Why did my AC freeze into a solid block of ice?

Ice forms when either airflow is restricted (severely clogged filter or bad blower motor) or refrigerant levels have dropped due to a coil leak.

What causes the AC outside unit to hum loudly without turning on?

In 85% of cases, this is a failed dual-run capacitor or pitted contactor. We replace these components on the spot within 30 minutes.
