Why does my evaporator need to be replaced?
Why does my evaporator need to be replaced?
The main reason that an evaporator coil would fail and need to be replaced is due to erosion. Over time, the refrigerant flowing through the evaporator’s coils wears down the inner lining, making the coils weaker. Certain evaporator coil cleaners can also corrode and weaken the outer lining of the coils.

How does the expansion valve in an AC evaporator work?
The expansion valve plays a very important role, as it reduces the pressure of the refrigerant. During this process the liquid is cooled, which allows it to absorb the heat and thus cool the air. The blower fan draws hot air from your house over the evaporator coil. As the air passes over, the refrigerant within the copper tubing absorbs the heat.
