Its best to evacuate the a/c but if you are careful you may be able to hook up your freon tank and lightly charge the system if it works cold just let it be and if when it is real hot it feels warm instead of cold you might add just a little more freon but be careful.
Go to autozone or similar and get a can of freon with a guage. Hook guage up set arrow to outside temp turn a/c on full and add freon to the right red mark.
There are special cans of R-134A with dye in them for detecting leaks. Most leaks occur around the fittings near the compressor. Recharge the system with the leak detector can or R-134A. There are also cans of R-134A with an additive to stop leaks. I would use these products to either detect your leak or to stop it. Best of luck.

Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.

check pressure it may have leaked out already, also pressure test will tell if compressor is bad or other leaks, u can put dye in system and look for leaks yourself availible in most part stores, look at front of vehicle and look at condesor and see if any obvious damage

cold air on passenger side of car and warm on drivers, why

Could be a blockage. Get an air-con specialist to blow the lines out. Check for any leaks from the rubber pipes. The twisting nature of AC pipes in cars can perish and if you have heard a blow out (like a tire blowout) the air con might have blown through a pipe.
Any leaves trapped in the windshield/hood gutter?
