No such thing as AC coolant. It is just coolant. If the car doesn't blow warm air when the coolant level is low, that is a normal condition, and also blows hot air out the vents when it is full. It all comes down to a simple leak somewhere. The cooling system is pressurized, so any leak will effect the system. Find the leak and repair. A shop can pressure test the system with a special tool to find the leak much quicker than you looking around and under the car.
