The Science Behind Ice Buildup

Understanding the science behind ice buildup on evaporator coils is key to effective prevention. When warm air passes over the cold evaporator coils, moisture in the air condenses and forms water droplets. This is a normal process in air conditioning. However, if airflow is restricted, the coils can become too cold, causing the water to freeze instead of draining away. This ice buildup can then restrict airflow further, leading to system malfunction and potential leaks. By maintaining optimal airflow and regularly cleaning the coils, you can prevent this issue and ensure efficient system operation.,evaporator coil science,ice buildup causes,prevention strategies
