Great video just want to add a little tip as how i remove hoses under pressure. I have been at this trade for 25 years, when disconnecting high or low side apply pressure to the hose while loosening then once the hose is loose you will loose hardly any freon if any, its a matter of keeping pressure as if the hose is still seated, takes a little practice but youll know what im saying when you do it. I got tired of getting blasted by the spray till i though about what i was doing wrong, hope this practice helps. do whats best for you but this is what i do.

[@qn9792]

Thanks for the tip. I will keep this in mind.

[@duganfr]

As in putting pressure on the sealing surface? Pushing the hose against the port as your loosening?

This can kind of backfire on you until you get the hang of it, so do t panic, it takes a few tries to get it right, but it’s a great way to remove hoses. 😎

[@patrickwolfe2753]

Rule # 1 turn off unit before taking off high side service line. Please take off low side before turning off unit.This will also contribute to low emmisions. Also please confirm your operating pressures and refer to saturation tables for correct refrigerant charge.Basics buddy,but congratulations on your presentation, good on you. This is Desert Fox.

OK, so A lot of comments here are attacking this young man for doing what others are not. He made this video to give pointers to homeowners so that they are aware and educated enough to know what the techs are doing. I personally have been ripped off on a tech that overcharged for capacitors and refills on refrigerant on a 6-year-old unit. I was renting out the home to close friends and I was out of state when I got a call in July that the AC was not cooling so I went to yelp and made a choice to go with the higher rated Ac service co. Well, 3 months later I had the same problem with the same unit I called a different guy who checked both Ac units for leaks and cleaned out the coils and replaces a Schrader valve and topped off the refrigerant. I believe in transparency so this Guy is helping many to understand where to start and of course, every adult is going to do further research so don't knock this guy for helping many. The other constructive criticism helps people out and this guy is honest enough to say thanks to those comments so guys keep up the helpful comments to educate each other out and don't hate because he's helping homeowners. Keep this educational.

[@AZ_sunshine]

SN, thanks for voicing exactly the way I was thinking. Not fair that the critics think it is ok to speak for all of us. I so appreciate guys like 'Word of Advice' giving up their time to share. I find videos like this very helpful. I have an AC unit acting up and watching this video leaves me less vulnerable when the technician arrives. Thanks again for sharing what I am sure a lot of people were thinking, but did not write it.

[@sethfunkhouser7909]

I am totally in favor of people learning about my job. Helps me explain what I’m doing easier when the customer can understand some of the lingo. Anyway I agree with your comment and thought it would be worth noting That your refrigerant should not require being topped off as a Hvac system is hermetically sealed. The system does not “use up” refrigerant. If you’re low you have a leak and that needs to be addressed. Thought you would like to know :)

[@aarongray503]

@@WordofAdviceTV I am registering for classes for the fall semester Jay. Do you have any advice for students? Like did you only take residential or commercial aswell?

[@WordofAdviceTV]

@@aarongray503 Hey Aaron! When you said you got interested in HVAC, I didn't think you meant that you were interested enough to actually start going to school for it! :) Nice! I took one year of residential and one year of commercial because I wanted an associates degree in HVAC, not just a certificate. Since I am not planning on going into commercial, I really didn't need to go that extra year.. But who knows, maybe someday that will come in useful. I wanted to join a union and keep going to school for another 4 years after college when I just started on my journey. But plans changed and I stayed with residential instead. As for advice for students.. Here's a couple things off the top of my head: 1. If you do not understand something, do not be afraid to ask a question. Even if it makes you look dumb lol. There's a good chance that others don't get it either but they don't want to look un-smart in front of the class/teacher so they keep quiet. In my class I was known for being the question asker, other students eventually started to rely on me to ask most of the questions. (some would suggest questions that I should ask) So make sure you understand what is being taught, keep asking questions if you need to. 2. Take notes in all your classes even if you don't have to. I still have a huge filer folder where I have notes and hand outs from all of my classes. I took detailed notes and drew the pictures off the board. Writing things down helps you remember the stuff better and can be a resource for you later if you need it. 3. If they have a lab where you can practice hands-on, like soldering, brazing, wiring, troubleshooting, etc, make an effort to put more time into that. If you finish before others, well then solder a 3d square or something while you wait for the others. The more you practice the better of course.

[@aarongray503]

@@WordofAdviceTV Well originally I never intended to be this attracted to hvac. Just wanted to learn to save money from having someone come to my house and fix something that I could learn to do myself. The tech that came to my house has his own business and told me I seemed like a smart young man because I told him everything I tried to do to troubleshoot/fix the a coil from freezing up. He offered me a position if I were to get my associates degree in hvac. So from a big push from him and my wife I am now pursing this trade. It's going to be tough because I have a three year old and a baby on the way but I want to better provide for my family and have a trade that will last me years to come and hopefully enjoy it at that! Thanks for the advice I will for sure follow your words of wisdom. :)

[@WordofAdviceTV]

@@aarongray503 Sounds exciting! It will be tough but I'm sure you'll do well! Especially since it sounds like your wife is fully supporting this venture. I have an associates degree in accounting. I felt so useless doing that lol (it was really boring too), a man who can't really fix anything around the house. It's much more rewarding doing this trade instead. I know a guy who only has one arm and he decided to go to school for HVAC as well. If things get tough, remember that at least you got two arms.. Four more points I would like to add to my first three though :) 4. If at all possible, it would be very beneficial for you to get an HVAC job as soon as possible while you are going to school. There are many places that will hire new guys that just started going to school. I know this may not be possible since you already have a family going but it would help you a lot in school. Stuff that you run into at work you can then bring to class and talk about it with the rest of the students and teacher. Since you have watched so many KZbin videos on this topic already, you will have a giant head start on most of the other students by the way. 5. Do not be afraid to switch jobs. HVAC technicians are in high demand. Once you get some experience, look for better opportunities until you find one that works best for you, fits your schedule, gives you more time with the kids, etc. When I went to school, by the time the second year was ending, most of the students were on their 2nd or 3rd job. Employers would come to the school to try and recruit people. When I switched from my first job to the second one, my hourly wage went up by $10. So just don't forget that your family comes first. Even if your employer will be very cross with you for leaving.. If it is better for you and family, do it. 6. Don't burn bridges. If you are switching jobs, try to quit as respectfully as possible. Thank them for everything they have taught you and for giving you the opportunity to work there, etc. You never know if some day you may need to come back there. 7. Be cautious of the 2-week notice. When I put in a two week notice at one place, they released me that same day and had someone drive me home (I had a company vehicle). So be aware of the possibility that you may be let go immediately instead of in two weeks. Comes as a bit of a surprise when you didn't see it coming. Might be a little hit to the wallet. This is a good topic! Didn't think that I would end up typing all of that out.. Maybe I should make a video for new HVAC guys where I talk about all this.

[@surferdudedon9249]

@@WordofAdviceTV You should replace the hose immediately when it has discharged liquid refrigerant and is cold enough to dew point inside the fitting. Time is of the essence since you can wait too long and the refrigerant vapor produced by the residual liquid evaporating will dissipate and the moist environmental air will dew point on the cooled inside of the fitting. Liquid water will be introduced into the system when you shoot the hose contents it into the suction port.

Good vid. I would add - 1) Only use one gauge for each freon so you don't cross contaminate the different oils and freon. 2) All medium temp operating saturated suc temp should be around 35-45 degrees. 3) In the off cycle freon will migrate to the coldest location in the system. 4) Checking the difference between the saturated suc temp and the suc line temp = superheat. Most system = 12-20 degrees. 5) The difference between the saturated liquid temp and the liquid line temp = subcooling. Most system = 10-15 degrees. Have a great day!

[@yougoog1]

Great info! What do you suggest about how to measure the line temperatures? What kind of tape should I use to tape the thermocouple lead on to the line pipe? Also, how to check if thermal expansion valve is used in the ac system as it regulates the superheat if it is used. In this case, the measured superheat may not help tell whether the Freon level is low or not.

[@darrylsjodin3962]

Your video was well done and it was good you express concern about introducing air and moisture into the system because that is the biggest risk when gauging up to a system and over time, when done incorrectly, can cause operational problems. It appeared that your gauge set was flat when you attached the suction hose and I was waiting for you to instruct us the purge the gauge set through the middle yellow hose and the high side red hose with the system freon to remove the air from the hoses but you didn't. 😕 The air in the hose doesn't necessarily remain in the hose when connected to the system, especially when you start the compressor and the low side pressure drops from 100 psi to 70. It is good to run the liquid from the high side hose through the gauge back into the system but only if the gauge hoses were purged first. Blowing gas from the high side hose into the atmosphere didn't necessarily puve the hose, but only released some of the freon. So, sorry to say but it looks like you blew some of the air that was in your middle hose and all of the air that was in your low side hose, directly into your system when the opened the gauge and ran the liquid from your high side hose into the low side. What I've been doing for 37 years is gauge up the low side hose with the left knob on the gauge set open slightly and the center hose loose and the high side hose attached to the system but not threaded on enough to push in the stem, and guess how long to let the vapor purge through, a few seconds, and tighten up the other fittings, preventing air from entering the system. FYI also, when you remove the high dise hose and the liquid freon blows out, it freezes the Schrader fitting, causing frost and moisture to form inside the valve, around the stem. If you don't put the cap back on quick enough you can trap moisture inside the opening of the valve and push it into the system next time you gauge up. If the stem leaks like you mentioned, put the tip of the screw driver in at an angle under the lip of the stem and pry up slightly to seat the valve better. 🙂

Thank you very much. Around 2:50 into the video you mention that one side is a dummy connector. I have this same set as you're showing at that time since last September 2018 and no where have I read or watched that one side is closed. Thank you very much.

Thank you watching from Philippines

[@charosenz]

excellent video. Thanks for not adding annoying music too....

[@n2n8sda]

For anyone watching this video one thing I would suggest is NOT to get into the habit of putting your gauges onto soil / dirty ground like in this video... hang them up with the provided hook well clear of the ground.. and keep them in a case when not in use.. some of that soil / moss can make its way into the fitting, especially the rear ones which although are only dummy holders on the gauges were face down in the dirt, when you reattach the hoses you might not notice.. this can then cause stuck Schrader valves, dirt into the system or hoses that don't screw on properly because of contamination causing a refrigerant leak until you can uncouple the hose and clean it out.

[@sergiomuniz9242]

it would be nice to see a video on charging a unit properly which includes taking into account different weather conditions and how to do it on various brands/ models and when to not add refrigerant. I think a lot of times techs add freon to avoid real problem solving and to save time. Include charging a unit that has no nameplate or chart.

[@alexc9777]

thank you so much, as a first year apprentice ...I come back to your channel time and time again for simple, useful information.

You're welcome! I do try to keep it simple here :) I leave the advanced stuff to AC Service Tech and Gray Furnace Man. Thank you for watching my videos, good luck with your career!

[@TONE11707]

Greetings from CA! I am a tech and have referenced your videos many times. I won’t waste my time watching anyone else’s videos. I recently ran into a problem with the suction line not getting cold resulting in the air not being cold. Pressures, Freon, voltage, and airflow all seem good. Do you have any videos with this problem?

[@WordofAdviceTV]

The best way to pinpoint the problem would be to use a slide rule. I use this one: SuperCool Slide Rule: amzn.to/2QdbcZx On the back side there is an arrows chart (system operating diagnostics) that helps a lot with diagnosing refrigeration problems. Unfortunately I don't have any videos on that topic though. If the refrigerant pressure (low and high side) are where they should be, then that is an odd duck.. Not sure why it would not cool then.

[@TroyDawes43]

ah cool.. Those yellow jacket gauges have the temp/pressure chart on the meter. Great video!! brings back memories of 1982 when I took ac and refrigeration.

[@imafatfatpig]

When feeding back in from high side to low side when disconnecting, you also want to purge your utility hose.

[@georgeliorga3769]

Right

[@brianflynn3210]

Tuck Godwin or buy a good set of guages and low loss hoses. Good video

Do you know of a link to a website to explain how to purge your utility hose like you mentioned? Thanks.

[@lilyak1408]

I just learned so much watching this video iv been taking notes and feel like I'm gonna be a HVAC pro in not time! Thank you so much

[@WordofAdviceTV]

Guys, in this video I made a little mistake and just want to make sure you won't do the same. When I put my gauges on, the unit was off. Usually I put them on while the unit is running. In the video I forgot to purge my hoses when I put them on which is especially important when the unit is off. When I then turned the unit on, the air that was in the suction side hose got pulled in. My AC is working fine but I am sure if I do that mistake a couple times I will have problems. Air is a contaminant in the refrigeration system so purging hoses is something that shouldn't be forgotten. If you have anything else to add, please do so! I do not claim that I know everything. A technician is always learning new things. Cheers! P.S. Also want to re-emphasize that refrigerant can be dangerous and your AC unit can go into an even worse condition if someone does not know what they are doing. Therefore if you do not have any background or experience in HVAC, I would highly recommend not dealing with refrigerant yourself. Stay safe!

[@chrisyuriar9751]

I would just say your head "temp" should be above freezing but yes ideally your suction should be about 40 to 50 and head "temp" about 20 to 30 °s above ambiant. Good video though and yes if you do not have EPA cert you CANNOT touch gauges unless a certified person is with you.

[@vonbrian]

what is the yellow hose for? thanks

[@WordofAdviceTV]

The yellow hose would be the one that you hook up to the refrigerant bottle.

[@elgringoec]

@@WordofAdviceTV Nice videos. I thought the EPA cert was just for buying the older refrigerants, and maybe for working by hire. The universal tech is easy to get though, hit up a local tech school and take a simple multiple-choice exam. (or 3 short ones) A small fee but it's good for life.

I watched a recent video by fox and family hvac and he dedicated a video aswell on not being so quick to hook your gauges up everytime you show up to a unit. To me that further soldifies your statement and practice on hooking up your gauges last. Great minds think alike or even better honest techs think a like!👍😁

Very clear and interesting the way you teach. However the more I learn, more questions comes to my head.

[@WordofAdviceTV]

Thank you! Yes, this is a very basic video on gauges. If you read the comments you will see that there is a lot more to it. That's why techs need to go to school for one or two years.. It's a lot of info to take in.

[@angelcollazo8328]

I just wanted to

[@mwiseben1]

I'm HVAC new upcoming student, this video is awesome and helpful!

[@michaeldowney8429]

Another thing that you should know is that purging should be done when you first hook the manifold set. By you placing them on and not purging them, you probably pulled in air and atmospheric moisture into your system when the pressures dropped on the low side.

[@WordofAdviceTV]

You are absolutely correct! Thank you for the reminder, I will make sure I leave the hoses slightly loose when I put them on. I don't always do that but now that you said that, I'll be working on my habits. Thanks again for the advice :)

[@sethfunkhouser7909]

Yup- moisture is in the air and moisture causes acid and acid in extreme cases comp failure

[@SnickasBah]

Michael Downey so that means you need a tank of refrigerant ideally to check pressures?

[@Rosiecast273]

My system is a 18,000 btu mini split And I’m In the Carribean- My out side temperatures are always 80-90 f. And the temperature we use on ac inside is always 62. Should the psi be between 35-40 ? My unit doesn’t have a high pressure port. Thanks

What about temperatures such as ambient, Delta T, superheat, sub cool or saturated temperatures?

[@paulgarland3288]

Good video. Noticed the high side shrader valve. Valve core needs replacing you can here the pressure from the cap more than normal 3psi. Also if the humidity is high and temps are higher. Suction will ride have seen up to 100 psi at 100 degree. Also raising head some by heat in house. Always do a Delta t when checking freon. Min (18 to 20 degree r22) (410a 20 to 24 degree) You check the return air temp and supply are temp and these temps above on the refrigerant above saying if r22 if return air 81 supply air should be 18 to 20 degree below around 63 that's 18 degree. 18 min 20 maximum. That's r22. Also when the humidity is real high and temps will make high super heat.

[@elleondejuda4681]

Very good tip man , I use run my unit did maintenance etc But i didn’t put back into the unit the refrigerant of the liquid line because of “ I didn’t know “ lol Thanks for the tip

[@drewsbenmad]

I would add that if you don't know or understand the temperature /pressure relationship of refrigerants you should not be checking any system. Understanding superheat and sub cooling is essential when checking your charge.

[@mikeryan6277]

It is essential, yet a very small percentage of techs use it while checking or charging.

[@dameionwebster3872]

You are a good instructor bro,keep up the good work 👏

[@rowdybroomstick1216]

If the valve is closed on the hose then all you need to do is open the high side while the low side is attached and it will suck that residual back into unit. Seems you added a bunch of extra steps. Because typically you would've already bled the line's, as you we're attached to the sealed system.

I enjoyed your lesson on how to use gauges. Some of your critics have not made much effort to communicate clearly (Oh did I just say something about real hvac tech) Thanks for your unselfish effort and good use of time. DO they need air conditioners in Minnesota?

[@cub3dgrafit325]

Personally for me whenever I hook my gauges up to the unit, I will have my ball valves open and my gauges closed shut. At about 8:19 I made the same mistake when first learning how to hook my gauges onto the unit, and I got a ‘handful’ of refrigerant spew out from my high side. The reason for this is because your ball valve in closed, not giving your refrigerant anywhere to go, so it spits out onto your hands. If your ball valve is kept open and your gauges closed, then the Freon will travel up your line giving you enough time to close it shut and minimalise refrigerant loss.

[@WordofAdviceTV]

Very good advice! Thank you for sharing!

[@BeautifulHomes83]

I see that R22 normal level is around between 40 to 50 ane When checking R410 look for that pink area marked R410A and between 40 to 50. Hey if HVAC technician works as you do, I would pay double what they ask for. I agree that who have no background about HVAC they should hire technicians however, your video will inform homeowners and able to tell if HVAC technicians are well trained or not. Thanks.

[@WordofAdviceTV]

@yesitsmonkey Glad to hear that you are more confident about your refrigerants now :) Thank you for watching and commenting!

[@mlong30]

By any chance, do you have a video where you find a Freon leak, repair it, then reinstall new Freon?

[@luicarlos882]

You are the best so far all video i watched

[@michaeldowney8429]

There’s a problem in using that set of gauges on R-22 as well as R-410a refrigerants. The R-22 refrigerant equipment uses mineral oil in the system, but the R-410a uses a POE (polyolester, synthetic) oil. If they me x, they have a tendency to become a mud-like consistency. You’re better off keeping it as a dedicated set for one type of refrigerant.

[@WordofAdviceTV]

Thank you for explaining that! I just briefly showed that I have 2 gauge sets but didn't explain why. I do have separate gauges for R22 and 410a.

[@rossy9549]

Actually you can mix the oils it was thought in the past that you could not mix them but you actually can. My mind was blown when I found this out all those years of carrying two sets of gauges to keep POE away from MO.

[@michaeldowney8429]

If that’s the case, then why do you have to flush line sets (or replace them) if your changing refrigerants ?

[@rossy9549]

This is from Emerson: When using CFC or HCHC refrigerants, POE and MO can be mixed. The exception is R12 that only uses MO or Alkyl Benzene Mineral Oil (ABMO) blend. HFC refrigerants can only use POE oil. If you get a chance read some of the retrofit refrigerant specs usually they have in there about lubrication if you have a mineral compressor to add POE in with it or vice versa POE to add mineral to help with oil return. Though the ratios are usually low. I mean no half and half crap but more like 95-5.

[@WordofAdviceTV]

Well that's good to know! Thank you for mentioning that! I was taught that I should not mix the two as well.
