I just graduated from a technical college in hvac and am still confused in reading schematics. The 26:46 minute point of your talk clarified something that has eluded me until now. I appreciate the pictures that go with the schematics. Thank you Ron!
Finally a video to teach tech's the basic from the beginning. I find that many tech's starting in the field are incredibly weak in the understanding and implementation of HVAC circuitry. Through no fault of their own, not much time in the understanding if wiring diagrams is taught but hopefully this will break that trend.. Thanks'!!!
Thanks again so glad I got my universal hvac certification first. Im gonna know this well before my interviews. Thats why they pay you guys.(for what you have in your head) and I will present this in my interviews. Like a Champ thx so much.
I am very impressed with your presentation, narrative style, and content! And I have seen hundreds of presentations in clinical setting as well as graduate school.
This is helping me so much in not becoming a junk mechanic. Thank you so much for this. Please dont stop posting helpful videos like this. I will pass this on to the next potential technician in training who is eager to learn the right way!
wow i'm new in the field still studying and this one video has made me understand schematics better then before. You explain everything so well appreciate the video.
Ron you are changing lives by providing knowledge that your passionate about.. Mason Cincinnati, Ohio.. Between you and Graythefurnaceman I feel a little more competent in the nomenclature.. THANK YOU !!
Thank you very much, i am learning a lot through these lessons, i have just started studding air conditioning and refrigeration,you really explain things very well,thank you....
Thank you very much, my great teacher! I learn a lot from your instruction. You give very clear clue that most service tech might need. Please keep continuing ...
Outstanding video! Thanks for sharing this I'm getting ready to go to HVAC Training on June 1st,2015 can't wait for the class especially the hands-on training. I'm ready to get started with tis new career. Thanks again Ron Walker.
Very through. Thanks so much. Your are making hvac learning fun for me. I am once again excited to learn and for some reason absorbs the words that are coming from your year of experience. I have recommended you to quite a few of my fellow classmates struggling. Thanks Ron.
"Normally open" or "normally closed" on an electrical circuit can be more easily remembered by "fail/safe". If power fails the circuit is safe. This is the safest condition where nobody gets hurt.
Do you use latching mechanically held contactors with dual coils in HVAC?? I got the bosses son for a tech a couple years ago. He used to work at a frat bar, and has no aptitude for HVAC at all. He wired the start run caps wrong 3 times, and the unit had both a schematic and a simplified color coded idiot's wiring diagram right inside the access panel. One of the motors was rattling the windows on the house, so I went up and straightened it out. I did a lot of industrial process piping, instrumentation, automation and motor controls. I am disabled now and work part time on audio equipment. I have worked on a lot of foreign made equipment with non-standard schematic symbols, and weirdo color codes. I worked with a lot of electropneumatic controls too, as well as optically isolated controls & PLC, as well as the old GE transistor to transistor relay logic. I don't miss that one! YOU ARE A GOOD INSTRUCTOR! I did not really learn anything new, but you present the material very well.
Thanks for the video! I'm learning a lot from this. One question though: for the window AC. I'm confused about the hammer looking switch. So in this case, there are only 2 positions that it can be in right? 4-1 = OFF position and 4 -2/3 = ON position. It can't be in just 2 where only the fan is running? Or just 3 position (even though that won't do anything, it'll just refrigerate but not have any flow) I got this question on a test, shouldn't there be a point of connection in between 2/3 for them both C and FAN to operate?
Ron, I just finished this video and it is quite good. Have you done the videos that you mention about walk in cooler, freezers, etc. I went to schematics Part 2 and it seemed to be a repeat of parts of this one. Thanks
Thanks a lot Ron for this useful teaching. I appreciate it, I’ve one question for you I'm a mechanical estimator in Canada, generally I use to engage an HVAC contractor to provide me a lump sum price for a complete installation, however, due to the downturn in the oil and gas industry I’m out of work and looking for estimating jobs in these days and most of the employers are asking estimators to know HVAC estimating, after watching your videos I thought you are the guru of HVAC, what would be your advice for me how to learn HVAC estimating?
Thankyou very much sr. i like it tooooooo much. but i have little probleam. that is ur langwage.but i go 80% theory's. sr.can u suggest me that how to i can convart in hindi langwagw. it's ammging. i already downloaded it. THANKYOU SR.
thanks you so much for your explanation , just I have a question. how why start to diagnose the mains prblems in hvac R where and how to start to Chek , main power capacitor or contactor

You are welcome. That is why I do what I do!!
You still a tech in the field?
Hi Ron,
Thank you very much for taking the time to publish your videos.
You've helped me tremendously understand schematics and ladder diagrams.
Definitely, this is the best explanation on reading and understanding schematics video on RUclips. Thank you!!!
I love this video I am a HVAC tech for 8 years

Mahesh Patel Thanks Mahesh, you are one of my best students!
You are my Inspiration Thank you Beautiful work
Ron thanks, I appreciate your dedication to teaching others.
Thanks, i appreciate all the action and the way it is done, and all the teaching was very understanding.
"Normally open" or "normally closed" on an electrical circuit can be more easily remembered by "fail/safe". If power fails the circuit is safe. This is the safest condition where nobody gets hurt.
Sometimes compressors are labeled CSR or common start and run and it does matter if you hook them up wrong.
very good, thank you. I have been away from the field for a year, thank you for the crash course.
omar mario You are welcom.
Very good explanation and demonstration appreciate you thanks 👍👌💐

thank you so much , this part I am looking for

thanks mate your explanations are excellent, great job.
Well done!
Really great video
Keep it up
thanks for your hard working keep it up.......
Thanks a lot for this useful training. I appreciate it
Thanks Ron greetings from ARU
Is the contactor coil considered a power consuming device in the 24V circuit.
Great video! How and where do I watch more on the schematics? Where do I get part 2 3 and 4? Without buying all the videos??
Ron, I just finished this video and it is quite good. Have you done the videos that you mention about walk in cooler, freezers, etc. I went to schematics Part 2 and it seemed to be a repeat of parts of this one.
Thanks
*****
Yes I have, as part of our paid training.
thjis is very cool and give me more info about the schematic diagram and your instruction is very good the way you discribed it. thanks
Great video. Great teacher!
Goru Minosyan
Thanks!
I've been studying circuits and discovered a great website at Gregs Electro Blog (google it if you're interested)
Thank You for the knowledge 👍
Can you give me the link to the part 2 hour long session to this video if there is one please.
Thanks a lot Ron for this useful teaching. I appreciate it, I’ve one question for you
