There's no such thing. As the first source says, "The problem is that you can never tell how much refrigerant is in the system before you start to top it off. You test and diagnose A/C system using manifold gauges. They provide a pressure reading. That pressure reading is in no way related to the amount (weight) of refrigerant in the system. Therefore, you can never be sure of how much is already in the system."

You can only make it worse. If it needs service a professional can do it for about $100 (prices vary a lot - call around) If you or I try it we will either undercharge or overcharge it enough to seriously shorten the compressor life. I would venture over half the compressor replacements are the result of people trying to charge it themselves and starving the compressor for oil by undercharging or "slugging" the compressor from overcharging.

First things first, normally I'm not much a sticker for grammar. But what you posted isn't a question. Putting a question mark at the end of statement doesn't magically make it question.

Moving on…

If you look at the symptoms you can generally make an educated guess about what the problem is. For example if the air from the vents takes longer to cool down and doesn't get as cool as it should, and the compressor is cycling on and off quickly, then that's a good indicator that you're low on refrigerant.

It must be said that a car's A/C system should a be completely sealed, it should not lose refrigerant. If you're finding yourself adding r134a, then you have a leak. If you have a small leak like my car had up until recently. Then yeah, it makes sense to add a can or two of refrigerant to get you through the summer, it's a cost effective short-term solution. But it will not fix the leak and the leak will worsen with time, and you'll eventually have to get a proper repair. The leak will eventually get to the point where the refrigerant leaks out quickly, and at that point you're just wasting money by adding more refrigerant. But it can take years to get to that point.

I do have a set of HVAC guages, but most of the time all you'll need is an over the counter AC/Pro charging hose/gauge and a can of R134a. (This is assuming the symptoms of your problem match what I mentioned earlier). What you'll do is have the car running with A/C on Max cooling, fan speed on high, recirculation on, etc. Next you find the low pressure port for the HVAC system (DO NOT USE THE HIGH PRESSURE PORT, IF YOU DON'T KNOW WHICH IS WHICH, THEN DO NOT ATTEMPT THIS). You'll attach charging hose/gauge to the port using the quick connect/disconnect coupler end. Once you do this, note the pressure reading on the gauge, it it's reading in the green zone or the red zone, then you have problem and the car needs to go to a shop. If the gauge is reading below the green zone, then it's going to need some refrigerant. Screw a can of r134a on the recharge hose/gauge. And pull the trigger in 10-15 second bursts. Slowly rotating the can as you do so, after ever 10-15 second burst check the gauge again. Once the gauge gets into the normal range (which will change based on ambient temperature), disconnect the hose from the low pressure port and check the temperature at the dash vents, it should be much cooler.
