Why is your ac a coil freezing up?

A coil in your AC can freeze up due to several reasons, including low refrigerant levels, restricted airflow, or a malfunctioning thermostat. Low refrigerant can lead to insufficient heat absorption, causing the coil to freeze. Restricted airflow, often caused by dirty filters or blocked ducts, prevents warm air from circulating around the coil, leading to freezing. Regular maintenance and prompt repairs can help prevent this issue.
