There are a number of reasons your air conditioner may be freezing up. Your air conditioner must have proper airflow to keep the coils from getting too cold and freezing. Dirty air filters or closed registers may be preventing proper airflow through the system which could cause it to freeze. Other causes could be low refrigerant, improper fan operation, a faulty thermostat, or a drainage issue. Whatever the cause, you should call our team if your system is freezing up and we can identify the problem.
