Ice appears in my indoor air conditioning unit, why does this happen?
The ice formation in the indoor unit may occur due to:
- Lack of refrigerant (low suction pressure and low evaporating temperature of the refrigerant).
- Partial obstruction in the expansion device (capillary).
- Defective indoor fan or restriction in the circulation of the air.
- Very dirty air filters, resulting in restriction of the air circulation.
