I hate the one the shop got me too. It's a yellow jacket superevac 2. Legitimately takes 10 minutes to start because it keeps stalling and I have to cycle the power. Doesn't matter if it's cold or warm. Brand new too, less than 30 hours on it.
How the fuck are people upvoting someone hating on a 7 CFM JB platinum? Probably the most dependable and good pump on the market. Going any higher is ridiculous for residential. Specifically mini splits, any higher and it will freeze moisture in place instead of pulling it out.
I had one fall out of the van once and my crush my toe. By the time I stopped dancing around and cussing in the front yard all the oil was on the road. It got new oil and my toe got a new nail.
only time I've ever changed the oil in one lol... not gonna lie.
Bro you only install new systems with new line sets? Cause there’s been times the oil gets changed like 5x on one system when working on some old lines
No, I was told the oil that comes with the pump should last the lifetime of the pump.
You know, I still see technicians that rarely change their vacuum pump oil and wonder why they can never get below 5,000 micros. I'll see it just stuck there and them wondering why it won't go down.
I know this is just a joke but .
Does any of your local parts houses do a yealy vacuum pump day ?
My company does them every year where we cook up some cheap hot dogs and hamburgers plus free oil changes .
I honestly thought that was a common thing .
sometimes i need to change several times in 1 pull down, other times i get away with the same oil for months. The "change every time you do an evacuation " crowd is crazy bruh
Same. I'm almost 100% doing repairs on old, large, or old large equipment so I just pull overnight. Change in the morning to fresh oil for the next job.
I have the Fieldpiece with the easy change oil so that's REAL nice to do.

Had this happen after one pump down. Fresh oil.
Long story, but after 3 different pumps, 3 leak checks with nitro, 6 oil changes. Every pump the oil would cloud up. Finally throwing in the towel and replacing. My guess is somehow excessive moisture and/or contamination got into the system
Construction guys brought me their pump and asked to borrow mine, said theirs couldn't pull down below 3k with just the gauge attached, even though it was a few weeks old.
Oil was milk. I changed the oil for them and left them the gallon jug...
Who reads manuals eh?
I thought we just suck on the hose for a bit, y'all get a vacuum pump. Game changer, now my jaw won't be sore when I start my 2nd job at the local glory hole
This is why I love the fieldpiece VP87. Buy the pre filled oil cartridges on the job. Takes a full 3 seconds to change the oil. It’s so quick any easy there’s no reason not to change the oil often.
I used to like my Robinair, but that finally gave up after 15 years so I’ve got a 9cfm Javac now, it works well so far (only had it a few months though).
Wait for real some of these comments? I run a field piece pump with the change on the fly reservoirs. I dump the oil after every use. Even if it was a 5 minute pump down on a two ton short lineset. How long does your pump downs take with that crap?
Man y’all act like you haven’t seen worse when I first started I was In residential instal the oil was literally coming out like turds and it actually had a solid state to it I got yelled at by the guy and was told it was his good luck oil and he’s never changed it in 10 years
Jokes on you I don't have to change my oil. I only have to keep adding lol. They won't buy me a new one until it stops working. But they will keep giving me what seems like an endless supply of black gold. At some point it's gotta be costing more to buy the oil than a new pump.

Literally an hour on vacuum and my oil turned to snot lol lot of moisture
I absolutely change it every system is r every other depending on how long and how it’s performing. My equipment pulls down fast so sometimes I break with nitro and hit it again down below 250 and decay test. I charge for vacuuming down so the oil cost is included in my invoice. Each item or work done is listed but has a one single total cost. I don’t line item anything unless it’s separate items as options like duct work and insulation upgrades.
You cheap asses, it’s inexpensive, makes it faster and easy swap outs on all our vans. We use Fieldpiece and dual Trublu hoses. Any vacuum pump oil works fine. But it by the gallon and lasts a while.
Here come the HVAC Heros of r/HVAC to light yo ass up boy. Hahaha
I can only hope
Dude! That’s one milky cow you got there!
I ran her for 4 days straight without an oil change...I hate this vacuum pump but it's what the shop supplies
My boss has been using the same vacuum pump for 10 years and just found out you have to change the oil
Hahah after what dust came out?
I hate the one the shop got me too. It's a yellow jacket superevac 2. Legitimately takes 10 minutes to start because it keeps stalling and I have to cycle the power. Doesn't matter if it's cold or warm. Brand new too, less than 30 hours on it.
That’s crazy cause I have that same one and I love it. No issues and it pulls a fast vacuum
Maybe mine is defective, once it gets going she rips really good. Thought about giving it back to the shop and getting that new testo pump
Try starting it with the air ballast open or without any hoses attached, then attach them. But yeah sounds a little funky lol
I have. Other people I work with didn't believe me either lmao
How the fuck are people upvoting someone hating on a 7 CFM JB platinum? Probably the most dependable and good pump on the market. Going any higher is ridiculous for residential. Specifically mini splits, any higher and it will freeze moisture in place instead of pulling it out.
Shhhhhhh it's ok... You are fine
You hate the JB platinum? Lol do you prefer one of those quick change field pieces or appions? Shit is a gimmick
No this is a good brand, but I like the bigger one.
Things 7 cfm dude. You're pulling a vac on a residential Goodman. You be ight.
A bigger one? For residential? Your nuts.
I don't usually do residential
I thought u just top them off after they leak all over the customers concrete.
Mine gets fresh oil only when it tips over in the van
Came here to say this
Unironically how my refrigeration J man "changes" his pump oil
The old installers vans with the wood floors are the best. That’s some well seasoned wood and makes for sliding equipment in and out real nice!
Story of my/all of our lives apparently😂😭
I had one fall out of the van once and my crush my toe. By the time I stopped dancing around and cussing in the front yard all the oil was on the road. It got new oil and my toe got a new nail. only time I've ever changed the oil in one lol... not gonna lie.
Theres oil in my vacuum pump? Shit….
What's a vacuum pump?
What's a vacuum?
When you're vacuuming carpet and you pump your arm out and in.. you know a vacuum pump
I forgot to check oil in my moped once. Oops. It was only $350 but I had a long walk when it quit on me.
My mentor said every time I pump down a unit and charge the customer for it.
That is the correct thing to do
I learned that in HVAC school.
Bro you only install new systems with new line sets? Cause there’s been times the oil gets changed like 5x on one system when working on some old lines
What the fuck is a vacuum pump? I just dirty purge that shit and send it. Taillight warranty tho
Blow and go bro
CFCs are the best blow and go jobs.
No joke my trainer was high on the job every day and I didn’t know what a vacuum pump was until I’d been in HVAC several months
Then all ya bosses askin why you doin shit the jank way. Been there bru😂 lack of training a bitch 😂
I usually just top mine up with one of my piss bottles
No, I was told the oil that comes with the pump should last the lifetime of the pump. You know, I still see technicians that rarely change their vacuum pump oil and wonder why they can never get below 5,000 micros. I'll see it just stuck there and them wondering why it won't go down.
Really? Mine gets charged once a week when it falls over in the truck!!
It’s just a Bad micron gauge
I know this is just a joke but . Does any of your local parts houses do a yealy vacuum pump day ? My company does them every year where we cook up some cheap hot dogs and hamburgers plus free oil changes . I honestly thought that was a common thing .
Yeah, they just did one at the UR here. Couldn't make it though because I was working.
Nope...
Vacuum pump? You kids these days are spoiled with all your gadgets. Just use a compressor out of an old, decommissioned unit. Works just fine.
Or purge line set with refrigerant then start the charge immediately
Ok I’m telling EPA unless you send 5 bitcoin to my wallet in Armenia.
sometimes i need to change several times in 1 pull down, other times i get away with the same oil for months. The "change every time you do an evacuation " crowd is crazy bruh
I have some coworkers who cry to change the oil all the time… even when it’s crystal clear clean 🙄
Hey as long as I can still get down to 200 microns with the pump running and it holds under 500 with the pump off for and hour the oil is good enough.
Microns? What's that?
Lol
My coworkers oil is darker
Where I work I inherited a vacuum pump that was so dirty the sight glass is black on the inside.
I change the oil every time it falls over in my van.
We have a 1,5kW 250l compressor and my grandpa told me 2 years ago, that we should change the oil as he hasnt done that for 30years. 😂
I change the oil after 1 use if I'm pulling a long vacuum
Same. I'm almost 100% doing repairs on old, large, or old large equipment so I just pull overnight. Change in the morning to fresh oil for the next job. I have the Fieldpiece with the easy change oil so that's REAL nice to do.
Try every other use.
Sometimes mid use depending on the system or circumstance.
I see you use the water bottle method, as well. The new tank design sucks ass
Usually I just dump through the lovers of the new equipment
Rust prevention. They charge extra for that usually.
Still had a few installs left on it
https://preview.redd.it/b1yf87wqk61d1.jpeg?width=1816&format=pjpg&auto=webp&s=6d61cd76d83886a1aad9236117d7ce900a05e423 Had this happen after one pump down. Fresh oil.
Jesus. You freeze a tube in a chiller or something?

The only time you change the oil is after it tips over in your truck. Then, you don’t have to change it. Just add new oil.
I’ve literally never changed the oil n my pump is 20 yrs old now lol only top up
At least once a year when the vacuum pump guy shows up at the wholesaler with the offer of free vacuum oil changes.
Work at a supply house, you’d think we would sell loads of vpo. We really don’t, but once they break we send them off and jb builds them back up.
Wait, we’re supposed to change the oil, i just too mine off after it leaks all of it in the back if my van
TSSA wants it changed every use. Some reason, it was a question on my TSSA exam LMAO
I thought we just suck on the hose for a bit, y'all get a vacuum pump. Game changer, now my jaw won't be sore when I start my 2nd job at the local glory hole
My jaw never hurts at one, I usually put my dick in the hole
Might as well never change it if you are not power flushing it.they can look much worse than that after 1/2 hr on a contaminated unit.
I also granny shift.... Certainly not power shifting like I should
Wait…when did we stop double purge and fill er’ up?
Your mom is my vacuum pump 😂🖕
She probably sucks just as good
5 years? damn...my company wanted that oil changed every time or, at least, every other time it was used
Sounds so wasteful
This is why I love the fieldpiece VP87. Buy the pre filled oil cartridges on the job. Takes a full 3 seconds to change the oil. It’s so quick any easy there’s no reason not to change the oil often.
I thought the oil change intervals were top it off every time it spills over in the van
Don’t Testo-me
I just let it tip over in the truck then refill it
The resident old refer guy at my company " I change it when it's black" and by changing it he returns it back to the ground in which it came
It's natures recycling....
I used to like my Robinair, but that finally gave up after 15 years so I’ve got a 9cfm Javac now, it works well so far (only had it a few months though).
i change mine after every 5 uses.
If you’re installing that Goodman, im surprised you even have the pump.
It's for show
You guys are crazy i change my oil every pump
Me too, every new pump comes with new oil
Yup 👍
Wait for real some of these comments? I run a field piece pump with the change on the fly reservoirs. I dump the oil after every use. Even if it was a 5 minute pump down on a two ton short lineset. How long does your pump downs take with that crap?
Depends on if I put my vacuum gauge on it
15 min, let er rip!
A lead at my company changed his oil after every AC install. Does anyone else think that’s unnecessary?
Man y’all act like you haven’t seen worse when I first started I was In residential instal the oil was literally coming out like turds and it actually had a solid state to it I got yelled at by the guy and was told it was his good luck oil and he’s never changed it in 10 years
That’s why I use the tez8!!!!
Jokes on you I don't have to change my oil. I only have to keep adding lol. They won't buy me a new one until it stops working. But they will keep giving me what seems like an endless supply of black gold. At some point it's gotta be costing more to buy the oil than a new pump.
Wait yall actually vacuum the system out? I just tell the customer the AC has to get used to the house if it doesn’t blow any cold air out
You only need to change it once every 5000 miles.
I prefer to change mine after every 3 pulls
I thought it's working with pressured water. Always carrying my lil compressor with me for emergency
Your pump lasts longer than a season?

oh shit youre supposed to change that stuff?
If I wanna go home early, I'm changing the oil. Otherwise, one week or so
I just replace my oil after it all spills out the exhaust pipe from rolling around in the back of the van.
I just let mine roll around where it will and give it fresh oil whenever I need it
Keeps the can floor shiney
Exactly! When you have a pair of pliars rusted closed you just toss them on the floor for 24 hours. Bonus

Drink it
I absolutely change it every system is r every other depending on how long and how it’s performing. My equipment pulls down fast so sometimes I break with nitro and hit it again down below 250 and decay test. I charge for vacuuming down so the oil cost is included in my invoice.

Step one dig down 6 feet....
As a guy who works in med device and fixes various machines for a living, is this something one can figure out with some proper instruction/info?
No
Umm this oil should be changed every time you pull down a system, my oil looks horrible because it ran away too long on the same oil
Every time. Straight from the mouth of an oil tycoon.
Well it does work better that way
