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.
Inside the unit under the evaporator coil. The condensate drain line is attached to it.
dertty evaporator coil , low charge ,restriction on any of the line condenser fan diffectedType your answer here...
$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.
Don't do it unless you are certified , plus buying R22 you need a certification. Check your evaporator filters , wash your condenser coil.

A "coil" is a length of copper or aluminum tubing that has been wrapped or folded into a compact package. A refrigerant gas, such as Freon or ammonia, is pumped through the coil by the compressor. Air is blown past the turns of a coil to absorb or reject heat. There are two coils in an air conditioning unit, or any refrigeration unit, for that matter -- an evaporator coil inside (gets cold) and a condenser coil outside (gets hot).
The coil that serves the inside of the house is called the indoor coil. The reason is that the indoor coil is a condenser in the heating mode and an evaporator in the cooling mode.. (pg. 1077)
This is a assembly of a coil of copper or alumnium tubing and fins inside the house heater unit that cools down for the furnance blower to send cold air to the living spaces.
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.
