This is a confusion people often have regarding their air conditioning systems. They think that because the AC sends out air that feels like it was blown over ice, ice must be a normal product of how the system operates. This does make some sense—until you understand that an air conditioner works through a process of heat exchange, meaning that it uses refrigerant (a special blend of chemicals) to remove heat from indoors and release it outdoors. Not only does this process not use ice, but it also shouldn’t create any ice.
In other words, if you see ice on your air conditioner, something is wrong.
