Best Answer

The system will not cool if it is low on refrigerant. Check the suction line and see if it feels cold and is sweating. The suction line is the larger of the 2 and is covered in black insulation. If it is not sweating or if it is warm to the touch, you are probably low on refrigerant. If you have to have refrigerant added more than once, it's a sure bet there is a leak in the system.j3h.

What exactly is central air conditioning I know I have AC, but what makes it central?

Central air conditioning is an air conditioning system with a central unit that distributes air to the rest of the house through vents. Some people have air conditioning units that are separate for each room, but most houses today have a centralized unit, usually located outside the home, which pumps air to each part of the house through the ventilation system. That is what is referred to as Central Air conditioning, because there is just one centralized unit cooling the entire place, as opposed to many autonomous units cooling each room.
