What an AC evaporator does?

After the expansion valve or orifice tube ,inside the evaporator, the pressure of the refrigerant is allowed to decrease from the high pressure of the liquid refrigerant to a very low pressure. This pressure change inside the evaporator causes the refrigerant to boil, or evaporate. The latent heat of absorption from this state change makes the evaporator cold and allows it to pick up excess heat from the outside air or re-circulated air before it reaches the passenger compartment.

What are the main causes of an evaporator core failure?

-Refrigerant Leakage
-This often happens because leaves or other organic material enter the evaporator case through the exterior air intake vents and come in contact with the evaporator’s surface this moisture surface and decomposition of organic materials, can form corrosive substances which could eventually damage the evaporator core.
