Its like having two hvac super heros together
these 2 guys have mad skills
@@chrisleon7312 you win horrible pun troll of the year.
:)
Word up ⬆️
Legendary techs 🔥
LOL, I worked in Death Valley as a HVAC tech at Furnace Creek Resort. You can throw every Refrigerant rule of thumbs out the window. A average day was 120 degrees. Lots of PTacs, and Swamp coolers there. We did have 2 chillers. I worked on everything window units, Ptacs, coolers, freezers, chillers, A/C units, Kitchen equipment sewer plant, . Great place to work. Resort furnished free housing, free health insurance, 2 free meals a day, a golf cart to run around in even for personal use, free access to the golf course. Weight room, and swimming pool. Lived right on the resort 2 minutes to work every day. The only down side was everyone knew your business.
2 titans of the HVAC industry in one video. COOOOOL!!!!!
I'm really glad that you enjoyed it!
Beautiful to see two great teachers working together and explaining this process in great detail helped me a lot in process getting of getting my epa 608 certifications
WHAT? My two favorite HVAC channels combined. Thank You. #hvac #recovery #enjoylife
Glad you enjoyed it!!!
Thanks Craig! This was a lot of fun. It's great to be on my favorite CZcams channel even if just for a moment.
Absolutely fun!
U2 are very very COOL ..... happy to see u work together like this .....NICE .....
Omg I never thought that I can see you 2 of the best technicians together giving us a great class 👏 🙌
Great respect for these two guys, in my humble opinion you are the two super stars in this trade.
Thank you for your time and effort.
Much appreciated!
This is fucking epic and legendary at the same time. 2 best HVAC instructors around.
Wow 👌 👏 👍 there's no better explanation than that...
Thanks for all of those tips! they might be small but they make a huge impact in our trade....
HVAC TECH FOR LIFE! Thank you... for sure two of the best teachers there are...
These two guys are awesome and filled with knowledge
24 minutes of talking recovery tanks! That’s a lot informations! Thank you for both you! You guys are great men.
Glad that you enjoyed the video, thanks!
what an interesting series of videos on both channels , thank you for sharing
Glad you enjoyed it
Just got my universal license. You guys teach amazing 💪🏽
Nice to see you two team up.........Bryan I enjoy your webinars an podcasts, Craig you make some of the best detailed videos I've seen out there......It's great to see other individuals dedicated to the trade......Hat's off to ya fellows.......Thx, John
Thanks a lot eracismm
Thanks for the education, I'm halfway through 9 month HVAC course , I learn more watching your videos. I did purchase your training, study work books
Ron, I always tell people, your instructors are laying the ground work and these videos help summerize the content, thanks a lot!!!
Also I work on a lot of large VRF systems that usually have over 80lbs of R410A. I was having issues on warmer days recovering the refrigerant and struggling with taking the cans in and out of ice water and running back and forth to an ice machine. I found that the CPS MT69 Molecular Transformator actually works very well. Probably not needed for small systems but in this case no joke cut my recover times in 1/2. Still need the ice and water but dont need to move the can back and forth to a scale and it speed things up alot as it cools and condenses the gases to liquid before it gets to the recover can keeping the can nice and cool through the whole process.
I had a really great time with Bryan down in Florida! He really knows his stuff and glad to have the opportunity to work with him!! Subscribe to his channel and check out his website www.hvacrschool.com
what happens if you induce air in the tank, or lets say nitrogen. what could go wrong or what problem could it cause? thank you!
U2 are very COOL ( no pun intended ) ....very nice to see you collaborating together on this video....
Thank you both .....
Awesome video. I have learned a lot from you two guys. Thanks again
Thanks for watching!
Thanks for answering a question I recently came across.
Glad it helped Rick!
How to calculate cylinder capacity:
Find the cylinder volume first. Water capacity (WC) divided by density of water (DW) = Cylinder volume (CV). (Use 62.4 for the density of water).
Once you get the cylinder volume you'll need to find the liquid density of whatever refrigerant you're going to recover. Use the liquid density at 130 deg F. You can find it online by typing in Thermodynamic properties of R-134, R-410 or whatever refrigerent that suits your fancy. Store that number in your phone so you'll never have to look it up again.
Now take the numbers above and multiply them: (CV x liquid density x .80) + Tare Weight (TW) = Cylinder capacity
Of course you can just use an online calculator to do the same thing but now you know how to do it the manual way.
Great teamwork guys
This was awesome guys!
Wow amazing explanation
Thanks to you both!
Glad to help!
Two big hero HVAC
Thank you for your kind words! Bryan is awesome. Also make sure to check out Ty Branaman's channel as well, thanks!
Great explanation of the process
Agree..
As I said in the last video. You two guys are the best. 👍👍
Thank you very much AddyBra, glad you enjoyed it!
Agree..
You guys have great videos.Thanks.😜
Thanks for watching!
You two are a hell of a collaboration for the hvacr service industry 👏 should be required viewing for new techs
Bro you don't even know what a receiver is. Aren't you a new tech?
I I am really glad that it means so much! I appreciate it!
Nice video dude, thanks for sharing
Glad you enjoyed it!
Great video. Thanks
Glad you liked it!
Agree..
cool learning from both pros
Good tips for us newbs.
My HVac school uses your materials! In Los Angeles/ San Diego area! Shout out Mr. Gutierrez class.
Wish I knew you guys were in nj! I'd break something in our ac just for you ;) or buy beers w.e works. No jokes, thank you and the teams for doing these videos.
excellent
Many many thanks
muy bueno !
Two chiefs will like it ! good info thanks
Great Guys !!
Also , is good to not use the same filter dryer for different types of refrigerants- Always use one filter dryer for one type of refrigerant only
I know a lot of Tech's have recovery tanks that Moses' may have use on Mt Sinai, but the DOT law is recovery tanks have to Hydro-tested every 5 years same for LP tanks on the BBQ, 10 years for high pressure tanks like oxygen. It's a Federal law
THANKS FOR THE INFO : I had no idea MOSES had a tank on MT. SINAI .......

I would like to share a tip I may have invented (but probably not) since I haven't seen it anywhere else. When deburring copper pipe that is already set in place, most people caution against getting the tiny bits of copper down in the line. They try to bend the pipe down and shake the bits out, not much fun with 7/8, or ineffectively blow out with nitrogen. But here's the fool proof way for deburring pipe in ANY position.
Before deburring, and after checking that no pieces of copper from cutting remain, roll up a wad of paper towel or rag, shove down into the pipe about 1/2 inch. Make sure your deburring tool has enough room between the wad of towel or rag to operate and deburr. When done, just pull out the wad and the deburring shavings come out with it! Use needle nose pliers or tweezers and the wad won't unravel and will stick tight to the pipe wall.. Especially useful on vertical pipe that needs deburring and prevents the chips from falling straight down the pipe.
Now that's a good tip. I'm going to head out this weekend to harbor freight and get a couple pairs of tweezers if they have them. Good tip
Remember even brand new tanks the valve seal packing on the valves sometimes leak under deep vacuum when you’re trying to pull a deep vacuum just like a king valve on refrigeration is notorious for leaking under vacuum.
Add a little nylon or silicone grease to the valve stem as you’re opening up the valve and when pulling a vacuum it’ll pull down into the shaft towards the packing giving you the ability to pull a complete deep dry vacuum.
And you can weigh the bucket of ice water with your tank in it on top of the scale because the water weight will not increase or decrease because the ice is melting it stays the same.
And on record-breaking hot days on the roof and the water is available dry ice is cheap and easy available where I am it has an amazing ability to SuperCool your recovery tank even on 110° day where the rooftop is 120° in dry ice your recovery machine will perform miracles on speed of recovery.
Make a video on how to reinstall it into the system from the recovery tank
Always check the DOT marking on the cylinder to make sure it's rated for R-410. DOT marking should be 4BA400 or 4BW400. I've found cylinders that had R-410 in it but the cylinder wasn't rated for it. One ounce of R-410 in a cylinder is like having a full cylinder of refrigerant. Luckily I found the mistake and transferred the refrigerant to another cylinder that was rated for it or someone would have had a bad day if the relief valve failed to function.
Having not read the comments previous to this, I wanted to add that I personally have found that using the side of the recovery tank valve that is considered the high side for recovery can cause the refrigerant to heat up due to the excess friction caused by the inner tube.
I hope I said that right.
hi thanks for all important information i have a question if i pull refrigerant from recovery tank to a system should i do it from hi or low valve?
This is an area I am not familiar with. What do you do with the old refrigerant ? Can it be cleaned and dried? I have bought my second book on this area. There is so much to learn in this area these guys are incredibly gifted.
I have a question, you say you can turn on the fan from the thermostat inside the house to help boil off any refrigerant left in the evaporator, at which point can you use this awesome tip, when you're pulling liquid from the liquid line or when you're pulling vapor from the suction line.
I’ve watched every video
You get and thing good out of them? Are you a service tech? Craigs ac service tech book is worth the money the posters are great references also
Yes I’m a new technician watching your videos! I’m from Central Florida
Thank you very much and that's awesome to hear!
Oh Yeah! Craig ...we're gonna go ahead.... Migliacco
两位都是大神级别的技术人员
if the unit is running not a burnout you can use the compressor to recover the charge then use the recovery machine to get what the unit couldnt pull due to low pressure cutoff.
if you are scrapping a unit you could probably safely bypass the low pressure cutoff because it wont matter too much if you start to damage the compressor.
if you are working on units at the shop you can put the recovery tank in the freezer to cool it to make it recover better.
i heard somewhere if you do get air in the tank you can let the tank sit for 24 hours then vent the tank slowly until the pressure stabilizes to purge air
often compressor manufacturers may state virgin refrigerant must be used to maintain warranty but if you are not replacing the compressor you can probably reuse the old refrigerant unless it is contaminated
i think why people uses small tanks is because of the 50 pound rule.
if you vent a 30 pound tank the epa may not do much for investigation but if you vent a 50 pound tank they will jump off their butts and do something immediately.
WONDERFUL INFO : THANKS ..... from the old man who has no money , but is very interested in ALL THINGS TRADE AND TECHNICAL ( a retired frame carpenter ) .....
When recovering or changing a system with a solenoid valve, do u recommend a solenoid magnet or could u keep evaporator circuit energized so valve remains open ? Thanks for sharing your experience n knowledge
Good question.......
so if there's a leak on the system and we have to recover the refrigerant we have to come close to zero psi in order to not let air in into the tank right? then are we able to open the system to star the repairs or what do we have to do right before opening the system?
so what you will do with recovery refrigerant? you can use it again to charge? If not, how you get red of the recovered old refrigerant? Can you explain? Thanks
This is more a question than comment, I live in a very remote part of the country where its been near impossible to get service on mini splits. As a result I have been forced to do my own installs and service. Between my self and others around here I have installed and help service about 30 Mini's. Can I recover and reuse the 410a and bring the systems back by adding the short fall from the recovery process
What about if the bein replace is good to use same refrigerant even if the unit has a leak
Fun fact! The dip tube is not always on the liquid side it depends on the tank manufacturer. Some takes are designed to be turned upside down where others are designed to be right side up. I always remove the tank valve to verify and yea I have seen the dip tube on the vapor side. Wish all things were standard but not in this biz. I had this argument with another tec so we removed the valves from a few cans and his mind was blowen just as mine was when I first found out. How long have I been doing this wrong lol. We have a lot of older tanks which may be the issue though its always wise to read the literature and verify!!
You are correct sir. Good comment for bringing up the newer tech's.
Agree..
Steve Lav needs to make a cameo.
I bought an old promax RG5410hp recovery machine. The two gauges on it said 410a. Can I use this machine to recover different refrigerant,
What if the indoor fan motor doesn't work. What is the best way to pull the refrigerant out of the unit. Do I take it out on the low side as a vapor but still cut on my condenser?
I have a question ? What proper way for recovery refrigerant on Multi systems? Thanks
So run the fan during recovery AND Also run during evacuating with the pump?
I want to see an HVAC " fight"between you guys!
who ARE you ??????? JOE ROGAN OR DANA WHITE ????? .....no fight over important technical stuff !!!!!
But I still like NICK DIAZ AND JOHN BONE JONES ..........!!!
Thumbs up
so if your doing a condenser repair job like a coil or filter drier. Is it suggested to charge the customer for all the refrigerant? So if your replacing a filter drier and the unit takes 12 pounds are you supposed to charge the drier replacement plus 12 pounds of refrigerant? Because you dont want to just use 12 pounds of your refrigerant for free but at the same time you dont want to charge the customer a ton of money
I believe I’ve accidentally mixed different freons with the same tank. Is there any way I can empty the tanks?
In Thailand the gases are recovered to Budha. I guess many countries can ignore the rules and the ones that follow at least make some difference.
I am a CATHOLIC , NON- PRACTICING , with a very good knowledge of others .....and I am fairly certain that the refrigerants RECOVERED TO BUDDHA , as you say , will cause no problem either ......
refrigerant r123 in trane centrifugal chiller could be recovered 100 percent?
What is nton and pton on trane chiller?
Is there a way to clean or flush a recovery tank?
This is like watching the justice league Batman talking to Super Man 😂
I am glad you didn't say batman and robin!!! ha ha
Do y have work book for r290 and r600 …or program r290and r600
Can I use the same hoses that I use for a vacuum to do recovery or should I have one set of hoses for vacuum and another set for recovery?
SOMEBODY ...THAT AINT ME ... said to absolutely use DIFFERENT HOSES ....can't quite remember my source ........
Just takena sawzall to the lines only sprays out for a little
We follow the EPA 608 standards which has a fine attached.
Which recovery machine is better: Feildpeice MR45, or NAVAC NRDD??? Also have you ever used or seen a NAVAC NRRD (Analog Recovery Machine) used and if so would you compare it to either the MR45 or NRDD?
Go with your budget, i use the MR45
Good question, hopefully the two of you in the video will respond...
Are you turning heat on also while recovering or only the fan?
Just fan most of the time.
do we required rubbing ice on cylinder when recovering R22 using recovery machine ?
Its not required unless there is air in the system or the pressure in the tank is high, thanks!
@@acservicetechchannel you mean to say. Its not required when recovering liquid refrigerant.
Where can I get hvac training?
7:45 you're trying to say "prime it with the target gas at the workshop to say 5psi. Right?
Good idea so u dont have to waste time on job evacuating reclaim tank but also you will have to keep track of how much gas you used to get that 5 psi im guessing like 6 oz for 50# tank
Nathan, yes certainly you can do that or vacuum the tank on site. Either way is good, thanks!
I greatly prefer at the workshop, since option 2 on site you have the unlabelled tank with ~25psi of gas, then the guessing game : is it nitrogen or the target gas? Sniff Sniff? Ok vacuum it for half n hour
What are those Schrader valve removal hose connections called?
valve core removal tools vcrt's
THANKS 2 ...
Why pull a vacuum on the tank before recovery? Does not the tank come at 500 microns or below?
The tank comes from the distributer pressurized with nitrogen usually.
Which is a faster recovery, liquid or vapor?
Liquid is faster but often we pull saturated refrigerant from both sides.
Awesome, thanks!
If a system has a leak then it won’t matter reclaiming below zero as that gas can’t go back in the system as the new gas should be charged as a whole.
Had a tank go off on me
Love your videos but i don't agree with the point you made about pulling the system to 0bar. If you're not re-using the refrigerant then why does it matter if pull air in through the leak points? I've personally got the system pressure down to 0bar but still pulled an additional 2/3kgs out of a system below atmospheric. obviously that refrigerant was stuck in the accumulator frozen up.
Josh we meant that after the recovery machine is off, it shouldn't rise above 0 psig. I mentioned in the video that I like to pull below 0psig as long as there are no leaks and I like to heat the system while recovering if possible.
I did not know it is technically not allowed to reuse the old.
Even more i didnt know that the tanks are not always cleaned.
Cant reuse if the refrigerant is from a different owners hvac system, thanks!
Man I didn’t know you were from jersey sheesh can you train me lol
If someone has r22 they cannot afford vergin Freon just for a small repair
I am thinking of PARTING OUT MY 2005 HONDA CRV - XL : DOES the fact that my HONDA NEITHER CRANKS , NOR START have anything to do with RECOVERY .... and approximately how much should I be prepared to pay ??????
THANK BOTH OF YOU TREMENDOUSLY : and I have ZERO INCOME .... but my wife does ....
I FAILED TO MENTION THAT I AM MORE PROUDER THAN BEELZEBUB HIMSELF .........
What happens with mixed tanks?
Wtf do you think happens?
Some facilities will reject them or charge you extra to reclaim it.
Send your mixed gas to Jahmal he separates it
@@WillieMakeit exactly! Lol
Its considered contaminated with blended refrigerat.
Too bad someone doesn't invent a recovery bottle like a thermos with a double layer tank with a vacuum in-between the layers because temperature can't be transferred through a vacuum and heat wouldn't affect is as bad. Also have a temperature gauge in each tank for an accurate measurement.
Actually that would increase the problem with high pressure and high temperature in your recovery tank.
Do you want to convey that heat away from the recovery tank because it gets hot from the heat of compression that is produced inside your recovery machine.
This is why they were mentioning running cold water or buckets of ice to cool down the recovery tank.
Having a thermos bottle recovery tank would just keep all the heat inside the tank increasing the pressure as the temperature increases
Can you do a yelloew hose recovery into a 5 gallon bucket of water??? I say no.
Once you have recovered it do you keep it under your bed. Here we just let it go. There's no point in keeping old gas.
4:04 - There could also be less than 30lbs of refrigerant in this example if there were some oil in the bottom of the recovery tank.
Very thorough.....Central Java, Indonesia Present
When going to put your videos in español?
What is español?......Central Java, Indonesia Present
Only because I'm shameless. But to really have a functioning system you need to mimic the current recycling system ie monetize the waste via a deposit. Techs return tanks with 20 psi and get 5$
Lol! Soup to nuts?!
Ha ha, thanks Eric!
