?
This was NOT a good tutorial .. over kill and not properly explaining the procedure correctly .. as far as the procedure he would have not been successful actually recovering that unit and you ALWAYS recover the unit to a slight vacuum (pass zero psig into the mercury inches)
The MR45 is great I use it everyday for changouts and it’s easy enough for even new helpers to get the hang of it especially with auto shut off and a digital screen to show pressures.
I use a refrigerant analyzer on all my R 22 systems. Here in San Francisco we have a lot of people who come from countries who do not care about EPA and cross contaminating refrigerant and just dropping one refrigerant on top of another refrigerant especially those so-called blend drop in refrigerant. And the drop in refrigerant when you try to use the PT chart will show up as R22 Because the inside coil and all the refrigerant lines are at one temperature and your outdoor condenser is at a different temperature so there’s absolutely no way to get an accurate pressure reading. It’s just speculation and guessing that it is R22 or a blend or a contaminated mixture of the both I have always owned refrigerant analyzers since 1993 and they were very expensive at the time back then but I still felt it was more than worth it. Because while everybody else was doing misdiagnosis when systems had air contamination (noncondensibles) I would diagnose it correctly 100% of the time whether the refrigerant was clean and pure or not because I had a refrigerant analyzer. Do it once do do it right. And a lot of reuse refrigerant tanks and sometimes brand new refrigerant thanks leak at the valve packing at the stems of the knobs when you try to pull deep vacuum the technician can pull air in. But NYLOG fixes this problem
Stick your analyzers and that nylog crap where the sun don’t shine, and the freon will always travel to the coolest place and that will determine the system pressure !
@@nunyabusiness6746 analyze is always 100% right when it comes to analyzing pure R 22. And when you’re dealing with large systems with several hundred or several thousand feet of pipe you don’t know what the coldest places is it a pipe that’s buried in the wall the pipe underground is it the pipe above the ceiling in the hallway in the offices but we won’t think about the pipe that’s traveling under the roof at 130°. If I wanted to transfer refrigerant from one container to another container yes the refrigerant will travel to the coldest place I’ll stick one tank in the freezer and leave one tank outside in the sun and it all go mostly not all to the cold tank. . But unless you’re going to go travel throughout an apartment building or a 2000 room hotel in sick temperature clamps on all the pipes in walls floors and ceilings to find the coldest one so you have an accurate temperature yeah right when pigs fly.
If he was using a manifold he could have shown you, check your PT chart for the refrigerant inside the unit, if it doesn’t match the temp/press on the PT chart for that refrigerant then you would know if its air or refrigerant .. Air is lighter than refrigerant so it will come out of an enclosed pressurized container first (according to our Dalton’s Law theory)
If you pump enough refrigerant into the tank so the pressure reaches equilibrium between gas and liquid then adding more vapor will immediately turn some vapor into liquid.....no?
craig quick question... so after getting it down to 0 on the single gauge then shutting off the crt valves, will the pressure rise a few psi back up or it has to literally stay at 0 ?? used this procedure for the first time w pretty much everything you have I didn't flip the tank over I put the r22 back in through the vapor side. ....
Just bought your book on Amazon. Looking forward to getting it tomorrow. Question: Why were there 10 pounds in the system? 4 pounds (right?) over the manufacturer's plate.
Buy a variety of hand & some power tools first. Your company may or may not provide you with essential HVAC related equipment (Recovery machine, Vacuum pump, Torch kit, etc), Some stuff you'll likely need: Sets of pliers, needle nose pliers, adjustable wrenches, 11-1 Screwdriver, 6" Precision screwdriver to adjust control board and thermostat terminals, Cordless impact driver, multi-meter with an amp clamp. Companies will likely have a tool list. If not, your co-workers will let you know.
Every time you open the system up to the outside environment, you are technically required by all the manufacturers I know to replace the filter dryer.
hey Craig so this 15$ filter dryer I just ordered from supplyhouse ... it can only be used for one recovery ?? thought these were re usable til they pretty much started to show signs of constriction

The rise of pressure is usually caused by refrigerant trapped in the oil.
I’m a 40+ year HVAC&R service technician
Cool story bro
Really true ,I saw a video about PAG oil , the refrigerant kept evaporating from oil for minutes after recovery.
That’s not always true as it is not easy recovering a unit down to its motor oil (compressor oil) .. The majority of time its simply Air .. and if any oil was to leave the unit and enter any recovery unit you will hear its compressor “screeching” from time to time during the recovery ..

@@acservicetechchannel thank you for you fast reply! 👍
Just purchased 3 of the Appion valve core removal tools. Great quality compared to the Robinair ones I purchased a couple years ago.
They are not necessary and really doesn’t make any difference from using a manifold like the traditional HVAC technicians do

Are you sure the small amount of added weight over the tare weight wasn’t the weight of the attached hose?
I find that pulling through my manifold with no shraders works well enough for me. (As long as all gaskets are good)
Gaskets!
By the time you get done screwing around with the shrader valves you could be done with the job!

How do account for the weight of the hose, you initially weighed with hose connected
Thankful for you craig .Perfect explanation .
Just I have a question when said 2 or 4 at that prrussre you stop recovery machine it was 2 , 4 psig over or below the 0 psiag .
Thankful for you dude
How often do you need to change out the dryer filter on recovery machine
Thanks 👍
Should make a list of the items used in this video.
After recovering All refrigerant from (mini split),do we need to vacuum it down the outdoor unit or just the line set? Please help me I’m a rookie
yes i do vacuum it to check for any leakage and make sure its clean and total empty
Can you show us how your service car is organized?
Where do you find those black 1/4" hose plugs with the finger hole? I like the idea of using those to keep the hoses closed off when not in use.
The brand is APPION they come with hoses when you purchase. They are metal now but were plastic on older ones
Can use this procedure to remove refrigerant from Freeze Dryer before taking to Brazil. Taking notes of qty and psi so can recharge in Brazil
Hi Craig! Do you use a new filter every time for the recovery?
Can you do a pump down and the n close the valve and recover the rest of the refrigerant
How about the weight of the yellow hose to the tare weight? Is this a significant factor or is this hose weight ignored?
Love the videos. Can you do a video showing pulling a vacuum and adding that same reclaimed process r22 back into the same system
I need this video
Thank you for this illustration. Why you don’t use ice to make the process fast? Thanks.
Hi Greg, can you give me the link to the 1/4" x 3/8" x 3/8" tee, the plug pieces for the hoses and the pressure gauge, that would be great, love your videos, thanks
Appion hoses and holders. Appion Y fitting Navac makes one too

What’s the fitting on the filter drier called to attach hoses?
Hey Craig love your videos, but how did you connect 3/8 hoses out of that wye fitting into 1/4 removal tool, can’t find hoses that come like that.?
Excellent video. In this case, the compressor should be in stopped condition?
are you adding liquid to vapor side of tank?
The red outlet from the recovery machine causes technicians to connect the red outlet of the recovery machine to the red liquid port of the recovery tank instead of the vapor. AC service tech, Can you explain what happens when they do that?
Could you please share the link for that Y fitting?
Can you use the same hoses for different refrigerants if you purge them? What about the oils?
Gday. Where can I get the "stem" connector on the blue gauge? Can't seem to find it anywhere.
and should I have left it to keep trying to suck down to hg? like 2 or 4 ? because once I got to 0 it seemed to take alot longer to try to get any lower
Great show wow 4 extra pounds, sounds like someone overcharged that system.
What happens to the oil on recovery? Is the recovery tank going to have oil in it too?
