Great video. You did a great job in explaining how to do everything that you need to know. Keep up the good work.

[@mrnapolean1]

Thanks. For someone whos wanting to get into HVAC and refrigeration repair you provide a lot of information and I really thank you for providing a link to the tools you use.

[@hediervarelamedina987]

It really is an excellent video. and the willingness you have had to explain the entire process in detail and no one gives that information the way you know how to do it. May God bless you and prosper you every day. I admire his vocation for air conditioning, it is clear that he loves what he does. thanks for sharing the knowledge.

[@RajSingh-vd9om]

Thanks for investing in the trade. The trades are extremely short of workers. As a first responder this has allowed me to progress in HVAC on my days off. Manu people don't realize First Responders generally only work 10 days a month, 10 24 hour shifts. That's plenty of drama for me...working HVAC on my off days has saved my sanity. Thanks again.

[@DaveJutsu]

Awesome video ! Great explanation, very clear and concise! Quality stuff ! Keep it up !

[@acservicetechchannel]

Glad you liked it!

[@coreyjackson8378]

Thank for your videos! Much appreciated. I have purchased your book to support you and for reference.

[@acservicetechchannel]

Thats so awesome, thanks!!!

Buenos videos maestro y si ya tengo un par de años con su libro y espero y saque más libros en español para la.comunidad latina qué como yo lo seguimos SALUDOS

[@leinadanielcowboys4033]

That recovery machine did the job very fast.

[@endreszekely8201]

Very informative, however i still dont get the part where every hoses are in place and you open the valve core removal tool and quickly move over to let air out on the tank side. The hoses are closed by the tanks valve so if you open the core removal tools you would still mix air from the hoses into the system. Because refrigerant wouldnt just wait at the core tool for air to get out, or am i missing something?

[@wannabescrapper72]

Hello and thank you for these videos. They are very easy to follow, which is exactly what I am looking for. I have a few questions but I will start with one. Do you have any videos on recovering refrigerant from scrap appliances? We are in a remote northern town and it costs a fortune for our district to empty the fridges, freezers, etc. Once a year a guy comes from 13 hours away and does all of the dumps up here so by the time he gets back we have over 200 sitting around. I am in the middle of taking the ODP/ODS course so that I can drain the units each week or two and scrap them in a timely manner and save a bunch of money for our dump before it becomes too much of a burden and is given to whatever corporation bids on it. Right now it is all free for us but you can bet it won't be if that happens. I'm just trying to find out if I can get away with a $600-$700 unit from Amazon for that ,how you can separate the refrigerants and any other knowledge I can glean. Thank you in advance.

[@anthonylosego]

Also, if you put a JLP3R pressure senor at the spare suction core removal tool side port, you can see the line pressure. It will be higher than at the recovery machine. It has minimal leaking surfaces, so it should not pose any more issue than adding three connections at a Y. In fact, if you count the connections, this jumped method I describe below has 7 of them, and your setup also has 7, but you get the JLP3R as well. Lastly, while removing the cores is great, I found about a 5x speed increase just by putting about half a small bag of ice on top of the tank to take off heat as it builds pressure. R410A will get pretty high pressure even on a cool day. Tanks are rated 400 Psig for normal use and 800 Psig burst pressure. I was pushing about 550 in the shade. Taking about 10 minutes to get to 2lbs recovered. I put the ice on and it went down to 277 Psig (much less scary) and did the other 8lbs in 5 minutes before I hit 0 Psig. I shut it down and waited for the refrigerant to boil off (15 minutes). Went back up to 25 Psig at the lineset. I turned it back on and went to -8 Psig, then did a self-purge. (Brand new AC unit, never operated.... [distributor sent the wrong air handler software model claiming it was a matched set when it was not]) So I was not too worried about gunk or leaks as I vacuum tested this the week before. Plus have a brand new tank, so this is going back into the unit once the right air handler is installed.

[@patrickcaldarone]

Hi @acservicetechchannel, I saw a few comments about the tank exceeding 400psig and getting hot. Can you create a new video and add a subcooler(molecular transducer) between the recovery machine and the tank? I own a subcooler and also created one out of 3/8" soft tubing.

[@geraldolambski412]

Great tutorial, just one question. How many times can i use the filter drier on clean recoverys & should i cap both ends of the dryer between recoverys

[@HVACRTECH-83]

Yes always cap the ends for sure but as far as how many times is a great question which I don't think anyone can give a definite answer to. To be on the safe side I guess you could say to not re use them and get a new one each time but of course no one is going to do that. I put brass flare caps on the ends after I'm done and put them on quickly after I disconnect. Obviously if your recovering a dirty system or a burnout I would not reuse. Maybe Craig has some better input on this

[@pingpong9656]

With car HVAC recovery - you use oil separator to collect oil so you can add lost oil back. Does this not apply here too?

[@MEP.ENGINEERING.WORKS92]

👍

[@Natnat_816]

❤

[@jaimedpcaus1]

How do you know (exactly) that you're not putting air into the tank? I saw that you opened the valve for 5-8 seconds and I wonder if that's the perfect way to purge the line of air. Thank you.

[@oliverpernillo9834]

How often do you replace your filter dryer for your recovery machine ? Thank you.

[@yaboy853]

what filter on the intake is that

[@anellugo2521]

greetings, and why don't they evacuate the lines and the recovery machine, there are non-condensable gases there?

[@joelin5877]

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

[@keithhoward8651]

Question, Would you recommend those Hilmor gauge set up like you have in this video? Because to be honest I really like this whole setup. I am fairly new in the ( HVAC ) field and was just wondering.

[@Holydany]

I prefer the yellowjacket gauge, core remover i think its the Appion's one .. or

[@augustguadagnoli3812]

Always remember to close your service valves before you put the condenser in your truck or your leak oil all over your truck

[@HVACRTECH-83]

You should close the service valves so you don't have residual refrigerant boiling off out of the oil and going into your service van but if the unit is uprite you shouldn't have any oil leaking into your van.

[@ryanmalin]

I could get 60lbs into that jug. The supply shops wont take it, if its overfilled, so make sure not to overfill. The supply allows you to bring that size jug in for recycling filled to 50lbs. How long is the lineset on this system?

[@acservicetechchannel]

Only 12ft. I know two techs on different instances that were driving down the road and their virgin bottle relief went off because the truck was hot. The same thing can happen in a recovery tank if overfilled. It wasnt good at all.

[@HVACRTECH-83]

You should only put 80% of the wc stamped on the tank. This has been the way since day one and has never changed. I too have seen reliefs blow on tanks left in sun which is not allowed either. Relief can pop even if you're not overfilled if left out in sun

[@calledout4437]

But you can recover refrigerant without removing the valve cores? I watched another video with a guy saying you really don't need to remove them.

[@notnecessary7730]

I thought the temp probe was supposed to be near the bottom on the recovery tank. How are you getting an accurate reading from the metal collar?? That doesn't make sense to me

[@anthonylosego]

You can do this with only TWO value core removal tools as well. Just remove one of the cores with the other tool, then attach a hose to the un-cored tool side port to the filter dryer. Then when you remove the cores on the unit, connect a hose between them. The system is higher pressure, so a purge should function the same IF your system is stablilized (equal pressure on both lines).

[@tecniman356]

When i do it, my recovery machine makes the cylinder pressure up to 400 psi. Why is that if it has only 7 lbs inside?

[@drewbush6535]

👋👍

[@frh72]

Best practice would have been evacuating the hoses with a vaccuum pump. You should have one on site anyway. Use a 4 way manifold (LP, HP, Vac, Rec) an open all ports. Set the recovery machine on recover and start the vacuum pump. Once a proper evacuation has been achieved close the Vac port at the manifold. Set the recovery machine knob to close before you open all the valves at the machine and at the tank. Then start the recovery machine and slowly turn the knob to recovery ... the rest of the procedure I would have done the same way as you have explained. Why I am telling you that? There are toxic refrigerants (NH3), flammable ones (propane) or some that reacts with air (HFO) and leads to dangerous degradation products. In this cases a proper yet almost clinical clean technique from the start would be advantageous. Both for you, the environment and the equipment.

[@Silky_boi]

I have a question. So I have a similar setup however my recovery tank pressure shoots up to 400+ PSI and many times and I’ve only recovered 1/3-1/2 of the refrigerant. Is there something I’m missing or doing wrong? I change my inline filter drier regularly and make sure all my hose gaskets are good.

[@122195brandon]

Try putting the hose on the vapor port of the recovery tank and flipping the bottle upside down. Fill it from the bottom basically and still not getting restricted by the dip tube

[@All4ChristNone4me]

Sounds like your tank is getting too hot and your machine is shutting off because of high pressure. So if you haven’t reached 80% tank capacity try putting your tank in a 5 gallon bucket with ice. Or hose it down if tank is too big. Make sure your electronics don’t get wet and make sure your not over filling tank

[@ryanmalin]

you need to put the recovery jug in a trashcan full of ice. The tank's getting too hot and the gas isnt condensing into liquid, youre just pumping hot gas into the cylinder.

[@acservicetechchannel]

It sounds like you have air in the tank and so the pressure is higher than it should be. Check the pressure before use and align to sat temp, thanks!

[@Silky_boi]

@@ryanmalin that would make sense. I’m out here in Southern California, I’ll try that out. Thank you!

[@tuanvo6845]

hi im home owner i want to save money so if you train me like this ,all equipment like this more rhan 1000 dollar so which way is better for us?

[@jenko701]

How to clean your recovery machine so you can use it for different refrigerants.

[@HailoiHailoi]

isn't you should state that the recovery machine has the function of recovery both liquid and vapor into the tank, otherwise liquid alone could damage the compressor of the recovery machine because of liquid?

[@undefined7463]

The point of using digital gauges is to minimize loss and have an accurate zero and pressure reading. It’s important how to use both for sure. The actual manifold with the mechanical gauges is the main “problem”. You could use adapters to use mechanical gauges the same way we use digital gauges. It’s also the point of knowing your tools and knowing when to change the batteries, sort of like knowing when to change out the mechanical gauges or cleaning the internals of the manifold.

[@tbone6354]

Once you recover it do you keep it under your bed. Here in Africa we just let it out. No problem. Its easy, cut the pipe and walk away to go have a beer.

[@acservicetechchannel]

We give it to the distributor and they take it back to the reclaimer.

[@pointblankmatt6580]

Sadly ive met so many “techs” that despite their training, see no point in recovering refrigerant and would rather dump it to save time and energy. just pure laziness but thats a common character trait for a lot of people who view this field as just something you do for a paycheck and not acknowledging the impact we have on the environment with our practices. it also goes to show how poor enforcement there is on proper refrigeration practices

[@whitecannon6434]

Another one that wants more regulations.

[@EliasAtElijah]

You cant always rely on Digital. Im oldskool and i always rely on my manifold as i like to use my brain rather than let equipment do the work for me. If your batteries go flat then will you understand how to use standard manifolds. Most guys ive worked with rely on digital. When their manifold run out and you hand them over a giuge manifold they refuse to use them.

[@acservicetechchannel]

Gotta know how to use compound gauges for sure! Always have them in the truck as well! i trach my students with compounds first before they move to digital. its like driving a stick shift car. If you know how to drive a atick shift, then you will know auto too, thanks!

[@EliasAtElijah]

@@acservicetechchannel Great Video!

[@alanmainwaring1830]

Good point about Digital measuring devices, just because Digital may have high resolution does not mean the instrument can actually read to that level. Of course, any measuring instrument be it analogue or digital can be faulty without you knowing it.

[@boby115]

@@acservicetechchannel, good analogy👍. Just an FYI, if you want to recover a little faster , turn the recovery tank upside down and recover into the top of the tank (which is now the bottom of the tank) .This method eliminates the use of the restricted tank straw.

[@leoschneider3570]

I agree, it’s the same for me, also digital gear is a lot more expensive, (even though you easily earn that back, but still)

[@ga6386ga]

what, this is a real, real bad way to do recovery. what happens if there is pressure difference between connection? Answerer: air in house will be pushed into system from higher pressure to lower pressure. Only air in hose from T to tank will be removed, rest wil be recovered to tank. This way can only be done if you have 100% same pressure in conection.

[@dan4091]

He said system was off for awhile

[@ga6386ga]

@@dan4091 yes, he mention that, but do that mean pressure is equal? What do temperature difference do with pressure? In an ideal situation where everything have same temperature and where stoped for a long time yes then ok, pressure likly be same. But as a teatching video this is bad, people will do this in situation where pressure is diferent and contaminated system whit air.

[@acservicetechchannel]

Thanks for bringing up the point! This system has been off for a little bit over a month.
