The low side of an AC unit may be freezing due to restricted airflow, low refrigerant levels, or a faulty expansion valve. This can cause the pressure and temperature in the system to drop, leading to the formation of ice on the coils. It is important to address the root cause of the issue to prevent further damage to the unit.
