Have noticed that my 2010 Corolla A/C is not as cold as it should be. Went to YT and found a video that Scotty made on May 27, 2019 recommending NOT to purchase A/C recharge kits. Believe he said that you need to monitor the high and low side and the product could damage your system plus the built in gauge was probably not all that reliable.
His video in the last day or so (Toyota that went 80K without an oil change) Scotty mentioned buying an A/C recharge kit while in NH to help his son.
I don't see every video Scotty makes and it's possible I missed something along the way. Products do evolve and perhaps this product has changed?
Appreciate any clarification Scotty. Thanks for all you do. I have learned a great deal watching you.

Well, my take on Scotty using one of those recharge cans to work on his son's vehicle is basically that he knows what he is doing and has decades of experience enabling him to carefully judge what is going on to an extent even without all the usual tools used for AC service. Also if something is damaged using one of those cans he would be able to just go out and buy some tools and parts and repair it himself.
The average car owner who doesn't really know anything about how AC works or how to work on it is in a different position. He or she will typically look at one of those cans as a magical fix where you just hook it up and "fill to the green" to make things work. A risky proposition without the experience to understand what's happening inside the AC system or what to do if things go horribly wrong.
I personally would not use one of those recharge cans. You can get a inexpensive manifold gauge set and pure R134a (without sealers) in small cans and be able to purge air from the charge line and monitor system pressures. There are plenty of youtube videos showing how to do that.
One thing that needs to be emphasized is to always wear eye protection when working with refrigerant. You do not want that stuff getting into your eyes.
Thanks for the kind words but bear in mind I'm not a pro by any stretch of the imagination. However I did learn from a friend who was a master automotive AC technician with decades of experience, sadly passed away several years ago. I would consider myself lucky to have absorbed a few percent of his knowledge and experience.
Well I wish I knew a fraction of what you know. It's the kind of thing where I take it to the AC shop down the road and happily part with my $100 to have it recharged. They also give you a coupon for the ice cream shop next door.
That sounds like a pretty good deal, if I had a shop down the road like that I might not even bother doing it myself. Mmmm, ice cream!
