To defrost an air conditioner coil, first turn off the unit and switch the thermostat to the "off" position. Allow the ice to melt naturally; you can speed up the process by using a fan to circulate warm air around the unit. Ensure the air filter is clean and the airflow is not obstructed, as poor airflow can lead to freezing in the future. Once defrosted, check for any underlying issues before restarting the unit.

The cost to replace a coil in an air conditioner typically ranges from 500 to 1500, depending on the type of coil and the complexity of the installation.
The average cost of an air conditioner coil replacement is typically between 900 and 2,000, depending on the type of coil and the complexity of the installation.
If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
Vacuum leak
It is just a simple fan blowing over a coil.

Your air conditioner may not be working properly because the AC coil has frozen. This can happen when there is a lack of airflow or a refrigerant leak, causing the coil to become too cold and freeze. This restricts the cooling process and can lead to reduced efficiency or complete failure of the air conditioner.
In an air conditioner, thermal energy is the heat energy that is absorbed from the indoor air by the refrigerant as it evaporates in the evaporator coil. This thermal energy is then released to the outside air as the refrigerant condenses in the condenser coil, cooling the indoor air in the process.
You have a vacuum leak causing your vents to switch from dash to defrost.
The evaporator coil condenses the humidity in the air dehumidifying it.
When you select the defrost setting , the air conditioning compressor will kick in and out to help dehumidify the air , that's normal to hear the compressor kicking in and out
