There are several reasons why an air conditioner might freeze up:
– Restricted airflow due to dirty filters or blocked return air ducts.
– Low refrigerant levels, often caused by leaks.
– Malfunctioning fan motors.
– Dirty or blocked evaporator coils.
If you notice ice on your unit, turn off the AC to prevent further damage and call a professional HVAC technician. Regular maintenance can help prevent such issues.
