AC blows Hot. Refrigerant Level OK

Lack of cold air would typically mean low refrigerant, but actual HOT air more likely means a stuck blend door open to the heater core. The heater core is always hot, only the blend door prevents air from the blower moving across it, by redirecting the air to blow across the AC evap coil instead. The number one cause for a stuck or malfunctioning blend door is the actuator that controls it. Move your dash control from hot to cold, you should be able to hear a door moving inside the dash, or at least a change in pitch in the air flow from it. To repair, you'll have to gain access to the dash where the blend door is, look for a youtube vid on repairing temperature blend doors for your make and model.
