Air Conditioning. I have a ruud system with the air conditioner outside and the air handler

Question

I have a ruud system with the air conditioner outside and the air handler upstairs in the attic. My systems appears to be running, and I can feel cold air at the vents, but I can barely feel it. Like there is no flow. The fan outside is running and the unit in the attic is running. I have no clue what the problem is. The large coil coming from the heat pump outside is cold and has condensation on it. It also seems to have a little ice. It has been extremely hot here in Georgia the past few days 100+ with the heat index. What can I do to fix this problem? I just changed the air filters and I am not sure what else to do???
