A common cause of a car's AC not working is a loss of refrigerant, generally caused by a leak. A mechanic should drain the system, find and fix the leaks until the system can hold pressure, then refill the system with a proper amount of refrigerant. However, this system can be used to pump refrigerant into the system until a certain pressure is reached. The problems are: (a) there may still be a leak; (b) the refrigerant is supposed to be measured by mass, but these self-service tools can only measure by pressure so it might be off; (c) many bottled refrigerants contain sealants that may cause trouble down the line; (d) the system needs oil, which is not being supplied; and (e) the system may now contain moisture.
If you have a car 1994 or newer and the air conditioning doesn't blow cold this kit will allow you to add Freon so the air conditioner works for a while.

Of course if your car is low on Freon that likely means you have a leak. To fix that you would need to take apart all the hose connections and replace the o-rings, then use a vacuum pump to evacuate the system and then add Freon. Of course the cost for all the equipment to do all that is roughly the same as taking the car to a mechanic and saying fix my air conditioner.
Unless you system has a total / almost total loss of pressure you'll be fine, slow leak, perhaps taking years between 'charges.' If you have a bad leak, recharging will not likely help for days if at all.

That is why god created pressure-temperature charts (that can be found online and normally come with these kits)

That has not been the case for decades. The sealants no longer not 'gum up' internals like in the days of ol. They only react to the presence of moisture* and sometimes cause o-rings / gaskets to swell (making a tighter seal).)

Unless you had a complete blow out, oil is still in the system. Also many of these kits do supply some oil. Also they tend to contain *moisture neutralizers for inside the refrigerant loop (and preventing sealants from reacting where they shouldn't). There are many recharge kits: with oil, without oil, with sealants, without sealants, with UV dye, without dye, moisture neutralizers, no moisture neutralizers, or pure refrigerant if you don't like additives.

But you are right, in a perfect world you'd drop your car off at a mechanic then pickup your revitalized AC a day later. But that $1000 difference in price is where the problem is. $30 does have a few downsides over actually doing a true "repair" but if it fails, you'll be a square one either way.

I did the ASE A/C certification course years ago and while I thoroughly understand the "right" way to fix an A/C, I totally see the utility of adding a bit of refrigerant with one of these cheap gauges to an aging, not broken, system. If your vehicle's air has slowly been getting worse over the years, a quick top off will likely do the job. If it all of a sudden up and quit, then take it to a professional.

And I call it freon. People often think of the thing in their kitchen when you say refrigerant and glaze over when you say R134A, while most understand what is meant by freon, even if the particular refrigerant being used technically isn't.

Quote from Banana_Fly :
99% of the time your R134 has slowly leaked out due to industry standard expected 1/4 oz/year leak per each fitting. There is nothing to fix. I'm not suggesting this tool as a replacement to a proper manifold gauges, but it is day and night better than no tool at all or better (or not) than a crappy gauge on the R134 bottle from Walmart.
People who use this device do not have $200+ to go to service and do full evacuation which is actually not needed if you are just adding 2-3 oz of R134a
Just from my personal experience, these don't work. Just my 2c ...

Maybe you have had better luck.

Quote from Clk1986 :
From what I heard from various sources when troubleshooting my cars AC, leaks in automotive AC are expected, whereas home AC its not. So some refrigerant loss shouldn't be concerning if its over the course of 5 years or so. When you're recharging it once a year or more frequent, then I'd say have the leak found.
Home systems they pull a vacuum and leave it sit there for a couple of hours and make sure that the gauge doesn't move to check for leaks. If whoever does your AC install doesn't do this, make sure you fire them and get another AC installer.

The main problem with the avg user adding a can of Refrigerant to fix their AC is that if you don't have basic troubleshooting techniques, you aren't likely to get results.

Most people don't understand that the compressor needs to be operational for these to work. If your system pressure is low (empty/clogged)!or too high (overfilled or moisture/air in the system, or clogged), the compressor likely won't run, because of AC Hi/Lo pressure switch.

If you're too Low, you'll have to jump the relay connections to see if the clutch engages. If it does, you might be good. The best thing to do would be a full service shop, where they don't need the compressor running to add refrigerant, but if you are dead set on saving some cash, you'd need to follow the instructions on the can and then jump that relay, with the car running, and add refrigerant. A good 5-10 seconds of refrigerant might be enough that you can remove the jumper and throw the relay back in, and your compressor will work as it should (due to Hi/Lo pressure switch showing appropriate parameters).

But like I said, the amount of people not able to figure this out and release refrigerant into the atmosphere (r134a contributes to greenhouse gasses) is likely the majority of the DIY'ers. And, here in WA, part of the reason why we cannot buy the r134a refill kits.

And, just a disclaimer, I'm not saying the way I suggested (testing compressor with car running) is a good idea. Car is a 2004 Civic Si and AC hasn't worked since I bought it in 2015. Figured it was worth a shot and it worked for me. 0psi . Now, I will say, I probably want to get the system properly flushed and refilled now that I know it works, though I'll probably give it a month or two, so I can see if there is any significant pressure loss.

So the AC in a 10 year old car is supposed to be just as cold as a new car- provided everything is working properly?
There's never any leaking?

Yeah, that's the thing I still don't get after doing some research. The refrigerant should last the life of the car with everything still working (no leaks, compressor kicks in, etc)?

Well there's usually some bit of leaking but it's usually such a small amount that you can recharge your system with a couple oz of refrigerant and it will hold for another ten years...or you could get lucky i guess and have absolutely no leaks and no need to recharge after ten years but that is probably highly unlikely...and yes it would get as cold as a new AC would get....air conditioning technology works on basically all the same principles....refrigerant changes over time to be better (or less bad) for the environment but it gets you cold just the same.

Just because you have a leak doesn't mean your system is broken, it is normal to have tiny leaks that you don't really need to address, at least until they become bigger leaks if they do, i.e. needing to recharge your system more than once per year or even two or three years...then you may want to look into it but still a judgment call.

In most cases you don't need to go to your local shop and get ripped off. Just youtube it, it's not rocket science.

Well, mine has been 16 years, AC isn't blowing as cold as it was before.

Well I interpreted the question as, if all the components are functioning 100% on an old car except there is some refrigerant leakage...will it blow as cold....and I would say yes. But, if there is wear on the components, like the compressor clutch not engaging anymore, sometimes you can jerry rig a fix or you can buy a new one and should be good as new. Anyway I didn't read the whole thread I was just chiming in on that one isolated post.

I just want something simple to give a little top off because I'm sure there's some leaking over many years. I'm thinking this maybe the way to do it with some small containers of a134 from Harbor Freight?

I purchased this hose from Walmart last month for about 15.00, I returned it 2 days later after I used it. I have no use for it after 1 time.
If I need it again, I'll do the same next season or finally get the leak repaired.
The freon was about 12$, they were about $4 maybe 2 years ago.
