Yesterday, after I changed the extremely dirty air filter, I turned off the AC and just ran the fan for 4 hours and I thought I had everything melted. When I turned the AC back on, It seemed to work for a while but this morning I saw it had frozen up again and the air was not cold that was comimng out my vents. The furnace/AC is only about 3 years old.

Your coil will freeze up when you are low on freon. I'd call a repairman. That is not something you can fix youself.

The filter protects the coil inside the unit that makes the cold air. Chances are if the filter was extremely dirty, the indoor coil is going to be dirty.
Try getting a mild detergent and cleaning the indoor coil. Sometimes these are difficult to get to and may require a pro.
If you clean it and it still freezes up, you probably have a leak in the refrigerant system and will need to get that repaired by a pro as well.

The evaporator coil itself may be dirty. Open the cabinet and take a look. Most hardware stores or home centers should have coil cleaner to clean the coils. A stiff paint brush will also work to brush off the coils. While you are at it, also clean the outdoor coils.
Run the fan to thaw out the coils prior to cleaning. If the system freezes up after cleaning, you will need to call a pro to look at the system. It could be low on refrigerant, and they will need to locate and repair the leak prior to charging.
70% of the time it is just a clogged evaporator coil.
