Why is my AC unit not working properly and showing signs of a frozen coil?

Your AC unit may not be working properly and showing signs of a frozen coil due to issues such as low refrigerant levels, restricted airflow, or a malfunctioning thermostat. These issues can cause the coil to freeze, preventing the AC unit from cooling effectively. It is important to have a professional HVAC technician inspect and repair the unit to ensure proper functioning.
