How do you thaw out air conditioner fast?

To quickly thaw out an air conditioner, first turn off the unit and switch the thermostat to the "off" position. Remove any obstructions around the air intake and ensure the filters are clean to improve airflow. You can use a fan to circulate warm air around the unit or place a space heater nearby (but not too close) to speed up the thawing process. Once the ice has melted, check for any underlying issues, such as low refrigerant levels or dirty coils, before turning the AC back on.
