My air conditioner is not blowing cold air. After it runs for a while it will blow coolish air but never cold. I put in refrigerant and it worked for a day. It won't take more refrigerant.

A/C systems are very complex and take special training and equipment to properly diagnose and repair. If you added refrigerant and it didn't fix it, then you should take it to a repair shop and have them look at it.
