i it legal fr people without refrigerant licence to own r34a? im pretty sure it isnt, and dude dont let anyone catch you bleeding the hose like that because that lets refrigerant into the atmosphere and thats a $10,000 fine.

[scottykilmer]

@justins462 depends where you are. Here in Texas, anyone can buy 134a at an auto parts store. And that tiny bleeding isn't going to do much. But if you are in a more restrictive area, pay a mechanic with recycling equipment.

Hey Scotty, my car's AC system is completely outta refrigerant and has been for probably 8 years or so now. If I were to suddenly go fill it up, would it cause any problems with the lines or other parts after not having pressure for years? We took it in a few years back but re mechanic didn't fill it because he thought there was an electrical problem. Is it safe to fill up/recharge the system still?

[scottykilmer]

@BowlingMania14 generally they are toast sitting that long, moisture gets in the system and ruins Everything inside. But if you want to gamble, put 3 ounces of pag oil in the system first, and then do as in this video and PRAY.

how do i put air in my tires??

[scottykilmer]

@farerse you get an air pump and pump it in. Most guys buy a cheap one these days for 10 bucks that plugs into the cigarette lighter.

@scottykilmer Heh Heh Nice job of checking for leaks, but I realise this is simply a guide and most people would go to a A/C Mechanic anyway.

Laws regarding A/C differ as you said and here in Australia it's the same What I used to be able to do I now cannot because it would cost me too much to get certified to do A/C even though I have worked in the trade like you for many years as a Mechanic

@scottykilmer thanks! and good videos

[scottykilmer]

@cyborghunny yep, same way, just different pressures and gases.

[scottykilmer]

@danger86rangerr AH, but unfortunately it's the ONLY way to do it correctly, guessing with levels and not evacuating a system is pot luck repairing. and the stuff doesn't cost that much at places like Harbor Freight tools.
