- There are some great times in the HVAC industry when you see a group of people that you might not expect to work together reach new heights that they could have never achieved independently. That is exactly what happened when Fieldpiece, AccuTools, and measureQuick each independently launched products that turned into a combination of tools that will disrupt the way evacuation is done in the HVAC/R industry today.

Gotta love Fieldpiece. Making HVAC service unaffordable, one tool at a time.
Just tossing this out there.
I am not an hvac technician and the amount of money that I saved on paying for a "professional" installation while buying EVERY high end Fieldpiece product (which I still havent opened yet honestly...) was attainable while still putting around a grand in my own pocket over what the insane quotes were for people showing up with hoses and pumps.
Perhaps you may want to re-calculate your business costs and quote jobs accordingly?
SMH.
I am a HVAC technician and man do I not like fieldpiece tools I think there are more better tools out there for the price and more reliable
Testos NAVAC stuff like that but down side is something’s can be expensive
I’ve got the newer one and I love it
Just bought the 6cfm model and I'm not even a tech. I'm just sick of paying $500+ an hour for crap job. So I have been watching everything I can and starting to piece together HVAC tools. Already took and passed my EPA cert. Im from the trades but HVAC was the one thing I never really messed with. That's over. Here in Florida I haven't seen one tech flow nitro while brazing. The system I bought just 7 years ago the guy used no nitro and my TXV went down a couple weeks later and cost me an extra $350 to swap it out and it was most likely the installers fault. Now I just replaced the coil last week which I suspect was also the result of bad install. $1,550 just labor as it was still under warranty. He didnt even check sub cooling on TXV system just slapped some gauges on and said something like 100/300 all good... Next purchase is the fieldpiece joblink probe kit FPJK-MQ. However, next time this system goes down its all coming out and getting replaced with a complete muilti zone ceiling cassette mini split system. Here in Florida they not only thought it would be a good idea to take all the worst possible HVAC practices and instead of just picking one or two to use they decided to use them all. We will start with not only putting the air handler in an unconditioned space so the cabinet will sweat like crazy but we will also locate it in the garage so it has the possibility to suck dangerous fumes and spread them through your home, We will ignore all the recommended condensate line rules and use no trap and run the line under the slab so the water can just sit there and stagnate and get all sludgy so you need to blow it out every month. Then we we route all the duct work through the attic where temps can easily reach 150-170°, but dont worry to combat that we are going to use fiberglass ducts to try and insulate all that nice cold air you pay to condition from that extreme heat, Sure there's a cancer warning label on the fiber duct box but pay no never mind to that as we blow fiberglass particles into your air you breath 24/7, Oh and did I mention most roofs will be very shallow 4/12 pitch so you have to be 5'4 and 90 pounds to even be able to have a chance of maneuvering in the attic so forget about doing any type of service to the ducts, but wait there's more instead of running returns to every room we will just use one large return so you will have the worst air flow possible. I don't think you could come up with a worse system if you tried. Good job Florida you managed to create the worst possible scenario for HVAC systems. I am planning on getting all fieldpiece equipment can you buy cheaper stuff? yep, but from what I have seen they look like they have a well thought out system and I prefer the buy once, cry once approach to tool buying. Best of luck I hope business picks up for you.
I wish I was better informed 7 years ago about mini spits as they solve every issue. Plus it provides a lot of redundancy having multiple indoor units and 2 outdoor condensers if one part goes down you still have some air. In S. Florida AC is not an option when it goes down you need it fixed and fixed fast. With a traditional split system if either of the 2 components stop working you have no air and that is a good enough reason to go mini splits alone IMO.
Great video Jim, thanks for sharing.
Got the VP85 from TTT last week and the Accutools hoses just went in stock at TTT can’t wait!
just ordered new vacuum pump and tru blue hoses and core tools customers are paying for it not me...thanks jim learn alot from you.
I am starting to love fieldpiece equipment
Now After I see this I can say that the FP vacuum pump is Jim Bergman certified and the FP pass the test.
Thanks Jim. 😎
It is a very solid pump and works great with the TruBlu Hoses.
Thanks for watching Jose.

Thank you this is very helpful as I have the company that installed mine coming back out to make sure they sealed it right. So now I know how they will be doing it!
This is absolutely amazing. Like most other nice things this most cost an arm and a leg and a kidney for shipping!
Very cool vacuum and nice video.
Dang, Jim. That's quite a setup. I may have to look at that offer in the email.....

Fieldpiece is the Chrysler of HVAC; well thought out, good placement, clever, and built like crap. Remember the blue clamp on temp clamps? They broke like glass. Nipples on your manometer? Buy extras even though you've never bought one. Fieldpiece barbed nipples were plastic, everyone else metal, forever. Testo, Yellow Jacket, Robinair imo. EDIT: Of you're willing to pay $500 for hoses after buying Fieldpiece, I'd like to talk to you about an investment idea.
At the 6:45 mark you mentioned about evacuating too fast and causing water molecules to freeze. I also share that mindset. I recall hearing Bryan from HVAC school saying along the lines that it's a myth that you can freeze water by evacuating too fast. I believe it's possible but that depends on conditions of the system. Sometimes I don't know the conditions or previous history of some equipment I work on and I can't trust that good refrigeration practices were used while it was being serviced on. Or I'd get a no cooling call for a unit on Monday that probably went down the weekend before to find that it's flat on gas. It could've rained in that time period or just a damp early morning could contaminate the system. I always pull a slow vacuum at start by choking the valve a bit then just open it all the way after seeing that I'm pulling down.
You really need standing water for it to freeze. That would be a lot more than normal.
Don't worry about it unless you are near freezing temps. Even then, you will freeze no matter what.
you just sold it. awesome
Will my lender recognize the Fieldpiece logo, or will I need a supplimental brochure when I apply for a second mortgage to buy this unit?

Jim, I have watched all your videos you are the man! Any way I can connect with you I am intrigued by your check charge without gauges method. I work for a very a large mechanical contractor and would love to implement this method.
Jim@measurequick.com
I have purchased a set of these and they are fantastic. quick question, over the years of pulling really good vacuums on systems ive noticed that in some cases you don't need to add refrigerant to a system that lets say has a 25ft line set when installing a new condenser (that comes precharged with refrigerant up to 15 ft of lineset) is there any correlation between the 2 factors?
Eddie Sellers no correlation, my guess is the factory charge is not spot on.
In the real world.... residential stuff...you will pull a cigarette vaccum because you gotta be somewhere else and the boss man is blowing your phone up
Or lunch vacuum.
We use to do lunch vacuumes back in my residential days
You cant have 3 lunches in 1 day
That is very good 👍
I used the system today for the first time. Fieldpiece vacuum and Trublue hoses. I pull vacuum on whole system due to evap coil change, and I could not get it to pull past 1400 microns. Did pressure test and it held. Swept with nitrogen and pulled vacuum again. Still would drop below 1400. All the fittings were tight as far as I could tell. This is my only worry is too many connections.
The connections are almost never the issue. Follow this process to check the rig. First test the ultimate pull down of the pump, attaching a gauge to the 1/4” port by itself. It should go under 25 microns. Next, hook the hoses up one at a time to your pump with the gauge on the end of the hose connection You can add the core tool too and test that at the same time. That said, if you close the core tool you will see a sharp rise as the volume is too small to hold a deep vacuum. The hose and core tool should quickly pull below 100 microns, and 10-20 minutes (if you want to test them that long) they should be within 20 microns of the ultimate pull down of the pump. Really if they quickly go below 100 you can be assured they are tight. It is impossible to pull that low on a leaking hose.
That vacuum was pulled yesterday it was pulled so fast.
Is there any advantage to hooking up a 3rd hose? Would it make a noticeable difference when pulling a vacuum?
The reason I ask is because one of kits that are sold has 3 hoses and the other only has 2. Was wondering why have the additional hose?
Maybe is too late to answer to your question and maybe you already know the answer haha but lets do it for newer techs watching the comments the third hose its more often use on commercial refrigeration when you have multiple ports that you can use for a faster vacuum so you avoid doing overnight vacuums!! 👍

The treatment might be as simple as a change of diet to lower LDL and raise HDL which will slowly clear out blockages in your arteries. It can only help to eliminate sugar and all bakery/flour products including pasta and cold breakfast cereal from your menu.

Jim those hoses are for 2,500 ton York chillers!
No wonder it pulled the system down to 150 microns in less than five minutes.

What brand are you using for schrader removal tool?
I'd Just like to ask isn't this the entire purpose of Triple evacuation technique?Are you telling me I can skip the Manufacturers recommend 3E and get the same longevity and result through your equipment, you guaranteed this?
Question. When it comes to leak checking a system, which method is more reliable.
1. Pull a vacuum and see if it passes the decay test.
2. Evacuate the system, then pressurize it with nitrogen to the specified pressures and then see if it holds pressure for a specified period of time?
If you had to choose only one of those strictly for leak check purposes, which one would you prefer and why?
pressure test with nitrogen
Im new to this HVAC world but I will add that finding a small leak under vacuum is almost impossible ( I built a vacuum pump from an old compressor and a vacuum lifter for a cnc to move sheet goods around the pump was connected through a lot of tubing and valves and it had a leak I could not find it under vacuum. So, I filled the system with compressed air and used some soapy water and found the leak right away) but if you have it pressurized with nitro you can use a bubble leak detector which would make it a lot easier to find where the leak is. So based on that past experience I would go with pressurized nitrogen for leak detection. Pulling the vacuum is more about decontaminating the system and removing all moisture which is the biggest AC system killer. Its just the last step before charging so you already have everything setup so you might as well do one last test before charging all that expensive refrigerant but as long as you did your pressure test right the decay test should be good too. Also by using nitrogen first you will have the added benefit of having already displaced most of the moist ambient air with a good inert gas. However like I said I am new and 100% you tube trained thus far so take my opinion for what its worth.
How do you isolate the micron gauge on the VCRT after pulling a vacuum and before breaking the vacuum?
Do you connect another VCRT to the micron gauge to valve it off before breaking the vacuum with refrigerant? I don't want to contaminate the micron/vacuum gauge every time I pull a vacuum.
good question, should probably use another ball valve
or since this is a new system i suppose he could just open the service valves and subcool the charge
Most vacuum gauges cannot take a pressure hit.
Do you sell a TruBlu Manifold Gauge set for refrigeration?
What device is sending the bluetooth info to your pad? The micron gauge or does that pump have built in bluetooth
The micron gauge. That is the BluVac Pro
Why you leave the vacuum pump running during decay test
did you test this unit with information provided from the manufacture?
I am not sure what you are asking, the video was of the evacuation. The tech adjusted the charge and airflow after that.
How will the Schrader cores be reinstated to the service valves without exposing the system to moisture ingress? And how do you break the vacuum pressure with refrigerant?
I was thinking the same thing. He should of used an Appion schrader core removal tool.
@@chobe69 absolutely, a must have piece of kit for any Tech.
This video was gangster
What do you do to keep refrigerant from going into the micron gauge? Or is this not a problem?
On the Accutools gauge, it is not a problem. It will handle up to 1000 psi. The key thing is to open up the suction side first, with a gauge on the liquid line. That will only pressurize the gauge with refrigerant and not contaminated with oil. When the compressor starts, the oil will end up back in the sump almost immediately.
Where’s the link to that same exact hose kit
Awesome video! I'm currently going thru HVAC school and this video helped me out greatly... Jim can you provide me with the type of pump and all accessories?? God Bless
Hi Jesse, we used a Fieldpiece 8cfm vacuum pump, Accutools TruBlu hoses - Advanced kit case, and the Accutools BluVac Pro gauge.
hey Jim, new on here. now that you have had the pump for some time now, how has it held up? would be good to hear some people have good reviews, i have only seen on youtube that it has problems over time, thanks.
We have had no issues, and I have not heard of many if any issues with the pump.
I’ve had mine since January and haven’t had any problems
Where does the drained oil go? Is there a special compartment for that? Thank you

@@drodriguez394 no need to be that rude
After one year of ownership the vacuum pump will no longer start.
It was one of the best vacuum pump I ever own
If oil were to get into the tru blue hoses, what’s the best way to clean them?
Eddie Sellers Take the fittings off, put a little bit of solvent or 95% alcohol into the hose, slosh it around and pour it out. Then put the hose on the vacuum pump for 15-30 minutes to dry it back out.
Knee pads brother ! “It’s not a race its a marathon”
As a wise tech once told me, gotta take care of you for the long haul 🤙
Time is money. The more time you spend on your knees the less time you are getting to your next paying job. I don't care to stand around watching a slow system pull down a vacuum. I only do a single hose vacuum with a vacuum gauge on the liquid line and it pulls down nearly as fast.
Does anyone know if the TruBlu hoses are available in the U.K?
Same set up I can get mine down to 43
Are those the 2 m hoses or one and a half?
1 meter.
Most vacuum gauges cannot take a pressure hit. How do you isolate the gauge when you dump the charge ??!
Kevin Lausier not required, the BluVac can handle 1000 psi.
1.56 vengono tolte le valvole a spillo, probabilmente per avere più portata e meno perdite di carico. Fin qui tutto bene, ma poi con le tubazioni in vuoto come vengono rimontate senza perdere il vuoto? Grazie
a question Jim. I understand that an oversized vacuum pump in cfm, to be used in a small equipment makes a sudden vacuum, causing the freezing of moisture trapped in the system. It is suggested that the cfm of the vacuum pump capacity is capable of effectively evacuating 7 tons of equipment capacity. Correct me if I'm wrong.
Moisture is not common in A/C systems, and should not be of too much concern. Additionally, in order for the water to freeze, it has to cool the surrounding piping to the freezing temperature. This again is not typical. That pump is realistically good for up to 20+ tons. It is just fine, but a bit oversized for a residential system.
Look at this video ruclips.net/video/JsnQeUSuUMU/видео.html
Robinair makes a good vacuum pump that doesn’t require a second mortgage it’s like 230$ 2 stage vacuum pump
The Fieldpiece I got was only 350.
How's that vaccum pump perform in cold weather, do you have to warm it up before use?
It has a cold build in cold weather start assist through a D/C motor profile. It works very well in the cold.

TruTech Tools or many of the Johnstone and Habegger stores carry it.
How do you take your hoses off without introducing air back into the system when you have removed the shrader cores?
Steven Leiting Once the evacuation is completed, you will then “break” the vacuum with the refrigerant charge that was supplied inside the outdoor unit from the factory.
@@coleyhicks8524 not if there Schrader cores we're removed per the video. He should if used a Appion Schrader Core Removal tool
Nick Pappas what
@@coleyhicks8524 in the video, the gentleman removes the Schrader cores to speed up the evacuation process. This is common when dealing with commercial applications like VRF systems. When you remove a Schrader core it has to be removed with a Schrader core remover so that when the evacuation process is over you can place the Schrader core back in with your hoses still connected. Therefore allowing you to break the vacuum with the refrigerant.
Nick Pappas no shit ?
What software are you using with the VP.

No Nylog? Is that not the preferred method now or does this company not endorse it?
For the main o-rings it is not needed, and it is a bit of a dirt magnet. Remember, it is an assembly lubricant, not a sealant. it does not help with getting the vacuum any deeper. We still love the stuff, just not for the use with TruBlu hoses. It is simply not needed.
Is that the old line set?
Wayne Miles yes, About 100 foot of it, when you consider the up-and-down. It was an R22 conversion to 410a. The line set was flushed and pressure tested before I got there.

First phrase foreigners know how to say when learning English is "we're gonna go ahead and..."
Hey Jim.
What does it mean when I have a vacuum that goes down to say 700 then goes up to say 800 then comes down to 690 then goes back up to 800. So forth and so on. All while still vacuuming down the system. Is there moisture in the lines?
It sounds like you have oil in your evaporator coil (common on older systems).
Could be a schrader that is not fully open also.
Thanks guys. I stopped the vacuum and ran some nitrogen though i got a better vacuum. That’s why I thought it may have been moisture. But wasn’t sure.
Looked more like product placement to me
Silly question but how Do you get the Schroeder cores back in without loosing the vacuum??
You put them back in after cutting in or adding the refrigerant. That way you are putting them in under pressure.
Slow your roll we get paid by the hour

As a residential customer, engineer, and a guy who works on his own car A/C, this comment is exactly why I'll never call you for service. I want the job done right, but I'm pissed off by slow/sloppy workmanship. Trying to make a dishonest buck off of me just makes me seek out another firm. It is depressing that unions have made it impossible for the homeowner to get certified to work on their own systems. It doesn't take a genius to do this work, and dishonest people like you drive me to do it myself. I'll end up with a bunch of great tools and probably still spend less than your service call.
Time is money bucko, if you are sitting out there wasting time on a shit single stage vacuum pump and a tiny vacuum hose from a set of gauges to evacuate a home system for 1-2 hours, you are loosing money with more service calls/installs.

@@measureQuick is it good for holding vacuum?

Why no nylog?
ALEX MIKO it is a dirt magnet and really not needed. Nylog is an assembly lube not a sealing compound. The o-rings will do the job just fine. The tackyness of nylog might cause more problems then it could help.
The only problem is you do not have a shut off to separate your vacuum gauge from the valve. Once you open up the service valve, Freon will go up into your micron gauge. And you could reintroduce moisture back into the system.
smacleod69 Well that’s a new condenser, so when you open up the valve refrigerant comes out of it. If it was service, you could purge a hose and have a core depressor on the side port and feed liquid into the liquid line after evacuation was completed.

Break vac with nitro 3 times
How much did the microns raise when you shut the vac down,that will give you a moisture content approx.
why the hell would he triple evac with nitrogen when he got down to 150 microns?
@@onetwobomb938
Because thats the correct way to evacuate a system.I guess you dont know why the system needs to be evacuated
@@davids970 why is that the correct way? Why is it necessary when he achieved a deep vacuum without it?
Not necessary, but to make sure all moisture is pulled from line set on a new condenser install.
Vacuuming the system is boiling off all moisture ,oils and to make sure you got it all out to lengthen the life of a compressor it should be broken 3× with nitrogen 1 at 2500 micron 2 at 1500 and 3 at 500
Its just good practice
@@davids970 that is completely unnecessary. the triple evac method is old and was used back when micron gauges weren't used and vacuum pumps were incapable of reaching a deep vacuum. If you pull a vacuum down below 500 microns what additional good will nitrogen do? it will lengthen the life of the compressor how?

I'm a MRI/cryo guy. We vacuum our systems down to 5 micron or less, purge, repeat.
Why not purge the system before the dirst vacuum with, say, nitrogen?(or helium)
And whats wrong with a 2-3hl vacuum pump?
I can get down to 100 micron real quick, though I have a much smaller space.
And, where was his leak test in this video? You can get a coke can to 150 mics. But does it leak?
Aorry if these are dumb questions but this process seems flawed to me. Maybe not flawed. But lazy for sure.
The system was prepurged (swept) and pressure tested with nitrogen. prior to evacuation.
There is no need to purge and repete, a triple evacuation has little to no benefit even in cryo. A single deep evacuation will do the job just as well and faster. Triple evacuation is an old school method of drying the system that was done prior to dual stage pumps. Many manufacturers still do not understand evacuation.
The decay and leak test were done at about 7:40 in the video. The software looks at the rise over the run and determines if it is a pass/fail after isolation. You can also identify a leak easily by the characteristic of the decay test. A curved line is moisture, a straight line indicates a leak.
For this application the evacuation requirement is 500 microns or less. It is a much higher temperature requirements than cryo the residual moisture is managed by the dryer. It not lazy, just not needed for the application.
Do a trip vac! Then I'll be convinced
What for? We did everything in one step.
@@measureQuick why would you not? Industry standards...
@@DanielHernandez-tp2tm You only need to break your vacuum with nitrogen if you can't achieve the "under 1000 microns for 7minutes with vacuum pump off" dry/tight test method.

What about a 40 cfm pump?
The pump as little bearing on the evacuation speed compared to the hoses. If you use 1/4" hoses on an 8-CFM pump to choke it down to about 0.7 CFM
Dax Marshall you need to watch AKhvac pull a vac with a 2cfm pump on 75 feet of lineset in like 15 min. It’s more about the hoses than the pump
Too bad that disconnect wasn't code. Wouldn't need that long ass cord.
What part of code is that violating?
@@sprockkets NEC 210.63 Equipment Requiring Servicing. There are some recent changes but there was always a receptacle required within 25 feet of outdoor units. Have a disconnect with a built in GFCI and the guy wouldn't be running his 100 foot cord.
We are not suppose to pull a vacuum too fast in case there is water in there, But isn't it too fast to go to 200 micron in 5 minutes?
In this case it might be ok if its a new install but how would we slow it down if we suspect water in system? Since we know that 8cfm on a 3 ton is actually too big of a vacuum pump.
For typical A/C applications the temperature is so high that the moisture will evaporate long before any ice could be formed. In order to form ice, you have to have standing water. There is no advantage to a slow evacuation. To manage moisture on any pump, you open the gas ballast, and that removes the moisture from the oil as it is pulled from the system. The ballast also limits the pulldown of the pump.
That is also the reason he did the isolation test at the end. If there was any moisture left in the system, frozen or not, it would not have risen so slowly.
@@measureQuick can I use the app to check decay levels with a Fieldpiece micron gauge?
@@xavierstamps7765 No, that is a patented feature of the BluVac product. MQ does not work with the FP gauge in that capacity.

Large hoses are not needed your hose will only pump as fast as your smalest pipe diameter which is the Schrader port, schrader removed will be the quickest vacuum time.

The magic is really in the hoses when it comes to fast evacuation. The FP pump just has some really cool features.
This is for experienced people - too much assumed knowledge about "nitrogen" and "evacuate" and "too fast" (I thought the whole point of this is "speed" of evacuation. How fast is "too fast" and how would you know you're doing it too fast?)
You can tell on the gauge with the decay test if you have moisture. If you do, you can slow things down or apply heat. Otherwise go as fast as possible.
This shit is hilarious
gah i want to go to this level but youre talking $1300 in just this vac setup.......already spent way too much on tools in this industry.
All you need for residential is a single hose kit and a good pump.
WTF
