You don't...ask a local A/C shop to check your system...often $29-39 and they add/R314 and diagnose it for free.
Good Luck

    This dude must work in a shop and wants you to come in to charge you $$ just to look. DO IT YOURSELF.

Where do I add freon in a 2003 buick century?

This job requires special tools and training, it is VERY easy to get hurt badly. It is illegal to not recover any refrigerant in many parts of the world. I suggest that this job be performed at a qualified shop.
Refrigerant goes in the low pressure port.

I want to add refrigerant to my 2005 Buick Century... 6 cylinder. How many cans; it says to charge using the low side. How do you determine the low side

It depends on the size of the cans!

The low side is the "thick" pipe that comes straight out of the inside radiator (evaporator) to the compressor, the high side is the thin pipe, running from the compressor to the outside radiator (condensor), then the liquid receiver (the part that looks like a soda can) Add a can of freon while the car is running with a/c on, check the sight glass on the liquid receiver the whole time. If there is enough freon in the system the sight glass should look almost full. If it's not enough, add another can.

Sounds like there is a refrigerant ( freon ) leak somewhere in the system. The A/C system will have to be partially refilled, and then leak tested. Only then will an accurate cost of repairs able to be determined. Hope this helps.
