She's right that your car doesn't have Freon per se...Freon is a type of refrigerant.
There is a port on your a/c system (usually covered by a blue or black dust cap) that you can put a gauge on. This is the low pressure side. There is also a red dust cap over the port to the high pressure side. You want to gauge and add refrigerant to the LOW PRESSURE SIDE ONLY. Messing with the high pressure side is not advised. You can buy a gauge for cheap from just about any auto parts store. Also you can buy canisters of R134a for $3.50 each. A typical automotive a/c would take 3 such canisters to fill assuming it was empty when you started. (your system is likely not completely empty, I was just stating this to give you an idea of how much 1 can really is in relation to how much is in a full system).
One thing of note though, your a/c is a closed system. If it is low on refrigerant then that is because some has escaped somehow. When the a/c is not used for long periods of time and when it gets cold outside, the seals in the a/c system can contract slightly allowing some of the refrigerant to escape.
Hope this helps!

get a recharge kit at any autoparts store. Follow the directions that come with it. This is very easy to do yourself
