[@sprint48219]

If you have a nonworking system most of the time the refrigerant has already leaked out all you are doing is creating a vacuum so that you can reinstall refrigerant without having air in there to mess up the system If it won’t hold the vacuum then you’re finding a leak under vacuum when you have to look around and see if you can spot where you have what looks like an oil stain on a line or something or possibly use dye and a black light If you can’t find anything let it run and let the water drip out of the evaporator and hit that with the black light and if you see the dye in the water then you got a problem because most evaporators are an SOB to change Scotty has forgotten more than I know but I have picked up a little over the years Keep it up Scotty !

[@numchux2]

Small correction! Hvac guy here! The compressor won't die because of too much pressure, as your pressure fluctuates all the time...what kills it is liquid not saturating into a gas by the time the refridgerant reaches the compressor, which is caused when you overcharge the sytem! It has too much liquid to process, and once that liquid hits the compressor it will likely kill it! The compressor is responsible for turning Low Pressure Medium Temperature Gas into a High Pressure High Tempurature Gas, the heat is then rejected into the air turning it back to a liquid through the condenser, goes through back to the evaporator and starts transitioning into a gas again by absorbing the heat from inside air :) Good video though, and I would recommend anyone who doesn't know the refrigeration cycle and P/T Temp relationships etc to do it this way, can't go wrong!

[@gort400]

Question. How do you take the refrigerant out first, to then put in the factory amount?

[@donvonschitzinpantz2]

Scotty has a recovery system, I seen it in some of his videos, but if you are a DYIer and don't own a recovery system your refrigerant could just leak out by accident "hint hint." 😉

[@robertborchert932]

Handy primer on using a manifold gauge with the AC system, Scotty! By the way, it isn't 30 pounds vacuum, it's 30 inches! Been working with vehicle AC for decades. My take on r-1234yf? It's a real pickle, stupid expensive and hazardous material, more flammable than you think. Regarding the high side, one must be very careful when the compressor is running, AND you must be mindful of the VALVES on your manifold. You can interconnect the high and low side if both valves are OPEN. If your fill line, the yellow one, does not have a safety valve you can send high pressure refrigerant toward that wee metal can! It isn't designed for that pressure. As a professional, I must diagnose the system in operation. Thus, I monitor the high side pressure to verify the compressor and TXV operation. Handy trick! You can check the high side valve if your quick disconnect is working properly. Those knobs work in reverse from the way you think they do. As the QD is fitted, it locks atop the service port and seals the connection. Rotating the valve clockwise depresses the Schraeder valve on the service port. There is a "dead spot" as the knob is operated. When completely turned counterclockwise, the quick disconnect is shut off to the hose. I apply vacuum to the manifold, and verify (with an uncharged system) that the Schraeder valve will hold a vacuum when seated. This question has become moot with R-1234yf. If I had a penny for each time the leak was the valves, think I'd have a real bankroll by now. Nasty stuff.

[@putteslaintxtbks5166]

What about oil, some cans say they have oil in with the refrigerant?

[@coarsegrind]

Scotty are you advocating venting an existing that is low on refrigerant and then evacuation via vacuum, or only evacuate on an almost empty system where the low pressure protection prevents the compressor clutch from engaging? People don't realize that vehicles "air conditioning systems" are not true air conditioning like your house. They are in fact High temperature Freezer Systems because of the heat load and poor insulation of a vehicle. True air conditioner would never cool it for comfort in a vehicle.

I bought a valve system for refrigerant when I saw someone had thrown out a huge ice cream fridge and I plugged it in but it refused to cool off. I figured it was worth the money to see if I could fix this $800 freezer. It worked! Shortly after I bought a used car and it needed to be recharged so I did it myself after buying a $10 can of refrigerant. They are cheaper if you already have the valve part. Now my car puts out an arctic blast! Pretty proud of myself and have a lot of extra cash in my pocket.

Thank you Scotty! Loving your work. Learning so much 🇨🇦❤️

Scotty I'm so glad I found you mate!

[@roguethinker6284]

Hi Scotty. Great video. I'd love to do this myself but what if there is still freon in the system?

[@donvonschitzinpantz2]

It could just leak out by accident "hint hint" if you don't own a recovery system.😉

I'd love to go riding with Scotty. If he can move his legs as fast as his hands I bet he's fast!

Thank You Scotty For Training Us.

Been watching your videos and really enjoying them. Have learned a lot. Recently we bought a used Toyota Camry (2014 with 44,000 miles on it) and noticed that the mpg was not what I thought it should be. Was running 22mpg! In one of your videos, you mentioned that a dirty air filter might be the cause of poor mileage. You nailed it! Replaced the filter, and now it is up to 27mpg! Thank you. BTW love the car

This method is the exact method id say most mechanics actually use when doing AC work, just with fancier more expensive equipment than can diagnose issues with the system itself.

[@oldtimefarmboy617]

If you are going to go to all that trouble, replace the schrader valves before you hook anything up. That way you do not need to worry about the valves leaking when you are finished.

[@Keifsanderson]

If you're replacing the valves, I'm guessing you'll need to run the vacuum pump for another 45 minutes before filling? Reason I ask is that you must evacuate the system before removing/replacing a valve, right? And in order to access the valve, you have to disconnect the vacuum pump, right?

[@oldtimefarmboy617]

@@Keifsanderson Scotty usually recommends evacuating the system in case like this to prevent any refrigerant from escaping into the atmosphere. So all you have to do is run the evacuater until the pressure is zero, stop, replace the schrader valves, and then continue with the evacuation like normal. If the pressure is already zero then just replace the schrader valves at the get go and then evacuate. Then when you refill the system you will have brand new valves and not have to worry about the valves leaking after putting in all that expensive refrigerant and loosing it or starting the whole process over again.

[@sarasata]

Seems it would be a lot easier and cheaper if I can buy that spray can you were spraying in the vent in the thumbnail. Where's the link for that?

[@AlecShernAPS]

What does the old refrigerant go into before you refill it?

[@deniswauchope3788]

That's what I was wondering too!

[@philipzivnuska7321]

That's my question too! What happens to the old refrigerant? Where is it stored and how do you measure it?

[@jacobsebastien3910]

It's a secret.

[@robertt9342]

He’s just being a ahole and pumping it into the environment.

[@rodn9338]

what do you with the old refrigerant that may be in the system. is having it evacuated by a pro the only option?

I never have luck with Autozone rentals on these gauges. Usually are missing fittings or seals. Vacuum pump was a complete mess and would over heat and stop. Its cheap just to get a harbor freight set.

[@ham5483]

Funny you mention this, i just borrowed these gauges twice, after i was done pulling a vacuum i had a loud hissing leak on the low side valve on two cars, broke each valve and had to spent 26 bucks to replace them, never again.
