Not too many people have a way of explaining electrical schematics , You Sir have a talent for this IMO. Thank You!!

As a first year apprentice, I can’t say thank you enough for this.

currently in my 2nd year of an apprentice program in a local college near me. This whole year is electrical and it was a bit confusing for me to read diagrams like this because my teacher never really goes too in depth with things and im more of a hands on learner , but this has made it sooooo much simpler. Glad my year one teacher that im still in touch with recommended your videos! :) Been outside on my own AC unit just getting a better visual for them and its pretty simple now. Thanks alot!

i am retired and my teacher was the same way ,,,,they are not all good at controls ! and to admit it is another thing ,,,,i love it when i am wrong this way i am hoping someone will correct me and i will learn something ,,,even a 68 years of age ,,,,just saying ,,,,,

Awesome video Brian! You’re very thorough and easy to understand. 👍

Excellent video. Thank you for taking the time. If I can get this....anyone can. You teach very well sir. Thanks again!

Thank you my friend for taking the time and effort in making these videos. It’s much appreciated.

This is fantastic. Thank you for doing this!

Man I'm glad you said something about the pressure switch typo! I sat there for like 5 minutes questioning if I had it all wrong when I was sure I had the down.

Good catch on the LPs and hps I've noticed little errors like that on schematics lol. You just shake your head

Great video. Very detailed.

Great great teaching these R my problems understanding a schematics. You explain in a way it works for someone with no electrical schooling I just learned as I worked so great great ways of teaching, & for the negative comments if you all know that much then why even watch. Thank you I'll continued to watch your videos, with some questions.

Great teacher a appreciated so much lam technician to the field this diagnostics diagram helps alot

Thank you sir! Great video!

Awesome video. For someone who struggles with this it really helps. Please do more of these on carrier and Lennox.

Sent to our DropBox for the guys. Thanks Bryan!

Great job on this. I am using this for remote learning with my HVAC high school students during this trying time. Thanks for sharing!

Nicely explained, keep sharing more and more lession

I super apreciate this!

I just LOVE “May be there” nomenclature!

Thanks for your endless lectures, really helps,can you please upload repairing and replacing compressor pistons,thanks

Thanks Brian... very helpful!

New subscriber. I watch your videos to help me understand HVAC and prepare me to enter the HVAC trade with a friend and enroll in APEX electrician school in NYC in April 2021.

Good video braking down schematic symbols, thank you

Thanks Brian for the excellent explanation.🙏🙏🙏

Thankyou for the greatest explanation sir l really appreciated

Thank Bryan another great video sr.

Thank you for sharing truly appreciate it

Its funny how for me as an electrical student, I learn more from HVAC guys than electricians LOL

One of the running jokes in HVAC is that it's a combination of all the other trades. Plumbing, electrical, light carpentry, HVAC (obviously), sheet metal, etc. 😁

I am a qualified Electrician now installing bms wiring systems. The Schematics before the dotted line confuses me at times. Been doing it for a few years now but i really don't take the time i should to understand the ins and outs of how the hvac side works fully. We use Trend mostly but also distec honeywell and cylon. This was a helpful video. Thank you

This was an awesome video. Thanks

I wish there was a hvac cert I could get by doing all your online vids. I completed an electrical apprenticeship school in 2015 in class 800 hour program. Would love to learn hvac too to add to my electrical troubleshooting and also to make me more valuable as maintenance manager at this resort I work at

You have explaind well, thank you Sir..

perfect job Man, God bless you

Thank you for the information is helpful

Thank you very much I learned a lot.

You are excellent Boss,

Very good explanation thank you

THANK YOU SO MUCH! This is a huge weak spot to create these diagrams, reading them is easier but not fn easy! It is like hearing Spanish and kind of getting it, but speaking.... much more difficult!

This video made me a better tech!

I'm a stationary engineer worked in a boiler room doing mostly mechanical stuff just started doing HVAC at a hospital I'm trying to learn schematics . Thank you

Hey Brian great video man really helping me out get better at this 👍 👏

Thank you sir, for some people your work is a beam of light in a moon free cloudy night. It would be better if colors of connecting wires, connectors are shown, if possible. Any way thank you.

Great video. Please do more like this on control circuitry. What path does the crank case heater take when the contactor is open. Does it take a number of paths throught the motor windings

New contactor only one leg opens.

@etherealrose2139

It'll take every single path back to the source. So yes. Power will not flow if L1 and L2 aren't connected so there must be one, or multiple paths, between the two. Even when L1 closes.... though because other loads are on that line, the current splits proportionally and the CCH will have less current draw due to such high resistance (though current will still flow through it, it's a misnomer to say path of least resistance. That's how people get killed.) It's simply that the heater is just a big resistor so not much current will flow through when the other loads are running. it is almost negligible when it does travel through the motors, not enough to create any flux. There will be a voltage drop across the CCH as well (with L1/T1 open) as it'd be in series with the rest of the circuit. Once L1 closes, everything is in parallel so the voltage is the same for each, the CCH will draw some amps just not as much but likely drop out of the circuit anyways due to CHS opening shortly thereafter because it either heated up the oil or the compression will quickly get it heated up once running.

This is excellent video. If you were in Dallas area and offered school, I'd take it.

Very Very Useful Sir

VERY USEFUL THANKS

Very nice explained thank you sir

Good video. I would like to point out that all modern romex has 90c rated conductors so it could be used for this installation.

Thank you!

love you're videos been a fan for years but am having some low voltage issues on a carrier package unit trying to follow the wiring on the schematics but its crazy do u have any recommendations on how to get better at following and learning schematics

7:48 You can tell it's open on rise because imagine if water were rising beneath it, the beam would rise and open the contacts.

Thanks for your nice video. I hope you continue this as a series esp going to rooftop units as well.that will be very helpful. What is your trutech tools discount code?

Thank you! It was very helpful! First year female hvac apprentice here 🙋🏽‍♀️ appreciate the video but damn you talked way too fast and it was hard for a newbie like me to keep up but I did learn so thank you!

12:18 in your video you said you can look up a ptcr on this page and i can't seem to find it. any chance you can put it in a link. thanks and have a blessed day

was going a bit quick but great video.

Thank You

Thanks 🙏🏾

Great video

Greats!

Ur correct u have to scan what's on the schematic diagram this is for an account but I did it on radar the first thing I look is input

Playing this reminds of the scene in The Matrix when Neo gets his first Ju Jitsu training session. Unlike Neo, I'll have to do it several times before going up against a Carrier.

Hi HVAC School, Can you please do a three-phase wiring diagram lecture for industrial refrigeration? A lot of people work in non-residential settings too!

Thank u

good video

Why wouldn't they use a single pole contactor so you can have power to the crank case heater in the off duty cycle? Please and thank you...

anything on circuit boards , other than if you have power to it and out of it its good ,,,,i think all teachers seem to use this as an explanation to those boards ,,,,thank you

good job.... 40 years in started in1981

Thanks boss

Thank pls more on the pcb

Wow that's a lot to understand

My goal is to identify the functions of the devices in a given circuit diagram? Or spoken more general. How can I lean this general skill? When do I see a random circuit diagram in all kinds of electronic fields that I can recognize the devices and their functions? What is the best strategy to acquire this skill? Do you know good information recourses specially designated to acquire this skill? I do not want to handcraft things on my own and I do not want to study at a university to acquire a bachelor's degree in electrotechnology. I just want to be able to read more or less the circuit diagram. Thank you in advance

NM Romax is normally used in one- and two-family dwellings, and certain multifamily dwellings. NM-B is what you will see when shopping for NM cable, which is rated for 90 degrees C (194 degrees F).

good videos

HVAC School I was wanting to better understand why Carrier has a Start Thermistor in parallel with the start capacitor and start relay. Thanks in advance!

thank u

Maybe you can do an advanced version. That would be awesome

month and a half into the trade here. All this stuff is so alien to me i have no idea how to understand this stuff. any advice??

what is the "E" that fell over that comes off of the OFM?

On my 1983 furnace wiring diagram, why is there one set of the air combustion (inducer) relay's normally open contacts in parallel with my fan control/limit-- the old style fan control type, that is? Why would the diagram say that call for heat turns on the blower right away and not let the fan switch do it in it's on time when it heats up? And it doesn't list like it's an optional wiring in the notes anywhere? But I'll bet if I go look on the furnace that there is no combustion relay across the fan switch so why is it in the diagram? It's a Heil diagram in the manual so why would heil print out a faulty diagram? I'll have to check to see if it's on the inside front cover panel also which I think it is so why would they do that?

8 month in as a service tech and still struggling to read schematics when no legend available. Are the symbols for field splice, control/field wiring etc universal for all schematics?

They use a single pole contractor simple for a path for the crank case heater..

You have explained the schematics and symbols very well but you have not explained how the power flows during start of compressor and fan and when it switches over to run bypassing the start capacitors.

سلام سپاس وهزاران تشکر از همه زحماتتون.👍...وهزاران هزار 👍.......جناب مهنس محترم امکان ترجمه زیر نویس بفارسی هست....ممنونم....

Did anyone else noticed the LPS and the HPS are different symbols on the Connection Diagram compared to Ladder Diagram. I believe the symbols on the Connection Diagram are correct. They are both normally closed switches. The LPS opens when the pressure drops while the HPS opens when the pressure increases. But, on the Ladder Diagram, I believe they are switched. Or, am I incorrect?

Brian I need help with RTU Schematics

All wiring diagrams BMW from 1998 to 2022 are in this application android (Bimma EWD)

Hi people, does anyone know a page where i could fin electrical diagrams of an old machine?, the AC is like 20 years old. Is the York sunline 2000.

Thank you for this explanation, I don't know why some people make dislike

Fast but good

If you see mistakes on these schematics, do you ever contact the manufacturer and inform them of the mistake?

Find more details => homewiringdiagram.blogspot.com/2019/01/3-way-light-switch-wiring-diagram.html

slightly differnt from radar school... capacitor = --l l-- and not -l(-

new susbcriber bro here. I did not study about this even though I'm an aircondioning and refrigeration technician just a small unit not like hvac which its units are huge compared to window type and split type but I'm still learning do you agree?
