You're not subtracting the weight of the can first.

[@bobbytables4305]

There's an easier way to do this. As long as your scale isn't super cheap it should be able to show a negative value. What you do is you put the full can on there and tear that amount. Then whatever you figured out the difference was that should be the negative value that will appear on the scale. And then you know you've added the right amount.

[@RwC42]

As an SAE Certified automotive air conditioning tech I would like to point a couple of things out. First, if you run your vehicles AC for approx. 10 minutes EVERY MONTH, you will lessen the loss of refrigerant. One of the reasons automotive systems have oil incorporated with the freon is to coat the inside of the hoses used preventing freon loss. Also, if you insist on vacuming the system down make sure you replace the oil that you vacume out or you will risk burning up the compressor and the will be nothing to seal the inside of the hoses. And remember to purge BOTH gauge lines, not just the line coming from the refrigerant supply. Just a couple of helpful tips.

[@mitchellcrane9809]

The information you have stated is correct except for one thing. System oil is lost when you do a refrigerant recover. Doing a vacuum on a atmospheric system does no remove oil. The oil that comes out during recovery comes out with liquid refrigerant.

[@tommurphy4307]

application-designed systems use hard lines- cheaper uni-fit systems and kits utilize hoses. that means the froil is used exclusively to lubricate compressors.

good advice about Autozone loaner equip. Vacuum pump and manifold setup can be rather pricey for once in a great while diy purchase. Also, be aware that if you have any sizeable leaks, they should be fixed before pulling a vacuum on your system otherwise you will pull oxygen and moisture in under that vacuum (nitrogen is normally used to pressurize and test for leaks). Minimal amounts, the system drier will take care of.

No, he is not right. R-134a has 0 Ozone deplation potential.

To put it into perspective: a full load of this refrigerant has the same greenhouse effect as driving a 2006 Honda Accord i-VTEC 2.0L for half a year (3783 km, 2350 miles).

Many scales will weigh in the negative. If yours does, you can put your can on the scale, tare it or zero the display, then, in this case, watch for it to read -210g. If it's a cheap scale, when using it to read live data like this, it's useful to press very lightly on the scale and let off before reading the weight. They're designed to set an item on and weigh, not to detect momentary change in mass. If you have a neighbor that sells "pharmaceuticals", ask to borrow their scale, it's probably high end 😂

My 04 Toyota Siennas AC was blowing warm. I purchased a can of AC Pro complete with hose and gauge for $50 at O'Reilly auto parts followed the directions. It didn't take the whole can and has been blowing ice cold for three years now.

[@F8Tributo]

Another pitfall is if you keep recharging a system with the typical refrigerant-and-lubricant premixed cans from the autoparts store. (Without first collecting or purging the contents of the system) If/when the gaseous refrigerant leaks out, the heavier lubricant can stay behind. Next time you recharge with a premixed can, you're adding even more lubricant to what's already there. The lubricant itself is not compressible when there's just too much in the system, and it pools up in the compressor. Eventually, the compressor can stall or even break, if it's forced to compress a diet of mostly lubricant. That's another reason why the system needs to be evacuated properly, and refilled per spec.

[@Airon79]

Or therefore a lack of lubricant ; depending on which way you hold the can during charging . Should one shake the can prior to charging ? Do they still teach to heat or chill the can prior to charging or has that proven not to speed things up ? I once accidentally hooked up to the hi side during charging , luckily the canister didn't blow up but got me to thinking , maybe we should do it from the hi side with the canister upside down so we assure that we get a proper mix off oil and refrigerant . Although , I would think preferable with the engine off and with the ac system under a vacuum , if charging from the hi-side , or maybe the refrigerant cans are under enough hi-pressure to charge on their own to charge from the hi-side with engine off ? Although doing it that way you probably wouldn't be able to just top off an already charged system .

In commercial air conditioning manufacturing, I have never seen anyone fill a system by weight. It is always done by pressure.

Also if there is a leak, get a can of that stop leak that’s right next to the refrigerantOn the shelf

That stop leak can bring havoc on a honda A/C system😢. Better to just try and find the leak with dye to avoid having to replace even more components (adding insult to injury).

[@auto-tech3101]

going by pressure on some modern systems will not work as they use variable compressor it would be like trying to charge a inverter minisplit just by pressure. As for conventional system one generally can not do superheat and sub cooling so pressure measurement would not be as accurate as weight despensing.

They have replaced its compressor and even its clutch, as well as who knows how many other parts. The stupid thing will stop cooling during a trip and then start again... repeat. Also, it makes a squealing noise only when the A/C is turned on. I told my brother to take it elsewhere because the dealer clearly doesn't hire mechanics, but simply parts changers. 😆 Also, thanks for mentioning that Auto Zone loans vacuum pumps. It's good to know that I don't have to buy one and I'll be able to work on my '02 Saturn's A/C system, which has never failed, oddly enough and I live in Texas. 🥵

You are my fave car guy!! And it's not because you and Dennis Hopper are doppelgangers! 😆 I've saved so much $ doing little fixes on car with help from you and KZbin. Thank you.❤

Hello anthemgirl4880 what kind of car you drive just wad curious I can't afford a mechanic since last year I've crossed paths with his channel since I have no knowledge of vehicles? By the way he sounds like Joe Pesci a little huh🤔

If your just adding refrigerant then having a full gauge set makes it much easier since you can use the temperature/pressure differential chart to determine when the low and high side pressures are in balance for the current weather conditions. On and old system its good to get at least one can of refrigerant with an oil and dye charge in it to accommodate for any oil loss from the multiple rubber hoses and seals using the can with the oil/dye first. After the first time I used the full gauge set I've never gone back to just using a low side only gauge and guessing about system balance. Plus by using the pressure chart with the gauge set you can also quickly tell by the readings if you have a bad expansion valve or compressor. Some have been pleasantly surprised when they thought that because the DIY low pressure only gauge showed they had the right amount of refrigerant and weren't cooling well they needed a new compressor and expansion valve (which a Specialty Pro AC Shop had verified along with was very willing to charge them well over $1,000 to replace them) that while reading the gauges with me along with reviewing the pressure chart showed it only needed a little more refrigerant to get the system balanced and cooling efficiently again. A partial can of 134a later got them a balanced system that cooled better than it ever had since they bought that Toyota and it didn't cost them over $1,000 to get there. Over a year later they still tell me its still almost too cold despite our semi-tropical climate with effective temperatures hitting well over 110 degrees the past few days. They are so glad we chatted and checked things out with the full gauge set before they gave up and traded the car in for something newer since they couldn't justify the cost of installing the new parts the AC Specialty Shop had told them they absolutely needed. Best!

Outside temps make the AC temps inside much cooler lol

[@neilfromclearwaterfl81]

@@Jesse-rj2ye However even in that case a Hi/Low pressure full gauge set along with a temperature/pressure chart will let you see whether your charge is in balance for that particular ambient temperature and take the guess work out of it. AC units can blow really cold when its cold out so a little understanding of the physics behind the process along with a decent gauge set will allow you to get the job done right even in cooler weather. Best!

2012 CR-V just went in the shop for low cool. First time. Low refrigerant. Going back in 10 to 15 days to look for leaks (dye also added). Nice to know they all leak a little.

Hey Scotty, I really enjoy your video's, without fail, I learn something new every time, not only that but you also speak in plain English not technogobbledeegook, my one regret is you don't live over here by me in the UK It would be great to have such a knowledgeable and trustworthy guy to keep me on the road, keep making your excellent video's Scotty and I'll keep on ringing that bell.

[@breakerone9119]

Yup your right about removing all refrigerant. Non condensable's can play hell with you during the diagnosis. Always scale in your charge and pull a vacuum to the appropriate micron level to confirm you have no leaks and any moisture is gone. If you hold a micron level for a half hour or so you are guaranteed there will be no leaks and you can charge the system and confirm it works and your good to go. If you don't have a way to know the charge on a vehicle you can always get a P/T chart and do the old rule of thumb on your discharge numbers. Ambient plus 30 degrees converted to pressure should get you close for a discharge reading as long as the condenser is clean and fans are working. To everyone out there good luck and keep up the videos Scotty!!!!!!

[@GUYANESEGT]

when you vacuum it out, where does it go? is it in the vacuum system? does it release it into the environment? How do you dispose of the refrigerant that you took out?

[@shawnsatterlee6035]

It goes to atmosphere obviously! N so what?

[@gunkyzip]

-7:09 I was waiting to see if Scotty would purge the refrigerant line. 👍🏻 If you don’t have a bleeder valve like his gauges you can simply loosen the yellow line at the gauges to bleed out the air.

I don't even need to do this (thankfully, because we're in prime heatwave season!) but I watched the entire video because Scotty is so funny and informative. Now I'll go find a video of his I actually need.

Back in the 80s, 90s,as a line tech, we would compete against each other, installing factory a/c systems, in new cars, from dash switches, to compressor, and mounting plate, condenser, evap, wiring, etc. We could usually have cold air blowing in a couple hrs.

Thought about installing one of those windshield washer kits and putting the sprayers in front of the condenser. Often sitting in traffic and the ac doesn't work as good, noticed if there is water on the condenser it works a lot better all around! Also bought a set of gauges a few years back, family and friends are coming to me every year to check their ac when its not working right xD (got a nice used vacuum pump for $20 too! Things been solid for almost 5 years now!)
