To the tech doing this for 50 years,he is correct and it has nothing to do with what refrigerant you are using old or new,you and a lot of techs should never add liquid from the low side if you care about the customer’s equipment,use a charging orvice 😊
You are one of the best resources in the HVAC industry for the consumer and residential techs. Your books are like the HVAC Bible for everything residential. Thanks.....
Hi I walked into my house smelled something bad like rotten dead body is it has something to do with refrigerant antifreeze leaking 😢 @@acservicetechchannel
Thank you Mr Craig M. You and Mr Bryan Orr and your other buddy Mr Ty for truly helping me make the transition from being a Truck Driver for over 30 years to becoming a HVAC Technician. This is how one is supposed to teach. Explain 1st. Then show him how to do it Step by Step. Plz don't stop making these great videos.
Great video. I used to keep a vaporizer but I kept losing them so now I just meter it with gauges. Any time I add refrigerant, even though I’m using probes, I use gauges to add the refrigerant.
Time is money - when speed is of the essence - I use two vaporizers for years for weighing in zeotropic LIQUID refrigerants TO a system with a refrigerant recovery machine that is piston operated. This is the fastest way to get high quantities of refrigerant in a system, keep in mind that those vaporizers make a phase change and ice up, usually use two vaporizers and two hair dryers to heat the vaporizers for max speed charging without hydro locking the recovery machine, that does not pump liquid.
I didn't really wanna put this in the comment section, I also tried to find an email to message you at. Almost didn't even make this comment because its probably just a fluke case, but since you've helped me learn HVAC I figured it's the least I could do. Ordered the book bundle, it's been awesome. Just wanted to let you know the page numbers are jumbled around chapter 8 of the ac service procedure book (at least in the copy I received). Anyways, great job 6/5 gold stars.
That is very odd. Ok, please email us at info@acservicetech.com with your order number and a couple pics of that! Was this ordered on amazon or on our website?
Lol arts nd crafts, never thought id hear that sentence in this feild 😮 Wonder what Brian O would say about that ? Gotta say this is a good idea to make your own vaporizer, ive got so many extra hoses. Plus the benefit in what you said it swivels! Another thoughtful post Craig , much appreciation from us guys in the field .
Good knowledge, however I have done HVAC work for 50 yrs. and never needed such devices. Common sense is usually enough when charging systems. Maybe the new refrigerants need more care when charging systems. Thanks for the video.
Common sense ain’t so common these days. A little investment into the right setup and a tech can save several hours of work every day that turns into weeks worth of time a year.
I've been at it 15 and never had a problem also. But we need to learn and change with the industry or we will be left behind. At one point we didn't purge with nitro and didn't pull a vac, I hope you do those things regardless of whether you've been doing it 5 or 50
@@Falcon-eh8tq Always vac and changed dryers after an open system. Purged and nitro when it was necessary. R12 and 22 and oil was not so sensitive as todays refrigerants.
I bought one of these and I think it’s snake oil. I put it on my 4 valve manifold and could see liquid flow. It wouldn’t cost them much to add a sight glass.
Not sure if you have used the testo smart charging valve, but if you have then do you think it does an adequate job mixing in the liquid refrigerant to the system? I love using it, but even though I have it set to pulse charging it still charges a lot faster than I would expect and it worries me😂
Good I dea but I just meter it with the gauge manifold and use common sense and listen to the compressor go slow and have never had an issue. The schrader openings are pretty small in itself so a little common sense and you are ok.
Wondering about over charging and how it effects super heat. I added some R410 and super heat went up instead of down. I thought you were supposed to charge 410 in liquid phase? It's on the bottle.
it needs to be drawn from the cylinder as liquid, once it leaves the cylinder as liquid it can be flashed off into a gas blend and not cause issues. it constantly turns from a gas to liquid when running anyway. 410a isn't really that bad at fractionation, but still good practice to always use it as a liquid, some other blended refrigerants are very bad at fractionating. if it's as piston/other (non-txv) metering device, overcharge will raise pressure and push too much liquid through the orifice and into the coil. too much liquid won't boil off all the way or will do so near the far end of coil, thus making a warmer coil and possibly liquid flood back all the way to the compressor.
@@johnvictor2451you cannot charge a multi component blended refrigerant as a gas because the components evaporate at different temperatures and throws off your mixing ratios, yielding an unknown compound in your system.
@@johnvictor2451 straight freon? Freon is a brand name that usually refers to R22. R22 is phased out and the replacement was R410A which was marketed as Puron. R410A is now being phased out as well. R410A is one of dozens of refrigerant compounds on the market many of which are single products made by seamlessly blending several other refrigerant components. It's one liquid in a tank that separates if released in the atmosphere. R22 is a single molecule that doesn't separate.

Great work Craig like I always say you learn something new every day appreciate the work u put into your video content keep up the great work!!! 💯👍
Thank you very much for your encouragement!!
Always enjoy these and always go back and watch again. Always learning, thank you, Craig.

If you're filling through a shrader valve, it's already a tiny orifice and a "vaporizer"
Nicely done! 👍🏻

Good info. I've always kept a Kwik Charge vaporizer on my A/C manifolds for over 35 years.
Please explain why you don’t want the vaporizer as close to the bottle as possible in all cases.
I'm here 🎉
Is this still necessary if the system has an accumulator?
This is neat
What would cause. Air handler to have no power to drain safety switch.
Wouldn't waiting 10 minutes or so per 6 to 9 oz of liquid R410a still need to stabilize when added?

No link for that blue vaporizer???
I googled them. Yellow Jacket makes them. $13.69 on Amazon. “Yellow Jacket ¼” Liquid Charge Adapter”
Why not invert the tank and charge as a gas to begin with?
