Why do coils freeze up on air conditioners? • Low Refrigerant Levels: Not enough refrigerant causes the coils to get too cold. • Poor Airflow: Dirty filters, blocked vents, or a bad blower motor restrict airflow, causing condensation to freeze. • Dirty Coils: Dust and grime on the evaporator coils insulate them, leading to freezing. • Thermostat Issues: If a thermostat keeps running the system without allowing off cycles, freezing can happen. • Mechanical Problems: Things like a stuck expansion valve or bad sensors can cause freezing too. In simple terms: anything that lowers heat transfer or airflow can cause coils to freeze.
