The evaporator in your air conditioning unit may be freezing up due to a lack of proper airflow, low refrigerant levels, or a dirty air filter. These issues can cause the evaporator coils to become too cold and freeze. Regular maintenance and cleaning can help prevent this problem.

to evaporate the refrigerant
Water dripping from the evaporator coil in your air conditioning unit is a normal occurrence. This happens because the coil cools the air and removes moisture from it, causing condensation to form. The water then drips into a drain pan and is drained away from the unit.

To prevent ice buildup on the evaporator coil of your air conditioning unit, you can regularly clean or replace the air filter, ensure proper airflow by keeping vents unobstructed, and schedule annual maintenance checks with a professional technician.
Low Ambient Temperature.The mechanical refrigeration system used in air conditioning equipment is design to work when the outdoor temperature is above 65°F. If the AC runs when the temperature is too low will cause the evaporator coil to drop in temperature and freeze over. BigBOB
In an Air conditioning unit, the evaporator is what is used to cool the air before it is blown out into the surrounding environment. It uses liquid refrigerant which is at a much lower pressure then the surrounding air and sucks the heat out of the air, thereby cooling it ready to be blown out.

An indoor unit is not called an evaporator because the term "evaporator" specifically refers to a component within the air conditioning system that is responsible for absorbing heat from the indoor air and converting liquid refrigerant into a gas state. While the indoor unit may contain the evaporator coil, it encompasses other components like the blower fan and air filter that work together to distribute conditioned air throughout the space.
$400 to $900 depending on the evap size, location and access to the unit for the serviceman. A crawl space is not cheap or fun.
The evaporator in an air conditioning unit is a critical component that absorbs heat from the indoor air. It contains refrigerant that evaporates at low pressure, causing it to absorb heat as it changes from a liquid to a gas. This process cools the air that is then circulated back into the living space. The evaporator works in conjunction with the condenser, which releases the absorbed heat outside.
To replace the evaporator coil in a 1999 Yukon, first, discharge the air conditioning system to safely remove refrigerant. Then, remove the dashboard and disconnect the HVAC unit from the vehicle. After accessing the evaporator coil, unbolt it from the housing, disconnect the refrigerant lines, and replace it with the new coil. Reassemble the HVAC unit, reconnect everything, and recharge the system with refrigerant.
