Welcome to AF.
We need more info to help you.
What engine?
Auto or manual ac controls?
Any check engine or ac panel lights on?
Does the compresser run when air turned on?
On the freon that you put in it?
How much and what kind?
How did you add it?
Was the compresser running or pulling it in when you added?
We need low and high side pressure gauge readings at idel and at 2K rpm?
What is your system pressure?
Post back pressurre readings and we can help.
A warning on .

You cannot properly and safely recharge an air condition system with them.
The one side stop and go gauge does not tell you what your system is doing or is over charged or undercharged.
A overcharged or malfunction air condition system can reach over 500 lbs of pressure.
Enough to blow up that can or system and freeze you at first and the burn you or blind you and if any propane /butane in there blow and light you up.
The stop leak crap and who knows what kind of oil in the kits there will stop your system for sure.
Just like pouring super glue in it.
And some kits even contain freon with a butane mixer.
Good for a big blast.
If you are going to do it do it right and safe.
Here is what you need to start with.

In the older days you could just throw in a can and go.
But over the years just adding freon is getting harder to do.
Newer systems have to have the correct amount of freon down to the ounces.
Most will need pumped down and vacuumed down and the right and amount of oil and a set amount freon charge installed to get the air to cool right and the system to last.
If an air condition is low there is usually a leak that needs fixed and also a lose of lubricating oil from system.
Also air and moisture enters a low system
If you are going to try to do it get the proper type air condition gauge set with the low and high side gauges.
Hook up the gauges and get a reading with compressor running at idle and at 2000 rpm on the high and low side.
