How to Remove (Recover) Refrigerant From a Running AC System

[@kennyjohnson4411]

Yes, another amazing video from HVAC school. I love this channel ❤

Another great video. Love the live graphics👍

[@resurgensix]

WOW these new vids Bryan is producing are ready for prime time! I can watch them again and again to imprint these processes.

[@RonNL1030]

This turned out to be very practical to me. I’ve been in that situation before. Now I know an easy and effective way to do it. Thank you.

[@hvacdoc]

What application are you using to make these videos? They come out awesome every time!

[@michaelstaley9979]

Great video. Just finished watching videos similar to this on ac service tech channel. Keep up the good work.

[@elgringoec]

Great thorough explanation of the process, while being quick and concise! The animation detail is nothing short of amazing too, perfectly matched to and illustrative of the information content. Really gotta hand it to you, it's professional grade production. And I can definitely perform this operation much more quickly and efficiently after reviewing this. 👍😁✌️🏖️

I just discover the HVAC school app !! Wow thank you! And thank you for your vidéos this is helping me a lot at school and in my summer Time job !! Great job !!

[@davejohnsonnola7908]

Great info and presentation. I would vote for lingering a bit longer on the more salient points that may be passed over by our short attention spans.

[@falleruen]

I watch 5 other videos and this was the best one

[@FabricioValdez-si1pk]

Amazing video. Thanks for sharing HVAC school. Saludos from Wisconsin.

video tutorials like this are great. huge help thanks

[@roberthaggerty5720]

Another 6 minutes of great knowledge Thx.

Many scroll compressor AC units have a low side suction line cutout switch for low suction pressure. It may not allow a compressor operated recovery below a low side suction pressure of about 55 psi. This still gets most of the refrigerant recovered. If it is the first time you encounter this, it might scare you when the compressor shuts down making you think you damaged compressor. Don't worry it is just the low pressure cutout switch doing its job. You might want to stop at about 60 psi suction pressure to prevent the cutout switch activation.

Top Notch 👌🏼 great demonstration as always

[@Oz_is_on_fire]

You guys are awesome! Uppin’ my game with every view.

[@Wdbx831]

Top quality education - who knows, maybe they will be eligible for continuing education credits.

[@acrepairnearme]

Great illustration

[@OcRefrig]

Wow, Very cool Graphics ! Very Well done. 👍 If u don’t my mind me asking , What Program are u using to do a Video like that ?

[@daniellundquest8252]

Hook up a ball valve on your core deppressor. Close the valve and the high pressure refrigerant will go into the tank and clear your hoses… dependent on the temp of the refrigerant, ambient temp, and the temp of the cylinder

[@alohadoc1]

How would this be done with a mini split? I need to remove some overcharge

[@1984juant]

Great video.

[@MemeKing44]

When you recover the second time and refrigerant is still in tank do you repeat the same process, by first vaking down? Or do you not vak because you already have a vak? And can putting a vak on a tank with refrigerant mess something up? Seems like the vak pump would pull refrigerant toward it into the vak pump and empty your tank I to the vak pump is this wrong?

[@michaelcostello6991]

Do all small split units have access to suction and liquid lines with hoses ?

[@davidkarpen5686]

While doing this. What prevents oil from leaving the system as well? And would that damage the compressor because if the correct oil was added from the factory and an imbecile overcharged it, if oil came out with the excess refrigerant, the system would now be low on oil? Correct?

[@lebenitj]

5 grams is not an issue..

[@TheDirtyd863]

Awesome video thanks Brian.

[@valeriesmith4642]

Hi, How long does it take to remove the freon tso one can repair the unit?

[@nation1280]

Good information, amazing video

[@vincenzolabarbera8964]

Is this the same process for a small window air condition? I have a 10,000 BTU window air condition and would like to remove the Freon

[@hubercats]

Great video!

[@kevinjeudy5607]

Great videos. Very helpful.

[@mikecasey7505]

What software is this?? This is amazing stuff for training!

[@xXRAWRXx5]

I’m in school for this and just learning so excuse me for asking a dumb question but if this was a liquid recovery, at the end you said open the hand valves to allow the remaining refrigerant back into the suction side. How is this possible to return refrigerant in liquid form to the suction side?

[@thecurious6721]

Open slowly and let the liquid to vaporize and scroll compressors handle liquid better than reciprocating compressors, there are no valves to break.

[@Homestead_Adjacent]

How does pulling to a vacuum harm the compressor?

[@davejohnsonnola7908]

Many scroll compressors are set up to "disengage" the scrolls below a certain pressure. Not made to pull system into vacuum the way older style reciprocal can.

[@Homestead_Adjacent]

@@davejohnsonnola7908 there is a clutch? My mind is gravy.

[@davejohnsonnola7908]

@@Homestead_Adjacent more like a mechanism that separates the scrolls and bypassing the gas

[@mojo9288]

There are several ways a compressor can be damaged when it is in vacuum. Compressors are cooled internally by the returning refrigerant vapor from the evaporator as well as externally by the air being drawn/blown over the compressor from the condenser fan. Without that cooling a compressor will overheat and the motor windings may be damaged. The refrigerant vapor and oil within a compressor act as electrical insulators. When in vacuum, the compressor does not have that insulation and an arc may occur inside the compressor and cause a condition called terminal venting. The compressor electrical terminals may blow out or the insulators around the terminals will be damaged and cause a leak. Most compressors will handle running in vacuum for short periods but they cannot operate in a vaccum for extended periods. You will see in some literature that warn never start a compressor when it is in vacuum. Low pressure controls will shut off a compressor before it goes into vacuum but not all systems utilize them.

Thank u so much .Great video

Hi I have questions Dose this cylinder consider as dangerous goods how can I get the MSDS as I would like to import it to middle east Thanks

[@mrgreen9086]

I've noticed that alot of these models feature a txv, are pistons no longer being made or phased out?

[@joelescalante2616]

depends on the region you are in Florida it seems like everything has TXV now. I am in NC and I see pistons everyday even on brand new systems.

[@mrgreen9086]

@@joelescalante2616 that makes sense thanks

[@anthonybarragan1687]

And if there is refrigerant in the tank, can you still use this method?

[@Thanos-ic8ki]

will this also work with r22 ? ?

[@centinelarefrigeracion8834]

Hi , thanks for share this

Amazing

Hvac school app
