my AC unit was frozen up Saturday so I went outside, and cleared all the debris (leaves, pine straw etc) from around the base of the unit, and off the top of the unit and left the unit off for about 12 hours to "thaw"
I have now cut the unit back on, and it has been running for 6 hours, no freezing up, but the set-point (of 73) is never being hit. When I use the "gun" to check the temp of the air being blown from the vents it reads at a 75, and the thermostat reads an internal temp of 78 (usually as low as it will get during the day for about the past week).
Does this sound like a low on coolant type issue or something else? Something I can repair on my own, or do I need to call out a professional to diagnoze/repair?

Call a service technician. Your system probably has a leak, and is low on refrigerant.
The system iced up due to low refrigerant. Then as more refrigerant escaped, the system lost the ability to cool.
