High Efficiency Media Air Filter
Restricted airflow is the primary cause of coil icing; when air cannot pass over the coil, there is insufficient heat load to boil the refrigerant, causing the coil temperature to plummet below freezing. This specific model requires high-MERV media filters that can easily become occluded by particulate matter, leading to rapid ice accumulation.

All-Aluminum Evaporator Coil
A refrigerant leak reduces the system's mass flow and pressure; lower pressure results in a lower boiling point for the refrigerant, often below 32°F. This causes the coil to freeze progressively from the expansion point until the entire heat exchanger is encased in ice, preventing any cooling or heating of the air stream.

Electronic Expansion Valve (EEV)
The XV20i utilizes an EEV for precise refrigerant metering; if the stepper motor or valve body sticks in a restricted position, it creates a localized pressure drop. This starving of the evaporator coil leads to extremely low temperatures at the coil inlet, which quickly spreads as ice across the entire surface area.
