Great video

I like the concept of battery powered pumps. I wish they made batter powered recovery machines so i didnt have to lig extension cords.

What about gauge options? I have a 410 unit and need to do a health check on a 22 unit. Recommendation for a decent personal set to do the job for both?

Nice work

🤘🤘🤘🤘🤘

You need to put the Hercules last

Cool video comparison!

I’ve owned the small Makita vacuum pump which was twice the cost… a couple things I like about this Hercules pump is the variety of ports, as the Makita only had 5/16. Also Makita for whatever reason stopped making 18v batteries higher than 6ah while Hercules goes up twice that. So I’d definitely give the Hercules as the best value.

Will it be good with the A2L refrigerant? That’s the only reason I haven’t gotten a battery pump.

Where did you get the vacuum hose?

Can’t believe you didn’t check those filter dryers. I bet they are getting clogged up from someone using some mo99 or 438a. Just from looking at those pressure and since someone had cut the high pressure safeties off. Those contractors looked bad too.

Very cool little pump. Hard to beat that price! I picked up a barely used JB 5CFM cordless pump. And it’s done great for me. Helps im just used to JB my company provided a 7.5CFM JB I also keep on the truck but having that cordless option is nice. Another benefit of JB is you can also have a power adapter to plug it into power if needed

what happens if the battery dies and your not close to it ? do you loose your vacuum?

Interesting product

If it gets the job done.

You can do a little bit of cutting and put a Milwaukee battery in the Hercules one

When the Navac battery operated pumps first hit the market, I was intrigued by the idea but totally put off by the price. Back in 2016 or so, I bought Harbor Freight's Pittsburgh branded 3 CFM two stage vacuum pump. I only do HVAC/R as a sideline, but it's had plenty of use in residential, automotive and light commercial. It's never let me down. I would definitely buy it again. I definitely think I'll try their cordless offering. Thanks for the review.

Both pumps are the same with only cosmetic differences

Nice review Subcool.

its most definitely a navac clone

Probably manufactured at the same plant in China. When Sears took a dump HF became hard to beat regarding ratchets & wrenches with their return policy being very easy. I’ll definitely get that pump when my YJ Bullet fails. I’ll be damned to pay $900 for an A2L/A3 compliant pump.

A Hercules 20v 1/4" quick release impact was my first tool purchased when i got the industry 7 years ago and its still going strong. Lol

Great review!

For the price point it did pretty good. NAVAC makes vacuum pumps for a lot of manufacturers. I'm definitely a NAVAC fan....but $260.....hard to beat that performance for just about half the cost

I got the O-Ring Assortment, 382 Piece set, for 10 bucks, saved my ass on the cheap a few times. I love me some Harbor Freight.

Leaky business

Good to know you could check those caps without pulling them out

Been so busy the last few days. OT hours are starting to match my regular hours. Its that time of the year again.....grind level....cranked to the max

This dude really check a wet spot with his fancy sniffer? Gotta be a union guy on the clock. Bruh just fix it, we all know it's the easiest part to fix and most expensive.

With that much water, that leaks been there a while and someone knows about it. Those joints should be pretty sealed, otherwise there'd be a flood under that chiller.

I have four old Trane ahu in a building at work. They are work horses. Think how many have came and went and they keep going

Great video. Thank you for sharing. May I ask, which's voltages water cool chiller use ? Could we have part 2 water cool chiller repair leak ?

Funny you take care of an air handler from 1965. I work for a school district and at one of the high schools I take care of an dx air handler original to the school from 1965. Initially it used R-12, and 20 years later was converted to 22.

Gotta love/hate pneumatic controls. Hey what is that flashlight that you use? I have been trying the nebo lights out and they die in like an hour.

She is a leaker

Wow awesome

Curious why they don't connect the return air directly to the air handler?

Lower the water level..seems like a lot.

I have worked on a few of the york millenium chillers and i just dont care for them. They are not as good as trane is.

Great video. Thank you for sharing. Those are big chiller

Loss of subcooler seal is when your drop leg temp gets lower than your condenser temp. It basically is calculating that there is flash gas instead of a full liquid seal. Also on your drive heat exchanger, pull both heads when brushing it. One side may look ok, but when you pull the other, it will look like shit. It’s more work, but in the end its better.

Thought you were in a factory or so.ething at first lol.

Cool video. Glad to see they raised the liquid level....60% seems a tad high, but i get it. During start up, it seems like they always set it to 35%-37%. We do the maintenance and repairs on our customers YK's. Did they clean the heat exchanger for the VSD coolant. That can get pretty nasty over time. A lot of people wait till they get high temp alarms before doing it though. Enjoyed the video...thanks for sharing

Sounded like the Titanic engine room at the start!

Sounds like that there is the EMERGENCY STOP BUTTON FOR to immediately stop a machine.

That sound at the start had wondering what the issue i was saying must be surging lol

That’s a looooooooooooooooooooong sensor

😅 South FL 🦎

Cool machine

found your channel i love it. at a risk of sounding dumb is this a small part to a massive air conditioning system my local hospital has a massive set of evapco towers on a two story standalone building always wondered what it was for
