Answer: Sweating of the air handler is a very common problem in the southern states of the US. This is on account high humidity level is these regions. However, in this context you should know that moisture in the air is only a contributor in sweating. The phenomenon is mainly caused due to interaction between the hot air with cool metal surface. The hot and humid room air comes to evaporator coils which contain cool refrigerant. The refrigerant absorbs the heat of the air and makes it cold. But as the hot air comes into contact with cool metal surface of the coils that contain the refrigerant, condensation happens.
