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.

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 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

[@alanmainwaring1830]

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.

[@themrmoy40]

muy bueno !

[@Kevin-ib4gv]

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.

[@ABCJKE]

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

[@otiskirkland168]

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.

[@mojo9288]

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.

[@MrGabriel1973]

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?

[@fromanabe8639]

Oh Yeah! Craig ...we're gonna go ahead.... Migliacco

[@coldfinger459sub0]

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.

[@mojo9288]

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.

[@wayneyates9264]

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.

[@shine-cg9uf]

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

[@mbahcarrier1629]

Good question.......

[@jay863betta]

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

[@acservicetechchannel]

Thank you very much and that's awesome to hear!

[@JesusRomero-lp6zt]

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?

[@ejonesss]

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.

[@gregscheyd4131]

[@khadijahussain1938]

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

[@taylerellis378]

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!!

[@ABCJKE]

You are correct sir. Good comment for bringing up the newer tech's.

[@mbahcarrier1629]

[@user-gy5nu9mb3p]

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

[@ganeshsurujlall4478]

I bought an old promax RG5410hp recovery machine. The two gauges on it said 410a. Can I use this machine to recover different refrigerant,

[@robertsneed7689]

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?

[@miguelsantoyo2484]

What about if the bein replace is good to use same refrigerant even if the unit has a leak

[@airlogitecQ-electrical]

[@ReelGuyTv]

Steve Lav needs to make a cameo.

[@maxwellla2104]

I believe I’ve accidentally mixed different freons with the same tank. Is there any way I can empty the tanks?

[@exclusive_148]

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

[@Froggability]

7:45 you're trying to say "prime it with the target gas at the workshop to say 5psi. Right?

[@Holop88]

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

[@acservicetechchannel]

Nathan, yes certainly you can do that or vacuum the tank on site. Either way is good, thanks!

[@Froggability]

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

[@KrunalBhatti]

do we required rubbing ice on cylinder when recovering R22 using recovery machine ?

[@acservicetechchannel]

Its not required unless there is air in the system or the pressure in the tank is high, thanks!

[@youngjedi5599]

Why pull a vacuum on the tank before recovery? Does not the tank come at 500 microns or below?

[@acservicetechchannel]

The tank comes from the distributer pressurized with nitrogen usually.

[@johnnyjackpots505]

Which is a faster recovery, liquid or vapor?

[@acservicetechchannel]

Liquid is faster but often we pull saturated refrigerant from both sides.

[@johnnyjackpots505]

Awesome, thanks!

[@joshwest9364]

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.

[@acservicetechchannel]

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.

[@Fox9582]

This is like watching the justice league Batman talking to Super Man 😂

[@acservicetechchannel]

[@WillieMakeit]

Its considered contaminated with blended refrigerat.

[@robertcarter1889]

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.

[@davidmarshall9160]

Can you do a yelloew hose recovery into a 5 gallon bucket of water??? I say no.

[@clevc112]

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.

[@coldfinger459sub0]

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

[@tbone6354]

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.

[@AntonioGarcia-jv6rn]

When going to put your videos in español?
