I get asked often why I choose a one hose vacuum setup over a traditional two hose setup. It’s easy, fewer connections (leak points) is always better for a speedy vacuum process. And when you use a 3/4″ inner diameter hose with the 8 cfm Fieldpiece VP87, paired with the MG44 vacuum gauge, you can verify a quick and accurate vacuum. This setup has worked great for all the different applications I’ve worked in. Unless I’m working on a very large HVAC system, it’s a one hose setup for me. Hope you enjoy the video!!

One thing that's pretty neat about those fieldpiece manifolds, when you put the suction clamp on the refrigerant line during test tightness, it will factor in the change in ambient temperature. So that -.6 that you had might have just been ambient temperature decrease.

Can’t wait to try this set up thank you !

Adrian Podufaly says:

Are you looking to hire a helper? lol

Tanner O'Donnell says:

Trane and American standard recommend pressure testing to 250 psi, anymore will push through the service valves so I’ve been told. I do the same thing with vacuum though tru blu on the suction line and my BluVac micron gauge on the liquid

Terms of Service says:

What boots are you wearing by chance? Or are there particular brands you would recommend for someone getting into the field?

Luke Bunyett says:

Why did you take the shredders out?

Chris Gonzalez says:

You always giving us the game much love bro

I do more refrigernation than AC and maybe that is why i do this but I find the smaller the system the more important it is to keep the vac gauge away from the pump, also on really small stuff I find my appion hoses pull too fast and I get mositure freezing in the system if I am not careful. On larger systems it is gonna take awhile to pull a good vacuum regardless, I was on a walk in cooler for a high school that was started up like 6 months ago (not by my company) that has a 3ft tall reciever (the system takes more than a full can of 448a), I had to flush and vacuum the whole system the other day. I didn't want to start shit so I kept my mouth shut to the customer but the install team screwed the pooch on that system. I was there because the evaporator was dripping on the floor, heavy frosting on the entry side of the evap, big shocker low charge, the valve core was so loose it was dripping liquid, I charged it to a clear sight glass the compressor cycled off and that when I saw it, sand cloth dust floating in the sight glass lots of it. I talked to the MFG because it was still under warrenty and suggested that we needed to flush the system or this compressor won't make it even to the end of the warrenty, they agreed and I spent the next few hours on a cold windy roof, lol good times, also thats the first time I have seen so much dust in a system that it was immidantly apparent in the sight glass. Great videos too man keep up the good work.

Soy un admirador de su trabajo. Yo también me dedico a lo mismo y algún día me gustaría ser tan bueno como usted y tener toda esa herramienta que te facilita mucho el trabajo. Para hacer trabajos perfectos.
Quisiera saber si puede subir video con un equipo minisplit haciéndole la prueba con nitrógeno, me gustaría ver ese procedimiento y aprender. Muchas gracias por subir y compartir sus videos.
De antemano muchas gracias y espero y le llegue el mensaje y me de una respuesta. Cuidese atentamente un servidor y admirador.

1 hose is all you need in residential the systems don't have that much piping. You can tell right away when you put the micron gauge far away a tight system is doesn't typically move at all. Not a huge fan of the fieldpiece vacuum it has nice features just way too bulky for me.

Raymond Svoboda says:

I hear what you’re saying with the 1 hose set up being furthest away from the pump. I’d still rather use 2 hoses with two core pullers. Have the micron gauge on the side port on the core puller of the liquid line. When you need check microns, valve off the core puller on the liquid line so you are not longer pulling on the micron gauge directly and you will still have an accurate reading. But I guess when you are pulling on such tiny systems it’s not like you’re saving that much time anyway with the two hose setup. To each his own I guess.

AJairo Almaraz says:

Milwaukee Packout tote. New load out?

SirFishAlot says:

I like a core removal tool on the the micron gauge to reduce oil getting in it when you release the charge.

John F. says:

Nice setup and install. Here in my area in Texas that would fail inspection for being too close to the gas meter and for disconnect behind the unit.

Take a ride with me says:

All Trane/American standard units say to pressure test to 150psi. We had 6-12 units where the nitrogen wound up contaminating the refrigerant due to it pushing through the service valves during a pressure test. We thought there were leaks due to the pressure dropping, only to find out it was leaking into the outdoor. At the high cost of 410a that can be an expensive mistake.

Not even gonna lie I only start watching your videos a couple months ago not understanding shii til I got to school FW today I’m actually able yo follow along and understand and appreciate your vids because it’s entertaining and helps me at school

Banaa Man says:

Good day boss from Ghana 🇬🇭 please is it necessary for HVAC TECHNICIAN to learn HVAC systems design… Wait for your feedback

Chris 74 says:

Sometimes there just isn’t enough room to use the core remover tool. So I just hook my hoses up to both sides.
