AC Avalanche - Auto Air Conditioning 101 Made Easy

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

Hi AC Avalanche, I have a Chevrolet Sonic 2015 the the problem is that the high pressure pipe is cold and the low pressure pipe is warm and the A/C does not cool, what could be the problem? i have to recharge the system each month.

What is the effect of ambient air of the outside temp .. on condenser as the radiator fan is to cool the refrigerant ?

what are the tubes called? the tubes the air actually flows in? and how do you order them

Thx incredible

👍🏻nice

Thank you

Absolutely excellent video.

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

Had one question in my car ac cooling down after running 50 kilometers. AC Cooling fine in idle and till run up to 40-50 km. Can you suggest the solutions.

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

Can you use a 7 cfm vaccum pump on auto ac or do you need a 2 cfm?

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.

What is the temperature in the condenser?

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.

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

Help my a/c system has orifice tube, accumulator canister and expansion valve. So which one is clogged? 1990 Chevy van 30....................

Yea

VFD of a compressor , can be used with orifice tube or expansion valve ?
Or it doesn't matter ?

amazing

Where to charge compressor oil..and what will happen if oil charge through LP service port

SO There are 4 Main Components.
One for Increasing pressure. (Compressor)
One for Decreasing Pressure. (Expansion Valve)
One for Increasing Temperature. (Evaporator)
One for Decreasing Temperature. (Condenser)

so nice video

Good video

Does anyone know about DOOWON AC COMPRESSOR ?
IS IT GOOD AND LASTING??

Good good

hi
in high side gauge..how much psi it should be ? to see the level of the gas?

Thank you sir ji.

Bahut achcha laga app ka video ac ka work thank you.

Hello ...i am from iraq ... my probem is when the RPM is more than 2 the AC is disconected ...in your openion what i have to do....thanks

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.

thanks a lot

This video is so nice it clearly explains it all

Great video!!

Thank you very nice video 🌹👌😁👍

can you explain the AC of electric vehicle like TESLA?

Thanks sire

I have a problem on my 2005 Kia Sportage . Whenever I turn my AC on in about 3-4 mins I have blinking drive light until I turn the AC off. Any idea what problem I might be facing

Wait why does the low pressure liquid refrigerant go through the evaporator and then turn back into a gas? Is there some sort of reaction in there?

Great video

Nice sir

Thank you

I feel like i kno ac now lmao

Thank yoi

why Gas need to be compressed for going to condansor?

Thanks u

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!!!

You have Forgot to say that, the Compresser is Runned by the Serpentine Belt of the engine

Marami akong na tutunan nito sa video

Good stuff it helps in my studying
