Hey, I heard you can simply refill the coolant and your ac is good as new... It is just blowing out cool air when set to ac, as opposed to freezing. Where is the coolant stored and how can I get to it?

I'm wondering if it's NOT the AC but the blower fan, how does the heat side blow? if it's good on all blower settings then, it's more than likely your blender door is not opening and closing all the way. When the blender door stays open a little bit it'll let warmer outside air mix with the cold AC air causing it not to be as cold as it should.
Are you saying the air coming out of the vents is not cold unless you are moving ? Or there is no air unless you are moving ? And are you sure the radiator fan is running with the ac on ? Can you feel air being pulled thru the condenser ? What are the gauge readings with the ac on and the engine at idle ?
if the fan is running inside and the environmental controll is set to cool the AC compressor under the hood
a click is heard and the compressor should start, it should cylcle on and off periodicly , if this dos not happen
Have your AC system checked.
If your AC cools the air at all, then it is probably not a serious problem ... you most likely need to have your AC system recharged. You can take it in to a mechanic to have it refilled (shouldn't be expensive or take a long time) or you can go to an auto parts store and do it yourself. When you are at the store, make sure you are getting the correct type of AC coolant (a lot of times it is still Freon ... but some auto-makers stopped using freon in the 90's ... the clerk at the auto-parts store should be able to tell you what type you need). If you are unsure how to fill the AC coolant, the clerks at the auto-parts store might be able to help, but if they can't grab a Haynes manual -- it has step-by-step directions and pictures to help you get the job done right.
Most probably just needs to have the AC serviced and refilled with coolant. Since the car is a '95. I had to bring in my to get the coolant refilled just a few weeks back and it is a 2004. We used to just call it a freon refill, but they don't use normal freon anymore, they use a coolant/refrigerant that is safer for the environment, but this doesn't matter for you. Just bring it in to your mechanic or to your dealer and have the AC serviced.
They should probably put in a dye as well to see if there is a coolant leak, If so, it is usually a very slow leak and repairing the whole AC unit wouldn't be worth it. Either way, it needs a fill.
the reason it's getting warmer is most likely due to a slow leak. it need the proper amount to be cool. less or more and it will be warm. it's also possible when it was charged he added too much or not enough. also if air is in the system (from not vacuuming the system or in the refrigerant tank) it will not cool as well.
the car need to be recovered, vacuumed (checked for leaks), refilled after purging the refrigerant tank of air.
I know from experience that if the coolant is to low ( not just the freon levels in the compresor but the antifreeze/coolant level as well) the AC system will not cool and will blow hot. Check the coolant Antifreeze and freon levels, even with the Coolant being a little low my 1998 Ford E150 Van will blow hot. After you have ruled out of these possibilities and the chance it is the thermostat most likely the problem is what Ford calls the "Flap" it controls the air flow through the vent system when you switch from Heat to AC. When the Flap is working it closes off one systems air flow so as to not interfere with the current climate selection.
