Why does my Austin AC freeze up in the summer?

Frozen evaporator coils in Austin summer heat are almost always caused by: (1) A dirty air filter reducing airflow across the evaporator coil - check and replace your air filter first; (2) Low refrigerant causing the evaporator coil to drop below freezing temperature - requires a technician to locate the leak and recharge; (3) Blower motor failure reducing indoor airflow. Turn the system off and let it thaw 4-6 hours before running it again - running a frozen AC causes compressor damage.
