You're not subtracting the weight of the can first.
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.
I recently took a class to become 609 certified. The stuff in this video is basically exactly what they taught me in that class. Nice job, Scotty!
Same here
are you kidding me? if you have a epa609 you should know this is all wrong. charging 90psi on the low side means it's about 200f outside. this guy is so wrong about so much in every video...
@@yarisftw3736correct you are
@@yarisftw3736 I agree . I especially like the fact he is not mentioning to get the system recovered just vent it with a vacuum pump, Really nice EPA fine for that advice.

Wait...where's the LYSOL Scotty???
😅 I was wondering the same
Lysol..... there's no stinking Lysol.....😮..... Scotty in Alabama 😎.......lol
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.
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.
application-designed systems use hard lines- cheaper uni-fit systems and kits utilize hoses. that means the froil is used exclusively to lubricate compressors.
Thank you for the tips.
What is the purpose of the Lysol can in the thumbnail?

Love this guy I’m almost 50 yr old woman I know nothing about cars my break master cylinder went a few years ago on my suv and I replaced it myself by watching one of those man’s videos! Took me less then 30 minutes from start to finish that’s with letting the air out of the break lines. Saved me about 500$ doing it myself!! Been driving it for a few years now no problems!! Thank you !
That is awesome! I want to change the oil on my car my self and hesitant but, you did what you did, I can for sure change the oil.
@@RachelsBadAssJamz64oil change is pretty basic. Just make sure you put the drain plug back in! lol

It starts to get cool only by the time you get where you’re going. Only gets too cold on long drives!

Did I miss the Lysol segment?
The joke is, lysol is worse for the ozone layer then r134a and we just spray it openly
Thx Scotty. The Lysol spray really came in handy. Just a few sprays in my interior and my car temperature dropped immediately by 30 degrees. You are a lifesaver. Can't wait for your next video on using canned refrigerant to disinfect my toilet.

I still have the fear of rust. I don't like how a car slowly deteriorates because of rust. Maybe it is a metaphor for life, how we are slowly getting older and eventually dies.
@@johanhallgren fluid film my dude. If that doesn't work, patch the hole with epoxy and fiberglass. If it's a part that can't be patched with epoxy and fiberglass, buy a new part.
Stop rust when it starts small. Use a wire brush, rust converter spray, and rubberized undercoat, or clear coat spray for body work. Touch it up before Fall weather sets in. Then use high temp exhaust paint on your exhaust system.
Been doing this to my 10 year old car and it still looks like new and has the original exhaust system!
@@johanhallgren Move to Las Vegas, NV. It's so dry, no rust will form on exposed metal.

Just finished my A/C ASE for my Toyota Certification and this is almost a 100% match for what I learned.
Our 2019 Odyssey came overfilled from the factory with R1234y. Symptom was short cycling on and off of the compressor. Thanks to an online forum and a TSB, the dealer completely vacuumed the system for 4 hours and then loaded with the spec amount of the 1234xyz refrigerant, much like Scotty in this video. This was 3 years ago and It has operated wonderfully ever since (now at 83k miles)
I would love to mute this video then play it on a giant screen in front of a full orchestra and listen to what happens
Lol
Scott, you da man. What I wanna know, is your energy this high all day, every day? I've watched a bunch of your vids, & you're always so wired. Wish I still had it like you do ! Great Show, Bro.

I didn't watch the video, I just sprayed Lysol into my face. I think I need to go to the hospital
I'll bet-cha... you also drive Chevy.
Interesting. Last week I received a notice from Honda about that AC compressor seal. They acknowledged a problem. They're extending my compressor warranty from 3 years to 10 years on my '17 CRV! This is how you treat customers.
You can measure and weigh the first can just to be sure can is accurate. Thanks again Scotty. You the best man.
Scotty, my Toyota dealership mechanic said you are only a CZcams celebrity and dislikes you. I told him he was dead wrong and can no longer trust him. He was dumped immediately. I trust you 100% and you are doing a fantastic job.
Your dealership mechanic is correct. I have watched several of scotty's videos and came away rather disappointed in his method's. This video would be one of them. Although the postal scale is a good one, he did not mention recovery on the system Venting a ac system to atmosphere is illegal and is close to a 40k fine.
You rock! I watch your videos and trust your instructions to the point that I search for your videos over all others. Thank you for being the person you are.
✋️love Scotty. I was a mechanic, and he is spot on every time. Thanks for all the informative videos. I enjoy watching and I learn from them.
Never knew Lysol would save my vacation!! Can’t thank you enough, Scotty!!!
Before you screw it, you have to shake the can to mix oil in it with refrigerant,
AND
for the same reason, when you screw it, you must position the can upside down to empty it.
Scotty is my online mechanic 😂
Before I do any repair or maintenance to my vehicles I watch scotty
Spray Lysol in your vents and let it pass through the interior with full AC on. Also before shutting off car, turn heater all the way to the max for a fee few seconds while disabling AC and circulate. This will prevent your car from smelling like mold and all condensation will drip out 👍🏼
Do NOT do that. Not good for you. Not good for your car.
@@sheachopper6416You are nuts...
Lysol kills mold and mildew...
It won't harm anything in the car or system...
You aren't spraying the whole can 😮
They make Lysol in many scents...
And even for your bed too...😊
P.S. Of course you have your windows open when you use Lysol...
Think what happens when you are in bumper to bumper traffic 🤔 😕 🙄 Exhaust fumes are far more deadly !!! 🎉
@@sheachopper6416 Been doing for years and my cars AC always smells fresh and clean when I use it
@@sheachopper6416nothing wrong with letting a little lysol into your ductwork. Even better pull out your cabin filter when you give it a spray. People in the dry desert climates dont have to worry so much about mildew compared to tropical moist environment types

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.
Good old R12 used to be much colder (although the blower fans weren't as powerful back in the days)

Big ups n blessings to Scotty Kilmer. Internationally known and appreciated
so shocked to find no Lysol in the video
1:46 oh cool you saved me 10 min. Well here is a Lysol brand trick. It kills fleas and their eggs. Hand to bible I use to own a rent house. The nightmares.
😂😂😂
Scotty is right! Empty your a/c system completely out first (via vacuum etc) then refill it from zero so you know its not air in the system etc ..my a/c is vlowing so cold i need a hoodie in the sunmer in my car now lol
Either vacuum it into a big tank or don’t let anyone see you venting it into the open air. It’s something like a $10k fee/reward for turning someone in to the EPA for venting refrigerant.
What kind of car and what city are you in?
What sort of vacuum pump do you need?
No, he is not right. R-134a has 0 Ozone deplation potential. However it does have a very high 1300 global warming potential, so it's illegal (at least on civilized parts of the world) to let it out into the atmosphere ! 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). And there is no way it would ever get captured by plants (CO2 does). (An F-gas Cat.II certified engineer from EU.)
@@usaman7358lmao, yes, tell everyone where you did this so you can be investigated. XD
Scotty, I hate the through-away cans like at Auto-Zone back in the days of R12 I learned Rifidgaration did walk-in boxes fridges vending machines, etc. It's been 45-50 years since I have had to do a car went to use my old gauges and said why don't they fit. It's all about the money. Keep putting them out, brother love the comedy and the info.
i did this last year i love your content keep it up !
Scotty don't ever stop!
You're crack'in me up Scotty ... You make it look so easy !!!
Complete and detailed instruction even though some would suggest it's remedial, it is correct and comprehensive. Thanks Scotty!
I love this guy, he is good at telling it like it is.
After 15 years get a new compressor. It’s expensive but its worth it. I just went through this with a 14 year old Saab and it was worth every penny. I tried this technique and that wasn’t the problem. It was mechanical. All the gaskets and plastic had worn down with 14 years of heat
autozone has a lifetime warranty on their compressors as long as you change all the components out when you replace the compressor.
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 😂
I have a 2015 Camry with 134000 miles on it. I bought it with 29000 miles on. The miles since it bought it are all highway miles. I'm thinking I should have the transmission fluid changed. You are the only one I trust with your opinion. You videos are GREAT!! Always to the point 👍👍
I will believe him over any other car tech. He knows what he is talking about. THANKS !!!!
A true testament to the Grand Marquis. My AC didn't need its first repair until it was almost 28 years old. The repair cost me less than $300 too, just needed a new drier (w/new freon) and a toggle switch for the condenser fan (your idea Scotty). Boom, ice cold air.
I had a 1970 Mercury Marquis, the body fell apart the motor NEVER leaked oil or the transmission. Always ran This 3 ton car If driven slow, 20 mpg highway
I lucked out also - asked mechanic to tell me why my AC didn't work in my 98 Explorer. Turns out it just needed a recharge! $175 including freon & pag oil.
Idk. Maybe ford does great ac stuff! My 2003 mustang has always blown ice cold and I have never needed to do anything to it. And I live in the Southeast US where you’re absolutely using it on near full blast from may thru late September!
Yeah because that's always a good idea! There is a high pressure switch for a reason which actually turn the fan on!
Can you explain what the toggle switch does please and point me to Scotty's video on that? Thank you!

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. Cheer's!
This is the first time I've watched one of your videos... Very informative, interesting and funny at the same time. I just fixed my car's AC by watching CZcams. I didn't have all the right tools but I Macgyvered it. Nice channel and glad I found it, did anyone ever tell you you look like an old Marty McFly from back to the Future?
I had an old 1989 Ford Escort LX that would blow out frost...best AC in a car I ever had.
A real down-to-Earth brainiac. Master mechanic extraordinary.
Thanks for the info Scotty. Thought I would need a new compressor. Go with the recharge first, see how it goes.
The only issue I have with Lysol is that it leaves an oily residue that may with time accumulate dirt. Go ahead and spray some on a non porous surface and see for yourself
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.
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 .
Unfortunately, many are also now mixed with stop-leak...
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.
One thing he didn't mention. What do you do with the existing refrigerant in the line before pulling a vacuum? Do you just blow the charge into the atmosphere or do you have a recovery tank?
Very funny and smart man, I love your spirit!
I talk like Scotty when nature calls but I have to deliver an important message right before. I love this channel
Thank you Scotty, you are truly a pro
What about the Lysol can??
What was with the Lysol can?
Yes Scotty is the best,thank you Scotty
Anything automotive I always check scotty kilmers advice. He knows so much more than your average garage mechanic.
It seems like R-134a still the better refrigerant. Thanks for the video Scotty!
R12 was even better ice ice cold !
...And what does the Lysol spray do?
You get better gas mileage.
Helps the algorithm. Look at all those comments!
Scotty is naturally a lateral thinking master. Most people probably don't realize it, but that's what attracts so many of us to his videos and why we all enjoy his commentary so much. Anyone reading this, Google lateral thinking and start practicing it in your life. You'll never regret it
The Lysol worked great! Thanks Scotty!
Scott, I pumped my compressor with Lysol like the thumbnail but it didn't work!
Turn the can upside down.
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.
Love ur videos, Scotty. Thanks

As always Scotty thank you you taught me something else today!!!
...wait until he paints the roof on that SHED 🐕
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
@@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!
Love watching and so informative!
As always, an informative presentation. Thank you for providing a good basic education. C ya next time.😊
Everyone loves your hard work Scotty keep up the good work 😊
Lysol in your AC lines will shock the entire AC industry.

I love the denim!! See, I'm not the only one wearing my old Denim jackets. Thanks, Scotty!
I added Lysol to my my AC system. Now it's blown up. Thanks a lot Scotty!
The reason they likely don't sell it is because people who are not certified techs (or some that are corrupt we'll say) may just open the line and let it into the atmosphere instead of properly recycling it.

Hey Scott be sure to inform viewers to spray condenser coil clean. That will or should lower head pressure which should in turn lower suction pressure. Lower pressure lower temperature 😊
Never thought of that for my car but where I work we deal with high head pressure alarms and dirty coils pretty regularly! Gotta check that out on my Subie
What coil are you referring to James Sanderson?
I love your enthusiasm.
