@@diegolopez19 I really hope you “lmfao” because if not this comment is less than worthless. Trade school is a joke and anyone with a brain knows that. Nice try though.
Outstanding demo!! Finally, someone has explained the fundamental questions I had on "how" refrigerant flows through an AC manifold with respect to the High & Low control knobs. Well done and thank you!!
Good video. I bought my own gauge set for car work. Things that confused me at first is the valves on high and low do not change pressure reading, that took me awhile to figure out, so good pointing that out. I've been trying to figure out what the smaller temp numbers are used for on the inside. Tip for folks doing r134a like me. Make sure Schrader depressers are fully counter clock wise prior to quick connect. Then turn them in slowly till you read pressure on gauge. That way you do not hurt that Schrader on low and high lines from over compressing them.
As a recent graduate of trade school and new in the field these videos are awesome. I typically try to get in 2 a day. If not at least 1. Appreciate it Brian and Kalos.
2:15 I really appreciate you calling yourself out about that. Ever since I got into trade work a couple years ago, people do this ALL THE TIME expecting me to know what they're talking about and it is beyond annoying. It's the little things...💯
Absolutely outstanding overview and review! Just what I was looking for. Been years since I used, and wanted to refresh memory and this was perfect. Timeless video.

Question. Sometimes when filling with r134a, or r410a, the sight glass will be liquid at first as im filling. However after a few times of adding a little, the liquid can no longer be seen in the sight glass flowing. Gas is still flowing from the cannister, but it is no longer liquid. The cannister is not empty. Why is this? Less cannister pressure causing the liquid to vaporize in the tank maybe?
I would love to see a video showing the replacement of a gauge on the manifold with another guage. What tool do you use? Is it easy or hard? Is it safe? Are many of the gauges compatible amongst different manifold manufacturers?
simple, use any basic tools (wrench or crescent), add either a thread tape or thread sealer. . unscrew old gauge, add sealant to new gauge threads. twist on.
How do you feel about the ones that dont have a sight glass but instead have a little schrader valve on the yellow center fitting for burping air out of the line?
Would you disagree with the idea that most licensed HVAC contractors are reluctant to work on the installation of the low cost mini-split units sold by the "big box DIY stores. Seems like HVAC contractors service and install only the specific big name HVAC manufacturers they prefer.
Is it bad to open both the high and low side valves up at the same time while the system is running? I realized I had both open at one point and it seemed like it made made my pressures shoot up pretty high but idk if it hurt anything. It seemed like it made my pressures read inaccurately too
My yellow hose for the MGS has a sort of valve inside one of the hose ends. The instructions do not mention which way this valve is supposed to face ( gauge set or refrigerant/ vacuum pump side) Any ideas?
You say not to do this as a home owner but I can't afford to pay 300 every 2 months with a leaking condenser so propane refrigerant it is wooo I've already got a guage set from automotive just gonna make an adapter to home ac fitting and Charge my gas pack full just to get me through the summer till I can afford a new unit come next spring Just bought this house
You should purge or evacuate the hoses/gauge to avoid cross contamination with other refrigerants since thats bad for the system. I’m an HVAC student if that helps.
In fact, I did my read, with out cert. you can do your own home with 410 and its completely legal... you can NOT do R-22 at all. However you can NOT do a friends home with 410.
now consider that, as a taxpayer, you paid some public servant to come up with that "for yourself, but not your friend" law. torches & pitchforks, anyone?
@@JScottTalbert-Lawyer2Warrior Usually the codes are developed by caring people who are trying to help everyone get along in society. Sometimes bad companies or trade associations force laws into the code books that only benefit themselves and shut out others. The International residential code went a long way to eliminating the regional “good old boy” codes but there are still manufacturers and material sellers forcing excessive regulation and costs on the public.
I was trying to say to add refrigerant you would open low pressure side valve on the manifold but i opened the high pressure side instead for 30 minutes and it did not add any refrigerant. Now my concern is did i damage my ac system?
thank you very much so understanding as Legale home oner or personal use I can't do (Care or my AC ) system until I have the certificate you mention (EPA)? if yes so from wear? and how much it will cost and how much it will tack time ?
Do you always recover refrigerant through the high pressure side??? So you're saying you put in refrigerant on the low side and recover on the high side, is this so for all refrigerants should they be put in on the low side as a vapor, and recover on the high side as a liquid. What about 410-A does it go in as a vapor or does it install as a liquid on the high side???
I just started my first Hvac job I told them I had 5year experience got the job getting paid really well but I actually don’t have 5year experience know very little. Hopefully they don’t find out.
In my country most aircon technicians come from india. Yhey dont appear to have any certification at all yet they charge exorbitant prices. I am planning to do this on my own.
hate that lame disclaimer do not use it unless you're a trained professional. I get you're trying to protect folks but it also sounds like you're looking to protect jobs for the industry. IMO, if you're diligent with safety and did your homework, you're good to give it a try. Definitely safe if you've been taught by someone too. That's how I learned plumbing and electrical and people always say the same thing. All that said, obviously try at your own risk so do more hw and be extra careful if you want to lower your risk. I'd rather be told that then to not try at all unless I'm a trained professional. =)
... especially when you have comments stating they learned more in the video than in trade school. such a crock... and a money racket. any retard with a bit of patience & tenacity can eventually figure out what to click, turn, pull, etc.
Small difference: the EPA wouldn't fine someone $37,500 for a plumbing or electrical mistake. Handling refrigerant requires passing a federal epa test. Your comments sounds to me like saying thay everyone should be able to try driving a semi because you were able to learn to drive a forklift and tractor because your friend owns them. You might be right that it's learnable, but it isn't generally legal to mess with refrigerant. Which is probably why they have the disclaimer. Let the very helpful channel legally cover its butt. Just ignore it. Yes I know that I'm replying nearly a year later. I'm bored and wanted to reply.
I'm an apartment maintenance technician with about 4 years of experience, occasionally working on HVAC. I've been studying this stuff 3 hours a night for the last month and work on the systems pretty much daily at this point. I don't have my EPA yet, so I don't handle refrigerants and I don't touch gauges. Neither should you if you don't have your EPA.
i hv a question,i was trying to charge my honda civic ac and did attach r134a but i was notgoing through the low side but i open high side it went through ,could any one tell me why this thing happened .thx
Nanny state patronising home/car owners what they can do with their property, so others can print money and govt. earns by issueing certificates? Not with me...! Trouble with this scale is, I'd need to convert this into bar and censius.
Why did you posted this video for everybody even for kids when it supposed to be for trained professionals? Do you think with all these information a homeowner will not use it? --- What EPA certification? I went to School for that and is the most stupid and ridicule process that don't even count. Do you think a person will learn anything in 3 months school intensive course? I get out with EPA certification and I'm sure I didn't know a shit. This is all to take our money. I lost $ 4.000.00 in that school, and I have learned 10 times more in TH-cam

It’s an art to know how to keep explaining something. Not bad.

Should have shown zeroing the low side, vacuum discussion and values on the low gauge. The infamous 500 microns...

Should you avoid using the same manifold and hoses set on r22 and r134a systems? Or there is a cleaning procedure? Thanks
You should purge or evacuate the hoses/gauge to avoid cross contamination with other refrigerants since thats bad for the system. I’m an HVAC student if that helps.
Good class I think there’s refrigerant in those veins.
Cool video
Do you know where I can buy the "parks" fittings? I've been searching everywhere online and can't seem to find any.
no. of videos i seen all invain about manifold guage . here i got answer.
professional video.like it
Thanks for the video =)
What happens if you vacuum refrigerant with car running I messed up and did this now refrigerant not sucking at all

This all depends on if it's fixed metering device or txv, and what refrigerant.
Still trying to save some money to buy the vacuum pump. Any alternatives to share ?
Suck on the hose really hard! Or just go to an auto parts store and borrow one, they're free at some stores.
@@sylviaisgod6947 Lol. Thanks.
Excellent
BRAVO!

Does at least the basics of this type of manifold apply to an automotive a/c system?
Look up ( scotty Kilmore ac gauge) he shows u how to do it

Do you need a 608 license if you just wanna buy 134a to get high?
You need a small bottle of amal nitrate to whiff if you want to get high. Do it right.
