Hey guys, so, before you say it, after reading I realize I should have taken it to a shop to get a re-charge. I assumed it was a simple job so I tried to do it myself, but I think I air may have gotten in the system and frozen in the lines somewhere. I will be taking it to my shop to be vacuumed and re-charged, my question is: is it safe to run it until then? Will I blow the compressor or the lines?

i have been working on, repairing, and fixing vehicles for over 25 years....and in all that time there is only one part of a vehicle i have never touched, the A/C....that is the only thing i always leave to the pros

Parts stores and the like that sell AC recharge stuff to the general population just plain suck.

It seriously devalues proper education and experience. As a professional, I have certifications and a license.
Rookies don't, and neither does Joe Schmo.

Professionals have rules to follow, and expensive equipment to purchase in order to follow all the rules of refrigerant recovery and recycling.
Joe Schmo has no such rules to follow.

Joe Schmo can go to WallyWorld (and others) and pick up cans of supposed freon (read the labels! Many are not really 1,1,1,2-Tetrafluoroethane (CH2FCF3)) and DIY attempt to ruin their own AC system and/or blow themselves up.

Real pros (I would hope all of us professionals) will check what is in a system before they connect their expensive equipment to your hacked up car. If it isn't 100% genuine R134a and/or contains sealants, your system is deemed contaminated and many can't and won't touch it. It takes even more expensive equipment to deal with contamination correctly.

So if I go to my shop I should let them know what I did so they can handle it properly? If i did indeed freeze my system, is it safe to run the a/c or am I going to blow something?

If it were me, I'd want to know ahead of time.

I'd also want to know WHY you touched it in the first place.
What underlying problems might I need to deal with after overcoming the first obvious hurdle?

If it doesn't work, don't use it until it's fixed.

I did it because it wasn't really blowing very cold. So i recharged it, it's now blowing a little warmer than before since recharging though. When I had the can attached, it was at 43ish psi but wouldn't go higher even though the can was still ice cold like it was trying to vacuum it. Yes, by the way, the car was on with the ac turned on.

When you only have one pressure gauge connected to an AC system, you are only getting half of the story.
Your can connects to the low side. You have no idea what's going on in the high side of the system.

The AC systems these days are so small, there's very little room for error. Just a couple ounces higher or lower than specification really diminishes performance.
(Spec is 500-550 grams)




That's a normal phenomenon.

What psi should it be at?

Too many variables, there is no single correct answer.

Thank you ezone. I know it can be annoying when people make mistakes like this instead of just taking it to a pro. I actually want to go into auto mechanics so I do really appreciate your input whenever I post. Normally I do research work before I do it, but this time I didn't.

Pros make plenty of mistakes too.
