Aircon spitting ice can be a frustrating and alarming issue, but understanding the reasons behind it can help you prevent it from happening in the first place.
One major cause of aircon spitting ice is a malfunctioning thermostat, which can lead to the aircon producing excessive cold air and causing the water to freeze into ice.
Aircon spitting ice can also be caused by a dirty air filter, which can restrict airflow and cause the aircon to work harder, leading to ice formation.
Regular cleaning and maintenance of your aircon unit can help prevent ice from forming and reduce the risk of spitting ice.
How Air Conditioners Work
Air conditioners work by using refrigerant to cool the air inside your home. The refrigerant circulates through a system that includes a compressor, condenser coils, and an evaporator coil.
Ice can form on an air conditioner unit when the condenser evaporator coil's temperature falls below freezing. This can happen due to a low level of refrigerant or leakage.

As the refrigerant flows through the system, it absorbs heat from the air, which is then released outside through the condenser coils. If the coils get dirty or clogged, the air conditioner's ability to cool the air is impaired.
Poor airflow is another common issue that can cause the air conditioner to freeze. This can be due to a faulty fan or motor, which can be a problem to fix on your own.
