AC Avalanche - Auto Air Conditioning 101 Made Easy

This video represents a "Typical Auto Air Conditioning System - How It Works" as well shows the potential problem of over-charging systems with TXV Valves. Our solution at AC AVALANCHE is to use SMART CLIP Technology for the correct fill!

Every new mechanic who's delving into the world of automotive AC diag and repair should watch this video. Straight to the point and very accurate.

That was probably the most simple, concise and helpful explanation I have ever seen.

[tootsp]

that was so simple, slowly, accurate, clearly was made to make everyone understand
WOW factor

[twoscoops]

Seriously educational. Remarkably concise and helpful, I had no idea how the system worked 5 minutes ago (well, 6 if I'm being honest about skipping back a few times), and now I know exactly what's going on. Thank you!!!

Excellent graphics and explanation of the A/C system. Thank you!

Outstanding video. Thank you. I've learned plenty on this subject thanks to YouTube. This video, however, has a couple additional features that help even more. First, the identification of liquid versus gas with bubbles or arrows in the animation is great. This helps with visualization of the changes that occur, where they occur. Second, the effect of the reading at the sensor on the flow allowed by the expansion valve (I have an orifice tube on my vehicles) and then HOW overfilling can occur. That, I think, is the first time I've seen these features included... quite valuable. Thanks again. My guess is that the smart clips substitute for having a thermometer in the vent? Someone commented a year ago that your product, with the clips, are sold at Autozone. I shop there, and do not recall seeing them. Will look for them, specifically, next time.

It helps me a lot to understand how the air condition system works,
the illumination was pretty detailed and clear

[jada]

Thank you so much for taking the time to do this. That explanation was perfect.

I agree, one of the best diagrams i have seen, plus the TXV valve problem i had experience is here, thank you Mr Avalanche.

[andrewberner]

Amazing in auto mechanics in high school and this explains so much

[kaylap]

this is really helpful
it taught me more then my teacher

[MosportRacingSchool]

Thank you, that's easy to understand. I'll be troubleshooting the AC on my Sube Forester next week.

This video is so nice it clearly explains it all

[prudhvivenkatch]

this is wt ive been looking for. thanks. :)

[thecreator]

well done very clear clarification about it thanks

[shadows]

Correct me if I am wrong but isn't the job of the condenser to cool the high-pressure gas as the air traveling through the condenser releases the heat through the fins of the condenser (the same as the radiators job is to remove heat from the anti-freeze)? Essentially condensing the gas back into a liquid as it cools off thus the name of the component (Condensor). The refrigerant enters as a hot high-pressure gas and exits as a cool high-pressure liquid, the job of the expansion valve is to simply lower the pressure of the cool high-pressure liquid as it enters the evaporator where the chemical change once again takes place and the process repeats itself.

Thank you, it is very helpful as I had a previous experience in split and window type units!

The TXV has only one function and that is to control superheat, ensuring that only vapor goes back to the compressor, it does not control pressure or temperature. There are two forces trying to close the TXV (evap pressure and the superheat spring) and one force trying to open it (superheat aka power head). Low side pressure will increase or decrease depending on the refrigerant charge, with more liquid pressure the refrigerant is moving faster through the evap and not removing as much heat.

Very informative video easy to understand

[candicesexil]

my A/C is mess up now I have a better clue how to fix it thanks your really help
