Why does my window air conditioner spit out ice?
Most window air conditioners have one cooling capacity (‘on’, unless you count ‘off’ as an increment). The fan which moves air across the evaporator (aka cooling coil) may have several speeds. In humid climates, running the fan at low speed increases residence time as the air moves across the coil.
Why does my a / C keep spitting out ice?
If it’s ‘spitting’ ice and not cooling much, it sounds like it could be blocked, probably by accumulated dust. The lack of through airflow means that the heat exchanger on the cold side is getting much too cold because no air is circulating – it’s just cooling the air that’s trapped around it.
Why does ice form in a mini split AC?
When the air passes by them at this temperature, the moisture from the air condenses on the surface of the coil. But because the coil is not quite freezing, the water then runs down into a collection pan. When the coil is too cold, however, the moisture from the air will freeze on the coil before it can run off.
Why does my air conditioner keep icing up?
The most common cause of window air conditioners icing up is a lack of adequate air flow. Room air is drawn over the evaporator coils where it is cooled and then re-circulated back into the room. Insufficient air flow over the evaporator coils will cause them to become too cold.
Why does my air conditioner spit out water and ice?
There’s a point inbetween a full charge of refrigerant, and not enough refrigerant to chill the air. That point is when a little bit low on refrigerant where they are more likely to spit water and ice up.

What happens when the air conditioner coil is too cold?
When the coil is too cold, however, the moisture from the air will freeze on the coil before it can run off. This ice actually manages to insulate the coil and keeps it from properly cooling the air or removing any additional moisture. If left unattended, the ice in your central air conditioning system can cause real damage to the unit.
