AUTOMOTIVE HOW TO: A/C SYSTEM DIAGNOSIS FOR BEGINNERS

This is a beginners tutorial on how your automotive (134a) air conditioning system works. Hopefully this gives beginners and diy owners an idea of how their system works and how to diagnose certain problems.

Been a gear head all my life and im a licensed stationary steam engineer....you just explained thermodynamics and dianostic examination better than a 5 thousand dollar class lol. Very good job man. You should consider teaching.

As the owner of a 20+ year old car who likes to do his own repairs, this explination is PRICELESS! The more things I repair successfully, the more confidence I get! This video provided me with information that will no doubt help me when my system needs some tlc.

If you made a whole learning series like this, I would openly pay for it. No BS, better than tech school lol

Love learning anything about cars, dream is to own a shop one day. People like this guy who willingly teach, the best people ever to support.

One of the best explained walk through ac videos I've ever seen. Fantastic job.

[jettrink]

Thank you for your speaking loudly and clearly... so many people these days just mumble. good video

[Vramirez]

Man! Seeing this video helped me catch an issue the easiest way I could learn. Thank you!

[rubenleyva-jmenez]

I’ve seen plenty of A/C videos and this one is by far the best one, you explain everything really well, keep up the good work.

3 years later and I'm just now seeing this. Fantastic educational video!

[Pontiacdreams]

This is the gold standard as far as I’m concerned. Couldn’t be clearer. THANK YOU!!

[joeytongue]

This gentleman did a great job on this video. If I owned a auto shop, I would require my techs to watch this. Very well done.

[ephraim.]

This guy knows his stuff. Hands down the best YouTube video I have seen regarding auto AC troubleshooting.🙌🙌👏👏👊

[cztexas]

This is the best video on how the car air-conditioning system works! Thank you so much for this.

[maxcrss]

Thanks for this. I took my car in to a mechanic to see why my AC wasn’t working, and it turns out my entire system had corroded. I didn’t understand what that meant, but this video really helped me visualize it and look into what parts I might be able to replace for a stopgap

Thanks man! this helped me diagnose a bad wire that was intermittently turning off the fan. I noticed the high pressure would increase all the way beyond 300 as I filled in freon, even with 4 oz in the system. I thought it was a clog or something, thought the expansion valve was bad. If I just knew a little foundation to the AC system I would of known instantly the fan wasn't cooling the condenser, duh!. Thank you!

[outofthinair]

The best explanation I've seen on Youtube. I'm now going to troubleshoot my AC system with confidence thank you.

[takismantas]

Outstanding video with clear explanation on auto a/c basics. It would had been great if you had demonstrated the scenario of overcharged systems, which is something common. I have found that a lot of people just "blindly" add R134 when their a/c does not cool sufficiently.
I hope to see a part in this series going into a little more advanced scenarios. Thanks for your hard work.

[tonyreyes]

One of the best explanations on how the car air-conditioning system works. Thank you so very much for sharing your expertise. I really enjoyed watching the whole video. All the best and best regards.

[pro-lifik]

By far the best and most in depth explanation I've found yet. Thank you so much

[bills]

Excellent video that allows the novice and the back yard mechanic to understand AC components and exact problem and repair. Nicely done.
